Book excerpt: Exploring the factors that structure and limit species' ranges are of central importance to ecology, biogeography, and evolutionary biology because these factors are tied directly to understanding the distribution and abundance of species (ecology), the historical and ecological drivers of spatial distributions through time (biogeography), and the abiotic and biotic factors the influence the diversification of lineages and species (evolutionary biology). Testable biogeographic hypotheses, such as the abundant-center distribution (ACD) and the core-periphery hypothesis (CPH), provide the means for disentangling the factors that structure and limit species' ranges. The ACD predicts a positive relationship between the abundance of a species and how close that population is to the center or core of the species' range, while the CPH predicts that population abundance reflects the extent to which local sites satisfy the niche requirements of the species in that populations located at the geographic periphery of a species' range increasingly experience unfavorable ecological (abiotic and/or biotic) conditions that lead to declines in population density and fitness. This dissertation focuses on the wood frog (Lithobates sylvaticus), which has the largest range of any amphibian in North America, spanning approximately 40 degrees in latitude (33 to 70 ). This wide range encompasses a broad spectrum of climate conditions, from extreme cold near the Arctic Circle to high heat and humidity in the south in Alabama. Within the aforementioned biogeographic framework, I examine the effects of geography, ecology, history, genetics, and life history (growth, development, survival, and behavior) on the structure of the wood frog's range. These studies show support for predictions based on the ACD and the CPH. Populations in the core of the range have higher genetic diversity, faster developmental rates, highly active behavioral phenotypes, and have higher fitness compared to edge populations. Additionally, the work emphasizes the importance of looking at not only geographic distance from the core, as has traditionally been done in studies testing the ACD and the CPH, but also ecologically meaningful definitions, both present and historical.

This book was released on 1993-08-15 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inbreeding, the mating of close kin, and outbreeding, the mating of distant relatives or unrelated organisms, have long been important subjects to evolutionary biologists. Inbreeding reduces genetic diversity in a population, increasing the likelihood that genetic defects will become widespread and deprive a population of the diversity it may need to cope with its environment. Most plants and animals have evolved behavioral and morphological mechanisms to avoid inbreeding. However, today many endangered species exist only in small, very isolated populations where inbreeding is unavoidable, so it has become a concern for conservationists. In this volume, twenty-six experts in evolution, behavior, and genetics examine the causes and consequences of inbreeding. The authors ask whether inbreeding is as problematic as biologists have thought, under what ecological conditions inbreeding occurs, and whether organisms that inbreed have mechanisms to dampen the anticipated problems of reduced genetic variation. The studies, including theoretical and empirical work on wild and captive populations, demonstrate that many plants and animals inbreed to a greater extent than biologists have thought, with variable effects on individual fitness. Graduate students and researchers in evolutionary biology, animal behavior, ecology, and conservation biology will welcome this wide-ranging collection.

Available in PDF, EPUB and Kindle. Book excerpt: This volume represents work by five distinguished ecological geneticists, offering an up-to-date source for theoretical concepts and experiments in an exciting field. Combining ecological fieldwork and laboratory genetics, ecological genetics examines the adjustments and adaptations of wild populations to their environments. Articles focus on important interactions between genetics and population ecology, delving into issues like gene flow and migration, population differentiation, the maintenance of genetic variation, and the demographic and spatial structure of populations. The contributors--Janis Antonovics, Michael Lynch, Montgomery Slatkin, Joseph Travis, and Sara Via--emphasize the importance of population size and structure, interaction between local selection and genetic drift, and an expanded phenotype including quantitative as well as qualitative characters. This new form of ecological genetics focuses on large-scale geographic variation in demographic and genetic dynamics among small, partially isolated populations and will prove extremely valuable in natural resource management and in rare or endangered species conservation.

Download or read book The Call of the Crawfish Frog written by Michael J. Lannoo and published by CRC Press. This book was released on 2020-03-16 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crawfish Frogs (Rana areolata) have been called the most secretive frog in North America, and it is unusual in the twenty-first century – in the most scientifically advanced country in the world – that basic discoveries can still be made on an animal that inhabits a quarter of the United States. This is not only a story of the biology of Crawfish Frogs, but a case study of discovery. This volume describes the life history and natural history critical to the survival of the endangered amphibian and recommends management actions to ensure persistence. The authors tell an optimistic conservation biology story and fill a gap between science and the public. The authors have compiled and summarized the peer-reviewed literature on the biology of Crawfish Frogs, which may be one of the most interesting frogs in North America (that nobody knows about).
