Book Description
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.

Book Description
This open access book describes the serious threat of invasive species to native ecosystems. Invasive species have caused and will continue to cause enormous ecological and economic damage with ever increasing world trade. This multi-disciplinary book, written by over 100 national experts, presents the latest research on a wide range of natural science and social science fields that explore the ecology, impacts, and practical tools for management of invasive species. It covers species of all taxonomic groups from insects and pathogens, to plants, vertebrates, and aquatic organisms that impact a diversity of habitats in forests, rangelands and grasslands of the United States. It is well-illustrated, provides summaries of the most important invasive species and issues impacting all regions of the country, and includes a comprehensive primary reference list for each topic. This scientific synthesis provides the cultural, economic, scientific and social context for addressing environmental challenges posed by invasive species and will be a valuable resource for scholars, policy makers, natural resource managers and practitioners.

Book Description
Short listed for the Green Earth book award In early April, as Owen and his sister search the hickories, oaks, and dogwoods for returning birds, a huge group of birds leaves the misty mountain slopes of the Yucatan peninsula for the 600-mile flight across the Gulf of Mexico to their summer nesting grounds. One of them is a Cerulean warbler. He will lose more than half his body weight even if the journey goes well. Aloft over the vast ocean, the birds encourage each other with squeaky chirps that say, “We are still alive. We can do this.” Owen’s family watches televised reports of a great storm over the Gulf of Mexico, fearing what it may mean for migrating songbirds. In alternating spreads, we wait and hope with Owen, then struggle through the storm with the warbler. This moving story with its hopeful ending appeals to us to preserve the things we love. The backmatter includes a North American bird migration map, birding information for kids, and guidance for how native plantings can transform yards into bird and wildlife habitat.

Book Description
Steppes form one of the largest biomes. Drastic changes in steppe ecology, land use and livelihoods came with the emergence, and again with the collapse, of communist states. Excessive ploughing and vast influx of people into the steppe zone led to a strong decline in nomadic pastoralism in the Soviet Union and China and in severely degraded steppe ecosystems. In Mongolia nomadic pastoralism persisted, but steppes degraded because of strongly increased livestock loads. After the Soviet collapse steppes regenerated on huge tracts of fallow land. Presently, new, restorative steppe land management schemes are applied. On top of all these changes come strong effects of climate change in the northern part of the steppe zone. This book gives an up-to-date overview of changes in ecology, climate and use of the entire Eurasian steppe area and their effects on livelihoods of steppe people. It integrates knowledge that so far was available only in a spectrum of locally used languages.

Book Description
"The two reports published here contain elements which contribute substantially to this broader spectrum of Southwestern cultural change. While primarily descriptive in nature, these two site reports, one from the western Kayenta area and one from the margin of the Mesa Verde area and the eastern Kayenta, suggest that the changes which occurred in the more centralized portions of these regions were directly related to what happened on the margins. That, while the site densities and population aggregates may not have been as high, the same factors affected these marginal areas. That conclusion could be expected, but what may not be expected is the differential response which appears to have occurred. After reading these two reports, it appears that it may be possible to discern elements of change in these fringe areas that, once defined, will provide new insight into what happened and why and in what are presently the better known areas of the Southwest. These two papers are important, in sum, not only because they are reports of work in poorly known areas, but because they do provide analyses of fringe areas, they help us to understand the Southwest generally"--From preliminary introduction.
