This book was released on 2020-03-31 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geographic Variation, Speciation and Clines explores the origins and development of geographic variation, divergence, and speciation. In particular it is concerned with genetic divergence as it is usually found on continents, among groups of populations isolated only by distance. Although earlier writers on this topic considered the effects of geography and dispersal, intense geographic differentiation and speciation were thought to require complete isolation. Professor Endler shows how geographic differentiation and speciation may develop in spite of continuous gene flow. Following a review of the diverse and scattered literature on gene flow and population differentiation, the author discusses the relationships among gene flow, dispersal, and migration. He then summarizes the factors which limit the geographic extent of gene flow, and those which allow steep clines to develop in the absence of barriers to gene flow. His analysis draws on examples from the field, experiments, and single- and multiple-locus models. The mechanism and conditions for parapatric speciation are presented: steepening clines, development into hybrid zones, and the evolution of sexual isolation. In the final chapter the author considers the interpretation of natural clines and the associated geographic patterns of subspecies and species.

Available in PDF, EPUB and Kindle. Book excerpt: The Nebraska Sandhills is the largest area of sand dunes in the western hemisphere, covering an area about as large as Vermont, New Hampshire, and Rhode Island combined. Unlike most dunes, the Sandhills region supports an astonishing variety of wildlife. Sixty million years ago the area lay submerged in a vast inland sea. As the land lifted and the waters receded, the sandhills were formed, built upon a sandy floor above a sandy basement. Paul A. Johnsgard's appreciation for the region includes its evolution, a process that continues today making a very special place, patiently shaped by water, wind, and time. Sometimes 450 feet higher than their sloping valleys, the hills themselves are almost entirely covered with plants that manage to survive on an unstable substrate and in a climate of merciless heat and cold. They provide homes and resting places for rare species and sustain the livelihoods of a remarkable variety of people. Though firmly established in science, this book is an extended love letter to the Sandhills region and its people, plants, and animals. Johnsgard is now in his third decade of research in the Sandhills. This Fragile Land lets others see what he sees, a land with a fascinating range of geological, biological, and ecological vistas. Paul A. Johnsgard is Foundation Professor of the School of Biological Sciences at the University of Nebraska-Lincoln. Widely published throughout the English-speaking world, he has become a foremost authority on ornithology and bird behavior. His thirty-three books include Birds of the Great Plains, The Platte, Birds of the Rocky Mountains, Those of the Gray Wind, and Diving Birds of North America, all available from the University ofNebraska Press.

Available in PDF, EPUB and Kindle. Book excerpt: This is a scientific publication of his study of Nebraskan mammals by Dr. J. Knox Jones Jr. a prolific mammalogist. He aims at, "placing on record certain information on the geographic distribution of several species—information that is thought pertinent to current studies of some of my associates." Most of this information is provided by specimens collected by him and other representatives of the University Of Kansas Museum Of Natural History, although specimens from other collections provide some of the records therein reported. The Knox Jones gopher found in parts of Texas and New Mexico is named after him.

Available in PDF, EPUB and Kindle. Book excerpt: In Wildlife of Nebraska: A Natural History, Paul A. Johnsgard surveys the variety and biology of more than six hundred Nebraska species. Narrative accounts describe the ecology and biology of the state's birds, its mammals, and its reptiles and amphibians, summarizing the abundance, distributions, and habitats of this wildlife. To provide an introduction to the state's major ecosystems, climate, and topography, Johnsgard examines major public-access natural areas, including national monuments, wildlife refuges and grasslands, state parks and wildlife management areas, and nature preserves. Including more than thirty-five line drawings by the author along with physiographic, ecological, and historical maps, Wildlife of Nebraska is an essential guide to the wildlife of the Cornhusker State.
