Book Description
Proper management of water resources can take many forms, and requires the knowledge and expertise to work at the intersection of mathematics, geology, biology, geography, meteorology, political science, and even psychology. This book provides an essential foundation in water management and development concepts and practices, dissecting complex topics into short, understandable explanations that spark true interest in the field. Approaching the study of water resources systematically, the discussion begins with historical perspective before moving on to physical processes, engineering, water chemistry, government regulation, environmental issues, global conflict, and more. Now in its fourth edition, this text provides the most current introduction to a field that is becoming ever more critical as climate change begins to threaten water supplies around the world. As geography, climate, population growth, and technology collide, effective resource management must include a comprehensive understanding of how these forces intermingle and come to life in the water so critical to us all.

Book Description
For centuries, criminologists have looked for scientific ways to study, understand, and ultimately prevent crime. In this volume, a unique offense, poaching, is explored in various contexts to determine what opportunity structures favor this crime and how situational crime prevention may reduce its prevalence. The data sources used range from publically available secondary data about animal populations, to interviews with hunters, to actual law enforcement data collected inside protected areas. Various methods are utilized to look for patterns in poaching behaviour regarding where poachers strike, which species they target and their modus operandi. Collectively, the volume shows that principles of criminal opportunity theory and situational crime prevention are useful for studying and preventing poaching in a variety of contexts. The methods employed by each chapter are easily replicated and meant to stimulate empirical poaching research where data is available. While the theoretical grounding of this volume is drawn from criminology, it is written for a broad audience of academics, practitioners and those interested in wildlife conservation.

Book Description
Lesser (Grus canadensis canadensis) and Canadian (G. c. rowani) sandhill cranes were studied from 1974 through 1977 in portions of the Central Flyway and Saskatchewan, Canada. The primary purposes of the study were to obtain estimates of (1) the lesser and Canadian sandhill crane populations during the fall and spring, (2) percent of juveniles in the population, and (3) hunting pressure, harvest, and crippling loss. Visual estimates of the numbers of cranes occurring within the main fall staging areas on the principal wintering grounds were made during periods of peak migration each October, and on the Platte River in Nebraska each spring. Feeding, roosting, and flying sandhill cranes were aged throughout the study area during fall and winter with the aid of binoculars and spotting scopes.

Book Description
"The authors have done a superb job of distilling a vast amount of information on the biology of the terrestrial mammals of the eastern United States in a style that will not only satisfy the expert's need for accurate data but will also appeal to students and others interested in natural history." —James N. Layne, Archbold Biological Station In their definitive work on eastern mammals, John O. Whitaker, Jr., and W. J. Hamilton, Jr., vividly convey their sheer delight at the variety and abundance of mammalian life. They have brought together a wealth of biological information and applied a biological subspecies concept to the mammals of the eastern United States. Their research extends "from the high reaches of Mount Katahdin in northern Maine, where water shrews and moose hold company," to the unglaciated hills of southern Indiana, where pygmy shrews (each weighing less than a dime) lived undetected until 1981. From there, they reach to "the cypress swamps of lower Florida, where the spoor of the mountain lion may be seen."*Describes the animals, their behavior, and dispersion in all 27 states east of the Mississippi River.*Almost entirely rewritten, this edition provides an abundance of scientific information in combination with anecdotes, field notes, and an underlying reverence for the fragile diversity of animal life. *Illustrations include 110 range maps, 167 black-and-white photographs, and 92 color images.*Covers 121 species, 17 more than in the previous edition. *Uses a biological subspecies concept, showing the results of evolution through differentiation. *Provides keys to orders and genera, anatomical line drawings. *Summarizes information on endangered and threatened species for each of the eastern states. *Lists state mammal books in the literature section.
