  7. [Lysenkoism in Polish botany].

    Köhler, Piotr

    2008-01-01

    Lysenkoism by PAN came with the Sixth General Assembly of its members on June 11-12, 1956. The second tier of propagating Lysenkoism consisted in activities aimed at the general public, including the teaching of creative Darwinism (obligatory for pupils of various levels of education), in the school years 1949/50-1956/57. There were few botanists who published studies in Lysenkoism: only 55 persons did so. Among them, there were only a few botanists who could boast of significant previous scientific achievements--they included Stefan Białobok (1909-1992), Władysław Kunicki-Goldfinger (1916-1995), Edmund Malinowski (1885-1979), Konstanty Moldenhawer (1889-1962), Józef Motyka (1900-1984), Szczepan Pieniazek. A majority of the authors of publication in Lysenkoism were young scientists or people who did publish anything later on. Basing on the available bibliographies, it is possible to ascertain that there were ca. 140 Lysenkoist botanical publications (out of the total of 3410), i.e. 4.1% (fig. 1) of all the botanist publications in Poland in that period. Their number in the years 1949-1953 was higher than in the next period, and oscillated between 15 and 24 publications annually (fig. 2). The percentage of Lysenkoist studies among all publications in botany published each year was highest in 1949 (11.5%), and decreased systematically in the following years (fig. 3). Lysenkoism was a marginal phenomenon in Polish botany. Among the Lysenkoist publications, most summarized papers delivered at successive conferences, or consisted in reprints of Soviet studies. A significant group was made up of publications popularizing the principles and achievements of Lysenkoism (on the basis of Soviet publications). There were relatively studies presenting the results of research conducted in Poland on the basis of Lysenko's theory. Botanists who remember those times recollect that topics connected with Michurinian-Lysenkoist biology were avoided. It is symptomatic that not a single

  8. Lysenko affair and Polish botany.

    Köhler, Piotr

    2011-01-01

    This article describes the slight impact of Lysenkoism upon Polish botany. I begin with an account of the development of plant genetics in Poland, as well as the attitude of scientists and the Polish intelligentsia toward Marxist philosophy prior to the World War II. Next I provide a short history of the introduction and demise of Lysenkoism in Polish science, with a focus on events in botany, in context with key events in Polish science from 1939 to 1958. The article outlines the little effects of Lysenkoism upon botanists and their research, as well as how botanists for the most part rejected what was often termed the "new biology." My paper shows that though Lysenko's theories received political support, and were actively promoted by a small circle of scientists and Communist party activists, they were never accepted by most botanists. Once the political climate in Poland altered after the events of 1956, Lysenko's theories were immediately abandoned. PMID:20665091

  9. Botany in Edinburgh's Medical Curriculum.

    Wilson, Hazel

    2012-01-01

    In the early 18th century, at the founding of Edinburgh University Medical School, the study of botany was regarded as an essential component of medical training. Botanical teaching began as basic instruction in the recognition of medical plants, considered a vital aspect of a physician's Materia Medica studies. Over the next hundred years growing importance was given to the study of botany as a science, its popularity peaking under John Hutton Balfour's tenure as Professor (1845-1879). The relevance of botanical study later declined in the undergraduate medical curriculum until its cessation in 1961 .This paper considers the history of botanical studies in Edinburgh, including the reasons for its introduction and its changing importance over time.

    2004-01-01

    Domain-specific ontologies are greatly useful in knowledge acquisition, sharing and analysis. In this paper, botany-specific ontology for acquiring and analyzing botanical knowledge is presented. The ontology is represented in a set of well-defined categories, and each concept is viewed as an instance of certain category. The authors also introduce botany-specific axioms, an integral part of the ontology, for checking and reasoning with the acquired knowledge. Consistency, completeness and redundancy of the axioms are discussed.

Thus we want to explore the shift between two conflicting types of biopolitics: the botanical policy of the Metropolis and the political botany in the colonies. This is a distinction that refers to the shift from an organizational model based on the production of data towards one that assigns and redistributes ...

  16. Forensic Botany: Evidence and Analysis.

    Coyle, H M

    2009-01-01

    Forensic botany is the use of plant evidence in matters of law. While plant fragments are often collected as trace evidence, they are only occasionally identified using microscopy and are still more rarely assessed using molecular biology techniques for individualization and sourcing of a sample. There are many different methods useful for DNA typing of plants; this review focuses on those techniques (DNA sequencing, STR, AFLP, RAPD) most relevant to the forensic science community and on those methods currently in practice. Plant evidence is commonly associated with homicides, with clandestine graves, as trace pollen on clothing, vehicles, or packaging, or in the transport of illicit drugs. DNA can be especially useful for the identification of minute quantity of samples, for differentiation of plants that lack distinguishing morphological features, and for generating a unique identifier for associative forensic evidence.

  4. Elements of plant physiology in theophrastus' botany.

    Pennazio, Sergio

    2014-01-01

    For thousands of years the plants were considered only as a source of food and medicine, and as ornamental objects. Only from the fifth century BC, some philosophers of Ancient Greece realized that the plants were living organisms but, unfortunately, their works have come to us as fragments that we often know from the biological works of Aristotle. This eminent philosopher and man of science, however, did not give us a complete work on the plants, which he often promised to write. From scattered fragments of his conspicuous biological work, it emerges a concept of nutritive soul that, in the presence of heat and moisture, allows plants to grow and reproduce. The task of writing a comprehensive botanical work was delegated to his first pupil, Theophrastus, who left us two treatises over time translated into the various languages up to the current versions (Enquiry into plants, On the causes of plants). The plant life is described and interpreted on the basis of highly accurate observations. The physiological part of his botany is essentially the nutrition: According to Theophrastus, plants get matter and moisture from the soil through root uptake and process the absorbed substances transforming them into food, thanks to the heat. The processing (pepsis, coction) of matter into the food represents an extraordinary physiological intuition because individual organs of a plant appear to perform its specific transformation. Despite that Theophrastus did not do scientific experiments or use special methods other than the sharpness of his observations, he can be considered the forerunner of a plant physiology that would take rebirth only after two millennia.

    Smocovitis, Vassiliki Betty

    2014-03-01

    This paper examines the crucial early history of the American Journal of Botany from the years following the founding of the Botanical Society of America in 1906 to the termination of the agreement for publication with the Brooklyn Botanic Garden in 1935. It examines the efforts of individuals like F. C. Newcombe, who did the most to raise support for the journal and became the first Editor-in-Chief, in the context of the growing numbers of professional botanists and plant scientists who were actively engaged in research requiring appropriate publication venues and in the process of forming an independent identity as "American botanists." It also examines the launching of the journal in the context of the Great War in Europe and the transition from German botany to American botany in the second decade of the 20th century.

    2011-02-01

    Acanthopanax senticosus (Rupr. et Maxim) Harms (Araliaceae), also called Siberian Ginseng, Eleutherococcus senticosus, and Ciwujia in Chinese, is a widely used traditional Chinese herb that could invigorate qi, strengthen the spleen, and nourish kidney in the theory of Traditional Chinese Medicine. With high medicinal value, Acanthopanax senticosus (AS, thereafter) is popularly used as an "adaptogen" like Panax ginseng. In recent decades, a great number of chemical, pharmacological, and clinical studies on AS have been carried out worldwide. Several kinds of chemical compounds have been reported, including triterpenoid saponins, lignans, coumarins, and flavones, among which, phenolic compounds such as syringin and eleutheroside E, were considered to be the most active components. Considerable pharmacological experiments both in vitro and in vivo have persuasively demonstrated that AS possessed anti-stress, antiulcer, anti-irradiation, anticancer, anti-inflammatory and hepatoprotective activities, etc. The present review is an up-to-date and comprehensive analysis of the botany, chemistry, pharmacology, toxicity and clinical trials of AS.

    1980-03-24

    In cooperation with Davy McKee, Linde will provide design, procurement, and construction services for ICI Australia's 250,000 ton/yr ethylene cracker at Botany, N.S.W., which will form the basis of a $400 million (Aust.) plastics and petrochemical facilities expansion project at the site. The new plant will initially use naphtha feedstock from nearby refineries but will also be designed to use other domestic resources, particularly LPG from the Bass Strait or Cooper Basin when a new pipeline from the latter is completed. When completed in the first quarter of 1983, the cracker will supply existing 70,000 ton/yr low-density polyethylene and 25,000 ton/yr ethylene oxide plants, which are now being debottlenecked at the site. These plants are now supplied with 20,000 tons/yr each of ethylene by Showa Yuka K.K. and Tonen Petrochemical. Showa Denko K.K. has started delivery of the first 3600 tons of ethylene under a new 20,000 ton/yr supply deal over the next three years. ICI plans to build a second $500 million (Aust.) ethylene plant at Point Wilson, Victoria, for completion in 1985 to supply caustic soda, chlorine, ethylene dichloride, and vinyl chloride units.

    2006-07-01

    This paper offers highlights from the 100 (plus) years of the Botanical Society of America (BSA) and draws extensively on the archives of the BSA. In addition to examining the founding of the society and the attempt to "professionalize" botany in late 19th century America, the paper also explores the complex relations between the BSA and a number of related societies in the United States, the Society's struggle to create a coherent identity for itself, the place of botany as a whole in the context of the burgeoning biological sciences in the 20th century, and the changing role of the BSA in an international context. The paper assesses both the achievements and the challenges facing the BSA. It closes by offering some historical reflections on the status of "botany" as a science and the historical significance of terms like "plant biology" and "plant science." PMID:21642158

    Although investigations in Botany, governed in a measure by the sparsely settled condition of the regions visited, are but incidental to the systematic purpose of the Survey, which has for its main object the determination of data necessary for the construction of a detailed topographical map, yet it is believed that the material here presented, as the result of examination, by specialists, of large and complete collections, will have its value as a substantial contribution to the knowledge of the Botany of portions of the United States west of the 1OOth meridian and south of the 40th parallel.

  8. The plant microbiome explored: implications for experimental botany.

    Berg, Gabriele; Rybakova, Daria; Grube, Martin; Köberl, Martina

    2016-02-01

    The importance of microbial root inhabitants for plant growth and health was recognized as early as 100 years ago. Recent insights reveal a close symbiotic relationship between plants and their associated microorganisms, and high structural and functional diversity within plant microbiomes. Plants provide microbial communities with specific habitats, which can be broadly categorized as the rhizosphere, phyllosphere, and endosphere. Plant-associated microbes interact with their host in essential functional contexts. They can stimulate germination and growth, help plants fend off disease, promote stress resistance, and influence plant fitness. Therefore, plants have to be considered as metaorganisms within which the associated microbes usually outnumber the cells belonging to the plant host. The structure of the plant microbiome is determined by biotic and abiotic factors but follows ecological rules. Metaorganisms are co-evolved species assemblages. The metabolism and morphology of plants and their microbiota are intensively connected with each other, and the interplay of both maintains the functioning and fitness of the holobiont. Our study of the current literature shows that analysis of plant microbiome data has brought about a paradigm shift in our understanding of the diverse structure and functioning of the plant microbiome with respect to the following: (i) the high interplay of bacteria, archaea, fungi, and protists; (ii) the high specificity even at cultivar level; (iii) the vertical transmission of core microbiomes; (iv) the extraordinary function of endophytes; and (v) several unexpected functions and metabolic interactions. The plant microbiome should be recognized as an additional factor in experimental botany and breeding strategies. PMID:26547794

  9. On New Spain and Mexican medicinal botany in cardiology.

    de Micheli-Serra, Alfredo Alessandro; Izaguirre-Ávila, Raúl

    2014-01-01

    Towards the middle of the XVI century, the empirical physician Martín de la Cruz, in New Spain, compiled a catalogue of the local medicinal herbs and plants, which was translated into Latin by Juan Badiano, professor at the Franciscan college of Tlatelolco. On his side, Dr. Francisco Hernández, the royal physician (protomédico) from 1571 until 1577, performed a systematic study of the flora and fauna in this period. His notes and designs were not published at that time, but two epitomes of Hernández' works appeared, respectively, in 1615 in Mexico and in 1651 in Rome. During the XVIII century, two Spanish scientific expeditions arrived to these lands. They were led, respectively, by the Spanish naturalist Martín Sessé and the Italian seaman, Alessandro Malaspina di Mulazzo, dependent from the Spanish Government. These expeditions collected and carried rich scientific material to Spain. At the end of that century, the Franciscan friar Juan Navarro depicted and described several Mexican medicinal plants in the fifth volume of his botanic work. In the last years of the colonial period, the fundamental works of Humboldt and Bonpland on the geographic distribution of the American plants were published. In the modern age, the first research about the Mexican medicinal botany was performed in the laboratory of the Instituto Médico Nacional [National Medical Institute] under the leadership of Dr. Fernando Altamirano, who started pharmacological studies in this country. Later, trials of cardiovascular pharmacology were performed in the small laboratories of the cardiological unit at the General Hospital of Mexico City, on Dr. Ignacio Chávez' initiative. The Mexican botanical-pharmacological tradition persists alive and vigorous at the Instituto Nacional de Cardiología and other scientific institutions of the country. PMID:24960330

