    One way the public can engage in insect conservation is through wildlife gardening, including the growing of insect-friendly flowers as sources of nectar. However, plant varieties differ in the types of insects they attract. To determine which garden plants attracted which butterflies, we counted butterflies nectaring on 11 varieties of summer-flowering garden plants in a rural garden in East Sussex, UK. These plants were all from a list of 100 varieties considered attractive to British butte...

    Full Text Available Rehabilitation of mangrove was required to increase biodiversity and abundance population of fauna, including macrozoobenthos. The aims of this research were to study influence of biotic and abiotic factors to diversity and abundance of macrozoobenthos. This research was conducted on June, 2003 in Great Garden Forest (Tahura Ngurah Rai, Bali. The observation plots were Rhizophora apiculata’s and Rhizophora mucronata’s planted in different plant density. The results of this experiment showed that diversity and abundance of macrozoobenthos were not significant correlation to the density of the plants. The abundance of macrozoobenthos was negatively correlation to substrate texture.

    Full Text Available Botanical gardens' collections of living plants are valuable not only because of their exhibitions, but also because of the data accumulated during introductions of new plants. Inventory allows to collect valuable material about introduction of different types of plants (species and taxa. Analysis of the available information allows to select and recommend advanced species (genus complex for the needs of urbane floristics; the perennial herbaceous plants of mountain areas come in the first place. A new list of advanced ornamental and household plants is introduced in the article. The recommended plants can be used for urban gardening and various groundscape works, and for creation of seed orchards in the neighboring regions. The study of introduction results helps not only to determine the advanced species (and taxa, but to understand which spices will not be able to survive a long time in the new conditions (mainly because of the climate, for example in the North-West of Russia. Over the past 60 years, around 385 plants of 61 families has been introduced at the North American and Himalayan rock gardens of the Peter the Great Botanical Garden. In the 60s of the 20th century, the exposition of these rock gardens had nearly 130 species from 51 families, 20 years later – 254 plants of 55 families. In the beginning of the 21st century, there were 249 taxa of the 52 families. Since 2010, the Alpinarium had to undergo a major reconstruction following the restoration and addition of the collection. As of 2015, the exposition of the North American and Himalayan rock gardens has 200 species of 54 families.

    2017-10-01

    Botanic gardens conserve plant diversity ex situ and can prevent extinction through integrated conservation action. Here we quantify how that diversity is conserved in ex situ collections across the world's botanic gardens. We reveal that botanic gardens manage at least 105,634 species, equating to 30% of all plant species diversity, and conserve over 41% of known threatened species. However, we also reveal that botanic gardens are disproportionately temperate, with 93% of species held in the Northern Hemisphere. Consequently, an estimated 76% of species absent from living collections are tropical in origin. Furthermore, phylogenetic bias ensures that over 50% of vascular genera, but barely 5% of non-vascular genera, are conserved ex situ. While botanic gardens are discernibly responding to the threat of species extinction, just 10% of network capacity is devoted to threatened species. We conclude that botanic gardens play a fundamental role in plant conservation, but identify actions to enhance future conservation of biodiversity.

    Full Text Available Scarabaeidae defoliators are considered of great importance in Brazil because they seriously damage the leaf system of several plant species. The objective of this study was to report the occurrence of the defoliating beetle Bolax campicola Machatschke, 1974 (Coleoptera: Scarabaeidae attacking ornamental plants in the urban area of municipality of Forestal, Minas Gerais State, Brazil. The initial attack was observed on the ornamental palm species Dypsis lutescens (Arecaceae whose leaves were completely consumed, and then these insects began to feed on Canna indica (Cannaceae, another ornamental species, which was found near to the first. However, in the same location newly planted fruit tree seedlings of Plinia trunciflora (Myrtaceae, Averrhoa carambola (Oxalidaceae and Malpighia emarginata (Malpighiaceae were attacked and completely defoliated. This report of damage to plants in urban areas by B. flavolineatus demonstrates the need for studies on the behavior and feeding preference of these insects, and even their ability to adapt to different host plants.

  15. Resolving whether botanic gardens are on the road to conservation or a pathway for plant invasions.

    Hulme, Philip E

    2015-06-01

    A global conservation goal is to understand the pathways through which invasive species are introduced into new regions. Botanic gardens are a pathway for the introduction of invasive non-native plants, but a quantitative assessment of the risks they pose has not been performed. I analyzed data on the living collections of over 3000 botanic gardens worldwide to quantify the temporal trend in the representation of non-native species; the relative composition of threatened, ornamental, or invasive non-native plant species; and the frequency with which botanic gardens implement procedures to address invasive species. While almost all of the world's worst invasive non-native plants occurred in one or more living collections (99%), less than one-quarter of red-listed threatened species were cultivated (23%). Even when cultivated, individual threatened species occurred in few living collections (7.3), while non-native species were on average grown in 6 times as many botanic gardens (44.3). As a result, a botanic garden could, on average, cultivate four times as many invasive non-native species (20) as red-listed threatened species (5). Although the risk posed by a single living collection is small, the probability of invasion increases with the number of botanic gardens within a region. Thus, while both the size of living collections and the proportion of non-native species cultivated have declined during the 20th century, this reduction in risk is offset by the 10-fold increase in the number of botanic gardens established worldwide. Unfortunately, botanic gardens rarely implement regional codes of conduct to prevent plant invasions, few have an invasive species policy, and there is limited monitoring of garden escapes. This lack of preparedness is of particular concern given the rapid increase in living collections worldwide since 1950, particularly in South America and Asia, and highlights past patterns of introduction will be a poor guide to determining future

  18. Most ornamental plants on sale in garden centres are unattractive to flower-visiting insects.

    2017-01-01

    Gardeners and park managers seeking to support biodiversity in urban areas often plant ornamentals attractive to flower-visiting insects. There is a huge diversity of garden plant varieties, and some recommendations are available as to which are attractive to insects. However, these are largely not based on rigorous empirical data. An important factor in consumer choice is the range of varieties available for purchase. In the UK, garden centres are a key link in the supply chain between growers and private gardens. This study is the first to determine the proportions of flowering ornamentals being sold that are attractive to flower-visiting insects. We surveyed six garden centres in Sussex, UK, each over two days in 2015, by making 12 counts of insects visiting patches of each ornamental plant on display for sale that was in bloom. To provide a consistent baseline among different locations, we brought with us and surveyed marjoram ( Origanum vulgare ) plants in pots, which are known to be attractive to a wide range of flower-visiting insects. The attractiveness of plant varieties to insects was then expressed in two ways: the absolute number and relative to that on marjoram ('marjoram score'), both per unit area of plant cover. In addition, we noted whether each variety was recommended as pollinator-friendly either via a symbol on the label, or by being included in the Royal Horticultural Society's 'Perfect for Pollinators' list. Furthermore, we compared the attractiveness of plants that are typically grown for more than one year versus only one year. We surveyed 59-74 plant varieties in bloom across the six garden centres. In each garden centre, the distributions of variety attractiveness were highly skewed to the right, with most varieties being relatively unattractive, and few varieties highly attractive to flower-visiting insects. The median attractiveness of varieties with a recommendation was 4.2× higher than that of varieties without. But, due to the large

  19. The richness of plants in Art Nouveau gardens

    Full Text Available The turn of the 19th and the 20th centuries signified the appearance of a new trend in art called Art Nouveau in England, Stile floreale in Italy, and in Poland – secesja. It was an attempt to escape from the style that copied historical forms and set a new direction of development. The main inspiration for the creators of this period became nature, its asymmetry, variety of textures, subtle colors or smooth, and wavy lines. Artistic motifs were drawn from the richness of native flora and fauna. Flowering shrubs, perennials and creepers were especially inseparable decorative and compositional elements of a garden.  Secession had a significant impact on painting, sculpture, architecture, and garden design. The space surrounding people was treated comprehensively by blurring the boundaries between different arts. A multitude of shrubs – especially roses and lots of perennials such as Lilium, Iris, and Phlox, gave the impression of architecture immersing in the surrounding garden. The aim of the paper was to briefly analyze the Art Nouveau style and present the diversity of species used in the gardens of that period.

    Full Text Available The degradation of live plant biomass in fungus gardens of leaf-cutting ants is poorly characterised but fundamental for understanding the mutual advantages and efficiency of this obligate nutritional symbiosis. Controversies about the extent to which the garden-symbiont Leucocoprinus gongylophorus degrades cellulose have hampered our understanding of the selection forces that induced large scale herbivory and of the ensuing ecological footprint of these ants. Here we use a recently established technique, based on polysaccharide microarrays probed with antibodies and carbohydrate binding modules, to map the occurrence of cell wall polymers in consecutive sections of the fungus garden of the leaf-cutting ant Acromyrmex echinatior. We show that pectin, xyloglucan and some xylan epitopes are degraded, whereas more highly substituted xylan and cellulose epitopes remain as residuals in the waste material that the ants remove from their fungus garden. These results demonstrate that biomass entering leaf-cutting ant fungus gardens is only partially utilized and explain why disproportionally large amounts of plant material are needed to sustain colony growth. They also explain why substantial communities of microbial and invertebrate symbionts have evolved associations with the dump material from leaf-cutting ant nests, to exploit decomposition niches that the ant garden-fungus does not utilize. Our approach thus provides detailed insight into the nutritional benefits and shortcomings associated with fungus-farming in ants.

  3. Botanical Gardens and Collecting of Plants in the Light of the Metamorphosis of Botanical

    2015-12-01

    Full Text Available In the late 18th and early 19th century, the collecting of exotic plants became a fashion that took hold of European courts, and was followed by many noblemen, intellectuals, gardeners and others. It was not only popular to grow new plants in gardens, collecting them in herbaria or illustrating and enumerating them in catalogues, but was also important to develop botanical knowledge to enable the owners of the plants to use and present them. In Carniola we can observe this interest in botany in the cases of Baron Joseph Erberg, Barons Žiga and Karl Zois, Jesuit Gabriel Gruber as well as many others. Baron Erberg's activity is recorded in archives which include lively correspondence concerning plant collecting, the exchange and purchase of plants and other botanical matters. So we can see that among plant lovers in Carniola foreign plants such as pelargonium, agave and hydrangea were popular and that they had a special role in gardens devoted especially to exotic plants. The collecting of exotic plants is not just a phenomenon of the eighteenth and nineteenth centuries but can be traced back to early civilisations such the Assyrians and ancient Chinese and was also notable in a the 16th and 17th centuries with their cabinets of curiosities. But studying the botanical collection of exotic and new (or newly defined plants gardens of the late 18th and early 19th centuries shows us that although we can recognize some of the old “habits” in the process of collecting (collecting of rare, fascinating plants or collecting plants to demonstrate imperial power the social changes in the 18th century left their trace also in this aspect of human activity. Thus we can understand plant collecting of this time as a decline and metamorphosis of the former natural cabinets of curiosities. In botanical gardens of the late 18th and early 19th century we see the development of science of botany, the rise of the amateur botanist, a different perception of nature

  6. Leaf-Cutter Ant Fungus Gardens Are Biphasic Mixed Microbial Bioreactors That Convert Plant Biomass to Polyols with Biotechnological Applications

    Somera, Alexandre F.; Lima, Adriel M.; dos Santos-Neto, Álvaro J.; Lanças, Fernando M.

    2015-01-01

    Leaf-cutter ants use plant matter to culture the obligate mutualistic basidiomycete Leucoagaricus gongylophorus. This fungus mediates ant nutrition on plant resources. Furthermore, other microbes living in the fungus garden might also contribute to plant digestion. The fungus garden comprises a young sector with recently incorporated leaf fragments and an old sector with partially digested plant matter. Here, we show that the young and old sectors of the grass-cutter Atta bisphaerica fungus garden operate as a biphasic solid-state mixed fermenting system. An initial plant digestion phase occurred in the young sector in the fungus garden periphery, with prevailing hemicellulose and starch degradation into arabinose, mannose, xylose, and glucose. These products support fast microbial growth but were mostly converted into four polyols. Three polyols, mannitol, arabitol, and inositol, were secreted by L. gongylophorus, and a fourth polyol, sorbitol, was likely secreted by another, unidentified, microbe. A second plant digestion phase occurred in the old sector, located in the fungus garden core, comprising stocks of microbial biomass growing slowly on monosaccharides and polyols. This biphasic operation was efficient in mediating symbiotic nutrition on plant matter: the microbes, accounting for 4% of the fungus garden biomass, converted plant matter biomass into monosaccharides and polyols, which were completely consumed by the resident ants and microbes. However, when consumption was inhibited through laboratory manipulation, most of the plant polysaccharides were degraded, products rapidly accumulated, and yields could be preferentially switched between polyols and monosaccharides. This feature might be useful in biotechnology. PMID:25911490

    What do a snap-bean plant and a future NASA satellite instrument named TEMPO have in common? They are both indicators of the quality of the air we breathe. Scientists, educators, and museum and student collaborators of the Tropospheric Emissions: Monitoring Pollution (TEMPO) instrument team are developing a program model to engage learners of all ages via public ozone garden exhibits and associated activities. TEMPO, an ultraviolet and visible spectroscopy instrument due for launch on a geostationary host satellite between 2019 and 2021, will scan North America hourly to measure the major elements in the tropospheric ozone chemistry cycle, providing near real-time data with high temporal and spatial resolution. The TEMPO mission provides a unique opportunity to share the story of the effects of air quality on living organisms. A public ozone garden exhibit affords an accessible way to understand atmospheric science through a connection with nature, while providing a visual representation of the impact of ozone pollution on living organisms. A prototype ozone garden exhibit was established at the Virginia Living Museum in partnership with NASA Langley, and has served as a site to formatively evaluate garden planting and exhibit display protocols, hands-on interpretive activities, and citizen science data collection protocols for learners as young as 3 to 10 as well as older adults. The fun and engaging activities, optimized for adult-child interaction in informal or free-choice learning environments, are aimed at developing foundational science skills such as observing, comparing, classifying, and collecting and making sense of data in the context of thinking about air quality - all NGSS-emphasized scientific practices, as well as key capabilities for future contributing members of the citizen science community. As the launch of TEMPO approaches, a major public engagement effort will include disseminating this ozone garden exhibit and program model to a network of

    Plant invasions often follow initial introduction with a considerable delay. The current non-native flora of a region may hence contain species that are not yet naturalized but may become so in the future, especially if climate change lifts limitations on species spread. In Europe, non-native garden plants represent a huge pool of potential future invaders. Here, we evaluate the naturalization risk from this species pool and how it may change under a warmer climate. Europe. We selected all species naturalized anywhere in the world but not yet in Europe from the set of non-native European garden plants. For this subset of 783 species, we used species distribution models to assess their potential European ranges under different scenarios of climate change. Moreover, we defined geographical hotspots of naturalization risk from those species by combining projections of climatic suitability with maps of the area available for ornamental plant cultivation. Under current climate, 165 species would already find suitable conditions in > 5% of Europe. Although climate change substantially increases the potential range of many species, there are also some that are predicted to lose climatically suitable area under a changing climate, particularly species native to boreal and Mediterranean biomes. Overall, hotspots of naturalization risk defined by climatic suitability alone, or by a combination of climatic suitability and appropriate land cover, are projected to increase by up to 102% or 64%, respectively. Our results suggest that the risk of naturalization of European garden plants will increase with warming climate, and thus it is very likely that the risk of negative impacts from invasion by these plants will also grow. It is therefore crucial to increase awareness of the possibility of biological invasions among horticulturalists, particularly in the face of a warming climate.

    The adoption of exotic plants by indigenous herbivores in the region of introduction can be influenced by numerous factors. A botanical garden in Western Siberia was used to test various hypotheses on the adaptation of indigenous phyllophagous insects to exotic plants invasions, focusing on two feeding guilds, external leaf chewers and leaf miners. A total of 150 indigenous and exotic woody plant species were surveyed for insect damage, abundance and species richness. First, exotic woody plants were much less damaged by chewers and leaf miners than native plants, and the leaf miners' species richness was much lower on exotic than native plants. Second, exotic woody plants having a congeneric species in the region of introduction were more damaged by chewers and hosted a more abundant and species-rich community of leaf miners than plants without native congeneric species. Third, damage by chewers significantly increased with the frequency of planting of exotic host plants outside the botanical garden, and leaf miners' abundance and species richness significantly increased with residence time in the garden. Finally, no significant relationship was found between insect damage or abundance and the origin of the exotic plants. Besides the ecological implications of the results, this study also illustrates the potential of botanical gardens to test ecological hypotheses on biological invasions and insect-plant interactions on a large set of plant species.

    Full Text Available Although phosphorus is an essential factor for proper plant growth in natural environments, an excess of phosphate in water sources causes serious pollution. In this paper we describe transgenic plants which hyperaccumulate inorganic phosphate (Pi and which may be used to reduce environmental water pollution by phytoremediation. AtPHR1, a transcription factor for a key regulator of the Pi starvation response in Arabidopsis thaliana, was overexpressed in the ornamental garden plants Torenia, Petunia, and Verbena. The transgenic plants showed hyperaccumulation of Pi in leaves and accelerated Pi absorption rates from hydroponic solutions. Large-scale hydroponic experiments indicated that the enhanced ability to absorb Pi in transgenic torenia (AtPHR1 was comparable to water hyacinth a plant that though is used for phytoremediation causes overgrowth problems.

    Full Text Available Due to fewer bumblebees in rural areas these days, it is necessary to look for alternative habitats for the active protection of these very important pollinators. The research was carried out in The Botanical Garden of Medicinal Plants, in Wrocław, Poland. In the garden, approximately 2000 plant species were cultivated, of which 185 were visited by bumblebees. Amongst them, 57 plant species were deemed very attractive and were determined to be indicators for 7 bumblebee species. Indicator species for bumblebees ranged between 6 for Bombus pratorum to up to 20 for B. pascuorum. Monarda didyma was an indicator plant to 6 recorded bumblebee species. Other indicator plant species for at least 4 bumblebees species were: Origanum vulgare, Lavandula angustifolia, Rhododendron catawbiense, Phacelia tanacetifolia, and Agastache rugosa. Three bumblebee species were found to forage the most on 11 of the flowering plant species. The biggest group of plants were those which were mostly visited by 1-2 bumblebee species. Amongst all recorded indicator plants, 32% were native species.

    Full Text Available The mycorrhizal status of 77 plant species collected from the Mountain Botanical Garden of the Polish Academy of Sciences in Zakopane (southern Poland was surveyed. These plants include rare, endemic and threatened species in the Tatra Mts. (the Western Carpathians and are maintained in the botanical garden in order to develop effective methods of protection and cultivation. Plants belonging to Brassicaceae, Caryophyllaceae, Dryopteridaceae, Juncaceae, Polygonaceae, Rubiaceae and Woodsiaceae families were nonmycorrhizal. 41 species formed AM symbiosis. Spores of nine AMF spccies (Glomeromycota, including Archaeospora trappei, Glomus aggregatum, G. claroideum, G. constrictum, G. deserticola, G. geosponrum, G. microcarpum, G. mosseae and G.rubiforme were isolated for the first time from this region of Poland. In addition, the occurrence of the fine endophyte, G. tenue was detected in roots of 18 species from the study area, although formation of arbuscules by this fungus was observed rarely. AM fungi were sporadically accompanied by dark septate endophytes (DSE. 70% of nonmycorrhizal plant sepcies were devoid of DSE.

    Context Worldwide ethnobotanical research has shown the importance of home gardens as sources of medicinal plants. These resources are worthy of further study in the Argentinean Atlantic Forest due to the richness of medicinal flora and their importance for local people. Objective We studied richness, composition, cultural importance and medicinal uses of plants in home gardens of rural, semirural and urban areas in the Iguazú Department (Misiones, Argentina). Our hypothesis claims that people living in different environments have a similar array of medicinal plants in their gardens and they use them in a similar way. Materials and methods The analysis was based on 76 interviews and plant inventories of home gardens. During guided walks in gardens, voucher specimens were collected. To analyse composition, Simpson similarity index was applied and a new index was proposed to measure culturally salient species. Results All the environments had similar species composition with species differing in less than 30% of them. The most culturally salient taxa were Mentha spicata L. (Lamiaceae), in rural, Artemisia absinthium L. (Asteraceae), in semirural, and Aloe maculata All. (Xanthorrhoeaceae), in urban areas. The body systems treated with medicinal plants were similar across study sites. Discussion The results suggest a "core repertoire" of medicinal plants and a widespread exchange of plants among local population. The cultural importance index informs us about plant adaptability, based on the efficacy and the versatility of medicinal resources. Conclusion In this changing context where mobility and migrations constitute everyday life, medicinal plants in home gardens are part of local healthcare sovereignty.

    Plants represent a large reservoir of organic carbon comprised primarily of recalcitrant polymers that most metazoans are unable to deconstruct. Many herbivores gain access to nutrients in this material indirectly by associating with microbial symbionts, and leaf-cutter ants are a paradigmatic example. These ants use fresh foliar biomass as manure to cultivate gardens composed primarily of Leucoagaricus gongylophorus, a basidiomycetous fungus that produces specialized hyphal swellings that serve as a food source for the host ant colony. Although leaf-cutter ants are conspicuous herbivores that contribute substantially to carbon turnover in Neotropical ecosystems, the process through which plant biomass is degraded in their fungus gardens is not well understood. Here we present the first draft genome of L. gongylophorus, and, using genomic and metaproteomic tools, we investigate its role in lignocellulose degradation in the gardens of both Atta cephalotes and Acromyrmex echinatior leaf-cutter ants. We show that L. gongylophorus produces a diversity of lignocellulases in ant gardens and is likely the primary driver of plant biomass degradation in these ecosystems. We also show that this fungus produces distinct sets of lignocellulases throughout the different stages of biomass degradation, including numerous cellulases and laccases that likely play an important role in lignocellulose degradation. Our study provides a detailed analysis of plant biomass degradation in leaf-cutter ant fungus gardens and insight into the enzymes underlying the symbiosis between these dominant herbivores and their obligate fungal cultivar.

    2017-09-01

    Urban centers are important foci for plant biodiversity and yet widespread planting of wildflower gardens in cities to sustain pollinator biodiversity is on the rise, without full consideration of potential ecological consequences. The impact of intentional wildflower plantings on remnant native plant diversity in urban and peri-urban settings has not received attention, although shared pollinators are likely to mediate several types of biotic interactions between human-introduced plants and remnant native ones. Additionally, if wildflower species escape gardens these indirect effects may be compounded with direct ones. We review the potential positive and negative impacts of wildflower gardens on urban native flowering plants, and we reveal substantial gaps in our knowledge. We present a roadmap for research to address whether wildflower gardens, while benefiting pollinators, could also hasten the extinction of native remnant plants in urban settings, or whether they could have other effects that enrich urban biodiversity. Goals of future wildflower mixes should consider the totality of potential interactions. © 2017 The Authors. New Phytologist © 2017 New Phytologist Trust.

    Premise of the study: Internationally, gardens hold diverse living collections that can be preserved for genomic research. Workflows have been developed for genomic tissue sampling in other taxa (e.g., vertebrates), but are inadequate for plants. We outline a workflow for tissue sampling intended for two audiences: botanists interested in genomics research and garden staff who plan to voucher living collections. Methods and Results: Standard herbarium methods are used to collect vouchers, label information and images are entered into a publicly accessible database, and leaf tissue is preserved in silica and liquid nitrogen. A five-step approach for genomic tissue sampling is presented for sampling from living collections according to current best practices. Conclusions: Collecting genome-quality samples from gardens is an economical and rapid way to make available for scientific research tissue from the diversity of plants on Earth. The Global Genome Initiative will facilitate and lead this endeavor through international partnerships. PMID:27672517

    Full Text Available Insect pollinator abundance, in particular that of bees, has been shown to be high where there is a super-abundance of floral resources; for example in association with mass-flowering crops and also in gardens where flowering plants are often densely planted. Since land management affects pollinator numbers, it is also likely to affect the resultant pollination of plants growing in these habitats. We hypothesised that the seed or fruit set of two plant species, typically pollinated by bumblebees and/or honeybees might respond in one of two ways: 1 pollination success could be reduced when growing in a floriferous environment, via competition for pollinators, or 2 pollination success could be enhanced because of increased pollinator abundance in the vicinity.We compared the pollination success of experimental plants of Glechoma hederacea L. and Lotus corniculatus L. growing in gardens and arable farmland. On the farms, the plants were placed either next to a mass-flowering crop (oilseed rape, Brassica napus L. or field beans, Vicia faba L. or next to a cereal crop (wheat, Triticum spp.. Seed set of G. hederacea and fruit set of L. corniculatus were significantly higher in gardens compared to arable farmland. There was no significant difference in pollination success of G. hederacea when grown next to different crops, but for L. corniculatus, fruit set was higher in the plants growing next to oilseed rape when the crop was in flower.The results show that pollination services can limit fruit set of wild plants in arable farmland, but there is some evidence that the presence of a flowering crop can facilitate their pollination (depending on species and season. We have also demonstrated that gardens are not only beneficial to pollinators, but also to the process of pollination.

    Full Text Available Context: Adverse effects from herbal medicines may be partly due to the association of heavy metals with medicinal plants. Aims: To determine residual levels of Ni, Cr, Pb and Cd in nine selected medicinal plant species and the surrounding soils collected from the Faculty of Pharmacy medicinal garden and College of Health Sciences residential quarters, Amassoma, Bayelsa state, Nigeria. Methods: Nine plant species: Jatropha tanjorensis, Ipomoea batatas, Celosia argentea, Zea mays, Colocasia esculenta, Corchorus olitorius, Vernonia amygdalina, Ocimum gratissimum and Talinum triangulare were collected with their surrounding soil samples. The samples were dried and subjected to atomic absorption spectrophotometry (AAS to determine the heavy metal concentrations. Results: The detection frequencies of heavy metals in medicinal plants were: Cd – 100%, Pb – 11%, Ni – 0% and Cr – 0%. The residential quarter was more contaminated than cultivated medicinal garden. Order of residual concentration in bulk soils was Cr > Cd > Ni > Pb. Bioaccumulation factor ranged from 0 – 25.93 for foliar tissues. Cadmium in plant species ranged from 0.23 to 2.44 µg/g with > 88% exceeding the WHO maximum limit for medicinal plant materials. Conclusions: The heavy metal concentrations in medicinal plants were dependent on the collection sites, plant species and physico-chemical properties of soil. Cd exhibited the greatest bioavailability in the investigated plants and soils. Cd and Pb found in plant foliage were due to uptake from soil and aerial deposition, respectively.

    Full Text Available The role of botanic garden in spread of non-native plant species has concerned of international worldwide. This study aimed to study the extent of non-native plant species from Cibodas Botanical Garden (CBG which invades into natural rainforest. A line transect was made edge-to-interior with 1,600 m in distance from CBG boundary. Result showed that distance from CBG was not significant in correlation with non-native tree and treelet density. Furthermore, presence of existing CBG’s plant collection was not a single aspect which influenced presence and abundance. Three invasive species possibly was escape from CBG and it showed edge-to-interior in stems density, i.e. Cinchona pubescens, Calliandra calothyrsus and Cestrum aurantiacum. The patterns of non-native species were influenced by presence of ditch across transect, existence of human trail, and the other non-native species did not have general pattern of spread distribution. Overall, botanical gardens should minimize the risk of unintentional introduced plant by perform site-specific risk assessment.

    Full Text Available Arsenic (As and lead (Pb are two contaminants of concern associated with urban gardening. In Puerto Rico, data currently is limited on As and Pb levels in urban garden soils, soil metal (loid bioaccessibility, and uptake of As and Pb in soil by edible plants grown in the region. This study examined total and bioaccessible soil As and Pb concentrations and accumulation in 10 commonly grown garden plants collected from three urban community gardens in Puerto Rico. Bioavailability values were predicted using bioaccessibility data to compare site-specific bioavailability estimates to commonly used default exposure assumptions. Total and bioaccessible As levels in study soils ranged from 2 to 55 mg/kg and 1 to 18 mg/kg, respectively. Total and bioaccessible Pb levels ranged from 19 to 172 mg/kg and 17 to 97 mg/kg, respectively. Measured bioaccessibility values corresponded to 19% to 42% bioaccessible As and 61% to 100% bioaccessible Pb when expressed as a percent of total As and Pb respectively. Predicted relative percent bioavailability of soil As and Pb based on measured bioaccessibility values ranged from 18% to 36% and 51% to 85% for As and Pb respectively. Transfer factors (TFs measuring uptake of As in plants from soil ranged from 0 to 0.073 in the edible flesh (fruit or vegetable of plant tissues analyzed and 0.073 to 0.444 in edible leaves. Pb TFs ranged from 0.002 to 0.012 in flesh and 0.023 to 0.204 in leaves. Consistent with TF values, leaves accumulated higher concentrations of As and Pb than the flesh, with the highest tissue concentrations observed in the culantro leaf (3.2 mg/kg dw of As and 8.9 mg/kg dw of Pb. Leaves showed a general but not statistically-significant (α = 0.05 trend of increased As and Pb concentration with increased soil levels, while no trend was observed for flesh tissues. These findings provide critical data that can improve accuracy and reduce uncertainty when conducting site-specific risk determination of

    2017-04-01

    Gardening is a form for citizens to use the ecosystem functions of soils, while simultaneously contributing to the Sustainable Development Goals (SDG) 11, 12 and 15 of the UN. In 2016, 8.4 million people in Germany gardened several times a week and 14.2 million people worked in their garden several times a month*. Furthermore, the "Bundesverband Deutscher Gartenfreunde e.V.", an allotment gardening association, has 947.137 members that use an area of 460 km2 for gardening**. This shows that gardening is a frequent pastime for many people and thus can help achieve the SDG's. Interdisciplinary research in six gardening associations was conducted to investigate soil knowledge and soil use in Southern Germany. Questionnaires and interviews with people that chose gardening as a pastime took place in 2015 and 2016. The respondents were interviewed in the respective garden plot to also observe on-site garden management practices. The combination of sociological and ethnological approaches for investigating the soil scientific research question of soil management practices in leisure gardens is useful to start a public discourse on the importance of soil for society. The evaluation showed that soil use in gardens could contribute to the SDG's 11, 12 and 15. Goal 11 is to make cities resilient and sustainable. Soil use in form of gardening is a bottom-up approach that conserves knowledge on small-scale food production. This is important for the resilience of cities in times of crises, as has been the case during the Great Depression or the World Wars. It is closely connected to Goal 12, the sustainable consumption and production patterns. If gardening activities are sustainable in the use of fertilizers, small-scale sustainability and a resilient soil use that also protects the soil and ground water can be achieved. However, this necessitates cooperation between scientists, gardening societies and the individual gardeners on equal terms. Gardening also affects the

    2016-12-01

    Full Text Available This article offers a preliminary investigation of figurative, metaphorical and linguistic aspects of the garden in Indian English fiction. After providing a short introduction to the symbolism of gardens in the colonial and postcolonial periods, and to the image of the garden in Anglophone Indian literature, the focus will be on the novel The Solitude of Emperors by David Davidar (2007, in order to stress the relevance of both specific phytonyms and common names of plants as important linguistic, cultural and textual indicators employed to construct and convey meanings, often in the form of cognitive metaphors. In this light, the postcolonial garden emerges as a cultural site of hybridity and connection with the past. The examination is undertaken through an interdisciplinary approach that follows and adapts the theories and methods of postcolonial studies, stylistics and narratology (e.g. Kövecses 2002; Jeffries and McIntyre 2010; Sorlin 2014.

  19. Bridging Human and Natural Sciences for a Better Understanding of Urban Floral Patterns: the Role of Planting Practices in Mediterranean Gardens

    Directory of Open Access Journals (Sweden)

    Audrey Marco

    2010-06-01

    Full Text Available Biodiversity research in urban settings constitutes an interdisciplinary field combining both the natural and human sciences. A full understanding of the patterns and processes underlying the dynamic of biodiversity in urban ecosystems needs to include humans in models of ecological functioning. We focus on the planting practices of gardeners to identify the bottom-up and top-down human influences on the floral diversity of the Mediterranean gardens in an urbanizing rural zone. An initial ecological study of cultivated flora in 120 private gardens showing floristic pattern variations along an urbanization gradient was combined with a sociological survey. This survey aimed at collecting reasons for planting in gardens in connection with cultivated species. These reasons were classified into categories and analyzed according to the frequency of cultivated species within the entire gradient. Floristic heterogeneity in gardens, represented by the richness of uncommon species, is predominantly caused by social factors, particularly related to the practices and social networks of gardeners who tend to diversify the range of species that are planted. Floristic uniformity, defined by a high frequency of occurrence of plant species, results not only from social factors but also from natural factors that exert high pressure in the Mediterranean region. This "floristic norm" is also influenced by the urban context, which can modify the expression of natural and social factors and lead to differences in plant species compositions between housing density zones. More generally, these results stress the importance of considering both individual choices and city-level influences through an interdisciplinary approach to understanding the underlying processes that establish urban biodiversity patterns at a small scale.

