This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Headwater streams are common features of forested landscape and provide critical resources to near-stream riparian forests and downstream aquatic habitat. In many small streams in the southern Appalachians, often narrow and heavily shaded, these systems are almost entirely dependent on external input of nutrients. The volume and quality of nutrients available to headwater ecosystems varies through space and time, depending on the species of trees present in riparian forests, the time of year, and the rate of litter-processing by invertebrates. Additionally, nutrients are not distributed uniformly through aquatic ecosystems, and may be moved or aggregated by both physical and biological processes. Despite the perceived greater reliance on allochthonous input, there has been little work to identify how wildlife inhabiting smaller streams are facilitating stream nutrient dynamics both within streams and riparian systems. To increase our understanding of the role of animals in headwater streams, my research investigates the patterns of density, biomass, foraging, and excretion in the Black-bellied salamander (Desmognathus quadramaculatus), the largest, most-aquatic species of salamander occurring in fishless headwaters of the southern Appalachians. Desmognathus quadramaculatus forage both within and directly around streams, spending significant amounts of non-foraging time in stream banks or under partially submerged cover objects. Additionally, D. quadramaculatus have a 3-year larval period in this region and require permanent aquatic habitat for larval development.

Download or read book Threatened Amphibians of the World written by S. N. Stuart and published by . This book was released on 2008 with total page 784 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Amphibians are facing an extinction crisis, but getting to the facts has been difficult. "Threatened Amphibians of the World" is a visual journey through the first-ever comprehensive assessment of the conservation status of the world's 6,000 known species of frogs, toads, salamanders, and caecilians. All 1,900 species known to be threatened with extinction are covered, including a description of threats to each species and an evaluation of conservation measures in place or needed. Each entry includes a photograph or illustration of the species where available, a distribution map, and detailed information on range, population and habitat and ecology. Introductory chapters present a detailed analysis of the results, complemented by a series of short essays written by many of the world's leading herpetologists. Appendices include annoted lists of lower risk species and a country-by-country listing of threatened amphibians."--pub. desc.

Download or read book Freshwater Biodiversity written by David Dudgeon and published by Cambridge University Press. This book was released on 2020-05-21 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

Download or read book Ecology of Amphibian Microbial Symbioses written by Eria A. Rebollar and published by Frontiers Media SA. This book was released on 2019-08-02 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of amphibian microbial ecology has greatly advanced in recent years. The work published to date has shown that amphibian skin bacterial communities can be influenced by host species, host life-history stage, environmental conditions, surrounding bacterial communities that serve as reservoirs and external biotic agents such as pathogens. As the ecology of amphibian-microbial symbiosis is a relatively new field, there are still many unanswered questions. The aim of this Research Topic is to highlight recent research on amphibian microbiomes that addresses relevant questions on the ecology of amphibian-microbe interactions. The publications gathered in this Research Topic have expanded our knowledge on the role of microbial symbionts of amphibians and have revealed novel insights that can direct the next set of research questions. We suggest that soon the field will move from the basic (and necessary) descriptions of microbial communities to more experimental approaches that include the use of omics methods and a variety of novel analytic and multivariate approaches. In addition to providing more insights into the microbial and disease ecology of amphibians, these studies may lead to effective ways to manipulate the microbiome to achieve protection from diseases, such as chytridiomycosis.

Download or read book The Eponym Dictionary of Amphibians written by Bo Beolens and published by Pelagic Publishing. This book was released on 2013-04-22 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: New species of animal and plant are being discovered all the time. When this happens, the new species has to be given a scientific, Latin name in addition to any common, vernacular name. In either case the species may be named after a person, often the discoverer but sometimes an individual they wished to honour or perhaps were staying with at the time the discovery was made. Species names related to a person are ‘eponyms’. Many scientific names are allusive, esoteric and even humorous, so an eponym dictionary is a valuable resource for anyone, amateur or professional, who wants to decipher the meaning and glimpse the history of a species name. Sometimes a name refers not to a person but to a fictional character or mythological figure. The Forest Stubfoot Toad Atelopus farci is named after the FARC, a Colombian guerrilla army who found refuge in the toad’s habitat and thereby, it is claimed, protected it. Hoipollo's Bubble-nest Frog Pseudophilautus hoipolloi was named after the Greek for ‘the many’, but someone assumed the reference was to a Dr Hoipollo. Meanwhile, the man who has everything will never refuse an eponym: Sting's Treefrog Dendropsophus stingi is named after the rock musician, in honour of his ‘commitment and efforts to save the rainforest’. Following the success of their Eponym Dictionary of Reptiles, the authors have joined forces to give amphibians a similar treatment. They have tracked down 1,609 honoured individuals and composed for each a brief, pithy biography. In some cases these are a reminder of the courage of scientists whose dedicated research in remote locations exposed them to disease and even violent death. The eponym ensures that their memory will survive, aided by reference works such as this highly readable dictionary. Altogether 2,668 amphibians are listed.
