Download or read book A Naturalist s Guide to the Great Plains written by Paul A. Johnsgard and published by Lulu.com. This book was released on 2018 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book documents nearly 500 US and Canadian locations where wildlife refuges, nature preserves, and similar properties protect natural sites that lie within the North American Great Plains, from Canada's Prairie Provinces to the Texas-Mexico border. Information on site location, size, biological diversity, and the presence of especially rare or interesting flora and fauna are mentioned, as well as driving directions, mailing addresses, and phone numbers or internet addresses, as available. US federal sites include 11 national grasslands, 13 national parks, 16 national monuments, and more than 70 national wildlife refuges. State properties include nearly 100 state parks and wildlife management areas. Also included are about 60 national and provincial parks, national wildlife areas, and migratory bird sanctuaries in Canada's Prairie Provinces. Many public-access properties owned by counties, towns, and private organizations are also described.
Download or read book Handbook of Avian Hybrids of the World written by Eugene M. McCarthy and published by Oxford University Press. This book was released on 2006-02-16 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than 5,000 works cited, Handbook of Avian Hybrids of the World is the greatest compendium of information ever published on hybridization in birds. Worldwide in scope, it provides information on all reported avian crosses, not only those occurring in captivity, but also in a natural setting (approximately 4,000 crosses are covered). This book is a basic reference, intended both for the serious birder and the professional biologist. McCarthy's work fills a need for reference material that takes into account the last half century of data. It will be of interest to workers in a wide variety of fields, ranging from animal behavior to genetics, ecology, zoology, and systematics. In fact, it will make fascinating reading for anyone interested in birds and the natural world.

Download or read book Hybrid Zones and the Evolutionary Process written by Richard Gerald Harrison and published by Oxford University Press, USA. This book was released on 1993 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hybrid zones--geographical areas in which the hybrids of two races are found--have attracted the attention of evolutionary biologists for many years, both because they are windows on the evolutionary process and because the patterns of animals and plant variation seen in hybrid zones do notfit the traditional classification schemes of taxonomists. Hybrid zones provide insights into the nature of the species, the way barriers to gene exchange function, the genetic basis of those barriers, the dynamics of the speciation process. Hybrid Zones and the Evolutionary Process synthesizes theextensive research literature in this field and points to new directions in research. It will be read with interest by evolutionary biologists, geneticists, and biogeographers.
Download or read book Current Ornithology written by Richard Johnston and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: The appearance of the first volume of a projected series is the occasion for comment on scope, aims, and genesis of the work. The scope of Current Ornithology is all of the biology of birds. Ornithology, as a whole-organism science, is concerned with birds at every level of bi ological organization, from the molecular to the community, at least from the Jurassic to the present time, and over every scholarly discipline in which bird biology is done; to say this is merely to expand a dic tionary definition of "ornithology. " The aim of the work, to be realized over several volumes, is to present reviews or position statements con cerning the active fields of ornithological research. The reviews will be relatively short, and often will be done from the viewpoint of a readily identified group or school. Such a work could have come into being at any time within the past fifty years, but that Current Ornithology appears now is a result of events that are only seven to eight years old. One important event was the initiation in 1975-1976 of the Workshop on a National Plan for Ornithology, under the directorship of James R. King and Walter J. Bock, cosponsored by the American Ornithologists' Union and the Na tional Science Foundation. Part of the Workshop's interests lay in pub lications resources, and certain kinds of information on publications were obtained by means of a questionnaire.

Download or read book Genetics of Mate Choice From Sexual Selection to Sexual Isolation written by W.J. Etges and published by Springer Science & Business Media. This book was released on 2003-01-31 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic studies aimed at understanding the origin of species are dominating major scientific journals. In the past decade, genetic tools that were previously available only in model systems have become accessible to investigators working on nearly all species. Concurrent with these technical advances has been an increase in understanding of both the importance of considering the ecological context of speciation and testing hypotheses about causes for species formation. Many recent studies suggest a prominent role of sexual selection in species formation. These advances have produced a need for a synthesis of what we now understand about speciation, and perhaps more importantly, where we should go from here. In this volume, several leading investigators and rising stars have contributed reviews and/or novel primary research findings aimed at understanding the ultimate mystery on which Darwin named his most famous and influential book. Fundamental to the origin of species is the evolution of mate choice systems. This collection of papers discusses burgeoning genetic, evolutionary, and ecological approaches to understanding the origins of mating discrimination and causes of premating reproductive isolation both within and between species. The individual contributions span a wide spectrum of disciplines, taxa, and ideas (some controversial). This synthesis brings together several of the most recent ideas with supporting empirical data. This book will be of particular interest to both undergraduate and postgraduate researchers and students and researchers in the field of evolutionary biology, genetics and animal behaviour.
