Higher education biology students’ conceptions on botany teaching : a Brazil – Portugal case study

OpenAIRE

Silva, João Rodrigo Santos da; Guimarães, Fernando; Sano, Paulo Takeo

2012-01-01

Generally, the teaching of botany is seen as mainly based on the transmission of knowledge and on empirical-logical thinking, in a context of scientific knowledge and with the purpose of affirming truth about the world. From this perspective, both in Brazil and in Portugal botany is usually seen as a list of scientific names remote from the daily life of students, which might make classes demotivating. This project was designed with the aim of understanding the prior conceptions of higher ...

Nature in Botany and Zoology in the Spanish Literature: La Celestina

Directory of Open Access Journals (Sweden)

Pardo de Santayana, Manuel

2011-06-01

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.

Locke and botany.

Science.gov (United States)

Anstey, Peter R; Harris, Stephen A

2006-06-01

This paper argues that the English philosopher John Locke, who has normally been thought to have had only an amateurish interest in botany, was far more involved in the botanical science of his day than has previously been known. Through the presentation of new evidence deriving from Locke's own herbarium, his manuscript notes, journal and correspondence, it is established that Locke made a modest contribution to early modern botany. It is shown that Locke had close and ongoing relations with the Bobarts, keepers of the Oxford Botanic Garden, and that Locke distributed seeds and plant parts to other botanists, seeds of which the progeny almost certainly ended up in the most important herbaria of the period. Furthermore, it is claimed that the depth of Locke's interest in and practice of botany has a direct bearing on our understanding of his views on the correct method of natural philosophy and on the interpretation of his well known discussion of the nature of species in Book III of his Essay concerning human understanding.

Mali, Prashant Y; Panchal, Shital S

2017-05-01

The present review is intended to provide information on botany, ethnomedicinal uses, phytochemistry and biological activities of various parts of Euphorbia neriifolia (E. neriifolia). E. neriifolia has several ethnomedicinal uses. The latex of E. neriifolia is used as laxative, purgative, rubefacient, carminative and expectorant as well as in treatment of whooping cough, gonorrhoea, leprosy, asthma, dyspepsia, jaundice, enlargement of the spleen, tumours, stone in the bladder, abdominal troubles and leucoderma. Leaves are brittle, heating, carminative, and good for improving the appetite and treatment of tumours, pains, inflammations, abdominal swellings and bronchial infections. Roots are used as symptomatic treatment of snake bite, scorpion sting and antispasmodic. Various plant parts or whole E. neriifolia extract and its isolates have been reported scientifically using various in-vivo and in-vitro experimental methods for anaesthetic, analgesic, anti-anxiety, anti-convulsant, anti-psychotic, anti-arthritis, anti-carcinogenic, antidiabetic, anti-diarrhoeal, anti-inflammatory, anti-thrombotic, antimicrobial, antioxidant, antiulcer, cytotoxic, death-receptor expression enhancing, dermal irritation, diuretic, haemolytic, immunomodulatory, radioprotective, scorpion venom and wound healing properties. It is reported to have chemical constituents like, neriifolin-S, neriifolin, neriifoliene, euphol, neriifolione, cycloartenol, nerifoliol, lectin, euphonerins A-G, 3-O-acetyl-8-O-tigloylingol, taraxerol, antiquorin, etc. Identified chemical constituents are still required to be explored for their advanced isolation techniques and biological activities.

Maroyi, Alfred

2017-11-01

Euclea undulata (E. undulata) is traditionally used for the treatment of body pains, chest complaints, cough, diabetes, diarrhoea, headaches, heart diseases and toothaches in southern Africa. This study was aimed at reviewing the botany, ethnopharmacology and biological activities of E. undulata in southern Africa. Results presented in this study are based on review of literature using search engines such as Science Direct, Springerlink, Scopus, PubMed, Web of Science, BioMed Central and Google Scholar. Herbal medicine is prepared from the decoctions of the roots, bark and leaves, and extracts of these plant parts have demonstrated anticholinesterase, anti-inflammatory, antimicrobial, antimycobacterial, antiplasmodial, antioxidant and hypoglycaemic activities. Multiple classes of phytochemical compounds such alkaloids, diterpenes, fatty acids, flavonoids, glycosides, naphthoquinones, phenolics, phytosterols, reducing sugars, saponins and tannins have been isolated from the species. E. undulata has a lot of potential as herbal medicine in tropical Africa, and advanced research is required aimed at correlating its medicinal uses with the phytochemistry and pharmacological properties.

Souza, Marcy J; Cox, Sherry K

2011-01-01

Numerous analgesics are available for use in animals, but only a few have been used or studied in zoologic species. Tramadol is a relatively new analgesic that is available in an inexpensive, oral form, and is not controlled. Studies examining the effect of tramadol in zoologic species suggest that significant differences exist in pharmacokinetics parameters as well as analgesic dynamics. This article reviews the current literature on the use of tramadol in humans, domestic animals, and zoologic species. Copyright © 2011 Elsevier Inc. All rights reserved.

[Live Animals and Staged Nature : Drawing and Photography in German Popular Zoology between 1860 and 1910].

Science.gov (United States)

Gall, Alexander

2017-06-01

It is the central thesis of this paper that the "biological perspective" (Lynn Nyhart) typical for Germany, with its interest in living animals, not only influenced natural history practices in many ways during the second half of the 19th century, rather also shaped the illustrations of popular zoology publications, as for example those in Brehms Thierleben. The illustrators of this period preferred to use live animals as models, which they studied in zoos. These animals were often depicted in their "natural" habitats. Since the illustrators knew only very little about these habitats, they had to be imagined. Another fashionable genre within popular zoology was the portrayal of animals fighting, which attracted attention because of their drama. The first wildlife photographers oriented themselves on the zoological illustrations and, with the aid of manipulation, staging and retouching, gave their photographs the impression of natural surroundings and drama. Yet both the illustrators and the photographers emphasized their truth to nature and - based on this - the scientific value of their pictures. In so doing, they developed a "biological" kind of wildlife photography, which, after the turn of the 19th century, allowed dedicated amateurs to create a popular zoological oeuvre that was well received by broad audiences.

[Zoological diagnostics of soils: imperatives, purposes, and place within soil zoology and pedology].

Science.gov (United States)

Mordokovich, V G

2013-01-01

Zoological diagnostics of soils was conceived by M.S. Ghilarov as a part of soil zoology and intended to be closely related to pedology. He considered zoo-agents as an ecological factor, one among many others, of soil formation. Contemporary soil diagnostics pursues mostly utilitarian goals and is based on conservative properties of the stable part of soil substrate. However, it is admitted that these properties are generated by specific combinations of biological, chemical, and physical phenomena that are called "elementary soil processes" (ESP) and occur nowhere but in soils. Certain ESPs are associated with distinctive combinations of biota, including invertebrates. Pedobionts act as producers of detritus and contribute to humus formation, which is necessary for any ESP starting, thus being its active party. That is why animals, being the most complex and active part of the ESP system, may be treated not only as its indicators but also as its navigators. Monitoring and studying of ESPs in soil is complicated because of inevitable disturbance of soil profile natural composition. Zoo-agents, at the same time, can be registered without habitats changing. Taking into account ecological potency of soil invertebrates that participate in an ESP, spectra of their eco-groups, life forms, and results of their activity, it is possible to diagnose a soil state at different stages of certain ESPs development, with their different combinations, and in different regions or parts of natural environmental gradients.

Polypharmacy in Zoological Medicine

Directory of Open Access Journals (Sweden)

Robert P. Hunter

2017-02-01

Full Text Available Polypharmacy is a term that describes the inappropriate, concurrent use of multiple drugs in an individual patient. Zoological medicine practitioners must take approved agents (veterinary or human and extrapolate their use to non-approved species often with little species-specific pharmacological evidence to support their decisions. When considering polypharmacy, even less information exists concerning multi-drug pharmacokinetics, pharmacodynamics, or potential drug-drug interactions in non-domestic species. Unfortunately, captive, zoological species are susceptible, just like their domestic counterparts, to chronic diseases and co-morbidities that may lead to the usage of multiple drugs. Polypharmacy is a recognized and important issue in human medicine, as well as an emerging issue for veterinarians; thus, this paper will discuss the novel, potential risks of polypharmacy in zoological medicine. Hopefully, this discussion will help bring the attention of veterinarians to this issue and serve as an interesting discussion topic for pharmacologists in general.

Botany in Edinburgh's Medical Curriculum.

Science.gov (United States)

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.

One hundred and twenty-five years of the Annals of Botany. Part 2: the years 1937 to 2012.

Annals of Botany is a peer-reviewed plant biology journal. It was started in 1887, making it the oldest continuously published plant science title. A previous article [Jackson MB. 2015. One hundred and twenty-five years of the Annals of Botany Part 1: the first 50 years (1887-1936). Annals of Botany 115: : 1-18] summarized events leading to its founding, highlighted the individuals involved and examined the Journal's achievements and management practices over the first 50 years to 1937. This second article covers the next 75 years. The account draws principally on the Journal's own records, minute books, financial accounts, original letters and notes held by the Annals of Botany Company, the Journal's owners and managers. In 1937, its 51st year, the Journal was re-launched as Annals of Botany New Series and its volume numbers were reset to No. I. The present article evaluates the evolution of the New Series up to 2012, Annals of Botany's 125th anniversary year. The period includes a 2-year run-up to World War II, six war years and their immediate aftermath, and then on through increasingly competitive times. The ebb and flow of the Journal's fortunes are set against a roll-call of the often highly distinguished scientists who managed and edited the Journal. The article also examines an internal crisis in the 1980s that radically altered the Journal's organization in ways that were, ultimately, to its benefit. The narrative is set against changes to economic conditions in Great Britain over the period, to the evolving nature and geographical distribution of much experimental plant science and to the digital revolution that, from the late 20th century, transformed the workings of Annals of Botany and of scientific publishing more generally. © The Author 2016.

The Plymouth Laboratory and the institutionalization of experimental zoology in Britain in the 1920s.

Science.gov (United States)

Erlingsson, Steindór J

2009-01-01

The Plymouth Laboratory of the Marine Biological Association of the United Kingdom (1884) was founded in 1888. In addition to conducting morphological and other biological research, the founders of the laboratory aimed at promoting research in experimental zoology which will be used in this paper as a synonym for e.g. experimental embryology, comparative physiology or general physiology. This dream was not fully realized until 1920. The Great War and its immediate aftermath had a positive impact on the development of the Plymouth Laboratory. The war greatly upset the operation of the Zoological Station in Naples and the ensuing crisis in its operations was closely related to the establishment of the physiological department in Plymouth in 1920. Two other key factors in the Plymouth story were the establishment of the Development Fund in 1909, which began contributing funds to the Plymouth Laboratory in 1912, and the patronage of the Cambridge zoologist George P. Bidder (1863-1954). This paper will focus on the combined influence of the Development Fund and Bidder on the development of the Plymouth Laboratory from around 1902 through the early 1920s, and the important role the laboratory played in promoting experimental zoology in Britain in the 1920s.

2015-01-01

The Annals of Botany is a peer-reviewed scientific journal publishing papers on a wide range of topics in plant biology. It first appeared in 1887, making it the oldest continuously published botanical title. The present article gives a historical account of events leading to the founding of the Journal and of its development over the first 50 years. Much of the content is drawn from the Journal's own records and from extensive Minutes, financial accounts, personal letters and notes relating to the Annals of Botany that were repatriated from University College, University of London in 1999. Documents held at the Royal Botanic Gardens, Kew and at the Oxford University Press Museum were also consulted. Emphasis is placed on the individuals who instigated, edited and managed the Annals of Botany up to 1937, especially the nine founding members of the Journal and the background that brought them together and motivated them to start the Annals of Botany. A falling out between two of the founders in 1899 is highlighted since not only did this threaten the Journal's future but also gives much insight into the personalities of those most closely involved in the Journal during its formative years. The article also examines the way the Journal was funded and how it dealt with its publisher (the University of Oxford's Clarendon Press), turned itself into a registered company (the Annals of Botany Company) and coped with the travails of the First World War, currency inflation and the Great Depression. Plans to re-start the Journal as a New Series, beginning in 1937, are discussed in the context of the competition the Annals of Botany then faced from younger journals. © The Author 2014.

Plans to re-start the Journal as a New Series, beginning in 1937, are discussed in the context of the competition the Annals of Botany then faced from younger journals. PMID:25561090

Amplified fragment length polymorphism (AFLP) is a new molecular marker to detect genomic polymorphism. This new technology has advantages of high resolution, good stability, and reproducibility. Great achievements have been derived in recent years in AFLP related technologies with several AFLP expanded methodologies available. AFLP technology has been widely used in the fields of plant, animal, and microbes. It has become one of the hotspots in Forensic Botany. This review focuses on the recent advances of AFLP and its applications in forensic biology.

The voice of American botanists: the founding and establishment of the American Journal of Botany, "American botany," and the Great War (1906-1935).

Science.gov (United States)

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.

Little Botany: A Mobile Game Utilizing Data Integration to Enhance Plant Science Education

Directory of Open Access Journals (Sweden)

Suphanut Jamonnak

2017-01-01

Full Text Available Mobile devices are rapidly becoming the new medium of educational and social life for young people, and hence mobile educational games have become an important mechanism for learning. To help school-aged children learn about the fascinating world of plants, we present a mobile educational game called Little Botany, where players can create their own virtual gardens in any location on earth. One unique feature of Little Botany is that the game is built upon real-world data by leveraging data integration mechanism. The gardens created in Little Botany are augmented with real-world location data and real-time weather data. More specifically, Little Botany is using real-time weather data for the garden location to simulate how the weather affects plants growth. Little Botany players can learn to select what crops to plant, maintain their own garden, watch crops to grow, tend the crops on a daily basis, and harvest them. With this game, users can also learn plant structure and three chemical reactions.

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

Hospice in a zoologic medicine setting.

Science.gov (United States)

Jessup, David A; Scott, Cheryl A

2011-06-01

Forty years ago, Dr. Elizabeth Kubler-Ross in her landmark book On death and dying observed "maybe at the end of our days, when we have worked and given, enjoyed ourselves and suffered, we are going back to the stage that we started out with and the circle of life is closed." Just as human life expectancy has steadily increased over the last 4 or 5 decades, animal life expectancy has increased, including that of zoologic species. With this has come a need for humans to openly and frankly deal with end-of-life issues for themselves and for their animals, including those in zoos. By necessity, zoos have been dealing with problems such as aggressive pain management and triage, and efforts to incorporate end-of-life care into zoologic medicine. But these efforts have yet to include formal acknowledgment that they are a basic form of hospice. Hospice for humans, and now for companion animals, includes much more than pain relief and geriatric care. This article reviews the concepts and basic practices of hospice and the closely related field of palliative care, their relatively recent application to companion animal care, potential applications to zoologic medicine, and the ways this could provide opportunities for personal growth of zoo visitors and staff, including veterinary staff.

Proposal to modify Rule 10a and to delete Recommendation 10a(3) from the International Code of Nomenclature of Prokaryotes.

Science.gov (United States)

Oren, Aharon

2017-09-01

Principle 2 of the Prokaryotic Code, as modified by the ICSP in 1999, reads: 'The nomenclature of prokaryotes is not independent of botanical and zoological nomenclature. When naming new taxa in the rank of genus or higher, due consideration is to be given to avoiding names which are regulated by the International Code of Zoological Nomenclature and the International Code of Nomenclature for algae, fungi and plants'. But in the current version of the Prokaryotic Code no Rule implements this version of Principle 2. I therefore propose adding the following sentence to Rule 10a: 'As from January 2001, newly proposed generic names must not be later homonyms of names in use in botany or zoology'. Recommendation 10a(3) of the Code states: 'Avoid introducing into bacteriology as generic names such names as are in use in botany or zoology, in particular well-known names'. This Recommendation contravenes the current version of Principle 2 and the proposed new version of Rule 10a. Therefore I propose to delete Recommendation 10a(3) from the Prokaryotic Code.

Radix Bupleuri: A Review of Traditional Uses, Botany, Phytochemistry, Pharmacology, and Toxicology.

Science.gov (United States)

Yang, Fude; Dong, Xiaoxv; Yin, Xingbin; Wang, Wenping; You, Longtai; Ni, Jian

2017-01-01

Radix Bupleuri (Chaihu) has been used as a traditional medicine for more than 2000 years in China, Japan, Korea, and other Asian countries. Phytochemical studies demonstrated that this plant contains essential oils, triterpenoid saponins, polyacetylenes, flavonoids, lignans, fatty acids, and sterols. Crude extracts and pure compounds isolated from Radix Bupleuri exhibited various biological activities, such as anti-inflammatory, anticancer, antipyretic, antimicrobial, antiviral, hepatoprotective, neuroprotective, and immunomodulatory effects. However, Radix Bupleuri could also lead to hepatotoxicity, particularly in high doses and with long-term use. Pharmacokinetic studies have demonstrated that the major bioactive compounds (saikosaponins a, b 2 , c, and d) were absorbed rapidly in rats after oral administration of the extract of Radix Bupleuri . This review aims to comprehensively summarize the traditional uses, botany, phytochemistry, pharmacology, toxicology, and pharmacokinetics of Radix Bupleuri reported to date with an emphasis on its biological properties and mechanisms of action.

Changing techniques in crop plant classification: molecularization at the National Institute of Agricultural Botany during the 1980s.

