Book Synopsis Population Ecology of the Leopard Frog, Rana Pipiens Pipiens Schreber at Delta Marsh, Manitoba by : Susan Bates Eddy
Download or read book Population Ecology of the Leopard Frog, Rana Pipiens Pipiens Schreber at Delta Marsh, Manitoba written by Susan Bates Eddy and published by . This book was released on 1976 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Population parameters and various aspects of the life history of the leopard frog, Rana pipiens pipiens, were studied at the University of Manitoba Field Station at Delta Marsh, Manitoba over three summers. Stomach samples contained a wide variety of animals, including tadpoles and frogs of their own species. Empty stomachs were found during cold and cloudy weather, and during migration and breeding periods. Spring migration from the lake to breeding areas in the marsh took place as soon as it was physically possible and breeding occurred immediately. Fall migration seemed to be triggered by a combination of internal and external mechanisms although the weather controlled the intensity of activity on any evening. Tadpole growth varied between sites and between years, probably because of the amount of food available. There are at least three year classes of frogs, but following the fourth summer more than one year class can form a size class - growth is fastest in the second summer, and extremely slow following the third. Females grow faster than males, but the difference is not significant. Although mortality is normally high in the tadpole stage, low water 1evels resulted in even higher mortality. This was probably because of algae toxins and lack of oxygen rather than predation. During the study there was a shift in the size structure of the population due to selective mortality on younger frogs. Unusually heavy ice and north winds following the beginning of the thaw killed younger frogs, which stayed in or near the lake in early spring. By the spring of 1974 there were very few frogs left and most of these were of the largest size class.

Book Synopsis Frogs of the United States and Canada by : C. Kenneth Dodd Jr.
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 premiere reference book on the 108 species of frogs inhabiting North America north of Mexico. An unparalleled synthesis of the biology and behavior of all native and nonindigenous species, this two-volume, extensively referenced resource has been called the most important book ever published on North American anura. Color photographs and range maps accompany species accounts detailing information on etymology, nomenclature, identification, distribution, fossil record, systematics and geographic variation, life history and ecology, behavior, population and community biology, and conservation. This new edition of the text contains the following updates: Literature citations have been added from 2012 to 2021, now spanning from 1709 to 2021. Distribution maps have been updated, recording the decreased ranges due to declining amphibian populations. Photographs have been revised to ensure the highest digital quality. Anaxyrus williamsi and Lithobates kauffeldi, newly described species, have been included. An account is also included for Gastrophryne mazatlanensis, now recognized as occurring within the United States. Generic keys have been added. A brief section on N.A. frogs in history and art have been added. Nomenclature has been updated (Incilius for Ollotis). Now the only up-to-date and comprehensive resource for those trying to protect amphibians in the US and Canada, as well as for researchers and wildlife managers who study biodiversity"--
Book Synopsis Natural History and Evolution of a Color Polymorphism in Rana Pipiens, the Northern Leopard Frog by : Eric Adam Hoffman
Download or read book Natural History and Evolution of a Color Polymorphism in Rana Pipiens, the Northern Leopard Frog written by Eric Adam Hoffman and published by . This book was released on 2003 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: A primary goal of population genetics is to identify the role of microevolutionary forces in producing observed patterns of molecular and phenotypic variation. I conducted four studies in the northern leopard frog, Rana pipiens, to determine just how mutation, migration, genetic drift, and selection influenced, genetic structure of mitochondrial DNA (mtDNA), nuclear DNA, and a single locus polymorphism that determines dorsal coloration. In the first study, I surveyed the literature concerning color and pattern polymorphisms in anurans. I conclude that anuran polymorphisms remain a rich but largely unexploited system for studying the evolution of phenotypic variation in nature. In the second study, I compared mitochondrial DNA variation from 35 populations distributed across the species' range. A phylogenetic analysis indicated R. pipiens is split into two deeply divergent mtDNA groups, a western group and an eastern group. Phylogeographic and demographic analyses indicated that although restricted gene flow with isolation by distance explained the majority of the processes influencing current genetic structure, population bottlenecks and expansions also played an important role. In the third study, I investigated mtDNA and microsatellite variation in Pacific Northwest populations of R. pipiens, where a recent range contraction had occurred. I found that peripheral populations had reduced levels of genetic variation compared to more interior populations. Moreover, I found that historic samples from peripheral population already had reduced levels of genetic variation. Therefore, low diversity in the remnant populations could not be ascribed to the recent range contraction. In the fourth study, I compared genetic structure from a suite of putatively neutral molecular markers with that derived from the color polymorphism locus. Genetic structure at the color locus, assessed both spatially and temporally, was indistinguishable from structure at neutral loci. This study exemplifies the importance of investigating for evidence of selective maintenance before studies attempt to measure the selective mechanisms maintaining a polymorphism. Overall, my research helps to elucidate how biogeographic and microevolutionary forces influence a wide-spread North American species, R. pipiens.