  20. Assessment of Habitat Suitability Is Affected by Plant-Soil Feedback: Comparison of Field and Garden Experiment.

    Directory of Open Access Journals (Sweden)

    Lucie Hemrová

    Full Text Available Field translocation experiments (i.e., the introduction of seeds or seedlings of different species into different localities are commonly used to study habitat associations of species, as well as factors limiting species distributions and local abundances. Species planted or sown in sites where they naturally occur are expected to perform better or equally well compared to sites at which they do not occur or are rare. This, however, contrasts with the predictions of the Janzen-Connell hypothesis and commonly reported intraspecific negative plant-soil feedback. The few previous studies indicating poorer performance of plants at sites where they naturally occur did not explore the mechanisms behind this pattern.In this study, we used field translocation experiments established using both seeds and seedlings to study the determinants of local abundance of four dominant species in grasslands. To explore the possible effects of intraspecific negative plant-soil feedback on our results, we tested the effect of local species abundance on the performance of the plants in the field experiment. In addition, we set up a garden experiment to explore the intensity of intraspecific as well as interspecific feedback between the dominants used in the experiment.In some cases, the distribution and local abundances of the species were partly driven by habitat conditions at the sites, and species performed better at their own sites. However, the prevailing pattern was that the local dominants performed worse at sites where they naturally occur than at any other sites. Moreover, the success of plants in the field experiment was lower in the case of higher intraspecific abundance prior to experimental setup. In the garden feedback experiment, two of the species performed significantly worse in soils conditioned by their species than in soils conditioned by the other species. In addition, the performance of the plants was significantly correlated between the two

    The French Intensive approach to truck gardening has the potential to provide substantially higher yields and lower per acre costs than do conventional farming techniques. It was the intent of this grant to show that there is the potential to accomplish the gains that the French Intensive method has to offer. It is obvious that locally grown food can greatly reduce transportation energy costs but when there is the consideration of higher efficiencies there will also be energy cost reductions due to lower fertilizer and pesticide useage. As with any farming technique, there is a substantial time interval for complete soil recovery after there have been made substantial soil modifications. There were major crop improvements even though there was such a short time since the soil had been greatly disturbed. It was also the intent of this grant to accomplish two other major objectives: first, the garden was managed under organic techniques which meant that there were no chemical fertilizers or synthetic pesticides to be used. Second, the garden was constructed so that a handicapped person in a wheelchair could manage and have a higher degree of self sufficiency with the garden. As an overall result, I would say that the garden has taken the first step of success and each year should become better.

  2. Contamination from polycyclic aromatic hydrocarbons (PAHs) in the soil of a botanic garden localized next to a former manufacturing gas plant in Palermo (Italy)

    2010-01-01

    The Botanical Garden lies within the city of Palermo, a few meters away from one of the largest unused Manufacturing Gas Plant in Sicily. The total concentrations of PAHs (23 compounds) in the soil of Botanical Garden ranged from 947 to 18,072 μg/kg. The wide range of PAH concentrations (RSD = 84%) found in the soil samples indicates heterogeneous levels of contamination in the area and this can be explained by considering the different tree distributions which prevents the homogeneous deposition of pollutants on the soil. Soils collected in the Botanical Garden generally showed the highest PAH concentrations, being almost 2-3 times higher than the concentration samples obtained in the urban reference sites and about 20 times higher than those in the rural stations. The total PAH concentrations, in the Botanical Garden soil, resulted higher than the maximum concentrations allowed by the Italian legislation for the green areas. Perylene, was found in all the stations. From a careful study of the isomeric ratios, we can hypothesize that the soils of the Botanical Garden are mainly affected by localized MGP particulate deposition, suggesting that the partitioning between organic matter and PAHs is not the dominant process in the soils with higher organic matter content.

    Private domestic gardens contribute substantially to the biodiversity of urban areas and benefit human health and well-being. We previously reported a study of 267 gardens across five cities in the United Kingdom in which variation in geographical and climatic factors had little bearing on the richness, diversity and composition of plant species. We therefore hypothesise that garden management is an important factor in determining garden characteristics. Here, from the same sample of gardens, we investigate potential associations between the uses to which people put their gardens, the types of management activities they undertake, and the characteristics of those gardens. Householders (n = 265) completed a questionnaire detailing various aspects of garden use and management activities. The majority of respondents used their gardens chiefly for relaxation, recreation, and eating. Fewer than one fifth included "gardening" amongst their garden uses even though all performed some garden management, suggesting that not all management activity resulted from an interest in gardening. Garden-watering and lawn-mowing were the most prevalent activities and were predictors of other types of management including weeding, vegetation-cutting, leaf-collection, and dead-heading flowers. A number of these activities were associated with one another, the richness and composition of plant species, and the number of land uses in gardens. However, relationships between management activities and the amount of tall vegetation were less consistent, and garden management appeared to be independent of garden area. More species of amphibians, birds, and mammals were observed in gardens with ponds and in which efforts were made to attract wildlife, particularly by providing drinking water. This study supports the hypothesis that garden use and management is associated with garden characteristics.

    Full Text Available Plants provide people with vital resources necessary to sustain life. Nutrition, vitamins, calories, oxygen, fuel, and medicinal phytochemicals are just a few of the life-supporting plant products, but does our relationship with plants transcend these physical and biochemical products? This review synthesizes some of the extant literature on people-plant interactions, and relates key findings relevant to space exploration and the psychosocial and neurocognitive benefits of plants and nature in daily life. Here, a case is made in support of utilizing plant-mediated therapeutic benefits to mitigate potential psychosocial and neurocognitive decrements associated with long-duration space missions, especially for missions that seek to explore increasingly distant places where ground-based support is limited.

    Full Text Available Species Composition and Structure of the Communities of Plant-Parasitic and Free-Living Soil Nematodes in the Greenhouses of Botanical Gardens of Ukraine. Gubin, A. I., Sigareva, D. D. — In greenhouses of botanical gardens of Ukraine 81 species of nematodes were found. The richest by the number of species was Tylenchida order that was presented by 25 species (31 % of species composition. The dominant group of nematodes was plant-parasitic (most frequent was Rotylenchus robustus (de Man, 1876 Filipjev, 1936 and Meloidogyne incognita (Kofoid et White, 1919 Chitwood, 1949. The group of saprobiotic nematodes, which was presented by 52 species (64 %, appeared to be the richest by the number of species. It is shown, that formation of nematode communities in greenhouses of botanical gardens was caused by the interaction of many related factors, crucial of which is the composition of plant collections. The structure of communities is quite constant and almost independent of the quantity of nematodes species. Plant-parasitic species dominate by the number and frequency of detection, and represent a kind of a core of nematode communities.

    The phenology of three genera of desert plants (viz., Calligonum L., Haloxylon L., and Tamarix L.) was investigated in response to temperature changes in Turpan. Eremophytes Botanical Garden The temperature was raised gradually from 1977 to 2006, while the phenophases of Calligonum L., Haloxylon L., and Tamarix L. genera were slowly and insignificantly changed in the study area. Their phenophase were similar and did not change significantly over the duration of the study except the beginning of flowering of the average of the three genera from 1977 to 1990 and 1991 to 2006, respectively. The summed temperature of the first four months was the major factor that affected the spring and flowering phenophases of the respective genera. The bud of Calligonum species was expanded during 1977 to 1990 and 1991 to 2006, the flower-buds in Tamarix species appeared during 1977 to 2006, the fruit setting of Haloxylon species started 1990 to 2006 and leaf discoloration of Tamarix species appeared during 1977 to 1990.

    The aim of the present study was to examine Air Pollution Tolerance Index (APTI) of some climber plant species to develop vertical gardens in Varanasi city which has characteristics of tall building and narrow roads. This condition results in street canyon like structure and hinders the vertical dispersal of air pollutants. We have selected 24 climber plant species which are commonly found in of Varanasi city. Chosen plants can be easily grown either in planter boxes or directly in the ground, with a vertical support they can climb on walls to form green walls or vertical garden. Air Pollution Tolerance Index (APTI) of the selected plant species was calculated and plants with higher APTI are recommended for the development of Vertical garden. Highest APTI was noted for Ipomoea palmata (25.39) followed by Aristolochia elegans (23.28), Thunbergia grandiflora (23.14), Quisqualis indica (22.42), and Clerodendrum splendens (22.36). However, lowest APTI value (8.75) was recorded for the species Hemidesmus indicus. Moreover, the linear regression analysis has revealed a high positive correlation between APTI and ascorbic acid content (R 2 =0.8837) and positive correlation between APTI and Chlorophyll content (R 2 =0.6687). On the basis of higher APTI values (greater than 17), nine species of climber plants viz. I. palmata, T. grandiflora, C. splendens, A. elegans, Q. indica, Petria volubilis, Antigonon leptopus, Cryptolepis buchuanni and Tinospora cordifolia have been recommended to develop vertical greenery systems in a compact tropical city.

  18. Plant/soil concentration ratios for paired field and garden crops, with emphasis on iodine and the role of soil adhesion

    International Nuclear Information System (INIS)

    Sheppard, S.C.; Long, J.M.; Sanipelli, B.

    2010-01-01

    In the effort to predict the risks associated with contaminated soils, considerable reliance is placed on plant/soil concentration ratio (CR) values measured at sites other than the contaminated site. This inevitably results in the need to extrapolate among the many soil and plant types. There are few studies that compare CR among plant types that encompass both field and garden crops. Here, CRs for 40 elements were measured for 25 crops from farm and garden sites chosen so the grain crops were in close proximity to the gardens. Special emphasis was placed on iodine (I) because data for this element are sparse. For many elements, there were consistent trends among CRs for the various crop types, with leafy crops > root crops ≥ fruit crops ∼ seed crops. Exceptions included CR values for As, K, Se and Zn which were highest in the seed crops. The correlation of CRs from one plant type to another was evident only when there was a wide range in soil concentrations. In comparing CRs between crop types, it became apparent that the relationships differed for the rare earth elements (REE), which also had very low CR values. The CRs for root and leafy crops of REE converged to a minimum value. This was attributed to soil adhesion, despite the samples being washed, and the average soil adhesion for root crops was 500 mg soil kg -1 dry plant and for leafy crops was 5 g kg -1 . Across elements, the log CR was negatively correlated with log Kd (the soil solid/liquid partition coefficient), as expected. Although, this correlation is expected, measures of correlation coefficients suitable for stochastic risk assessment are not frequently reported. The results suggest that r ∼ -0.7 would be appropriate for risk assessment. -- Research highlights: →There are few studies that compare CRs among plant types that encompass both field and garden crops.

    Inland vertebrate predators could enrich of nutrients the local top soils in the area surrounding their nests and dens by depositing faeces, urine, and prey remains and, thus, alter the dynamics of plant populations. Surprisingly, and in contrast with convincing evidence from coastal habitats, whether and how this phenomenon occurs in inland habitats is largely uncertain even though these habitats represent a major fraction of the earth's surface. We investigated during two consecutive breeding seasons the potential enrichment of the top-soils associated with inland ground-nesting eagle owls Bubo bubo, as well as its possible consequences in the growth of two common annual grasses in southern Spain. Top-soils associated with owl nests differed strongly and significantly from control top-soils in chemical parameters, mainly fertility-related properties. Specifically, levels of available phosphorus, total nitrogen, organic matter, and available potassium were 49.1, 5.6, 3.1, and 2.7 times higher, respectively, in top-soils associated with owl nests as compared to control top-soils. Germination experiments in chambers indicated that nutrient enrichment by nesting owls enhanced seedling growth in both annual grasses (Phalaris canariensis and Avena sativa), with seedling size being 1.4-1.3 times higher in owl nest top-soils than in control top-soils. Our experimental study revealed that pervasive inland, predatory birds can profoundly enrich the topsoil around their nests and, thus, potentially enhance local vegetation growth. Because diverse inland vertebrate predators are widespread in most habitats they have a strong potential to enhance spatial heterogeneity, impinge on plant communities, and exert an overlooked effect on primary productivity worldwide.

    Since ancient times the relationship between mankind and plants occupies medicine and philosophy. From the first tablets of herbal medicine to Asclepius gardens, those of cloisters and bimaristans to cosmological gardens in Asia, from the largest public park to asylum institutions of the nineteenth century, the garden is proposed as a place of care, a promoter of restoration of the human being. If the advent of technology and drugs have for a time relegated it to the level of empirical care, results in neuroscience ultimately provide it on a scientific basis. The early evolutionary theories, the Savanah theory from Orians, the biophilia hypothesis from Wilson, are relayed by the famous Ulrich' study showing the positive influence of a view of nature through the window on the recovery of in patients. Mechanisms leading stress regulation, level of attention and organisation, focus and fascination, are recognized at the origin of restoration processes. Human capacities to respond to the recuperating function of a natural environment connect to grounded behaviour for adaptation to natural selection process and survival. The mechanisms of our immune system are essential to maintain our vitality. Phyto-resonance, felt or unconsciously perceived in appearance, according to Shepard is an emotion that structures well beyond the archaic behaviour. Recovery, in terms of phenomenological experience of the presence, is a philosophical demonstration of the environmental i.e. multisensory, spatial and temporal approach. Its emotional and affective experience connects to the vitality and creativity. The phyto-resonance hypothesis according to the Konrad Neuberger's point of view induces strategies catering to all levels of the organisation of the human being. It confirms the multidisciplinary nature of hortitherapy and places the mechanism of relationships between man and plant at the centre of discipline. It is also a source of inspiration and inexhaustible work for caregivers

    Can high school gardens in cold climates influence vegetable intake in the absence of nutrition education? This study followed a before/after design where student tray-waste data were collected using the quarter-waste method. The study took place March-April 2012 in a high school in upstate New York. The subjects were 370 enrolled high school students that purchased lunch from the school cafeteria. Prior to the introduction of garden greens in the salad, salads were served as usual. On April 24, harvested greens were included in the salad, and changes in selection and plate waste were measured. When the salad bar contained garden produce, the percentage of students selecting salad rose from 2% to 10% (p school gardens increased selection and intake of school-raised produce. Although a third was not eaten, it is promising to see that still more produce was consumed compared to the past. ©2015 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    The ion-beam breeding developed by the Ring cyclotron of RARF is highly effective to create new flower cultivars within a short duration. A new type of garden plants 'Temari' series (verbena hybrida) keeps many flower clusters from spring until autumn, however 'Coral Pink' of this series shows poor flower clusters. To improve 'Coral Pink' using the ion-beam irradiation. sixty four single nodes were cultured in one plastic dish which was treated with 1-10 Gy of the N-ion beam at 135 MeV/u. Finally, four mutant lines with rich blooming were successfully selected. These mutants grew well compared to host plant, and kept many flower clusters even in autumn. The best mutant had larger number of flower clusters than the host plant in the pot-planting test so that it was released to the market in 2002 with a level of several hundred thousand pots. The development period of the new 'Coral Pink' was only three years. The similar successful cases were demonstrated by the new Dahlia World' (2002), the new Verbena 'Sakura' (2003) and the new Petunia 'Rose' (2003). Thus, we conclude that the ion beam irradiation is an excellent tool for mutation breeding to improve horticultural and agricultural crops with high efficiency. (author)

    Experimental research shows that there are perceived and actual benefits to spending time in natural spaces compared to urban spaces, such as reduced cognitive fatigue, improved mood, and reduced stress. Whereas past research has focused primarily on distinguishing between distinct categories of spaces (i.e., nature vs. urban), less is known about variability in perceived restorative potential of environments within a particular category of outdoor spaces, such as gardens. Conceptually, gardens are often considered to be restorative spaces and to contain an abundance of natural elements, though there is great variability in how gardens are designed that might impact their restorative potential. One common practice for classifying gardens is along a spectrum ranging from "formal or geometric" to "informal or naturalistic," which often corresponds to the degree to which built or natural elements are present, respectively. In the current study, we tested whether participants use design informality as a cue to predict perceived restorative potential of different gardens. Participants viewed a set of gardens and rated each on design informality, perceived restorative potential, naturalness, and visual appeal. Participants perceived informal gardens to have greater restorative potential than formal gardens. In addition, gardens that were more visually appealing and more natural-looking were perceived to have greater restorative potential than less visually appealing and less natural gardens. These perceptions and precedents are highly relevant for the design of gardens and other similar green spaces intended to provide relief from stress and to foster cognitive restoration.

    In France and all over the world, there is no systematic data available on the quality (fertility and contamination) of garden soils. Nevertheless, there is a growing need for a typology and for a method dedicated to national and international garden soil survey. This inventory is much needed in the context of environmental risk assessment, to predict the potential impact on human health of the direct contact with garden soils and of the consumption of vegetables from gardens. The state of the art on the international knowledge on garden soils, gardening practices and food production, shows that gardens remain poorly known and very complex ecological, economical and social systems. Their global quality is the result of a wide number of factors including environment, history, specific characteristics of the gardens, gardeners and their practices, plant and/or animal productions and socio-economic context. The aim is then to better know the determinism of the agronomic, environmental and sanitary properties of gardens as a function of gardening practices and their impact on the quality of soils and plants. We propose a definition of "garden" and more generally of all the field "garden". The system "garden" is represented by attributes (soil and plant characteristics) and factors with various impacts (e.g. environment > soil parent material > former land uses > age and sex of gardener > gardening practices > socio-professional group > type and proportion of productions > climate > age of the garden > size of the garden > education, information > cultural origin > functions of the garden > regulations). A typology of gardens including 7 selected factors and associated categories and a method for describing, sampling and characterizing a population of gardens representative (for a country) are proposed. Based on the statistical analysis on regional databases, we have determined and proposed an optimum size for the collected population of garden soils. The discussion of

    Impingement of fish at cooling-water intakes of 20 power plants located on the Great Lakes has been surveyed and data are presented. Descriptions of site, plant, and intake design and operation are provided. Reports in this volume summarize impingement data for individual plants in tabular and histogram formats. Information was available from differing sources such as the utilities themselves, public documents, regulatory agencies, and others. Thus, the extent of detail in the reports varies greatly from plant to plant. Histogram preparation involved an extrapolation procedure that has inadequacies. The reader is cautioned in the use of information presented in this volume to determine intake-design acceptability or intensity of impacts on ecosystems. No conclusions are presented herein; data comparisons are made in Volume IV

    Urban ecology is emerging as an integrative science that explores the interactions of people and biodiversity in cities. Interdisciplinary research requires the creation of new tools that allow the investigation of relations between people and biodiversity. It has been established that access to green spaces or nature benefits city dwellers, but the role of species diversity in providing psychological benefits remains poorly studied. We developed a user-friendly 3-dimensional computer program (Virtual Garden [www.tinyurl.com/3DVirtualGarden]) that allows people to design their own public or private green spaces with 95 biotic and abiotic features. Virtual Garden allows researchers to explore what elements of biodiversity people would like to have in their nearby green spaces while accounting for other functions that people value in urban green spaces. In 2011, 732 participants used our Virtual Garden program to design their ideal small public garden. On average gardens contained 5 different animals, 8 flowers, and 5 woody plant species. Although the mathematical distribution of flower and woody plant richness (i.e., number of species per garden) appeared to be similar to what would be expected by random selection of features, 30% of participants did not place any animal species in their gardens. Among those who placed animals in their gardens, 94% selected colorful species (e.g., ladybug [Coccinella septempunctata], Great Tit [Parus major], and goldfish), 53% selected herptiles or large mammals, and 67% selected non-native species. Older participants with a higher level of education and participants with a greater concern for nature designed gardens with relatively higher species richness and more native species. If cities are to be planned for the mutual benefit of people and biodiversity and to provide people meaningful experiences with urban nature, it is important to investigate people's relations with biodiversity further. Virtual Garden offers a standardized

    This presentation focuses on the use of low rank coals to form synfuels. A worldwide abundance of low rank coals exists. Large deposits in the United States are located in Texas and North Dakota. Low rank coal deposits are also found in Europe, India and Australia. Because of the high moisture content of lignite ranging from 30% to 60% or higher, it is usually utilized in mine mouth applications. Lignite is generally very reactive and contains varying amounts of ash and sulfur. Typical uses for lignite are listed. A commercial application using lignite as feedstock to a synfuels plant, Dakota Gasification Company's Great Plains Gasification Plant, is discussed

    Full Text Available Many cucurbits, such as cucumbers, squashes and pumpkins, depend on pollinating bees in order to set fruit. However, fruit yield and progeny vigor in these plants generally decreases as heterospecific pollen deposition increases. We studied how the spatial area dedicated to cucumbers (Cucumis sativis, versus other flowering plants, influenced the deposition of conspecific and heterospecific pollen on cucumber plants in New York City community gardens. We also examined the effect of garden size on conspecific and heterospecific pollen deposition on cucumber plants. Female flowers were collected from potted cucumber plants that had been experimentally placed into the gardens, specifically for this study, or that were established in raised beds by members of the community garden. In the laboratory, pollen grains were isolated from the flower by acetolysis, and the number of heterospecific and conspecific cucumber pollen grains were quantified. Conspecific pollen deposition was positively and significantly associated with the size of a community garden, as well as with the area of each garden dedicated to non-cucumber, flowering plants (i.e. floral cover and the area of each garden dedicated to cucumber plants (i.e. cucumber cover. Although floral cover explained a greater proportion of the variance, cucumber cover had the strongest effect on conspecific pollen deposition. Heterospecific pollen deposition was positively and significantly related to garden area. However, no significant relationship was found between heterospecific pollen deposition and floral cover, or cucumber cover. Based upon these results, we hypothesize that floral cover positively impacts conspecific pollen deposition by attracting a greater number of pollinators into an urban garden, and that total cucumber area positively impacts conspecific pollen deposition when pollinators are locally foraging within a garden. We suggest that the arrangement of plants within a garden can

Agriculture of this area is extreme internal variability and complexity, with a multiplicity of highly localized providing the habitats and agricultural lands for much genetic erosion of crop varieties, animals, plants, fungi, and other life forms for wild plant resources. Historically, Kazbegi producers had begun cultivating the land to prepare for planting in of distribution local varieties of wheat, barley, rye, oats, etc. In the only cereals, legumes, herbs and some fruits are cultivated in alpine zone as the upper limit till the location of 2160 m a.s.l. Genetic erosion has been determined historically of aboriginal crops from sheep and cattle grazing problem and reached extreme levels from 1970s in Kazbegi Municipality and causes a problem to maintain agriculture. Plant resources remained in forests and subalpine grasslands and shrub lands. The problems of these materials are habitat degradation by disturbance in many forest types with destroyed and burned. Tree seedlings are grazing by animals and forest is not restoring naturally. Forest planting is good relation for restoration of plant wild species resources. Investigation on exchange on mountain agriculture and plant resources will now be rapidly accelerated in the vital interests of mountain communities.

    2001-06-01

    Two hundred and fifty years ago, the Swedish naturalist Carolus Linnaeus (1707-1778) published his Philosophia botanica. This textbook in botanical science was widely read well into the 19th century. Today it is remembered mainly for two things: the introduction of binomial nomenclature and the formulation of a fixist and creationist species concept. While the former achievement is seen as a practical tool, still applicable for purposes of identification and information retrieval, the latter is usually deemed to have been one of the main obstacles to scientific progress in biology. That both achievements were not independent of each other, but interlocked theoretically and grounded in a specific scientific practice still thriving today--the collection of plant specimens in botanical gardens--is usually overlooked. The following article tries to uncover these connections and to demonstrate the significance that Linnaeus' achievements had for modern biology.

    Lampung is one area in Indonesia which has a traditional culture that comes from two groups of descents, they are ulun Lampung Pepadun and ulun Lampung Saibatin. Lampungnese traditional culture has been well-known by Indonesian people for its traditional dances, traditional clothing, or traditional home architecture. However, Lampungnese traditional home garden recently may not yet been described. Information related to Lampungnese traditional home garden is still very limited and it does not yet represented the culture based design concept. This research was directed to identify the elements of the home garden and map it into design concept of the Lampungnese traditional home garden based on information of Lampungnese traditional culture. The study was conducted by using descriptive approach through literature review, interviews and cultural exploration, as well as field observation. The study was able to identify the elements forming the Lampungnese traditional home garden, namely gakhang hadap, walai, outdoor kitchenette, firewood place, outdoor kitchen, livestock barns, as well as plants. Space layout of the home garden comprises front yard (tengahbah/terambah/beruan), side yard (kebik/kakebik), and backyard (kudan/juyu/kebon). Each element of the garden is located in the right place of the space layout.

    Willet M. Hays was a great benefactor to plant breeding and the founder of the American Genetic Association (AGA). We commemorate the AGA's centennial. We mined university archives, U.S. Department of Agriculture (USDA) yearbooks, plant breeding textbooks, scientific periodicals, and descendants for information. Willet Hays first recognized the individual plant as the unit of selection and started systematic pure-line selection and progeny tests in 1888. He developed useful plant breeding methods. He selected superior flax (Linum usitatissimum L.), wheat (Triticum vulgare L.), corn (Zea mays L.), barley (Hordeum vulgare L.), and oat (Avena sativa L.) varieties, and discovered Grimm alfalfa (Medicago sativa L.); all became commercially important. He initiated branch stations for better performance testing. Willet Hays befriended colleagues in other universities, in federal stations, in a London conference, and in Europe. He gathered and spread the scientific plant breeding gospel. He also improved rural roads and initiated animal breeding records and agricultural economics records. He started the AGA in 1903, serving as secretary for 10 years. He became assistant secretary of agriculture in 1904. He introduced the project system for agricultural research. He authored or coauthored the Nelson Amendment, the Smith-Lever Act, the Smith-Hughes Act, and the protocol leading to the United Nations Food and Agriculture Organization-all involved teaching agricultural practices that improved the world.

  16. Ecology: 'Devil's gardens' bedevilled by ants.

    'Devil's gardens' are large stands of trees in the Amazonian rainforest that consist almost entirely of a single species, Duroia hirsuta, and, according to local legend, are cultivated by an evil forest spirit. Here we show that the ant Myrmelachista schumanni, which nests in D. hirsuta stems, creates devil's gardens by poisoning all plants except its host plants with formic acid. By killing these other plants, M. schumanni provides its colonies with abundant nest sites--a long-lasting benefit as colonies can live for 800 years.

    Full Text Available In the study, it is aimed to reveal current features and practices of the gardens of the preschool education institutions, the obstacles to being qualified gardens in the schools and professional trainings related to the gardens which the teachers want to participate in. The population of the study consists of the teachers working in preschool education institutions in 2014-2015 academic years. The sample of the study consists of 56 preschool teachers who have been willing to participate in the study in the preschool education institutions under the Ministry of National Education which have been selected randomly from the population. The study is a survey study, and a questionnaire form has been prepared by the researchers by investigating related domestic and foreign literature to analyze the views of the teachers related to gardens. The questionnaire form consisted of sections like general information, garden features and applications of the schools, obstacles to gardens in the schools, professional trainings related to garden that the teachers want to participate in. In the analysis of the data obtained in the direction of the goals of the study, frequency and percentage distribution from descriptive statistical techniques have been used. As a result of the research, it was determined that half of the schools had the garden and the other half did not have the garden. Teachers have stated that the majority of school gardens use grasses, wild habitats and ornamental plants, use more than half of the school gardens for activities, and that these activities are mostly play, movement, science and field trips. The majority of teachers reported budget deficiencies and inadequate space as obstacles to the quality gardening of schools. In addition, they reported that the majority of them want to participate in professional training fields related to garden-based teaching such as outdoor classroom management, language and math, nutrition, science and

  18. Incorporating biodiversity into rangeland health: Plant species richness and diversity in great plains grasslands

    Symstad, Amy J.; Jonas, Jayne L.

    2011-01-01

    Indicators of rangeland health generally do not include a measure of biodiversity. Increasing attention to maintaining biodiversity in rangelands suggests that this omission should be reconsidered, and plant species richness and diversity are two metrics that may be useful and appropriate. Ideally, their response to a variety of anthropogenic and natural drivers in the ecosystem of interest would be clearly understood, thereby providing a means to diagnose the cause of decline in an ecosystem. Conceptual ecological models based on ecological principles and hypotheses provide a framework for this understanding, but these models must be supported by empirical evidence if they are to be used for decision making. To that end, we synthesize results from published studies regarding the responses of plant species richness and diversity to drivers that are of management concern in Great Plains grasslands, one of North America's most imperiled ecosystems. In the published literature, moderate grazing generally has a positive effect on these metrics in tallgrass prairie and a neutral to negative effect in shortgrass prairie. The largest published effects on richness and diversity were caused by moderate grazing in tallgrass prairies and nitrogen fertilization in shortgrass prairies. Although weather is often cited as the reason for considerable annual fluctuations in richness and diversity, little information about the responses of these metrics to weather is available. Responses of the two metrics often diverged, reflecting differences in their sensitivity to different types of changes in the plant community. Although sufficient information has not yet been published for these metrics to meet all the criteria of a good indicator in Great Plains Grasslands, augmenting current methods of evaluating rangeland health with a measure of plant species richness would reduce these shortcomings and provide information critical to managing for biodiversity.

    Vascular plants in the western Tibetan Plateau reach 6000 m--the highest elevation on Earth. Due to the significant warming of the region, plant ranges are expected to shift upwards. However, factors governing maximum elevational limits of plant are unclear. To experimentally assess these factors, we transplanted 12 species from 5750 m to 5900 m (upper edge of vegetation) and 6100 m (beyond range) and monitored their survival for six years. In the first three years (2009-2012), there were plants surviving beyond the regional upper limit of vegetation. This supports the hypothesis of dispersal and/or recruitment limitation. Substantial warming, recorded in-situ during this period, very likely facilitated the survival. The survival was ecologically a non-random process, species better adapted to repeated soil freezing and thawing survived significantly better. No species have survived at 6100 m since 2013, probably due to the extreme snowfall in 2013. In conclusion, apart from the minimum heat requirements, our results show that episodic climatic events are decisive determinants of upper elevational limits of vascular plants.

    Understanding the functional diversity of home gardens and their socio-ecological determinants is essential for mainstreaming these agroforestry practices into agrobiodiversity conservation strategies. This paper analyzed functional diversity of home gardens, identified the socio-ecological drivers of functions assigned to them, and assessed the agrobiodiversity benefits of home gardens functions. Using data on occurring species in home garden (HG) and functions assigned to each species by the gardeners, the study combined clustering and discriminant canonical analyses to explore the functional diversity of 360 home gardens in Benin, West Africa. Next, multinomial logistic models and chi-square tests were used to analyze the effect of socio-demographic characteristics of gardeners (age, gender, and education level), agro-ecological zones (humid, sub-humid, and semi-arid), and management regime (single and multiple managers) on the possession of a functional type of home gardens. Generalized linear models were used to assess the effect of the functions of home gardens and the determinant factor on their potential in conserving agrobiodiversity. Seven functional groups of home gardens, four with specific functions (food, medicinal, or both food and medicinal) and three with multiple functions (more than two main functions), were found. Women owned most of home gardens with primarily food plant production purpose while men owned most of home gardens with primarily medicinal plant production purposes. Finding also showed that multifunctional home gardens had higher plant species diversity. Specifically, crops and crop wild relatives occurred mainly in home gardens with food function while wild plant species were mostly found in home gardens with mainly medicinal function. Home gardening is driven by functions beyond food production. These functions are mostly related to direct and extractive values of home gardens. Functions of home gardens were gendered, with women

    Full Text Available Within this study, the art of gardening in Ottoman Turks has been examined in four periods: 1. The period starting with the establishment of the Ottoman Empire till the conquest of the Byzantine capital of Constantinople by the Turks (1300-1453 2. The period starting with the conquest of Istanbul till the Tulip Era (1706 3. The Tulip Era (1703-1730 4. The period starting with the Tulip Era (1730 till the establishment of the Republic (1923 In the first period, Ottoman Turks remained under the influence of Seljuk art and were partly in contact with the Byzantine works. When miniatures showing the palace life are examined, often the importance given to the atrium garden could be seen. A significant development in the art of gardening was experienced during the period starting with the conquest of Istanbul till the Tulip Era. The Tulip Era has been a very productive period in terms of fine art in Ottoman history. Major improvements and innovations in poetry, literature, music, civil architecture and especially in the art of gardening has emerged. Till the Tulip Era, the unique natural landscape of Istanbul was equipped with the top works of art of Ottoman Turks. The art of gardening in Ottoman Turks has entered a new period with the end of the Tulip Era in 1730. This period, has been the period in which foreign influence started to affect Ottoman gardens. The most important works of the second period; the Topkapı Palace Garden and the Yıldız Palace garden, which was mostly established in a natural layout and has been the latest example of Ottoman palace gardening, were examined within this study. The structuring of the Ottoman gardens has changed and developed during the historical process depending on various effects such as life styles of the period and the artistic-cultural structure of the period.

    Bees and other pollinating insects are the important parts of biodiversity due to their great role in plant reproduction and crop production. To explore the role of city garden in native bees conservation, activity patterns, visiting behaviors and flowering plants with nectar or pollen were recorded in south Sichuan in winter. The results showed that, worker bees (Apis cerana cerana) were active to collect food out hive under suitable weather conditions, the duration of working was long. Peaks of the number of outgoing, entrance and foragers without pollen appeared at 14:00-15:00, and bimodal patterns were observed. While, peak of bees with pollen appeared at 11:00, and a unimodal pattern was observed. Time significantly affected the activity of workers. The workload of honey bees on nectar and pollen collection were different, just less than twenty percent foragers carrying pollen. Temperature and humidity also affected flights of bees to some degree, and bee activities showed similar patterns on different days. However, the activities had diverse characteristics in some time. Though a less number of plants were in flowering, most of them could be utilized by A. cerana cerana, and colonies could effectively get the food resource by behavior adjustment. In addition, visiting activities of bees on the flowers of main garden plants, such as Camellia japonica, showed obvious rhythm. Increasing the flowering plants with nectar and pollen in winter by scientific management of urban gardens would facilitate the creation of suitable habitats for A. cerana cerana and maintaining the wild population.

