Book excerpt: The Cascades frog (Rana cascadae) is a montane, lentic-breeding amphibian that has become rare in the southern Cascade Range and remains relatively widespread in the Klamath Mountains of northern California. In the southern Cascades, remaining populations occur primarily in meadow habitats where the fungal disease, chytridiomycosis, and habitat desiccation pose threats to persistance. Major risk factors in the Klamath Mountains include introduced fish and chytridiomycosis. Conservation actions are needed for the Cascades frog in California and especially in the southern Cascades. Conservation options include restoration of breeding pools in the southern Cascades, fish removals in the Klamath Mountains, and adaptive methods to help alleviate the effects of chytridiomycosis rangewide.

Available in PDF, EPUB and Kindle. Book excerpt: This study combined both intensive and long-term sampling to provide information on Cascades frog, Rana cascadae, landscape use at multiple spatial scales in the Trinity Alps Wilderness of Northern California. Mark-recapture and radio telemetry were used from 2003 to 2008 to determine key ecological components of R. cascadae life history, resource use, spatial patterns, migrations and dispersal for all post-metamorphic age groups. Rana cascadae often used different aquatic resources for breeding, summer foraging and overwintering. Resources were commonly found to be spatially or temporally separated and frogs were observed to move seasonally among them. Lentic habitats fed by groundwater springs were used extensively for both breeding and overwintering. Seasonal migration events were common among isolated habitats. Single sites were not likely to contain self-sustaining sub-populations, but contribute to a matrix of required seasonal resources across a patchy landscape. The majority of dispersal events occurred between patches located inside a single basin, however, one percent of frogs dispersed among four of six neighboring basins. Consequently the conservation of R. cascadae populations requires management of key resources, processes, and an integration of several spatial scales that reflect the whole range of life history attributes.

Download or read book Frogs of the United States and Canada written by C. Kenneth Dodd Jr. and published by JHU Press. This book was released on 2023-06-20 with total page 991 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most thorough, updated guide to frogs and toads in the United States and Canada available. A stunning diversity of frog species can be found from coastal swamps to lofty mountain peaks, and from the Florida Keys to the Arctic Ocean. They live in subtropical lowlands, grassland prairies, deserts, and alpine-tundra habitats. Some species have restricted habitat requirements, whereas others occur contiguously from the arid plains or humid southeastern forests to the high tundra. In this new edition of Frogs of the United States and Canada, C. Kenneth Dodd Jr. tours the reader through the marvelous world of North American frogs. Covering 114 native and introduced species from all US states and Canadian provinces, this comprehensive reference on the biology, behavior, and conservation of the Order Anura includes detailed and updated information on • past and present distribution • life history and demography • reproduction and diet • landscape ecology and evolution • diseases, parasites, and threats from toxic substances • conservation and management Hundreds of occurrence maps, line drawings, and new color photographs of frogs and their habitats enhance the text. The most thorough treatment of the life histories, distribution, and status of North American frogs ever produced, Frogs of the United States and Canada has been the go-to reference for naturalists, scientists, and resource managers in their efforts to understand and conserve frogs, their habitats, and biodiversity for over a decade. Based on a meticulously updated examination of more than 8,000 references current through 2021, this second edition ensures Dodd's master work will remain an unparalleled resource for years to come.

Download or read book Population and Conservation Genetic Structure of the Cascades Frog Rana Cascadae Throughout the Species Range written by Kirsten J. Monsen and published by . This book was released on 2002 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major goal of conservation biology is to elucidate the population genetic structure in threatened species and assess the relative importance of the evolutionary forces that shape that population genetic structure. I conducted three studies in the declining amphibian Rana cascadae to assess levels of population genetic differentiation and the relative importance of gene flow versus random genetic drift throughout the species' range. In the first study, 1 examined phylogeographic structure on a species-wide geographic scale with both mitochondrial and nuclear molecular markers. I found three mitochondrial groups within R. cascadae that are as divergent at the mitochondrial DNA as sister species. However, I only found two nuclear groups within R. cascadae, suggesting there are two Distinct Population Segments and three Management Units within the species' range. In the second study, I compared sequence data from mtDNA and nuclear DNA of the three R. cascadae mtl)NA groups to several closely related Pacific Northwestern ranid species. I found the surprising result that the mtDNA of R. aurora aurora is more closely related to the mtDNA of' R. cascadae than to the mtDNA of its own subspecies R. aurora drayloni. The nuclear data support the sub-specific relationship between R. aurora aurora and R. aurora draytoni. This result is most likely due to incomplete lineage sorting of ancestral mtDNA alleles. Finally, in the third study, I examined the relative importance of gene flow versus random genetic drift on a fine geographic scale using microsatellite loci. Additionally, I estimated the long-term effective population sizes and genetic neighborhood size for 11 R. cascadae populations. Rana cascadae shows extreme isolation by distance with very little gene flow occurring past a distance of 10 km. Long-term effective population sizes were unrealistically large for current effective population sizes, but the estimates oF genetic neighborhood size are consistent with those expected based on current census population size and genetic neighborhood size in other amphibians. My research suggests Rana cascadae should be managed as three separate groups corresponding to the Olympic Peninsula, the Cascades of Washington and Oregon, and Northern California. Additionally, R. cascadae exhibits extreme isolation by distance with reduced gene flow at distances greater than 10 km, suggesting metapopulation structure is weak, and populations that go extinct are unlikely to be re-colonized quickly despite the presence of nearby R. cascadae populations.