  10. Activation Analysis in Botany and Agriculture. Survey Paper

    The applications of activation analysis to the plant sciences are reviewed. In soil science the technique has only been used by a few workers but its potentialities are good. In particular, it offers a practical method of measuring the concentrations of trace elements such as Co, Cu, Mn, Mo, Se and Zn in the soil solution, which has rarely if ever been carried out by other techniques. It can also be used to determine phosphorus in the soil solution from phosphate-deficient soils, which cannot be done by current methods. In pure botany there have been many applications, mostly concerned with the behaviour of essential trace elements. The sensitivity of the method is adequate for the analysis not only of minute seeds but of embryos, endosperm and seed coats dissected from those seeds. Important developments include the use of the (n, α) reaction to determine boron, the (p, n) reaction to determine oxygen-18 in products of photosynthesis, and the detection of minute traces of organic phosphates on chromatograms. Most papers refer to seed plants, but there has been some work on fungi and about 20 elements have been determined in algae. Some of the latter elements could not have been determined by any other technique. There have been numerous applications in agriculture, though here the sensitivity of the method for essential trace elements has not been taken advantage of as much as might have been expected. There has, however, been particular interest in the determination of selenium, mainly because of the difficulty of using conventional analysis for the levels normally found in herbage and fertilizers. The determination of toxic residues, containing such elements as As, Br, CI, Hg or Ni is another application of great potential interest. In a recent intercomparison programme involving the analysis of standard kale, activation analysis has been shown to give results agreeing with those obtained by other techniques in all but one instance. The exception is the

  18. The role of forensic botany in crime scene investigation: case report and review of literature.

    Aquila, Isabella; Ausania, Francesco; Di Nunzio, Ciro; Serra, Arianna; Boca, Silvia; Capelli, Arnaldo; Magni, Paola; Ricci, Pietrantonio

    2014-05-01

    Management of a crime is the process of ensuring accurate and effective collection and preservation of physical evidence. Forensic botany can provide significant supporting evidences during criminal investigations. The aim of this study is to demonstrate the importance of forensic botany in the crime scene. We reported a case of a woman affected by dementia who had disappeared from nursing care and was found dead near the banks of a river that flowed under a railroad. Two possible ways of access to crime scene were identified and denominated "Path A" and "Path B." Both types of soil and plants were identified. Botanical survey was performed. Some samples of Xanthium Orientalis subsp. Italicum were identified. The fall of woman resulted in external injuries and vertebral fracture at autopsy. The botanical evidence is important when crime scene and autopsy findings are not sufficient to define the dynamics and the modality of death. PMID:24502402

  19. Afrikaans in Botany after 75 years of “Akademie” activities

    H. P. van der Schijff

    1985-03-01

    Full Text Available Just like the Afrikaans language itself, the use of Afrikaans as a technical language in Botany made meaningful progress during the last 75 years. It cannot, however, be divorced from the general use of Afrikaans by the Afrikaner in his daily contact with his non-Afrikaans speaking compatriots in all other spheres of activities, such as business, sports or politics. Unless Afrikaans as a spoken language can hold its own in a growing English-speaking community and world, it will not survive as a technical scientific language in Botany. As a technical language only, no language can hold its own. The publishing of scientific papers in international journals by Afrikaans-speaking scientists cannot be attributed to selfishness or a lack of appreciation for their mother tongue. It must also be seen as a means of enhancing the scientific image of his country and of the Afrikaner.

    2009-04-01

    The perspectives of residents are brought together in this assembly of statements concerning the management of hexachlorobenzene waste in Botany, a southeastern suburb of Sydney. The paper indicates how residents have responded as participants in public participation exercises, and the contribution made by lay experts in the search for a negotiated solution to the problems of legacy wastes. Resident comments on the role of independent scientific experts, on legal liability, and on the State Government sponsored Commission of Inquiry, indicate the deficit of resources faced by the local community. The paper provides insights into the status of citizen knowledge in environmental controversies and the pitfalls of participatory processes. PMID:18805623

  5. New categories for traditional medicine in the Economic Botany Data Collection Standard.

    Gruca, Marta; Cámara-Leret, Rodrigo; Macía, Manuel J; Balslev, Henrik

    2014-09-11

    The Economic Botany Data Collection Standard (EBDCS) has been successfully followed by ethnobotanists investigating plant uses in many parts of the world. However, we have encountered some cases in our study of traditional medicine where the standard seems incomplete and inaccurate when it is applied to plant uses of rural or indigenous societies in developing countries. We propose two categories to be added to the EBDCS: Cultural Diseases and Disorders, and Ritual/Magical Uses. Adding these categories, we believe will give a more accurate insight into traditional medicine and will contribute to developing an integrative ethnomedicinal data collection protocol, which will make ethnomedicinal studies more comparable.

  6. Training links and transmission of knowledge in 18th Century botany: a social network analysis

    René Sigrist

    2011-12-01

    Full Text Available This contribution develops a social network approach to the training of European botanists in the 18th century. In a period when the study of plants increasingly became an autonomous field of research, the practice of botany and related sciences mobilized a very diverse group of actors. For many of them, initiation to the science of plants was part of their medical studies. Others were trained as collaborators with an outstanding scholar in the context of a royal garden or elsewhere, sometimes also in philosophy colleges or faculties. Still others were self-taught. To the extent that biographical data were available, we made a systematic census of the masters and disciples of a set of 928 Western botanists active between 1700 and 1830. Three subsets were thus identified, each of them showing distinct characteristics and developmental patterns. The specific features of these subsets are discussed in a historical perspective, with a particular attention to the various institutional contexts which produced them. The data analysis basically shows the growing autonomy of botany with regard to medical training, as well as the increasingly national character of the dominant schools, at least in France.

  7. Platycladus orientalis leaves: a systemic review on botany, phytochemistry and pharmacology.

    Shan, Ming-Qiu; Shang, Jing; Ding, An-Wei

    2014-01-01

    Platycladus orientalis leaves (Cebaiye) have been used for thousands of years as traditional Chinese medicine (TCM). According to the theory of TCM, they are categorized as a blood-cooling and hematostatic herb. In clinical practice, they were usually prescribed with heat-clearing herbs to reinforce the efficacy of hemostasis. The review provides the up-to-date information from 1980 to present that is available on the botany, processing research, phytochemistry, pharmacology and toxicology of the leaves. The information is collected from scientific journals, books, theses and reports via library and electronic search (Google Scholar, Pubmed and CNKI). Through literature reports, we can find that the leaves show a wide spectrum of pharmacological activities, such as anti-inflammatory, antioxidant, antimicrobial, disinsection, anticancer, diuretic, hair growth-promoting, neuroprotective and antifibrotic activities. Diterpene and flavonoids would be active constituents in P. orientalis leaves. Many studies have provided evidence for various traditional uses. However, there is a great need for additional studies to elucidate the mechanism of blood-cooling and hematostatic activity of the leaves. Therefore, the present review on the botany, traditional uses, phytochemistry and toxicity has provided preliminary information for further studies of this herb. PMID:24871649

  8. The correspondence of Thomas Dale (1700-1750): Botany in the transatlantic Republic of Letters.

    Cook, William J

    2012-03-01

    This paper seeks to provide a full account of the life and career of Dr. Thomas Dale (1700-1750), with particular reference to his botanical works and correspondence. Born in Hoxton, London, Dale studied medicine at Leiden and engaged fully in the social, literary and epistolary network in which botany was practised in eighteenth-century England. In 1730, however, Dale relocated to the British colonial port of Charles Town, South Carolina. Here he continued to engage in a transatlantic network of botanical exchange and discussion, corresponding on equal and reciprocal terms with his former colleagues in England. Where Dale differs from naturalists in South Carolina before him is that his motives for pursuing botany and for corresponding with English naturalists were located firmly in the New World. Such a conclusion forms a valuable, albeit small contribution to models for the development of national scientific cultures in the imperial world. Similarly, Dale's pursuit of botanical information in South Carolina provides a small amount of material with which to illustrate currently fashionable models for the mediated exchange and circulation of scientific knowledge.

  9. General Botany of the Angiosperms in high school: a comparative analysis of textbooks

    Lucas Cardoso Marinho

    2015-12-01

    Full Text Available Much of the textbooks content in Brazil is related to the historical period lived. With the advancement in the field of scientific research, the textbooks have become key pieces in the transfer/adaptation of this knowledge for the basic levels of education influencing positively or negatively in approach and presentation of content. The purpose of this study was to examine comparatively how the contents of General Botany of the Angiosperms are approached in three biology textbooks of high school (1974, 1999 and 2011. The 1974 book have long texts that include an elaborated discussion and there is a tendency to simplify the content. The book of the 1999 presents the content in the form of direct and specific concepts split into separate chapters. In this work, the reduced form compromises the discussion, giving up themes that enrich the study. The book of the 2011 separate the content into different chapters and keeps reducing the content but without losing the quality and clarity of their information. Over the years, from the best understanding of the textbooks objectives and scientific research involving these documents, it is clear that the most current book is more attractive and less dense, contributing of the deconstruct the idea of a boring and decorative Botany.

  10. The supervision of environmental risk: the case of HCB waste or Botany/Randwick?

    James, Peggy

    2009-04-01

    The governance activities of capital and the state include attempts to control the timing and spacing of social activities such as the production of environmental risks and settlement of different social groups. The supervisory activities that have shaped the environmental and social history of the Botany/Randwick area are identified here, to examine how the HCB waste risk developed in that community. The analysis shows that multiple environmental risks and an ethnically diverse, working class community have been brought together in space to create environmental injustice. Analysing the governance of one environmental risk like hexachlorobenzene (HCB) waste may not increase understanding about communities facing multiple environmental risks or the supervisory processes that lead to the unfair accumulation of risks for particular places or social groups. Lessons from the environmental justice movement suggest that reframing problems like HCB waste management at Botany/Randwick as distributive justice issues may contribute to governance arrangements that better manage multiple risks and pollution sources in space affecting marginalised communities.

    Khalilian, Madjid; Boroujeni, Farsad Zamani; Mustapha, Norwati

    Nowadays the growth of the web causes some difficulties to search and browse useful information especially in specific domains. However, some portion of the web remains largely underdeveloped, as shown in lack of high quality contents. An example is the botany specific web directory, in which lack of well-structured web directories have limited user's ability to browse required information. In this research we propose an improved framework for constructing a specific web directory. In this framework we use an anchor directory as a foundation for primary web directory. This web directory is completed by information which is gathered with automatic component and filtered by experts. We conduct an experiment for evaluating effectiveness, efficiency and satisfaction.

  19. Forensic botany: species identification of botanical trace evidence using a multigene barcoding approach.

    Ferri, Gianmarco; Alù, Milena; Corradini, Beatrice; Beduschi, Giovanni

    2009-09-01

    Forensic botany can provide significant supporting evidence during criminal investigations. However, it is still an underutilized field of investigation with its most common application limited to identifying specific as well as suspected illegal plants. The ubiquitous presence of plant species can be useful in forensics, but the absence of an accurate identification system remains the major obstacle to the present inability to routinely and correctly identify trace botanical evidence. Many plant materials cannot be identified and differentiated to the species level by traditional morphological characteristics when botanical specimens are degraded and lack physical features. By taking advantage of a universal barcode system, DNA sequencing, and other biomolecular techniques used routinely in forensic investigations, two chloroplast DNA regions were evaluated for their use as "barcoding" markers for plant identification in the field of forensics. We therefore investigated the forensic use of two non-coding plastid regions, psbA-trnH and trnL-trnF, to create a multimarker system for species identification that could be useful throughout the plant kingdom. The sequences from 63 plants belonging to our local flora were submitted and registered on the GenBank database. Sequence comparison to set up the level of identification (species, genus, or family) through Blast algorithms allowed us to assess the suitability of this method. The results confirmed the effectiveness of our botanic universal multimarker assay in forensic investigations. PMID:19504263

  20. Information, power and environmental justice in Botany: the role of community information systems.

    Lloyd-Smith, Mariann

    2009-04-01

    In the environmental conflict that surrounds the sighting of hazardous waste facilities there is usually a volatile mix of disparities in power, expertise and information access as well as differing views on risk, which are all played out amidst commercial arrangements and environmental justice concerns. In recent times, the volatility of this mix has been further compounded by the growing climate of public concern and distrust surrounding scientific developments and technology. While there is no 'quick fix' to the complex conflict that this entails, community information systems (CISs) based on participatory models can help address the outstanding issues of capacity, information access, power inequities and environmental justice. CISs are an effective response to the five crucial elements of a toxic dispute, that is, the dialogue, capacity building, information access, evaluation of hazards and risk, and expertise. This paper will review the role of community accessible information systems in the dispute in Botany over the management and destruction of Orica Australia's stockpile of the persistent organic pollutant, hexachlorobenzene (HCB). It will focus on the role of CIS in responding to the challenges for expert information delivery, and in addressing the disparity of informational power within the toxic dispute. PMID:18804905