  5. Ecological investigations on plant associations in differently disturbed heavy-metal contaminated soils of Great Britain

    Ernst, W

    1968-01-01

    In different areas of Great Britain comparing ecological studies have been made on disturbed and undisturbed heavy metal contaminated soils. In Grizedale (Pennine), sampling of an undisturbed transect having high levels of major nutrients showed marked differentiation within a small area, only related to the plant available levels of zinc, copper, and lead. However, studies on disturbed heavy metal soils and spoil-heaps revealed a low water capacity and a low supply of major nutrients, particularly of N and P. These suggest that here both the enrichment of heavy metals and the considerable decrease of other nutrients are important in determining the heavy metal vegetation, and in maintaining it against other species. The quantity of zinc in plants is not related to the total or plant-available amount of zinc in soil, but confirmed physiological experiments on the influence of phosphorus and different zinc compounds (complexed or inorganic) on the uptake and distribution of zinc in Thlaspi alpestre and Minnartia rerum. Also an antagonism between lead and copper was revealed. 24 references.

The citizens of Fukushima feel that the present conditions do not come outside a prefecture and have dissatisfaction for media. A gap occurs in what media convey and thinking that inhabitants want you to tell. One of the causes is a news value point of reference. The other is that the news is carried out in a viewpoint of Tokyo. Is there not the cancellation method? I consider it from the viewpoint of a reporter living in Fukushima city. (author)

    As leaders calling for the conservation of the world's plants, botanical gardens protect plants within living collections. Many also study, manage and restore plants in natural habitats. Royal Botanical Gardens (Ontario,Canada) has integrated both horticultural and natural heritage in its mission for decades. Envisioned by municipal leaders in the 1920s as a combination of nature sanctuaries and civic gardens, RBG now includes forests, wetlands and other habitats, gardens and built spaces. Today RBG is Canada's largest botanical garden on the basis of area.In the 1950s RBG began to inventory plant diversity. The checklist of spontaneous vascular plants now exceeds 1 170 species, of which 752 are native. This is 37% of Ontario's native vascular plants and 19% of the native vascular flora of Canada. The RBG nature sanctuaries are among the richest locations in Canada for species-level diversity.We examine the history of fioristic exploration within RBG and compare plant species-area relationships among protected natural areas in Ontario. This comparison supports the contention that the nature sanctuaries, and in particular Cootes Paradise, could be considered an important area for plants in Canada, and relative to the nation's flora, a biodiversity hotspot. The fact that a candidate vascular plant hotspot for Canada lies within a major botanical garden presents opportunities for raising public awareness of the importance of plant diversity, as well as focusing attention on the scientific and conservation biology needs of communities and individual species in this area.

The current study aimed to gain insight in implementation practices of school gardens and in perceptions of key members and children towards a school garden. We conducted twelve interviews involving 14 key members and five focus groups with 38 children from fifth to sixth grade (10–13 years old in four primary schools in Ghent (Flanders, Belgium. We analyzed the interviews and focus groups in NVivo, using thematic analysis. School gardens were mainly initiated to involve children in nature, not to improve vegetable consumption. Participants were positive about having a school garden, experienced facilitating factors (e.g., adaptability of the garden, having a person responsible for the garden, but also various barriers (e.g., difficulties with startup, maintenance during summer holidays and integration in the school curriculum and suggested some solutions (e.g., involving external organizations and parents, expanding the garden and motivating factors for children (e.g., colorful plants, use of gloves. In order to improve implementation and to contribute to children’s health, future school gardening projects should take the recommendations of key members and children into account.

    School gardening programmes are among the most promising interventions to improve children's vegetable intake. Yet, low vegetable intake among children remains a persistent public health challenge. This study aimed to explore children's perspectives, experiences, and motivations concerning school gardening in order to better understand and increase its potential for health promotion. Using participant observation and semi-structured interviews, we provided 45 primary schoolchildren (9-10 years) from Amsterdam, who participated in a comprehensive year-round school gardening programme, the opportunity to share their experiences and ideas on school gardening. Children particularly expressed enjoyment of the outdoor gardening portion of the programme as it enabled them to be physically active and independently nurture their gardens. Harvesting was the children's favourite activity, followed by planting and sowing. In contrast, insufficient gardening time and long explanations or instructions were especially disliked. Experiencing fun and enjoyment appeared to play a vital role in children's motivation to actively participate. Children's suggestions for programme improvements included more autonomy and opportunities for experimentation, and competition elements to increase fun and variety. Our results indicate that gaining insight into children's perspectives allows matching school gardening programmes more to children's wishes and expectations, thereby potentially enhancing their intrinsic motivation for gardening and vegetable consumption.

  1. Cultivating the Glocal Garden

    2016-04-01

    Full Text Available This paper addresses the question under which conditions small-scale urban agriculture (UA initiatives can accelerate a sustainability transition of the global food system. It develops the notion of a glocal garden, a large number of likeminded local initiatives with a global impact and forms of worldwide collaboration. Taking a transition perspective, the glocal garden, producing vegetables and fruits, is a niche that has to overcome barriers to compete with the dominant food regime. Since a sustainability transition restructures (policy sectors, institutional domains including knowledge systems, the paper explores which innovations are needed for the glocal garden to succeed. It discusses the glocal garden as an environmental, a social, an economic and a global project. As an environmental project, the glocal garden will link sustainable production of food with renewable energy production. As a social project, it will be organized into a consumers’ cooperative. As an economic project, it will strive for profit, increasing the yield in a sustainable manner. As a global project, it will enhance collaboration between local cooperatives in the North and the South, as well as with rural agriculture. Under these conditions, the glocal garden can develop into a power, able to resist a possible future food regime that splits societies, in terms of quality standards and food products, into haves and have-nots.

  4. Writing Gardens - Gardening Drawings: Fung, Brunier and Garening as a model of Landscape Architectural Practice

    Directory of Open Access Journals (Sweden)

    Julian Raxworthy

    2004-06-01

    Full Text Available Landscape architecture is different from other design discourses, notably architecture, because of its utilisation of' dynamic' construction media such as plant materials, soils and water, compared with the 'static' materials of architecture, colloquially described as bricks and mortar. This dynamism refers to the fact that landscape materials not only change, but get better over time. While this is a material difference, its implications extend to practice, which has been modelled, from architecture, to favour a static mode of representation: the drawing. While the drawing is important for the propositional nature of landscape architecture, it may be valuable to look at other disciplines, allied to landscape architecture, which might be seen as better able to engage with change. In this essay, the garden provides just such an example. In the writings of Stanislaus Fung on the Chinese garden text the Yuan vi, an argument is made about writing being a fundamental act in the endeavour of gardening that may offer a bridge across the 'ontological disparity' that exists between representation and the subject, the landscape. To speak of writing in this context suggests that writing about gardens is actually a type of gardening in itself. This argument is extended in the current essay quickly to see if it is also appropriate to consider drawings in this way. This essay also attempts to legitimate theoretically the real possibility of modifying landscape architectural practices to engage with change, by suggesting what might be learned from gardening. In further research by this author, this argument will be used as the theoretical basis for critiquing gardens in such a way that lessons learnt from garden designers can be valuably incorporated back into the discourse of landscape architecture.

    The eastern migratory monarch butterfly (Danaus plexippus L.) population in North America hit record low numbers during the 2013-2014 overwintering season, prompting pleas by scientists and conservation groups to plant the butterfly's milkweed host plants (Asclepias spp.) in residential areas. While planting butterfly gardens with host plants seems like an intuitive action, no previous study has directly compared larval survival in gardens and natural areas to demonstrate that gardens are suitable habitats for Lepidoptera. In this study, milkweed was planted in residential gardens and natural areas. In 2009 and 2010, plants were monitored for oviposition by monarch butterflies and survival of monarch eggs and caterpillars. Monarchs oviposited significantly more frequently in gardens than in natural sites, with 2.0 and 6.2 times more eggs per plant per observation in 2009 and 2010, respectively. There were no significant differences in overall subadult survival between gardens and natural areas. Significant differences in survival were measured for egg and larval cohorts when analyzed separately, but these were not consistent between years. These results suggest that planting gardens with suitable larval host plants can be an effective tool for restoring habitat for monarch butterflies. If planted over a large area, garden plantings may be useful as a partial mitigation for dramatic loss of monarch habitat in agricultural settings. © The Authors 2015.

    2014-03-01

    Community garden research has focused on social aspects of gardens, neglecting systematic analysis of what food is grown. Yet agrodiversity within community gardens may provide health benefits. Diverse fruit and vegetables provide nutritional benefits, including vitamins, minerals and phytochemicals. This paper reports research that investigated the agro-biodiversity of school-based community gardens in Brisbane and Gold Coast cities, Australia. Common motivations for establishing these gardens were education, health and environmental sustainability. The 23 gardens assessed contained 234 food plants, ranging from 7 to 132 plant types per garden. This included 142 fruits and vegetables. The nutritional diversity of fruits and vegetable plants was examined through a color classification system. All gardens grew fruits and vegetables from at least four food color groups, and 75% of the gardens grew plants from all seven color groups. As places with high agrodiversity, and related nutritional diversity, some school community gardens can provide children with exposure to a healthy range of fruit and vegetables, with potential flow-on health benefits.

    This study evaluated adapted gardening as an activity for people with advanced Huntington's disease (HD) and explored its therapeutic aspects. Visitors and staff completed a questionnaire and participated in structured interviews to capture further information, whereas a pictorial questionnaire was designed for residents with communication difficulties. Staff reported that gardening was a constructive, outdoor activity that promoted social interaction, physical activity including functional movement and posed cognitive challenges. Half the staff thought the activity was problem free and a third used the garden for therapy. Visitors used the garden to meet with residents socially. Despite their disabilities, HD clients enjoyed growing flourishing flowers and vegetables, labelling plants, being outside in the sun and the quiet of the garden. The garden is valued by all three groups. The study demonstrates the adapted method of gardening is a stimulating and enjoyable activity for people with advanced HD. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  14. Modification of a Community Garden to Attract Native Bee Pollinators in Urban San Luis Obispo, California

    2009-01-01

    Full Text Available Gardens have become increasingly important places for growing nutritional food, for conserving biodiversity, for biological and ecological research and education, and for community gathering. Gardens can also be designed with the goal of attracting specific wildlife, like birds and butterflies, but pollinators, like bees, can also be drawn to specially planned and modified gardens. A community garden in San Luis Obispo, California provided the setting for modification with the goal of attracting native bee pollinators by planting known bee-attractive plants. The local gardeners participated in a survey questionnaire and focused interviews to provide their input and interest in such a project. Presentations on our work with native bees in urban environments and gardening to attract bees were also given to interested gardeners. Work of this type also benefited from a lead gardener who managed donated bee plants and kept up momentum of the project. Modification of the garden and monitoring of native bees started in 2007 and continued through the growing season of 2009. Diversity of collected and observed native bees has increased each year since 2007. To date, 40 species in 17 genera of mostly native bees has been recorded from the garden, and this number is expected to increase through time.

    Full Text Available Urban gardens have been observed to multiply in response to crises. However, the meaning and motivations behind the emergence of gardening movements varies greatly over space and time. In this paper we argue that bottom up urban gardening initiatives taking place in Southern European countries in form of land occupation and communalization represent forms of resistance that enhance social cohesion and collective action in times of need. Specifically, this research examines the role of urban gardens in (i building community resilience and (ii articulating forms of resistance and contestation to development pressure and commodified urban lifestyles. Our research is based on data collected among 27 urban gardening initiatives in Barcelona, Spain, including 13 self-governed community gardens and 14 public gardens. Data were collected from semi-structured interviews with gardeners and with staff from the Barcelona City Council. Our results show mechanisms through which urban gardens can contribute to build resilience by nurturing social and ecological diversity, generating and transmitting local ecological knowledge, and by creating opportunities for collective action and self-organization. We further examine collectively managed gardens as urban commons that emerge as a form of resistance to the privatization of public urban space, and that offer opportunities to experiment with new models of urban lifestyles. We show how gardening initiatives can be seen to represent an emerging form of urban green commons that provides a suitable ground to ‘sow’ resilience and contestation in times of crises and socio-ecological deterioration.

  16. Botanic gardens should lead the way to create a “Garden Earth” in the Anthropocene

    Directory of Open Access Journals (Sweden)

    Charles H. Cannon

    2017-12-01

    Full Text Available The strength and expertise that botanic gardens bring to conservation are based on their detailed knowledge and understanding of the care, management, and biology of a diversity of plant species. This emphasis on the organism has led to many ex-situ and in-situ conservation programs aimed at protecting endangered species, restoring threatened populations, and establishing living plant and seed collections of endangered species. In China, the scale and pace of change in land and resource use, often leading to environmental degradation, has created a strong emphasis on improving environmental conditions. If done properly, being “green” can be a surprisingly complex issue, because it should encompass and exploit the whole of plant diversity and function. Unfortunately, ‘green’ often includes a small portion of this whole. Earth's rich plant diversity presents considerable opportunity but requires expertise and knowledge for stable and beneficial management. With the dawning of the Anthropocene, we should strive to live on a “Garden Earth”, where we design and manage our environments, both built and natural, to create a healthy, beneficial living landscape for people and other organisms. The staff of botanic gardens worldwide and the living collections they maintain embody the best examples of sustainable, beautiful, and beneficial environments that thrive on plant diversity. This expertise should be a fundamental resource for agencies in all sectors responsible for managing and designing “green” infrastructure. Botanic gardens should actively engage and contribute to these opportunities, from large public infrastructure projects to small private conservation efforts. Here, we discuss several ongoing conservation efforts, primarily in China, and attempt to identify areas where botanic gardens could make a significant and meaningful difference.

    Full Text Available The aim of the studies was to determine the effects of media with composts, based on sewage sludge and potato pulp, on the growth and conformation of the cultivar 'Butterfl y Yellow with Blotch'. In the experiment 14 potting media, including 12 media made of 4 composts, were tested. The percentage of compost mixed with sphagnum peat was 25%, 50% and 75%. The components of particular composts were as follows: I - municipal sewage sludge 70% and straw 30%; II - municipal sewage sludge 70% and sawdust 30%; III - municipal sewage sludge 35%, potato pulp 35% and straw 30%; IV - municipal sewage sludge 35%, potato pulp 35% and sawdust 30%. Two control potting media were used: 1 - sphagnum peat with Osmocote Exact Lo-Start at the dose 5 g×dm-3, and 2 - sphagnum peat with Azofoska at the dose 2.5 g×dm-3. There was no top-dressing during cultivation. The potting media used for pansy cultivation were rich in essential nutrients and in certain media macroelement content exceeded the limits recommended for the species with great nutrient requirements. The effects of the media on the growth, conformation and foliage of pansies depended on compost composition and its pecentage in a medium. The composts used for the media were found to be suitable for pansy cultivation. Despite smaller leaf rosettes in comparison with control plants, the pansies from compost media grew well and showed no disease symptoms.

  3. Untranslated regions of diverse plant viral RNAs vary greatly in translation enhancement efficiency

    2012-05-01

    Full Text Available Abstract Background Whole plants or plant cell cultures can serve as low cost bioreactors to produce massive amounts of a specific protein for pharmacological or industrial use. To maximize protein expression, translation of mRNA must be optimized. Many plant viral RNAs harbor extremely efficient translation enhancers. However, few of these different translation elements have been compared side-by-side. Thus, it is unclear which are the most efficient translation enhancers. Here, we compare the effects of untranslated regions (UTRs containing translation elements from six plant viruses on translation in wheat germ extract and in monocotyledenous and dicotyledenous plant cells. Results The highest expressing uncapped mRNAs contained viral UTRs harboring Barley yellow dwarf virus (BYDV-like cap-independent translation elements (BTEs. The BYDV BTE conferred the most efficient translation of a luciferase reporter in wheat germ extract and oat protoplasts, while uncapped mRNA containing the BTE from Tobacco necrosis virus-D translated most efficiently in tobacco cells. Capped mRNA containing the Tobacco mosaic virus omega sequence was the most efficient mRNA in tobacco cells. UTRs from Satellite tobacco necrosis virus, Tomato bushy stunt virus, and Crucifer-infecting tobamovirus (crTMV did not stimulate translation efficiently. mRNA with the crTMV 5′ UTR was unstable in tobacco protoplasts. Conclusions BTEs confer the highest levels of translation of uncapped mRNAs in vitro and in vivo, while the capped omega sequence is most efficient in tobacco cells. These results provide a basis for understanding mechanisms of translation enhancement, and for maximizing protein synthesis in cell-free systems, transgenic plants, or in viral expression vectors.

    2017-04-01

    In agroecosystems, local and landscape features, as well as natural enemy abundance and richness, are significant predictors of predation services that may result in biological control of pests. Despite the increasing importance of urban gardening for provisioning of food to urban populations, most urban gardeners suffer from high pest problems, and have little knowledge about how to manage their plots to increase biological control services. We examined the influence of local, garden scale (i.e., herbaceous and arboreal vegetation abundance and diversity, ground cover) and landscape (i.e., landscape diversity and surrounding land use types) characteristics on predation services provided by naturally occurring predators in 19 urban gardens in the California central coast. We introduced sentinel pests (moth eggs and larvae and pea aphids) onto greenhouse-raised plants taken to gardens and assigned to open or bagged (predator exclosure) treatments. We found high predation rates with between 40% and 90% of prey items removed in open treatments. Predation services varied with local and landscape factors, but significant predictors differed by prey species. Predation of eggs and aphids increased with vegetation complexity in gardens, but larvae predation declined with vegetation complexity. Smaller gardens experienced higher predation services, likely due to increases in predator abundance in smaller gardens. Several ground cover features influenced predation services. In contrast to patterns in rural agricultural landscapes, predation on aphids declined with increases in landscape diversity. In sum, we report the relationships between several local management factors, as well as landscape surroundings, and implications for garden management. © 2017 by the Ecological Society of America.

    Full Text Available With an ever-increasing urban population, promoting public health and well-being in towns and cities is a major challenge. Previous research has suggested that participating in allotment gardening delivers a wide range of health benefits. However, evidence from quantitative analyses is still scarce. Here, we quantify the effects, if any, of participating in allotment gardening on physical, psychological and social health. A questionnaire survey of 332 people was performed in Tokyo, Japan. We compared five self-reported health outcomes between allotment gardeners and non-gardener controls: perceived general health, subjective health complaints, body mass index (BMI, mental health and social cohesion. Accounting for socio-demographic and lifestyle variables, regression models revealed that allotment gardeners, compared to non-gardeners, reported better perceived general health, subjective health complaints, mental health and social cohesion. BMI did not differ between gardeners and non-gardeners. Neither frequency nor duration of gardening significantly influenced reported health outcomes. Our results highlight that regular gardening on allotment sites is associated with improved physical, psychological and social health. With the recent escalation in the prevalence of chronic diseases, and associated healthcare costs, this study has a major implication for policy, as it suggests that urban allotments have great potential for preventative healthcare.

    The natural gas purification and pipeline sector is a major economic driver in Canada. Gas processing facilities are growing in number, and several large gas projects are being planned for future construction in the western provinces. This article outlined 5 gas plants in order to illustrate the sector's history and breadth in Canada. The Shell Jumping Pound gas complex was constructed in 1951 after a sulfur-rich gas discovery near Calgary in 1944. The Empress Straddle plant was built in 1971 in southeastern Alberta and is one of the largest single industrial consumers of electrical power in the province. The Fort Nelson gas processing plant is North America's largest sour gas processing facility. The Shell Caroline complex was built 1993. The Sable offshore energy project is located on the coast of Nova Scotia to handle gas produced from the Thebaud wells. A consortium is now considering the development of new gas fields in the Sable area. 5 figs.

    phytopathology in Poland, Head of the Department of Botany II (Agricultural Botany, renamed in 1926 as the Department of Plant Taxonomy, and in 1937 – the Department of Taxonomy and Geography of Plants. From May 1937 to 1939, his successor as director was Franciszek Ksawery Skupieński (1888–1962, a researcher of slime moulds. Great credit for the development of the Garden is due to the Inspector, i.e. Chief Gardener, Konstanty Prószyński (Proszyński (1859–1936 working there from 1919, through his official nomination in 1920, until his death. He was an amateur-naturalist, a former landowner, who had lost his property. Apart from the work on establishing and maintaining the Garden’s collection, as well as readying seeds for exchange, he published one mycological paper, and prepared a manuscript on fungi, illustrated by himself, containing descriptions of the new species. Unfortunately, this work was not published for lack of funds, and the prepared material was scattered. Some other illustrations of flowering plants drawn by Prószyński survived. There were some obstacles to the further development of the institution, namely substantially inadequate funds as well as too few members of the personnel (1–3 gardeners, and 1–3 seasonal workers. The area of the Garden, covering approx. 2 hectares was situated on the left bank of the Neris river (Polish: Wilia. It was located on sandy soils of a floodplain, and thus liable to flooding. These were the reasons for the decision taken in June 1939 to move the Garden to a new site but the outbreak of the Second World War stood in the way. Despite these disadvantageous conditions, the management succeeded in setting up sections of plants analogous to these established in other botanical gardens in Poland and throughout the world, i.e. general taxonomy (1922, native flora (1922, psammophilous plants (1922, cultivated plants (1924/1925, plant ecology (1927/1928, alpinarium (1927–1929, high-bog plants (1927–1929, and

  16. Great genetic differentiation among populations of Meconopsis integrifolia and its implication for plant speciation in the Qinghai-Tibetan Plateau.

    Directory of Open Access Journals (Sweden)

    Fu-Sheng Yang

    Full Text Available The complex tectonic events and climatic oscillations in the Qinghai-Tibetan Plateau (QTP, the largest and highest plateau in the world, are thought to have had great effects on the evolutionary history of the native plants. Of great interest is to investigate plant population genetic divergence in the QTP and its correlation with the geologic and climatic changes. We conducted a range-wide phylogeographical analysis of M. integrifolia based on the chloroplast DNA (cpDNA trnL-trnF and trnfM-trnS regions, and defined 26 haplotypes that were phylogenetically divided into six clades dated to the late Tertiary. The six clades correspond, respectively, to highly differentiated population groups that do not overlap in geographic distribution, implying that the mountain ranges acting as corridors or barriers greatly affected the evolutionary history of the QTP plants. The older clade of M. integrifolia only occurs in the southwest of the species' range, whereas the distributions of younger clades extend northeastward in the eastern QTP, suggesting that climatic divergence resulting from the uplift of the QTP triggered the initial divergence of M. integrifolia native to the plateau. Also, the nrDNA ITS region was used to clarify the unexpected phylogenetic relationships of cpDNA haplotypes between M. integrifolia and M. betonicifolia. The topological incongruence between the two phylogenies suggests an ancestral hybridization between the two species. Our study indicates that geographic isolation and hybridization are two important mechanisms responsible for the population differentiation and speciation of Meconopsis, a species-rich genus with complex polyploids.

    The Climate Museum and Garden is conceived as a cross-disciplinary experience, where the arts and sciences link together to increase understanding of the Earth's climate and its relevance to our fate as a species. This would be a place of inspiration. The Climate Museum and Garden would merge concepts of modern art museums and modern science museums, with exhibitions, live music and theater performances, visitor interaction, unique discoveries and reflection. It would be a place where visitors are immersed in experiences, lingering indoors and out in quiet consideration and gratitude for our planet's atmosphere. The story of climate change is compelling in its own right; theories of the greenhouse effect go back over century and climate policy has stretched back a few decades. Whereas scientific researchers have been contributing to understanding the mechanisms and impacts of climate change for many decades; whereas researchers have participated in climate summits and informed policy makers; whereas researchers have taught classes of gifted students; in all of this, the public has mostly missed out. This public relations gap has been unfortunately filled by those that would seek to politicize and mislead the public, leading to an engagement gap among the general public. Now we stand on a precipice. Therefore we see a ripe opportunity to reach out and inspire the population. We build off of current pedagogic research that shows that experienced-based learning is more impactful when it engages the senses and elicits an emotional response. People understand what they experience, what they feel, and this serves as the basis for personal reflection. In this sense the visitor experience is generative, in that it promotes further personal investigation and interaction. The Climate Museum and Garden would be a start. In the future, we envisage a future network of climate museums in all major cities. It would be a flagship attraction for any city, along with their art

    2011-01-01

    The Great East Japan Earthquake occurred in March 11, 2011 brought about severe accident at nuclear power plant, which gave significant lessons to nuclear experts concerned with safety measures. Concepts of defence in depth was basic philosophy to assure safety of nuclear power plant even against uncertainties exceeding design basis. This concept consisted of prevention, monitoring, and action to mitigate consequences of failures such as a series of physical barriers between the reactor core and the environment, which were called multiple safety systems, each with backup and designed to accommodate human error. As for natural disaster, depth of recognition of characteristic of natural phenomena and its effect and engineering judgment was of prime importance. Different waveforms of ground motion at Fukushima and Onagawa at the Great East Japan Earthquake showed that design ground motion should have large uncertainties. To cope with uncertainties of ground motion, robust seismic measures based on experience were such as design of static seismic intensity and rigid structure of natural period less than 0.1 sec. As for tsunami, defence in depth measures were prepared for the cooling of reactor core, spent fuel and related electric generation equipment with taking into account 1) time lag between tsunami generation and arrival, 2) tsunami affected area could be limited by coastal levee or anti-inundation measure, 3) system redundancy could be assured by different locations of equipments and 4) repair works could be done by shipment of replacement equipment from outside due to limitation of affected regional area. Success examples of Onagawa, Tokai unit 2, Fukushima Daiichi unit 6 and Fukushima Daini Nuclear Power Plants could suggest definite tsunami defence in depth measures. Containment vent system as final heat sink and emergency condenser as reactor core cooling at outage should be properly utilized for Fukushima Daiichi unit 1 Nuclear Power Plant. (T. Tanaka)

    The title subject is described mainly from the pediatric aspect. Shortly after the Quake (Mar. 11, 2011), Disaster Medical Assistance Team (DMAT) and Japan Medical Association Team (JMAT) started on their disaster emergent activity with various personnel and students of Fukushima Medical University (FMU). The Power Plant Accident broke out on the next day, and FMU was the base in charge of multiple managements of radiological medicare as well as the ordinary emergent one. Number of children emergently admitted in or requiring the general pediatric consultation was rather small, and problems of insufficient pediatric articles were virtually solved within 2 weeks. Pediatric support by FMU was done from April to May end for children in evacuation places. At 3 months after the disaster, the birth number markedly decreased near the Plant, and pediatric in- and out-patient number also diminished in the whole Fukushima prefecture, suggesting that many at pregnancy or having infants had evacuated out of the prefecture probably because of their concern of possible radiation health hazard. In consideration of epidemiology of A-bomb survivors and of victims in Chernobyl Accident, so much increased prevalence of pediatric thyroid cancer is conceived to be hardly observed after Fukushima Accident. The project of Fukushima Health Management Survey involves fundamental and detailed examinations. The former subject is to all of prefectural residents who lived at the time of the Quake and the latter, to all children's thyroid with the age <18 y by ultrasonographic follow-up, to all residents dwelled in the evacuation areas by the detailed physical and mental/life-style examinations and to pregnant women by questionnaire and follow-up. Residents' concern is mostly toward the health of infants who are sensitive to radiation. (T.T.)

  2. The Role of the Senses in the Early Modern Italian Garden

    DEFF Research Database (Denmark)

    Knudsen, Karin Esmann

    According to the Italian humanists gardens can be regarded as a third nature (John Dixon Hunt: Greater Perfections 2000, Claudia Lazzaro: The Italian Renaissance Garden 1990). Different from the first nature, wilderness, and the second nature, the cultural landscape (Cicero) gardens are a special...... combination of nature and culture, more sophisticated, more deliberate, more complex in the mixture of culture and nature. In the Italian renaissance garden this third nature reached an artificial and aesthetic level as a pleasure garden which made use of all the senses, and in doing so it played an important...... role in constructing new conceptions of the connection between man and nature. This presentation will examine how the gardens around Italian Renaissance villas in Tuscany and in the surroundings of Rome, with their use of geometrical lay-out, water, sounds, views, plants and buildings not only...

    Few studies have examined the health-related consequences of gardening among older adults. This scoping review summarizes and characterizes current research that examines the relationship between physical health and participation in planned gardening activities, including establishing, maintaining, or caring for plants. Six databases were searched. Eligible studies were published between 2000 and 2013, were published in English, and assessed different aspects of physical health (e.g., functional ability, energy expenditure, injury) for older adults who had participated in a planned gardening activity. Of the eight eligible studies identified with these criteria, four assessed energy expenditures and four assessed physical functioning. Studies assessing energy expenditures documented that the majority of gardening tasks were classified into low-to-moderate intensity physical activity. The current literature does not provide sufficient evidence of the physical functioning consequences of gardening. Future studies should consider how specific gardening interventions help older adults meet physical activity guidelines. © The Author(s) 2014.

    Stormwater runoff in urban areas is increasingly being managed by means of a variety of treaments that reduce or delay runoff and promote more natural infiltration. One such treatment is a rain garden, which is built to detain runoff and allow for water infiltration and uptake by plants.Water flow into or out of a rain garden can be readily monitored with a variety of tools; however, observing the movement of water within the rain garden is less straightforward. Soil-moisture probes in combination with an automated interpolation procedure were used to document the infiltration of water into two rain gardens in Ohio. Animations show changes in soil moisture in the rain gardens during two precipitation events. At both sites, the animations demonstrate underutilization of the rain gardens.

    With rapid urban and economic development, living standard improves in urban areas but urban ecological environments deteriorate rapidly. Urban waterlogging and flooding have become a serious problem for urban water security. As urbanization continues, sustainability is the key to balance between urban development and healthy environment. Rain garden is recommended to be one of the best ways to reduce urban pollutants. It not only diminishes runoff flooding but also purify water in the urban area. The studies on rain gardens are mainly about how to incorporate rain garden to purify water quality, but lack of researches on runoff control. This project focuses on rain garden under Low Impact Development using indoor laboratory to test and quantify the water holding capacities of two different Taiwan indigenous rain garden plants, Taiwan Cyclosorus and Sour Grass. The results show that the water holding capacity of Sour Grass (10%-37%) is better than that of Taiwan Cyclosorus (6.8%-17.3%). The results could be a helpful reference for Low Impact Development in urban flood prevention and urban planning.

    Urban dwellers across the United States increasingly access a variety of fresh vegetables through participation in neighborhood-level community gardens. Here we document vegetable output and cost savings of community gardens in the city of San Jose, CA, to better understand the capacity of community gardens to affect food affordability in an urban setting. A convenience sample of 83 community gardeners in San Jose completed a background survey during spring and summer 2012. On average, gardeners were aged 57 years and had a monthly income of $4,900; 25% had completed college. A representative subset of 10 gardeners was recruited to weigh vegetable output of their plots using portable electronic scales at three separate garden sites. Accuracy of each portable scale was verified by comparing the weight of a sample vegetable to weights obtained using a lab scale precise to 0.2 oz. Garden yields and cost savings were tabulated overall for each plot. Results indicate that community garden practices are more similar to biointensive high-production farming, producing 0.75 lb vegetables/sq ft, rather than conventional agricultural practices, producing 0.60 lb/sq ft. Gardens produced on average 2.55 lb/plant and saved $435 per plot for the season. Results indicate that cost savings are greatest if vertical high value crops such as tomatoes and peppers are grown in community gardens, although yields depend on growing conditions, gardener's skill, availability of water, and other factors. Future research is needed to document cost savings and yields for specific crops grown in community gardens. Copyright © 2014 Academy of Nutrition and Dietetics. Published by Elsevier Inc.

  9. Adapting the botanical landscape of Melbourne Gardens (Royal Botanic Gardens Victoria in response to climate change

    2017-12-01

    Full Text Available Botanic gardens around the world maintain collections of living plants for science, conservation, education, beauty and more. These collections change over time – in scope and content – but the predicted impacts of climate change will require a more strategic approach to the succession of plant species and their landscapes. Royal Botanic Gardens Victoria has recently published a ‘Landscape Succession Strategy’ for its Melbourne Gardens, a spectacular botanical landscape established in 1846. The strategy recognizes that with 1.6 million visitors each year, responsibility for a heritage-listed landscape and the need to care for a collection of 8500 plant species of conservation and scientific importance, planting and planning must take into account anticipated changes to rainfall and temperature. The trees we plant today must be suitable for the climate of the twenty-second century. Specifically, the Strategy sets out the steps needed over the next twenty years to transition the botanic garden to one resilient to the climate modelled for 2090. The document includes a range of practical measures and achievable (and at times somewhat aspirational targets. Climate analogues will be used to identify places in Australia and elsewhere with conditions today similar to those predicted for Melbourne in 2090, to help select new species for the collection. Modelling of the natural and cultivated distribution of species will be used to help select suitable growth forms to replace existing species of high value or interest. Improved understanding of temperature gradients within the botanic garden, water holding capacity of soils and plant water use behaviour is already resulting in better targeted planting and irrigation. The goal is to retain a similar diversity of species but transition the collection so that by 2036 at least 75% of the species are suitable for the climate in 2090. Over the next few years we hope to provide 100% of irrigation water

    Perfluoroalkyl acids (PFAAs) are highly persistent substances which have been detected in wildlife around the world, including birds. Although bird eggs have often been used to determine and monitor PFAAs levels in the marine environment, this has rarely been done in the terrestrial environment. In the present study we examined the concentrations and composition profile of 12 PFAAs (4 perfluoroalkyl sulfonic acids (PFSAs) and 8 perfluoroalkyl carboxylic acids (PFCAs) in the eggs of great tits (Parus major) collected at a fluorochemical plant and in three other areas, representing a gradient in distance from the pollution source (from 1 to 70 km), in Antwerp, Belgium. The PFSA concentrations measured at the site of the fluorochemical plant were among the highest ever reported in eggs with median concentrations of 10380 ng/g (extrapolated), 99.3 ng/g and 47.7 ng/g for PFOS, PFHxS and PFDS respectively. Furthermore, the median concentration of 19.8 ng/g for PFOA was also among the highest ever reported in bird eggs. Although these concentrations decreased sharply with distance from the fluorochemical plant, levels found in the adjacent sites were still high compared to what has been reported in literature. Moreover, based on what is known in literature, it is likely that these concentrations may cause toxicological effects. PFOS was the dominant contributor to the PFSA and PFAAs (63.4-97.6%) profile at each site, whereas for PFCAs this was PFOA at the plant site and the nearest locations (41.0-52.8%) but PFDoA (37.7%) at the farthest location. Although there is some evidence that PFAAs concentrations close to the plant site are decreasing in comparison with earlier measurements, which may be due to the phase out of PFOS, more research is necessary to understand the extent of the toxicological effects in the vicinity of this PFAAs hotspot.

