Yellowstone's Wildlife in Transition
Book (italiano):
Yellowstone National Park, established in 1872, was the first national park in the world. This volume of essays begins with a foreword by the famous naturalist E. O. Wilson and goes on to detail the challenges faced by the park and its wildlife today. Editor White is Chief of Wildlife and Aquatic Resources at Yellowstone, Plumb is a Chief Wildlife Biologist for the U.S Park service and Garrott is a professor of ecology. Most of the contributors have backgrounds in environmental science or ecology or are employed by the Park Service at Yellowstone. The book starts off with some background on the park and the evolution of the Park Service's management style from an early focus on the use of the Park's resources for agricultural purposes to today's view that the park should be preserved in as close to its natural state as possible. Following this is a section on population dynamics and inter-species interactions. The reintroduction of wolves to the park and its effects on park ecology is discussed here as is animal density and some of the indirect effects of predation in the park. A section on communities and landscape-scale processes goes into detail about the effects of natural processes such as fires, floods, mudslides, volcanism, and earthquakes on shaping the park as it is today. This is also where the reader will find information on changes in the park due to global warming as well the indirect effects of wolf restoration on the vegetation in the park. The final section covers the roles of invasive, non-native species in the park such as brucellosis in Bison and a number of invasive insects, weeds, fish, and plant diseases and the park management's responses to these threats. Many invasive species are also seen to be spreading due to climate change. Annotation ©2013 Book News, Inc., Portland, OR (booknews.com)
