Wildlife Demography compiles the multitude of available estimation techniques based on sex and age data, and presents these varying techniques in one organized, unified volume. Designed to guide researchers to the most appropriate estimator based upon their particular data set and the desired level of study precision, this book provides quantitative consideration, statistical models, estimator variance, assumptions and examples of use. The authors focus on estimation techniques using sex and age ratios because this data is relatively easy to collect and commonly used by wildlife management. - Applicable to a wide array of wildlife species, including game and non-game birds and mammals - Features more than 100 annotated examples illustrating application of statistical methods - Includes more than 640 references of the analysis of nontagging data and the factors that may influence interpretation - Derives historical and ad hoc demographic methods in a modern statistical framework

Chaco Canyon, the great Ancestral Pueblo site of the eleventh and twelfth centuries, remains a central problem of Southwestern archaeology. Chaco, with its monumental “great houses,” was the center of a vast region marked by “outlier” great houses. The canyon itself has been investigated for over a century, but only a few of the more than 200 outlier great houses—key to understanding Chaco and its times—have been excavated. This volume explores the Chaco and post-Chaco eras in the northern San Juan area through extensive excavations at the Bluff Great House, a major Chaco “outlier” in Utah. Bluff’s massive great house, great kiva, and earthen berms are described and compared to other great houses in the northern Chaco region. Those assessments support intriguing new ideas about the Chaco region and the effect of the collapse of Chaco Canyon on “outlying” great houses. New insights from the Bluff Great House clarify the construction and use of great houses during the Chaco era and trace the history of great houses in the generations after Chaco’s decline. An innovative comparative study of the northern and southern portions of the Chaco world (the northern San Juan area around Bluff and the Cibola area around Zuni) leads to new ideas about population aggregation and regional abandonment in the Southwest. Appendixes present details and descriptions of artifacts recovered from Bluff: ceramics, projectile points, pollen analyses, faunal remains, bone tools, ornaments, and more. This book is one of only a handful of reports on Chacoan great houses in the northern San Juan region. It provides an in-depth study of the Chaco era and clarifies the relationship of “outlying” great houses to Chaco Canyon. Research at the Bluff Great House begins to answer key questions about the nature of Chaco and its region, and the history of the northern San Juan in the Chaco and post-Chaco worlds.

Should the wolf be reintroduced to Yellowstone National Park? Should hunting of "overabundant" deer and elk be permitted in some parks? How should grizzly bears be managed in frequently visited areas? Are mountain goats to be eliminated from Olympic National Park? R. Gerald Wright probes these and other issues of public interest in this exploration of the unique role national parks have played in the protection, study, and management of animal life. Controversy has often surrounded wildlife management, primarily when societal attitudes toward specific animals do not mesh with Park Service practices. Those practices are influenced by the public as well as by the evolution of a program of scientific study in the national parks. As park environments are increasingly threatened by growing numbers of visitors, outside land-use changes, and pollution, it is more important than ever that scientific knowledge, administrative willingness, and public support combine to help create the policies necessary for appropriate management and protection of park resources. Wright traces the history of wildlife management in the U.S. national parks, bringing together a diversity of literature and previously unpublished information that will be of concern to wildlife and land-management specialists, conservationists, and all those interested in our national parks.

At the time of European discovery, the ancient North Americanforests stretched across nearly half the continent. And while todaylittle remains of this past glory, efforts are underway to bringback some of the diverse ecosystems of that era. America's AncientForests: From the Ice Age to the Age of Discovery providesscientists and professionals with essential information for forestrestoration and conservation projects, while presenting acompelling and far-reaching account of how the North Americanlandscape has evolved over the past 18,000 years. The book weaves historical accounts and scientific knowledge into adynamic narrative about the ancient forests and the events thatshaped them. Divided into two major parts, it covers first theglaciers and forests of the Ice Age and the influences of nativepeoples, and then provides an in-depth look at these majesticforests through the eyes of the first European explorers. Changesin climate and elevation, the movement of trees northward, theassembly of modern forests, and qualities that all ancient forestsshared are also thoroughly examined. A special feature of this book is its self-contained introductionto the early history of Native American peoples and theirenvironment. The author draws on his roots in the Osage nation aswell as painstaking research through the historical record,offering a complete discussion of how the cultural practices ofhunting, agriculture, and fire helped form the ancient forests.