  1. The plant breeding industry after pure line theory: Lessons from the National Institute of Agricultural Botany.

    Berry, Dominic

    2014-06-01

    In the early twentieth century, Wilhelm Johannsen proposed his pure line theory and the genotype/phenotype distinction, work that is prized as one of the most important founding contributions to genetics and Mendelian plant breeding. Most historians have already concluded that pure line theory did not change breeding practices directly. Instead, breeding became more orderly as a consequence of pure line theory, which structured breeding programmes and eliminated external heritable influences. This incremental change then explains how and why the large multi-national seed companies that we know today were created; pure lines invited standardisation and economies of scale that the latter were designed to exploit. Rather than focus on breeding practice, this paper examines the plant varietal market itself. It focusses upon work conducted by the National Institute of Agricultural Botany (NIAB) during the interwar years, and in doing so demonstrates that, on the contrary, the pure line was actually only partially accepted by the industry. Moreover, claims that contradicted the logic of the pure line were not merely tolerated by the agricultural geneticists affiliated with NIAB, but were acknowledged and legitimised by them. The history of how and why the plant breeding industry was transformed remains to be written. PMID:24650856

  2. Forensic botany as a useful tool in the crime scene: Report of a case.

    Margiotta, Gabriele; Bacaro, Giovanni; Carnevali, Eugenia; Severini, Simona; Bacci, Mauro; Gabbrielli, Mario

    2015-08-01

    The ubiquitous presence of plant species makes forensic botany useful for many criminal cases. Particularly, bryophytes are useful for forensic investigations because many of them are clonal and largely distributed. Bryophyte shoots can easily become attached to shoes and clothes and it is possible to be found on footwear, providing links between crime scene and individuals. We report a case of suicide of a young girl happened in Siena, Tuscany, Italia. The cause of traumatic injuries could be ascribed to suicide, to homicide, or to accident. In absence of eyewitnesses who could testify the dynamics of the event, the crime scene investigation was fundamental to clarify the accident. During the scene analysis, some fragments of Tortula muralis Hedw. and Bryum capillare Hedw were found. The fragments were analyzed by a bryologists in order to compare them with the moss present on the stairs that the victim used immediately before the death. The analysis of these bryophytes found at the crime scene allowed to reconstruct the accident. Even if this evidence, of course, is circumstantial, it can be useful in forensic cases, together with the other evidences, to reconstruct the dynamics of events. PMID:26165654

    Full Text Available Barchewitz reached the islet of Leti, in the southwestern Moluccas, on September 2, 1714; he returned to Europe in September 1720, having represented the East India Company on Leti for six years. Like so many of his contemporaries he wrote a book on his life's adventures. This work appeared in 1730 and proved a success. A second, slightly enlarged, edition followed in 1751, entitled "Neu-vermehrte Ost-Indianische Reise- Beschreibung." Barchewitz is the earliest author on the natural history of Leti and -he paid attention to a number of plants. The present note is mainly a survey of the botany contained in his book. Ernst Christoph Barchewitz was born at the close of the 17th century at Grosz-Sommerda near Erfurt. He was bound apprentice to a tawer at Erfurt but soon preferred to travel ("Wanderschaft" with his brother to Holland. He visited the larger towns, learned at the Hague the art of dressing and the barber's craft, and became the valet de chambre of the Imperial Ambassador, Baron von Heems, whom he accompanied to Austria and the southern Netherlands. He ended his service at Delft Where he enlisted with the East India Company. As a soldier he embarked at Hellevoetsluis on the "Voorburg," sailing April 1, 1711. The treatment on board he judged to be fair; his only objection was that he had to drink water whereas wine would have seemed very suitable. After a stay at Batavia (December 20, 1711 till January 29, 1712, he was garrisoned on Banda, where he remained till August 15, 1714. He left when he was appointed Corporal of Leti. The following pertains to the second edition of Barchewitz's book, the pages referred to are cited between brackets. All quotations have been translated.

    高师院校的植物学教学应与非师范性大学的有所不同。它除了要培养学生的生命科学素养外,还要关注学生师范生素养的培养和提高。因此,高师院校的植物学教学除了要具备基础性、直观性和实践性等特征外,还要具备师范性特征。本文以华东师范大学生命科学学院的植物学实验教学为例,讲述如何实现这些特征的有效融合,希望为其他高师院校提供借鉴。%The teaching of botany in normal universities should be different from that in non - normal u- niversities. It should not only train students quality of life science, but also concern the cultivation and im- provement of normal students quality. Therefore, the teaching of botany in normal universities should be bas- ic, intuitive and practical. It also should tell the students how to be good teachers. The paper takes botany ex- perimental teaching in School of Life Science of East China Normal University for an example to tell how to a- chieve the integration of these features, looking forward to providing reference for other normal universities.

  19. Description of concept and first feasibility test results of a life support subsystem of the Botany Facility based on water reclamation

    Loeser, H. R.

    1986-01-01

    The Botany Facility allows the growth of higher plants and fungi over a period of 6 months maximum. It is a payload planned for the second flight of the Eureca platform around 1990. Major tasks of the Life Support Subsystem (LSS) of the Botany Facility include the control of the pressure and composition of the atmosphere within the plant/fungi growth chambers, control of the temperature and humidity of the air and the regulation of the soil water content within specified limits. Previous studies have shown that various LSS concepts are feasible ranging from heavy, simple and cheap to light, complex and expensive solutions. A summary of those concepts is given. A new approach to accomplish control of the temperature and humidity of the air within the growth chambers based on water reclamation is discussed. This reclamation is achieved by condensation with a heat pump and capillary transport of the condensate back into the soil of the individual growth chamber. Some analytical estimates are given in order to obtain guidelines for circulation flow rates and to determine the specific power consumption.

  20. Heritage of the romantic philosophy in post-Linnaean botany Reichenbach's reception of Goethe's metamorphosis of plants as a methodological and philosophical framework.

    Robin, Nicolas

    2011-01-01

    This paper demonstrates the importance of the reception and development of Goethe's metamorphosis of plants as a methodological and philosophical framework in the history of botanical theories. It proposes a focus on the textbooks written by the German botanist Ludwig Reichenbach and his first attempt to use Goethe's idea of metamorphosis of plants as fundamental to his natural system of plants published under the title 'Botany for Women', in German Botanik für Damen (1828). In this book, Reichenbach paid particular attention to Goethe's sensitive views on the essence of nature; he regarded Goethe's idea of metamorphosis in the plant kingdom as an ideal model to interpret connections of natural phenomena, in particular as a conceptual frame for a natural system. Furthermore, he aimed to develop the philosophical statement of the metamorphosis, in which he called for nature-philosophical conceptions in order to materialize his representation of plant "affinities," and of a kind of "ontogeny" of the whole plant kingdom. This paper demonstrates that, between speculative views and empirical attempts, the extent to which Reichenbach actually belonged to a new "school" of thought, which left its mark on the history and philosophy of botany.

    2011-10-01

    Full Text Available The study was conducted in a school of the black community of Furnas do Dionísio (Jaraguari, Mato Grosso do Sul State. For its realization, initially, a test with questions of botany was applied to the students to identify the absence or presence of subsumers classified into adequate or partially adequate. This analysis was used for the planning and production of instructional strategies in order to facilitate interaction between new information and background on the student's cognitive structure in order to promote learning. After, educational interventions have been proposed based on dialogue between traditional knowledge and science in the classroom. Based on the results of these strategies and concept maps based on the Theory of Meaningful Learning of David Ausubel, built by students on the proposed content, we concluded that learning was satisfactory. Taking into account the methodology used to investigate the local knowledge about medicinal plants, it is concluded that this contribution was significant to the learning of botany

  3. Botany in children's literature: A content analysis of plant-centered children's picture books that have a plot and characters

    Goins, Sheila Lewis

    This content analysis study examined 36 plant-centered children's science picture books that have a plot and characters published from 1950 to present. Botanical subject matter and learning opportunities offered by these books were analyzed, along with the range and frequency of the National Science Education Standards-consistent and age-appropriate plant science concepts and principles. The science graphics, artistic innovations, and story plot of these books were also examined. Rubrics and research-based recommendations were developed to offer parents, teachers, and librarians assistance in identifying, evaluating, and using such books to help children of ages 4--8 learn about plants and enjoy plant science. This genre of children's literature was identified and selected primarily through extensive research at four major, nationally recognized children's literature collections: The Kerlan Collection, The de Grummond Collection, The Center for Children's Books, and The Central Children's Room at the Donnell Library. This study determined that there was a substantial increase in the number of books written in this genre of children's literature from 1990 to 2000. Botanical subject-matter knowledge and learning opportunities offered by these books include biodiversity of plants; characteristics of plants; life cycles of plants; economic botany, ecology, and ethnobotany. The range and frequency of National Standards-consistent and age-appropriate plant science concepts and principles identified within these books, in part, though not exclusively, included the emergent categories of the process of photosynthesis; basic needs of plants; plant structures; external signals affecting plant growth; environmental stress to plants; biodiversity of plants; plants as animal habitats; and common uses of plants. With regard to plant science graphics, 13 books were identified as presenting some type of science graphic, beyond simple illustrations. The most frequently used

  6. The role of botany in the development of the Republic of South Africa with special emphasis on the contributions of the Botanical Research Institute

    D. J. B. Killick

    1979-12-01

    Full Text Available Five papers cover different aspects of the contributions to and role of botany in the development of the Republic of South Africa. Two papers sum up the contributions for the non-agricultural and agricultural sectors. The introductory paper by D. J. B. Killick provides a short historical account of the Botanical Research Institute, followed by a discussion of the contributions of the Institute to botany in South Africa through its National Herbarium and identification service as well as researches in taxonomy, plant anatomy, cyto-genetics, ecology, economic botany and data processing. B. de Winter emphasizes the fundamental role of taxonomy and bio-systematics for planning and the optimal use of the natural plant resources. The current support for taxonomy and biosystematics is examined and proposals made for improving progress in the Flora of Southern Africa series. For plant physiology, N. Grobbelaar discusses, firstly, the ways whereby the productivity of a plant species with its characteristic genetic constitution can be raised by determining and modifying for optimal response the effects of environmental factors such as spacing, mineral nutrition, water provision, etc.; and, secondly, usually when the first means has been achieved, of improving plant productivity by altering the genetic constitution of the plant so that it can perform better than its ancestors under the prevailing conditions. After discussing and illustrating the applications and roles of plant ecology, D. Edwards concludes that basic plant ecological research is required, firstly, at the regional level through regional plant ecological studies to supply the essential local knowledge needed by researchers, planners and users of the land; and, secondly, at the more detailed level where knowledge is needed of the processes and factors that govern the behaviour of vegetation so that it can be properly used, managed and manipulated.

  1. Marine botany. Second edition

    Dawes, C.J. [Univ. of South Florida, Tampa, FL (United States)

    1998-12-01

    Marine plants are a diverse group that include unicellular algae, seaweeds, seagrasses, salt marshes, and mangrove forests. They carry out a variety of ecological functions and serve as the primary producers in coastal wetlands and oceanic waters. The theme that connects such a wide variety of plants is their ecology, which was also emphasized in the 1981 edition. The goal of this revision is to present taxonomic, physiological, chemical, and ecological aspects of marine plants, their adaptations, and how abiotic and biotic factors interact in their communities. The data are presented in a concise, comparative manner in order to identify similarities and differences between communities such as salt marsh and mangroves or subtidal seaweeds and seagrasses. To accomplish this, the text is organized into five chapters that introduce the marine habitats, consider abiotic and biotic factors, and anthropogenic influences on the communities followed by seven chapters that deal with microalgae, seaweeds, salt marshes, mangroves, seagrasses, and coral reefs. Two appendixes are included; one presents simple field techniques and the other is a summary of seaweed uses.

  10. Palms do not undergo secondary stem lengthening: a response to Renninger and Phillips (American Journal of Botany 99: 607-613).

    Tomlinson, P Barry; Quinn, Christopher J

    2013-03-01

    Woody stems that have completed some maturation of metaxylem elements should not be capable of further axial extension ("secondary stem lengthening"). However, this mechanism has been claimed by Renninger and Phillips (American Journal of Botany 99: 607-613) to be a feature of the palm Iriartea deltoidea. In response, we describe structural features of palm stems based on extensive known features of their anatomy and development. In addition to the inability of metaxylem vessels to extend after they are mature, fully differentiated fibers of the vascular bundle sheath, which would exist at the time of proposed stem elongation would not be capable of belated extension. "Vessel spirals" claimed by these authors to be capable of stretching to accommodate secondary stem lengthening does not refer to well-established features of the course of vascular bundles. The approach adopted by Renninger and Phillips simply measures stems of different sizes as an implied developmental series. Consequently, results do not take into account changes in the development of the palm stem as it ages. The existence of secondary stem lengthening in the palm Iriartea deltoidea, something never before observed in any tree, cannot occur because it would indeed disrupt mature metaxylem vessels and would also require the secondary extension of mature lignified fibers.

