This book presents the results and conclusions of the longest continuous study ever undertaken for a local North American game bird population. Since 1950 abundance has been determined seasonally by direct count, nesting ecology by field searches and observation, and hunting pressure and harvest by field interviews. Land use and weather conditions also have been recorded. The period of the study saw considerable change in regional land use and included several of the most severe winters in recorded weather history. Continuing harvest of the study population did not have a progressively depressing effect on standing densities; rather it held breeding stock somewhat below K at a more productive point on the growth curve. Roseberry and Klimstra report that there was clear evidence of an 8 to 10-year cycle within the study population. They found after examining a number of cycle theories that a close temporal relationship existed between their bobwhite data and the nodal lunar cycle described by Archibald (1977). Sound field techniques, long-term data acquisition, and appropriate mathematical and statistical treatment of the data combine to provide a significant contribution to what is known of not only bobwhite but basic population ecology.

"The bibliography is a guide to recent scientific literature covering effects of agricultural conservation practices on fish and wildlife. The citations listed here provide information on how conservation programs and practices designed to improve fish and wildlife habitat, as well as those intended for other purposes (e.g., water quality improvement), affect various aquatic and terrestrial fauna"--Abstract.

This best-selling majors ecology book continues to present ecology as a series of problems for readers to critically analyze. No other text presents analytical, quantitative, and statistical ecological information in an equally accessible style. Reflecting the way ecologists actually practice, the book emphasizes the role of experiments in testing ecological ideas and discusses many contemporary and controversial problems related to distribution and abundance. Throughout the book, Krebs thoroughly explains the application of mathematical concepts in ecology while reinforcing these concepts with research references, examples, and interesting end-of-chapter review questions. Thoroughly updated with new examples and references, the book now features a new full-color design and is accompanied by an art CD-ROM for instructors. The field package also includes The Ecology Action Guide, a guide that encourages readers to be environmentally responsible citizens, and a subscription to The Ecology Place (www.ecologyplace.com), a web site and CD-ROM that enables users to become virtual field ecologists by performing experiments such as estimating the number of mice on an imaginary island or restoring prairie land in Iowa. For college instructors and students.

Nothing is more evocative of the Texas outdoors than the whistled call of the bobwhite. While the familiar two-note greeting is now just a memory for most of us who live in the state’s growing urban sprawl, this bird is an economic commodity on par with crops and livestock in some regions of Texas. Three other native species of quail also inhabit Texas. Like the northern bobwhite, the scaled quail is significant as a game bird. The other two species, Gambel’s quail and Montezuma quail, are found in limited areas of southwestern Texas and represent an important indicator of forest, rangeland, and habitat conditions. Texas Quails presents the first complete assessment of the four species of quail found in this vast state. Experts describe each of them and examine all geographic regions of the state for historical and current population trends, habitat status, and research needs. These experts also discuss management practices, hunting issues, economics, and diseases. With the recent creation of the Texas Quail Conservation Initiative, this volume provides a timely and comprehensive view of quail science and stewardship.