Science.gov (United States)

Holmes, Matthew

2017-04-01

Modern methods of analysing biological materials, including protein and DNA sequencing, are increasingly the objects of historical study. Yet twentieth-century taxonomic techniques have been overlooked in one of their most important contexts: agricultural botany. This paper addresses this omission by harnessing unexamined archival material from the National Institute of Agricultural Botany (NIAB), a British plant science organization. During the 1980s the NIAB carried out three overlapping research programmes in crop identification and analysis: electrophoresis, near infrared spectroscopy (NIRS) and machine vision systems. For each of these three programmes, contemporary economic, statutory and scientific factors behind their uptake by the NIAB are discussed. This approach reveals significant links between taxonomic practice at the NIAB and historical questions around agricultural research, intellectual property and scientific values. Such links are of further importance given that the techniques developed by researchers at the NIAB during the 1980s remain part of crop classification guidelines issued by international bodies today.

[Lysenkoism in Polish botany].

Science.gov (United States)

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

Full Text Available Purpose: The objective of this research is to determine the service improvement priority based on tourist judgements and experiences on service quality in a zoological park. Design/methodology/approach: A powerful integrated model was developed to acquire accurate critical service attributes and their priority ranks that can promote tourist satisfaction and tourist loyalty. Drawing on relevant literature, a model was proposed based on tourists’ perspective by integrating structural equation model (SEM with SERVQUAL and refined Kano models. Findings and Originality/value: Based on the analysis of data through some quantitative tools, the study helped in prioritizing the critical service attributes, which, if adopted, improved, and implemented, could lead to satisfaction of tourists. This will help a zoological park to propose more efficient and value-added improvement policies of the service Research limitations/implications: The primary limitation in the scope its sample. Because the study involved only one Zoological Park in Indonesia, the results cannot be generalized across a national wide spectrum. Originality/value: The study was the first to successfully apply an integrated model in tourism sector, which has previously not been used. The study has hopefully opened up an area of research and methodology that could provide considerable further benefits for researchers interested in this topic. Moreover, the integrated model has proven to be useful in determining the priority rank of critical service quality attributes.

A new era in science at Washington University, St. Louis: Viktor Hamburger's zoology department in the 1940's.

Science.gov (United States)

Carson, H L

2001-04-01

In the early 1940s, the administration of the College of Arts and Sciences at Washington University, St. Louis was firmly in the hands of classical scholars who were not inclined to promote the development of modern research on scientific subjects. Funds supporting research in biology favored the School of Medicine and the Missouri Botanical Garden. Viktor Hamburger arrived at Washington University in 1935. At about the time he became the Acting Chairman of Zoology in 1942, research work in the biological departments began a dramatic surge that has continued to this day. For 65 years under his counsel and leadership, basic biology has thrived at this fine institution. As an early faculty recruit, I recount here a few personal recollections from those formative years.

Elements of plant physiology in theophrastus' botany.

Science.gov (United States)

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.

Which Wild Aardvarks Are Most Suitable for Outdoor Enclosures in Zoological Gardens in the European Union?

Science.gov (United States)

Patoka, Jiří; Vejtrubová, Markéta; Vrabec, Vladimír; Masopustová, Renata

2018-01-01

The aardvark is popular in many zoological gardens in the European Union. These creatures are nocturnal, and aardvarks in the wild are known to walk distances of 4 km to 7 km per night. Despite what is known about their biology, most aardvarks are kept in zoological gardens in indoor enclosures with little space for movement. This lack of space leads to a tendency toward obesity and compromised welfare. With their wide distribution in Sub-Saharan Africa, aardvarks are perceived as thermophilic nonhuman animals. Nevertheless, some records suggest they may be able to adapt to colder climates and can be active outside their burrows when temperatures fall to 2°C. These findings suggest there may be a wild African population that is suitable for partial outdoor keeping under European climatic conditions. Therefore, a climate match was computed between the source area with aardvark occurrence and a target area of the European Union. Data revealed that the Free State, a South African province, was the area with the best climate similarity, and aardvarks from this area are recommended as suitable for the aforementioned purpose.

Afrikaans in Botany after 75 years of “Akademie” activities

Directory of Open Access Journals (Sweden)

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.

Comparative study of the introduction of modern botany in Japan and China.

Science.gov (United States)

Métailié, Georges

2002-03-01

Prior to the eighteenth-century, a similar approach towards the vegetable kingdom, mainly influenced by the tradition of the Chinese pharmacopoeias, could be observed in China and Japan. During the eighteenth-century, the interest for "Dutch learning" led some Japanese physicians and interpreters to be more and more interested in Western knowledge about medicinal plants. At the beginning of the nineteenth-century, a few scholars, through direct contact with foreigners or with foreign books, realised that there was a specific scientific field called "botany" and began to introduce the Japanese scholarly community to this new science which became one of the subjects taught at the "University of Tokyo" in 1877. In China, up to the middle of the nineteenth-century, no trace of modern botany can be found in any published document. In the second half of the century, a few botanical treatises were published, all being adaptations or translations of Western books, done by foreign-Chinese teams of translators. This situation began to change when Chinese students had the opportunity to go and study abroad, mainly to Japan, at the beginning of the twentieth-century, and, actually, it is between 20 and 30 years later that botany became a real scientific practice in China. We will analyse these two processes, their specificities and their interactions.

Critical factors for sustainable food procurement in zoological collections.

Science.gov (United States)

Hanson, Jonathan H

2015-01-01

Food procurement can play an important role in sustainable food supply chain management by zoos, linking organizational operations to the biodiversity conservation and sustainability mission of zoological collections. This study therefore examines the critical factors that shape sustainable food procurement in zoo and aquariums. Using a web-based survey data was collected from 41 members of the British and Irish Association of Zoos and Aquariums (BIAZA). This included information on the sustainable food procurement practices of these institutions for both their human and animal food supply chains, as well as profile information and data on the factors contributing to and inhibiting sustainable procurement practices. Zoological collections operated by charities, and those with a certified sustainability standard, were found to have significantly higher levels of sustainable food procurement. Zoos and aquariums whose human food operations were not contracted to an external party were also found to have significantly higher levels of sustainable food procurement in their human food supply chain. The most important drivers of sustainable food procurement were cost savings, adequate financial support and improved product quality. The highest ranking barriers were higher costs, other issues taking priority and a lack of alternative suppliers. The results suggest that a number of critical factors shape sustainable food procurement in zoological collections in the British Isles. Financial factors, such as cost savings, were important considerations. The significance of mission-related factors, such as charity status, indicated that core values held by zoos and aquariums can also influence their food procurement practices. © 2015 Wiley Periodicals, Inc.

Melding Research and Education in a Zoological Setting

Science.gov (United States)

Foote, Dustin

The first zoo was opened in London in 1828 and was intended for scientific study, but was eventually opened to the public in 1847. Since then, public dogma has dictated the development, role, and standards concerning the use of animals across the zoological community. Too often there is disconnect between research programs, captive propagation, and public education. In the fight against human driven extinction of earth's flora and fauna, it is vital that these areas be aligned. Thus in an effort to unite research and education in a zoological setting, East Carolina University (ECU) and Sylvan Heights Bird Park (SHBP) have partnered for a collaborative project involving the study of evolution in the African brood parasitic finches (Viduidae), specifically he Pin-tailed Whydah (Vidua macroura). I attempt to quantify the educational impact of Avian Pirates and SHBP, and assess basic demographic factors that will allow insights into what areas of exhibit design pertain to education. It is important to understand what aspects of zoos facilitate visitor learning in areas of conservation and biodiversity. This is vital as Zoos are under new pressure to substantiate claims of education during visits.

Movement to curtail animal dissections in zoology curriculum: review of the Indian experience.

Science.gov (United States)

Akbarsha, Mohammad Abdulkader

2007-01-01

Animal dissections have been dropped from the curriculum in several developed countries, and virtual laboratories are taking their place, or at least the concept of the "three R's" is becoming accepted. Yet, the scenario in the developing countries in this regard has been dismal. However, recently, a movement has started in India in this area, thanks to the aggressive approach of PfA, I-CARE and InterNICHE, supported by a few zoology educators and policy makers, who joined this movement as freelancers. The aggressive campaigners against animal dissections put up convincing arguments to the orthodox zoology educators and higher education planners with such veracity that the arguments cannot be ignored. The arguments, to be presented in detail at the conference, and the campaign have been rewarded with success such that a few universities and autonomous colleges have revamped their zoology curricula so as to dispense with or reduce animal dissections. The Bharathidasan University, Tiruchirappalli, Tamil Nadu, India, has been the trendsetter, evolving what is known as the "Bharathidasan University Model". A memorandum from I-CARE and PfA to the University Grants Commission, Government of India, New Delhi, was sent out by the UGC to the universities with a request to consider the points positively. However, there is still a need to bring about an attitudinal change in the zoology educators and higher education planners such that they participate willingly in this endeavour. The role-players at all levels are identified and approached with a language that is understandable to each and are adequately supported by hands-on training in the alternative methods. Ultimately, the responsibility in this regard lies with the educators themselves, since they are the ones who, working in the academic committees that design the curricula, can cut down on the requirement for dissections.

Learning in human-dolphin interactions at zoological facilities

Science.gov (United States)

Sweeney, Diane L.

This research aimed to better understand learning in zoological settings, particularly learning about marine mammals, by investigating the research question, what do people learn through interacting with dolphins in zoological facilities? Sociocultural situated learning theory, specifically a Community of Practice (CoP) model of learning (Lave & Wenger, 1991), was the theoretical framework. The CoP model allowed for diversity of knowledge, interest, motivations, and goals that existed among the community of animal enthusiasts at three commercial zoological facilities, and also for peripheral to more central types of participation. I collected data through interviews of spectators, visitors, and trainers (n=51), observations (n=16), and an online questionnaire of past-visitors (n=933). Data were coded, categorized, and analyzed based on the National Science Foundation's (Friedman, 2008) and the National Research Council's (2009) frameworks for informal science education. Five principal findings answered the research question. First, all participants gained new knowledge within three broad categories: (a) dolphin physiology and natural history, (b) care and training of dolphins, and (c) conservation. Second, all participants constructed personal meanings by connecting the activity to experiences, beliefs, and practices outside the interaction context. Almost all participants made associations with conservation. Third, most participants shifted their attitudes and gained a sense of personal agency about beginning or increasing stewardship actions. Fourth, visitors learned interspecies etiquette skills; trainers learned skills in dolphin training and management, people management, and teaching. Fifth, visitors had long-lasting memories of the experience that occurred eight months to 18 years in the past. Popular cultural ideas about dolphins and the ways the dolphins were represented influenced visitors' expectations and the types of learning. Potential physical

Controlling and culturing diversity: experimental zoology before World War II and Vienna's Biologische Versuchsanstalt.

Logan, Cheryl A; Brauckmann, Sabine

2015-04-01

Founded in Vienna in 1903, the Institute for Experimental Biology pioneered the application of experimental methods to living organisms maintained for sustained periods in captivity. Its Director, the zoologist Hans Przibram, oversaw until 1938, the attempt to integrate ontogeny with studies of inheritance using precise and controlled measurements of the impact of environmental influences on the emergence of form and function. In the early years, these efforts paralleled and even fostered the emergence of experimental biology in America. But fate intervened. Though the Institute served an international community, most of its resident scientists and staff were of Jewish ancestry. Well before the Nazis entered Austria in 1938, these men and women were being fired and driven out; some, including Przibram, were eventually killed. We describe the unprecedented facilities built and the topics addressed by the several departments that made up this Institute, stressing those most relevant to the establishment and success of the Journal of Experimental Zoology, which was founded just a year later. The Institute's diaspora left an important legacy in North America, perhaps best embodied by the career of the developmental neuroscientist Paul Weiss. © 2015 Wiley Periodicals, Inc.

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

Science.gov (United States)

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.

Simaroubaceae family: botany, chemical composition and biological activities

Directory of Open Access Journals (Sweden)

Iasmine A.B.S. Alves

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.

Strychnos nux-vomica L. belongs to the genus Strychnos of the family Loganiaceae and grows in Sri Lanka, India and Australia. The traditional medicinal component is its seed, called Nux vomica. This study provides a relevant and comprehensive review of S. nux-vomica L., including its botany, ethnopharmacology, phytochemistry, pharmacology and toxicology, thus providing a foundation for future studies. Up to the present day, over 84 compounds, including alkaloids, iridoid glycosides, flavonoid glycosides, triterpenoids, steroids and organic acids, among others, have been isolated and identified from S. nux-vomica. These compounds possess an array of biological activities, including effects on the nervous system, analgesic and anti-inflammatory actions, antitumor effects, inhibition of the growth of pathogenic microorganisms and regulation of immune function. Furthermore, toxicity and detoxification methods are preliminarily discussed toward the end of this review. In further research on S. nux-vomica, bioactivity-guided isolation strategies should be emphasized. Its antitumor effects should be investigated further and in vivo animal experiments should be performed alongside in vitro testing. The pharmacological activity and toxicology of strychnine [Formula: see text]-oxide and brucine [Formula: see text]-oxide should be studied to explore the detoxification mechanism associated with processing more deeply.

Conflict or convergence ? Perceptions of teachers and students about ethics in the use of animals in Zoology teaching

Directory of Open Access Journals (Sweden)

Kênio E. C. Lima

2008-12-01

Full Text Available The use of animals in practical classes in university courses requires a bioethical approach so that zoological concepts are constructed along humanistic criteria. This is particularly relevant in Science teaching courses, since the approach will reflect in the graduates will teach in elementary levels. This work aimed to investigate the conceptions of teachers and undergraduate students from courses of Biological Sciences about the use of animals in didactic situations. Questionnaires were applied to students and teachers, regarding topics such as collection and killing of animals, alternative resources and guidelines for bioethical procedure. We noticed convergence and conflict among the perceptions and attitudes from teachers and students. Some of them agree with the replacement of animals for alternative resources, although orientations about the legal framework related to the topic are neglected. We propose an in-depth discussion about a multidisciplinary insertion of animal bioethics in the education of Biology teachers

2014-01-01

Full Text Available Visitors have various motives for visiting a zoo. Information on these motives can be applied by zoo management to make informed decisions when developing a marketing strategy to ensure the success and future relevance of the zoo. This study has aimed to determine whether visitors are motivated to visit the National Zoological Gardens of South Africa for recreational or educational purposes, and whether their motives are geared towards their own benefit (intrinsic motives or to the benefit of others (altruistic motives. The research was conducted by means of a quantitative survey. The results indicate that the respondents view recreational motives as more important than educational motives. In addition, more people visit the zoo to promote the welfare of others (altruistic orientation than to have a self-directed zoo experience (intrinsic orientation. The findings suggest that the management of the zoological parks should ensure that the parks offer activities and experiences of recreational value for visitors. These activities should be communicated to the relevant target markets, in order to attract them to the zoo, which could contribute to the long-term survival and success of the zoo.

Tropical veterinary parasites at Harvard University's Museum of Comparative Zoology.

Science.gov (United States)

Conn, David Bruce

2008-12-01

Tropical veterinary parasites have been maintained by the Museum of Comparative Zoology (MCZ) at Harvard University since the mid 1800s. Most of these are maintained by the Department of Invertebrate Zoology, but many vectors and intermediate hosts are maintained by the Departments of Entomology and Malacology. The largest collections are of avian and mammalian ticks (Acarina) that are important as both parasites and vectors. Nematodes are second in numbers, followed by cestodes, trematodes, and several minor helminth groups, crustacean parasites of fish, and protozoan parasites of various hosts. The MCZ directed or participated in several major expeditions to tropical areas around the globe in the early 1900s. Many of these expeditions focused on human parasites, but hundreds of veterinary and zoonotic parasites were also collected from these and numerous, smaller, tropical expeditions. Host sources include companion animals, livestock, laboratory species, domestic fowl, reptiles, amphibians, exotics/zoo animals, commercially important fishes, and other wildlife. Specimens are curated, either fixed whole in vials or mounted on slides as whole mounts or histopathological sections. The primary emphasis of MCZ's current work with tropical veterinary parasites is on voucher specimens from epidemiological, experimental, and clinical research.

The List of Available Names (LAN): A new generation for stable taxonomic names in zoology?

Science.gov (United States)

Alonso-Zarazaga, Miguel A; Fautin, Daphne Gail; Michel, Ellinor

2016-01-01

The List of Available Names in Zoology (LAN) is an inventory of names with specific scope in time and content, presented and approved in parts, and constituted as a cumulative index of names available for use in zoological nomenclature. It was defined in Article 79 in the fourth edition of the International Code of Zoological Nomenclature. The LAN is likely to gain importance with the development of the online Official Registry for Zoological Nomenclature (ZooBank) as it is potentially a source of many nomenclaturally certified names. Article 79 describes the deliberative process for adding large numbers of names to the LAN simultaneously, detailing steps and chronology for submission of a candidate Part to the LAN and consideration of a candidate Part by the public and Commission, but it is largely mute about the contents of a candidate Part. It does make clear that a name within the scope of a Part but not on the LAN has no nomenclatural standing, even if it had previously been considered available, thereby preventing long-forgotten names from displacing accepted ones and the accumulation of nomina dubia. Thus, for taxa on the LAN, nomenclatural archaeology - the resurrecting of old unused names to replace by priority names in current usage - will not be worthwhile. Beyond that, it has been unclear if Article 79 is intended to document every available name known within the scope of the Part, or if its intention is to pare the inventory of available names within the scope of the Part. Consideration by the Commission and two committees to deal with the LAN have defined steps to implement Article 79 with the latter intent. Procedures for consideration of a candidate Part are defined in a manual, published as an appendix in this volume.