    International Plant Proteomics Organization (INPPO) outlined ten initiatives to promote plant proteomics in each and every country. With greater emphasis in developing countries, one of those was to "organize workshops at national and international levels to train manpower and exchange information". This third INPPO highlights covers the workshop organized for the very first time in a developing country, India, at the Department of Botany in University of Delhi on December 26-30, 2013 titled - "1(st) Plant Proteomics Workshop / Training Program" under the umbrella of INPPO India-Nepal chapter. Selected 20 participants received on-hand training mainly on gel-based proteomics approach along with manual booklet and parallel lectures on this and associated topics. In house, as well as invited experts drawn from other Universities and Institutes (national and international), delivered talks on different aspects of gel-based and gel-free proteomics. Importance of gel-free proteomics approach, translational proteomics, and INPPO roles were presented and interactively discussed by a group of three invited speakers Drs. Ganesh Kumar Agrawal (Nepal), Randeep Rakwal (Japan), and Antonio Masi (Italy). Given the output of this systematic workshop, it was proposed and thereafter decided to be organized every alternate year; the next workshop will be held in 2015. Furthermore, possibilities on providing advanced training to those students / researchers / teachers with basic knowledge in proteomics theory and experiments at national and international levels were discussed. INPPO is committed to generating next-generation trained manpower in proteomics, and it would only happen by the firm determination of scientists to come forward and do it. PMID:25044573

  20. PARTE III DE HENSLOW A HOOKER: DARWIN Y LOS INICIOS DEL PENSAMIENTO EVOLUTIVO EN BOTÁNICA From Henslow to Hooker: Darwin and the Early Evolutionary Thought in Botany

    FAVIO GONZÁLEZ

    Full Text Available Aunque no lo suficientemente conocida y difundida, la obra botánica de Darwin aportó una gran cantidad de evidencia empírica fundamental para el establecimiento de la revolución darwinista. Se describe el desarrollo de esta obra, en especial con relación a los dos mentores de Darwin en botánica: J. S. Henslow y J. D. Hooker. Además de numerosos artículos y notas en sus diarios de viaje, su correspondencia y numerosos apartes de sus dos obras magnas El origen de las especies y selección natural, Darwin escribió siete libros relacionados con diversos aspectos de la botánica, incluída la polinización en orquídeas, la morfología y fisiología de plantas trepadoras, la domesticación, las plantas insectívoras, la polinización, las formas florales, y los movimientos de las plantas. Cada uno de estos libros es ahora clásico en cada tema. La introducción de la teoría evolutiva en la sistemática de plantas enriqueció los distintos sistemas de clasificación en los 70 años que siguieron a la publiación de El origen, lo cual está en estrecha relación con las preguntas, aún vigentes, acerca del origen y la diversificación temprana de las angiospermas. A la vez, se revisa la influencia de las contribuciones botánicas de Darwin en las obras de autores en diversos países de Europa y América, y en disciplinas tan diversas y actuales como la biogeografía, la biología reproductiva en muy diversos grupos de plantas con flor, la citología y mecanismos de herencia en la célula vegetal, la teratología vegetal, las variaciones debidas a domesticación, y la reciente integración de evolución, genética y desarrollo en la disciplina conocida como evo-devo.Despite Darwin s botanical works are not sufficiently known, they provided a large amount of critical, empirical evidence in favor of the darwinian revolution.

  5. Botany: Constraints to growth of boreal forests

    Jarvis, Paul; Linder, Sune

    2000-06-01

    Understanding how the growth of trees at high latitudes in boreal forest is controlled is important for projections of global carbon sequestration and timber production in relation to climate change. Is stem growth of boreal forest trees constrained by the length of the growing season when stem cambial cells divide, or by the length of the period when resources can be captured? In both cases, the timing of the thaw in the spring is critical: neither cambial cell division nor uptake of nutrients and carbon dioxide can occur while the soil is frozen. Here we argue, on the basis of long-term observations made in northern Saskatchewan and Sweden, that the time between the spring thaw and the autumn freeze determines the amount of annual tree growth, mainly through temperature effects on carbon-dioxide uptake in spring and on nutrient availability and uptake during summer, rather than on cambial cell division.

  6. DNA fingerprinting in botany: past, present, future.

    Nybom, Hilde; Weising, Kurt; Rotter, Björn

    2014-01-01

    Almost three decades ago Alec Jeffreys published his seminal Nature papers on the use of minisatellite probes for DNA fingerprinting of humans (Jeffreys and colleagues Nature 1985, 314:67-73 and Nature 1985, 316:76-79). The new technology was soon adopted for many other organisms including plants, and when Hilde Nybom, Kurt Weising and Alec Jeffreys first met at the very First International Conference on DNA Fingerprinting in Berne, Switzerland, in 1990, everybody was enthusiastic about the novel method that allowed us for the first time to discriminate between humans, animals, plants and fungi on the individual level using DNA markers. A newsletter coined "Fingerprint News" was launched, T-shirts were sold, and the proceedings of the Berne conference filled a first book on "DNA fingerprinting: approaches and applications". Four more conferences were about to follow, one on each continent, and Alec Jeffreys of course was invited to all of them. Since these early days, methodologies have undergone a rapid evolution and diversification. A multitude of techniques have been developed, optimized, and eventually abandoned when novel and more efficient and/or more reliable methods appeared. Despite some overlap between the lifetimes of the different technologies, three phases can be defined that coincide with major technological advances. Whereas the first phase of DNA fingerprinting ("the past") was dominated by restriction fragment analysis in conjunction with Southern blot hybridization, the advent of the PCR in the late 1980s gave way to the development of PCR-based single- or multi-locus profiling techniques in the second phase. Given that many routine applications of plant DNA fingerprinting still rely on PCR-based markers, we here refer to these methods as "DNA fingerprinting in the present", and include numerous examples in the present review. The beginning of the third phase actually dates back to 2005, when several novel, highly parallel DNA sequencing strategies were developed that increased the throughput over current Sanger sequencing technology 1000-fold and more. High-speed DNA sequencing was soon also exploited for DNA fingerprinting in plants, either in terms of facilitated marker development, or directly in the sense of "genotyping-by-sequencing". Whereas these novel approaches are applied at an ever increasing rate also in non-model species, they are still far from routine, and we therefore treat them here as "DNA fingerprinting in the future".

  11. Botany without borders: barcoding in focus.

    Kane, Nolan C; Cronk, Quentin

    2008-12-01

    This recent meeting, held on the campus of the University of British Columbia, attracted 1200 delegates and a vast array of talks, but was notable for a remarkable showing of talks and posters on DNA barcoding in plants, spread through many sessions. The Canadian Centre for DNA Barcoding defines barcoding as 'species identification and discovery through the analysis of short, standardized gene regions known as DNA barcodes'. This approach is somewhat controversial in animals (Rubinoff et al., 2006), although it has been shown to be useful and reliable in many metazoan taxa (Meyer & Paulay 2005; Hajibabaei et al., 2007), in which the mitochondrial cytochrome oxidase I (COI) gene is used. However, in land plants, COI evolves far too slowly to be useful, and there is no obvious single universal alternative (Fazekas et al., 2008).Genes that work well in one taxon may perform poorly in other taxa. Additionally, some perfectly good plant species,reproductively isolated and morphologically and ecologically distinct, are too young to show much sequence divergence at most loci. Nevertheless, as we saw at this conference, progress has been made towards identifying genes that serve many of the functions of DNA barcodes, at least in some plant taxa. PMID:19067801

  16. [Trehala, a meeting point between zoology, botany, chemistry, and biochemistry].

    Tillequin, François

    2009-07-01

    Trehala is a crude drug consisting of the pupal chambers formed by insects belonging to the genus Larinus that live on several Echinops species of the Middle-East. This sweet cocoon is locally used as human food and also for the treatment of cough and various pulmonary diseases. It first appeared in Western Europe in the collection of drugs from the Ottoman Empire displayed by François Della Sudda during the International Exhibition held in Paris in 1855. On the basis of this sample Nicolas Guibourt (1790-1867) gave, in 1858, the first full scientific description of the drug, its origin, and Larinus nidificans as the main insect species responsible for its formation. Marcellin Berthelot (1827-1907) isolated in the same year the sugar trehalose from the drug and gave a full account of its physical and chemical properties. In 1876, Müntz established that trehalose was identical with mycose isolated from Claviceps purpurea by Mitscherlich. PMID:20027793

  17. Collection and collation: theory and practice of Linnaean botany.

    Müller-Wille, Staffan

    2007-09-01

    Historians and philosophers of science have interpreted the taxonomic theory of Carl Linnaeus (1707-1778) as an 'essentialist', 'Aristotelian', or even 'scholastic' one. This interpretation is flatly contradicted by what Linnaeus himself had to say about taxonomy in Systema naturae (1735), Fundamenta botanica (1736) and Genera plantarum (1737). This paper straightens out some of the more basic misinterpretations by showing that: (1) Linnaeus's species concept took account of reproductive relations among organisms and was therefore not metaphysical, but biological; (2) Linnaeus did not favour classification by logical division, but criticized it for necessarily failing to represent what he called 'natural' genera; (3) Linnaeus's definitions of 'natural' genera and species were not essentialist, but descriptive and polytypic; (4) Linnaeus's method in establishing 'natural' definitions was not deductive, but consisted in an inductive, bottom-up procedure of comparing concrete specimens. The conclusion will discuss the fragmentary and provisional nature of Linnaeus's 'natural method'. I will argue in particular that Linnaeus opted for inductive strategies not on abstract epistemological grounds, but in order to confer stability and continuity to the explorative practices of contemporary natural history.

  19. Simaroubaceae family: botany, chemical composition and biological activities

    Iasmine A.B.S. Alves

    2014-08-01

    Full Text Available The Simaroubaceae family includes 32 genera and more than 170 species of trees and brushes of pantropical distribution. The main distribution hot spots are located at tropical areas of America, extending to Africa, Madagascar and regions of Australia bathed by the Pacific. This family is characterized by the presence of quassinoids, secondary metabolites responsible of a wide spectrum of biological activities such as antitumor, antimalarial, antiviral, insecticide, feeding deterrent, amebicide, antiparasitic and herbicidal. Although the chemical and pharmacological potential of Simaroubaceae family as well as its participation in official compendia; such as British, German, French and Brazilian pharmacopoeias, and patent registration, many of its species have not been studied yet. In order to direct further investigation to approach detailed botanical, chemical and pharmacological aspects of the Simaroubaceae, the present work reviews the information regarding the main genera of the family up to 2013.

    Zhang, Ru-Xue; Li, Mao-Xing; Jia, Zheng-Ping

    2008-05-01

    Rehmannia glutinosa, a widely used traditional Chinese herb, belongs to the family of Scrophulariaceae, and is taken to nourish Yin and invigorate the kidney in traditional Chinese medicine (TCM) and has a very high medicinal value. In recent decades, a great number of chemical and pharmacological studies have been done on Rehmannia glutinosa. More than 70 compounds including iridoids, saccharides, amino acid, inorganic ions, as well as other trace elements have been found in the herb. Studies show that Rehmannia glutinosa and its active principles possess wide pharmacological actions on the blood system, immune system, endocrine system, cardiovascular system and the nervous system. Currently, the effective monomeric compounds or active parts have been screened for the pharmacological activity of Rehmannia glutinosa and the highest quality scientific data is delivered to support the further application and exploitation for new drug development.

  6. Forensic botany: usability of bryophyte material in forensic studies.

    Virtanen, Viivi; Korpelainen, Helena; Kostamo, Kirsi

    2007-10-25

    Two experiments were performed to test the relevance of bryophyte (Plantae, Bryophyta) material for forensic studies. The first experiment was conducted to reveal if, and how well, plant fragments attach to footwear in general. In the test, 16 persons walked outdoors wearing rubber boots or hiking boots. After 24h of use outdoors the boots were carefully cleaned, and all plant fragments were collected. Afterwards, all plant material was examined to identify the species. In the second experiment, fresh material of nine bryophyte species was kept in a shed in adverse conditions for 18 months, after which DNA was extracted and subjected to genotyping to test the quality of the material. Both experiments give support for the usability of bryophyte material in forensic studies. The bryophyte fragments become attached to shoes, where they remain even after the wearer walks on a dry road for several hours. Bryophyte DNA stays intact, allowing DNA profiling after lengthy periods following detachment from the original plant source. Based on these experiments, and considering the fact that many bryophytes are clonal plants, we propose that bryophytes are among the most usable plants to provide botanical evidence for forensic investigations.

    This note explores two questions: (1) Which bigraded groups arise as the knot Floer homology of a knot in the three-sphere? (2) Given a knot, how many distinct knots share its Floer homology? Regarding the first, we show there exist bigraded groups satisfying all previously known constraints of knot Floer homology which do not arise as the invariant of a knot. This leads to a new constraint for knots admitting lens space surgeries, as well as a proof that the rank of knot Floer homology detec...

