The Wolves and Moose of Isle Royale


Book Description

In this exhilarating installment of the award-winning Scientists in the Field series, journey to the isolated islands of Isle Royale National Park where the longest predator/prey study in the world is being conducted along with a controversial genetic rescue to save not only the wolves and moose, but the entire island ecosystem. On Isle Royale, a unique national park more than fifty miles from the Michigan shore and about fifteen miles from Minnesota, a thrilling drama is unfolding between wolves and moose, the island’s ultimate predator and prey. For over sixty years, in what has been known as the longest study of predator and prey in the world, scientists have studied the wolves and moose of Isle Royale and the island’s ecology to observe and investigate wildlife populations. But due to illness and underlying factors, the population of wolves on the island has dropped while the number of moose has increased, putting the Isle Royale ecosystem in jeopardy. Now, for the first time ever, scientists are intervening. Join celebrated author Nancy Castaldo in this exciting journey to Isle Royale to document the genetic rescue experiment scientists there are embarking on. If they can successfully relocate twenty to thirty wolves from the mainland to Isle Royale, scientists can potentially restore the balance among wolves, moose, and trees of the island's ecosystem. Now the living laboratory experiment begins.













Winter Study


Book Description

Soon after Anna Pigeon joins the famed wolf study team of Isle Royale National Park in the middle of Lake Superior, the wolf packs begin to behave in peculiar ways. Giant wolf prints are found, and Anna spies the form of a great wolf from a surveillance plane. When a female member of the team is savaged, Anna is convinced they are being stalked, and what was once a beautiful, idyllic refuge becomes a place of unnatural occurrences and danger beyond the ordinary…

The Ecology of Large Mammals in Central Yellowstone


Book Description

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. - Unrivalled descriptions of ecological processes in a world famous ecosystem, based on information from 16 years of painstaking field work and collaborations among 66 scientists and technical experts and 15 graduate studies - Detailed studies of two charismatic North American herbivore species – elk and bison - Description of the restoration of wolves into central Yellowstone and their ecological interactions with their elk and bison prey - Illustrated with numerous evocative colour photographs and stunning maps