Publication data relating to a rare and obscure Japanese journal "Lansania Journal of Arachnology and Zoology" (1929-1941) are examined. Available facts, together with a substantial body of circumstantial and anecdotal evidence suggest that many planned issues, including several cited by independent sources as having been published, were not published. Some biographical data relating to the editor, Kyukichi Kishida (1888-1968), are provided. Titles of all papers known to have been published in "Lansania," with page numbers and claimed publication dates are presented, together with a list of 113 new zoological names proposed in the journal. Known library holdings of the journal worldwide are indicated. Details are provided of unpublished manuscripts in proof obtained from Kishida in the 1960s. The strong probability that some printed publication dates are inaccurate is discussed in detail.

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. © The Author 2015.

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. © 2014 American Academy of Forensic Sciences.

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

Science.gov (United States)

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.

Antimicrobial resistance (AMR) in a wide range of infectious agents is a growing public health threat. Birds of prey are considered indicators of the presence of AMR bacteria in their ecosystem because of their predatory behaviour. Only few data are reported in the literature on AMR strains isolated from animals housed in zoos and none about AMR in raptors housed in zoological gardens. This study investigated the antibiotic sensitivity profile of the isolates obtained from the conjunctival and cloacal bacterial flora of 14 healthy birds of prey, 6 Accipitriformes , 3 Falconiformes and 5 Strigiformes , housed in an Italian zoological garden. Staphylococcus spp. was isolated from 50% of the conjunctival swabs, with S. xylosus as the most common species. From cloacal swabs, Escherichia coli was cultured from all animals, while Klebsiella spp. and Proteus spp. were isolated from a smaller number of birds. Worthy of note is the isolation of Escherichia fergusonii and Serratia odorifera , rarely isolated from raptors. Staphylococci were also isolated. All the isolates were multidrug resistant (MDR). To the author's knowledge, this is the first report regarding the presence of MDR strains within raptors housed in a zoological garden. Since resistance genes can be transferred to other pathogenic bacteria, this represents a potential hazard for the emergence of new MDR pathogens. In conclusion, the obtained data could be useful for ex-situ conservation programmes aimed to preserve the health of the endangered species housed in a zoo.

Abstract : There are certain saprophytic fungi in the soil able to develop an antagonistic effect against eggs of parasites. Some of these fungal species are ingested by animals during grazing, and survive in their feces after passing through the digestive tract. To identify and isolate ovicidal fungi in the feces of wild captive animals, a total of 60 fecal samples were taken from different wild animals kept captive in the Marcelle Natureza Zoological Park (Lugo, Spain). After the serial culture of the feces onto Petri dishes with different media, their parasicitide activity was assayed against eggs of trematodes ( Calicophoron daubneyi ) and ascarids ( Parascaris equorum ). Seven fungal genera were identified in the feces. Isolates from Fusarium , Lecanicillium , Mucor , Trichoderma , and Verticillium showed an ovicidal effect classified as type 3, because of their ability to adhere to the eggshell, penetrate, and damage permanently the inner embryo. Penicillium and Gliocladium developed a type 1 effect (hyphae attach to the eggshell but morphological damage was not provoked). These results provide very interesting and useful information about fungi susceptible for being used in biological control procedures against parasites.

Full Text Available Two confirmed cases of fatal disseminated toxoplasmosis occurred in an urban zoological collection of meerkats (Suricata suricatta. Both cases are suspected to be the result of feral cats gaining access to the enclosure. Toxoplasmosis has rarely been documented in meerkats. Subsequent to prophylactic treatment of all the animals and structural changes being implemented within the enclosure, no new cases have been recorded to date. Very little information is available on the disease in viverrids.

The return of the phoenix: the 1963 International Congress of Zoology and American zoologists in the twentieth century.

Science.gov (United States)

Johnson, Kristin

2009-01-01

This paper examines the International Congress of Zoology held in Washington D.C. in 1963 as a portrait of American zoologists' search for effective and rewarding relationships with both each other and the public. Organizers of the congress envisioned the congress as a last ditch effort to unify the disparate subdisciplines of zoology, overcome the barriers of specialization, and ward off the heady claims of more reductionist biologists. The problems zoologists faced as they worked to fulfill these ambitious goals illuminate some of the challenges faced by members of the naturalist tradition as they worked to establish disciplinary unity while seeking public support in the competitive world of twentieth century science.

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.

Authoritative Images. The Kiwi and the Transactions of the Zoological Society of London.

Science.gov (United States)

Canadelli, Elena

2015-01-01

The first exemplar of a kiwi, the wingless bird of New Zealand, arrived in the form of a lifeless specimen in Europe in 1812. A debate was sparked over the appearance and nature of this strange creature and indeed whether it actually existed. In 1833 the Transactions of the Zoological Society of London entered the debate and the illustrations published in this journal contributed greatly to the acceptance and further study of the kiwi. Some of the most eminent British zoologists and anatomists of the time were involved, from William Yarrell to Richard Owen, and from John Gould to Abraham Dee Bartlett. This crucial period in the discussion, which would extend over two decades and would only be brought to a close with the arrival of the first living specimen in the London Zoological Garden in 1851, will be analyzed based on a detailed examination of the reports published in the Transactions and other journals. This essay will show how images of the bird were produced and used by zoologists during different stages in the early research on the bird and how these figures circulated inside and outside the zoologists' community.

2017-09-01

Full Text Available Fecal samples from 24 animals of eight different species were collected at Hann Zoological Park in Senegal. They were analyzed with the Telemann-Rivas qualitative microscopic method and Mac Master quantitative method. Of all the samples, 66.7% were positive, and each positive animal was infested with at least one helminth egg species, whereas protozoa were present in only four animals. In carnivores, the eggs of parasites such as Toxascaris leonina and Toxocara cati, and hookworm eggs were the most present, whereas in primates, the eggs of Trichuris sp. and Entamoeba sp. have been identified. This study provides a basis for the establishment of treat­ments in these animals.

From experimental zoology to big data: Observation and integration in the study of animal development.

Science.gov (United States)

Bolker, Jessica; Brauckmann, Sabine

2015-06-01

The founding of the Journal of Experimental Zoology in 1904 was inspired by a widespread turn toward experimental biology in the 19th century. The founding editors sought to promote experimental, laboratory-based approaches, particularly in developmental biology. This agenda raised key practical and epistemological questions about how and where to study development: Does the environment matter? How do we know that a cell or embryo isolated to facilitate observation reveals normal developmental processes? How can we integrate descriptive and experimental data? R.G. Harrison, the journal's first editor, grappled with these questions in justifying his use of cell culture to study neural patterning. Others confronted them in different contexts: for example, F.B. Sumner insisted on the primacy of fieldwork in his studies on adaptation, but also performed breeding experiments using wild-collected animals. The work of Harrison, Sumner, and other early contributors exemplified both the power of new techniques, and the meticulous explanation of practice and epistemology that was marshaled to promote experimental approaches. A century later, experimentation is widely viewed as the standard way to study development; yet at the same time, cutting-edge "big data" projects are essentially descriptive, closer to natural history than to the approaches championed by Harrison et al. Thus, the original questions about how and where we can best learn about development are still with us. Examining their history can inform current efforts to incorporate data from experiment and description, lab and field, and a broad range of organisms and disciplines, into an integrated understanding of animal development. © 2015 Wiley Periodicals, Inc.

A Space of One's Own: Barbosa du Bocage, the Foundation of the National Museum of Lisbon, and the Construction of a Career in Zoology (1851-1907).

Science.gov (United States)

Gamito-Marques, Daniel

2017-07-18

This paper discusses the life and scientific work of José Vicente Barbosa du Bocage (1823-1907), a nineteenth-century Portuguese naturalist who carved a new place for zoological research in Portugal and built up a prestigious scientific career by securing appropriate physical and institutional spaces to the discipline. Although he was appointed professor of zoology at the Lisbon Polytechnic School, an institution mainly devoted to the preparatory training of military officers and engineers, he succeeded in creating the conditions that allowed him to develop consistent research in zoology at this institution. Taking advantage of the reconstruction and further improvement of the building of the Lisbon Polytechnic, following a violent fire in 1843, Bocage transferred a natural history museum formerly located at the Academy of Sciences of Lisbon to his institution, where he conquered a more prestigious place for zoology. Although successive governments were unwilling to meet Bocage's ambitions for the Zoological Section of the newly created National Museum of Lisbon, the collaborators he found in different parts of the Portuguese continental territory and colonial empire supplied him the specimens he needed to make a career as a naturalist. Bocage ultimately became a renowned specialist in Southwestern African fauna thanks to José de Anchieta, his finest collaborator. Travels to foreign museums, and the establishment of links with the international community of zoologists, proved fundamental to build up Bocage's national and international scientific reputation, as it will be exemplified by the discussion of his discovery of Hyalonema, a specimen with a controversial identity collected off the Portuguese coast.

Volkmann, Dieter; Baluška, František; Menzel, Diedrik

2012-10-01

Eduard Strasburger, director of the Botany Institute and the Botanical Garden at the University of Bonn from 1881 to 1912, was one of the most admirable scientists in the field of plant biology, not just as the founder of modern plant cell biology but in addition as an excellent teacher who strongly believed in "education through science." He contributed to plant cell biology by discovering the discrete stages of karyokinesis and cytokinesis in algae and higher plants, describing cytoplasmic streaming in different systems, and reporting on the growth of the pollen tube into the embryo sac and guidance of the tube by synergides. Strasburger raised many problems which are hot spots in recent plant cell biology, e.g., structure and function of the plasmodesmata in relation to phloem loading (Strasburger cells) and signaling, mechanisms of cell plate formation, vesicle trafficking as a basis for most important developmental processes, and signaling related to fertilization.

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.

Rheum australe D. Don (Polygonaceae) has been commonly used in traditional medicine for a wide range of ailments related to the circulatory, digestive, endocrine, respiratory and skeletal systems as well as to infectious diseases. To provide the up-to-date information that is available on the botany, traditional uses, phytochemistry, pharmacology and toxicology of Rheum australe. Additionally, to highlight the possible uses of this species to treat different diseases and to provide a basis for future research. The present review covers the literature available from 1980 to 2011. The information was collected from scientific journals, books, theses and reports via a library and electronic search (Google Scholar, Web of Science and ScienceDirect). Ethnomedical uses of Rheum australe have been recorded from China, India, Nepal and Pakistan for 57 different types of ailments. The phytochemical studies have shown the presence of many secondary metabolites belonging to anthraquinones, stilbenes, anthrones, oxantrone ethers and esters, chromones, flavonoids, carbohydrate, lignans, phenols and sterols. Crude extracts and isolated compounds from Rheum australe show a wide spectrum of pharmacological activities, such as antidiabetic, anti-inflammatory, antifungal, antimicrobial, antioxidant, anticancer, hepatoprotective and immune-enhancing activities, as well as a usefulness for improving renal function. Rheum australe has been widely used source of medicine for years without any adverse effects. Many studies have provided evidence for various traditional uses. However, there is a need for additional studies of the isolated compounds to validate the traditional uses in human models. The present review on the botany, traditional uses, phytochemistry and toxicity has provided preliminary information for further studies and commercial exploitations of the plant.

Upon the restoration of the Society of Jesus in Portugal in 1858, the Jesuits founded two important colleges that made significant efforts in the promotion of hands-on experimental teaching of the natural sciences. At the Colégio de Campolide (Lisbon, 1858-1910) and the Colégio de São Fiel (Louriçal do Campo, 1863-1910) the Jesuits created modern chemistry and physics laboratories, organized significant botanical, zoological and geological collections, promoted scientific expeditions with their students to observe eclipses and to collect novel species of animals and plants, and engaged in original research work in physics, botany, and zoology. The successful implementation of modern scientific practices gained these colleges public recognition as the most prominent secondary institutions in nineteenth-century Portugal, and this made a major contribution to countering the widespread and commonly accepted anti-Jesuit accusations of obscurantism and scientific backwardness.

Malthus and the Philanthropists, 1764–1859: The Cultural Circulation of Political Economy, Botany, and Natural Knowledge

Directory of Open Access Journals (Sweden)

J. Marc MacDonald

2017-01-01

Full Text Available Modernity does not possess a monopoly on mass incarceration, population fears, forced migration, famine, or climatic change. Indeed, contemporary and early modern concerns over these matters have extended interests in Thomas Malthus. Yet, despite extensive research on population issues, little work explicates the genesis of population knowledge production or how the process of intellectual transfer occurred during the eighteenth and early nineteenth centuries. This paper examines the Delessert network’s instrumental role in cultivating, curating, and circulating knowledge that popularized Malthusian population theory, including the theory’s constitutive elements of political economy, philanthropy, industry, agriculture, and botany. I show how deviant, nonconformist groups suffered forced migration for their political philosophy, particularly during the revolutionary 1790s, resulting in their imprisonment and migration to America. A consequence of these social shifts was the diffusion and dissemination of population theory—as a pursuit of scientific knowledge and exploration—across both sides of the Atlantic. By focusing on the Delesserts and their social network, I find that a byproduct of inter and intra continental migration among European elites was a knowledge exchange that stimulated Malthus’s thesis on population and Genevan Augustin Pyramus Candolle’s research on botany, ultimately culminating in Charles Darwin’s theory of natural selection and human evolution.

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.

Miller Coyle, Heather; Lee, Cheng-Lung; Lin, Wen-Yu; Lee, Henry C; Palmbach, Timothy M

2005-08-01

Forensic botany is still an under-utilized resource in forensic casework, although it has been used on occasion. It is an area of specialty science that could include traditional botanical classification of species, DNA, or materials evidence (trace and transfer evidence), crime mapping or geo-sourcing, all dependent on the specific case application under consideration. Critical to the evaluation of plant evidence is careful collection, documentation, and preservation for later scientific analysis. This article reviews proper procedures and recent cases where botanical evidence played a role in establishing either manner or time of death. Plant evidence can be useful for determining if a death was due to an accident, suicide, or homicide, or what time of year burial may have taken place. In addition, plant evidence can be used to determine if a crime scene is a primary or secondary scene and to locate missing bodies.

Evolutionary computation in zoology and ecology.

Science.gov (United States)

Boone, Randall B

2017-12-01

Evolutionary computational methods have adopted attributes of natural selection and evolution to solve problems in computer science, engineering, and other fields. The method is growing in use in zoology and ecology. Evolutionary principles may be merged with an agent-based modeling perspective to have individual animals or other agents compete. Four main categories are discussed: genetic algorithms, evolutionary programming, genetic programming, and evolutionary strategies. In evolutionary computation, a population is represented in a way that allows for an objective function to be assessed that is relevant to the problem of interest. The poorest performing members are removed from the population, and remaining members reproduce and may be mutated. The fitness of the members is again assessed, and the cycle continues until a stopping condition is met. Case studies include optimizing: egg shape given different clutch sizes, mate selection, migration of wildebeest, birds, and elk, vulture foraging behavior, algal bloom prediction, and species richness given energy constraints. Other case studies simulate the evolution of species and a means to project shifts in species ranges in response to a changing climate that includes competition and phenotypic plasticity. This introduction concludes by citing other uses of evolutionary computation and a review of the flexibility of the methods. For example, representing species' niche spaces subject to selective pressure allows studies on cladistics, the taxon cycle, neutral versus niche paradigms, fundamental versus realized niches, community structure and order of colonization, invasiveness, and responses to a changing climate.

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

Science.gov (United States)

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.

Botany and topography: the problem of the levelling of plants in the scientific historiography on Francisco José de Caldas

Directory of Open Access Journals (Sweden)

María Alejandra Puerta Olaya,

2017-07-01

Full Text Available The levelling of plants is usually recognized as one of the main concepts in the works and the thought of Francisco José de Caldas. There are different interpretations about this concept, but in general, the treatment is not very careful and does not really go into the details concerning its theoretical assumptions and consequences. In this article, we identify the diverse interpretations that historians have offered regarding the origin, the function and the definition of this concept. Our interest is to show the difficulties that the scientific historiography on Caldas faces when it deals with this concept, and how these difficulties generate uncertainty concerning the coherence that may exist between those different interpretations. In particular, we defend the thesis that the approach to the term “levelling of plants” has been focused more on the plants part than on the levelling part, that is, more on botany than on topography. This historiographic assumption has led to the construction of historical narratives that, despite the explicit topographic dimension of the term, place it in the history of botany and not in the history of topography.

A survey of literature on the use of radioactive isotopes in agriculture published between 1973 and 1980, including South African publications, was compiled by the Atomic Energy Board in 1980 but did not include any review of the scientific material

C.E.B.A.S., a closed equilibrated biological aquatic system as a possible precursor for a long-term life support system?

Science.gov (United States)

Blüm, V.

C.E.B.A.S.-AQUARACK is a long-term multi-generation experimental device for aquatic organisms which is disposed for utlizitation in a space station. It results from the basic idea of a space aquarium for maintaining aquatic animals for longer periods integrated in a AQUARACK which consists of a modular animal holding tank, a semi-biological/physical water recycling system and an electronical control unit. The basic idea to replace a part of the water recycling system by a continuous culture of unicellular algae primarily leads to a second system for experiments with algae, a botanical AQUARACK consisting of an algal reactor, a water recycling and the electronical control unit. The combination of the zoological part, and the botanical part with a common control system in the AQUARACK, however, results in a ``Closed Equilibrated Biological Aquatic System'' (C.E.B.A.S.) representing an closed artificial ecosystem. Although this is disposed primarily as an experimental device for basic zoological, botanical and interdisciplinary research it opens the theoretical possibility to adapt it for combined production of animal and plant biomass on ground or in space. The paper explains the basic conception of the hardware construction of the zoological part of the system, the corresponding scientific frame program including the choice of the experimental animals and gives some selected examples of the hardware-related resrearch. It furtheron discusses the practical and economical relevance of the system in the development of a controlled aquatical life support system in general.