    1871-01-01

    The territory within which botanical collections have been nmade in connection with the United States Geological Survey of the 40th Parallel lies wholly within the limits of Northern Nevada and Utah. It forms a narrow tract at no point exceeding seventy miles in width, between the meridians of 111° and 120°, and extending frorn the parallel of 39° at the southwestern limit to that of 42° at the northeastern. This region constitutes the northern portion of what was at first designated as the "Great Basin" the high plateau, without outlet for its waters, separated on the north by low divides from the valley of the Snake River and continuing southward until it merges into the desert of the Lower Colorado. Geologically considered, however, as well as botanically, the term is now properly made to include the whole similar arid stretch of country northward to the plains of the Columbia in latitude 48°.

  5. Botany and a changing world: introduction to the special issue on global biological change.

    Weller, Stephen G; Suding, Katharine; Sakai, Ann K

    2013-07-01

    The impacts of global change have heightened the need to understand how organisms respond to and influence these changes. Can we forecast how change at the global scale may lead to biological change? Can we identify systems, processes, and organisms that are most vulnerable to global changes? Can we use this understanding to enhance resilience to global changes? This special issue on global biological change emphasizes the integration of botanical information at different biological levels to gain perspective on the direct and indirect effects of global change. Contributions span a range of spatial scales and include both ecological and evolutionary timescales and highlight work across levels of organization, including cellular and physiological processes, individuals, populations, and ecosystems. Integrative botanical approaches to global change are critical for the ecological and evolutionary insights they provide and for the implications these studies have for species conservation and ecosystem management.

  7. The geology, botany and chemistry of selected peat-forming environments from temperate and tropical latitudes

    Cameron, C.C.; Esterle, J.S.; Palmer, C.A.

    1989-01-01

    Peat has been studied in several geologic settings: (1) glaciated terrain in cold temperate Maine and Minnesota, U.S.A.; (2) an island in the Atlantic Ocean off the coast of Maine, where sea level is rising; (3) the warm temperate U.S. Atlantic and Gulf Coastal Plains, where sea level has changed often; and (4) the tropical coast of Sarawak, Malaysia, and the tropical delta of the Batang Hari River, Sumatra, Indonesia. Most of these deposits are domed (ombrotrophic or partly ombrotrophic) bogs in which peat accumulation continued above the surface of the surrounding soil. However, the bogs of the U.S. Atlantic and Gulf Coastal Plains are comparatively not as domed, and many have almost level surfaces. In some bogs, aquatic or semi-aquatic plant materials accumulated, replaced water in the depressions, and formed a surface on which marsh or swamp vegetation could subsequently live, die, and accumulate. In others, the plant materials accumulated initially on level silt or sand surfaces supporting marshes or swamps. As the peat dome formed, plants growing on it changed from luxuriant ones near the base of the dome, where nutrients were brought into the bog by surface and ground water, to stunted ones at the top of the dome, where the raised bogs are fed by nutrient-poor precipitation. The physical and chemical changes that take place in the sequence of environments from the pond stage of deposit development, through the grassy marsh stage, through the forested swamp stage, and finally through the heath dome stage can be measured in terms of acidity and ash, volatile matter, carbon, hydrogen, nitrogen, sulfur and oxygen contents, as well as in the kind and distribution of trace elements. The organic and inorganic contents of the deposits relate to geomorphology, and geomorphology relates to their settings. As models of coal formation, some domed peat deposits may help in solving problems of distribution and character of ancient coal beds. But clearly not all peat deposits are precursors of coal. Most Holocene peat deposits are subject to destruction by erosion, fire and decomposition through microbial and chemical oxidation before burial. The best environments for coal precursors have biomass accumulation, a continuously rising water table within the mass, and minimum influx of clay and silt until preservation by burial. The most suitable settings for future economic coal deposits are domed bogs that accumulate thick, widespread peat having low ash and low sulfur contents. The ombrotrophic peat deposits of tropical Sarawak and Sumatra are thick and extensive, contain low-ash and low-sulfur peat, and have high heating values. They are considered to be the best tropical coal analogs because of their extent and chances of preservation; the base of the peat is below adjacent river levels, and chemical and structural conditions are favorable for accumulation. ?? 1989.

  13. Linnaeus' restless system: translation as textual engineering in eighteenth-century botany.

    Dietz, Bettina

    2016-04-01

    In this essay, translations of Linnaeus' Systema naturae into various European languages will be placed into the context of successively expanded editions of Linnaeus' writings. The ambition and intention of most translators was not only to make the Systema naturae accessible for practical botanical use by a wider readership, but also to supplement and correct it, and thus to shape it. By recruiting more users, translations made a significant contribution to keeping the Systema up to date and thus maintaining its practical value for decades. The need to incorporate countless additions and corrections into an existing text, to document their provenance, to identify inconsistencies, and to refer to relevant observations, descriptions, and illustrations in the botanical literature all helped to develop and refine techniques of textual montage. This form of textual engineering, becoming increasingly complex with each translation cycle, shaped the external appearance of new editions of the Systema, and reflected the modular architecture of a botanical system designed for expansion.

  1. Botanical smuts and hermaphrodites: Lydia Becker, Darwin's botany, and education reform.

    Gianquitto, Tina

    2013-06-01

    In 1868, Lydia Becker (1827-1890), the renowned Manchester suffragist, announced in a talk before the British Association for the Advancement of Science that the mind had no sex. A year later, she presented original botanical research at the BAAS, contending that a parasitic fungus forced normally single-sex female flowers of Lychnis diurna to develop stamens and become hermaphroditic. This essay uncovers the complex relationship between Lydia Becker's botanical research and her stance on women's rights by investigating how her interest in evolutionary theory, as well as her correspondence with Charles Darwin, critically informed her reform agendas by providing her with a new vocabulary for advocating for equality. One of the facts that Becker took away from her work on Lychnis was that even supposedly fixed, dichotomous categories such as biological sex became unfocused under the evolutionary lens. The details of evolutionary theory, from specific arguments on structural adaptations to more encompassing theories on heredity (i.e., pangenesis), informed Becker's understanding of human physiology. At the same time, Becker's belief in the fundamental equality of the sexes enabled her to perceive the distinction between inherent, biological differences and culturally contingent ones. She applied biological principles to social constructs as she asked: Do analogous evolutionary forces act on humans? PMID:23961688

Apatani have traditionally settled in seven villages in the Ziro valley of Lower Subansiri district of Arunachal Pradesh in the Eastern Himalayan region of India. The present study has resulted in the documentation of 158 medicinal plant species used by the Apatani group of villages. These medicinal plant species were distributed across 73 families and 124 genera. Asteraceae was the most dominant family (19 species, 11 genera of medicinal plants, followed by Zingiberaceae, Solanaceae, Lamiaceae and Araceae. For curing ailments, the use of aboveground plant parts was higher (80% than the belowground plant parts in the Apatani group of villages. Of the aboveground plant parts, leaf was used in the majority of cases (56 species, followed by fruit. Different belowground plant forms such as root, tuber, rhizome, bulb and pseudo-bulb were used by Apatani as a medicine. About 52 types of ailments were cured by using these 158 medicinal plant species. The results of this study are further discussed in the changing socio-economic contexts.

  3. The geology, botany and chemistry of selected peat-forming environments from temperate and tropical latitudes

    Cameron, C.C.; Esterle, J.S.; Palmer, C.A. (US Geological Survey, Reston, VA (USA))

    1989-06-01

    Several peat forming deposits typical of temperate and tropical latitudes that were selected as representing principles of stratigraphic development are described. Their organic and inorganic contents are related to their geomorphology. The general nature of commercial-quality peat and its formation are briefly outlined. The stratigraphy of each peat deposit reflects a succession of peat-forming environments that can be identified with their modern-equivalent bogs, swamps and marshes. Types of peat in each deposit reflect the kind of peat-forming vegetation and degree of decomposition. Models and processes of peat accumulation are described to provide a frame of reference for understanding the geomorphology of the selected deposits. 64 refs., 15 figs., 5 tabs.

  6. A grass molecular identification system for forensic botany: a critical evaluation of the strengths and limitations.

    Ward, Jodie; Gilmore, Simon R; Robertson, James; Peakall, Rod

    2009-11-01

    Plant material is frequently encountered in criminal investigations but often overlooked as potential evidence. We designed a DNA-based molecular identification system for 100 Australian grasses that consisted of a series of polymerase chain reaction assays that enabled the progressive identification of grasses to different taxonomic levels. The identification system was based on DNA sequence variation at four chloroplast and two mitochondrial loci. Seventeen informative indels and 68 single-nucleotide polymorphisms were utilized as molecular markers for subfamily to species-level identification. To identify an unknown sample to subfamily level required a minimum of four markers or nine markers for species identification. The accuracy of the system was confirmed by blind tests. We have demonstrated "proof of concept" of a molecular identification system for trace botanical samples. Our evaluation suggests that the adoption of a system that combines this approach with DNA sequencing could assist the morphological identification of grasses found as forensic evidence.

    2013-04-01

    Full Text Available Aim: In spite of obsessive use of spices in every Ethiopian meal, little has been investigated on the utilization of Ethiopian spices as a cure for oral opportunistic infections. Therefore the aim was to identify spices used in Ethiopian food through ethno botanical survey and study their antifungal activity against Candida albicans. Method: Ethno botanical survey of the selected Kebeles of Jimma, Ethiopia was conducted using a semi structured questionnaire from October 2006 to November 2007. Antifungal nature of the spices and combination of spices and honey were evaluated by agar well diffusion assay from September 2008 to July 2010. Result: Ethno botanical survey indicated fourteen species of spices and honey play a major role in Ethiopian food and beverages. Single plant extract of Trachyspermum copticum showed highest activity against C. albicans. The same plant showed antagonistic effect when combined with brown and white honey. Cinamomum zeylanicum showed highest synergistic effect with both brown and white honey when compared to Allium ursenum, Cuminum cyminum, Nigella sativa, Rosemarinus officinalis and Occimum hodiense. Conclusion: Thus spices used in Ethiopian food could be a preventive as well as a cure for oral candidiasis caused by C.albicans. [J Intercult Ethnopharmacol 2013; 2(2.000: 73-80

  11. Botany, genetics and ethnobotany: a crossed investigation on the elusive tapir's diet in French Guiana.

    Fabrice Hibert

    Full Text Available While the populations of large herbivores are being depleted in many tropical rainforests, the importance of their trophic role in the ecological functioning and biodiversity of these ecosystems is still not well evaluated. This is due to the outstanding plant diversity that they feed upon and the inherent difficulties involved in observing their elusive behaviour. Classically, the diet of elusive tropical herbivores is studied through the observation of browsing signs and macroscopic analysis of faeces or stomach contents. In this study, we illustrate that the original coupling of classic methods with genetic and ethnobotanical approaches yields information both about the diet diversity, the foraging modalities and the potential impact on vegetation of the largest terrestrial mammal of Amazonia, the lowland tapir. The study was conducted in the Guianan shield, where the ecology of tapirs has been less investigated. We identified 92 new species, 51 new genera and 13 new families of plants eaten by tapirs. We discuss the relative contribution of our different approaches, notably the contribution of genetic barcoding, used for the first time to investigate the diet of a large tropical mammal, and how local traditional ecological knowledge is accredited and valuable for research on the ecology of elusive animals.

  15. A darker shade of green: medical botany, homeopathy, and cultural politics in interwar Germany.

    Kenny, Michael G

    2002-12-01

    In 1941 a proposal was made to Nazi SS Reichsführer, Heinrich Himmler, that extracts of a South American plant, Dieffenbachia seguine, might be used for the mass sterilization of racially undesirable war prisoners. The proposal was based on published animal fertility research conducted by Dr Gerhard Madaus, co-founder of a firm that produced and marketed natural medicinals. His fertility experiments were part of a broader series aimed at evaluating the scientific validity of ethnobotanical folk-knowledge. This article traces the historical background to the Madaus research: first, the role of homeopathy in the introduction of Dieffenbachias to western medicine; secondly, the social context of German 'alternative' medicine in the interwar period; and finally, the role of Madaus himself, whose homeopathically-oriented research on botanical medicinals inadvertently initiated the chain of events described here.

    Full Text Available The botanical and zoological references that appear in La Celestina are analysed and cuantified to provide an insight of the knowledge about plants and animals included in a literary work of the Rennaisance, in this case one of the most important of the Spanish literature. The plants and animals products were used by the healer for the care, health and beauty of the body. Many other plants, animals and some mineral products were used for love remedies. Moreover, references to plant and animal names and their products are also commented as linguistic sources, i.e. metaphoric references to plants, set phrases, and other literary figures of speech. All the 86 plant species and 70 animals and the complete textual passages are included in two apendixes.

    En este trabajo se analizan y cuantifican las referencias botánicas y zoológicas que aparecen en La Celestina como ejemplo de los conocimientos sobre plantas y animales que incorpora una obra de la literatura renacentista española. Dado el oficio de la protagonista, el interés del uso de muchas plantas y animales se centra en el cuidado, cura y aseo del cuerpo, que entonces se hacía sobre todo a base de productos vegetales y animales. Éstos también aparecen empleados en la magia de amor. Se comentan asimismo la utilización de nombres de plantas y animales, así como de productos derivados de éstos, como recursos lingüisticos o literarios; es decir, cuando se emplean como metáforas, en dichos, frases hechas y otras figuras literarias. Se incluyen en 2 anexos las 86 especies vegetales y las 70 animales, así como las citas encontradas.