The level of weed biomass did not vary greatly across mixtures varying widely in proportions of sown species. These diversity benefits in intensively managed grasslands are relevant for the sustainable intensification of agriculture and, importantly, are achievable through practical farm-scale actions.

    2004-01-01

    Objectives were to review the literature on horticultural therapy and describe the Danderyd Hospital Horticultural Therapy Garden and its associated horticultural therapy programme. The literature review is based on the search words 'gardening', 'healing garden' and 'horticultural therapy'. The description is based on the second author's personal knowledge and popular-scientific articles initiated by her. The material has been integrated with acknowledged occupational therapy literature. The setting was the Danderyd Hospital Rehabilitation Clinic, Sweden, Horticultural Therapy Garden. Forty-six patients with brain damage participated in group horticultural therapy. Horticulture therapy included the following forms: imagining nature, viewing nature, visiting a hospital healing garden and, most important, actual gardening. It was expected to influence healing, alleviate stress, increase well-being and promote participation in social life and re-employment for people with mental or physical illness. The Horticultural Therapy Garden was described regarding the design of the outdoor environment, adaptations of garden tools, cultivation methods and plant material. This therapy programme for mediating mental healing, recreation, social interaction, sensory stimulation, cognitive re-organization and training of sensory motor function is outlined and pre-vocational skills and the teaching of ergonomical body positions are assessed. This study gives a broad historic survey and a systematic description of horticultural therapy with emphasis on its use in rehabilitation following brain damage. Horticulture therapy mediates emotional, cognitive and/or sensory motor functional improvement, increased social participation, health, well-being and life satisfaction. However, the effectiveness, especially of the interacting and acting forms, needs investigation.

  14. Phylogenetic relationships in Epidendroideae (Orchidaceae), one of the great flowering plant radiations: progressive specialization and diversification.

    2015-03-01

    The largest subfamily of orchids, Epidendroideae, represents one of the most significant diversifications among flowering plants in terms of pollination strategy, vegetative adaptation and number of species. Although many groups in the subfamily have been resolved, significant relationships in the tree remain unclear, limiting conclusions about diversification and creating uncertainty in the classification. This study brings together DNA sequences from nuclear, plastid and mitochrondrial genomes in order to clarify relationships, to test associations of key characters with diversification and to improve the classification. Sequences from seven loci were concatenated in a supermatrix analysis for 312 genera representing most of epidendroid diversity. Maximum-likelihood and parsimony analyses were performed on this matrix and on subsets of the data to generate trees and to investigate the effect of missing values. Statistical character-associated diversification analyses were performed. Likelihood and parsimony analyses yielded highly resolved trees that are in strong agreement and show significant support for many key clades. Many previously proposed relationships among tribes and subtribes are supported, and some new relationships are revealed. Analyses of subsets of the data suggest that the relatively high number of missing data for the full analysis is not problematic. Diversification analyses show that epiphytism is most strongly associated with diversification among epidendroids, followed by expansion into the New World and anther characters that are involved with pollinator specificity, namely early anther inflexion, cellular pollinium stalks and the superposed pollinium arrangement. All tested characters show significant association with speciation in Epidendroideae, suggesting that no single character accounts for the success of this group. Rather, it appears that a succession of key features appeared that have contributed to diversification, sometimes in

  15. Plant Species Rather Than Climate Greatly Alters the Temporal Pattern of Litter Chemical Composition During Long-Term Decomposition

    A feedback between decomposition and litter chemical composition occurs with decomposition altering composition that in turn influences the decomposition rate. Elucidating the temporal pattern of chemical composition is vital to understand this feedback, but the effects of plant species and climate on chemical changes remain poorly understood, especially over multiple years. In a 10-year decomposition experiment with litter of four species (Acer saccharum, Drypetes glauca, Pinus resinosa, and Thuja plicata) from four sites that range from the arctic to tropics, we determined the abundance of 11 litter chemical constituents that were grouped into waxes, carbohydrates, lignin/tannins, and proteins/peptides using advanced 13C solid-state NMR techniques. Decomposition generally led to an enrichment of waxes and a depletion of carbohydrates, whereas the changes of other chemical constituents were inconsistent. Inconsistent convergence in chemical compositions during decomposition was observed among different litter species across a range of site conditions, whereas one litter species converged under different climate conditions. Our data clearly demonstrate that plant species rather than climate greatly alters the temporal pattern of litter chemical composition, suggesting the decomposition-chemistry feedback varies among different plant species.

    Cancer survivors are at increased risk for second malignancies, cardiovascular disease, diabetes, and functional decline. Evidence suggests that a healthful diet and physical activity may reduce the risk of chronic disease and improve health in this population. We conducted a feasibility study to evaluate a vegetable gardening intervention that paired 12 adult and child cancer survivors with Master Gardeners to explore effects on fruit and vegetable intake, physical activity, quality-of-life, and physical function. Throughout the year-long study period, the survivor-Master Gardener dyads worked together to plan/plant three gardens, harvest/rotate plantings, and troubleshoot/correct problems. Data on diet, physical activity, and quality-of-life were collected via surveys; anthropometrics and physical function were objectively measured. Acceptability of the intervention was assessed with a structured debriefing survey. The gardening intervention was feasible (robust enrollment; minimal attrition) and well-received by cancer survivors and Master Gardeners. Improvement in three of four objective measures of strength, agility, and endurance was observed in 90% of survivors, with the following change scores [median (interquartile range)] noted between baseline and one-year follow-up: hand grip test [+ 4.8 (3.0, 6.7) kg], 2.44 meter Get-Up-and-Go [+ 1.0 (+ 1.8, + 0.2) seconds], 30-second chair stand [+ 3.0 (+ 1.0, 5.0) stands], and six-minute walk [+ 11.6 (6.1, 48.8) meters]. Increases of ≥ 1 fruit and vegetable serving/day and ≥ 30 minutes/week of physical activity were observed in 40% and 60%, respectively. These preliminary results support the feasibility and acceptability of a mentored gardening intervention and suggest that it may offer a novel and promising strategy to improve fruit and vegetable consumption, physical activity, and physical function in cancer survivors. A larger randomized controlled trial is needed to confirm our results.

    Full Text Available The results of the evaluation of the growth and development rates, the seed productivity, the green mass yield, the biochemical composition and the content of amino acids, phosphorous and calcium, the nutritive and energy value of the forage, as well as the biomethane productivity of local ecotypes of the leguminous species maintained in monoculture, in the collection of the Botanical Garden (Institute of the Academy of Sciences of Moldova (BG ASM: Astragalus ponticus, Coronilla varia, Lotus corniculatus, Medicago falcata, Onobrychis arenaria and Trifolium repens are presented in this article. Control variants – the traditional forage crops: Medicago sativa and Onobrychis viciifolia. The local ecotypes of the studied leguminous species were characterized by different growth and development rates. Coronilla varia and Lotus corniculatus, in the 2nd-3rd years, could be harvested, for the first time, 5 days earlier than Medicago sativa, but Medicago falcata and Onobrychis viciifolia – 18 days later. The green mass yield varied from 0.83 kg/m2 to 4.08 kg/m2. The studied ecotypes reached amounts of 0.60-0.89 nutritive units/kg and metabolizable energy 8.05-9.90 MJ/kg of dry matter, the content of digestible protein, of 106.28-225.09 g/nutritive unit, met the zootechnical standards; seed production: 19.12-83.00 g/m2; the biomethane yield ranged from 692 to 3197 m3/ha. Higher yield of natural forage, dry matter and biomethane was produced by Onobrychis arenaria and Coronilla varia.

  20. Past approaches and future challenges to the management of fire and invasive alien plants in the new Garden Route National Park

    Directory of Open Access Journals (Sweden)

    Richard M. Cowling

    2011-09-01

    Full Text Available The recently established Garden Route National Park (GRNP along the Cape south coast of South Africa occurs in a landscape where indigenous forests, fire-prone fynbos shrublands and fire-sensitive plantations of alien invasive trees are interspersed. We used the area as a case study in the challenges facing conservation managers in the achievement of biodiversity goals in a fire-prone environment. We explored the context within which fire management was practised during the past century by interviewing former catchment managers and reviewing forestry and catchment management policies. Mountain fynbos adjacent to plantations was subjected to burning regimes aimed at the protection of commercial timber resources rather than the preservation of fynbos biodiversity. Prescribed burning of fynbos adjacent to the plantations was typically done in multiple belt systems at rotations of about 4–8 years during spring, summer and autumn, to avoid the winter berg wind season. Such short-rotation and low-intensity fires favour resprouting graminoids over slow-maturing reseeders, and likely account for the compositional impoverishment observed in fynbos near plantations. Current and future challenges faced by the GRNP include (1 balancing conflicting fire management requirements for plantation safety against fynbos conservation; (2 the continual invasion of fynbos by fire-propagated alien pines sourced from plantations; (3 inadequate resources to redress the ‘invasion debt’ caused by the socio-economic legacy and past management neglect; and (4 fragmentation of land use between conservation and forestry threatening the sustainability of the region at large. We provide recommendations for management actions and research priorities to address these challenges.

  1. A multi-case study of school gardens in Southwest Montana

    Yates, Kimberly Ann

    Many children today spend little time outdoors exploring the natural world and a great deal of time inside viewing the television or playing video games. This new condition of childhood has many negative ramifications, such as poor social development, childhood obesity, and a lack of feeling connected to the environment. One instructional tool being used by some schools to address these rising concerns is a school garden. School gardens can provide an opportunity for students to experience learning in a real-world application, outside of the classroom walls. This qualitative multi-case study explores three school gardens in Southwest Montana and tells each of their unique stories. Through the process of participant observation, interviews, and the collection of multiple data sources, a thorough description is given of the history behind the gardens, how they have impacted the teachers and students, what challenges they have faced, and the common characteristics found in a successful school garden program. During the data analysis process, themes for each case study site were revealed. The results of this study found that each school garden was unique in character and purpose and that a number of dedicated garden supporters are essential to the success of a garden program. In conclusion, suggestions and resources were provided for practitioners interested in pursuing a garden program.

  2. Spirituality and Aging in Place: The Impact of Extreme Climatic Conditions on Domestic Gardening Practice.

    Adams, Joanne; Pascal, Jan; Dickson-Swift, Virginia

    2014-12-01

    There is limited research exploring how domestic water restrictions imposed as a result of drought conditions impact upon the lives of independently living older people. Within this age group (60 years plus), the domestic garden frequently forms an intrinsic component of ongoing health and well-being. Gardening practice offers components of both mental and physical activity and, for many older people, leads to emotional and spiritual connection on a number of levels. The capacity of older people to maintain a garden during a period of water restrictions is greatly reduced, and the resulting impact on health and well-being is considerable. A recent study, conducted in south-eastern Australia, aimed to determine the benefits to health and well-being of maintaining a domestic garden for older people and the impact of water restrictions on garden practice. This occurred at a time following a prolonged period of drought and, in central Victoria, a complete ban on outside watering. In-depth qualitative interviews were conducted with 10 gardeners aged between 60 and 83 who had tended their garden over an extended period. The lived experience of gardening was explored through hermeneutic phenomenological analysis. Clear benefits to health and well-being were established, and yet, the essence of this experience lay in the capacity of gardeners to remain connected to their garden despite change. The crisis imposed by ongoing drought and restricted use of water generated a strong impetus for adaptation, resilience and acceptance of change. The spiritual nature of gardening practice clearly emerged and appeared to intensify the experience of gardening and consolidate adaption to change on a number of levels. © The Author(s) 2015.

    Fungus-growing (attine) ants and their fungal symbionts passed through several evolutionary transitions during their 50 million year old evolutionary history. The basal attine lineages often shifted between two main cultivar clades, whereas the derived higher-attine lineages maintained an association with a monophyletic clade of specialized symbionts. In conjunction with the transition to specialized symbionts, the ants advanced in colony size and social complexity. Here we provide a comparative study of the functional specialization in extracellular enzyme activities in fungus gardens across the attine phylogeny. We show that, relative to sister clades, gardens of higher-attine ants have enhanced activity of protein-digesting enzymes, whereas gardens of leaf-cutting ants also have increased activity of starch-digesting enzymes. However, the enzyme activities of lower-attine fungus gardens are targeted primarily toward partial degradation of plant cell walls, reflecting a plesiomorphic state of nondomesticated fungi. The enzyme profiles of the higher-attine and leaf-cutting gardens appear particularly suited to digest fresh plant materials and to access nutrients from live cells without major breakdown of cell walls. The adaptive significance of the lower-attine symbiont shifts remains unclear. One of these shifts was obligate, but digestive advantages remained ambiguous, whereas the other remained facultative despite providing greater digestive efficiency.

    Full Text Available Introduction: The study of symbiotic relationship between arbuscular mycorrhizal fungi (AMF and medicinal plants is very important. Information about the symbiosis of medicinal plant species with AMF in the semi-arid regions of Iran is rare. This information allows increasing knowledge of the biology and ecology of these plant species. Materials and methods: The existence of AM symbiosis in 48 medicinal plant species (belonging to 9 families was studied by root staining. Soil around the root of each species was sampled and analyzed for all soil properties which may be interrelated to AM symbiosis. The importance of different soil properties in AMF and plant biological relationship and the dependency of root colonization and spore formation by AMF on soil properties were statistically analyzed. Results: Among them Lepidium sativum, Brassica oleracea, Cheiranthus cheiri, Beta vulgaris, Spinacia oleracea, Malva sylvestris, Zygophyllum fabago, Arctium Lappa have not been colonized by AM fungi. Colonization and spore density of perennial plants were slightly higher than those of annual plants and were varied among different plant families. Soil texture and available phosphorous were the most important soil properties affecting fungal root colonization and spore numbers. Discussion and conclusion: Although in accordance with other researches, most of the medicinal plants from Brassicaceae family had no mycorrhizal symbiosis, a few of them had this type of symbiosis. Dependency of spore formation by AM fungi on soil properties was higher than dependency of root colonization percentage on soil properties. Increasing root colonization and spore numbers with increasing the percentage of sand and decreasing the percentage of clay and available phosphorous in soils show that plants are more depended on mycorrhizal symbiosis in hard environments and less productive soils.

    School gardening programmes are among the most promising interventions to improve children’s vegetable intake. Yet, low vegetable intake among children remains a persistent public health challenge. This study aimed to explore children’s perspectives, experiences, and motivations concerning school gardening in order to better understand and increase its potential for health promotion. Using participant observation and semi-structured interviews, we provided 45 primary schoolchildren (9–10 years) from Amsterdam, who participated in a comprehensive year-round school gardening programme, the opportunity to share their experiences and ideas on school gardening. Children particularly expressed enjoyment of the outdoor gardening portion of the programme as it enabled them to be physically active and independently nurture their gardens. Harvesting was the children’s favourite activity, followed by planting and sowing. In contrast, insufficient gardening time and long explanations or instructions were especially disliked. Experiencing fun and enjoyment appeared to play a vital role in children’s motivation to actively participate. Children’s suggestions for programme improvements included more autonomy and opportunities for experimentation, and competition elements to increase fun and variety. Our results indicate that gaining insight into children’s perspectives allows matching school gardening programmes more to children’s wishes and expectations, thereby potentially enhancing their intrinsic motivation for gardening and vegetable consumption.

    Correlations between the yield of seedings in green house, survival rate, growth and development in an outdoor plot with rigid agroecological conditions were studied, when variability of these indices was due to γ-irradiation of seeds in different modes. The results obtained allow us to suppose that when a heterogeneous population of garden roses exposed to high doses significantly reduced their germination ability, a selection of ecologically stable, well growing and developing genotypes can take place. It is accounted for direct relation between radioresistance of the seeds and their genetically conditioned ecological stability and ability of seedings to good growth and development

    We assessed options for mitigating greenhouse gas emissions from electricity generation in the US Great Lakes States, a region heavily dependent on coal-fired power plants. A proposed 600 MW power plant in northern Lower Michigan, USA provided context for our evaluation. Options to offset fossil CO 2 emissions by 20% included biomass fuel substitution from (1) forest residuals, (2) short-rotation woody crops, or (3) switchgrass; (4) biologic sequestration in forest plantations; and (5) geologic sequestration using CO 2 capture. Review of timber product output data, land cover data, and expected energy crop productivity on idle agriculture land within 120 km of the plant revealed that biomass from forestry residuals has the potential to offset 6% and from energy crops 27% of the annual fossil fuel requirement. Furthermore, annual forest harvest in the region is only 26% of growth and the surplus represents a large opportunity for forest products and bioenergy applications. We used Life Cycle Assessment (LCA) to compare mitigation options, using fossil energy demand and greenhouse gas emissions per unit electricity generation as criteria. LCA results revealed that co-firing with forestry residuals is the most attractive option and geologic sequestration is the least attractive option, based on the two criteria. Biologic sequestration is intermediate but likely infeasible because of very large land area requirements. Our study revealed that biomass feedstock potentials from land and forest resources are not limiting mitigation activities, but the most practical approach is likely a combination of options that optimize additional social, environmental and economic criteria.

    Residences located within 20 km of the damaged Fukushima Daiichi Nuclear Power Plant were evacuated shortly after the Great East Japan Earthquake. The levels of airborne and surface fungi were measured in six houses in the evacuation zone in August 2012 and February 2013. Airborne fungal levels in all of the houses in the summer were higher than the environmental standard levels for residential houses published in Architectural Institute of Japan (>1000 colony-forming units [CFU]/m 3 ). In two houses whose residents rarely returned to visit, fungal levels were extremely high (>52,000 CFU/m 3 ). Although fungal levels in the winter were much lower than those in the summer, they were still higher than environmental standard levels in several houses. Indoor fungal levels were significantly inversely related to the frequency with which residents returned, but they were not correlated with the air exchange rates, temperature, humidity, or radiation levels. Cladosporium spp. and Penicillium spp. were detected in every house. Aspergillus section Circumdati (Aspergillus ochraceus group) was also detected in several houses. These fungi produced ochratoxin A and ochratoxin B, which have nephrotoxic and carcinogenic potential. The present study suggests that further monitoring of fungal levels is necessary in houses in the Fukushima Daiichi Nuclear Power Plant evacuation zone, and that some houses may require fungal disinfection. The results suggest that residents' health could be at risk owing to the high levels of airborne fungi and toxic fungi Aspergillus section Circumdati. Therefore, monitoring and decontamination/disinfection of fungi are strongly recommended before residents are allowed to return permanently to their homes. In addition, returning to home with a certain frequency and adequate ventilation are necessary during similar situations, e.g., when residents cannot stay in their homes for a long period, because fungal levels in houses in the Fukushima Daiichi

    Spectrochemical analysis of representative samples of topsoil from urban gardens and from individual fields in rural areas indicates that the level of total copper, EDTA-extractable copper, water-soluble boron, and acetic-acid extractable lead are markedly enhanced in urban areas. No significant differences were discovered between levels of these elements in soils from built-up areas in small towns and large conurbations. These results suggest the possibility of general enhancement of the trace element content of plants grown in private gardens in built-up areas.

    To explore the perceptions of homeless women regarding their experience in a shelter-based garden project to promote mental wellness. Participants planted and tended the vegetable garden and prepared and ate the fruits of their labor. A qualitative descriptive design with a conventional content analysis of narrative data. Data were gathered in semistructured interviews. Participants were homeless daytime shelter guests who had participated in at least eight gardening sessions over 4 weeks. The project was started in the fall of 2010 and the interviews were conducted over 2 months in the summer of 2011. Two polarized themes were identified in the narratives, clustering around negative and positive thoughts. The "dark" theme centered on marginalization and the oppressiveness of shelter life. The "light" theme centered on stress relief, feeling socially included, and personal change. The gardening experience interrupted the participants' negative ruminations, offering stress relief and elements of social inclusion and self-actualization. Gardening is an inexpensive and positive intervention for a population with a high incidence of mental illness and distress.

    1. Analyses of flower-visitor interaction networks allow application of community-level information to conservation problems, but management recommendations that ensue from such analyses are not well characterized. Results of modularity analyses, which detect groups of species (modules) that interact more with each other than with species outside their module, may be particularly applicable to management concerns. 2. We conducted modularity analyses of networks surrounding a rare endemic annual plant, Eriogonum visheri, at Badlands National Park, USA, in 2010 and 2011. Plant species visited were determined by pollen on insect bodies and by flower species upon which insects were captured. Roles within modules (network hub, module hub, connector and peripheral, in decreasing order of network structural importance) were determined for each species. 3. Relationships demonstrated by the modularity analysis, in concert with knowledge of pollen species carried by insects, allowed us to infer effects of two invasive species on E. visheri. Sharing a module increased risk of interspecific pollen transfer to E. visheri. Control of invasive Salsola tragus, which shared a module with E. visheri, is therefore a prudent management objective, but lack of control of invasive Melilotus officinalis, which occupied a different module, is unlikely to negatively affect pollination of E. visheri. Eriogonum pauciflorum may occupy a key position in this network, supporting insects from the E. visheri module when E. visheri is less abundant. 4. Year-to-year variation in species' roles suggests management decisions must be based on observations over several years. Information on pollen deposition on stigmas would greatly strengthen inferences made from the modularity analysis. 5. Synthesis and applications: Assessing the consequences of pollination, whether at the community or individual level, is inherently time-consuming. A trade-off exists: rather than an estimate of fitness effects, the

    Gardening has long been one of most enjoyable pastimes among older adults. Whether gardening activities contribute to the well-being of older adults is a major question. Therefore, the aim of the present study was to clarify the psychophysiological relaxing effects of gardening activities on older adults living in modern institutional care. The study participants were 40 older women aged 79.5 ± 8.09 years (mean ± SD). A cross-over study design was used to investigate the physiological and psychological responses to environments with and without plants. Physiological evaluation was carried out using blood pressure and electroencephalography, and psychological evaluation was carried out using the State-Trait Anxiety Inventory and Semantic Differential method. Blood pressure was significantly lower, and changes in brainwaves were observed. Psychological responses showed that participants were more "comfortable and relaxed" after the plant task than after the control task. In addition, total anxiety levels were significantly lower after carrying out the plant task than after the control task. Our research suggests that gardening activities might enhance physiological and psychological relaxation in older adults. Geriatr Gerontol Int 2018; ••: ••-••. © 2018 Japan Geriatrics Society.

The evidence provides a ca. 850-year record of the sedimentation, hydrology and vegetation of the catchment, allowing the following deductions to be made: 1) the dramatically increased erosion rate of local hill slopes was a result of Polynesian deforestation by fire commencing at an estimated date of 700-550 14 C yr BP, and 2) the subsequent stabilisation of these hill slope soils occurred as a result of establishment of European pasture in the catchment after ca.

    Full Text Available The purpose of the studies was to determine the effects of media containing composts from sewage sludge and potato pulp on the flowering and decorative value of 'Butterfly Yellow with Blotch' parviflorous pansy. In the experiment 14 potting media, including 12 media made of 4 composts, were tested. The percentage of compost mixed with sphagnum peat was 25%, 50% and 75%. The components of particular composts were as follows: I - municipal sewage sludge 70% and straw 30%; II - municipal sewage sludge 70% and sawdust 30%; III - municipal sewage sludge 35%, potato pulp 35% and straw 30%; IV - municipal sewage sludge 35%, potato pulp 35% and sawdust 30%. Two control potting media were used: 1 - sphagnum peat with Osmocote Exact Lo-Start at the dose 5 g×dm-3 and 2 - sphagnum peat with Azofoska at the dose 2.5 g×dm-3. There was no top-dressing during cultivation. The pansies for whose cultivation a slow-release fertiliser was used turned out to have most flowers, but the plants cultivated in compost with peat at the ratio 1:1 had equally abundant flowering. At the generative stage, the pansies in control media were the most decorative and those growing in 25% of compost I, 75% of compost II and 50% of compost III and IV. On the basis of plant valuation scale, quality assessment and the abundance of flowering it was found that the media containing 50% of composts were optimal for pansy cultivation.

    2009-01-01

    Full Text Available A variety of crops are grown in New York City community gardens. Although the production of many crops benefits from pollination by bees, little is known about bee abundance in urban community gardens or which crops are specifically dependent on bee pollination. In 2005, we compiled a list of crop plants grown within 19 community gardens in New York City and classified these plants according to their dependence on bee pollination. In addition, using mark-recapture methods, we estimated the abundance of a potentially important pollinator within New York City urban gardens, the common eastern bumble bee (Bombus impatiens. This species is currently recognized as a valuable commercial pollinator of greenhouse crops. However, wild populations of B. impatiens are abundant throughout its range, including in New York City community gardens, where it is the most abundant native bee species present and where it has been observed visiting a variety of crop flowers. We conservatively counted 25 species of crop plants in 19 surveyed gardens. The literature suggests that 92% of these crops are dependent, to some degree, on bee pollination in order to set fruit or seed. Bombus impatiens workers were observed visiting flowers of 78% of these pollination-dependent crops. Estimates of the number of B. impatiens workers visiting individual gardens during the study period ranged from 3 to 15 bees per 100 m2 of total garden area and 6 to 29 bees per 100 m2 of garden floral area. Of 229 B. impatiens workers marked, all recaptured individuals (45% were found in gardens where they were initially marked. These results indicate an abundance of B. impatiens workers within New York City community gardens and suggest that, at least for certain time periods, many individual workers forage within single gardens. Both findings suggest that B. impatiens may be an especially important pollinator of several common crops grown within community gardens and other urban green spaces

    Few studies have documented whether the behavior changes produced by home garden projects have been maintained after completion of the projects. To determine the benefits and challenges affecting production and consumption of β-carotene-rich vegetables and fruits in a rural South African village 10 years after completion of a home garden project. This cross-sectional survey assessed gardening practices and household consumption of β-carotene-rich vegetables and fruits using a questionnaire (n = 186). Benefits and challenges affecting production and consumption of β-carotene-rich vegetables and fruits were assessed through focus group discussions. Thirty-nine percent of the households currently planted β-carotene-rich vegetables and fruits. Major challenges included lack of fencing, animals eating crops, and lack or shortage of water. Planting materials for β-carotene-rich vegetables were sourced from the community nursery, while papaya was grown from its own seed. Shops were the most likely alternative sources of β-carotene-rich vegetables. The frequency of consumption of orange-fleshed sweet potato, butternut, spinach, and papaya when in season differed significantly, with households planting β-carotene-rich vegetables and fruits having more frequent consumption than households not planting these vegetables and fruits. Households planting β-carotene-rich vegetables and fruits were perceived as "well-to-do" and "healthy" households and as "givers". This study showed that 10 years after the endline evaluation of a home garden project, approximately one-third of the households in the village planted β-carotene-rich vegetables and fruits, which is very similar to the proportion at project completion and a postintervention study that was done 6 years later, despite various challenges, indicating that the practice of planting these vegetables and fruits was continued over the years.

    The Great Lakes region, as defined here, includes the Great Lakes and their drainage basins in Minnesota, Wisconsin, Illinois, Indiana, Ohio, Pennsylvania, and New York. The region also includes the portions of Minnesota, Wisconsin, and the 21 northernmost counties of Illinois that lie in the Mississippi River drainage basin, outside the floodplain of the river. The region spans about 9º of latitude and 20º of longitude and lies roughly halfway between the equator and the North Pole in a lowland corridor that extends from the Gulf of Mexico to the Arctic Ocean.The Great Lakes are the most prominent natural feature of the region (Fig. 1). They have a combined surface area of about 245,000 square kilometers and are among the largest, deepest lakes in the world. They are the largest single aggregation of fresh water on the planet (excluding the polar ice caps) and are the only glacial feature on Earth visible from the surface of the moon (The Nature Conservancy 1994a).The Great Lakes moderate the region’s climate, which presently ranges from subarctic in the north to humid continental warm in the south (Fig. 2), reflecting the movement of major weather masses from the north and south (U.S. Department of the Interior 1970; Eichenlaub 1979). The lakes act as heat sinks in summer and heat sources in winter and are major reservoirs that help humidify much of the region. They also create local precipitation belts in areas where air masses are pushed across the lakes by prevailing winds, pick up moisture from the lake surface, and then drop that moisture over land on the other side of the lake. The mean annual frost-free period—a general measure of the growing-season length for plants and some cold-blooded animals—varies from 60 days at higher elevations in the north to 160 days in lakeshore areas in the south. The climate influences the general distribution of wild plants and animals in the region and also influences the activities and distribution of the human

    Water is the main limiting resource for natural and human systems, but the effect of hydroclimatic variability on woody species in water-limited environments at sub-monthly time scales is not fully understood. Plant-water relationships of single-leaf pinyon pine ( Pinus monophylla) were investigated using hourly dendrometer and environmental data from May 2006 to October 2011 in the Great Basin Desert, one of the driest regions of North America. Average radial stem increments showed an annual range of variation below 1.0 mm, with a monotonic steep increase from May to July that yielded a stem enlargement of about 0.5 mm. Stem shrinkage up to 0.2 mm occurred in late summer, followed by an abrupt expansion of up to 0.5 mm in the fall, at the arrival of the new water year precipitation. Subsequent winter shrinkage and enlargement were less than 0.3 mm each. Based on 4 years with continuous data, diel cycles varied in both timing and amplitude between months and years. Phase shifts in circadian stem changes were observed between the growing season and the dormant one, with stem size being linked to precipitation more than to other water-related indices, such as relative humidity or soil moisture. During May-October, the amplitude of the phases of stem contraction, expansion, and increment was positively related to their duration in a nonlinear fashion. Changes in precipitation regime, which affected the diel phases especially when lasting more than 5-6 h, could substantially influence the dynamics of water depletion and replenishment in single-leaf pinyon pine.

    On 11 March 2011, the Great East Japan Earthquake followed by a powerful tsunami hit the Pacific Coast of Northeast Japan and damaged Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Plant, causing a radiation hazard in Fukushima Prefecture. The objective of this report is to describe some results of a questionnaire-based pregnancy and birth survey conducted by the Radiation Medical Science Center for the Fukushima Health Management Survey. Questionnaires were sent to women who received maternal and child health handbooks from municipal officers in Fukushima Prefecture between 1 August 2010 and 31 July 2011, with the aim of reaching those who were pregnant at the time of the disaster. Mailing began 18 January 2012. Data were analyzed separately for six geographic areas in Fukushima Prefecture. The total number of women meeting survey criteria was 15,972. The number of responses received to date is 9,298 (58.2%). Data from 8602 respondents were analyzed after excluding 634 invalid responses and 5 induced and 57 spontaneous abortions (less than 22 gestational weeks). The incidences of stillbirth (over 22 completed gestational weeks), preterm birth, low birth weight and congenital anomalies were 0.25%, 4.4%, 8.7% and 2.72%, respectively. These incidences are similar to recent averages elsewhere in Japan. Considering the pregnancy and birth survey data in aggregate, our disaster seemed to provoke no significant adverse outcomes over the whole of Fukushima prefecture. But post-disaster prenatal care and support intended for patients' safety and security should be coupled with ongoing surveillance and rigorous data analysis.

    Leaf-cutter ants use fresh plant material to grow a mutualistic fungus that serves as the ants' primary food source. Within fungus gardens, various plant compounds are metabolized and transformed into nutrients suitable for ant consumption. This symbiotic association produces a large amount of refuse consisting primarily of partly degraded plant material. A leaf-cutter ant colony is thus divided into two spatially and chemically distinct environments that together represent a plant biomass degradation gradient. Little is known about the microbial community structure in gardens and dumps or variation between lab and field colonies. Using microbial membrane lipid analysis and a variety of community metrics, we assessed and compared the microbiota of fungus gardens and refuse dumps from both laboratory-maintained and field-collected colonies. We found that gardens contained a diverse and consistent community of microbes, dominated by Gram-negative bacteria, particularly gamma-Proteobacteria and Bacteroidetes. These findings were consistent across lab and field gardens, as well as host ant taxa. In contrast, dumps were enriched for Gram-positive and anaerobic bacteria. Broad-scale clustering analyses revealed that community relatedness between samples reflected system component (gardens/dumps) rather than colony source (lab/field). At finer scales samples clustered according to colony source. Here we report the first comparative analysis of the microbiota from leaf-cutter ant colonies. Our work reveals the presence of two distinct communities: one in the fungus garden and the other in the refuse dump. Though we find some effect of colony source on community structure, our data indicate the presence of consistently associated microbes within gardens and dumps. Substrate composition and system component appear to be the most important factor in structuring the microbial communities. These results thus suggest that resident communities are shaped by the plant degradation

School garden practices, attitudes associated with the use of gardens in schools, and perceptions of barriers to having and using school gardens in academic instruction. Descriptive statistics and chi-square; P science, environmental studies, and nutrition. Principals strongly agreed that resources such as curriculum materials linked to academic instruction and lessons on teaching nutrition in the garden would assist in the school garden being used for academic instruction. Principals deemed the garden as being not to slightly effective at enhancing the school meal program. School gardens appear to be predominantly used by most schools to enhance academic instruction. There is a need for curriculum materials and teacher training for gardening and nutrition. The link between the garden and the school meal program is an area that clearly requires attention. School lunch would be a logical setting for provision of edible produce, in addition to taste-testing of fresh produce in the garden or classroom setting.

