This book was brought to my attention and so I thought I would pass it on to any interested readers. The name of the book is, “The Ecology of Large Mammals in Central Yellowstone“. From the book’s website:

This book is an authoritative work on the ecology of some of America?s most iconic large mammals in a natural environment – and of the interplay between climate, landscape, and animals in the interior of the world?s first and most famous national park. Central Yellowstone includes the range of one of the largest migratory populations of bison in North America as well as a unique elk herd that remains in the park year round. These populations live in a varied landscape with seasonal and often extreme patterns of climate and food abundance. The reintroduction of wolves into the park a decade ago resulted in scientific and public controversy about the effect of large predators on their prey, a debate closely examined in the book. Introductory chapters describe the geography, geology and vegetation of the ecosystem. The elk and bison are then introduced and their population ecology described both pre- and post? wolf introduction, enabling valuable insights into the demographic and behavioral consequences for their ungulate prey. Subsequent chapters describe the wildlife-human interactions and show how scientific research can inform the debate and policy issues surrounding winter recreation in Yellowstone. The book closes with a discussion of how this ecological knowledge can be used to educate the public, both about Yellowstone itself and about science, ecology and the environment in general. Yellowstone National Park exemplifies some of the currently most hotly debated and high-profile ecological, wildlife management, and environmental policy issues and this book will have broad appeal not only to academic ecologists, but also to natural resource students, managers, biologists, policy makers, administrators and the general public.

What was also sent to me were three maps taken from this book that show three stages of elk distribution in central Yellowstone. Map 1 show the distribution of elk prior to the colonization of wolves to the park. Map 2 shows the distribution of elk about 3 or 4 years after wolf reintroduction and Map 3 shows elk distribution “post wolf” or around 2006.

I was told by the person who sent me the maps that the reason it shows the elk congregated around the Madison River is that the water is deep enough for the elk to escape the onslaught of the wolves.