  3. Inspiration in the harness of daily labor. Darwin, botany, and the triumph of evolution, 1859-1868.

    Bellon, Richard

    2011-09-01

    Charles Darwin hoped that a large body of working naturalists would embrace evolution after the Origin of Species appeared in late 1859. He was disappointed. His evolutionary ideas at first made painfully little progress in the scientific community. But by 1863 the tide had turned dramatically, and within five years evolution became scientific orthodoxy in Britain. The Origin's reception followed this peculiar trajectory because Darwin had not initially tied its theory to productive original scientific investigation, which left him vulnerable to charges of reckless speculation. The debate changed with his successful application of evolution to original problems, most notably orchid fertilization, the subject of a well-received book in 1862. Most of Darwin's colleagues found the argument of the Origin convincing when they realized that it functioned productively in the day-to-day work of science-and not before. The conceptual force of the Origin, however outwardly persuasive, acquired full scientific legitimacy only when placed "in the harness of daily labour". PMID:22073768

    2012-01-01

    We describe Solanum baretiaesp. nov., a new species of Solanum section Anarrhichomenum, named in honor of Jeanne Baret, who sailed as the assistant to botanist Philibert Commerson on Louis Antoine de Bougainville's global circumnavigation (1766-1769). The species is similar to Solanum chimborazense, but differs in having larger flowers, more flowers per inflorescence, and different patterns of pubescence on the filaments (pubescent adaxially and glabrous abaxially) and style (papillose to sparsely pubescent). A description, illustration, photos, and comparisons to similar species are included. Also included is a preliminary conservation assessment, along with a brief account of the important role played by Baret during the expedition. The new species appears to be restricted to the Amotape-Huancabamba zone, an area of southern Ecuador and northern Peru known for its exceptional biodiversity. PMID:22287929

  5. Botany and zoology in the late seventeenth-century Philippines: the work of Georg Josef Camel SJ (1661-1706).

    Reyes, Raquel A G

    2009-10-01

    Georg Josef Camel (1661-1706) went to the Spanish colony of the Philippine Islands as a Jesuit lay brother in 1687, and he remained there until his death. Throughout his time in the Philippines, Camel collected examples of the flora and fauna, which he drew and described in detail. This paper offers an overview of his life, his publications and the Camel manuscripts, drawings and specimens that are preserved among the Sloane Manuscripts in the British Library and in the Sloane Herbarium at the Natural History Museum, London. It also discusses Camel's links and exchanges with scientifically minded plant collectors and botanists in London, Madras and Batavia. Among those with whom Camel corresponded were John Ray, James Petiver, and the Dutch physician Willem Ten Rhijne. PMID:20014508

Vegetation appears as a living form of writing in nature that enablesmen and women to understand life and their relationship to the world. It can also beseen as the Grail that the alpinist sets out to find and that reveals the need to leaveplants in place and not destroy the environment for motives of profit. This paper aimsto show that the imagination may convey an ecological message and that ecologicalconsciousness may lead to metaphysical awareness.

  8. Preliminary results of sequential monitoring of simulated clandestine graves in Colombia, South America, using ground penetrating radar and botany.

    Molina, Carlos Martin; Pringle, Jamie K; Saumett, Miguel; Hernández, Orlando

    2015-03-01

    In most Latin American countries there are significant numbers of missing people and forced disappearances, 68,000 alone currently in Colombia. Successful detection of shallow buried human remains by forensic search teams is difficult in varying terrain and climates. This research has created three simulated clandestine burial styles at two different depths commonly encountered in Latin America to gain knowledge of optimum forensic geophysics detection techniques. Repeated monitoring of the graves post-burial was undertaken by ground penetrating radar. Radar survey 2D profile results show reasonable detection of ½ clothed pig cadavers up to 19 weeks of burial, with decreasing confidence after this time. Simulated burials using skeletonized human remains were not able to be imaged after 19 weeks of burial, with beheaded and burnt human remains not being able to be detected throughout the survey period. Horizontal radar time slices showed good early results up to 19 weeks of burial as more area was covered and bi-directional surveys were collected, but these decreased in amplitude over time. Deeper burials were all harder to image than shallower ones. Analysis of excavated soil found soil moisture content almost double compared to those reported from temperate climate studies. Vegetation variations over the simulated graves were also noted which would provide promising indicators for grave detection. PMID:25596556

  12. Antiquity, botany, origin and domestication of Jatropha curcas (Euphorbiaceae), a plant species with potential for biodiesel production.

    Dias, L A S; Missio, R F; Dias, D C F S

    2012-01-01

    Jatropha curcas is a multi-purpose plant species, with many advantages for biodiesel production. Its potential oil productivity is 1.9 t/ha, beginning the fourth year after planting. Nevertheless, limitations such as high harvest cost, lack of scientific konowledge and low profitability have prevented it from being utilized commercially. In order to provide information that could be useful to improve the status of this species as a bioenergy plant, we elucidated the center of origin and the center of domestication of J. curcas (Mexico). Evidence of the antiquity of knowledge of J. curcas by Olmeca people, who lived 3500-5000 years ago, reinforces its Mexican origin. The existence of non-toxic types, which only exist in that country, along with DNA studies, also strongly suggest that Mexico is the domestication center of this species. In Brazil, the Northern region of Minas Gerais State presents types with the highest oil content. Here we propose this region as a secondary center of diversity of J. curcas. PMID:22782638

  13. Getting the jump on Mother nature: the advancing technology of applied botany will speed reclamation of mined land

    1979-04-01

    By propagating native or indigenous plants in greenhouses on a speeded-up schedule, much guesswork is being taken out of revegetating mined land. Native Plants Inc., which tricks nature by reproducing the biological sequence of plants in a fraction of the natural time, offers reclaimers of disturbed land the plants they want in any quantity on very short notice. Prior to planting, seeds are treated to break their dormancy code. The plants are grown in tubepaks that promote root growth, grow both night and day, and have CO/sub 2/ injected into the air. The company reports a 97% success rate in transplanting its seedlings. Cloning and the unlocking of the germination secrets of plants have great potential for speeding the restoration of mined land. A micropropagation (or tissue culture), whereby parts of a whole plant are removed, sterilized, and grown on a specific nutrient medium are being considered. This technology affords a high degree of selectivity and rapid plant propagation and has far-reaching implications for mine operators faced with the challenges of reclaiming mined land. (DP)

    Full Text Available We describe Solanum baretiae sp. nov., a new species of Solanum section Anarrhichomenum, named in honor of Jeanne Baret, who sailed as the assistant to botanist Philibert Commerson on Louis Antoine de Bougainville’s global circumnavigation (1766–1769. The species is similar to S. chimborazense, but differs inlarger flowers, more flowers per inflorescence, and different patterns of pubescence on the filaments (pubescent adaxially and glabrous abaxially and style (papillose to sparsely pubescent. A description, illustration, photos, and comparisons to similar species are included. Also included is a preliminary conservation assessment, along with a brief account of the important role played by Baret during the expedition. The new species appears to be restricted to the Amotape-Huancabamba zone, an area of southern Ecuador and northern Peru known for its exceptional biodiversity.

  18. The natural history of Caroline Atoll, Southern Line Islands. Part I. History, physiography, botany, and isle descriptions

    Kepler, A.K.; Kepler, C.B.

    1994-01-01

    conclusion: Lushly wooded Caroline Atoll, with the majority of its 39 islets (399 ha of land) either in near-pristine condition or having recovered remarkably from past disturbance, is one of the least spoiled atolls in the Pacific. Uninhabited, it harbors plant ecosystems and breeding seabirds (Pt. II) of national and international importance. Its marine and terrestrial ecosystems are prime outdoor ecological laboratories for research on geological processes including ground water, sea level changes, the dynamics of motu formation, fish poisoning, and numerous facets of ecology including plant succession and Pisonia growth rates. Caroline boasts prime coral reefs thickly studded with Tridacna clams, substantial numbers of coconut crabs, breeding sites for green turtles, wintering grounds for shorebirds including the rare Bristle-thighed Curlew, ancient Tuamotuan marae, and a crystalline, unpolluted lagoon. The variety, abundance, and quality of its flora and fauna qualify it for status as an officially recognized international preserve (Pt. II, Sect. G). Efforts toward its conservation have thus far been unsuccessful: in 1992 it was leased to a private French businessman who is currently fishing the reefs for commercial profit, as well as disturbing seabird, turtle and coconut crab populations.

    Kaolin is an inert material with a broad range of applications, e.g. as an insecticide and as a filling substance in the formulation of biopesticides. Hence, bees that dispense biopesticides to the field in the context of entomovectoring are exposed to elevated risks because of sideeffects of those products. Here, we investigated with use of bumble bee workers of Bombus terrestris L. the lethal and sublethal effects of (i) pure kaolin, (ii) the biofungicide Prestop-Mix containing the parasiti...

    2010-06-01

    Full Text Available The journal Broteria has covered a long path, since its foundation in 1902 until the mid 20’s, when it stands as one of the best journals of natural history and a voice of the renewal of the natural sciences in Portugal. Broteria’s success was due, mainly, to the remarkable qualities of its founders and main editors: their working capacity, intellectual standards and perseverance as well as the ability to establish a network of naturalists who sent them biological collections from remote regions and the ability to adapt to exile, while continuing to work and focusing their studies on the natural history of the exile country. The maintenance, in regular functioning, of their schools, and the opening to the collaboration of non Jesuit naturalists, such as the botanists from Oporto, also contributed to the success of Broteria.

    La revista Broteria recorrió un largo camino, desde su fundación en 1902, hasta mediados de la década de 1920, cuando se consolida como una de las mejores revistas de historia natural y una voz de la renovación de las Ciencias Naturales en Portugal. El éxito de Broteria se debió, principalmente, a las notables calidades de sus fundadores y principales redactores: capacidad de trabajo, nivel intelectual y perseverancia; capacidad para establecer una red de naturalistas que les enviaban colecciones biológicas de regiones mal conocidas; capacidad de adaptación en el exilio continuando su trabajo y enfocando sus estudios en la historia natural del país de exilio. La manutención, en regular funcionamiento, de sus colegios y la apertura a la colaboración de naturalistas no jesuitas, especialmente a los botánicos de Oporto, también contribuyeron al éxito de Broteria. Los documentos epistolares tratados en este trabajo demuestran que A. Luisier, J.S. Tavares, y G. Sampaio lideraron una red de jesuitas naturalistas y botánicos de Oporto, que intercambiaron plantas e ideas. Este intercambio fue determinante en el estudio de la flora de musgos y plantas vasculares portuguesas y el progreso de los Herbarios de los colegios jesuitas y de la Academia Politécnica de Oporto.

  12. A discussion on discordant whole rock Rb/Sr and fine fraction K-Ar dates from Trinity Peninsula group at Botany Bay, West Antarctica

    The term Trinity Peninsula Series (Adie, 1957) has been applied to a variety of deformed sedimentary rocks throughout the Antarctic Peninsula area. Different authors have carried out several studies (Croft, 1947, Bibby, 1965, Hyden and Tanner, 1981 and others). It has been considered as a flysch-like turbidite and greywacke sequence accumulated in a subduction-related accretionary prism. Hyden and Tanner (1981) re-examined the Trinity Peninsula Group (TPG) in the type area and divided it into the Hope Bay, View Point and Legoupil Formations. The TPG was assigned from the Carboniferous to the Triassic on the basis of geochronological and geological studies (Herve 1992; Loske and Miller, 1991; Trouw et al., 1995). Miller and Loske (1992), consider that the depositional age of the TPG is not older than late Carboniferous and Trouw et al. (1995) have obtained Triassic Rb-Sr ages for the north-west of Antarctic Peninsula in associated sequences. The aim of this work is to discuss the discordant dates obtained from two different geochronological methods, with a comparison between K-Ar dating on fine fractions (used successfully by other authors as Clauer, 1981; Bonhomme, 1982 and Kralik, 1983 to determine the age of the low grade metamorphic events) and Rb/Sr whole rock dating, which also has been used with the same purpose (author)

    Polar isolates of four chlorococcal microalgae originating from the Arctic and Antarctica withstand cryopreservation using encapsulation-dehydration. Viability assessments, which initially used chloroplhyll fluorescence (Kautsky) induction kinetics, revealed that all strains suffered photosynthetic impairment during early post-cryopreservation recovery. This cryoinjury was reversible, as indicated by cell regrowth in three of the four strains. Lack of growth in the fourth isolate was due to contaminating bacteria rather than cryogenic factors.

  8. Tropical Epiphytic Orchids as an Object of Space Botany Investigations and a Design Element for Spacecraft Flight Decks and Orbital Stations

    Cherevchenko, T. M.; Zaimenko, N. V.