The teaching of evolution in Portugal in the early 20th century through the programs and textbooks of Zoology

Directory of Open Access Journals (Sweden)

Bento CAVADAS

2011-11-01

Full Text Available The teaching of evolution in the Portuguese secondary schools is not yet fully understood. This research aimed to contribute to this clarification, in the framework of the history of the curriculum and the biology subject, by showing the expressions of the evolutionism teaching in the first three decades of the twentieth century. To this end we analyzed the programs of Zoology of 1905 and 1919, as well as two textbooks, entitled «Lições de Zoologia» and written by Bernardo Aires in accordance with these programs. This analysis showed that the study of evolution, eliminated from the program in 1905, was again recognized in the program in 1919. In textbooks, the exposure of evolution focused on the subject of evolution, in the grounds of competition and natural selection, adaptation, the biogenetic law and the essential differences between Lamarckism and Darwinism. The comparative study of these textbooks showed that the text which addresses the evolution is essentially Darwinian. However, neoLamarckians sections have been identified that show the influence of the «eclipse of Darwinism» on the teaching of evolutionism.

Using synoptic weather types to predict visitor attendance at Atlanta and Indianapolis zoological parks

Science.gov (United States)

Perkins, David R.

2018-01-01

Defining an ideal "tourism climate" has been an often-visited research topic where explanations have evolved from global- to location-specific indices tailored to tourists' recreational behavior. Unfortunately, as indices become increasingly specific, they are less translatable across geographies because they may only apply to specific activities, locales, climates, or populations. A key need in the future development of weather and climate indices for tourism has been a translatable, meteorologically based index capturing the generalized ambient atmospheric conditions yet considering local climatology. To address this need, this paper tests the applicability of the spatial synoptic classification (SSC) as a tool to predict visitor attendance response in the tourism, recreation, and leisure (TRL) sector across different climate regimes. Daily attendance data is paired with the prevailing synoptic weather condition at Atlanta and Indianapolis zoological parks from September 2001 to June 2011, to review potential impacts ambient atmospheric conditions may have on visitor attendances. Results indicate that "dry moderate" conditions are most associated with high levels of attendance and "moist polar" synoptic conditions are most associated with low levels of attendance at both zoological parks. Comparing visitor response at these zoo locations, visitors in Indianapolis showed lower levels of tolerance to synoptic conditions which were not "ideal." Visitors in Indianapolis also displayed more aversion to "polar" synoptic regimes while visitors in Atlanta displayed more tolerance to "moist tropical" synoptic regimes. Using a comprehensive atmospheric measure such as the SSC may be a key to broadening application when assessing tourism climates across diverse geographies.

De Liberato, Claudio; Berrilli, Federica; Meoli, Roberta; Friedrich, Klaus G; Di Cerbo, Pilar; Cocumelli, Cristiano; Eleni, Claudia

2014-10-01

A case of fatal infection caused by larval forms of Taenia martis in a ring-tailed lemur (Lemur catta) living in the Rome zoological garden is described. The animal, living in a semi-natural pen with other 15 conspecific individuals and being fed with fresh fruit and vegetables, yoghurt and eggs, was transported to the Istituto Zooprofilattico of Rome for post-mortem examination. The anamnesis included, ten days before the death, apathy, lack of appetite, abdominal distension and diarrhoea. A severe exudative fibrinous-purulent peritonitis with numerous adhesions between the abdominal wall and the bowel loops was detected. After intestine removal, two free and viable, 4 cm long, whitish, leaf-like parasitic forms were pinpointed. Macroscopic examination of the two parasites allowed their identification as larval stages of cestodes, identified via molecular analysis as T. martis metacestodes. This report represents the first record of T. martis infection in the host species and in a zoological garden and for the pathological relevance of the infection.

El hombre como animal: el antropocentrismo en la zoología

Directory of Open Access Journals (Sweden)

Viejo Montesinos, José Luis

1996-12-01

Full Text Available Zoological taxonomy and nomenclature have always been subject to great anthropocentrism. Since Linnaeus, most of classifications place Man in a preeminent and unique position among animals, may be as a Greek culture heritage ("Man is the measure of everything". This prejudice has sometimes given rise to an ethnocentric explanation of the evolution and human paleontology.

La taxonomía y la nomenclatura zoológicas han estado siempre sometidas a un considerable antropocentrismo. Desde Linneo, la mayoría de las clasificaciones colocan al hombre en un lugar preeminente y único entre los animales, quizá como herencia de la cultura griega ("El hombre es la medida de todas las cosas". Este prejuicio ha conducido a veces hacia una interpretación etnocéntrica de la evolución y la paleontología humana.

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

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

Science.gov (United States)

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.

Iron storage disease (ISD) is now recognized as a serious clinical disorder acquired by two species of browsing rhinoceroses, the African black (Diceros bicornis) and the Asian Sumatran (Dicerorhinus sumatrensis) rhinoceroses, when displaced from their natural habitats. The most complete knowledge of ISD comes from studies of the black rhinoceros, but the Asian species is also at risk. Sumatran rhinoceroses housed in traditional zoological settings outside of range countries have suffered significant morbidity and mortality potentially related to ISD induced by diet and/or other confinement conditions. With so few animals in captivity, very little information exists on iron loading in the Sumatran rhinoceros. To better characterize the problem, we retrospectively compared captive management conditions of Sumatran rhinoceroses housed under traditional zoological care with those in two native sanctuary environments. In general, zoo rhinoceroses are offered a paucity of plants and browse species compared with their sanctuary and wild counterparts managed in native rainforest habitats. Iron analyte levels and limited histopathologic observations in these populations suggest variable tendencies to overload iron, dependent upon differences in managed diet and individual food preferences. More detailed investigation of these markedly dissimilar ex situ populations is warranted to better understand the role of nutrition and other conditions affecting iron loading in browser rhinoceroses.

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 coevolved 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.

Panax notoginseng (Burk.) F.H. Chen is a widely used traditional Chinese medicine known as Sanqi or Tianqi in China. This plant, which is distributed primarily in the southwest of China, has wide-ranging pharmacological effects and can be used to treat cardiovascular diseases, pain, inflammation and trauma as well as internal and external bleeding due to injury. This paper provides up-to-date information on investigations of this plant, including its botany, ethnopharmacology, phytochemistry, pharmacology and toxicology. The possible uses and perspectives for future investigation of this plant are also discussed. The relevant information on Panax notoginseng (Burk.) F.H. Chen was collected from numerous resources, including classic books about Chinese herbal medicine, and scientific databases, including Pubmed, SciFinder, ACS, Ebsco, Elsevier, Taylor, Wiley and CNKI. More than 200 chemical compounds have been isolated from Panax notoginseng (Burk.) F.H. Chen, including saponins, flavonoids and cyclopeptides. The plant has pharmacological effects on the cardiovascular system, immune system as well as anti-inflammatory, anti-atherosclerotic, haemostatic and anti-tumour activities, etc. Panax notoginseng is a valuable traditional Chinese medical herb with multiple pharmacological effects. This review summarizes the botany, ethnopharmacology, phytochemistry, pharmacology and toxicology of P. notoginseng, and presents the constituents and their corresponding chemical structures found in P. notoginseng comprehensively for the first time. Future research into its phytochemistry of bio-active components should be performed by using bioactivity-guided isolation strategies. Further work on elucidation of the structure-function relationship among saponins, understanding of multi-target network pharmacology of P. notoginseng, as well as developing its new clinical usage and comprehensive utilize will enhance the therapeutic potentials of P. notoginseng.

2015-10-01

Full Text Available Staphylococcus aureus is a part of the microbiota flora in many animal species. The clonal spread of S. aureus among animals and personnel in a Zoological Park was investigated. Samples were collected from colonized and infected sites among 32 mammals, 11 birds and eight humans. The genes mecA, mecC, lukF/lukS-PV (encoding Panton-Valentine leukocidin, PVL and tst (toxic shock syndrome toxin-1 were investigated by PCR. Clones were defined by Multilocus Sequence Typing (MLST, spa type and Pulsed-Field Gel Electrophoresis (PFGE. Seven S. aureus isolates were recovered from four animals and one from an employee. All were mecA, mecC and tst–negative, whereas, one carried the PVL genes and was isolated from an infected Squirrel monkey. Clonal analysis revealed the occurrence of seven STs, eight PFGE and five spa types including ones of human origin. Even though a variety of genotypes were identified among S. aureus strains colonizing zoo park residents, our results indicate that colonization with human lineages has indeed occurred.

Full Text Available The determination of Chlamydia psittaci (Cp in psittacida birds in zoological parks in Venezuela represents a strategy of conservation and preservation for this group of birds, where multiple species are threatened with extinction and others have lost their capacity of reincorporation to their natural habitat. Through the nested polymerase chain reaction (PCR the 16S subunit of Cp DNAr was amplified in 50 cloacal swab samples from psittacine birds, reporting a frequency of 62 %. The work was carried out in the Zoo Park  Las Delicias (PZD 8% and the Aquarium of Valencia (AV 54%.  The high frequency was associated with a genotype of low concentration and virulence due to the absence of clinical signs of avian chlamydiosis.  These results demonstrate the need to promote the detection of Cp, mainly for the AV that acts as a center of reception of specimens of confiscation, and, like the PZD, have other species vulnerable to extinction with risk of infection to Cp.

Differences between epiphytic assemblages on introduced Caulerpa taxifolia and coexisting eelgrass (Zostera capricorni in Botany Bay (NSW, Australia

Full Text Available A preliminary study was conducted to assess the potential effects of introduced Caulerpa taxifolia (Caulerpales, Chlorophyta on the biodiversity and trophic functioning of seagrass systems in New South Wales, Australia. Epiphytic assemblages growing on fronds of C. taxifolia were compared to those on eelgrass Zostera capricorni (Aschers. leaves in zones where both species were coexisting. The study was conducted at three shallow sites (ca. 1 m depth in Botany Bay during austral spring. Assemblages on both C. taxifolia and Z. capricorni were dominated by epiphytic algae (ca. 65% of the total taxa but results showed significantly greater numbers on C. taxifolia compared to Z. capricorni as well as important differences among study sites. n-MDS ordinations and PERMANOVA analyses confirmed the existence of significant differences in the assemblage compositions of C. taxifolia and Z. capricorni as well as differences between times and sites. SIMPER analysis showed that animal composition made a higher contribution to dissimilarities between habitats compared to epiphytic algae (36% vs. 23% respectively. In particular, filter-feeding organisms, associated with surfaces such as ascidians (5 taxa and bryozoans (2 taxa emerged as important contributing taxa. Hence, our results suggest that introduced C. taxifolia from Botany Bay is a suitable substratum for settlement of epiphytes, at least during the study period, and that observed patterns are due to differences in habitat structure. Further research is necessary to determine the influence of seasonal processes, such as production of toxic secondary metabolites, in other invaded locations of New South Wales.

Plants are attractive platforms for synthetic biology and metabolic engineering. Plants' modular and plastic body plans, capacity for photosynthesis, extensive secondary metabolism, and agronomic systems for large-scale production make them ideal targets for genetic reprogramming. However, efforts in this area have been constrained by slow growth, long life cycles, the requirement for specialized facilities, a paucity of efficient tools for genetic manipulation, and the complexity of multicellularity. There is a need for better experimental and theoretical frameworks to understand the way genetic networks, cellular populations, and tissue-wide physical processes interact at different scales. We highlight new approaches to the DNA-based manipulation of plants and the use of advanced quantitative imaging techniques in simple plant models such as Marchantia polymorpha. These offer the prospects of improved understanding of plant dynamics and new approaches to rational engineering of plant traits.

Teacher experiences in the use of the "Zoology Zone" multimedia resource in elementary science

Science.gov (United States)

Paradis, Lynne Darlene

This interpretive research study explored the experiences of teachers with the use of the Zoology Zone multimedia resource in teaching grade three science. Four generalist teachers used the multimedia resource in the teaching of the Animal Life Cycle topic from the Alberta grade three science program. The experiences of the teachers were examined through individual interviews, classroom visits and group interviews. Three dimensions of the study, as they related to elementary science teaching using the Zoology Zone multimedia resource were examined: (a) technology as a teaching resource, (b) science education and constructivist theory, and (c) teacher learning. In the area of planning for instruction, the teachers found that using the multimedia resource demanded more time and effort than using non-computer resources because of the dependence teachers had on others for ensuring access to computer labs and setting up the multimedia resource to run on school computers. The teachers felt there was value in giving students the opportunity to independently explore the multimedia resource because it captured their attention, included appropriate content, and was designed so that students could navigate through the teaming activities easily and make choices about how to proceed with their own learning. Despite the opportunities for student directed learning, the teachers found that it was also necessary to include some teacher directed learning to ensure that students were learning the mandated curriculum. As the study progressed, it became evident that the teachers valued the social dimensions of learning by making it a priority to include lessons that encouraged student to student interaction, student to teacher interaction, small group and whole class discussion, and peer teaching. When students were engaged with the multimedia resource, the teacher facilitated learning by circulating to each student and discussing student findings. Teachers focussed primarily on the

DAS, Bidhan C

2009-06-01

It is now well recognized that Bangladesh is one of the world's most vulnerable countries to climate change and sea level rise. Low levels of natural resources and a high occurrence of natural disasters further add to the challenges faced by the country. The impacts of climate change are anticipated to exacerbate these existing stresses and constitute a serious impediment to poverty reduction and economic development. Ecosystems and biodiversity are important key sectors of the economy and natural resources of the country are selected as the most vulnerable to climate change. It is for these reasons that Bangladesh should prepare to conserve its natural resources under changed climatic conditions. Unfortunately, the development of specific strategies and policies to address the effects of climate change on the ecosystem and on biodiversity has not commenced in Bangladesh. Here, I present a detailed review of animal resources of Bangladesh, an outline of the major areas in zoological research to be integrated to adapt to climate change, and identified few components for each of the aforesaid areas in relation to the natural resource conservation and management in the country. © 2009 ISZS, Blackwell Publishing and IOZ/CAS.

Bichalcophene fluorobenzonitriles 4a–e were prepared adopting a Stille coupling reaction between the bromo compounds 3a–c and 2-(tri-n-butylstannylfuran or analogues. As an approach to drug discovery, the structure–antimutagenicity relationship of novel fluoroarylbichalcophenes was examined using the Ames Salmonella/microsomal assay. At nontoxic concentrations (10 and 20 µM, all derivatives alone or in combination with sodium azide (NaN3; 2 µg/plate or benzo[a]pyrene (B[a]P; 20 µM in the presence of S9 mix were not mutagenic. The fluoroaryl derivatives significantly reduced the NaN3-induced and B[a]P-induced mutagenicity under pre-exposure and co-exposure conditions. The recorded antimutagenic activity of fluoroaryl derivatives varied depending on the kind of mutagen and the exposure regimen. Monocationic fluoroarylbichalcophenes were superior to the corresponding mononitriles in reducing B[a]P-induced mutagenicity. Nevertheless, mononitriles were more active against NaN3, especially at low concentrations and under pre-exposure treatments. The antimutagenic activity was congruent with a high antioxidant activity that could promote the DNA

2013-10-01

Full Text Available The small hive beetle Aethina tumida is an endemic parasitic pest and scavenger of colonies of social bees indigenous to sub-Saharan Africa. In this region this species rarely inflicts severe damage on strong colonies since the bees have develo­­ped strategies to combat them. However, A. tumida has since ‘escaped’ from its native home and has recently invaded areas such as North America and Australia where its economic impact on the apiculture industry has been significant. Small hive beetle, should it become established within Europe, represents a real and live threat to the UK bee keeping industry. Here we review the biology and current pest status of A. tumida and up to-date research in terms of both chemical and biological control used against this honey bee pest [Current Zoology 59 (5: 644–653, 2013].

Biogeography

Quattrochi, Dale A.; Arnold, James E. (Technical Monitor)

2002-01-01

As a field of study, biogeography may be considered a bricolage - it has been constructed from many different facets from an array of research disciplines including biology, botany, zoology, geography, and geology. Biogeography focuses on the study of the constantly changing ranges of plants and animals, over multitude of space and time scales. It also includes the study of the structure and dynamics of biotic communities and ecosystems as they relate to both natural and anthropogenic processes. As it exists today, biogeography is an interdisciplinary research area founded in both the biological and Earth sciences. From a purely biological perspective, biogeography may be perceived as one of two types of studies: 1. biotic distributions and broad scales, and interpretations of the evolutionary and dispersal history of a single taxon or a few taxa; or 2. biotic distributions at local-to-regional scales, and interpretations of these distributions in relation to contemporary environments and rates of immigration or extinction. The first type of study is what is most usually associated with the term "biogeography" as disciplinary research field. It is conventionally termed "classical biogeography" because it reflects the continuity of research foci on which biogeography was founded in the nineteenth-century. The second type of biogeographical study has more modern day roots and is termed "geographical ecology" to reflect the theoretical predilections of ecologists and population biologists. Geographical ecology for all intents has become merged with ecology and exists as a sub discipline within this larger field of study.

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

1979-11-01

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.

