Download or read book Science and the Endangered Species Act written by Committee on Scientific Issues in the Endangered Species Act and published by National Academies Press. This book was released on 1995-10-27 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Endangered Species Act (ESA) is a far-reaching law that has sparked intense controversies over the use of public lands, the rights of property owners, and economic versus environmental benefits. In this volume a distinguished committee focuses on the science underlying the ESA and offers recommendations for making the act more effective. The committee provides an overview of what scientists know about extinction--and what this understanding means to implementation of the ESA. Habitat--its destruction, conservation, and fundamental importance to the ESA--is explored in detail. The book analyzes Concepts of species--how the term "species" arose and how it has been interpreted for purposes of the ESA. Conflicts between species when individual species are identified for protection, including several case studies. Assessment of extinction risk and decisions under the ESA--how these decisions can be made more effectively. The book concludes with a look beyond the Endangered Species Act and suggests additional means of biological conservation and ways to reduce conflicts. It will be useful to policymakers, regulators, scientists, natural-resource managers, industry and environmental organizations, and those interested in biological conservation.
Download or read book Species Diversity Changes and Habitat Associations of Small Mammals at Ash Meadows National Wildlife Refuge Nye County Nevada written by Tara Katherine Raabe and published by . This book was released on 2011 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ash Meadows National Wildlife Refuge (Ash Meadows NWR), a spring-fed wetlands and alkaline desert system located in the Mojave Desert in Nye County, Nevada, supports 25 species of endemic plants and animals (5 currently listed as federally endangered). Human activities have caused scale habitat alterations to the land and biotic communities of Ash Meadows NWR through peat-mining and spring diversions for irrigation purposes. Restoration projects are currently being developed because of the endangered endemic species. My objectives were to determine changes in small mammal diversity over time and identify habitat types and vegetative characteristics inhabited by small mammals. Information on small mammal specimens collected for two surveys in 1891 and 1933 was used to assess species diversity changes over time. Species diversity in 1891 was similar to the results of my study; however, diversity in 1933 was not similar. Habitats differed in structural components seasonally as well as between capture and non-capture trap sites mostly because of the unique seeps and springs system present. Small mammals were primarily associated with shrub dominated and graminoid dominated habitat associations. Overall, shrub and graminoid dominated habitats are important for small mammal communities; however, other habitat types are equally important in sustaining biodiversity at Ash Meadows NWR.

Download or read book Endangered and Threatened Species of the Platte River written by National Research Council and published by National Academies Press. This book was released on 2005-02-24 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tension between wildlife protection under the Endangered Species Act and water management in the Platte River Basin has existed for more than 25 years. The Platte River provides important habitat for migratory and breeding birds, including three endangered or threatened species: the whooping crane, the northern Great Plains population of the piping plover, and the interior least tern. The leading factors attributed to the decline of the cranes are historical overhunting and widespread habitat destruction and, for the plovers and terns, human interference during nesting and the loss of riverine nesting sites in open sandy areas that have been replaced with woodlands, sand and gravel mines, housing, and roadways. Extensive damming has disrupted passage of the endangered pallid sturgeon and resulted in less suitable habitat conditions such as cooler stream flows, less turbid waters, and inconsistent flow regimes. Commercial harvesting, now illegal, also contributed to the decline of the sturgeon. Endangered and Threatened Species of the Platte River addresses the habitat requirements for these federally protected species. The book further examines the scientific aspects of the U.S. Fish and Wildlife Service's instream-flow recommendations and habitat suitability guidelines and assesses the science concerning the connections among the physical systems of the river as they relate to species' habitats.
Download or read book The Unified Neutral Theory of Biodiversity and Biogeography written by Stephen P. Hubbell and published by Princeton University Press. This book was released on 2011-06-27 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite its supreme importance and the threat of its global crash, biodiversity remains poorly understood both empirically and theoretically. This ambitious book presents a new, general neutral theory to explain the origin, maintenance, and loss of biodiversity in a biogeographic context. Until now biogeography (the study of the geographic distribution of species) and biodiversity (the study of species richness and relative species abundance) have had largely disjunct intellectual histories. In this book, Stephen Hubbell develops a formal mathematical theory that unifies these two fields. When a speciation process is incorporated into Robert H. MacArthur and Edward O. Wilson's now classical theory of island biogeography, the generalized theory predicts the existence of a universal, dimensionless biodiversity number. In the theory, this fundamental biodiversity number, together with the migration or dispersal rate, completely determines the steady-state distribution of species richness and relative species abundance on local to large geographic spatial scales and short-term to evolutionary time scales. Although neutral, Hubbell's theory is nevertheless able to generate many nonobvious, testable, and remarkably accurate quantitative predictions about biodiversity and biogeography. In many ways Hubbell's theory is the ecological analog to the neutral theory of genetic drift in genetics. The unified neutral theory of biogeography and biodiversity should stimulate research in new theoretical and empirical directions by ecologists, evolutionary biologists, and biogeographers.