    Edinburgh has had eight physic gardens on different sites since its first one was created by the Incorporation of Barbers and Surgeons in 1656. As the gardens grew in size, they evolved from herb gardens to botanic gardens with small herbaria for the supply of medical herbs. They were intended for the instruction of medical, surgical and apothecary students and, in the case of the physicians, to demonstrate the need for a physicians' college and a pharmacopoeia. Some of the doctors in charge of them were equally famous and influential in botany as in medicine, and while Edinburgh Town Council enjoyed the fame the gardens brought to the city it was parsimonious and slow to support its botanical pioneers. The gardens are celebrated today in the Sibbald Garden within the Royal College of Physicians of Edinburgh.

    of the ideals of environmental conservation after their visit to the garden. Secondly, the study determined the spatial preferences of visitors to the garden which was thirdly correlated to the time that they spent at each area. A number of recommendations were made and a comparative study followed twelve years after the initial study in which the implementation of the resultant findings was determined through observation and a comparison of information pamphlets and garden layout maps. It was found that large-scale changes took place in line with the recommendations made after the initial study. These included the demolition of unsuccessful theme gardens and their replacement by topical theme gardens such as water-wise gardens and a garden that attracts butterflies and birds. The educational function of the Walter Sisulu National Botanical Garden was greatly improved by adding more information plaques throughout the garden, a new interpretative centre and many additional information pamphlets that had been absent during the initial study. Major structural changes were made, such as the building of an amphitheatre which reduced the negative impact of noise and disturbance surrounding the nests of the Verreaux’s eagles that breed successfully in the garden. The changes undertaken at the garden show innovative improvements in line with the con servation principles outlined by the South African National Biodiversity Institute (SANBI. The evidence of the implementation of research recommendations from the initial study could play a direct role in improving the visitor experience, which would facilitate the economic viability of the Walter Sisulu National Botanical Garden in its endeavours to reach its conservation goals. Further research is suggested to continuously determine the areas of preference of visitors in the evolving landscape of the garden to ensure renewed interest of visitors to the garden. If botanical gardens want to succeed in their goal to increase

    Yéego Gardening! is a community garden intervention to increase gardening behavior, increase access to low-cost fruit and vegetables, and ultimately increase consumption in Navajo communities. To design a theory-based, culturally relevant intervention with three components: a community garden, monthly workshops on gardening and healthy eating, and community outreach. Gardens were constructed and maintained in collaboration with community-based organizations in two Navajo communities. Monthly workshops were held throughout the growing season and incorporated aspects of Navajo culture and opportunities to build confidence and skills in gardening and healthy eating behaviors. In addition, program staff attended community events to promote gardening and healthy eating. Community input was essential throughout the planning and implementation of the intervention. If effective, community gardens may be a way to increase fruit and vegetable availability and intake, and ultimately reduce risk of obesity and diabetes.

    Prescription and nonprescription drugs have been detected in rivers and streams in Europe and the United States. Sewage treatment plants (STPs) are an important source of these contaminants, but few data exist on the spatial distribution of drugs in surface waters near STPs. Samples of surface water were collected in the summer and fall of 2000 at open-water sites in the lower Great Lakes (Lake Ontario and Lake Erie), at sites near the two STPs for the city of Windsor (ON, Canada), and at sites in Hamilton Harbour (ON, Canada), an embayment of western Lake Ontario that receives discharges from several STPs. In a follow-up study in the summer of 2002, samples of surface water and final effluent from adjacent STPs were collected from sites in Hamilton Harbour and Windsor. In addition, surface water and STP effluent samples were collected in Peterborough (ON, Canada). All samples of surface water and STP effluents were analyzed for selected acidic and neutral drugs. In the survey of Hamilton Harbour and Windsor conducted in 2000, acidic drugs and the antiepileptic drug carbamazepine were detected at ng/L concentrations at sites that were up to 500 m away from the STP, but the hydrological conditions of the receiving waters strongly influenced the spatial distribution of these compounds. Drugs were not detected at open-water locations in western Lake Erie or in the Niagara River near the municipality of Niagara-on-the-Lake (ON, Canada). However, clofibric acid, ketoprofen, fenoprofen, and carbamazepine were detected in samples collected in the summer of 2000 at sites in Lake Ontario and at a site in the Niagara River (Fort Erie, ON, Canada) that were relatively remote from STP discharges. Follow-up studies in the summer of 2002 indicated that concentrations of acidic and neutral drugs in surface waters near the point of sewage discharge into the Little River (ON, Canada) STP were approximately equal to the concentrations in the final effluent from the STP.

Possible spin-off applications of hydrophonics experiments are noted. It is projected that long-term goals will include the integration of this garden system into the process of waste recycling for fertilization, air refreshment, and potable water recovery in a closed environment. The Biomass Production Chamber, a two-story bubble-shape steel biosphere modified from a Mercury/Gemini program attitude chamber provides a usable volume of 7.3 m x 3.6 m in diameter containing growing racks, piping for nutrient solutions, specialized lighting and sensors that provide information to the computers controlling the chamber and its functions. Computer programs provide highly sensitive monitoring and regulation of the system. Crops successfully harvested to date include dwarf wheat, lettuce, and soybeans.

    Measurement and decontamination of surface of trees and surrounding wooden structures contaminated by radioactive substance were studied in the gardens and public parks of Northern Fukushima Prefecture which experienced radioactive contamination due to the accident at the TEPCO's Fukushima Daiichi Nuclear Power Plant. The counts per minute (CPM) above the centre surface of wooden garden tables in open air were 1.5 times higher than those of garden benches and 9 times higher than that of a garden bench in the square gazebo. Decontamination of wooden garden benches by high-pressure washing was more effective than planing. The counts per minute (CPM) above the soil around garden trees increased by 1.2 times after high-pressure washing. Radioactivity counting rate did not decrease when the leaves fallen from zelocova trees were removed; however, they decreased by about half when soil cover was installed at the base of the trees. Clearly, the upper surfaces of garden trees and wooden surrounding structures were strongly contaminated by radioactive substances, and they should be decontaminated by high-pressure washing before removing the surface soil.

    2016-11-01

    Full Text Available Throughout history, gardens and garden designing has been in the attention of Persian architects who had special expertise in the construction of gardens. The appearance of Islam and allegories of paradise taken from that in Koran and Saints’ sayings gave spirituality to garden construction. Climate conditions have also had an important role in this respect but little research has been done about it and most of the investigations have referred to spiritual aspects and forms of garden. The cold and dry climate that has enveloped parts of West and North West of Iran has many gardens with different forms and functions, which have not been paid much attention to by studies done so far. The aim of this paper is to identify the features and specifications of cold and dry climate gardens with an emphasis on Tabriz’s Gardens.  Due to its natural and strategic situation, Tabriz has always been in the attention of governments throughout history; travellers and tourists have mentioned Tabriz as a city that has beautiful gardens. But, the earthquakes and wars have left no remains of those beautiful gardens. This investigation, by a comparative study of the climates in Iran and the effect of those climates on the formation of gardens and garden design, tries to identify the features and characteristics of gardens in cold and dry climate. The method of study is interpretive-historical on the basis of written documents and historic features and field study of existing gardens in this climate. The results show that, with respect to natural substrate, vegetation, the form of water supply, and the general form of the garden; gardens in dry and cold climate are different from gardens in other climates.

    American Indians, including Navajo, are disproportionately affected by obesity and diabetes, in part due to diet-related health behaviors. The purpose of this study was to assess the patterns of gardening and fruit and vegetable (FV) consumption among residents in two communities on the Navajo Nation in order to inform a community gardening intervention. We analyzed survey data collected from participants in the Yéego Gardening study conducted in two communities in the Navajo Nation (N = 169). We found that 51% of the sample gardened, and on average participants gardened 8.9 times per month. Lack of time (53%) and financial barriers, such as gas for transportation or irrigation (51 and 49%, respectively), were reported as barriers to gardening. Most participants reported low levels of self-efficacy (80%) and behavioral capability (82%) related to gardening. Those with higher levels of gardening self-efficacy and behavioral capability reported more frequent gardening. Average daily FV consumption was 2.5 servings. Most participants reported high levels of self-efficacy to eat FV daily (64%) and high behavioral capability to prepare FV (66%). There was a positive association between FV consumption and gardening, with those gardening more than 4 times per month eating about 1 more serving of FV per day than those gardening 4 or fewer times per month. Further research is needed to better understand how gardening can increase fruit and vegetable availability and consumption among residents of the Navajo Nation.

  16. Monoculture of leafcutter ant gardens.

    Directory of Open Access Journals (Sweden)

    Ulrich G Mueller

    2010-09-01

    Full Text Available Leafcutter ants depend on the cultivation of symbiotic Attamyces fungi for food, which are thought to be grown by the ants in single-strain, clonal monoculture throughout the hundreds to thousands of gardens within a leafcutter nest. Monoculture eliminates cultivar-cultivar competition that would select for competitive fungal traits that are detrimental to the ants, whereas polyculture of several fungi could increase nutritional diversity and disease resistance of genetically variable gardens.Using three experimental approaches, we assessed cultivar diversity within nests of Atta leafcutter ants, which are most likely among all fungus-growing ants to cultivate distinct cultivar genotypes per nest because of the nests' enormous sizes (up to 5000 gardens and extended lifespans (10-20 years. In Atta texana and in A. cephalotes, we resampled nests over a 5-year period to test for persistence of resident cultivar genotypes within each nest, and we tested for genetic differences between fungi from different nest sectors accessed through excavation. In A. texana, we also determined the number of Attamyces cells carried as a starter inoculum by a dispersing queens (minimally several thousand Attamyces cells, and we tested for genetic differences between Attamyces carried by sister queens dispersing from the same nest. Except for mutational variation arising during clonal Attamyces propagation, DNA fingerprinting revealed no evidence for fungal polyculture and no genotype turnover during the 5-year surveys.Atta leafcutter ants can achieve stable, fungal monoculture over many years. Mutational variation emerging within an Attamyces monoculture could provide genetic diversity for symbiont choice (gardening biases of the ants favoring specific mutational variants, an analog of artificial selection.

  18. Exploring the Relationship between Prior Knowledge on Rain Gardens and Supports for Adopting Rain Gardens Using a Structural Equation Model

    Directory of Open Access Journals (Sweden)

    Suyeon Kim

    2018-05-01

    Full Text Available The objective of this study was to determine the effect of prior knowledge and visual evaluation on supports for rain garden installations. To achieve this objective, a survey was conducted to obtain prior knowledge of rain gardens, rain garden implementation support ratings, and visual evaluation of rain gardens in 100 visitors of three rain garden sites. Results of the analysis revealed that users’ visual evaluation of rain gardens played a role as a moderator in the relationship between prior knowledge and support for rain garden installations. In other words, education and publicity of rain gardens alone cannot increase support for rain gardens. However, if rain gardens are visually evaluated positively, the effects of education and publicity of rain gardens can be expected. Therefore, to successfully apply a rain garden policy in the future, basic consideration should be given to aesthetics in order to meet visitors’ visual expectations prior to education and publicity of rain gardens.

    The aim of the study is to show that the financial resources needed for exploitation of the energetical resources as well as for the security of great energetical structures (i.e. nuclear power plants (NPP), deep mines, great waterdams, etc.), can be employed with high efficiency only when using appropriate basic and applied geological and geophysical investigations. One can only by this way save money expended during the last years to great structures built in critical regions. The breakdown of the Chernobyl NPP and the catastrophic earthquake in Armenia as well as the construction of a NPP there, situated on the Ararat deep fault, in a relatively small distance from the earthquake region, warn us and constitute the main reason for the realization of the research programme presented here as well as for the recommendation of this research programme to be solved within the framework of a Pentagonal group.

    Integration of pollen records, and fossil woodrat midden data recovered from multiple strata of fossil woodrat (Neotoma spp.) dens (middens) in both northern and southern Nevada reveal a detailed paleoclimatic proxy record for the Great Basin during the last 45,000 years in growing detail. Clear, late Holocene climate-linked elevational depressions of plant species' distributions have occurred throughout the Great Basin of up to 200 m below today's and by as much as 1000 m below what they were during the middle Holocene. Horizontal plant range extentions during the Holocene reflecting the final northern most adjustments to Holocene climates range up to several hundred kilometers in the Great Basin. Well documented lags evidenced in the late Holocene response of vegetation communities to increased precipitation indicate reduced effectiveness in the ability of plant communities to assimilate excess precipitation. This resulted in significant runoff that was available for recharge. These responses, although indicating both rapid and dramatic fluctuations of climate for the Holocene, fall far short of the scale of such changes during the late Pleistocene. Extension of these results to Pleistocene woodrat den and pollen data evidence spans lasting several hundred to a thousand or more years during which significantly greater amounts of precipitation would have been available for runnoff or recharge

Sensory gardens and horticultural activities are increasingly used in dementia care, yet their benefits are uncertain. A modified scoping review with descriptive analysis of selected empirical studies. Systematic searches in Amed, CINAHL, MEDLINE, ISI Web of Science, Embase and Scopus were used. Search terms were the free-text concepts 'healing garden', 'horticultural therapy', 'restorative garden' and 'wander garden' which were combined with dementia and Alzheimer. Sixteen studies were included with included participants ranging from eight to 129 participants. Research designs were case studies (n = 2), survey (n = 1), intervention studies with pretest/post-test design (n = 11) and randomised controlled studies (n = 2). Of these 16 studies, eight examined the benefits of sensory gardens, seven examined horticultural therapy or therapeutic horticulture and one examined the use of plants indoors. This study offers a review of the research addressing benefits of sensory gardens, therapeutic horticulture, horticultural therapy and other purposeful use of plants in dementia care. The reported findings are mainly on issues related to behaviour, affect and well-being. The findings are in general mutually supportive, however, with some contradictory findings. In addition, sleep pattern, well-being and functional level seem to improve. These types of nonpharmacological interventions may improve well-being and affect and reduce the occurrence of disruptive behaviour. Additionally, the use of psychotropic drugs, incidents of serious falls, sleep and sleep pattern also seem to improve. To further improve the use of the existing or planned gardens, an educational programme for staff that also includes skill training is recommended. © 2013 John Wiley & Sons Ltd.

    Urbanization negatively affects biodiversity, yet some urban habitat features can support diversity. Parasitoid wasps, an abundant and highly diverse group of arthropods, can inhabit urban areas and do well in areas with higher host abundance, floral resources, or local or landscape complexity. Parasitoids provide biological control services in many agricultural habitats, yet few studies have examined diversity and abundance of parasitoids in urban agroecosystems to understand how to promote conservation and function. We examined the local habitat and landscape drivers of parasitoid abundance, superfamily and family richness, and parasitoid composition in urban gardens in the California central coast. Local factors included garden size, ground cover type, herbaceous plant species, and number of trees and shrubs. Landscape characteristics included land cover and landscape diversity around gardens. We found that garden size, mulch cover, and urban cover within 500 m of gardens predicted increases in parasitoid abundance within gardens. The height of herbaceous vegetation and tree and shrub richness predicted increases in superfamily and family richness whereas increases in urban cover resulted in declines in parasitoid richness. Abundance of individual superfamilies and families responded to a wide array of local and landscape factors, sometimes in opposite ways. Composition of parasitoid communities responded to changes in garden size, herbaceous plant cover, and number of flowers. Thus, both local scale management and landscape planning may impact the abundance, diversity, and community composition of parasitoids in urban gardens, and may result in differences in the effectiveness of parasitoids in biological control. © The Authors 2017.

    2009-01-01

    The predominantly tropical climate and the predominance of plateaus in Brazil contributed to the development of a high hydroelectric potential, which determined the choice of hydropower plants as main technology of electricity generation. Though this is a renewable source, dams must being established to guarantee high amount of water all over the year generating high environmental and social impact. One of the ways to evaluate environmental impacts caused by large hydropower plants is adoption of environmental indexes which are formed by ratio of installed or firm power with dam area of a hydropower plant. The objective of this study is to evaluate the impact caused by these dams through the use of environmental indexes. Statistical instruments were utilized to evaluate environmental indexes in the five Brazilian regions, twenty six states, and fifteen main rivers (where at least three large hydropower plants are encountered). The periods when each hydropower plant operation was initiated were also considered. In this study, the greatest media values were found in South, Southeast, and Northeast regions respectively, and the smallest media values were found in North and Mid-West regions, respectively. More, the greatest encountered media indexes were also found in dams established in the 1950s. (author)

    Beryllium-7 is a natural radionuclide produced by cosmic rays. Be-7 is found vividly in the atmosphere, so the concentrations in airborne particles were analyzed by many investigators. It is known that airborne particles with Be-7 in the atmosphere fall slowly to the ground and adhere to plant surface. However, Be-7 concentrations of foods were not measured too much. So we measured Be-7 concentrations of garden vegetables, wild vegetables, grasses, beef and milk, and calculated internal exposure dose from Be-7. Beryllium-7 concentrations of plant samples are shown. Beryllium-7 concentrations of garden vegetables were from 0.2 to 25.3 Bq/kg, and concentrations of wild vegetables were from 0.8 to 23.5 Bq/kg. There is no difference in Be-7 concentrations between garden vegetables and wild vegetables. Leaf vegetables have almost higher concentration of Be-7. Though Matteuccia Struthiopteris and Pteridium aquilinum are ferns, their eatable stages are sprouts. The relationship between surface area and Be-7 concentration in some vegetable leaves gathered simultaneously at the same farm is shown. Beryllium-7 concentrations of leaves correlate significantly with the surface area/weight ratios. What high concentration vegetables have proportionately broad leaves suggests that atmospheric Be-7 particles adhere to surface of leaves. (author)

  15. Cultural Consumption of the Overseas Chinese Garden in the Process of Cross-cultural Communication

    2015-08-01

    When referring to the tangible cultural heritage, people tend to concern more about the conservation and research of the entity of the tangible heritage than the cross-cultural communication of the cultural heritage which is also one of the most important components of the preservation of the cultural heritage. As an exotic new born of the cultural heritage, the entity born from the cross-cultural communication inherits the properties of the cultural heritage on the one hand, and on the other hand generates diversities as a result of the differences based on social, cultural and environment. And the business model is one of the most important reasons for the production of diversities. There's no doubt that a good form of business model makes great significance to the cross-cultural communication. Therefore, the study of the business model of cultural heritage in the process of cross-cultural communication will not only contributes to the deeper understanding towards the phenomenon of the cultural heritage's cross-cultural communication, but also leads to the introspection to the tangible cultural heritage itself. In this way, a new kind of conservative notion could take form, and the goal of protecting cultural heritage could be achieved. Thus the Chinese Garden is a typical representation of the cultural heritage which makes great sense in the cross-cultural communication. As a kind of tangible cultural heritage, the Chinese gardens are well preserved in different regions in China. While the spirits of the Chinese garden carry forward through the construction of the Chinese gardens abroad during the cross-cultural communication. As a new kind of form of the cross-cultural communication of the cultural heritage, on the one hand, the Chinese gardens overseas built ever since China's Reform and Opening express creatively of the materialist and the spirituality of the traditional Chinese Garden, and on the other hand, those Chinese gardens overseas face all kinds of

    Previous research has suggested that gardening activity could be an effective form of regular exercise for improving physical and psychological health in later life. However, there is a lack of data regarding the exercise intensities of various gardening tasks across different types of gardening and different populations. The purpose of this study was to examine the exercise intensity of gardening activity for older adult allotment gardeners in Wales, United Kingdom following a similar procedure used in previous studies conducted in the United States and South Korea by Park and colleagues (2008a; 2011). Oxygen consumption (VO2) and energy expenditure for six gardening tasks were measured via indirect calorimetery using the portable Oxycon mobile device. From these measures, estimated metabolic equivalent units (METs) were calculated. Consistent with Park et al. (2008a; 2011) the six gardening tasks were classified as low to moderate-high intensity physical activities based on their metabolic values (1.9-5.7 METs).

    To test the hypothesis that gardening is beneficial for survival after taking time-dependent comorbidities, mobility, and depression into account in a longitudinal middle-aged (50-64 years) and older (≥65 years) cohort in Taiwan. The cohort contained 5,058 nationally sampled adults ≥50 years old from the Taiwan Longitudinal Study on Aging (1996-2007). Gardening was defined as growing flowers, gardening, or cultivating potted plants for pleasure with five different frequencies. We calculated hazard ratios for the mortality risks of gardening and adjusted the analysis for socioeconomic status, health behaviors and conditions, depression, mobility limitations, and comorbidities. Survival models also examined time-dependent effects and risks in each stratum contingent upon baseline mobility and depression. Sensitivity analyses used imputation methods for missing values. Daily home gardening was associated with a high survival rate (hazard ratio: 0.82; 95% confidence interval: 0.71-0.94). The benefits were robust for those with mobility limitations, but without depression at baseline (hazard ratio: 0.64, 95% confidence interval: 0.48-0.87) when adjusted for time-dependent comorbidities, mobility limitations, and depression. Chronic or relapsed depression weakened the protection of gardening. For those without mobility limitations and not depressed at baseline, gardening had no effect. Sensitivity analyses using different imputation methods yielded similar results and corroborated the hypothesis. Daily gardening for pleasure was associated with reduced mortality for Taiwanese >50 years old with mobility limitations but without depression.

    Concern over declining pollinators has led to multiple conservation initiatives for improving forage for bees in agroecosystems. Using data available through the Pollinator Library (npwrc.usgs.gov/pollinator/), we summarize plant-pollinator interaction data collected from 2012-2015 on lands managed by the U.S. Fish and Wildlife Service and private lands enrolled in U.S. Department of Agriculture conservation programs in eastern North Dakota (ND). Furthermore, we demonstrate how plant-pollinator interaction data from the Pollinator Library and seed cost information can be used to evaluate hypothetical seeding mixes for pollinator habitat enhancements. We summarize records of 314 wild bee and 849 honey bee (Apis mellifera L.) interactions detected on 63 different plant species. The wild bee observations consisted of 46 species, 15 genera, and 5 families. Over 54% of all wild bee observations were represented by three genera-Bombus, Lassioglossum, and Melissodes. The most commonly visited forbs by wild bees were Monarda fistulosa, Sonchus arvensis, and Zizia aurea. The most commonly visited forbs by A. mellifera were Cirsium arvense, Melilotus officinalis, and Medicago sativa. Among all interactions, 13% of A. mellifera and 77% of wild bee observations were made on plants native to ND. Our seed mix evaluation shows that mixes may often need to be tailored to meet the unique needs of wild bees and managed honey bees in agricultural landscapes. Our evaluation also demonstrates the importance of incorporating both biologic and economic information when attempting to design cost-effective seeding mixes for supporting pollinators in a critically important part of the United States.

    Bailey, Joseph; Field, Richard; Boyd, Doreen

    2016-04-01

    We assess the scale-dependency of the relationship between biodiversity and novel geodiversity information by studying spatial patterns of native and alien (archaeophytes and neophytes) vascular plant species richness at varying spatial scales across Great Britain. Instead of using a compound geodiversity metric, we study individual geodiversity components (GDCs) to advance our understanding of which aspects of 'geodiversity' are most important and at what scale. Terrestrial native (n = 1,490) and alien (n = 1,331) vascular plant species richness was modelled across the island of Great Britain at two grain sizes and several extent radii. Various GDCs (landforms, hydrology, geology) were compiled from existing national datasets and automatically extracted landform coverage information (e.g. hollows, valleys, peaks), the latter using a digital elevation model (DEM) and geomorphometric techniques. More traditional predictors of species richness (climate, widely-used topography metrics, land cover diversity, and human population) were also incorporated. Boosted Regression Tree (BRT) models were produced at all grain sizes and extents for each species group and the dominant predictors were assessed. Models with and without geodiversity data were compared. Overarching patterns indicated a clear dominance of geodiversity information at the smallest study extent (12.5km radius) and finest grain size (1x1km), which substantially decreased for each increase in extent as the contribution of climatic variables increased. The contribution of GDCs to biodiversity models was chiefly driven by landform information from geomorphometry, but hydrology (rivers and lakes), and to a lesser extent materials (soil, superficial deposits, and geology), were important, also. GDCs added significantly to vascular plant biodiversity models in Great Britain, independently of widely-used topographic metrics, particularly for native species. The wider consideration of geodiversity alongside

    Urban gardening is a growing global phenomenon with a positive impact on society. Despite several associated benefits, growing vegetables in urban gardens that are localized in highly polluted areas poses questions about the safety of the produced food. Therefore, the identification of risk factors that result in possible deleterious effects to human health is important for realizing all of the benefits to society. We evaluated the use of two biomonitoring methods in ten urban gardens of Sao Paulo city and one control site: the micronuclei frequencies for early tetrads of Tradescantia pallida (Rose) Hunt. cv. "Purpurea" Boom (hereafter, Trad-MCN) as a short-term indicator of genotoxic response and tree barks to quantify the accumulation of traffic-related chemical elements as a long-term biomarker of air pollution in urban gardens. Mature plants of Tradescantia pallida were exposed in each garden, and their inflorescences were sampled over three months. A random set of 300 early tetrads in 13 to 21 slides per garden were evaluated for micronuclei frequencies. Elemental concentrations in 428 tree barks samples from 107 different trees in the areas surrounding urban gardens were quantified using an energy dispersive X-ray fluorescence spectrometer. The frequency of Trad-MCN has a significant correlation with traffic variables and chemical elements related to road dust and tailpipe emissions deposited in tree barks. Negative associations between Trad-MCN and both the distance through traffic and the presence of vertical obstacles were observed in the community gardens. The Mn/Zn concentrations in tree barks were associated with increased Trad-MCN. Copyright © 2016 Elsevier B.V. All rights reserved.

    The Great East Japan Earthquake in 2011 caused 2 other serious disasters: a tsunami and a nuclear power plant accident. A chronic shortage of mental health resources had been previously reported in the Tohoku region, and the triple disaster worsened the situation. Eventually a public health approach was implemented by providing a common room in temporary housing developments to build a sense of community and to approach evacuees so that they could be triaged and referred to mental health teams. Japan now advocates using psychological first aid to educate first responders. This article extracts key lessons from relevant literature. Copyright © 2013 Elsevier Inc. All rights reserved.

    This community-based participatory research project used popular education techniques to support and educate Hispanic farmworker families in planting and maintaining organic gardens. Measures included a pre- post gardening survey, key informant interviews and observations made at community-based gardening meetings to assess food security, safety and family relationships. Thirty-eight families enrolled in the study during the pre-garden time period, and four more families enrolled in the study during the post-garden period, for a total of 42 families enrolled in the 2009 gardening season. Of the families enrolled during the pre-gardening time period there were 163 household members. The mean age of the interviewee was 44.0, ranging from 21 to 78 years of age. The median number of occupants in a household was 4.0 (range: 2-8), Frequency of adult vegetable intake of "Several time a day" increased from 18.2 to 84.8%, (P gardening season, the sum of the frequencies of "Sometimes" and "Frequently" worrying in the past month that food would run out before money was available to buy more was 31.2% and the sum of these frequencies dropped to 3.1% during the post garden period, (P = 0.006). The frequency of skipping meals due to lack of money was not statistically significantly different before and after the gardening season for either adults or children. Analysis of text responses and key informant interviews revealed that physical and mental health benefits were reported as well as economic and family health benefits from the gardening study, primarily because the families often worked in their gardens together. A community gardening program can reduce food insecurity, improve dietary intake and strengthen family relationships.

    Full Text Available The aim of the article is the studying of a frequently seen phenomenon, which is the loss of value as far as some buildings and their surroundings are concerned, which, at the moment of their construction, held great historical and architectural value, but in time they have gradually lost their value due to political, social, and cultural changes. In the Banat region of the first half of the 19th century, we can remark the dominance of the neoclassical style. The parks of the Banat region, apart from their role of satisfying the visual aesthetic appearances, are very well adapted to the place. They are unique, but the pattern after which they were conceived is common, according to the fashion of the era in which they were created. The subject of the research develops around the historical gardens belonging to certain historical monuments. The aim of researching these landscape arrangements is the investigation of the present-day situation and their evolution that has led to their actual transformation.

    Full Text Available Traditional or local knowledge is a major issue to be focused on, particularly since the implementation of the Strategic Plan for Biodiversity 2011–2020 and the Aichi Targets “Living in Harmony with Nature”. According to the strategic goals, by 2020, conservation of biodiversity and its sustainable use incorporate what local and indigenous communities have within their traditional knowledge, innovation and practice and their customary use of biological resources are respected at all relevant levels. The older generation among the local people usually use medicinal herbs for various ailments, health care and other cultural purposes. However, encroaching industrialization and the changes in today’s life styles are responsible for the decreasing practice in the local use of herbs especially for healing purposes. It is, therefore, felt worthwhile to encourage young generations such as school children to gain knowledge about these local herbs and record the native uses of these herbs before the information is lost. One biodiversity education program was conducted to facilitate secondary school students to set up a themed garden and find out the local knowledge of the plants they grew in their garden from their family members or communities. The findings revealed that students’ local knowledge on healing improved after they joined the program. Therefore, it is proposed that the themed garden project can enhance students’ local knowledge.

    Full Text Available Garden pea (Pisum sativum L is an important winter legume used as fresh vegetables and other drier food products. Despite of its importance as cash crop in many parts of Nepal, much study on various aspects for enhancing production and productivity has yet to be done. Therefore, to evaluate the production performance different genotypes of garden pea in eastern hills agro-ecological conditions present experiments were carried out consecutively for two years (2015 and 2016 at Agricultural Research Station, Pakhribas. The experiment comprised of 11 different genotypes of garden pea including a check variety Arkel. The production performance was evaluated in a completely randomized block design with three replications. The seeds were sown at 50 × 10 cm spacing during first week of October for two years. The result showed that DGP-05 genotype had earliest 104 days after sowing.

  19. Growing community : rooftop gardens for affordable housing

    Energy Technology Data Exchange (ETDEWEB)

    Weeks, K.N. [California Univ., Berkeley, CA (United States)

    2007-07-01

    This paper reviewed the processes used in recently designed affordable housing roof garden projects in California, Montana and Georgia. Gardens create a sense of community through shared space and social interactions. As such, roof gardens can give residents of affordable housing the opportunity to experience the community-fostering benefits of gardening, with the added advantages of potentially lower energy bills and wastewater fees. The factors that should be considered in planning, design, construction and maintenance of roof gardens for affordable housing were also outlined. As places of refuge, gardens help people relax and promote healing, which is particularly important for physical, emotional, social and economic well-being. For the many residents of affordable housing who earn less than 50 per cent of the area median income, gardens offer a venue for establishing relationships with neighbours, many of whom they might otherwise never meet. They also offer a means to improved nutrition and food security, education and positive recreation for youth, and better aesthetic surroundings. While motivations for choosing green roofs varied widely across the projects, affordability was linked to 3 main areas, namely saving costs in design, construction and operations; getting the roof to generate funding; and, improving the quality of life in affordable housing. 17 refs., 12 figs.

    A programme of garden-related indoor activities was developed to sustain a gardening group for people with mid to late stage Huntington's disease during the winter. The activities were devised by the horticulturist, working empirically, involving the services occupational therapist, physiotherapist, occupational therapy art technician, computer room, recreation and leisure staff. The programme was strongly supported by the nursing and care staff. Feedback on the effectiveness of the activities was sought from the clients, team members and unit staff. The clients' interest in gardening was sustained by a multidisciplinary programme of indoor growing and using plant products in creative activities, computing and group projects. The clients enjoyed all activities except one that they said lacked contact with plants. The inexpensive programme of activities enabled creativity and self-expression, stimulated social contact and helped with therapeutic goals of the clients. In addition, it engaged the multi-disciplinary team and the unit staff, was practical and enhanced the environment.

    Stress-relieving effects of gardening were hypothesized and tested in a field experiment. Thirty allotment gardeners performed a stressful Stroop task and were then randomly assigned to 30 minutes of outdoor gardening or indoor reading on their own allotment plot. Salivary cortisol levels and self-reported mood were repeatedly measured. Gardening and reading each led to decreases in cortisol during the recovery period, but decreases were significantly stronger in the gardening group. Positive mood was fully restored after gardening, but further deteriorated during reading. These findings provide the first experimental evidence that gardening can promote relief from acute stress.