Central America is recognized as a mega diverse "hot-spot" and one of its smaller countries, Costa Rica, as one of the world's leaders in the study and conservation of tropical biodiversity. For this study, inspired by the 60th anniversary of the journal Revista de Biología Tropical, we tabulated all the scientific production on Costa Rican biodiversity published in Revista de Biología Tropical between 2000 and 2010. Most articles are zoological (62%) and 67% of authors had only one publication in the jounal within that period. A 54% of articles were published in English and 46% in Spanish. A 41% of articles were written in collaboration among Costa Rican institutions and 36% in collaboration with foreign institutions. The Collaboration Index was 2.53 signatures per article. Visibility in American sources was 56% in Google Scholar and 42.66% in the Web of Science, but the real visibility and impact are unknown because these sources exclude the majority of tropical journals. Revista de Biología Tropical is the main output channel for Costa Rican biology and despite its small size, Costa Rica occupies the 10th. place in productivity among Latin American countries, with productivity and impact levels that compare favorably with larger countries such as Brazil, Mexico, Argentina and Chile.

Under natural conditions bottlenose dolphins (Tursiops truncatus) spend their time mostly feeding and then travelling, socializing, or resting. These activities are not randomly distributed, with feeding being higher in early morning and late afternoon. Social activities and vocal behavior seem to be very important in dolphin daily activity. This study aimed to describe the activity time-budget and its relation to vocal behavior for dolphins in a zoological park. We recorded behaviors and vocalizations of six dolphins over 2 months. All subjects performed more non-agonistic social interactions and play in the morning than in the afternoon. The different categories of vocalizations were distributed non-randomly throughout the day, with more chirps in the afternoon, when the animals were "less social." The most striking result was the strong correlation between activities and the categories of vocalizations produced. The results confirm the association between burst pulses and whistles with social activities, but also reveal that both are also associated with solitary play. More chirps were produced when dolphins were engaged in socio-sexual behaviors, emphasizing the need for further questioning about the function of this vocal category. This study reveals that: (i) in a group kept in zoological management, social activities are mostly present in the morning; and (ii) the acoustic signals produced by dolphins may give a reliable representation of their current activities. While more studies on the context of signal production are needed, our findings provide a useful tool for understanding free ranging dolphin behavior when they are not visible. © 2017 Wiley Periodicals, Inc.

capacity, both in the field of botany and of zoology. Among the new methods to improve the characteristics and dissemination of plants we find the regeneration techniques of plants in vitro, including the organogenesis and the somatic embriogenesis that give the possibility to form the so-called “artificial seeds”. In zoology, it has been observed the regenerative capacity of some animals, such as planarians, hydras, starfish and crustacean. Many vertebrates have lost, at least in a significant way, the regenerative potentiality of most of their organs and tissues. However, some have retained a marked regenerative ability, among them, the Teleostei, the Urodela (salamanders and tritons and other types of amphibia. The Chelonia, crocodriles and snakes have lost in general the capacity to regenerate lost parts. Alligators have the possibility to regenerate their tails. Mammals have also limitations, since they cannot regenerate extremities, organs and tissues as some inferior animals do. There are exceptions, as those found in stags, dolphins and some type of mice as the MRL mice. The human being expresses only some physiological regenerative processes, or before some injuries that are mainly manifested in the epidermal cells of the oral mucosa and of the respiratory tract, the blood cells, the hair, the nails, the muscular tissue, the skin and the bone tissue.

St. George Mivart as Popularizer of Zoology in Britain and America, 1869-1881.

Recent scholarly attentions have shifted from key actors within the scientific elite and religious authorities to scientific practitioners and popularizers who used science to pursue a wide variety of cultural purposes. The Roman Catholic zoologist St. George Mivart (1827-1900) has typically been cast as a staunch anti-Darwinian ostracized by Darwin's inner circle of scientific naturalists. Understood as a popularizer of science, his position can be re-thought. Mivart did not operate on the periphery of Victorian science. Instead, his notable contributions to the fields of zoology and anatomy and his participation in debates about the origin of the human mind, consciousness, and soul made him a central figure in the changing landscape of late-Victorian scientific culture. Through the popular periodical press and his anatomy textbook for beginners, Mivart secured a reputation as a key spokesman for science and gained authority as a leading critic of agnostic scientific naturalism.

On names of genera of prokaryotes that are later homonyms of generic names with standing in the zoological or the botanical nomenclature. Proposal of Neomegalonema gen. nov. and Neomegalonema perideroedes comb. nov. as replacements for the prokaryotic generic name Meganema and the species name Meganema perideroedes.

I here present a survey of generic names with standing in the prokaryotic nomenclature that have homonyms with standing under the International Code of Zoological Nomenclature and/or the International Code of Nomenclature for algae, fungi, and plants. I especially discuss such names added after Principle 2 of the Bacteriological Code/Prokaryotic Code was changed in 1999 to make the prokaryote nomenclature not independent of botanical and zoological nomenclature. Cases include the genera Micromonas, Quadrococcus, Yania, Sinococcus, and Meganema. The generic name Meganema was not previously recognized as a homonym of two genera with standing in the zoological nomenclature. Therefore, I here propose renaming Meganema and Meganema perideroedes as Neomegalonema gen. nov. and Neomegalonema perideroedes comb. nov., respectively.

Activation Analysis in Botany and Agriculture. Survey Paper

Energy Technology Data Exchange (ETDEWEB)

Bowen, H. J.M. [University of Reading, Reading, Berks. (United Kingdom)

1967-10-15

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, {alpha}) 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

On New Spain and Mexican medicinal botany in cardiology.

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.

Botany on a plate. Pleasure and the power of pictures in promoting early nineteenth-century scientific knowledge.

Secord, Anne

2002-03-01

In early nineteenth-century Britain the use of pictures in introducing novices to the study of science was contentious, leading to debates over the ways in which words and images constituted knowledge and over the role of pleasure in intellectual pursuits. While recent studies have stressed visual representation as a critical element of science and considered its relation to the written word in conveying information, this essay explores the nineteenth-century preoccupation with the mind and mental faculties in relation to corporeal responses to explain concerns over the role of images and the process of recognition. By considering illustration in this way, it argues that popular botany was defined by many expert naturalists as the means by which private individuals could best be encouraged to extend their aesthetic appreciation and love of plants to an active and participatory pursuit of science.

From Charles Darwin's botanical country-house studies to modern plant biology.

As a student of theology at Cambridge University, Charles Darwin (1809-1882) attended the lectures of the botanist John S. Henslow (1796-1861). This instruction provided the basis for his life-long interest in plants as well as the species question. This was a major reason why in his book On the Origin of Species, which was published 150 years ago, Darwin explained his metaphorical phrase 'struggle for life' with respect to animals and plants. In this article, we review Darwin's botanical work with reference to the following topics: the struggle for existence in the vegetable kingdom with respect to the phytochrome-mediated shade avoidance response; the biology of flowers and Darwin's plant-insect co-evolution hypothesis; climbing plants and the discovery of action potentials; the power of movement in plants and Darwin's conflict with the German plant physiologist Julius Sachs; and light perception by growing grass coleoptiles with reference to the phototropins. Finally, we describe the establishment of the scientific discipline of Plant Biology that took place in the USA 80 years ago, and define this area of research with respect to Darwin's work on botany and the physiology of higher plants.

A capital Scot: microscopes and museums in Robert E. Grant's zoology (1815-1840).

Science.gov (United States)

Quick, Tom

2016-06-01

Early nineteenth-century zoology in Britain has been characterized as determined by the ideological concerns of its proponents. Taking the zoologist Robert E. Grant as an exemplary figure in this regard, this article offers a differently nuanced account of the conditions under which natural-philosophical knowledge concerning animal life was established in post-Napoleonic Britain. Whilst acknowledging the ideological import of concepts such as force and law, it points to an additional set of concerns amongst natural philosophers - that of appropriate tool use in investigation. Grant's studies in his native Edinburgh relied heavily on the use of microscopes. On his arrival in London, however, he entered a culture in which a different set of objects - museum specimens - held greater persuasive power. This article relates changes in Grant's ideas and practices to the uneven emphases on microscopic and museological evidence amongst European, Scottish and English natural philosophers at this time. In so doing, it identifies the reliance of London-based natural philosophers on museology as constituting a limiting effect on the kinds of claim that Grant sought to make regarding the nature of life.

Modernizing Natural History: Berkeley's Museum of Vertebrate Zoology in Transition.

Science.gov (United States)

Sunderland, Mary E

2013-01-01

Throughout the twentieth century calls to modernize natural history motivated a range of responses. It was unclear how research in natural history museums would participate in the significant technological and conceptual changes that were occurring in the life sciences. By the 1960s, the Museum of Vertebrate Zoology at the University of California, Berkeley, was among the few university-based natural history museums that were able to maintain their specimen collections and support active research. The MVZ therefore provides a window to the modernization of natural history. This paper concentrates on the directorial transitions that occurred at the MVZ between 1965 and 1971. During this period, the MVZ had four directors: Alden H. Miller (Director 1940-1965), an ornithologist; Aldo Starker Leopold (Acting Director 1965-1966), a conservationist and wildlife biologist; Oliver P. Pearson (Director 1966-1971), a physiologist and mammalogist; and David B. Wake (Director 1971-1998), a morphologist, developmental biologist, and herpetologist. The paper explores how a diversity of overlapping modernization strategies, including hiring new faculty, building infrastructure to study live animals, establishing new kinds of collections, and building modern laboratories combined to maintain collections at the MVZ's core. The paper examines the tensions between the different modernization strategies to inform an analysis of how and why some changes were institutionalized while others were short-lived. By exploring the modernization of collections-based research, this paper emphasizes the importance of collections in the transformation of the life sciences.

Baird, J. Hugh; Lazarowitz, Reuven; Allman, Verl

This research sought to answer two questions: (1) What are Utah junior and senior high school students' preferences and choices regarding science subjects? (2) Could preferences and choices be related to the type of school, age or gender? Two thousand students from grades six through twelve participated in this study. Findings show that zoology and human anatomy and physiology were most preferred. Ecology was least prefered. Topics in the physical sciences were also low. There was a trend among girls to prefer natural sciences such as botany while boys tended to prefer the physical sciences. Generally, students' choices were limited to those subjects presently taught in the formal school curriculum. They appeared unaware of the many science related subjects outside the texts or the approved course of study.

Historical Contribution of Pharmaceutics to Botany and Pharmacognosy Development.

Pharmacy and medicine belong to the oldest human activities, so the development of these sciences is closely related to the socio-economic, cultural and religious opportunities of the nations within which they have been developing. To present the historical influence of pharmacy on the development of the human being from its very beginning; To present the historical link between pharmaceutical and medical activity, as well as early development of independent pharmaceutical activity; To present the historical influence of pharmacists on the development of botany and pharmacognosy and to present the historical influence of the first written herbarium and incunabula on the development of pharmacognosy. The article has a descriptive character, and represents a systematic review of the literature dealing with this topic. The roots of pharmacy started to the very beginning of human civilization, when people collected various medicinal herbs and try to alleviate their health problems, pain and suffering. The scientific foundations of the pharmacy were set up in the antique period by the books of Dioskurides and Galen, and its further development continued in the mid-century, at the beginning by rewriting famous parts of ancient literature, and later by writing new discoveries (the base of this development was represented by South Italy) so that in 1240, for the first time in history, came the separation of doctors and pharmacists, and at the beginning of the 13th century the opening of the first pharmacy. The effort to maintain knowledge of medicinal herbs and its practical application has led to the writing of a large number of recipes books, the forerunners of today's pharmacopeia, while the aspiration to classify medicinal herbs, and the desire to present medicinal herbs to ordinary people, has led to a large number of herbaria, making the knowledge and descriptions of plants available to many, not just the nobility.

The fruit of Illicium verum Hook. f. (Chinese star anise) has long been used in traditional Chinese medicine and food industry with the actions of dispelling cold, regulating the flow of Qi and relieving pain. A bibliographic investigation was carried out by analyzing recognized books including Chinese herbal classic, and worldwide accepted scientific databases (Pubmed, SciFinder, Scopus and Web of Science) were searched for the available information on I. verum. I. verum is an aromatic evergreen tree of the family Illiciaceae. It is sometimes contaminated with highly toxic Japanese star anise (I. anisatum L.) and poisonous star anise (I. lanceolatum A. C. Smith), which contain several neurotoxic sesquiterpenes. Traditional uses of I. verum are recorded throughout Asia and Northern America, where it has been used for more than 10 types of disorders. Numerous compounds including volatiles, seco-prezizaane-type sesquiterpenes, phenylpropanoids, lignans, flavonoids and other constituents have been identified from I. verum. Modern pharmacology studies demonstrated that its crude extracts and active compounds possess wide pharmacological actions, especially in antimicrobial, antioxidant, insecticidal, analgesic, sedative and convulsive activities. In addition, it is the major source of shikimic acid, a primary ingredient in the antiflu drug (Tamiflu). This review summarizes the up-to-date and comprehensive information concerning the botany, traditional use, phytochemistry and pharmacology of I. verum together with the toxicology, and discusses the possible trend and scope for future research of I. verum.

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

Science.gov (United States)

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.

Examples and citations are provided for each case one can encounter while making this assessment of availability status of names following the binomen.

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

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.

How theories became knowledge: Morgan's chromosome theory of heredity in America and Britain.

Science.gov (United States)

Brush, Stephen G

2002-01-01

T. H. Morgan, A. H. Sturtevant, H. J. Muller and C. B. Bridges published their comprehensive treatise The Mechanism of Mendelian Heredity in 1915. By 1920 Morgan's "Chromosome Theory of Heredity" was generally accepted by geneticists in the United States, and by British geneticists by 1925. By 1930 it had been incorporated into most general biology, botany, and zoology textbooks as established knowledge. In this paper, I examine the reasons why it was accepted as part of a series of comparative studies of theory-acceptance in the sciences. In this context it is of interest to look at the persuasiveness of confirmed novel predictions, a factor often regarded by philosophers of science as the most important way to justify a theory. Here it turns out to play a role in the decision of some geneticists to accept the theory, but is generally less important than the CTH's ability to explain Mendelian inheritance, sex-linked inheritance, non-disjunction, and the connection between linkage groups and the number of chromosome pairs; in other words, to establish a firm connection between genetics and cytology. It is remarkable that geneticists were willing to accept the CTH as applicable to all organisms at a time when it had been confirmed only for Drosophila. The construction of maps showing the location on the chromosomes of genes for specific characters was especially convincing for non-geneticists.

The body showed widespread electrical lesions. The statements of his brother and wife about the incident aroused a large amount of suspicion in the investigators. A crime scene investigation was carried out, along with a botanical morphological survey on small vegetations found on the corpse. An autopsy was also performed. Botanical analysis showed some samples of Xanthium spinosum, thus leading to the discovery of the falsification of the crime scene although the location of the true crime scene remained a mystery. The botanical analysis, along with circumstantial data and autopsy findings, led to the discovery of the real crime scene and became crucial as part of the legal evidence regarding the falsity of the statements made to investigators. © 2017 American Academy of Forensic Sciences.

A question of merit: John Hutton Balfour, Joseph Hooker and the 'concussion' over the Edinburgh chair of botany.

In 1845, Robert Graham's death created a vacancy for the traditionally dual appointment to the University of Edinburgh's chair of botany and the Regius Keepership of the Edinburgh Royal Botanic Garden. John Hutton Balfour and Joseph Hooker emerged as the leading candidates. The contest quickly became embroiled in long running controversies over the nature and control of Scottish university education at a time of particular social and political tension after a recent schism in Church of Scotland. The politics of the appointment were complicated by the fact that the Edinburgh Town Council (which preferred Balfour) chose the chair while the keepership was under the patronage of the Westminster government (which preferred Hooker). Balfour eventually emerged triumphant after a bitter campaign marked on all sides by intense politicking. The struggle to replace Graham provides a case study in how Victorian men of science adapted their aspirations to the practical realities of life in industrial, reforming, imperial, multinational Britain.

Abstract Bembidion (Lymnaeum) nigropiceum (Marsham) (=puritanum Hayward), a European species introduced into Massachusetts but presumed not to have become established, has been rediscovered during the Boston Harbor Islands All Taxa Biodiversity Inventory undertaken by the Museum of Comparative Zoology and the National Park Service. A summary is presented of treatment of this species in North America. Data on specimens collected are presented, along with observations on habitat and biology. Some speculations are presented about its highly specialized habitat in the gravel pushed up by high tide, which may act as a food-trapping sieve. A few words are included about future actions needed to resolve questions of distribution and behavior. PMID:22379389

Full Text Available Resumo As Ciências Naturais foram ensinadas na escola secundária pública brasileira a partir de 1837 com a fundação do Imperial Collégio de Pedro II no Rio de Janeiro. Em 1841 foi introduzida no currículo a Zoologia Filosófica, uma matéria teórica, complementar aos estudos tradicionais da Zoologia, que permaneceu até ser suprimida em 1855. A Zoologia Filosófica era uma matéria intrínseca ao Colégio de Pedro II, uma vez que não existia nos colégios brasileiros da época outra semelhante, nem mesmo nos liceus franceses. Embora não haja informações sobre os conteúdos de que tratava, tem-se o programa de exames de 1850, em que quarenta pontos são listados. Mediante uma análise dos pontos, foi possível identificar os conteúdos ensinados. A análise demonstra que, em contraste com os conceitos tradicionais da Zoologia Descritiva, a Zoologia Filosófica abordou conceitos, grandes teorias e especulações sobre a origem, as transformações e o crescimento dos animais, que circulavam na Europa, e particularmente na França, na primeira metade do século XIX. No estudo, constata-se que foi uma matéria excepcional por ser a única no Brasil a tratar da Zoologia teórica nos moldes da Naturalfilosofie, prevalecente na Alemanha e explorada na França por Étienne Geoffroy Saint-Hilaire, Étienne Serres e outros cientistas de renome.

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.

Electron probe analysis of biological fluids: Possibilities and limitations

International Nuclear Information System (INIS)

Roinel, N.

