Miller and published by . This book was released on 2014 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Headwater species are organisms that are primarily constrained to the upstream terminus of river networks with limited capacities for both in-stream and overland dispersal. Movement along alternative dispersal pathways is suggested to contribute to gene flow and the overall stability of headwater populations. Six microsatellite markers were used to assess gene flow along in-network and out-of-network pathways in a species of headwater salamander, Desmognathus fuscus, over multiple spatial scales. Overall, genetic divergence was significant among all populations (Fst = 0.027 to 0.405) and at all hierarchical spatial scales. Genetic clustering analyses suggested limited gene flow within and among watersheds, indicating that both dispersal pathways are involved in maintaining gene flow among headwater populations. Increased genetic distance was associated with out-of-network distance and the degree of urbanization in upland habitat. These results suggest that significant dispersal occurred along terrestrial pathways, but dispersal resistance appears to be greatest along these pathways.

Available in PDF, EPUB and Kindle. Book excerpt: This benchmark volume documents in comprehensive detail a major environmental crisis: rapidly declining amphibian populations and the disturbing developmental problems that are increasingly prevalent within many amphibian species. Horror stories on this topic have been featured in the scientific and popular press over the past fifteen years, invariably asking what amphibian declines are telling us about the state of the environment. Are declines harbingers of devastated ecosystems or simply weird reflections of a peculiar amphibian world? This compendium—presenting new data, reviews of current literature, and comprehensive species accounts—reinforces what scientists have begun to suspect, that amphibians are a lens through which the state of the environment can be viewed more clearly. And, that the view is alarming and presages serious concerns for all life, including that of our own species. The first part of this work consists of more than fifty essays covering topics from the causes of declines to conservation, surveys and monitoring, and education. The second part consists of species accounts describing the life history and natural history of every known amphibian species in the United States.