    The dry landscape garden at Ryoanji Temple in Kyoto, Japan, a UNESCO world heritage site, intrigues hundreds of thousands of visitors every year with its abstract, sparse and seemingly random composition of rocks and moss on an otherwise empty rectangle of raked gravel. Here we apply a model of shape analysis in early visual processing to show that the 'empty' space of the garden is implicitly structured and critically aligned with the temple's architecture. We propose that this invisible design creates the visual appeal of the garden and was probably intended as an inherent feature of the composition.

    In Japan, participants in the disaster-specific medical transportation system have received ongoing training since 2002, incorporating lessons learned from the Great Hanshin Earthquake. The Great East Japan Earthquake occurred on March 11, 2011, and the very first disaster-specific medical transport was performed. This article reviews in detail the central government's control and coordination of the disaster medical transportation process following the Great East Japan Earthquake and the Fukushima Daiichi Nuclear Power Plant Accident. In total, 124 patients were air transported under the coordination of the C5 team in the emergency response headquarter of the Japanese Government. C5 includes experts from the Cabinet Office, Cabinet Secretariat, Fire Defense Agency, Ministry of Health, Labour and Welfare, and Ministry of Defense. In the 20-30 km evacuation zone around the Fukushima Daiichi nuclear power plant, 509 bedridden patients were successfully evacuated without any fatalities during transportation. Many lessons have been learned in disaster-specific medical transportation. The national government, local government, police, and fire agencies have made significant progress in their mutual communication and collaboration. Fortunately, hospital evacuation from the 20-30 km area was successfully performed with the aid of local emergency physicians and Disaster Medical Assistance Teams (DMATs) who have vast experience in patient transport in the course of day-to-day activities. The emergency procedures that are required during crises are an extension of basic daily procedures that are performed by emergency medical staff and first responders, such as fire fighters, emergency medical technicians, or police officers. Medical facilities including nursing homes should have a plan for long-distance (over 100 km) evacuation, and the plan should be routinely reevaluated with full-scale exercises. In addition, hospital evacuation in disaster settings should be

    Horticulture therapy employs plants and gardening activities in therapeutic and rehabilitation activities and could be utilized to improve the quality of life of the worldwide aging population, possibly reducing costs for long-term, assisted living and dementia unit residents. Preliminary studies have reported the benefits of horticultural therapy and garden settings in reduction of pain, improvement in attention, lessening of stress, modulation of agitation, lowering of as needed medications, antipsychotics and reduction of falls. This is especially relevant for both the United States and the Republic of Korea since aging is occurring at an unprecedented rate, with Korea experiencing some of the world's greatest increases in elderly populations. In support of the role of nature as a therapeutic modality in geriatrics, most of the existing studies of garden settings have utilized views of nature or indoor plants with sparse studies employing therapeutic gardens and rehabilitation greenhouses. With few controlled clinical trials demonstrating the positive or negative effects of the use of garden settings for the rehabilitation of the aging populations, a more vigorous quantitative analysis of the benefits is long overdue. This literature review presents the data supporting future studies of the effects of natural settings for the long term care and rehabilitation of the elderly having the medical and mental health problems frequently occurring with aging.

  7. The fungus gardens of leaf-cutter ants undergo a distinct physiological transition during biomass degradation

    Leaf-cutter ants are dominant herbivores in ecosystems throughout the Neotropics. Rather than directly consuming the fresh foliar biomass they harvest, these ants use it to cultivate specialized fungus gardens. Although recent investigations have shed light on how plant biomass is degraded in fungus gardens, the cycling of nutrients that takes place in these specialized microbial ecosystems is still not well understood. Here, using metametabolomics and metaproteomics techniques, we examine the dynamics of nutrient turnover and biosynthesis in these gardens. Our results reveal that numerous free amino acids and sugars are depleted throughout the process of biomass degradation, indicating that easily accessible nutrients from plant material are readily consumed by microbes in these ecosystems. Accumulation of cellobiose and lignin derivatives near the end of the degradation process is consistent with previous findings of cellulases and laccases produced by Leucoagaricus gongylophorus, the fungus cultivated by leaf-cutter ants. Our results also suggest that ureides may be an important source of nitrogen in fungus gardens, especially during nitrogen-limiting conditions. No free arginine was detected in our metametabolomics experiments despite evidence that the host ants cannot produce this amino acid, suggesting that biosynthesis of this metabolite may be tightly regulated in the fungus garden. These results provide new insights into the dynamics of nutrient cycling that underlie this important ant-fungus symbiosis.

    To elucidate the impacts of nuclear plant accidents on neighboring medical centers, we investigated the operations of our hospital within the first 10 days of the Great East Japan Earthquake followed by the Fukushima Daiichi nuclear power plant accident. Data were extracted from medical records and hospital administrative records covering 11 to 20 March 2011. Factual information on the disaster was obtained from public access media. A total of 622 outpatients and 241 inpatients were treated. Outpatients included 43 injured, 6 with cardiopulmonary arrest, and 573 with chronic diseases. Among the 241 inpatients, 5 died, 137 were discharged, and the other 99 were transferred to other hospitals. No communication methods or medical or food supplies were available for 4 days after the earthquake. Hospital directors allowed employees to leave the hospital on day 4. All 39 temporary workers were evacuated immediately, and 71 of 239 full-time employees remained. These employees handled extra tasks besides patient care and patient transfer to other hospitals. Committed effective doses indicating the magnitude of health risks due to an intake of radioactive cesium into the human body were found to be minimal according to internal radiation exposure screening carried out from July to August 2011. After the disaster, hospitals located within the evacuation zone of a 30-km radius of the nuclear power plant were isolated. Maintenance of the health care system in such an event becomes difficult.

    2014-01-01

    Anesthesia of great apes is often necessary to conduct diagnostic analysis, provide therapeutics, facilitate surgical procedures, and enable transport and translocation for conservation purposes. Due to the stress of remote delivery injection of anesthetic agents, recent studies have focused on oral delivery and/or transmucosal absorption of preanesthetic and anesthetic agents. Maintenance of the airway and provision of oxygen is an important aspect of anesthesia in great ape species. The provision of analgesia is an important aspect of the anesthesia protocol for any procedure involving painful stimuli. Opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) are often administered alone, or in combination to provide multi-modal analgesia. There is increasing conservation management of in situ great ape populations, which has resulted in the development of field anesthesia techniques for free-living great apes for the purposes of translocation, reintroduction into the wild, and clinical interventions.

    Food access is a global issue, and for this reason, a wealth of studies are dedicated to understanding the location of food deserts and the benefits of urban gardens. However, few studies have linked these two strands of research together to analyze whether urban gardening activity may be a step forward in addressing issues of access for food desert residents. The Phoenix, Arizona metropolitan area is used as a case to demonstrate the utility of spatial optimization models for siting urban gardens near food deserts and on vacant land. The locations of urban gardens are derived from a list obtained from the Maricopa County Cooperative Extension office at the University of Arizona which were geo located and aggregated to Census tracts. Census tracts were then assigned to one of three categories: tracts that contain a garden, tracts that are immediately adjacent to a tract with a garden, and all other non-garden/non-adjacent census tracts. Analysis of variance is first used to ascertain whether there are statistical differences in the demographic, socio-economic, and land use profiles of these three categories of tracts. A maximal covering spatial optimization model is then used to identify potential locations for future gardening activities. A constraint of these models is that gardens be located on vacant land, which is a growing problem in rapidly urbanizing environments worldwide. The spatial analysis of garden locations reveals that they are centrally located in tracts with good food access. Thus, the current distribution of gardens does not provide an alternative food source to occupants of food deserts. The maximal covering spatial optimization model reveals that gardens could be sited in alternative locations to better serve food desert residents. In fact, 53 gardens may be located to cover 96.4% of all food deserts. This is an improvement over the current distribution of gardens where 68 active garden sites provide coverage to a scant 8.4% of food desert

    The potential contribution of allotment gardens to a healthy and active life-style is increasingly recognized, especially for elderly populations. However, few studies have empirically examined beneficial effects of allotment gardening. In the present study the health, well-being and physical activity of older and younger allotment gardeners was compared to that of controls without an allotment. A survey was conducted among 121 members of 12 allotment sites in the Netherlands and a control group of 63 respondents without an allotment garden living next to the home addresses of allotment gardeners. The survey included five self-reported health measures (perceived general health, acute health complaints, physical constraints, chronic illnesses, and consultations with GP), four self-reported well-being measures (stress, life satisfaction, loneliness, and social contacts with friends) and one measure assessing self-reported levels of physical activity in summer. Respondents were divided into a younger and older group at the median of 62 years which equals the average retirement age in the Netherlands. After adjusting for income, education level, gender, stressful life events, physical activity in winter, and access to a garden at home as covariates, both younger and older allotment gardeners reported higher levels of physical activity during the summer than neighbors in corresponding age categories. The impacts of allotment gardening on health and well-being were moderated by age. Allotment gardeners of 62 years and older scored significantly or marginally better on all measures of health and well-being than neighbors in the same age category. Health and well-being of younger allotment gardeners did not differ from younger neighbors. The greater health and well-being benefits of allotment gardening for older gardeners may be related to the finding that older allotment gardeners were more oriented towards gardening and being active, and less towards passive relaxation

    After the accident of the Fukushima Daiichi nuclear power plant due to the Great East Japan Earthquake in March 2011, the Japanese government issued a mandatory evacuation order for people living within a 20 km radius of the nuclear power plant. The aim of the current study was to investigate long-term outcomes of these patients and identify factors related to mortality. Patients who were evacuated from hospitals near the Fukushima Daiichi nuclear power plant to the Aizu Chuo Hospital from 15 to 26 March, 2011 were included in this study. The following data were collected from medical records: age, sex, activities of daily life, hospital they were admitted in at the time of earthquake, distance between the facility and the nuclear power plant, reasons of evacuation and number of transfers. The patient outcomes were collected from medical records and/or investigated on the telephone in January 2012. A total of 97 patients (28 men and 69 women) were transferred from 10 hospitals via ambulances or buses. No patients died or experienced exacerbation during transfer. Median age of the patients was 86 years. Of the total, 36 patients were not able to obey commands, 44 were bed-ridden and 61 were unable to sustain themselves via oral intake of food. Among 86 patients who were followed-up, 41 (48%) died at the end of 2011. Multiple-regression analysis showed that non-oral intake [Hazard Ratio (HR): 6.07, 95% Confidence interval (CI): 1.94-19.0] and male sex [HR: 8.35, 95% CI: 2.14-32.5] had significant impact on mortality. This study found that 48% of the evacuated patients died 9 months after the earthquake and they had significantly higher mortality rate than the nursing home residents. Non-oral intake and male sex had significant impact on mortality. These patients should be considered as especially vulnerable in case of hospital evacuation.

    Results of the work done at the National Botanic Garden, Lucknow, on radiation induced somatic mutations in roses are reported. Bud-wood of various rose cultivars was exposed to radiation doses ranging from 2 to 8 kR of gamma rays. In general, irradiation delayed sprouting of rose buds and decreased bud-take. Budded plants after irradiation showed decrease in survival and height of plants and also decrease in percentage of essential oil in flowers. Various abnormalities in shape, size and colour of leaves were observed. These effects were enhanced by increase in radiation dose. An explanation of these effects is attempted on the basis of injurious biochemical and cytological changes induced in plant cells by radiation. Somatic mutants isolated and stabilised are described.

    The human-health risk posed by gardening near a legacy mine and smelter in an arsenic-endemic region of Arizona was characterized in this study. Residential soils were used in a greenhouse study to grow common vegetables, and local residents, after training, collected soil, water, and vegetables samples from their home gardens. Concentrations of arsenic measured in water, soil, and vegetable samples were used in conjunction with reported US intake rates to calculate the daily dose, Incremental Excess Lifetime Cancer Risk (IELCR), and Hazard Quotient for arsenic. Relative arsenic intake dose decreased in order: water>garden soils>homegrown vegetables, and on average, each accounted for 77, 16, and 7% of a residential gardener's daily arsenic intake dose. The IELCR ranges for vegetables, garden soils, and water were 10(-8) to 10(-4), 10(-6) to 10(-4), and 10(-5) to 10(-2), respectively. All vegetables (greenhouse and home garden) were grouped by scientific family, and the risk posed decreased as: Asteraceae≫Fabaceae>Amaranthaceae>Liliaceae>Brassicaceae>Solanaceae≫Cucurbitaceae. Correlations observed between concentrations of arsenic in vegetables and soils were used to estimate a maximum allowable level of arsenic in soil to limit the excess cancer risk to 10(-6). The estimated values are 1.56 mg kg(-1), 5.39 mg kg(-1), 11.6 mg kg(-1) and 12.4 mg kg(-1) for the Asteraceae, Brassicaceae, Fabaceae, and Amaranthaceae families, respectively. It is recommended that home gardeners: sample their private wells annually, test their soils prior to gardening, and, if necessary, modify their gardening behavior to reduce incidental soil ingestion. This study highlights the importance of site-specific risk assessment, and the need for species-specific planting guidelines for communities. Copyright © 2013 Elsevier B.V. All rights reserved.

    1988-01-01

    In 1979, before the primary Zn smelter at Palmerton was closed due to excessive Zn and Cd emissions and change in the price of Zn, we were contacted by a local veterinarian regarding death of foals (young horses) on farms near the smelter. To examine whether Zn or Cd contamination of forage or soils could be providing potentially toxic levels of Zn or other elements in the diets of foals, we measured metals in forages, soils, and feces of grazing livestock on two farms near Palmerton. The farms were about 2.5 and about 10 km northeast of the East stack. Soils, forages, and feces were greatly increased in Zn and Cd. Soil, forage, and fecal Zn were near 1000 mg/kg and Cd, 10-20 mg/kg at farm A (2.5 km) compared to normal background levels of 43 mg Zn and 0.2 mg Cd/kg, respectively. Liver and kidney of cattle raised on Farm A were increased in Zn and Cd, indicating that at least part of the Zn and Cd in smelter contaminated forages was bioavailable. During the farm sampling, we obtained soil from one garden in Palmerton within 200 m of the primary (West) smelter. The Borough surrounds the smelter facility in a valley. Because soil Cd was near 100 mg/kg, we sampled garden soils and vegetables from over 40 gardens in 6 randomly selected blocks and in rural areas at different distances from the smelter during September, 1980. All homes were contacted on each sampled block. Nearly all homes had some garden, while at least 2 appeared to grow over 50% of their annual vegetable and potato consumption. Palmerton garden soils averaged 76 mg Cd/kg and 5830 mg Zn/kg. Gardeners had been taught to add limestone and organic fertilizers to counteract yield reduction and chlorosis due to the excessive soil Zn. Gardens with over 5000 mg Zn/kg were nearly allover pH 7, and many were calcareous. Because the smelter had not yet ceased operations in 1980, crops could have been polluted by aerosol Zn and Cd emitted by the smelter. Crop Zn and Cd were extremely high, about 100 times normal

    The Fukushima Pregnancy and Birth Survey was launched to monitor pregnant mothers' health after the Great East Japan Earthquake and Fukushima Daiichi Nuclear Power Plant (NPP) accident. Several lines of investigations have indicated that a disaster impacts maternal mental health with childbirth. However, there is no research regarding mental health of mothers with fetal loss after a disaster. In this report, we focus on those women immediately after the Great East Japan Earthquake and Fukushima NPP accident and discuss their support needs. Data regarding 61 miscarriages, 5 abortions, and 22 stillbirths were analyzed among the women who were pregnant at the time of the accident in the present study. We used a two-item case-finding instrument for depression screening, and compared the childbirth group with the fetal loss groups. We also analyzed mothers' opinions written as free-form text. Among the three fetal loss groups, the proportion of positive depression screens was significantly higher in the miscarriage and stillbirth group than in the childbirth group. Mothers' opinions were grouped into six categories, with pregnancy-related items being most common, especially in the miscarriage and stillbirth groups. A higher proportion of Fukushima mothers with fetal loss, especially those with miscarriage and stillbirth, had depressive symptoms compared to those who experienced childbirth. Health care providers need to pay close attention to this vulnerable group and respond to their concerns regarding the effects on their fertility.

    The objective of this study is to trace short-term changes in mood and heart function in elderly individuals in response to exposure to different landscaped spaces. Nineteen elderly but cognitively intact residents of an assisted living facility participated in the study. They were exposed to three landscaped spaces: a Japanese style garden, an herb garden, and a simple landscaped area planted with a single tree. To assess the effect of different landscaped spaces on older adults, individuals were monitored for mood and cardiac function in response to short exposures to spaces. Mood state was assessed using Profile of Mood States (POMS) before and after viewing the spaces. Cardiac output was assessed using a portable electrocardiograph monitor before and during the viewing. We found that the structured gardens evoked greater responses in all outcome measures. Scores on the POMS improved after observation of the two organized gardens compared to responses to the simple landscaped space with a single tree. During the observation period, heart rate was significantly lower in the Japanese garden than in the other environments, and sympathetic function was significantly lower as well. We conclude that exposure to organized gardens can affect both the mood and cardiac physiology of elderly individuals. Our data further suggest that these effects can differ depending on the types of landscape to which an individual is exposed.

    Using a participatory research framework, researchers at the Centre for Rural Health, University of Tasmania, explored the potential of Community Gardens to function as comprehensive primary healthcare (CPHC) environments. Community gardeners, coordinators, volunteers and Neighbourhood House coordinators discussed their understandings of the health benefits of community gardens, how they contribute to broad CPHC aims and the barriers and enablers to greater CPHC contributions in the future. This research identifies therapeutic features of Community Gardens and explores the correlations between these and CPHC. It is concluded that there are strong synergies between the aims and activities of Community Gardens and CPHC. To augment the therapeutic capacity of these sites requires adequate resourcing and skill development, suitable design, funding and policy support, along with innovative partnerships with health professionals.

    Compared with traditional rehabilitation, gardening has been viewed as a more occupation-based intervention to help patients improve functional performance. However, there is still a need for evidence-based research into what factors interact to create the beneficial effects of gardening for people who have sustained a cerebral vascular accident (CVA). To explore how plant, gender, and the time after stroke onset influenced improvements in the quality of life of patients in a gardening program. One treatment of tending short-term plants, and another treatment of tending long-term plants were compared. Quality of life improvement was evaluated according to three factors: plant, gender, and the time after stroke onset. The data were analyzed with 2k replicated factorial designs. The 2k factorial design with replication indicated significant effects on both the social role and the family role. For the social role, the interaction of plant and gender difference was significant. For the family role, the significant effects were found on interaction of plant with both gender and the time after stroke onset. Tending plants with different life cycles has varied effects on the quality of life of people who have sustained a CVA. Factors related to gender and the time after stroke onset influenced role competency in this sample.

    2017-12-01

    Full Text Available Impacts of global climate change, habitat loss, and other environmental changes on the world's biota and peoples continue to increase, especially on islands and in high elevation areas. Just as floristic diversity is affected by environmental change, so too are cultural and linguistic diversity. Of the approximately 7000 extant languages in the world, fully 50% are considered to be at risk of extinction, which is considerably higher than most estimates of extinction risks to plants and animals. To maintain the integrity of plant life, it is not enough for botanic gardens to consider solely the effects of environmental change on plants within the context of major conservation strategies such as the Global Strategy for Plant Conservation and the Convention on Biological Diversity. Rather, botanic gardens should actively engage in understanding and communicating the broader impacts of environmental change to biological and cultural diversity.

The total project involves halls for cultural and social activities, church office, kitchen, as well as secondary annexes; also a Sunday school, with a nursery and schoolrooms for children of various ages. Outdoors, there is an ample parking space, where the motorcars—the Americans' second home—can be orientated facing the altar. Thus their occupants can follow the Mass visually, when the large sliding doors are opened, at the beginning of the service; then, at the end of the service these doors are slowly and solemnly closed. Furthermore, these automobile owners can also follow the service by listening to it through individual loudspeakers, which are supplied to each vehicle. Once more Mr. Neutra has designed thinking of man as a human being, and finding room for the women the children and the men who go to church not only inside the church, but also within the more intimate atmosphere of their own cars. He feels that religion must be something living, evolving with the times. The modern congregation is not that of the primitive Christians, living in their sombre catacombs, nor is it similar to the picturesque and intense believers of the Middle Ages. He has therefore created a happy solution, very apt to the anxious and hopeful people of today.La iglesia de la Comunidad de Garden Grove ocupa una superficie de 1.067,45 m2, y dispone de 672 asientos y capacidad total para 1.000 feligreses.

    Full Text Available Culture and identity in a society can be represented in the architecture and the meanings intertwined with it. In this sense, the architecture and design are the interface for transferring meaning and identity to the nation and future generations. Persian gardens have been evolved through the history of Persian Empire in regard to the culture and beliefs of the society. This paper aims to investigate the patterns of design and architecture in Persian gardens and the meanings intertwined with their patterns and significant elements such as water and trees. Persian gardens are not only about geometries and shapes; but also manifest different design elements, each representing a specific symbol and its significance among the society. This paper seeks to explore Persian gardens in terms of their geometric structure, irrigation system, network construction and pavilions alongside design qualities such as hierarchy, symmetry, centrality, rhythm and harmony. In the second stage, the paper investigates the fundamental symbols and their philosophy in the creation of Persian gardens and in relation to the architecture and design.

    We chose five easily propagated garden plants previously shown to be attractive to mosquitoes, ants or other insects and tested them for attractiveness to Culex pipiens and Aedes aegypti. Long term imbibition was tested by survival on each plant species. Both mosquito species survived best on Impatiens walleriana, the common garden impatiens, followed by Asclepias curassavica, Campsis radicans and Passiflora edulis, which sponsored survival as well as the 10% sucrose control. Immediate preference for imbibition was tested with nectar dyed in situ on each plant. In addition, competition studies were performed with one dyed plant species in the presence of five undyed plant species to simulate a garden setting. In both preference studies I. walleriana proved superior. Nectar from all plants was then screened for nectar protein content by SDS-PAGE, with great variability being found between species, but with I. walleriana producing the highest levels. The data suggest that I. walleriana may have value as a model plant for subsequent studies exploring nectar delivery of transgenic mosquitocidal proteins. Copyright © 2015 Elsevier B.V.

    Full Text Available Community service work, volunteerism and mentoring have recently become popular topics of research as effective methods in improving self-esteem and civic responsibility. In the current study we explored the relationship between participation in a community service gardening program and ethnocentrism. We hypothesised that an inverse correlation would emerge where students who participated in a community service-gardening program would increase their perceptions of the importance of community service work and decrease their scores in ethnocentrism. Results of the paired samples t-test strongly support the hypothesis that community service gardening work significantly reduces reports of ethnocentrism: t(10 = -2.52, (p < .03 for community college students. The ramifications of the study and ramifications for future research are offered.

    Full Text Available Acute nontraumatic exertional rhabdomyolysis may arise when the energy supply to muscle is insufficient to meet demands, particularly in physically untrained individuals. We report on a psychiatric patient who developed large bruises and hemorrhagic blisters on both hands and arms, rhabdomyolysis of both forearm muscles with a moderate compartment syndrome, and consecutive acute renal failure following excessive work in the garden. Although specifically asked, the patient denied any hard physical work or gardening, and heteroanamnestic data were not available. The diagnosis of rhabdomyolysis was easy to establish, but until reliable anamnestic data were obtained, the etiology remained uncertain. Four days after arrival, the patient recalled working hard in the garden. The etiology of rhabdomyolysis was finally reached, and the importance of anamnestic data was once more confirmed.

Everything takes place with the participation of boys, girls, fathers and mothers of the Colegio Ateneo nursery school of Tezoyuca, State of Mexico. Childrens' participation has helpedspread the word about the experience and little by little, the strategy has spread to other educational spaces. The school garden has become a space to raise ecological and environmental awareness that is strengthened with daily activities and specific activities that are implemented. The school garden is based on a series of philosophical principles that help reflect upon our learning-doing; in methodological terms, its implementation is based on ethics and on the principles of permaculture.

  6. Reflexions on Urban Gardening in Germany

    Directory of Open Access Journals (Sweden)

    Evelyn Gustedt

    2016-04-01

    Full Text Available This article reflects on traditional and contemporary gardening movements in Germany. The focus is on forms of gardening, that take place in spaces subject to land lease agreements and similar forms of tenancy or of illegal land take or squatting. The author examines various definitions taking into account the variety of practices, the development of urban gardening over time, and the respective backgrounds or values that users relate to such gardening activities. The examination of definitions led to the drawing up of a timeline of traditional and contemporary gardening movements in Germany and to the tentative approaching of this issue from a semantic perspective. The latter is due to the usage of many different terms mostly as yet undefined in a legal sense. Translation into English or, most likely, to any other language, further blurs the common understanding of the terms used. The author concludes with some considerations on these gardening movements in relation to urban sustainable developments. A presentation at the 5th Rencontres Internationals de Reims on Sustainability Studies, dedicated to Urban Agriculture – Fostering the Urban-Rural Continuum, which took place in October 2015 in Reims/France was the starting point of this article. The basis of this article is a literature review, nourished to a certain extent by observations randomly made over many years and complemented through talks with competent young colleagues. Special thanks go to Martin Sondermann, Leibniz University Hannover, who shared his research experience in various discussions with the author, as well as to Friederike Stelter, internship student at the author’s place of work, who gave highly appreciated support to the preparation of the presentation.

    Although urban community gardening can offer health, social, environmental, and economic benefits, these benefits must be weighed against the potential health risks stemming from exposure to contaminants such as heavy metals and organic chemicals that may be present in urban soils. Individuals who garden at or eat food grown in contaminated urban garden sites may be at risk of exposure to such contaminants. Gardeners may be unaware of these risks and how to manage them. We used a mixed quantitative/qualitative research approach to characterize urban community gardeners' knowledge and perceptions of risks related to soil contaminant exposure. We conducted surveys with 70 gardeners from 15 community gardens in Baltimore, Maryland, and semi-structured interviews with 18 key informants knowledgeable about community gardening and soil contamination in Baltimore. We identified a range of factors, challenges, and needs related to Baltimore community gardeners' perceptions of risk related to soil contamination, including low levels of concern and inconsistent levels of knowledge about heavy metal and organic chemical contaminants, barriers to investigating a garden site's history and conducting soil tests, limited knowledge of best practices for reducing exposure, and a need for clear and concise information on how best to prevent and manage soil contamination. Key informants discussed various strategies for developing and disseminating educational materials to gardeners. For some challenges, such as barriers to conducting site history and soil tests, some informants recommended city-wide interventions that bypass the need for gardener knowledge altogether.

    This dissertation illustrates how a children's community garden, designed specifically to promote intergenerational, multi-sociocultural relationships, is an "ideological environment" linking individuals and their community and connecting people with nature, in order to promote feelings of belonging, social connection, and encourage a sense of stewardship and identification with the environment (Bakhtin, 1978). By spending time in a community garden, responding to the natural ecosystems which exist on this land, and reflecting, through image and story about our childhood experience, the participants and I engaged in the dialogic process of what Thomashow (1996) refers to as "doing ecological identity work." Throughout this study I question how our past experiences with nature in ideological environments shape our ecological epistemologies, and how the dialogic process of becoming a gardener within the context of a community garden shapes a person's ecological identity. To frame this exploration of ecological identity work as a dialogic process and its role in the development of an ecological identity, I draw from sociocultural theory (Holland, et al., 1998), Bakhtin's theory of dialogism, and ecological identity studies (Clayton and Opotow, 2003; Cobb, 1993; Orr, 1994, 2006; Sobel, 1996, 2008; Thomashow, 1996). A large body of scholarly writing done by environmental researchers is devoted to examining and describing how adults, who self-identify as environmentalists, developed an ecological worldview. However, only a fraction of research is devoted to theorizing how children develop an environmental epistemology. In this study, I focus on how community gardens are dialogic spaces that provide a place for elementary-aged children to "experience" the discourse of gardening. Here, I describe the discourses that shape the garden and describe how gardeners, as a result of their collaborative experiences between human and non-human actors, take up social and dialogical

  9. Gardens, knowledge and the sciences in the early modern period

    CERN Document Server

    Remmert, Volker; Wolschke-Bulmahn, Joachim

    2016-01-01

    This volume focuses on the outstanding contributions made by botany and the mathematical sciences to the genesis and development of early modern garden art and garden culture. The many facets of the mathematical sciences and botany point to the increasingly “scientific” approach that was being adopted in and applied to garden art and garden culture in the early modern period. This development was deeply embedded in the philosophical, religious, political, cultural and social contexts, running parallel to the beginning of processes of scientization so characteristic for modern European history. This volume strikingly shows how these various developments are intertwined in gardens for various purposes.

  10. Gray and Green Revisited: A Multidisciplinary Perspective of Gardens, Gardening, and the Aging Process

    Wright, Scott D.; Wadsworth, Amy Maida

    2014-01-01

    Over fourteen years ago, the concept of “gray and green” was first introduced by Wright and Lund (2000) to represent a new awareness and a call for increased scholarship at the intersection of environmental issues and the aging process. This review paper revisits that concept with a fresh perspective on the specific role of gardens and gardening in the aging experience. As example, gardening is one of the most popular home-based leisure activities in the US and represents an important activity in the lives of older adults in a variety of residential settings. Yet, there has been a lack of any comprehensive and multidisciplinary (science and humanities) examination of the nexus between gardening and the aging experience, and in particular with research connections to stewardship and caring. In this paper, we review contemporary articles demonstrating the multidisciplinarity of gardening and the aging process. First, we will focus on the beneficial psychological effects resulting from the cultivation of caring, including personal contentment and artistic expression. Second, we will focus on stewardship and how gardening increases health, community awareness, and a connection to future generations. On the surface, this may demonstrate a separation between the humanities and science, but we will clarify a symbiotic relationship between the two disciplines in our conclusion. PMID:24734179

    A new park in Beijing is a unique project implemented at a former city waste area. The project was started in 2010. In 2013, the park was opened for its first visitors. Today, it has 69 gardens representing different Chinese provinces and major cities, as well as other countries whose designers wanted to demonstrate their class. The created gardens of 1-2 to 10-12 hectares represent both traditional styles of Chinese gardens and the latest trends in the field of garden art. The Museum of Chinese Gardens and Landscape Architecture (MCGALA is a part of the park’s vast territory of 513 hectares. The park also has the necessary infrastructure for its visitors with disabilities. Today, it has become a home for many educational institutions training specialists in the field of landscape design, as well as for the employees of the country’s parks, agronomists and gardeners.

  13. ECONOMIC PERFORMANCE OF COMMUNITY GARDEN IN ZIMBABWE

    Full Text Available Zimbabwe has experienced an unprecedented decline of nearly all human development indicators for the past ten years. Despite the introduction of community gardens in drought-prone areas of Zimbabwe, poverty persists amongst the vulnerable groups. The potential to improve household, community and national food and nutrition security through garden activities is high if issues of water availability cost and availability of inputs, marketing and farmer empowerment can be addressed. This paper seeks to assess the community garden's cost structure to sales volume and profitability and the land use efficiency. Primary data were collected through structured questionnaire. A two stage sampling techniques was used to select respondents. The study was conducted in Zaka district. Three major crops namely tomatoes, covo and onion were chosen for the study basing on size of land under that particular crop. Cost-Volume-Profit analysis employed for analysis of cost structure to sales volume and profitability. Land use efficiency was also employed to measure the ratio yield per acre of farm to average yield of locality. The results showed that although the farmers are able to break even the margin of safety is small especially for cove and onion. The study recommends farmers to increase the size of acreage under onion production whilst reduce acreage under production of covo. Farmers should adopt technology that would improve land use efficiency of onion. There is a need for the intervention by the Government and other stakeholders to improve the profitability and efficiency of the community gardeners. Stakeholders' collaboration especially, in terms of farmer training which can improve garden activities as participants lack knowhow.

    In many regions of Iran, crops are irrigated with municipal and industrial wastewater that contain a variety of metals. The purpose of this study was to simulate the level of metals that may be presented to plants over a growing season in a controlled laboratory setting. Cadmium, lead, arsenic, chromium, mercury, nickel, copper, zinc, and selenium were applied to plants at the high rate of 200 g metal/ha/wk. The following plants were examined for metal accumulation and effects on yield: garden cress (Lipidium sativum), leek (Allium porrum L.), basil (Ocimum basilicum L.), mint (Mentha arvensis L.), onion (Allium capa L.), radish (Raphanus sativus L.), and tarragon (Artemisia draculus L.). All plants showed significant uptake of all metals when compared to control (p=0.05), and growth was significantly reduced (p=0.05). Cadmium and chromium levels of 85±7.4 and 47.6±8.9 μg/g); selenium levels were highest in tarragon (16.5±5.8 μg/g). Zinc levels were similar (p=0.05) in all species tested, as were mercury and lead. The remaining metals (nickel and copper) showed significant differences in uptake, depending on plant species.

    The growth of roots of plants can damage roof garden components, such as pavements. This paper developed a test method for evaluating the resistance of pavement used in roof gardens to damage from a thickening growth of roots. The study assessed the behaviour of plant roots and evaluated the force of root growth subjected to hypertrophy. A system to measure the enlargement force of roots was designed and used for measurements over a period of 8 months on a cherry blossom of 21 years growth. The enlargement force was approximately 440 N/cm. A mechanical simulated root was designed and used to carry out experimental tests on asphalt pavements. The tests results demonstrated the viability of simulated root for evaluation of root resistances in pavements and various components of roof gardens.