    Epiphytic orchids are shown to be more stable in a long stay on board an orbital station than terrestrial species. Simulations revealed that the activity of native growth stimulators (free auxins and gibberellines) under the prolonged clinostating conditions varied in epiphytic orchids to a lesser extent than in terrestrial orchids. This factor, together with a weaker geotropic reaction, seems to be a cause of their stability in microgravitation conditions. The authors found also that orchids with the monopodial type of shoot system branching are less stable at microgravity than the sympodial species.

  10. Uncovering patterns of interest in useful plants. Frequency analysis of individual students’ interest types as a tool for planning botany teaching units

    Peter Pany

    2014-12-01

    Full Text Available The paper presented examines how useful plants can help counteracting “plant blindness” – a phenomenon leading people to overlook plants in everyday-life. Recent research indicates that people are most likely interested in useful plants, hence this group of plants could be used to trigger interest in botanical content in general. This study has investigated the structure of interest in five subgroups of useful plants (medicinal plants, stimulant herbal drugs, spice plants, edible plants, and ornamental plants. For this purpose, the FEIN-questionnaire (Fragebogen zur Erhebung des Interesses an Nutzpflanzen = Questionnaire acquiring interest in useful plants was filled in by N = 1299 pupils from grade 5 to 12. Data analysis shows (for all age groups and both genders that medicinal plants and stimulant herbal drugs trigger high interest while spice plants, edible plants and ornamental plants raise only lower interest. However, mean values do not allow conclusions on individual level (e.g. in a school class. In order to gain information about the interest structure in a specific target group teachers deal with in practice, we have analysed the interests on individual level using frequency analysis of different interest types. Results show that stimulant herbal drugs seem to strongly polarize students, whereas medicinal plants are interesting for almost the whole sample. Eventually, medicinal plants turned out to be well suited to introduce botanical content by means of plants catching the interest of as many students as possible. Therefore, medicinal plants should be established as flagships counteracting plant blindness.

  3. [The journal "Broteria," Jesuit botanists and Gonçalo Sampaio. Exchange of plants and ideas, and the development of botany in Portugal].

    Cabral, João Paulo

    2010-01-01

    The journal Broteria has covered a long path, since its foundation in 1902 until the mid 20's, when it stands as one of the best journals of natural history and a voice of the renewal of the natural sciences in Portugal. Broteria's success was due, mainly, to the remarkable qualities of its founders and main editors: their working capacity, intellectual standards and perseverance as well as the ability to establish a network of naturalists who sent them biological collections from remote regions and the ability to adapt to exile, while continuing to work and focusing their studies on the natural history of the exile country. The maintenance, in regular functioning, of their schools, and the opening to the collaboration of non Jesuit naturalists, such as the botanists from Oporto, also contributed to the success of Broteria.

    Gierl, Martin

    2010-01-01

    In the middle of the eighteenth century, Carl von Linné, Johann Christoph Gatterer, and Christian Wilhelm Büttner attempted to realize the old idea of deciphering the alphabet of the world, which Francis Bacon had raised as a general postulate of science. This article describes these attempts and their interrelations. Linné used the model of the alphabet to classify plants according to the characters of this fruiting body. Gatterer, one of the leading German historians during the Enlightenment, adopted the botanical method of classification by genus and species to classify the history of scripts. He used the forms of the alphabetic characters to measure the age of manuscripts and to map the process of history as a genealogy of culture. Gatterer collaborated closely with Büttner, the first Göttingen professor of natural history. Büttner constructed a general alphabet of languages which connected the phonetics of language with the historically known alphabets. Early on, diplomatics and ethnography combined the natural order of natural history and the cultural order of the alphabet with the attempt to register development and to document development by the evolution of forms. Based on the shared model of the alphabet and on the common necessity to classify their empirical material, natural history and the description of culture were related attempts in the middle of the eighteenth century to comprehend the alphabetically organized nature and a naturally ordered culture.

  1. Nomenclatural and taxonomic problems related to the electronic publication of new nomina and nomenclatural acts in zoology, with brief comments on optical discs and on the situation in botany.

    Dubois, Alain; Crochet, Pierre-André; Dickinson, Edward C; Nemésio, André; Aescht, Erna; Bauer, Aaron M; Blagoderov, Vladimir; Bour, Roger; De Carvalho, Marcelo R; Desutter-Grandcolas, Laure; Frétey, Thierry; Jäger, Peter; Koyamba, Victoire; Lavilla, Esteban O; Löbl, Ivan; Louchart, Antoine; Malécot, Valéry; Schatz, Heinrich; Ohler, Annemarie

    2013-01-01

    In zoological nomenclature, to be potentially valid, nomenclatural novelties (i.e., new nomina and nomenclatural acts) need first to be made available, that is, published in works qualifying as publications as defined by the International Code of zoological Nomenclature ("the Code"). In September 2012, the Code was amended in order to allow the recognition of works electronically published online after 2011 as publications available for the purpose of zoological nomenclature, provided they meet several conditions, notably a preregistration of the work in ZooBank. Despite these new Rules, several of the long-discussed problems concerning the electronic publication of new nomina and nomenclatural acts have not been resolved. The publication of this amendment provides an opportunity to discuss some of these in detail. It is important to note that: (1) all works published only online before 2012 are nomenclaturally unavailable; (2) printed copies of the PDFs of works which do not have their own ISSN or ISBN, and which are not obtainable free of charge or by purchase, do not qualify as publications but must be seen as facsimiles of unavailable works and are unable to provide nomenclatural availability to any nomenclatural novelties they may contain; (3) prepublications online of later released online publications are unavailable, i.e., they do not advance the date of publication; (4) the publication dates of works for which online prepublications had been released are not those of these prepublications and it is critical that the real release date of such works appear on the actual final electronic publication, but this is not currently the case in electronic periodicals that distribute such online prepublications and which still indicate on their websites and PDFs the date of release of prepublication as that of publication of the work; (5) supplementary online materials and subsequent formal corrections of either paper or electronic publications distributed only online are nomenclaturally unavailable; (6) nomenclatural information provided on online websites that do not have a fixed content and format, with ISSN or ISBN, is unavailable. We give precise examples of many of these nomenclatural problems. Several of them, when they arise, are due to the fact that the availability of nomenclatural novelties now depends on information that will have to be sought not from the work itself but from extrinsic evidence. As shown by several examples discussed here, an electronic document can be modified while keeping the same DOI and publication date, which is not compatible with the requirements of zoological nomenclature. Therefore, another system of registration of electronic documents as permanent and inalterable will have to be devised. ZooBank also clearly needs to be improved in several respects. Mention in a work of its registration number (LSID) in ZooBank would seem to be possible only if this registration has occurred previously, but some works that have purportedly been registered in ZooBank are in fact missing on this web application. In conclusion, we offer recommendations to authors, referees, editors, publishers, libraries and the International Commission on Zoological Nomenclature, in the hope that such problems can be limited along with the potential chaos in zoological nomenclature that could result, if careful attention is not paid to the problems we highlight here, from a somewhat misplaced, and perhaps now widespread, understanding that electronic publication of nomenclatural novelties is now allowed and straightforward. We suggest that, as long as the problematic points linked to the new amendment and to electronic publication as a whole are not resolved, nomenclatural novelties continue to be published in paper-printed journals that have so far shown editorial competence regarding taxonomy and nomenclature, which is not the case of several recent electronic-only published journals.

  18. Plants from Abroad: Botanical Terminology in 18th-century British Encyclopaedias

    Elisabetta Lonati

    2013-11-01

    Full Text Available During the 18th century British encyclopaedias included in their lemmata an increasing number of botanical lexis, that is the terminology pertaining to “that branch of natural history which treats of the uses, characters, classes, orders, genera, and species of plants. […] and what useful and ornamental purposes may be expected from the cultivation of it [i.e. botany]” (Encyclopaedia Britannica, 1768-1771, s.v. Botany. More often than not, these terms represented migrating plants coming from exotic places, new geographical areas, whether eastwards or westwards.The general aim of this survey is to investigate the representation of the botanical science in 18th-century universal and specialized encyclopaedias, starting from prefaces and going on with the micro-texts of the single entries s.v. Botany. The starting point is thus theoretical botany. A further point in the analysis focuses on applied botany and discusses those plants such as Camellia Sinensis, Coffea Arabica, Theobroma Cacao, Saccharum Officinarum and Cinchona Officinalis which were mostly exploited for commercial and/or medical reasons.The individual entries include the most tiny details on the single headwords-topics and also display an acceptable plurality of beliefs, viewpoints and perspectives, focussing on botanical descriptions, historical information, socio-cultural issues, legal, political and commercial considerations.

  19. Carl Linnaeus, Erasmus Darwin and Anna Seward: Botanical Poetry and Female Education

    George, Sam

    2014-03-01

    This article will explore the intersection between `literature' and `science' in one key area, the botanical poem with scientific notes. It reveals significant aspects of the way knowledge was gendered in the Enlightenment, which is relevant to the present-day education of girls in science. It aims to illustrate how members of the Lichfield Botanical Society (headed by Erasmus Darwin) became implicated in debates around the education of women in Linnaean botany. The Society's translations from Linnaeus inspired a new genre of women's educational writing, the botanical poem with scientific notes, which emerged at this time. It focuses in particular on a poem by Anna Seward and argues that significant problems regarding the representation of the Linnaean sexual system of botany are found in such works and that women in the culture of botany struggled to give voice to a subject which was judged improper for female education. The story of this unique poem and the surrounding controversies can teach us much about how gender impacted upon women's scientific writing in eighteenth century Britain, and how it shaped the language and terminology of botany in works for female education. In particular, it demonstrates how the sexuality of plants uncovered by Linnaeus is a paradigmatic illustration of how societal forces can simultaneously both constrict and stimulate women's involvement in science. Despite the vast changes to women's access in scientific knowledge of the present day, this `fair sexing' of botany illustrates the struggle that women have undergone to give voice to their botanical knowledge.

They were the first to bring, from their voyages, the information about use of plants in native populations. However, the 19 century brings the precision, scrutiny and accuracy in research. It was in 1873 that the term "aboriginal botany" was used the first time in academia, and only a few years later the new term "ethno-botany" w...

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

    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.

    Bediaga, Begonha; Peixoto, Ariane Luna; Filgueiras, Tarciso S

    2016-01-01

    This article sheds light on Maria Bandeira, the first female botanist to work at the Botanic Garden of Rio de Janeiro. She was active in the 1920s, but is absent from the historiography and little cited in the scientific literature. The significant number of plant, fungus, and lichen specimens she collected, her capacity to reach far-flung places, her extensive correspondence with foreign experts, and her studies at Sorbonne are all sources for the analysis of the way botany was practiced and the social networks at play in science at the time. The end of her scientific career, when she adopted a cloistered life with the Barefoot Carmelite nuns, can be interpreted variously, and partially explains why her contributions to Brazilian botany have been forgotten.

  20. Historical perspective on the moon base: the British experience

    Among the many historical episodes that have relevance to the establishment of a human base, the voyages of Captain Cook, and the founding of Britain's Botany Bay colony in Australia seems particularly appropriate. The process resulting in the selection of Cook rewards study, as do his relations with the Admiralty, with the scientific establishment and with the scientists who accompanies him. Britain's tight control of the Botany Bay settlement and its unwillingness to promote early self-sufficiency may have delayed the time when Australia became self-supporting. Structuring the lunar base to offer opportunities for private initiatives may hasten the day when it becomes a self-supporting settlement rather than an externally supported scientific base on an Antarctic model

Simultaneous hermaphrodites can function in both male and female roles whereas a dioecious/gonochorist population consists of distinct male and female individuals. Mean-field calculations, which ignore spatial aspects, suggest that self-incompatible hermaphrodites should have a twofold advantage over dioecious population when reproduction is limited by ma...

    2008-01-01

    The origin of the sporophyte in land plants represents a fundamental phase in plant evolution. Today this subject is controversial, and scarcely considered in textbooks and journals of botany, in spite of its importance. There are two conflicting theories concerning the origin of the alternating generations in land-plants: the “antithetic” theory and the “homologous” theory. These have never been fully resolved, although, on the ground of the evidences on the probable ancestors of land plants...

    During the time of Darwin, when biological evolution was accepted among scientists,natural history developed from a descriptive study of nature to scientific research tostudy the diversity, structure and history of nature. This development, however, caused natural history to be definitely reduced to its organizational units, zoology, botany, geology, mineralogy, etc, and later to further smaller units. In the 20th century, each smaller unit achieved great success under reductionism, but it be...

    The green house based experiments were conducted in the Department of Botany FUUAST, Karachi to study the allelopathic effects of root and shoot leachates of Anagallis arvensis on the two test species viz., bajra and mungbean. The percentage of seed germination, speed of germination and radical elongation of the test species were recorded after 10 days. Both leachates have no effect on seed germination and speed of germination of the test species. Radical elongation of two test species showed different response. Mung radical growth was significantly reduced while bajra radical growth was significantly enhanced by the root leachate of weed. (author)

  19. On knots in overtwisted contact structures

    Etnyre, John B

    2010-01-01

    We prove that each overtwisted contact structure has knot types that are represented by infinitely many distinct transverse knots all with the same self-linking number. In some cases, we can even classify all such knots. We also show similar results for Legendrian knots and prove a "folk" result concerning loose transverse and Legendrian knots (that is knots with overtwisted complements) which says that such knots are determined by their classical invariants (up to contactomorphism). Finally we discuss how these results partially fill in our understanding of the "geography" and "botany"' problems for Legendrian knots in overtwisted contact structures, as well as many open questions regarding these problems.

