Download or read book The Effect of Native and Non native Fish on Amphibian Populations in Northeast Washington written by Liana M. Aker and published by . This book was released on 1998 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Researchers are currently investigating reasons behind worldwide amphibian declines and extinction. Habitat destruction and disturbance and the widespread introduction of non-native amphibian and fish species are considered as two major causes of these problems. I investigated the effects of introduced non-native fish on native, pond- breeding amphibians in northeast Washington. Amphibian population data was collected at eleven sites with no fish, nine sites with native fish and twelve non-native fish sites using live trapping techniques and shoreline surveys. Results indicate that non-native fish have a profound negative effect on both amphibian species diversity and abundance. The average number of amphibian species per site was significantly lower in Non-native Fish sites (.58 species/site) than in No-Fish sites (2.0 species/site) and Native Fish sites (1 .67 species/site). The average number of individual amphibians per trap among the three treatments was 0.14 individuals in Non-native Fish sites, 4.61 individuals in No- Fish sights and 1.05 individuals in Native Fish sites. Non-native fish were inadvertently caught in amphibian larvae traps in ten of the twelve Non-native Fish study sites indicating that non-native fish are present in amphibian habitat. No fish were recovered from larvae traps in Native Fish sites. I suggest that managers consider the negative effect introductions of non-native fish may have on native amphibian abundance and species diversity"--Document.

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 Brown Trout written by Javier Lobón-Cerviá and published by John Wiley & Sons. This book was released on 2017-12-18 with total page 821 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brown Trout: Biology, Ecology and Management A comprehensive guide to the most current research, history, genetics and ecology of the brown trout including challenging environmental problems The brown trout is an iconic species across its natural European distribution and has been introduced throughout the World. Brown Trout offers a comprehensive review of the scientific information and current research on this major fish species. While the brown trout is the most sought species by anglers, its introduction to various waters around the world is causing serious environmental problems. At the same time, introduction of exogenous brown trout lineages threats conservation of native gene pools of populations in many regions. The authors summarize the important aspects of the brown trout’s life history and ecology and focus on the impact caused by the species. The text explores potential management strategies in order to maintain numerous damaged populations within its natural distributional range and to ameliorate its impacts in exotic environments. The authors include information on a wide-range of topics such as recent updates in population genetics, evolutionary history, reproductive traits and early ontogeny, life history plasticity in anadromous brown trout and life history of the adfluvial brown trout and much more. This vital resource: Contains the latest research on the biology and ecology of brown trout Includes information on phylogeography, genetics, population dynamics and stock management Spotlights the brown trout’s introduction to regions around the world and the serious environmental impacts Offers a comprehensive review of conservation and management techniques Written for salmonid scientists and researchers, fishery and environmental managers, and students of population genetics, ecology and population dynamics, Brown Trout explores the most recent findings on the history, ecology and sustainability of this much-researched species.
Download or read book Biological Invasions and Global Insect Decline written by Jonatan Rodríguez and published by Elsevier. This book was released on 2023-09-26 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological Invasions and Global Insect Decline offers the most updated knowledge on how invasive alien species affect insect diversity worldwide. The book provides ongoing research and the most relevant information, covering the main aspects of the impact of biological invasions as well as future insights on mitigation and consequences. It discusses how the introduction of all kinds of organisms, from bacteria and plants to vertebrates, affect current declines in insect diversity. The latter portion of the book delves into existent and future monitoring and management programs, including citizen science and regenerative ecology as socio-ecological solutions to combat these threats. Written and edited by international experts on invasion ecology and insect conservation, this book explores the role of global change and the introduction of invasive species in altering the structure of habitats and how this induces a global insect decline. This will be a valuable resource for entomologists, invasion biologists and other researchers in biodiversity conservation, as well as practitioners and stakeholders concerned about problematic invasive alien species and insect population decline. Offers a concise vision of one of the main causes of insect extinctions in the Anthropocene Discusses community ecology, insect conservation, species interactions, restoration ecology Led by a team of editors whose expertise includes invasive alien species, invasion ecology, insect species diversity, and species conservation
Download or read book Extinction in Our Times written by James P. Collins and published by Oxford University Press. This book was released on 2009-07-07 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: For over 350 million years, thousands of species of amphibians have lived on earth, but since the 1990s they have been disappearing at an alarming rate, in many cases quite suddenly and mysteriously. What is causing these extinctions? What role do human actions play in them? What do they tell us about the overall state of biodiversity on the planet? In Extinction in Our Times, James Collins and Martha Crump explore these pressing questions and many others as they document the first modern extinction event across an entire vertebrate class, using global examples that range from the Sierra Nevada of California to the rainforests of Costa Rica and the Mediterranean coast of North Africa. Joining scientific rigor and vivid storytelling, this book is the first to use amphibian decline as a lens through which to see more clearly the larger story of climate change, conservation of biodiversity, and a host of profoundly important ecological, evolutionary, ethical, philosophical, and sociological issues.

Available in PDF, EPUB and Kindle. Book excerpt: Amphibian Conservation is the fourth in the series of Synopses of Conservation Evidence, linked to the online resource www.ConservationEvidence.com. This synopsis is part of the Conservation Evidence project and provides a useful resource for conservationists. It forms part of a series designed to promote a more evidence-based approach to biodiversity conservation. Others in the series include bee, bird, farmland and bat conservation and many others are in preparation. Approximately 32% of the 7,164+ amphibian species are currently threatened with extinction and at least 43% of species are declining. Despite this, until recently amphibians and their conservation had received little attention. Although work is now being carried out to conserve many species, often it is not adequately documented. This book brings together and summarises the available scientific evidence and experience relevant to the practical conservation of amphibians. The authors consulted an international group of amphibian experts and conservationists to produce a thorough summary of what is known, or not known, about the effectiveness of amphibian conservation actions across the world. "The book is packed with literature summaries and citations; a veritable information goldmine for graduate students and researchers. It also admirably provides decision makers with a well-researched resource of proven interventions that can be employed to stem/reverse the decline of amphibian populations." -John G Palis, Bulletin of the Chicago Herpetological Society

Download or read book Contaminants and Ecological Subsidies written by Johanna M. Kraus and published by Springer Nature. This book was released on 2020-10-15 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores the effects of aquatic contaminants on ecological subsidies and food web exposure at the boundary of aquatic and terrestrial ecosystems. It provides the first synthesis of the findings and principles governing the “dark side” of contaminant effects on ecological subsidies. Furthermore, the volume provides extensive coverage of the tools being developed to help managers and researchers better understand the implications of contaminants movement and their effects on natural resources and ecosystem processes. Aquatic and terrestrial ecosystems are linked through movements of energy and nutrients which subsidize recipient food webs. As a result, contaminants that concentrate in aquatic systems because of the effects of gravity on water and organic matter have the potential to impact both aquatic and terrestrial ecosystem processes. Within the last decade, increased attention has been paid to this phenomenon, particularly the effects of aquatic contaminants on resource and contaminant export to terrestrial consumers, and the potential implications for management. This volume, curated and edited by three field leaders, incorporates empirical results, management applications and theoretical synthesis and is a key reference for academics, government researchers and consultants.