    Urban streams are an integral part of the municipal water cycle and provide a point of discharge for wastewater treatment plant (WWTP) effluents, allowing additional attenuation through dilution and transformation processes, as well as a conduit for transporting contaminants to downstream water supplies. Domestic and commercial activities dispose of wastes down-the-drain, resulting in wastewater containing complex chemical mixtures that are only partially removed during treatment. A key issue associated with WWTP effluent discharge into streams is the potential to cause endocrine disruption in fish. This study provides a long-term (1999-2009) evaluation of the occurrence of alkylphenolic endocrine disrupting chemicals (EDCs) and other contaminants discharged from WWTPs into streams in the Great Lakes and Upper Mississippi River Regions (Indiana, Illinois, Michigan, Minnesota, and Ohio). The Greater Metropolitan Chicago Area Waterways, Illinois, were evaluated to determine contaminant concentrations in the major WWTP effluents and receiving streams, and assess the behavior of EDCs from their sources within the sewer collection system, through the major treatment unit processes at a WWTP, to their persistence and transport in the receiving stream. Water samples were analyzed for alkylphenolic EDCs and other contaminants, including 4-nonylphenol (NP), 4-nonylphenolpolyethoxylates (NPEO), 4-nonylphenolethoxycarboxylic acids (NPEC), 4-tert-octylphenol (OP), 4-tert-octylphenolpolyethoxylates (OPEO), bisphenol A, triclosan, ethylenediaminetetraacetic acid (EDTA), and trace elements. All of the compounds were detected in all of the WWTP effluents, with EDTA and NPEC having the greatest concentrations. The compounds also were detected in the WWTP effluent dominated rivers. Multiple fish species were collected from river and lake sites and analyzed for NP, NPEO, NPEC, OP, and OPEO. Whole-body fish tissue analysis indicated widespread occurrence of alkylphenolic compounds

    This work analyses the carbon dioxide (CO2) capture system operation within the Electric Reliability Council of Texas (ERCOT) and Great Britain (GB) electric grids using a previously developed first-order hourly electricity dispatch and pricing model. The grids are compared in their 2006 configuration with the addition of coal-based CO2 capture retrofits and emissions penalties from 0 to 100 US dollars per metric ton of CO2 (USD/tCO2). CO2 capture flexibility is investigated by comparing inflexible CO2 capture systems to flexible ones that can choose between full- and zero-load CO2 capture depending on which operating mode has lower costs or higher profits. Comparing these two grids is interesting because they have similar installed capacity and peak demand, and both are isolated electricity systems with competitive wholesale electricity markets. However, differences in capacity mix, demand patterns, and fuel markets produce diverging behaviours of CO2 capture at coal-fired power plants. Coal-fired facilities are primarily base load in ERCOT for a large range of CO2 prices but are comparably later in the dispatch order in GB and consequently often supply intermediate load. As a result, the ability to capture CO2 is more important for ensuring dispatch of coal-fired facilities in GB than in ERCOT when CO2 prices are high. In GB, higher overall coal prices mean that CO2 prices must be slightly higher than in ERCOT before the emissions savings of CO2 capture offset capture energy costs. However, once CO2 capture is economical, operating CO2 capture on half the coal fleet in each grid achieves greater emissions reductions in GB because the total coal-based capacity is 6 GW greater than in ERCOT. The market characteristics studied suggest greater opportunity for flexible CO2 capture to improve operating profits in ERCOT, but profit improvements can be offset by a flexibility cost penalty.

    2012-12-01

    The availability of soil nutrients and heavy metals in urban community gardens can influence health of crops and participants. Interactions between garden history, management, and soils are understudied in cities. In July 2011, we collected soil samples from 45 plots at 6 Los Angeles community gardens. For comparison, 3 samples were collected from uncultivated garden soils and 3 more from outside soils. Samples were then tested for major nutrients- Nitrogen(N), Potassium (K), and Phosphorous (P)- and organic matter (SOM). We also measured concentrations of 29 metals in 3 gardens using Inductively Coupled Plasma- Atomic Emission Spectroscopy. Potassium and phosphorus exceeded optimum levels in all plots, with some over twice the maximum recommended levels. Over-fertilized soils may contribute to local watershed pollution and crop micronutrient deficiencies. Low soil SOM was observed in gardens in impoverished neighborhoods, possibly due to low quality amendments. Our metals analysis showed dangerous levels of lead (Pb)-- up to 1700 ppm in outside soils and 150 ppm in garden soils-- near older gardens, indicating lead deposition legacies. California lead safety standards indicate that children should not play near soils with Pb above 200 ppm, indicating need for long term monitoring of lead contaminated gardens. Arsenic (As) levels exceeded federal risk levels (0.3 ppm) and average CA background levels (2 ppm) in all areas, with some gardens exceeding 10 ppm. Heavy metal legacies in gardens may pose risks to participants with prolonged exposure and remediation of soils may be necessary.

    To predict a risk to gardeners not wearing protective gloves, the dermal absorption of three active insecticides was assessed in vitro using porcine ear-skin simulating 1-h handling of diluted plant protection products. Acetamiprid and Pirimicarb were found in the receptor fluid immediately after 1-h skin exposure, whereas Chlorpyrifos-methyl absorbed in the skin was not released into the receptor fluid even after 23 hours. The Estimated Gardener Exposure Level (EGEL) at 23 hours after 1-h exposure for two worst-case scenarios (i) non-gloved hands; (ii) non-gloved hands/uncovered forearms, was (i) 0.002, 0.042, and 0.057; (ii) 0.006, 0.101, and 0.135 mg/kg bw/day for Acetamiprid, Pirimicarb, and Chlorpyrifos-methyl, respectively, although the systemically available Chlorpyrifos-methyl amount, due to retention in the skin, is probably lower than determined. The Gardener Exposure Risk (GER), as a ratio of Acceptable Operator Exposure Level (databased values) to EGEL, for Acetamiprid was (i) 35 and 12-fold higher than the limit 1, so the risk via the skin is assumed to be low.

    Urbanization is a major threat to arthropod biodiversity and abundance due to reduction and loss of suitable natural habitat. Green spaces and small-scale agricultural areas may provide habitat and resources for arthropods within densely developed cities. We studied spider activity density (a measure of both abundance and degree of movement) and diversity in urban gardens in Santa Cruz, Santa Clara, and Monterey counties in central California, USA. We sampled for spiders with pitfall traps and sampled 38 local site characteristics for 5 mo in 19 garden sites to determine the relative importance of individual local factors. We also analyzed 16 landscape variables at 500-m and 1-km buffers surrounding each garden to determine the significance of landscape factors. We identified individuals from the most common families to species and identified individuals from other families to morphospecies. Species from the families Lycosidae and Gnaphosidae composed 81% of total adult spider individuals. Most of the significant factors that correlated with spider activity density and richness were local rather than landscape factors. Spider activity density and richness increased with mulch cover and flowering plant species, and decreased with bare soil. Thus, changes in local garden management have the potential to promote diversity of functionally important spiders in urban environments. © The Authors 2015.

    Full Text Available Indonesia, being part of the center of origin of bananas (Musaceae, has a large number diversity of bananas both wild seeded species and edible seedless cultivated varieties. Inventory of wild Musa species in Purwodadi Botanic Garden has been conducted through compiling data records from PBG’s Registration section, field inspection and observation to living collections in the garden, herbarium specimens and literature studies. The results show that total 17 wild Musa accessions has been recorded planted in Purwodadi Botanic Garden since 1990 until 2012; comprises of 8 Musa acuminata sub species, 2 Musa balbisiana forms, 1 Musa ornata, 1 Musa troglodytarum, 1 Musa borneensis and 4 unidentified species Musa spp.; but only 8 living accessions remained in 2012. Morphotaxonomic review of those 8 wild Musa accessions remained will be discussed in this paper including their geographical distributions. According to its differentiated morphological characteristics observations, it is known that there are three accessions were resembled cultivars and one unidentified species have been determined its species level, so that their registration identity needs to be revised. It is important next to prioritize ex-situ conservation of wild Musa species not yet collected in Purwodadi Botanic Garden especially from Eastern Indonesia.

    1991-01-01

    Soil heating using electricity, hot water and air has been studied within Nordic countries as a way to extend the growing season in spring. The methods have not found general acceptance in practical outdoor garden production in Nordic countries, except in Iceland. The main reason for this may be the fairly high investment costs, lack of know-how, and the above-normal risks both at the cultivation stage and in marketing of the harvest. Two thirds of the respondents (177 persons) were prepared to accept the soil heating on outdoor garden production by electrical cables if it is profitable. Only one fifth of the respondents thought that it would be wasting of natural resources, and that plant protection by chemicals should be cut down in the future or to keep their use at the present level. The respondents believed that more efforts should be made in marketing of the garden products by improving the product quality, purity and aroma, because these are the most important sales promotion factors. Two thirds thought that the Finnish garden production sector would retain it's present status or improve it in the future. Organic farming and greening were believed to possess the best prerequisites for surviving the increasingly tough competition of the non-restricted European markets. Under-glass cultivation and fruit orchards in Finland were believed to run into difficulties.

    Researchers have established the benefits of school gardens on students' academic achievement, dietary outcomes, physical activity, and psychosocial skills, yet limited research has been conducted about how school gardens become institutionalized and sustained. Our aim was to develop a tool that captures how gardens are effectively established, integrated, and sustained in schools. We conducted a sequential, exploratory, mixed-methods study. Participants were identified with the help of Grow To Learn, the organization coordinating the New York City school garden initiative, and recruited via e-mail. A stratified, purposeful sample of 21 New York City elementary and middle schools participated in this study throughout the 2013/2014 school year. The sample was stratified in their garden budgets and purposeful in that each of the schools' gardens were determined to be well integrated and sustained. The processes and strategies used by school gardeners to establish well-integrated school gardens were assessed via data collected from surveys, interviews, observations, and concept mapping. Descriptive statistics as well as multidimensional scaling and hierarchical cluster analysis were used to examine the survey and concept mapping data. Qualitative data analysis consisted of thematic coding, pattern matching, explanation building and cross-case synthesis. Nineteen components within four domains of school garden integration were found through the mixed-methods concept mapping analysis. When the analyses of other data were combined, relationships between domains and components emerged. These data resulted in the development of the GREEN (Garden Resources, Education, and Environment Nexus) Tool. When schools with integrated and sustained gardens were studied, patterns emerged about how gardeners achieve institutionalization through different combinations of critical components. These patterns are best described by the GREEN Tool, the first framework to identify how to

    Recent increasing concerns over the effects of climate change has prompted much debate into the issue of long term sustainability. An investigation was conducted into the feasibility of an off-grid housing unit, particularly in an Australian context. A pilot scale 3m × 2m off-grid housing unit was constructed. Forecasts for water requirements as well as an investigation into rainwater harvesting and greywater recycling was conducted. A multi-container plant and sand biological filter was constructed and filtration abilities investigated. The system met NSW government water reuse standards in terms of suspended solids and pH, achieving total suspended solid removal efficiency of up to 99%.

    The effect of remediation using three EDTA doses (10, 30, 60 mmol kg −1 ) on soil functioning was assessed using column experiment and Brassica rapa. Soil washing removed up to 77, 29 and 72% of metals from soil contaminated with 1378, 578 and 8.5 mg kg −1 of Pb, Zn and Cd, respectively. Sequential extraction indicated removal from the carbonate soil fraction. Metal oral-accessibility from the stomach phase was reduced by up to 75 and from the small intestine by up to 79% (Pb). Part of metals (up to 0.8% Cd) was lost due to leaching from columns. Remediation reduced toxic metal soil-root transfer by up to 61% but did not prevent metal accumulation in leaves. The fitness of plants grown on EDTA washed soils (gas exchange, fluorescence) was not compromised. Remediation initially reduced the soil DNA content (up to 29%, 30 mmol kg −1 EDTA) and changed the structure of microbial population. -- Highlights: ► Toxic metals contaminated garden soil was remediated in a pilot-scale. ► EDTA washing reduced soil Pb, Zn and Cd content and bioavailability. ► Remediated soil preserved the function of plant and microbial substrate. ► Remediation didn't prevent the accumulation of toxic metals in the test plant. -- EDTA soil washing effectively removed toxic metals and reduced their transfer from the soil to plant roots but did not prevent their accumulation in leaves

    The use of TLD method to measure exposure dose rate in 60 Co garden is described. As compared with chemical dosimetry, the relative deviation of measurement would not exceed 10%. The good repeatability has been proved by comparing the measurements of different times and distances with correction of decay law and 1/1 2 law. Besides, the distribution of exposure dose rate was influenced by scattering of the living plants

  13. Community Gardens as Environmental Health Interventions: Benefits Versus Potential Risks.

    Al-Delaimy, W K; Webb, M

    2017-06-01

    The purpose of this paper was to summarize current findings on community gardens relevant to three specific areas of interest as follows: (1) health benefits, (2) garden interventions in developing versus developed countries, and (3) the concerns and risks of community gardening. Community gardens are a reemerging phenomenon in many low- and high-income urban neighborhoods to address the common risk factors of modern lifestyle. Community gardens are not limited to developed countries. They also exist in developing low-income countries but usually serve a different purpose of food security. Despite their benefits, community gardens can become a source of environmental toxicants from the soil of mostly empty lands that might have been contaminated by toxicants in the past. Therefore, caution should be taken about gardening practices and the types of foods to be grown on such soil if there was evidence of contamination. We present community gardens as additional solutions to the epidemic of chronic diseases in low-income urban communities and how it can have a positive physical, mental and social impact among participants. On balance, the benefits of engaging in community gardens are likely to outweigh the potential risk that can be remedied. Quantitative population studies are needed to provide evidence of the benefits and health impacts versus potential harms from community gardens.

    Full Text Available Urban gardening finds itself at a juncture – not only are crises caused and exacerbated by the industrial food system urgently demonstrating the need for more localised, sustainable, and democratically-determined food systems, but alternative food movements are increasingly negotiating crises of their own. Critical Foodscapes was a one-day conference part-funded by Warwick’s Institute of Advanced Study (IAS and the Food GRP. The conference was put together with the intention of bringing a ‘critical studies’ approach to the emerging research area of urban community food growing; namely, to put critical – but constructive – pressure on some of the assumptions which underlie current theory and practice of the various forms of urban food growing. This article offers some reflections on the conference itself as well as on the prospects for urban gardening more generally.

    2002-04-01

    Surveys of visitor and grower perception of live potted plant quality were conducted in various locations in a large public display garden. Canna lily, Canna x generalis L.H.Bailey, was used to examine effects of defoliation by Japanese beetle, Popillia japonica Newman, on public perception. Chrysanthemums, Chrysanthemum x morifolium Ramat., were used to identify visitor and grower tolerance to flower distortion caused by western flower thrips, Frankliniella occidentalis (Pergande), on single and multiple flowered plants. On average, the maximum amount of defoliation or flower distortion tolerated by any respondent was low (< or = 10% for canna and < or = 25% for chrysanthemum). The level of acceptable injury was influenced by factors intrinsic to both the respondents and the plants themselves. Tolerance to injury was negatively associated with the risk aversion of the respondents. Visitors were less tolerant of injury on plants they considered for purchase than those that they would view at the garden. Similarly, grower tolerance was lower than that of visitors because producing substandard plants could put their professional reputation at risk. Factors that distracted visitor attention (e.g., presence of flowers and higher levels of background injury) increased their tolerance to plant injury. Visitors tolerated greater levels of flower distortion on multiple flowering chrysanthemum than on those with single flowers. We suggest that tolerance to insect pests can be increased by designing plantings that distract viewers from injured plant parts.

    2014-12-01

    High concentrations of ground-level ozone cause health problems in humans and a number of negative effects on plants, from reduced yield for major agricultural crops to reduced amounts of carbon stored in trees. The Denver Metro/Colorado Front Range is exceeding the National Ambient Air Quality Standard for ozone on a regular basis in summer and the efforts to reduce the ozone levels are hampered by the presence of diverse pollution sources and complex meteorology in the region. To raise public awareness of air quality in the Colorado Front Range and to educate all age groups about ground-level ozone, two ozone bioindicator gardens were planted in Boulder in Spring 2014. The gardens contain ozone-sensitive plants that develop a characteristic ozone injury when exposed to high levels of ozone. The ozone gardens are providing the general public with a real-life demonstration of the negative effects of ozone pollution through observable plant damage. Additionally, the gardens are useful in teaching students how to collect and analyze real-world scientific data.

    To examine if gardening experience and enjoyment are associated with vegetable exposure, preferences, and consumption of vegetables among low-income third-grade children. Cross-sectional study design, using baseline data from the Texas! Grow! Eat! Go! Twenty-eight Title I elementary schools located in different counties in Texas. Third-grade students (n = 1,326, 42% Hispanic) MAIN OUTCOME MEASURES: Gardening experience, gardening enjoyment, vegetable exposure, preference, and consumption. Random-effects regression models, adjusted for age, sex, ethnicity, and body mass index percentile of child, estimated means and standard errors of vegetable consumption, exposure, and preference by levels of gardening experience and enjoyment. Wald χ 2 tests evaluated the significance of differences in means of outcomes across levels of gardening experience and enjoyment. Children with more gardening experience had greater vegetable exposure and higher vegetable preference and consumed more vegetables compared with children who reported less gardening experience. Those who reported that they enjoyed gardening had the highest levels of vegetable exposure, preference, and consumption. Garden-based interventions can have an important and positive effect on children's vegetable consumption by increasing exposure to fun gardening experiences.

    2014-01-01

    Refugees are a particularly vulnerable population who undergo nutrition transition as a result of forced migration. This paper explores how involvement in a community food garden supports African humanitarian migrant connectedness with their new country. A cross-sectional study of a purposive sample of African refugees participating in a campus-based community food garden was conducted. Semi-structured interviews were undertaken with twelve African humanitarian migrants who tended established garden plots within the garden. Interview data were thematically analysed revealing three factors which participants identified as important benefits in relation to community garden participation: land tenure, reconnecting with agri-culture, and community belonging. Community food gardens offer a tangible means for African refugees, and other vulnerable or marginalised populations, to build community and community connections. This is significant given the increasing recognition of the importance of social connectedness for wellbeing. PMID:25198684

    This article maps out existing research regarding the effectiveness of integrated teaching in school gardens, i.e. including the math, languages and science subjects with their related objectives and curricula in school garden teaching and vice versa. The article is based on a literature review...... that concludes that school gardens have a predominantly positive influence on students’ learning outcome. However, there are a few school garden programmes that have the same or even a less beneficial influence on students’ learning outcome than traditional teaching. Thus, school gardens do not have...... an unequivocally positive academic learning effect. The review extracts and discusses some of the factors that are consistently emphasized in the research literature as central to ensuring successful subject integration in school gardens. Taking these as a point of departure, it is concluded that developing...

  2. Smell and Anosmia in the Aesthetic Appreciation of Gardens

    2014-01-01

    Full Text Available In his Critique of the Power of Judgment, Kant defined the garden as a visual art and considered that smell plays no role in its aesthetic appreciation. If the Kantian thesis were right, then a person who has no sense of smell (who suffers from anosmia would not be impaired in his or her aesthetic appreciation of gardens. At the same time, a visually impaired person could not appreciate the beauty of gardens, although he or she could perceive them through hearing, smell, taste, and touch. In this paper I discuss the role of smell and anosmia in the aesthetic appreciation of gardens. I accept the Kantian idea that the appreciation of a garden is the appreciation of its form, but I also defend that, at least in some cases, smell can belong to the form of gardens and, consequently, the ability or inability to smell influences their aesthetic appreciation.

  4. Leaf endophyte load influences fungal garden development in leaf-cutting ants

    Van Bael Sunshine A

    2012-11-01

    Full Text Available Abstract Background Previous work has shown that leaf-cutting ants prefer to cut leaf material with relatively low fungal endophyte content. This preference suggests that fungal endophytes exact a cost on the ants or on the development of their colonies. We hypothesized that endophytes may play a role in their host plants’ defense against leaf-cutting ants. To measure the long-term cost to the ant colony of fungal endophytes in their forage material, we conducted a 20-week laboratory experiment to measure fungal garden development for colonies that foraged on leaves with low or high endophyte content. Results Colony mass and the fungal garden dry mass did not differ significantly between the low and high endophyte feeding treatments. There was, however, a marginally significant trend toward greater mass of fungal garden per ant worker in the low relative to the high endophyte treatment. This trend was driven by differences in the fungal garden mass per worker from the earliest samples, when leaf-cutting ants had been foraging on low or high endophyte leaf material for only 2 weeks. At two weeks of foraging, the mean fungal garden mass per worker was 77% greater for colonies foraging on leaves with low relative to high endophyte loads. Conclusions Our data suggest that the cost of endophyte presence in ant forage material may be greatest to fungal colony development in its earliest stages, when there are few workers available to forage and to clean leaf material. This coincides with a period of high mortality for incipient colonies in the field. We discuss how the endophyte-leaf-cutter ant interaction may parallel constitutive defenses in plants, whereby endophytes reduce the rate of colony development when its risk of mortality is greatest.

    Full Text Available As one of the unique beauties of Bosporus, Bosporus watersides have been composed and formed through long ages along the Bosporus. Not only an architectural form and a residential type, the Bosporus watersides also were being a part of the culture in which they were built. They project the life traditions of the ages in which they were built. Their users were using those buildings as summer resorts, comprised of a hall, wide rooms, kitchen and other components. The gardens of the watersides also have had their own characteristics, and they were setting out unique beauties. The gardens of the watersides in Bosporus were beyond comparison by their organizational schemes and landscape designs. The watersides were designed with a garden within the bounds of spatial possibilities. The gardens were decorated with colorful flowery plants. Many watersides, which were built in Bosporus, have reached until today. As a type of residences, these buildings are among the most important buildings of Bosporus. The Bosporus watersides have unique architectural samples and features and they need to be well preserved. However, it has been identified that some of those structures have disappeared in time. There are many causes for such a removal. By analyzing these causes, we need to preserve these buildings better nowadays. Bosporus watersides and their gardens today need a better protection by effective policies to be produced. Having unique architectural features and styles, those buildings also are a part of our culture. We must better protect our historical and cultural patterns. This is a must to respect our history and culture too.

Artis has meant very much for the inhabitants of the city of Amsterdam during the war. In the first place for the employees and their families, that were kept for starvation and forced labour by extra rations of food and safe hiding places. But also for jewish persons in hiding, who could escape from a certain death by hiding in animal houses or other buildings in the garden. And also for hundreds of thousands people of Amsterdam who found in their zoological garden an oasis of relaxation in a town full of threat and violence.

    2010-01-01

    The U.S. Geological Survey, in cooperation with a consortium of 19 cities, towns, and villages in Dane County, Wis., undertook a study to compare the capability of rain gardens with different vegetative species and soil types to infiltrate stormwater runoff from the roof of an adjacent structure. Two rain gardens, one planted with turf grass and the other with native prairie species, were constructed side-by-side in 2003 at two locations with different dominant soil types, either sand or clay. Each rain garden was sized to a ratio of approximately 5:1 contributing area to receiving area and to a depth of 0.5 foot. Each rain garden, regardless of vegetation or soil type, was capable of storing and infiltrating most of the runoff over the 5-year study period. Both rain gardens in sand, as well as the prairie rain garden in clay, retained and infiltrated 100 percent of all precipitation and snowmelt events during water years 2004-07. The turf rain garden in clay occasionally had runoff exceed its confining boundaries, but was still able to retain 96 percent of all precipitation and snowmelt events during the same time period. Precipitation intensity and number of antecedent dry days were important variables that influenced when the storage capacity of underlying soils would become saturated, which resulted in pooled water in the rain gardens. Because the rooftop area that drained runoff to each rain garden was approximately five times larger than the area of the rain garden itself, evapotranspiration was a small percentage of the annual water budget. For example, during water year 2005, the maximum evapotranspiration of total influent volume ranged from 21 percent for the turf rain garden in clay to 25 percent for the turf rain garden in sand, and the minimum ranged from 12 percent for the prairie rain garden in clay to 19 percent for the prairie rain garden in sand. Little to no runoff left each rain garden as effluent and a small percentage of runoff returned to the

    Home garden is one type of agroecosystem that supports ecosystem services even in the urban settlement. The studies involved literature references and field survey along with a framework of the productive urban landscape that support ecosystem services in home garden. Productive urban landscape provided environmentally, socially and economically benefits that contained in ecosystem services. Problems on limited space in the urban settlement have to be managed by modified home garden system in order to work for ecosystem service in developing productive landscape. This study aimed to assess home garden (Pekarangan) system in a cluster of high density settlement in Yogyakarta City. Structured interview and vegetation identification of home garden have been conducted on 80 samples in Rejowinangun Kotagede District, Yogyakarta City. People showed enthusiasm in ecosystem services provided by home garden “Pekarangan Produktif” through developing productive urban landscape. Some benefits on ecosystem services of home garden were revealed on this study consisted of food production for sale (4.7%), home industry (7.69%), aesthetics (22.65%), food (14.10%), biodiversity (10.68%), ecosystem (12.82%), education (2.56), social interaction (11.54%), recreation (4.70%), and others (8.55%). Nevertheless, vegetation and other elements of home gardens have been managed irregularly and in particularly, the planned home gardens were only 17.07%. Actually, home gardens provided a large set of ecosystem services including being cultural services those are the category most valued. The urban people almost hided the understanding of the cultural benefit of ecosystem services of home garden, even though Yogyakarta has known the cultural city. Thus, urban home garden, as way as “Pekarangan Produktif” in the limited space that managed and planned sustainably, provide many benefits of ecosystem services in a productive urban landscape.

    For the past century, ferroalloy industries in Brescia province, Italy produced particulate emissions enriched in manganese (Mn), lead (Pb), zinc (Zn), copper (Cu), cadmium (Cd), chromium (Cr), iron (Fe), and aluminum (Al). This study assessed metal concentrations in soil and vegetables of regions with varying ferroalloy industrial activity levels. Home gardens (n=63) were selected in three regions of varying ferroalloy plant activity durations in Brescia province. Total soil metal concentration and extractability were measured by X-Ray Fluorescence (XRF), aqua regia extraction, and modified Community Bureau of Reference (BCR) sequential extraction. Unwashed and washed spinach and turnips cultivated in the same gardens were analyzed for metal concentrations by flame atomic absorption spectrometry. Median soil Al, Cd, Fe, Mn, Pb, and Zn concentrations were significantly higher in home gardens near ferroalloy plants compared to reference home gardens. The BCR method yielded the most mobile soil fraction (the sum of extractable metals in Fractions 1 and 2) and all metal concentrations were higher in ferroalloy plant areas. Unwashed spinach showed higher metal concentrations compared to washed spinach. However, some metals in washed spinach were higher in the reference area likely due to history of agricultural product use. Over 60% of spinach samples exceeded the 2- to 4-fold Commission of European Communities and Codex Alimentarius Commission maximum Pb concentrations, and 10% of the same spinach samples exceeded 2- to 3-fold maximum Cd concentrations set by both organizations. Turnip metal concentrations were below maximum standard reference values. Prolonged industrial emissions increase median metal concentrations and most soluble fractions (BCR F1+F2) in home garden soils near ferroalloy plants. Areas near ferroalloy plant sites had spinach Cd and Pb metal concentrations several-fold above maximum standard references. We recommend thorough washing of vegetables

A survey solicited demographic characteristics, FV gardening information, and health-related factors [BMI, self-rated health status, FV intake, physical activity (PA), and perceived neighborhood social cohesion (PNSC)]. The participants were divided into three groups: community gardeners, other types of gardeners, and non-gardeners. Items related to community gardening and perceived changes in health-related factors were presented only to community gardeners. The relationship between community gardening and perceived changes in health-related factors were analyzed by computing correlation coefficients. The relationships between FV gardening and specific health-related factors were analyzed by logistic regression modeling.Results Significant positive correlations were observed between community FV gardening (the frequency of community gardening, the product of community gardening time and frequency of community gardening) and perceived changes in health-related factors (frequency of FV intake, amount of FV intake, and PA). The logistic regression models showed that 1) the number of participants with ≥23 METs h/week of PA was significantly greater among community gardeners than among non-gardeners; 2) the number of participants whose frequency of total vegetable intake, total vegetable intake (excluding juice), and total FV intake (excluding juice) was ≥5 times/day was significantly greater among other types of gardeners than non-gardeners; 3) participants

    Although seed dispersal is a key process determining the regeneration and spread of invasive plant populations, few studies have explicitly addressed the link between dispersal vector behavior and seedling recruitment to gain insight into the invasion process within an urban garden context. We evaluated the role of bird vectors in the dispersal of pokeweed (Phytolacca americana), a North American herb that is invasive in urban gardens in China. Fruiting P. americana attracted both generalist and specialist bird species that fed on and dispersed its seeds. The generalist species Pycnonotus sinensis and Urocissa erythrorhyncha were the most frequent dispersers. Seedling numbers of P. americana were strongly associated with the perching behavior of frugivorous birds. If newly recruited bird species use seedling-safe perching sites, the P. americana will regenerate faster, which would enhance its invasive potential. Based on our observations, we conclude that the 2 main bird vectors, P. sinensis and U. erythrorhyncha, provide potential effective dispersal agents for P. americana. Our results highlight the role of native birds in seed dispersal of invasive plants in urban gardens. © 2016 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

    Full Text Available Historical pomegranate tree in the garden of Atatürk’s House in Thessaloniki storied that planted by the father of Ataturk, Ali Rıza Efendi, has been one of the most attractive points at the museum. However, in addition to the problems of natural ageing period, constructional works in the garden during restoration of the museum and unappropriate prunings caused serious health problems on the tree. For this reason, in order to cease or delay tree collapsing period and prolong survival of the tree, regular maintenance treatments have to be conducted. In this study, technical information has been given regarding the precautions of specific tree maintenance and conservation works, which are normally applied to long lived monumental trees in the literature, on the pomegranate tree. However, these precautions have not been previously applied on such a tree, particularly on the pomegranate tree.

  16. Jan Baptist Xavery (1697-1742: A versatile garden artist

    Full Text Available Dutch garden sculpture from the 18 th century is worthy of more systematic study. Such research may offer valuable insights into the position of garden sculpture within sculpture proper and its meaning in 18 th-century garden art. Jan Baptist Xavery is regarded as one of the most important sculptors working in the Netherlands during the 18 th century. His artistic career, his versatile body of work and his influence on other artists should therefore be studied in more depth. In view of the bloom in garden art in those days Xavery's significance as a 'garden artist' should not be overlooked in such a study. Garden sculptures should not be regarded as independent objects or pure decorative elements, but must be considered within the wider context of garden history. Tragically, many garden ornaments have been removed from their natural green environment. In their new settings they sometimes acquire a new meaning, but more often than not they are not done justice as the original harmonious 'composition' has been lost. As a result, this cultural-historical heritage is often treated indifferently. The few garden sculptures that have survived all calamities and can still be admired in public places are often placed at unsuitable locations and suffer from the weather or vandalism. Many garden sculptures, often damaged, have ended up anonymously in museum depots. Although they are safe there, the dreary catacombs of museums are a far cry from the green surroundings for which they were originally intended. Garden ornaments were, after all, not made for depots but to be looked at, studied and admired by enthusiasts, preferably in green surroundings. Otherwise, they will literally disappear from collective memory. Surely, the talented Jan Baptist Xavery and his contemporaries deserve a better fate than that.

    Identification of active components in a variety of chemical products used directly by consumers is described at both trace and bulk levels using mass spectrometry. The combination of external ambient ionization with a portable mass spectrometer capable of tandem mass spectrometry provides high chemical specificity and sensitivity as well as allowing on-site monitoring. These experiments were done using a custom-built portable ion trap mass spectrometer in combination with the ambient ionization methods of paper spray, leaf spray, and low temperature plasma ionization. Bactericides, garden chemicals, air fresheners, and other products were examined. Herbicide applied to suburban lawns was detected in situ on single leaves 5 d after application.

    Complex structures in nature are often formed by self-assembly. In order to mimic the formation, to enhance the production, or to modify the structures, easy-to-use methods are sought to couple engineering and self-assembly. Chemical-garden-like precipitation reactions are frequently used to study such couplings because of the intrinsic chemical and hydrodynamic interplays. In this work, we present a simple method of applying periodic pressure fluctuations given by a peristaltic pump which can be used to achieve regularly banded precipitate membranes in the copper-phosphate system.

  3. Front gardens to car parks: changes in garden permeability and effects on flood regulation.

    2014-07-01

    This study addresses the consequences of widespread conversion of permeable front gardens to hard standing car parking surfaces, and the potential consequences in high-risk urban flooding hotspots, in the city of Southampton. The last two decades has seen a trend for domestic front gardens in urban areas to be converted for parking, driven by the lack of space and increased car ownership. Despite media and political attention, the effects of this change are unknown, but increased and more intense rainfall, potentially linked to climate change, could generate negative consequences as runoff from impermeable surfaces increases. Information is limited on garden permeability change, despite the consequences for ecosystem services, especially flood regulation. We focused on eight flooding hotspots identified by the local council as part of a wider urban flooding policy response. Aerial photographs from 1991, 2004 and 2011 were used to estimate changes in surface cover and to analyse permeability change within a digital surface model in a GIS environment. The 1, 30 and 100 year required attenuation storage volumes were estimated, which are the temporary storage required to reduce the peak flow rate given surface permeability. Within our study areas, impermeable cover in domestic front gardens increased by 22.47% over the 20-year study period (1991-2011) and required attenuation storage volumes increased by 26.23% on average. These increases suggest that a consequence of the conversion of gardens to parking areas will be a potential increase in flooding frequency and severity - a situation which is likely to occur in urban locations worldwide.