1984-01-01

Physical methods of investigation have become essential to investigations at the cellular or subcellular level. Nuclear magnetic resonance is the most recent and striking example, since it is not only a tool for fundamental physicists and organic chemists, but also an extraordinary powerful imaging tool for physicians. The absorption properties of X rays were used immediately after their discovery to image the bones of skeletons. Later, X rays were also found to be extremely efficient in the measurement of the elemental content of microvolumes irradiated by electron probes. The electron probe analyzer (EPA) was immediately adopted by numerous laboratories of metallurgy, geology, and mineral sciences. In the last fifteen years, since the use of this instrument was suggested for liquid analysis, and a preparative technique was developed, the EPA has been used by an increasing number of biological laboratories for measuring the concentrations of the elements contained in subnanoliter volumes of biological fluids. The so-called microdroplet technique has become a routine laboratory method, the only one able to measure the concentrations of an unlimited number of elements in a single 0.1-nl sample. This explains its use in fields as various as renal, reproductive, digestive, and plant physiology, zoology, etc. Several review papers discuss these applications. The possibilities and limitations of the technique are discussed below

Weather and Tourism: Thermal Comfort and Zoological Park Visitor Attendance

Directory of Open Access Journals (Sweden)

David R. Perkins

2016-03-01

Full Text Available Weather events have the potential to greatly impact business operations and profitability, especially in outdoor-oriented economic sectors such as Tourism, Recreation, and Leisure (TRL. Although a substantive body of work focuses on the macroscale impacts of climate change, less is known about how daily weather events influence attendance decisions, particularly relating to the physiological thermal comfort levels of each visitor. To address this imbalance, this paper focuses on ambient thermal environments and visitor behavior at the Phoenix and Atlanta zoos. Daily visitor attendances at each zoo from September 2001 to June 2011, were paired with the Physiologically Equivalent Temperature (PET to help measure the thermal conditions most likely experienced by zoo visitors. PET was calculated using hourly atmospheric variables of temperature, humidity, wind speed, and cloud cover from 7 a.m. to 7 p.m. at each zoological park location and then classified based on thermal comfort categories established by the American Society of Heating and Air Conditioning Engineers (ASHRAE. The major findings suggested that in both Phoenix and Atlanta, optimal thermal regimes for peak attendance occurred within “slightly warm” and “warm” PET-based thermal categories. Additionally, visitors seemed to be averse to the most commonly occurring thermal extreme since visitors appeared to avoid the zoo on excessively hot days in Phoenix and excessively cold days in Atlanta. Finally, changes in the daily weather impacted visitor attendance as both zoos experienced peak attendance on days with dynamic changes in the thermal regimes and depressed attendances on days with stagnant thermal regimes. Building a better understanding of how weather events impact visitor demand can help improve our assessments of the potential impacts future climate change may have on tourism.

A molecular identification system for grasses: a novel technology for forensic botany.

Ward, J; Peakall, R; Gilmore, S R; Robertson, J

2005-09-10

Our present inability to rapidly, accurately and cost-effectively identify trace botanical evidence remains the major impediment to the routine application of forensic botany. Grasses are amongst the most likely plant species encountered as forensic trace evidence and have the potential to provide links between crime scenes and individuals or other vital crime scene information. We are designing a molecular DNA-based identification system for grasses consisting of several PCR assays that, like a traditional morphological taxonomic key, provide criteria that progressively identify an unknown grass sample to a given taxonomic rank. In a prior study of DNA sequences across 20 phylogenetically representative grass species, we identified a series of potentially informative indels in the grass mitochondrial genome. In this study we designed and tested five PCR assays spanning these indels and assessed the feasibility of these assays to aid identification of unknown grass samples. We confirmed that for our control set of 20 samples, on which the design of the PCR assays was based, the five primer combinations produced the expected results. Using these PCR assays in a 'blind test', we were able to identify 25 unknown grass samples with some restrictions. Species belonging to genera represented in our control set were all correctly identified to genus with one exception. Similarly, genera belonging to tribes in the control set were correctly identified to the tribal level. Finally, for those samples for which neither the tribal or genus specific PCR assays were designed, we could confidently exclude these samples from belonging to certain tribes and genera. The results confirmed the utility of the PCR assays and the feasibility of developing a robust full-scale usable grass identification system for forensic purposes.

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

Science.gov (United States)

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. Copyright © 2014 Elsevier Ltd. All rights reserved.

Full Text Available In the latter part of the XIX century Don Vicente Fernández, professor of the Colegio del Estado, proposed that a journal should be edited covering scientific themes such as mathematics, physics, chemistry, zoology, botany, mineralogy and astronomy. His idea became a reality when in 1991 the Universidad de Guanajuato edited a journal,Acta Universitaria, with the characteristics that he had proposed. Ever since 17 issues have been published containing articles that come from different disciplines including sciences, social sciences, humanities, business and economics. A great number of these articles have been contributions of professors in the areas of agriculture, biology, chemistry, physics, medicine and engineering. In addition, other topics covered have been philosophy and other humanities. In the present article the evolution of the journal is examined to determine how many national and international articles have been published in the journal and the contribution of the academic units of the Universidad de Guanajuato as well.

Saussurea involucrata Matsum. & Koidz. is an endangered species of the Asteraceae family, growing in the high mountains of central Asia. It has been, and is, widely used in traditional Uyghur, Mongolian and Kazakhstan medicine as well as in Traditional Chinese Medicine as Tianshan Snow Lotus (Chinese: ). In traditional medical theory, S. involucrata can promote blood circulation, thereby alleviating all symptoms associated with poor circulation. It also reputedly eliminates cold and dampness from the body, diminishes inflammation, invigorates, and strengthens Yin and Yang. It has long been used to treat rheumatoid arthritis, cough with cold, stomach ache, dysmenorrhea, and altitude sickness in Uyghur and Chinese medicine. To comprehensively summarize the miscellaneous research that has been done regarding the botany, ethnopharmacology, phytochemistry, biological activity, and toxicology of S. involucrata. An extensive review of the literature was carried out. Apart from different electronic databases including SciFinder, Chinese National Knowledge Infrastructure (CNKI), ScienceDirect that were sourced for information, abstracts, full-text articles and books written in English and Chinese, including those traditional records tracing back to the Qing Dynasty. Pharmacopoeia of China and other local herbal records in Uighur, Mongolian and Kazakhstan ethnomedicines were investigated and compared for pertinent information. The phytochemistry of S. involucrata has been comprehensively investigated. More than 70 compounds have been isolated and identified; they include phenylpropanoids, flavonoids, coumarins, lignans, sesquiterpenes, steroids, ceramides, polysaccharides. Scientific studies on the biological activity of S. involucrata are equally numerous. The herb has been shown to have anti-neoplastic, anti-inflammatory, analgesic, anti-oxidative, anti-fatigue, anti-aging, anti-hypoxic, neuroprotective and immunomodulating effects. Many have shown correlations to the

Full Text Available This paper reports the results of a comparative content analysis of three evolutionary biology and three vertebrate zoology textbooks, widely adopted in higher education biology courses in many universities of Latin and Anglo-Saxon countries. Using techniques of content analysis, we performed a quali-quantitative documentary analysis of the textbooks, aiming at investigating the treatment and recontextualization of contents related to evolutionary developmental biology (evo-devo and process pluralism. Our findings indicate that the recontextualization of contents associated with process pluralism is still in an initial phase in textbooks of both disciplines, even though in a more advanced stage in evolutionary biology textbooks. Regarding evo-devo contents, recontextualization has already taken place in a more extensive manner, particularly in vertebrate zoology textbooks. These results show differences in the construction of pedagogical discourse related to the structure of academic knowledge and the research targets in these disciplines.

Full Text Available The article gives some biographical data about the authors of wonderful, landmark article on the thermal biology of the sand lizard. It was published in 1943, and in our opinion it was the first serious article on thermal biology of reptiles, which should consider the beginning of the researches in this scientific field. In 1940-s Serafima S.Lieberman and Nina V.Pokrovskaya were the students of the biological faculty of Moscow state University and worked in the Department of vertebrate zoology. Together with the whole country, they bravely endured the difficulties of the great Patriotic war and, as best they could, contributed to the victory. Their scientific supervisors were the remarkable biologists who worked at the same Department: A. M. Sergeev, Prof. A. N. Formozov and Prof. B. S. Matveev, and that perhaps helped their work to become so important. Later, however, they did not link their activities with Herpetology and worked in other fields of biology. Sima Lieberman and Nina Pokrovskaya were warm friends all their lives. Their children and grandchildren maintain good relations up today.

2016-05-01

Full Text Available The diurnal and nocturnal activity time budgets of five adult female Asian elephants (Elephas maximus were studied in a zoological park for two 24-hour, five 14-hour, and one 9-hour observation periods between May and June 2011. Relatively few studies have looked at detailed daytime and nighttime activity time budgets in captive Asian elephants. Continuous observation was used to measure the activity time budgets of at least one focal animal per observation period. The activity time budgets varied between animals and observation periods. The elephants spent 17-49% of the day (daylight hours standing, 1-9% of the day walking, 19-44% of the day eating, and 1-20% of the day using enrichment items. At night, the elephants spent 29-87% of the observation period standing, 1-19% of the night eating, and 0.1-10% of the night using enrichment items. At night, elephants spent 0-45% of the observation period lying down. Variations in activity time budgets between elephants and observation periods have been observed in other studies of captive and wild elephants. Results of this observational study allow comparison between groups of captive elephants and between captive and wild elephants. Furthermore, results of this study can inform management strategies.

DNA fingerprinting in zoology: past, present, future.

Chambers, Geoffrey K; Curtis, Caitlin; Millar, Craig D; Huynen, Leon; Lambert, David M

2014-02-03

In 1962, Thomas Kuhn famously argued that the progress of scientific knowledge results from periodic 'paradigm shifts' during a period of crisis in which new ideas dramatically change the status quo. Although this is generally true, Alec Jeffreys' identification of hypervariable repeat motifs in the human beta-globin gene, and the subsequent development of a technology known now as 'DNA fingerprinting', also resulted in a dramatic shift in the life sciences, particularly in ecology, evolutionary biology, and forensics. The variation Jeffreys recognized has been used to identify individuals from tissue samples of not just humans, but also of many animal species. In addition, the technology has been used to determine the sex of individuals, as well as paternity/maternity and close kinship. We review a broad range of such studies involving a wide diversity of animal species. For individual researchers, Jeffreys' invention resulted in many ecologists and evolutionary biologists being given the opportunity to develop skills in molecular biology to augment their whole organism focus. Few developments in science, even among the subsequent genome discoveries of the 21st century, have the same wide-reaching significance. Even the later development of PCR-based genotyping of individuals using microsatellite repeats sequences, and their use in determining multiple paternity, is conceptually rooted in Alec Jeffreys' pioneering work.

Cryptococcus neoformans, a major pathogen in immunocompromised patients, is a ubiquitous free-living fungus that can be isolated from soils, avian excreta and plant material. To further study potential saprophytic sources of this yeast in the Southern Brazilian State Rio Grande do Sul, we analyzed fecal samples from 59 species of captive birds kept in cages at a local Zoological Garden, belonging to 12 different orders. Thirty-eight environmental isolates of C. neoformans were obtained only from Psittaciformes (Psittacidae, Cacatuidae and Psittacula). Their variety and serotype were determined, and the genetic structure of the isolates was analyzed by use of the simple repetitive microsatellite specific primer M13 and the minisatellite specific primer (GACA)(4) as single primers in the PCR. The varieties were confirmed by pulsed-field gel electrophoresis (PFGE). Thirty-three isolates (87%) were from the var. grubii, serotype A, molecular type VNI and five (13%) were Cryptococcus gattii, serotype B, molecular type VGI. All the isolates were mating type alpha. Isolates were screened for some potential virulence factors. Quantitative urease production by the environmental isolates belonging to the C. gattii was similar to the values usually obtained for clinical ones.

Prevalence of Entamoeba species in captive primates in zoological gardens in the UK

Directory of Open Access Journals (Sweden)

Carl S. Regan

2014-07-01

Full Text Available The aim of this study was to determine the prevalence of amoebic infection in non-human primates (NHPs from six Zoological gardens in the United Kingdom. Initially, 126 faecal samples were collected from 37 individually identified NHPs at Twycross Zoo, UK, and were subjected to microscopic examination. A subsequent, nationwide experiment included 350 faecal samples from 89 individually identified NHPs and 73 unidentified NHPs from a number of UK captive wildlife facilities: Twycross Zoo (n = 60, Colchester Zoo (n = 3, Edinburgh Zoo (n = 6, Port Lympne Wild Animal Park (n = 58, Howletts Wild Animal Park (n = 31, and Cotswold Wildlife Park (n = 4. Samples were examined by PCR and sequencing using four specific primer sets designed to differentiate between the pathogenic E. histolytica, the non-pathogenic E. dispar, and non-pathogenic uninucleate cyst-producing Entamoeba species. In the first experiment, Entamoeba was detected in 30 primates (81.1%. Six (16.2% primates were infected with E. histolytica species complex. The highest carriage of Entamoeba species was found in Old World Colobinae primates. In the nationwide experiment, molecular analysis of faecal samples revealed notable rates of Entamoeba infection (101 samples, 28.9%, including one sample infected with E. histolytica, 14 samples with E. dispar, and 86 samples with uninucleated-cyst producing Entamoeba species. Sequences of positive uninucleated-cyst producing Entamoeba samples from Twycross Zoo clustered with the E. polecki reference sequences ST4 reported in Homo sapiens, and are widely separated from other Entamoeba species. These findings suggest a low prevalence of the pathogenic Entamoeba infection, but notable prevalence of non-pathogenic E. polecki infection in NHPs in the UK.

How biological soil crusts became recognized as a functional unit: a selective history

Science.gov (United States)

Lange, Otto L.; Belnap, Jayne

2016-01-01

It is surprising that despite the world-wide distribution and general importance of biological soil crusts (biocrusts), scientific recognition and functional analysis of these communities is a relatively young field of science. In this chapter, we sketch the historical lines that led to the recognition of biocrusts as a community with important ecosystem functions. The idea of biocrusts as a functional ecological community has come from two main scientific branches: botany and soil science. For centuries, botanists have long recognized that multiple organisms colonize the soil surface in the open and often dry areas occurring between vascular plants. Much later, after the initial taxonomic and phyto-sociological descriptions were made, soil scientists and agronomists observed that these surface organisms interacted with soils in ways that changed the soil structure. In the 1970’s, research on these communities as ecological units that played an important functional role in drylands began in earnest, and these studies have continued to this day. Here, we trace the history of these studies from the distant past until 1990, when biocrusts became well-known to scientists and the public.

Bibliometric Evidence for a Hierarchy of the Sciences.

Science.gov (United States)

Fanelli, Daniele; Glänzel, Wolfgang

2013-01-01

The hypothesis of a Hierarchy of the Sciences, first formulated in the 19(th) century, predicts that, moving from simple and general phenomena (e.g. particle dynamics) to complex and particular (e.g. human behaviour), researchers lose ability to reach theoretical and methodological consensus. This hypothesis places each field of research along a continuum of complexity and "softness", with profound implications for our understanding of scientific knowledge. Today, however, the idea is still unproven and philosophically overlooked, too often confused with simplistic dichotomies that contrast natural and social sciences, or science and the humanities. Empirical tests of the hypothesis have usually compared few fields and this, combined with other limitations, makes their results contradictory and inconclusive. We verified whether discipline characteristics reflect a hierarchy, a dichotomy or neither, by sampling nearly 29,000 papers published contemporaneously in 12 disciplines and measuring a set of parameters hypothesised to reflect theoretical and methodological consensus. The biological sciences had in most cases intermediate values between the physical and the social, with bio-molecular disciplines appearing harder than zoology, botany or ecology. In multivariable analyses, most of these parameters were independent predictors of the hierarchy, even when mathematics and the humanities were included. These results support a "gradualist" view of scientific knowledge, suggesting that the Hierarchy of the Sciences provides the best rational framework to understand disciplines' diversity. A deeper grasp of the relationship between subject matter's complexity and consensus could have profound implications for how we interpret, publish, popularize and administer scientific research.

Botany, traditional uses, phytochemistry and pharmacology of Apocynum venetum L. (Luobuma): A review.

