DOWNLOAD EBOOK →Excerpt from The Screech Owl, Vol. 71: Its Life History and Population Ecology in Northern Ohio Screech owls began using the nest boxes in northern Ohio much earlier than wood ducks. In fact, we have found wood ducks nesting in boxes after young screech owls have fledged. It is our subjective assessment that screech owls keep starlings (sturnus vulgaris), which are much more competitive than the owls, out of the nest boxes within the owls' feeding areas. Upon occasion, starlings will bury wood duck eggs under their nesting material and cause the hen to desert. We therefore contend that wood duck nesting success is enhanced by the presence of screech owl nesting. Adequate numbers of nest boxes should be provided for both species.

DOWNLOAD EBOOK →The eastern screech owl, widespread over the eastern half of North America and noticeably tolerant of human activity, is one of America's most familiar birds. Residing naturally in wooded environs with tree cavities, this owl lives well in suburbia and can be found nesting in mailboxes, porch columns, and purple martin houses. Based on a twenty-five-year study, biologist Frederick R. Gehlbach tells the life story of the eastern screech owl, focusing on case studies of suburban and rural study plots in Central Texas. This is the first thorough study of major life-history, behavioral, and ecological features of the species. Indeed, it is the first concurrent, comparative study of an urban and a rural population of any New World animal. Told in a personal voice, the story of these birds will interest all who have not lost touch with their ancestral world. However, Gehlbach has also included quantitative data and analysis of interest to ecologists, wildlife biologists, and ornithologists. Photographs (including color shots of the gray and rufous phases), figures, and tables provide further detail. Gehlbach's investigations have been those of not only an academic ecologist, but a suburbanite curious about his natural surroundings. The result is a model of research on species population dynamics and adaptation, yielding an emerging picture of what the eastern screech owl needs for successful coexistence with human neighbors.

DOWNLOAD EBOOK →The relentless loss of biodiversity is among the greatest problems facing the world today. The third edition of this established textbook provides an updated and comprehensive overview of the essential background, concepts, and tools required to understand how genetics can be used to conservespecies, reduce threat of extinction, and manage species of ecological or commercial importance. This edition is thoroughly revised to reflect the major contribution of genomics to conservation of populations and species. It includes two new chapters: "Genetic Monitoring" and a final "ConservationGenetics in Practice" chapter that addresses the role of science and policy in conservation genetics.New genomic techniques and statistical analyses are crucial tools for the conservation geneticist. This accessible and authoritative textbook provides an essential toolkit grounded in population genetics theory, coupled with basic and applied research examples from plants, animals, and microbes. Thebook examines genetic and phenotypic variation in natural populations, the principles and mechanisms of evolutionary change, evolutionary response to anthropogenic change, and applications in conservation and management.Conservation and the Genomics of Populations helps demystify genetics and genomics for conservation practitioners and early career scientists, so that population genetic theory and new genomic data can help raise the bar in conserving biodiversity in the most critical 20 year period in the historyof life on Earth. It is aimed at a global market of applied population geneticists, conservation practitioners, and natural resource managers working for wildlife and habitat management agencies. It will be of particular relevance and use to upper undergraduate and graduate students taking coursesin conservation biology, conservation genetics, and wildlife management.