    Identifying the spatial patterns of pollinator visitation rates is key to identifying the drivers of differences in pollination service and the areas where pollinator conservation will provide the highest return on investment. However, gathering pollinator abundance data at the appropriate regional and national scales is untenable. As a surrogate, habitat models have been developed to identify areas of pollinator losses but these models have been developed using expert opinion based on foraging and nesting requirements. Thousands of citizen scientists across the United States participating in The Great Sunflower Project (www.GreatSunflower.org) contribute timed counts of pollinator visits to a focal sunflower variety planted in local gardens and green spaces. While these data provide a more direct measure of pollination service to a standardized plant and include a measure of effort, the data are complicated. Each location is sampled at different dates, times and frequencies as well as different points across the local flight season. To overcome this complication, we have used a generalized additive model to generate regional flight curves to calibrate each individual data point and to attain better estimates of pollination service at each site. Using these flight season corrected data, we identify hotspots and cold spots in pollinator service across the United States, evaluate the drivers shaping the spatial patterns and observe how these data align with the results obtained from predictive models that are based on expert knowledge on foraging and nesting habitats.

    2009-12-01

    Wheat, Triticum aestivum L., producers are often reluctant to use solid-stemmed wheat cultivars resistant to wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), due to concerns regarding yield, efficacy or market opportunities. We evaluated the impact of several planting strategies on wheat yield and quality and wheat stem sawfly infestation at two locations over a three-year period. Experimental units consisted of large plots (50 by 200 m) located on commercial farms adjacent to wheat stem sawfly-infested fields. Compared with a monoculture of a hollow-stemmed cultivar ('AC Barrie'), planting a monoculture of a solid-stemmed cultivar ('AC Eatonia') increased yield by an average of 16% (0.4 mg ha(-1)) and increased the grade of wheat by one unit at the two most heavily infested site-years. Planting a 1:1 blend of AC Eatonia and AC Barrie increased yield by an average of 11%, whereas planting 20- or 40-m plot margins to AC Eatonia increased yield by an average of 8%. High wheat stem sawfly pressure limited the effectiveness of using resistant cultivars in field margins because plants were often infested beyond the plot margin, with uniform infestation down the length of the plots at the two most heavily infested site-years. The effectiveness of AC Eatonia to reduce wheat stem sawfly survivorship was modest in this study, probably due to weather-related factors influencing pith expression and to the high abundance of wheat stem sawfly. Greater benefits from planting field margins to resistant cultivars or planting a blend of resistant and susceptible cultivars might be achievable under lower wheat stem sawfly pressure.

    Full Text Available The forthcoming centenary of the Great War (1914-1918 can be considered an important occasion to focus attention on the subject of memorials for the fallen in the War. Immediately after the War, this topic was considered so relevant that in each municipality of Italy, Gardens and Avenues of Remembrance were realized and soon became places of memory, characterized by strong values of identity, history and landscape. In these places, usually correspondent to the number of fallen in that neighbourhood and located in urban or peripheral areas, nature and anthropic elements coexisted. For their importance, from 1926 these places have been included among the National Monuments. After the Second World War, avenues and gardens, as well as toponyms, were gradually forgotten and, in many cases, radically transformed. Due to a form of damnatio memoriae, which locations considered symbols of past governments have had to pay, these places have been changed, radically transforming also their authentic significance. A century on, it is important to start a programme for protection and enhancement of this historic heritage (classification at a regional and national scale, measurements, archival research, definition of guide lines for conservation. The essay also describes the early results of the classification of Gardens and Avenues of Remembrance in Abruzzo.

The plants introduction in the Botanic Garden PSU have a planned character in a northwest middle taiga. Decorative arboretum was laid in 2000 (Potapova, Prokhorov, 2010. By 2014, the conifers collection includes 159 specimens of 98 cultivars belonging to 28 species, 10 genera and 3 families (Cupressaceae, Pinaceae, Taxaceae. Taxa are presented as species with narrow native habitat (Microbiota decussata, Thujopsis dolabrata, Chamaecyparis pisifera, Picea omorika, and with a wide (Juniperus communis. Plants were planted gradually. Annual plant monitoring include measuring of height, width of the crown, trunk diameter, needles color, seed-bearing, damage. Based on the study was identified plants groups in growth rate, seed-bearing. The number of generative samples are increased from 17 to 53% during 2007-2014. Seed-bearing is not a constant parameter and depends on a complex of abiotic factors.

    The decades-long disposal of manufacturing waste containing perfluoroalkyl substances (PFAS) in landfills resulted in contamination of groundwater serving as the drinking water supply for the eastern Twin Cities metropolitan region. While measures were taken to reduce the levels of PFAS in the drinking water, questions remained about possible non-drinking water pathways of exposure in these communities. The Minnesota Department of Health (MDH) investigated whether PFAS in water used for yard and garden irrigation results in elevated concentrations of PFAS in soil and home-grown produce. In 2010, samples of outdoor tap water, garden soil, and garden produce were collected at homes impacted by the contamination and analyzed for several PFAS. Perfluorobutanoic acid (PFBA) was the primary PFAS present in water, followed by perfluoropentanoic acid (PFPeA). Although PFBA, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) were present in 100% of soil samples at higher concentrations compared to other PFAS, only PFBA was readily translocated to plants. Significant determinants of PFBA concentration in produce were the amount of PFBA applied to the garden via watering and the type of produce tested. Results from this real-world study are consistent with experimental findings that short-chain PFAS have the highest potential to translocate to and bioaccumulate in edible plants. These findings are globally relevant, as short-chain PFAS serve as commercial substitutes for longer-chain compounds and are increasingly detected in water due to their relatively high solubility and mobility.

    A history of the solar garden with the addition of the transparent water ceiling is presented, and a statement of the overall goals of the program is given. The objectives of the water ceiling grant are detailed. The rationale of the transparent water ceiling is developed and its implementation in the solar garden is described. The experimental procedures for evaluating the water ceiling as an integral part of an ongoing garden agricultural experiment are discussed and the results presented. The water ceiling has proven useful in providing extra thermal capacity to the solar garden. It provides heat at night after the water has been warmed during the day and retards overheating in the daytime by absorbing infrared energy into the water. In growing non-flowering plants, such as lettuce and Chinese cabbage, the water ceiling showed no noticeable degradation in yield or maturation rate. In flowering plants, such as tomatoes, the reduced light levels delayed yields by a couple of weeks but the total yield was only slightly diminished. In geographic areas where there is less cloud cover than in Michigan the water ceiling could be much more effective.

    Community gardens are credited for promoting health within neighborhoods, by increasing healthy food intake and exercise frequency. These benefits, however, are potentially undermined as urban soils are often contaminated from industrial legacies. The purpose of this study was to examine the perceived benefits of participation and risks of soil contamination within urban community gardens, and factors associated with soil contamination concerns. Ninety-three gardeners were interviewed across 20 community gardens in St. Louis, Missouri between June and August 2015. Surveys included questions on demographics, gardening practices, and perceptions of community gardening. Multilevel logistic models assessed how gardener demographics, gardening practices, and garden characteristics were associated with soil contamination concerns. Common perceived benefits of community gardening were community building (68.8%), healthy and fresh food (35.5%), and gardening education (18.3%). Most gardeners (62.4%) were not concerned about soil contamination, but nearly half (48.4%) stated concerns about heavy metals. Black race was significantly associated with soil contamination concerns (OR 5.47, 95% CI 1.00-30.15, p = .04). Community gardens offer numerous social and health benefits. Although most gardeners were not concerned about soil contamination, black gardeners were more likely to have concerns. Garden leaders should provide resources to gardeners to learn about soil contamination and methods to manage their risk, particularly in minority neighborhoods.

    Šiauliai University Botanical Garden is a member of the International Phenological Garden network since 2005. It is the only one botanical garden in the East Europe that participated in the programme. In 2015, 18 species were observed. For research, data of 14 plants was used. The aim of this study is to estimate the responsiveness of the species of plants of the phenological garden to annual and monthly precipitation and temperature of the air. The main variables in this investigation were growing season length and the beginning of the growing season. In the period 2006-2015, the lowest annual air temperature was in 2010 (6.0 °C), and the highest was in 2015 (8.9 °C). The lowest precipitation was in 2015 (37.3 mm), and the highest was in 2012 (63.5 mm). The leanest regression among growing length, average annual precipitation, and air temperature showed that statistically significant correlation between growing length and average annual air temperature was found for nine plants, between growing length and precipitation was found for three plants, and between growing length and both factors was found for one plant, Salix smithiana, only. Due to the short evaluating period (2007-2015), consistent regression of the length of the growing season could not be found. The growing length of Betula pubescens sequentially increased. The average growing season of 14 plants starts on April 27 (±3), but for Corylus avellana, it is on April 26 (±3). Longevity of the growing season was the most related with precipitation for C. avellana in summer, autumn, and winter and with air temperature, Ribes alpinum and Salix acutifolia in summer and in autumn.

    Background: For the past century, ferroalloy industries in Brescia province, Italy produced particulate emissions enriched in manganese (Mn), lead (Pb), zinc (Zn), copper (Cu), cadmium (Cd), chromium (Cr), iron (Fe), and aluminum (Al). This study assessed metal concentrations in soil and vegetables of regions with varying ferroalloy industrial activity levels. Methods: Home gardens (n = 63) were selected in three regions of varying ferroalloy plant activity durations in Brescia province. Total soil metal concentration and extractability were measured by X-Ray Fluorescence (XRF), aqua regia extraction, and modified Community Bureau of Reference (BCR) sequential extraction. Unwashed and washed spinach and turnips cultivated in the same gardens were analyzed for metal concentrations by flame atomic absorption spectrometry. Results: Median soil Al, Cd, Fe, Mn, Pb, and Zn concentrations were significantly higher in home gardens near ferroalloy plants compared to reference home gardens. The BCR method yielded the most mobile soil fraction (the sum of extractable metals in Fractions 1 and 2) and all metal concentrations were higher in ferroalloy plant areas. Unwashed spinach showed higher metal concentrations compared to washed spinach. However, some metals in washed spinach were higher in the reference area likely due to history of agricultural product use. Over 60% of spinach samples exceeded the 2- to 4-fold Commission of European Communities and Codex Alimentarius Commission maximum Pb concentrations, and 10% of the same spinach samples exceeded 2- to 3-fold maximum Cd concentrations set by both organizations. Turnip metal concentrations were below maximum standard reference values. Conclusions: Prolonged industrial emissions increase median metal concentrations and most soluble fractions (BCR F1 + F2) in home garden soils near ferroalloy plants. Areas near ferroalloy plant sites had spinach Cd and Pb metal concentrations several-fold above maximum standard references

    Over the next few decades NASA and private enterprise missions plan to send manned missions to Mars with the ultimate aim to establish a permanent human presence on this planet. For a self-sustaining colony on Mars it will be necessary to provide food by growing plants in sheltered greenhouses on the Martian surface. As part of an undergraduate student project in Astrobiology at Villanova University, experiments are being carried out, testing how various plants grow in Martian regolith. A wide sample of plants are being grown and tested in Mars regolith simulant commercially available from The Martian Garden (TheMartian Garden.com). This Mars regolith simulant is based on Mojave Mars Simulant (MMS) developed by NASA and JPL for the Mars Phoenix mission. The MMS is based on the Mojave Saddleback basalt similar that used by JPL/NASA. Additional reagents were added to this iron rich basalt to bring the chemical content close to actual Mars regolith. The MMS used is an approximately 90% similar to regolith found on the surface of Mars - excluding poisonous perchlorates commonly found on actual Mars surface.The students have selected various vegetables and herbs to grow and test. These include carrots, spinach, dandelions, kale, soy beans, peas, onions, garlic and of course potatoes and sweet potatoes. Plants were tested in various growing conditions, using different fertilizers, and varying light conditions and compared with identical “control plants” grown in Earth soil / humus. The results of the project will be discussed from an education view point as well as from usefulness for fundamental research.We thank The Martian Garden for providing Martian regolith simulant at education discounted prices.

    Further data on soil to plant transfer factors is provided for Cs-137 and Pu-239+240, as an extension of results presented at the previous IUR Workshop at Wageningen in December 1982. Field crops of grass, barley and oats produced in 1982 at 11 locations in Britain were analysed for radionuclides. Analysis of soils that produced these crops showed that they contained 'background' nuclear weapons fallout concentrations of Cs-137 and plutonium which were elevated in regions with high rainfall. Analysis of basic soil properties was also made. In separate experiments, transfer factors were derived for 10 crop plants grown in pot trials under glasshouse conditions. In one trial the soil used contained low concentrations of radionuclides derived from nuclear weapons fallout. In a second trial a brown earth was used, which contained additional radionuclides from long-term deposition by nuclear fuel reprocessing. (orig.)

  2. Responses of Plant Community Composition to Long-term Changes in Snow Depth at the Great Basin Desert - Sierra Nevada ecotone.

    Snowfall is the dominant hydrologic input for many high-elevation ecosystems of the western United States. Many climate models envision changes in California's Sierra Nevada snow pack characteristics, which would severely impact the storage and release of water for one of the world's largest economies. Given the importance of snowfall for future carbon cycling in high elevation ecosystems, how will these changes affect seedling recruitment, plant mortality, and community composition? To address this question, experiments utilize snow fences to manipulate snow depth and melt timing at a desert-montane ecotone in eastern California, USA. Long-term April 1 snow pack depth averages 1344 mm (1928-2015) but is highly variable from year to year. Snow fences increased equilibrium drift snow depth by 100%. Long-term changes in snow depth and melt timing are associated with s shift from shurbs to graminoids where snow depth was increased for >50 years. Changes in snow have impacted growth for only three plant species. Moreover, annual growth ring increments of the conifers Pinus jeffreyi and Pi. contorta were not equally sensitive to snow depth. There were over 8000 seedlings of the shrubs Artemisia tridentata and Purshia tridentata found in 6300 m2 in summer 2009, following about 1400 mm of winter snow and spring rain. The frequency of seedlings of A. tridentata and P. tridentata were much lower on increased-depth plots compared to ambient-depth, and reduced-depth plots. Survival of the first year was lowest for A. tridentata. Survival of seedlings from the 2008 cohort was much higher for P. tridentata than A. tridentata during the 2011-2015 drought. Results indicate complex interactions between snow depth and plant community characteristics, and that responses of plants at this ecotone may not respond similarly to increases vs. decreases in snow depth. These changes portend altered carbon uptake in this region under future snowfall scenarios.

    Vaccination against human papillomavirus (HPV) is routinely recommended for ages 11-12, yet in 2016 only 49.5% of women and 37.5% of men had completed the three-dose series in the United States. Offering information and cues to action through a serious videogame for preteens may foster HPV vaccination awareness, information seeking, and communication. An iterative process was used to develop an interactive videogame, Land of Secret Gardens. Three focus groups were conducted with 16 boys and girls, ages 11-12, for input on game design, acceptability, and functioning. Two parallel focus groups explored parents' (n = 9) perspectives on the game concept. Three researchers identified key themes. Preteens wanted a game that is both entertaining and instructional. Some parents were skeptical that games could be motivational. A back-story about a secret garden was developed as a metaphor for a preteen's body and keeping it healthy. The goal is to plant a lush secret garden and protect the seedlings by treating them with a potion when they sprout to keep them healthy as they mature. Points to buy seeds and create the potion are earned by playing mini-games. Throughout play, players are exposed to messaging about HPV and the benefits of the vaccine. Both boys and girls liked the garden concept and getting facts about HPV. Parents were encouraged to discuss the game with their preteens. Within a larger communication strategy, serious games could be useful for engaging preteens in health decision making about HPV vaccination.

    Understanding the seasonal dynamics of soil fertility is a key to providing decision support for rational use of fertilizers in tea gardens. In this study, seasonal variation in fertility parameters and the comprehensive fertility of 3 types of tea garden soils in western Sichuan, China, were investigated using a field survey and laboratory analysis. The results showed that pH, available phosphorus (AP), and available potassium (AK) in yellow earth remained low regardless of season; the lowest levels (among all soils) of total organic carbon (TOC) and total nitrogen (TN) occurred in yellow earth during spring and summer. Higher TOC, TN, and AP content occurred in spring due to basal fertilizer application; TOC was lower in summer due to higher decomposition rates and extensive soil erosion; lower TN and AP contents in summer were attributed to absorption by tea plants and to soil erosion; higher TOC and TN in autumn occurred as litter returned to the soil. Seasonal variation in AK was less obvious than that of the other fertility parameters. The comprehensive fertility of tea garden soils, ranked in order from higher to lower by season and soil type, was as follows: spring > autumn > summer for bleached paddy soil and yellow earth; but spring > summer > autumn for acid purple soil. Among the 3 tea garden soils, the fertility of acid purple soil was highest, and that of yellow earth was lowest in every season. Fertility was highest in spring for all soils. These results can provide a theoretical basis for scientific management of tea plantations in western Sichuan and similar regions. (author)

    To mitigate the negative effects of modern cities on health, scientists are focusing on the diverse benefits of natural environments; a conceptual approach to use gardens for promoting human health is being attempted. In this study, the effects of the visual landscape of a traditional garden on psychological and physiological activities were investigated. Eighteen male and female adults participated in this indoor experiment (mean age, 26.7 years). Twelve different landscape images for city and garden were presented continuously for 90 s. In the time series changes of oxygenated hemoglobin (O₂Hb), different patterns of changes were observed between the city and garden. The mean O₂Hb values increased for the city landscapes, whereas they decreased for the garden landscapes both in the left and right prefrontal cortices. Significant differences in the negative psychological states of tension, fatigue, confusion, and anxiety were observed between the city and garden landscapes. Important differences in the physiological and psychological responses to the two different landscapes were also detected between male and female participants, providing valuable clues to individual differences in the health benefits of natural landscapes. To validate the use of gardens as a resource for promoting health in urban dwellers, further scientific evidence, active communication, and collaboration among experts in the relevant field are necessary.

  7. Garden of Ambivalence The Topology of the Mother-child Dyad in Grey Gardens

    Full Text Available The Maysles brothers’ 1975 documentary, Grey Gardens, portrays the lives of Edith Bouvier Beale and her daughter, Edith, known as Little Edie, the aunt and first cousin, respectively, of Jacqueline Bouvier Kennedy Onassis. The mother and daughter live together in their East Hampton house that is literally falling apart. As their identical names imply, the Beales share a symbiotic relationship which is reflected in every aspect of their life. I argue that Grey Gardens calls for Julia Kristeva’s insistence on abjection as a crucial struggle with “spatial ambivalence (inside/outside uncertainty” and an attempt to mark out a space in the undifferentiated field of the mother-child symbiosis. In Powers of Horror, Kristeva (1982 states, “abjection preserves what existed in the archaism of pre-objectal relationship” (p. 10. Grey Gardens portrays the topology of the mother-child dyad, which pertains to a particular spatio-temporality: where this primordial relationship is concerned, object and subject crumble, and the distinction between past and present is irrelevant.

    2007-10-01

    Phytoceuticals (non-nutritional but beneficial plant chemicals) merit investigation as pharmacotherapy for asthma and chronic obstructive pulmonary disease (COPD). Although asthma is mostly treated adequately, COPD is not. Thus, there is a need for new drugs with improved therapeutic benefit, especially in COPD. Recent interest in herbal remedies has redirected attention towards plants as sources of improved treatments for lung disease. Phytoceuticals from a variety of plants and plant products, including butterbur, English ivy, apples, chocolate, green tea and red wine, demonstrate broad-spectrum pharmacotherapeutic activities that could be exploited in the clinic. Well-designed clinical trials are required to determine whether these beneficial activities are reproduced in patients, with the prospect that phytoceuticals are the new physic garden for asthma and COPD.

    Plant-soil variation related to perennial-plant resource islands (coppices) interspersed with relatively bare interspaces is a major source of heterogeneity in desert rangelands. Our objective was to determine how native and exotic grasses vary on coppice mounds and interspaces (microsites) in unburned and burned sites and underlying factors that contribute to the variation in sagebrush-steppe rangelands of the Idaho National Lab, where interspaces typically have abiotic crusts. We asked how the exotic cheatgrass (Bromus tectorum L.) and native bluebunch wheatgrass (Pseudoroegneria spicata [Pursh] A. Löve) were distributed among the microsites and measured their abundances in three replicate wildfires and nearby unburned areas. We conducted a common-garden study in which soil cores from each burned microsite type were planted with seed of either species to determine microsite effects on establishment and growth of native and exotic grasses. We assessed soil physical properties in the common-garden study to determine the intrinsic properties of each microsite surface and the retention of microsite soil differences following transfer of soils to the garden, to plant growth, and to wetting/drying cycles. In the field study, only bluebunch wheatgrass density was greater on coppice mounds than interspaces, in both unburned and burned areas. In the common-garden experiment, there were microsite differences in soil physical properties, particularly in crust hardness and its relationship to moisture, but soil properties were unaffected by plant growth. Also in the experiment, both species had equal densities yet greater dry mass production on coppice-mound soils compared to interspace soils, suggesting microsite differences in growth but not establishment (likely related to crust weakening resulting from watering). Coppice-interspace patterning and specifically native-herb recovery on coppices is likely important for postfire resistance of this rangeland to cheatgrass.

    Walter R Tschinkel

    Full Text Available Soil invertebrates such as ants are thought to be important manipulators of soils in temperate and tropical ecosystems. The fungus gardening ant, Trachymyrmex septentrionalis, is an important agent of biomantling, that is, of depositing soil excavated from below onto the surface, and has been suggested as an agent of bioturbation (moving soil below ground as well. The amount of bioturbation by this ant was quantified by planting queenright colonies in sand columns consisting of 5 layers of different colored sand. The amount of each color of sand deposited on the surface was determined from April to November 2015. In November, colonies were excavated and the color and amount of sand deposited below ground (mostly as backfill in chambers was determined. Extrapolated to one ha, T. septentrionalis deposited 800 kg of sand per annum on the surface, and an additional 200 kg (17% of the total excavated below ground. On average, this mixes 1.3% of the sand from other layers within the top meter of soil per millennium, but this mixing is unlikely to be homogeneous, and probably occurs as "hotspots" in both horizontal and vertical space. Such mixing is discussed as a challenge to sediment dating by optically stimulated luminescence (OSL.

    Food waste is one of the main problems in our society. This is mainly caused by people's behaviors and attitudes, which influence the whole food chain, from production to final consumption. In fact, food is generally perceived as a commodity by adults, who transmit this behavior to children, who in turn do not develop any consciousness about food's source. One way to reduce the problem seems to be by changing consumers' attitudes, which develop during the early years of childhood. Research has shown that after attending school garden classes, children's food-related behavior changes. Growing crops is not always easy--it can't be done in the domestic space, and this lead to a loss of the long term positive effects. This paper presents a project that tries to teach children how to grow their own food indoors and outdoors, mixing real and virtual reality, connecting something natural like a plant to the Internet of Things (or IOT, a network of physical objects virtually connected to each other and to the web). The use of sensors related to an app makes this process more fun and useful for educational purposes. The aim of the project is to change children's attitude towards food, increasing their knowledge about production and consumption, in order to reduce waste on a long term basis. The research has been developed in collaboration with Cisco NL and MediaLAB Amsterdam. The user testing has been executed with Dutch children in Amsterdam.

    Previous studies investigating the effect of flower patch size on insect flower visitation rate have compared relatively large patches (10-1000s m2) and have generally found a negative relationship per unit area or per flower. Here, we investigate the effects of patch size on insect visitation in patches of smaller area (range c. 0.1-3.1 m2), which are of particular relevance to ornamental flower beds in parks and gardens. We studied two common garden plant species in full bloom with 6 patch sizes each: borage (Borago officinalis) and lavender (Lavandula × intermedia 'Grosso'). We quantified flower visitation by insects by making repeated counts of the insects foraging at each patch. On borage, all insects were honey bees (Apis mellifera, n = 5506 counts). On lavender, insects (n = 737 counts) were bumble bees (Bombus spp., 76.9%), flies (Diptera, 22.4%), and butterflies (Lepidoptera, 0.7%). On both plant species we found positive linear effects of patch size on insect numbers. However, there was no effect of patch size on the number of insects per unit area or per flower and, on lavender, for all insects combined or only bumble bees. The results show that it is possible to make unbiased comparisons of the attractiveness of plant species or varieties to flower-visiting insects using patches of different size within the small scale range studied and make possible projects aimed at comparing ornamental plant varieties using existing garden flower patches of variable area.

    Community gardens are viewed as a potentially useful environmental change strategy to promote active and healthy lifestyles but the scientific evidence base for gardens is limited. As a step towards understanding whether gardens are a viable health promotion strategy for local communities, we set out to examine the social processes that might explain the connection between gardens, garden participation and health. We analyzed data from semi-structured interviews with community gardeners in Denver. The analysis examined social processes described by community gardeners and how those social processes were cultivated by or supportive of activities in community gardens. After presenting results describing these social processes and the activities supporting them, we discuss the potential for the place-based social processes found in community gardens to support collective efficacy, a powerful mechanism for enhancing the role of gardens in promoting health.

  2. Closing the Gap: Communicating to Change Gardening Practices in Support of Native Biodiversity in Urban Private Gardens

    2012-03-01

    Full Text Available Private gardens collectively comprise the largest green space in most cities and the greatest potential for increasing the extent of wildlife-friendly and native-dominated habitat, improving the quality of ecosystem services, and providing opportunities for urban dwellers to reconnect with nature. Because attitudes and values driving landscape preferences in gardens are complex and often not conducive to biodiversity, and a gap exists between the possession of knowledge or values and the expression of pro-environmental behavior, facilitating change in gardening behavior is challenging. We attempted to improve knowledge and influence values, attitudes, and gardening behavior of 55 householders in favor of native biodiversity and environmentally friendly practices, through a two-way communication process, or interactive dialog, during a process of biodiversity documentation of their gardens. Informative feedback on their garden with a normative component was also provided. Despite being well educated and knowledgeable about common species at the start of the study, an increase in knowledge and shift in attitude was detected in 64% of householders: 40% reported a greater understanding of wildlife, and 26% made changes in their gardens, 13% to support native biodiversity. The normative component of our feedback information was of particular interest to 20% of householders. Because neighborhood norms influence gardening practices, changes adopted by a proportion of householders should be perpetuated across neighborhoods. The process of biodiversity assessment, dialog, and feedback was effective in improving knowledge of wildlife and native species, and stimulated a shift in attitude that resulted in native-friendly gardening practices. These changes were detected primarily through open self-report questions, rather than quantitative measures.

    A recent roof renovation at the University of Texas Health Science Center in Houston (UTHSC) was based on the principles of sustainable development in order to create a place of health and well-being and to pursue integrated design solutions. The project addressed issues associated with the urban heat island condition, and problematic air quality in Houston. The first roofing option that was considered was Cool Roofing that would use either a white reflective surfacing or a garden roof. One of the buildings planned for roof replacement was the School of Public Health, a 10-storey structure composed of structural concrete framing. The existing roof system consisted of a spray-applied polyurethane foam roof covering applied over a gravel surfaced built-up roof membrane that was installed over a thermosetting asphaltic fill installed over a structural concrete deck. It was determined that this roof would be a good potential candidate for the installation of an extensive garden roof system. Four different mock-up samples of various extensive garden roof assemblies were constructed to test representative material types and assemblies. The subject area was divided into the following 4 quadrants in which the following systems were installed: (1) American Hydrotech system with Monolithic Membrane 6125-FR consisting of a hot-applied rubberized liquid asphalt reinforced with a polyester fabric, (2) Sarnafil G 476 system consisting of a prefabricated, fiberglass reinforced PVC thermoplastic single-ply membrane that is 80 mils thick, (3) Grace system with Procor Deck System 3R consisting of a cold-vulcanized, fluid-applied synthetic rubber membrane with a polyester reinforcing fabric, and (4) Siplast with Teranap System consisting of a two-ply SBS modified bitumen membrane composed of a smooth-surfaced modified bitumen fiberglass-reinforced base. After the installation of the growing medium, UTHSC personnel planted a variety of vegetation species and seeds in the quadrants

    Urban community gardens provide affordable, locally grown, healthy foods and many other benefits. However, urban garden soils can contain lead (Pb) that may pose risks to human health. To help evaluate these risks, we measured Pb concentrations in soil, vegetables, and chicken eggs from New York City community gardens, and we asked gardeners about vegetable consumption and time spent in the garden. We then estimated Pb intakes deterministically and probabilistically for adult gardeners, children who spend time in the garden, and adult (non-gardener) household members. Most central tendency Pb intakes were below provisional total tolerable intake (PTTI) levels. High contact intakes generally exceeded PTTIs. Probabilistic estimates showed approximately 40 % of children and 10 % of gardeners exceeding PTTIs. Children's exposure came primarily from dust ingestion and exposure to higher Pb soil between beds. Gardeners' Pb intakes were comparable to children's (in µg/day) but were dominated by vegetable consumption. Adult household members ate less garden-grown produce than gardeners and had the lowest Pb intakes. Our results suggest that healthy gardening practices to reduce Pb exposure in urban community gardens should focus on encouraging cultivation of lower Pb vegetables (i.e., fruits) for adult gardeners and on covering higher Pb non-bed soils accessible to young children. However, the common practice of replacement of root-zone bed soil with clean soil (e.g., in raised beds) has many benefits and should also continue to be encouraged.

    Community gardens enhance nutrition and physical activity and promote the role of public health in improving quality of life. Opportunities to organize around other issues and build social capital also emerge through community gardens. California Healthy Cities and Communities (CHCC) promotes an inclusionary and systems approach to improving community health. CHCC has funded community-based nutrition and physical activity programs in several cities. Successful community gardens were developed by many cities incorporating local leadership and resources, volunteers and community partners, and skills-building opportunities for participants. Through community garden initiatives, cities have enacted policies for interim land and complimentary water use, improved access to produce, elevated public consciousness about public health, created culturally appropriate educational and training materials, and strengthened community building skills.

    2017-06-01

    Full Text Available The purpose of the article is to examine the relationship between a so-called "garden leave" clause and a post-termination restraint of trade clause in employment contracts, in view of the decision in Vodacom (Pty Ltd v Motsa 2016 3 SA 116 (LC. The Labour Court grappled with the question of whether the enforcement of the garden leave provision impacts on the enforcement of a post-termination restraint of trade clause. Enforcement of both these types of clauses may be problematic. It can result in unfairness if an employee ends up being commercially inactive for a long period. The author argues that garden leave has a direct effect on the enforcement of a post- termination restraint of trade clause. Accordingly, a restraint of trade will be enforced only if the employer's proprietary interest requires additional protection beyond what is achieved under the garden leave clause.

    The purpose of this study was to examine the frequency of gardening/yard work in relation to depressive symptoms in African-Americans while controlling for biological and social factors. A secondary analysis was performed on the National Survey of American Life (n=2,903) using logistic regression for complex samples. Gardening/Yard work was measured by self-reported frequency. Depressive symptoms were measured with the Center for Epidemiologic Studies Depression scale. Biological and social factors, not gardening/yard work, were associated with depressive symptoms. Biological and social factors may need to be addressed before the association between gardening/yard work and depressive symptoms can be determined. Copyright © 2015 Elsevier Inc.

    Since the Great East Japan Earthquake on 11 March 2011, Iitate Village has continued to be classified as a deliberate evacuation area, in which residents are estimated to receive an annual additional effective radiation dose of >20 mSv. Some companies still operate in Iitate Village, with a special permit from the Cabinet Office Team in Charge of Assisting the Lives of Disaster Victims. In this study, we measured the annual effective radiation dose to workers in Iitate Village from 15 January to 13 December 2013. The workers stayed in Iitate for 10 h and left the village for the remaining 14 h each working day. They worked for 5 days each week in Iitate Village, but stayed outside of the village for the remaining 2 days each week. We found that the effective radiation dose of 70% of the workers was <2 mSv, including natural radiation; the maximum dose was 3.6 mSv. We estimated the potential annual additional effective radiation dose if people returned full-time to Iitate. Our analysis supports the plan for people to return to their home village at the end of 2017

    Full Text Available Mutaqien Z, Zuhri M (2011 Establishing a long-term permanent plot in remnant forest of Cibodas Botanic Garden, West Java. Biodiversitas 12: 218-224. Cibodas Botanic Garden (CBG has unique characters; almost 10% of which is forested area adjacent to the natural forest of Mt. Gede Pangrango National Park. The area is a transition between natural forest and artificial habitat which mostly consists of exotic plant species. The permanent plot in CBG was established in 2007-2009. Two hundred and eighty four units of 10x10 square meters sub-plot were established in four locations, i.e. Wornojiwo, Kompos, Jalan Akar, and Lumut forest. Vegetation analyses were conducted for trees, saplings, shrubs, and herb species. The inventory found 137 species plants consisting of 74 tree species dominated by Villebrunea rubescens (Bl. Bl. and Ostodes paniculata Bl., 30 shrub species dominated by Strobilanthes hamiltoniana (Steud., 24 herb species dominated by Cyrtandra picta Bl., 6 fern species mainly consisted of Diplazium pallidum Moore, and 3 climber species dominated by Calamus reinwardtii Mart. In comparison with the natural forest of Mt. Gede Pangrango National Park, the CBG permanent plot showed a good representative of the vegetation of lower montane forest. A regular monitoring during the successive years is needed to maintain diversity, monitor forest dynamics and anticipate the spread of invasive plant from CBG.