    2016-04-01

    During the Middle Ages and Renaissance, embalming the cadaver of the elite was common practice, being a highly technical treatment mixing vegetal and mineral substances. To assess the exact kind of embalming reserved for the dead body (with the practical necessities of desiccation and good odour), we performed a full biomedical analysis of the mummified remains of John Plantagenet of Lancaster, first Duke of Bedford, regent of France for his nephew, the English King Henri VI (died 1435 AD). Here, we show, among other aspects, that the body was embalmed using substances whose origins were in apothecary and botany: mercury, myrtle, mint, frankincense, lime and, possibly, cinnamon and copper.

    Many studies have been made on the exact data of the introduction of Greek sciences to the Arabic culture. During the 8th and 9th centuries A.D. a big progress was done in the Arab-Islamic sciences, when the Caliphs of the Omayad and Abbasid dynasties invited many scientists, researchers and translators for translation of all sciences into Arabic. The Arabs paid special attention to the Greek natural sciences such as botany and pharmacy. Greek materia medica was a major common basis for Arab-Islamic medicine and pharmacy which in turn paved the way to the modern pharmaceutical therapy. PMID:12575695

    Permafrost soils contain approximately1700 Pg of carbon (C), twice the amount of C in the atmosphere. Temperatures in higher latitudes are increasing, inducing permafrost thaw and subsequent microbial decomposition of previously frozen C. This process is one of the most likely positive feedbacks to climate change. Understanding the temperature sensitivity (Q10) and dynamics of SOM decomposition under warming is essential to predict the future state of the earth - climate system. Alaskan tundra soils were exposed to two winter warming (WW) seasons in the field, which warmed the soils by 4°C to 40 cm depth. Soils were obtained from three depths (0 - 15, 15 - 25 and 45 - 55 cm) and differed in initial amounts of labile and recalcitrant C. Soils were incubated in the lab under aerobic conditions, at 15 and 25°C over 365 days. Q10 was estimated at 14, 100 & 280 days of incubation (DOI); C fluxes were measured periodically and dynamics of SOM decomposition (C pool sizes and decay rates) were estimated by fitting a two pool C model to cumulative respired C (Ccum, mgC/ginitialC). After two WW seasons, initial C content tended to decrease through the soil profile and C:N ratio was significantly decreased in the top 15 cm. After one year of incubation, Ccum was twice as high at 25°C as at 15°C and significantly decreased with depth. No significant WW field treatment was detected, although Ccum tended to be lower in warmed soils. Labile C accounted for up to 5% of initial soil C content in the top 15 cm and decreased with depth. Soils exposed to WW had smaller labile C pools, and higher labile C decay rates in the top 25 cm. Q10 significantly decreased with time and depth as labile pool decreased, especially for WW. This decrease with time indicates a lower temperature sensitivity of the most recalcitrant C pool. The deepest WW soil layer, where warming was more pronounced, had significantly lower Q10 compared to control soils at the same depth. After two seasons, the warming treatment affected decomposition by reducing labile C pools and increasing its decay rates. Warming also reduced temperature sensitivity, showing acclimation of the most recalcitrant C pool in the tundra ecosystem.

  14. Stachys lavandulifolia Vahl. and its Relation With Marmazad Activities in Traditional Manuscripts

    Minae, Bagher; Sardari, Mehdi; Sharifi, Hossein; Sedigh Rahim Abadi, Massih; Sadeghpour, Omid

    2015-01-01

    Context: In modern phytotherapy, Stachys lavandulifolia Vahl., a type of Stachys also known as Mountain Tea (Chay-e-Kouhi) has been widely studied based on its botanical and therapeutic characteristics over the recent decades. Evidence Acquisition: The present study investigated morphology, botanical characteristics, and some therapeutic activities of this plant and compares them with those of Marmazad, as the traditional equivalent of Stachys in traditional iranian medicine (TIM), to evaluate the similarities between Stachys and Marmazad. Results: In this study by exploring morphology, botanical properties and therapeutic activities of Stachys from modern botany and Marmazad in TIM, comparing them and considering similarities between those botanical properties and some of therapeutic activities this outcome was drawn that what had been known as Marmazad in TIM nowadays is equal to Stachys or Chay-e-Kouhi in modern botany. Conclusions: The achieved findings from this comparison between botanical characteristics and therapeutic activities of Stachys based on modern researches and those of Marmazad by referring to traditional manuscripts revealed significant similarities between them. Also, there were some applications mentioned for Marmazad in TIM which could help new researchers in modern phytotherapy to deal with those dimensions of this herb which are not worked out yet.

  15. Reusable Reentry Satellite (RRS) system design study: System cost estimates document

    1991-01-01

    The Reusable Reentry Satellite (RRS) program was initiated to provide life science investigators relatively inexpensive, frequent access to space for extended periods of time with eventual satellite recovery on earth. The RRS will provide an on-orbit laboratory for research on biological and material processes, be launched from a number of expendable launch vehicles, and operate in Low-Altitude Earth Orbit (LEO) as a free-flying unmanned laboratory. SAIC's design will provide independent atmospheric reentry and soft landing in the continental U.S., orbit for a maximum of 60 days, and will sustain three flights per year for 10 years. The Reusable Reentry Vehicle (RRV) will be 3-axis stabilized with artificial gravity up to 1.5g's, be rugged and easily maintainable, and have a modular design to accommodate a satellite bus and separate modular payloads (e.g., rodent module, general biological module, ESA microgravity botany facility, general botany module). The purpose of this System Cost Estimate Document is to provide a Life Cycle Cost Estimate (LCCE) for a NASA RRS Program using SAIC's RRS design. The estimate includes development, procurement, and 10 years of operations and support (O&S) costs for NASA's RRS program. The estimate does not include costs for other agencies which may track or interface with the RRS program (e.g., Air Force tracking agencies or individual RRS experimenters involved with special payload modules (PM's)). The life cycle cost estimate extends over the 10 year operation and support period FY99-2008.

  16. Occurrence of Rare Tree and Shrub Species in Hungary

    BARTHA, Dénes

    2005-01-01

    Full Text Available The Department of Botany has been focusing on investigating rare taxa of theHungarian dendroflora since 1989. The research dealt with nearly 50 species regarding conditions of occurrence, habitat preference, reproduction and possible conservational management up to 2003. In the investigation of species, chorology was of primary importance. Since 1993 occurrence data have been systematically collected. As a first result, CEU grid-maps of 142 species, including all the rare dendrotaxa in Hungary, were published (Bartha – Mátyás 1995 using grid squares of 10' long. × 6' lat. equalling approx. 12 × 11 km. With organizational and methodological experience, focuses have moved to processing, correction and mapping of reference, herbaria and new field records. A detailed evaluation of the distribution of 34 rare species in Hungary was made and published (Bartha et al 1999. The Department of Botany at the University of West Hungary has been project coordinator of ‘Floristic Mapping of Hungary’ since 2001. The present study describes actual distribution maps of 20 rare tree- and shrub species with short analyses of their conditions in Hungary.

  17. Dynamic estuarine plumes and fronts: importance to small fish and plankton in coastal waters of NSW, Australia

    Kingsford, M. J.; Suthers, I. M.

    1994-05-01

    In 1990, low density estuarine plumes in the vicinity of Botany Bay, Australia, extended up to 11 km across a narrow continental shelf ( ca 25 km) on ebb tides. The shape and seaward extent of plumes varied according to a combination of state of the tide, freshwater input and the direction and intensity of coastal currents. Offshore plumes dissipated on the flood tide and fronts reformed at the entrance of Botany Bay. Major differences in the abundance and composition of ichthyoplankton and other zooplankton were found over a 400-800 m stretch of water encompassing waters of the plume, front and ocean on seven occasions. For example, highest abundances of the fishes Gobiidae, Sillaginidae, Gerreidae and Sparidae as well as barnacle larvae and fish eggs were found in plumes. Cross-shelf distribution patterns of zooplankton, therefore, are influenced by plumes. Distinct assemblages of plankters accumulated in fronts, e.g. fishes of the Mugilidae and Gonorynchidae and other zooplankters (e.g. Jaxea sp.). Accumulation in fronts was variable and may relate to variable convergence according to the tide. We argue that plumes provide a significant cue to larvae in coastal waters that an estuary is nearby. Moreover, although many larvae may be retained in the turbid waters of plumes associated with riverine input, larvae are potentially exported in surface waters on ebb tides.

  18. Women's Engagement in Science Popularization and Research in Botany(1760--1830)%女性与植物学的传播和发展(1760-1830)

    姜虹

    2012-01-01

    During the 18th century, when enlightenment science became a cultural fashion in Europe, Linnaeus's sexual system and binomial nomenclature were established, which made botany easier to have access. From 1760s to 1830s, Linnaean botany was fashionable in Europe especially in England. With its feminine characteristics and under the influence of Rousseau, many women engaged in the learning, research and popularization of botany. They wrote a lot of popular botanical books, most of which were in the forms of letters and dialogues. Those women had different background; however, all of them faced difficulties because of their gender.%科学在18世纪的欧洲文化中盛行,其中植物学似乎更具女性气质,在社会看来更适合女性参与。林奈性分类系统和双名制命名法的确立简化了植物学,使植物学更加容易学习。18世纪60年代,林奈植物学流行于欧洲尤其是英国,大量女性参与到植物学的学习、研究和传播中,一直持续到19世纪30年代,植物学开始职业化和男性化。受到卢梭《值物学通干言》的影响,女性作家们以书信和对话体的形式撰写了大量植物学普及读物。女性投身植物学的原因各异,但她们在参与植物学的传播和研究中同样都面临性另4的困境。

  19. Watershed Landscape Ecology: Interdisciplinary and Field-based Learning in the Northeast Creek Watershed, Mount Desert Island, Maine

    Hall, S. R.; Anderson, J.; Rajakaruna, N.; Cass, D.

    2014-12-01

    At the College of the Atlantic, Bar Harbor, Maine, undergraduate students have the opportunity to design their own curriculum within a major of "Human Ecology." To enable students to have early research experiences, we developed a field-based interdisciplinary program for students to learn and practice field methods in a variety of disciplines, Earth Science, Botany, Chemistry, and Wildlife Biology at three specific field sites within a single watershed on Mt. Desert Island. As the Northeast Creek watershed was the site of previous water quality studies, this program of courses enabled continued monitoring of portions of the watershed. The program includes 4 new courses: Critical Zone 1, Critical Zone 2, Wildlife Biology, and Botany. In Critical Zone 1 students are introduced to general topics in Earth Science and learn to use ArcGIS to make basic maps. In Critical Zone 2, Wildlife Biology, and Botany, students are in the field every week using classic field tools and methods. All three of these courses use the same three general field areas: two with working farms at the middle and lower portion of the watershed and one uninhabited forested property in the higher relief headwaters of the watershed. Students collect daily surface water chemistry data at five stream sites within the watershed, complete basic geologic bedrock and geomorphic mapping, conduct wildlife surveys, botanical surveys, and monitor weather patterns at each of the main sites. Beyond the class data collected and synthesized, students also complete group independent study projects at focused field sites, some of which have turned into much larger research projects. This program is an opportunity for students and faculty with varied interests and expertise to work together to study a specific field locality over multiple years. We see this model as enhancing a number of positive education components: field-based learning, teamwork, problem solving, interdisciplinary discussion, multiple faculty

  20. Training centres in Latin America

    Early 1958 the Brazilian representative on the Board of Governors of the International Atomic Energy Agency - supported by the Governors from Argentina and Guatemala -proposed that a study should be made of the possibility of setting up one or more atomic energy training centres in Latin America. On the Board's recommendation, the Director General of the Agency appointed a fact-finding team to make anon-the-spot study. In drafting this report the team was invited to consider the following points: (a) The need for establishing one or more regional training centres; (b) Existing facilities that are being or could be used for training, together with technical data concerning them; (c) The general scientific technological and industrial conditions of the countries visited insofar as they have a bearing on their training needs and capabilities. The authors of the report conclude that 'a training centre in radio-botany should provide vitally needed knowledge and vitally needed specialists to all the agricultural installations in Latin America. A training centre like this might provide an excellent model upon which to base training centres in other areas'. The report recommends that: 1. The Agency should meet the requests of Latin American universities by, for example, supplying equipment and sending experts; 2. At least one specialized training centre should be established as soon as possible. Taking as an example the field of radio-botany, such a centre would provide trained specialists in radio-botany to agricultural institutions throughout Latin America and also provide basic research results vital to agriculture. The cost of new facilities might be of the order of $7 500 000, with an annual budget of approximately $650 000. Staff required: 40 scientists and 175 employees; 3. Whenever it appears feasible to gather necessary staff of high creative ability and established productivity and when funds can be made available for facilities, equipment and operating costs, at