Science.gov (United States)

Xie, Wenyan; Zhang, Xiaoying; Wang, Tian; Hu, Jianjun

2012-05-07

Apocynum venetum L. (Apocynaceae, Luobuma ) has a long history as a Chinese traditional medicine with uses to calm the liver, soothe the nerves, dissipate heat, and promote diuresis. Recently, Luobuma tea has been commercialized as a sedative and anti-aging supplement that has become increasingly popular in North American and East Asian health food markets. The aim of this review is to provide an up-to-date and comprehensive overview of the botany, chemical constituents, traditional uses, pharmacological activities and safety aspects of Apocynum venetum in order to assess its ethnopharmacological use and to explore its therapeutic potentials and future opportunities for research. The accessible literature on Apocynum venetum written in English, Chinese and Japanese were collected and analyzed. The literatures included ancient Chinese herbal classics, pharmacopoeias and articles that included in Pubmed, Web of Science, Google Scholar and Wanfang. Modern pharmacological studies demonstrated that Apocynum venetum possess wide pharmacological activities that include antihypertensive, cardiotonic, hepatoprotective, antioxidant, lipid-lowering, antidepressant and anxiolytic effects, which can be explained by the presence of various flavonoid compounds in this plant. The traditional (Lop Nor region) use of Apocynum venetum with tobacco as an agent to detoxify nicotine may receive interest as a possible therapeutic option to detoxify the body from smoking. Based on animal studies and clinical trials, Apocynum venetum causes no severe side effects, even in a stable daily dosage (50mg/person/day) for more than three years. Apocynum venetum potentially has therapeutic potential in the prevention and treatment for the cardiovascular and neurological diseases, especially for high blood pressure, high cholesterol, neurasthenia, depression and anxiety. Further investigations are needed to explore individual bioactive compounds responsible for these in vitro and in vivo

Full Text Available Since 2002 the Denver Zoological Foundation has produced 28 African hunting dog (Lycaon Pictus puppies in 3 litters (7, 14 and 7 pups from the same dam and sire. Wellness examinations were performed on each puppy. The wellness examinations spanned the range of 6-14 weeks of age. During the wellness examinations, in addition to physical examinations and vaccinations, blood samples for complete blood counts and sera biochemistry were obtained.Weights, morphometric measurements, rectal cultures for enteric pathogens and dental eruption patterns were recorded. Blood samples from each age group were compared with adult values from the Denver Zoo. It was noted that animals from the 14-pup litter were 63.6 % of the mean weight of the two 7-pup litters, but size differences (in, for example, total bodylength were less apparent. Two organisms were recovered from rectal cultures, namely Yersinia enterocolitica (n = 2 and Plesiomonas shigelloides (n = 3. The following deciduous eruption patterns were also noted; at 6 weeks, I1-3, i1-3, C1, c1, P1-2 and p1-2 (n=7 were present, at 9-10 weeks, P3 and p3 (n=21 , and finally at 12-14 weeks, P4 (n = 28.

Kholodny Institute of Botany, National Academy of Science of Ukraine, Kyiv, Ukraine * elena.samolov@uni-rostock.de Biological soil crusts (BSCs) are an association of different microorganisms and soil particles in the top millimeters of the soil. They are formed by algae, cyanobacteria, microfungi, bacteria, bryophytes and lichens in various compositions; together with their by-products they create a micro-ecosystem that performs important ecological functions, e.g. primary production, nitrogen fixation, mineralization and stabilization of soils. These top-soil assemblages are almost unstudied in South America (Büdel et al. 2016). Therefore, our aim is to investigate for the first time biodiversity of the key photosynthetic organisms, green algae and cyanobacteria following a precipitation gradient along the west coast of Chile. We are applying polyphasic approach - a combination of microscopy, culture dependent (16S and 18S rRNA, ITS) and culture independent molecular techniques (NGS). First results, based on culturing and light microscopy, showed high diversity of eukaryotic algae in biocrusts from humid regions, followed by semi-arid regions. Lichen dominated biocrusts from arid regions were characterized by a high diversity of green algae, while cyanobacteria were scarcely present. The functional role of the BSCs in the biogeochemical cycle of phosphorous (P) was evaluated using state of the art analytical methods including 31P-NMR (nuclear magnetic

The wildlife trade poses substantial threats to global biodiversity. China is a significant source of threatened species and also a market for wildlife products. Zoological parks (zoos), which are a popular leisure attraction in China as elsewhere, are increasingly conceptualized as places to educate visitors about both animals and environmental threats more generally. This paper reports on an attempt to inform Chinese zoo visitors about the threats presented by the wildlife trade, and about the opportunity to take personal actions to help protect wildlife. Results from a baseline survey of attitudes among 524 adult visitors to animal exhibits in Chengdu, China showed a high degree of concern about wildlife paired with a lack of confidence about what could be done. A sense of connection to nature, along with a perception of personal efficacy, were the strongest predictors of concern about the wildlife trade. Based in part on these results, an informational exhibit was designed and implemented in two locations in Chengdu. A survey of 533 visitors to assess the impact of the new exhibit showed that connection and perceived efficacy continued to predict concern, and that talking about the exhibit was associated with increased knowledge and concern. Though causality cannot be definitively concluded, results suggest that zoos have the potential to influence attitudes and perceived norms regarding the wildlife trade. By affirming the importance of a feeling of connection, the findings indicate that animal facilities may have an important role in fostering the human relationship to the natural world. © 2018 Wiley Periodicals, Inc.

Defending metropolitan identity through colonial politics: The role of Portuguese naturalists (1870-91).

Science.gov (United States)

Gamito-Marques, Daniel

2018-06-01

This paper explores how João de Andrade Corvo and José Vicente Barbosa du Bocage, two nineteenth-century Portuguese naturalists, were able to reach prominent political positions in their country by means of their work in, respectively, botany and agriculture, and zoology. The authority they derived from their scientific activities and the knowledge they acquired in the process, favored by their proximity to particular political quarters, elevated them to important governmental offices, in the context of which they implemented policies that reinforced Portugal's identity as an imperial nation. The colonial policies and agreements signed by Corvo and Bocage aimed at securing Portuguese colonial territories, which, aside from their economic relevance, constituted a symbol of power that reinforced the sovereignty of a small nation in a Europe dominated by the rule of increasingly vaster and stronger states. In spite of their different scientific careers and personal interests, both naturalists played key roles in Portuguese foreign affairs and colonial negotiations of the late nineteenth century, especially during the Scramble for Africa.

2013-07-30

Polygonum cuspidatum Sieb. et Zucc. (Polygonum cuspidatum), also known as Reynoutria japonica Houtt and Huzhang in China, is a traditional and popular Chinese medicinal herb. Polygonum cuspidatum with a wide spectrum of pharmacological effects has been used for treatment of inflammation, favus, jaundice, scald, and hyperlipemia, etc. The present paper reviews the traditional applications as well as advances in botany, phytochemistry, pharmacodynamics, pharmacokinetics and toxicology of this plant. Finally, the tendency and perspective for future investigation of this plant are discussed, too. A systematic review of literature about Polygonum cuspidatum is carried out using resources including classic books about Chinese herbal medicine, and scientific databases including Pubmed, SciFinder, Scopus, the Web of Science and others. Polygonum cuspidatum is widely distributed in the world and has been used as a traditional medicine for a long history in China. Over 67 compounds including quinones, stilbenes, flavonoids, counmarins and ligans have been isolated and identified from this plant. The root of this plant is used as the effective agent in pre-clinical and clinical practice for regulating lipids, anti-endotoxic shock, anti-infection and anti-inflammation, anti-cancer and other diseases in China and Japan. As an important traditional Chinese medicine, Polygonum cuspidatum has been used for treatment of hyperlipemia, inflammation, infection and cancer, etc. Because there is no enough systemic data about the chemical constituents and their pharmacological effects or toxicities, it is important to investigate the pharmacological effects and molecular mechanisms of this plant based on modern realization of diseases' pathophysiology. Drug target-guided and bioactivity-guided isolation and purification of the chemical constituents from this plant and subsequent evaluation of their pharmacologic effects will promote the development of new drug and make sure which

The Bhutanese Sowa Rigpa medicine (BSM) uses animal parts in the preparation of numerous polyingredient traditional remedies. Our study reports the taxonomical identification of medicinal animals and the description of traditional uses in English medical terminologies. To taxonomically identify the medicinal animals and their derived natural products used as a zootherapeutic agents in BSM. First, the traditional textbooks were reviewed to generate a list of animal products described as ingredients. Second, animal parts that are currently used in Bhutan were identified. Third, the ethnopharmacological uses of each animal ingredients were translated into English medical terminologies by consulting Traditional Physicians, clinical assistants, pharmacognosists, and pharmacists in Bhutan. Fourth, the animal parts were taxonomically identified and their Latin names were confirmed by crosschecking them with online animal databases and relevant scientific literature. The study found 73 natural products belonging to 29 categories derived from 45 medicinal animals (36 vertebrates and 9 invertebrates), comprising of 9 taxonomic categories and 30 zoological families. Out of 116 formulations currently produced, 87 of them contain one or more extracts and products obtained from 13 medicinal animals to treat more than 124 traditionally classified illnesses. Only five animal ingredients were found available in Bhutan and rest of the animal parts are being imported from India. Out of 73 natural products described in the traditional textbooks, only 13 of them (some omitted and few substituted by plants) are currently included in 87 formulations of BSM.

Dinoflagellate cyst abundance is positively correlated to sediment organic carbon in Sydney Harbour and Botany Bay, NSW, Australia.

2018-02-01

There is growing public concern about the global expansion of harmful algal bloom species (HABs), with dinoflagellate microalgae comprising the major portion of the harmful taxa. These motile, unicellular organisms have a lifecycle involving sexual reproduction and resting cyst formation whereby cysts can germinate from sediments and 'seed' planktonic populations. Thus, investigation of dinoflagellate cyst (dinocyst) distribution in sediments can provide significant insights into HAB dynamics and contribute to indices of habitat quality. Species composition and abundance of dinocysts in relation to sediment characteristics were studied at 18 stations in two densely populated temperate Australian estuaries, Sydney Harbour (Parramatta River/Port Jackson; PS) and Botany Bay (including Georges River; GB). Eighteen dinocyst taxa were identified, dominated by Protoceratium reticulatum and Gonyaulax sp.1 in the PS estuary, together with Archaeperidinium minutum and Gonyaulax sp.1 in the GB estuary. Cysts of Alexandrium catenella, which is one of the causative species of paralytic shellfish poisoning (PSP), were also detected in both estuaries. Out of the measured sediment characteristics (TOC, Cd, Cr, Cu, Fe, Pb, Mn, Ni, Zn and polycyclic aromatic hydrocarbons), TOC was the parameter explaining most of the variation in dinocyst assemblages and was positively correlated to most of the heavy metals. Given the significant relationship between sediment TOC and dinocyst abundance and heavy metal concentrations, this study suggests that sediment TOC could be broadly used in risk management for potential development of algal blooms and sediment contamination in these estuaries.

Devriesea agamarum is a Gram-positive bacterium that was first described in 2008 as a causative agent of disease in lizards. Until today, reports from several countries reported the presence of this bacterium in various lizard species, which suggests a wide distribution among lizard collections. Pathologic lesions ranged from proliferative dermatitis and cheilitis to abscesses in multiple organs and septicemia in single animals, as well as entire groups. Until now, disease caused by D. agamarum has been reported in several lizard species. Because the bacterium is only identified by 16S rRNA sequencing and no commercially available identification systems contain the agent in their database, it may be underdiagnosed. This report describes a series of fatal devrieseasis in plumed basilisks (Basiliscus plumifrons) and Chinese water dragons (Physignathus cocincinus) from a zoologic collection and extends the range of susceptible species. In 3 mo, five animals died with pyogranulomatous lesions in the subcutis, the coelomic cavity, or multiple organs. In all cases, diffuse swelling or focal skin elevations of different body parts were observed. Devriesea agamarum could be isolated from lesions in all animals. A subsequent clinical survey of the lizard collection including bacteriologic investigation of oral cavity swabs indicated that bearded dragons (Pogona vitticeps) were carriers of D. agamarum, which suggests that this species could be a source of infection with this pathogen.

Full Text Available Los museos de Botánica, Mineralogía y Zoología de la Facultad de Ciencias Físico-Matemáticas se formaron en el marco de un fenómeno de alcance mundial, definido por ciertos autores como 'museum movement', durante un período en el cual los fundamentos de ese movimiento se encontraban en un proceso de reelaboración. En este sentido, el propósito del trabajo es analizar la etapa constitutiva de los museos de historia natural en un espacio periférico - Córdoba a fines del siglo XIX - con el fin de conocer parcialmente ese proceso de transición. La estrategia definida puso a las colecciones en el centro del análisis para saber cómo se formaron y con qué finalidad. También se abordaron otros dos aspectos de relevancia: la dotación de recursos humanos y de fondos para esas instituciones.The museums of Botany, Mineralogy and Zoology of the Facultad de Ciencias Físico-Matemáticas were created along with a world wide phenomenon, defined by some authors as the "museum movement," in a time the basics of this movement were being restructured. Thus, this work intends to go over the building stage of the natural history museums in a peripheral domain - Cordoba by the end of the 19th century - in order to partially understand this transition process. The strategy is to analyze the collections and find out how and why they were gathered. Two other aspects are also relevant: the human resources and the funds these institutions were granted.

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

Science.gov (United States)

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?

Cytogenetic Examination of South American Tapirs, Tapirus Terrestris (Perissodactyla, Tapiridae, from the Wroclaw Zoological Garden

2015-12-01

Full Text Available Cytogenetic Examination of South American Tapirs, Tapirus terrestris (Perissodactyla, Tapiridae from the Wroclaw Zoological Garden. Kosowska, B., Strzała, T., Moska, M., Ratajszczak, R., Dobosz, T. - Seven lowland tapirs (Tapirus terrestris from Wrocław ZOO (three females and four males, differing from each other with exterior and sexual behaviour were verified with cytogenetic analysis in order to check their taxonomic status. Cytogenetic analysis was done using two alternative methods of blood collection: 1 conventionally with venepuncture, and 2 with blood sucking bugs from the Reduviidae family. Lymphocytes capable of growing were obtained only with conventional method of blood sampling. Karyotypes and karyograms of all analyzed tapirs were created using classical cytogenetic methods of chromosomes staining. All possessed karyograms had diploid chromosome number equal 80 (2n = 80. Homologous chromosomes did not differ between each other with quantity, size, centromeres location, length of arms, G bands and all were classified as proper karyograms of Tapirus terrestris species representatives. The X chromosomes as well as the first pair of chromosomes (both metacentric, were the largest among all analyzed, respectively. All remaining 38 pairs of chromosomes were acrocentric with Y chromosome as the smallest one (in males’ karyograms. Blood collected with blood sucking bugs proved to be unsuitable for cell culture. None of the seven established cultures was effective as lymphocytes obtained with this method did not show growth potential in prepared media. Thus, blood collected from the tapirs via Dipetalogaster maxima species did not show usefulness for cytogenetic studies due to the inability of cells to proliferation, even after a relatively short period of time elapsed since the blood sampling (1 to 2 hours.

Understanding the basic biology underlying the flavor world of children

Directory of Open Access Journals (Sweden)

Julie A. MENNELLA, Alison K. VENTURA

2010-12-01

Full Text Available Health organizations worldwide recommend that adults and children minimize intakes of excess energy and salty, sweet, and fatty foods (all of which are highly preferred tastes and eat diets richer in whole grains, low- and non- fat dairy products, legumes, fish, lean meat, fruits, and vegetables (many of which taste bitter. Despite such recommendations and the well-established benefits of these foods to human health, adults are not complying, nor are their children. A primary reason for this difficulty is the remarkably potent rewarding properties of the tastes and flavors of foods high in sweetness, saltiness, and fatness. While we cannot easily change children’s basic ingrained biology of liking sweets and avoiding bitterness, we can modulate their flavor preferences by providing early exposure, starting in utero, to a wide variety of flavors within healthy foods, such as fruits, vegetables, and whole grains. Because the flavors of foods mothers eat during pregnancy and lactation also flavor amniotic fluid and breast milk and become preferred by infants, pregnant and lactating women should widen their food choices to include as many flavorful and healthy foods as possible. These experiences, combined with repeated exposure to nutritious foods and flavor variety during the weaning period and beyond, should maximize the chances that children will select and enjoy a healthier diet [Current Zoology 56 (6: 834–841, 2010].

Boveri's research at the Zoological Station Naples: Rediscovery of his original microscope slides at the University of Würzburg.

2018-02-14

Eric Davidson once wrote about Theodor Boveri: "From his own researches, and perhaps most important, his generalized interpretations, derive the paradigms that underlie modern inquiries into the genomic basis of embryogenesis" (Davidson, 1985). As luck would have it, the "primary data" of Boveri's experimental work, namely the microscope slides prepared by him and his wife Marcella during several stays at the Zoological Station in Naples (1901/02, 1911/12 and 1914), have survived at the University of Würzburg. More than 600 slides exist and despite their age they are in a surprisingly good condition. The slides are labelled and dated in Boveri's handwriting and thus can be assigned to his published experimental work on sea urchin development. The results allowed Boveri to unravel the role of the cell nucleus and its chromosomes in development and inheritance. Here, I present an overview of the slides in the context of Boveri's work along with photographic images of selected specimens taken from the original slides. It is planned to examine the slides in more detail, take high-resolution focal image series of significant specimens and make them online available. Copyright © 2018 The Author.

Recent introduction of an allodapine bee into Fiji: A new model system for understanding biological invasions by pollinators.

Science.gov (United States)

Groom, Scott V C; Tuiwawa, Marika V; Stevens, Mark I; Schwarz, Michael P

2015-08-01

Morphology-based studies have suggested a very depauperate bee fauna for islands in the South West Pacific, and recent genetic studies since have indicated an even smaller endemic fauna with many bee species in this region resulting from human-aided dispersal. These introduced species have the potential to both disrupt native pollinator suites as well as augment crop pollination, but for most species the timings of introduction are unknown. We examined the distribution and nesting biology of the long-tongued bee Braunsapis puangensis that was first recorded from Fiji in 2007. This bee has now become widespread in Fiji and both its local abundance and geographical range are likely to increase dramatically. The impacts of this invasion are potentially enormous for agriculture and native ecosystems, but they also provide opportunities for understanding how social insect species adapt to new environments. We outline the major issues associated with this recent invasion and argue that a long-term monitoring study is needed. © 2014 Institute of Zoology, Chinese Academy of Sciences.

Warburgia: a comprehensive review of the botany, traditional uses and phytochemistry.

