Book Description
The boreal forest is one of the world's great ecosystems, stretching across North America and Eurasia in an unbroken band and containing about 25% of the world's closed canopy forests. The Kluane Boreal Forest Ecosystem Project was a 10-year study by nine of Canada's leading ecologists to unravel the impact of the snowshoe hare cycle on the plants and the other vertebrate species in the boreal forest. In much of the boreal forest, the snowshoe hare acts as a keystone herbivore, fluctuating in 9-10 year cycles, and dragging along secondary cycles in predators such as lynx and great-horned owls. By manipulating the ecosystem on a large scale from the bottom via fertilizer additions and from the top by predator exclosures, they have traced the plant-herbivore relationships and the predator-prey relationships in this ecosystem to try to answer the question of what drives small mammal population cycles. This study is unique in being large scale and experimental on a relatively simple ecosystem, with the overall goal of defining what determines community structure in the boreal forest. Ecosystem Dynamics of the Boreal Forest: The Kluane Project summarizes these findings, weaving new discoveries of the role of herbivores-turned-predators, compensatory plant growth, and predators-eating-predators with an ecological story rich in details and clear in its findings of a community where predation plays a key role in determining the fate of individuals and populations. The study of the Kluane boreal forest raises key questions about the scale of conservation required for boreal forest communities and the many mammals and birds that live there.

Applied Ecology and Natural Resource Management

ISBN: 9780521009751
Category : Nature
Languages : en
Pages : 188
Book Description
The science of ecology and the practice of resource management are critical to our understanding of the Earth's ecosystems and our efforts to conserve them. This book attempts to bridge the gap between ecology and natural resource management and in particular, focuses on the discipline of plant ecology as a foundation for vegetation and wildlife management. It describes how concepts and approaches used by ecologists to study communities and ecosystems can be applied to their management. Guy R. McPherson and Stephen DeStefano emphasise the importance of thoughtfully designed and carefully conducted scientific studies to both the advancement of ecological knowledge and the application of techniques for the management of plant and animal populations. The book is aimed at natural resource managers, as well as graduate and advanced undergraduate students, who are familiar with fundamental ecological principles and who want to use ecological knowledge as a basis for the management of ecosystems.
The Inadequate Environment

Book Description
Ecology is characterized by a rapidly growing complexity and diversity of facts, aspects, examples, and observations. What is badly needed is the development of common patterns, of rules that, as in other sciences such as physics, can more generally explain the increasing complexity and variability we observe. Tom White, being one of the "seniors" in ecology, makes such an attempt in his book. the pattern he shows and explains with numerous examples from the entire animal kingdom is a universal hunger for nitrogen, a misery that drives the ecology of all organisms. He advocates that the awareness of this fundamental role that the limitation of nitrogen plays in the ecology of all organisms should be as a much part of each ecologis's intellectual equipment as is the awareness of the fact of evolution by means of natural selection. His claim is that not "enery" but "nitrogen" is the most limited "currency" in the animal world for the production and growth of their young.