Science.gov (United States)

Leonard, Carmen M; Viljoen, Alvaro M

2015-05-13

The genus Warburgia (Canellaceae) is represented by several medicinal trees found exclusively on the African continent. Traditionally, extracts and products produced from Warburgia species are regarded as important natural African antibiotics and have been used extensively as part of traditional healing practices for the treatment of fungal, bacterial and protozoal infections in both humans and animals. We here aim to collate and review the fragmented information on the ethnobotany, phytochemistry and biological activities of ethnomedicinally important Warburgia species and present recommendations for future research. Peer-reviewed articles using "Warburgia" as search term ("all fields") were retrieved from Scopus, ScienceDirect, SciFinder and Google Scholar with no specific time frame set for the search. In addition, various books were consulted that contained botanical and ethnopharmacological information. The ethnopharmacology, phytochemistry and biological activity of Warburgia are reviewed. Most of the biological activities are attributed to the drimane sesquiterpenoids, including polygodial, warburganal, muzigadial, mukaadial and ugandensial, flavonoids and miscellaneous compounds present in the various species. In addition to anti-infective properties, Warburgia extracts are also used to treat a wide range of ailments, including stomach aches, fever and headaches, which may also be a manifestation of infections. The need to record anecdotal evidence is emphasised and conservation efforts are highlighted to contribute to the protection and preservation of one of Africa's most coveted botanical resources.

Polygonum multiflorum Thunb., which is known as Heshouwu ( in Chinese) in China. It is traditionally valued and reported for hair-blacking, liver and kidney-tonifying and anti-aging effects as well as low toxicity. The aim of this review is to provide comprehensive information on the botany, traditional uses, phytochemistry, pharmacological research and toxicology of Polygonum multiflorum, based on the scientific literature. Moreover, trends and perspectives for future investigation of this plant are discussed. It will build up a new foundation for further study on Polygonum multiflorum. A systematic review of the literature on Polygonum multiflorum was performed using several resources, including classic books on Chinese herbal medicine and various scientific databases, such as PubMed, SciFinder, the Web of Science, Science Direct, China Knowledge Resource Integrated (CNKI). Polygonum multiflorum is widely distributed throughout the world and has been used as a traditional medicine for centuries in China. The ethnomedical uses of Polygonum multiflorum have been recorded in many provinces of China and Japan for nine species of adulterants in six families. More than 100 chemical compounds have been isolated from this plant, and the major components have been determined to be stilbenes, quinones, flavonoids and others. Crude extracts and pure compounds of this plant are used as effective agents in pre-clinical and clinical practice due to their anti-aging, anti-hyperlipidaemia, anti-cancer and anti-inflammatory effects and to promote immunomodulation, neuroprotection, and the curing of other diseases. However, these extracts can also lead to hepatotoxicity, nephrotoxicity and embryonic toxicity. Pharmacokinetic studies have demonstrated that the main components of Polygonum multiflorum, such as 2,3,5,4'-tetrahydroxystilbene-2-O-β-d-glucopyranoside and emodin are distributed among many organs and tissues. Therapeutic potential of Polygonum multiflorum has been

Full Text Available Abstract Canine heartworm (cHW disease is now recognised as potential cause of serious disease in cats and other felids, especially in endemic areas. In March 2009, a 23-years-old male African leopard (Panthera pardus pardus housed in a zoological park located in the Province of Padova (Veneto Region, a cHW endemic area of the north-eastern Italy, died and was immediately necropsied. A cloth completely occluding the pyloric lumen was considered the presumptive cause of death. During necropsy, six nematodes (4 males and 2 females were found within the right ventricle of the heart and the pulmonary artery. Diagnosis of HW (Dirofilaria immitis infection was carried out by morphological features of adult worms and microfilariae, and then confirmed by detection of circulating HW antigens using a commercial SNAP kit (IDEXX Laboratories inc., USA. D. immitis infection was also confirmed by PCR amplification of the 5S ribosomal spacer region, performed on worm fragments and microfilaraemic blood samples obtained from the right ventricle of the heart. A glomerulonephritis of immuno-mediated origin and most likely associated with the HW infection is also reported. HW chemoprophylaxis and annual serological testing on wild felids housed outdoors in endemic cHW disease areas are recommended. This is the first diagnosis of D. immitis infection in an exotic felid in Italy.

A complete catalogue is provided for the type specimens of anguid, dibamid, scincid and varanid lizards in the herpetological collection of the Zoological Institute, Russian Academy of Sciences, St. Petersburg, Russia (ZISP), as of January 2017. The collection contains a total of 170 type specimens, representing 50 taxa in the four lizard families under consideration. Thirty-one of these taxa are regarded currently as valid. The types of four taxa (one holotype, one lectotype and two paralectotypes) could not be located in the ZISP collections in January 2017. A majority of the types are skinks (43 taxa, 155 types), many of which were described by the late Ilya Darevsky (1924-2009).

The Results of Development of the Project ZOOINT and its Future Perspectives

Smirnov, I. S.; Lobanov, A. L.; Alimov, A. F.; Medvedev, S. G.; Golikov, A. A.

The work on a computerization of main processes of accumulation and analysis of the collection, expert and literary data on a systematics and faunistics of various taxa of animal (a basis of studying of a biological diversity) was started in the Zoological Institute in 1987. In 1991 the idea of creating of the software package, ZOOlogical INTegrated system (ZOOINT) was born. ZOOINT could provide a loading operation about collections and simultaneously would allow to analyze the accumulated data with the help of various queries. During execution, the project ZOOINT was transformed slightly and has given results a little bit distinguished from planned earlier, but even more valuable. In the Internet the site about the information retrieval system (IRS) ZOOINT was built also ( ZOOINT ). The implementation of remote access to the taxonomic information, with possibility to work with databases (DB) of the IRS ZOOINT in the on-line mode was scheduled. It has required not only innovation of computer park of the developers and users, but also mastering of new software: language HTML, operating system of Windows NT, and technology of Active Server Pages (ASP). One of the serious problems of creating of databases and the IRS on zoology is the problem of representation of hierarchical classification. Building the classifiers, specialized standard taxonomic databases, which have obtained the name ZOOCOD solved this problem. The lately magnified number of attempts of creating of taxonomic electronic lists, tables and DB has required development of some primary rules of unification of zoological systematic databases. These rules assume their application in institutes of the biological profile, in which the processes of a computerization are very slowly, and the building of databases is in the most rudimentary state. These some positions and the standards of construction of biological (taxonomic) databases should facilitate dialogue of the biologists, application in the near

Full Text Available Central America is recognized as a mega diverse “hot-spot” and one of its smaller countries, Costa Rica, as one of the world’s leaders in the study and conservation of tropical biodiversity. For this study, inspired by the 60th anniversary of the journal Revista de Biología Tropical, we tabulated all the scientific production on Costa Rican biodiversity published in Revista de Biología Tropical between 2000 and 2010. Most articles are zoological (62% and 67% of authors had only one publication in the jounal within that period. A 54% of articles were published in English and 46% in Spanish. A 41% of articles were written in collaboration among Costa Rican institutions and 36% in collaboration with foreign institutions. The Collaboration Index was 2.53 signatures per article. Visibility in American sources was 56% in Google Scholar and 42.66% in the Web of Science, but the real visibility and impact are unknown because these sources exclude the majority of tropical journals. Revista de Biología Tropical is the main output channel for Costa Rican biology and despite its small size, Costa Rica occupies the 10th. place in productivity among Latin American countries, with productivity and impact levels that compare favorably with larger countries such as Brazil, Mexico, Argentina and Chile.América Central es reconocida como región mega- diversa y uno de sus países más pequeños, Costa Rica, se encuentra entre los líderes mundiales en el estudio y conservación de la biodiversidad tropical.

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

In memoriam : Miriam Dorothy (Posner) Finkel (1916-1999)

International Nuclear Information System (INIS)

Reilly, C.A.

2000-01-01

Miriam P. Finkel, pioneer radiobiologist, passed away on August 20, 1999, at her home in Tucson, AZ. She was born on January 22, 1916, in Chicago to Russian immigrants. She spent much of her youth in Davenport, IA. She returned to Chicago for her college education, and received a B.S. in zoology in 1938 from the University of Chicago. While continuing her formal education in zoology, Miriam served as a laboratory instructor at Wilson Junior College. She received her Ph.D. in 1944 from the University of Chicago. She began her scientific career at the dawning of the nuclear age and seized upon the scientific opportunity present in the new field of radiobiology to be a life-long contributor to the understanding of the biological effects of radiation. Her technical insights and discoveries helped form the foundation for many of the health standards (i.e. permissible levels of internal radionuclide exposure) in use today. She also made a significant contribution to the field of molecular biology. Her isolation of a murine osteogenic sarcoma virus, the Finkel-Biskis-Jenkins or FBJ virus, led to fundamental discoveries in viral-induced tumors and ultimately provided the now universally used molecular biological tool, the FOS gene.

Introduction to the Special Issue: Beyond traits: integrating behaviour into plant ecology and biology.

Science.gov (United States)

Cahill, James F

2015-10-26

The way that plants are conceptualized in the context of ecological understanding is changing. In one direction, a reductionist school is pulling plants apart into a list of measured 'traits', from which ecological function and outcomes of species interactions may be inferred. This special issue offers an alternative, and more holistic, view: that the ecological functions performed by a plant will be a consequence not only of their complement of traits but also of the ways in which their component parts are used in response to environmental and social conditions. This is the realm of behavioural ecology, a field that has greatly advanced our understanding of animal biology, ecology and evolution. Included in this special issue are 10 articles focussing not on the tried and true metaphor that plant growth is similar to animal movement, but instead on how application of principles from animal behaviour can improve our ability to understand plant biology and ecology. The goals are not to draw false parallels, nor to anthropomorphize plant biology, but instead to demonstrate how existing and robust theory based on fundamental principles can provide novel understanding for plants. Key to this approach is the recognition that behaviour and intelligence are not the same. Many organisms display complex behaviours despite a lack of cognition (as it is traditionally understood) or any hint of a nervous system. The applicability of behavioural concepts to plants is further enhanced with the realization that all organisms face the same harsh forces of natural selection in the context of finding resources, mates and coping with neighbours. As these ecological realities are often highly variable in space and time, it is not surprising that all organisms-even plants-exhibit complex behaviours to handle this variability. The articles included here address diverse topics in behavioural ecology, as applied to plants: general conceptual understanding, plant nutrient foraging, root

The colony of urban stray cats living in the Rio de Janeiro zoological garden was studied in order to develop a population and health control program. As many cats as possible were captured during two months (47 animals) and were classified according to gender, age, weight and coat markings. They were submitted to a general health evaluation, examined for the presence of ectoparasites and sent to a surgical neutering program. All animals had a blood sample drawn for CBC, platelet count, heartworm and retroviruses detection. Capillary blood smears were made for hemoparasites detection. Coat marking and colors were tabby (59.7%), followed by solid black (17%); torbie (10.6%); bicolor (10.6%) and harlequin (2.1%). The only ectoparasites found were fleas, which infested 28% of the animals. The hemoparasites found were Haemobartonella felis (38%) and piroplasmas that could not be differentiated between Cytauxzoon spp. and Babesia spp. (47%). No cat was found infected by Dirofilaria immitis or FeLV (Feline Leukemia Virus), although FIV (Feline Immunodeficiency Virus) antibodies could be detected (21%). There was no correlation between hemoparasites and FIV infections. The estimated total cat population (mark-recapture method) was 59; 68% female and 32% male, suggesting that a neutering program is in fact needed.

Plant roots can contribute significantly to the stability of steep slopes. They can anchor through the soil mass into fractures in bedrock, can cross zones of weakness to more stable soil, and can provide interlocking long fibrous binders within a weak soil mass. In deep soil, anchoring to bedrock becomes negligible, and lateral reinforcement predominates

Areca catechu L. (Arecaceae), widely distributed in South and Southeast Asia, is a popular traditional herbal medicine that can be chewed for the purpose of dispersing accumulated fluid in the abdominal cavity and killing worms. The present paper aims to provide an up-to-date review on the traditional uses and advances in the botany, phytochemistry, pharmacology and toxicology of this plant. Furthermore, the possible trends and a perspective for future research of this plant are also discussed. A literature search was performed on A. catechu based on classic books of herbal medicine, PhD. and MSc. dissertations, government reports, the state and local drug standards, scientific databases including Pubmed, SciFinder, Scopus, the Web of Science, Google Scholar, and others. Various types of information regarding this plant are discussed in corresponding parts of this paper. In addition, perspectives for possible future studies of A. catechu are discussed. The seeds of A. catechu (areca nut) have been widely used in clinical practice in China, India and other South and Southeast Asian Countries. Currently, over 59 compounds have been isolated and identified from A. catechu, including alkaloids, tannins, flavones, triterpenes, steroids, and fatty acids. The extracts and compounds isolated from A. catechu have many pharmacological activities. These include antiparasitic effects, anti-depressive effects, anti-fatigue effects, antioxidant effects, antibacterial and antifungal effects, antihypertensive effects, anti-inflammatory and analgesic effects, anti-allergic effects, the promotion of digestive functions, suppression of platelet aggregation, regulatory effects on blood glucose and lipids, etc. Although arecoline is the primary active constituent of A. catechu, it is also the primary toxic compound. The main toxicities of arecoline are the promotion of oral submucosal fibrosis (OSF) and cytotoxic effects on normal human cells, which involve inducing apoptosis. As an

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. © 2014 WILEY-VCH Verlag GmbH & Co.

Rice, MaryJoe K; Ruder, Warren C

2014-01-01

Synthetic biology is a new discipline that combines science and engineering approaches to precisely control biological networks. These signaling networks are especially important in fields such as biomedicine and biochemical engineering. Additionally, biological networks can also be critical to the production of naturally occurring biological nanomaterials, and as a result, synthetic biology holds tremendous potential in creating new materials. This review introduces the field of synthetic biology, discusses how biological systems naturally produce materials, and then presents examples and strategies for incorporating synthetic biology approaches in the development of new materials. In particular, strategies for using synthetic biology to produce both organic and inorganic nanomaterials are discussed. Ultimately, synthetic biology holds the potential to dramatically impact biological materials science with significant potential applications in medical systems. (review)

Collection and collation: theory and practice of Linnaean botany.

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.

Citri Reticulatae Pericarpium (Rutaceae, CRP), commonly called as Chenpi () in Chinese, is most frequently used as a qi-regulating drug in thousands of Chinese medicine prescriptions. CRP is found mainly in major citrus-producing areas such as the Guangdong, Guangxi, Sichuan, Fujian, and Zhejiang Provinces of China. Since thousands of years in China, CRP has been used widely in clinical practice to treat nausea, vomiting, indigestion, anepithymia, diarrhea, cough, expectoration, and so on. Currently, CRP is listed in the Pharmacopoeia of the People's Republic of China. The present paper reviews the botany, ethnopharmacology, phytochemistry, pharmacology, quality control, and toxicology of CRP. Information on CRP was gathered from various sources including the books on traditional Chinese herbal medicine; scientific databases including Elsevier, PubMed, and ScienceDirect; Baidu Scholar; CNKI; and others and from different professional websites. Approximately 140 chemical compounds have been isolated and identified from CRP. Among them, volatile oils and flavonoids are generally considered as the main bioactive and characteristic ingredients. CRP possesses wide pharmacological effects such as having a beneficial effect on the cardiovascular, digestive, and respiratory systems, antitumor, antioxidant, and anti-inflammatory properties; and a protective effect on the liver and nerve. Moreover, hesperidin is chosen as an indicator in the quantitative determination of CRP, and the quantity of aflatoxin in CRP must not exceed the standard limit mentioned in the pharmacopoeia. In brief, CRP has a warming nature, and hence, it can be used in harmony with a lot of medicines. CRP not only exhibits its effects individually but also aids other medicines exhibit a better effect. CRP can be consumed with tea, food, alcohol, and medicine. Irrespective of the form it is being consumed, CRP not only shows a synergistic effect but also has strengths on its own. Modern pharmacological

Many Chinese medicinal materials (CMMs) have changed over centuries of use, particularly in terms of their botanical identity and processing methods. In some cases, these changes have important implications for safety and efficacy in modern clinical practice. As most previous research has focused on clarifying the evolution of CMMs by analyzing traditional Chinese materia medica ("bencao") literature, assessments of historical collections are needed to validate these conclusions with material evidence. Historical collections of Chinese medicines reveal the market materials in circulation at a given moment in time, and represent an underexploited resource for analyzing the evolution of Chinese herbal medicines. This study compares specimens from a rare collection of CMMs from the 1920s with contemporary market materials; by highlighting examples of changes in botanical identity and processing that remain relevant for safe clinical practice in the modern era, this work aims to stimulate further research into previously unexplored historical collections of Chinese medicines. 620 specimens of CMMs that were collected from Chinese pharmacies in the Malay peninsula in the 1920s were examined macroscopically and compared with current pharmacopoeia specifications and authentic contemporary samples. These historical specimens, which are stored in the UK in the Economic Botany Collections (EBC) of Royal Botanic Gardens Kew, were morphologically examined, photographed, and compared to authentic CMMs stored at the Bank of China (Hong Kong) Chinese Medicines Center at Hong Kong Baptist University, as well as authentic herbarium-vouchered specimens from the Leon Collection (LC) at the Kew EBC. Case studies were selected to illustrate examples of historical changes in botanical identity, used plant parts, and processing methods. This investigation confirmed that confusion due to shared common names and regional variations in the botanical identity of certain CMMs has been a

One of the many areas of research initiated by Swaminathan at the Botany Division of the Indian Agricultural Research Institute, New Delhi was radiation cytogenetics, which involves study of induced chromosomal aberrations. These studies had impact not only on elucidating basic mechanisms involved in the formation of chromosomal aberrations, but also several practical applications related to human health. In this review, we briefly summarize two applications, namely biological dosimetry following radiation accidents and safety of irradiated food material. (author)
