Arctic Alpine Ecosystems and People in a Changing Environment
Author: Jon Børre ØrbaekPublisher: Springer Science & Business Media
ISBN: 3540485147
Category : Science
Languages : en
Pages : 446
Book Description
The European Arctic and Alpine regions are experiencing large environmental changes. These changes may have socio-economic effects if the changes affect the bioproduction, which form the basis for the marine and terrestrial food chains. This uniquely multidisciplinary book presents the various aspects of contemporary environmental changes in Arctic and Alpine Regions.

Structure and Function of an Alpine Ecosystem
Author: William D. BowmanPublisher: Oxford University Press
ISBN: 0195344294
Category : Science
Languages : en
Pages : 352
Book Description
This book will provide a complete overview of an alpine ecosystem, based on the long-term research conducted at the Niwot Ridge LTER. There is, at present, no general book on alpine ecology. The alpine ecosystem features conditions near the limits of biological existence, and is a useful laboratory for asking more general ecological questions, because it offers large environmental change over relatively short distances. Factors such as macroclimate, microclimate, soil conditions, biota, and various biological factors change on differing scales, allowing insight into the relative contributions of the different factors on ecological outcomes.

Book Description
As human populations expand and have increasing access to technol ogy, two general environmental concerns have arisen. First, human pop ulations are having increasing impact on the earth system, such that we are altering the biospheric carbon pools, basic processes of elemental cycling and the climate system of the earth. Because of time lags and feedbacks, these processes are not easily reversed. These alterations are occurring now more rapidly than at any time in the last several million years. Secondly, human activities are causing changes in the earth's biota that lead to species extinctions at a rate and magnitude rivaling those of past geologic extinction events. Although environmental change is potentially reversible at some time scales, the loss of species is irrevo cable. Changes in diversity at other scales are also cause for concern. Habitat fragmentation and declines in population sizes alter genetic di versity. Loss or introduction of new functional groups, such as nitro gen fixers or rodents onto islands can strongly alter ecosystem processes. Changes in landscape diversity through habitat modification and frag mentation alter the nature of processes within and among vegetation patches. Although both ecological changes altering the earth system and the loss of biotic diversity have been major sources of concern in recent years, these concerns have been largely independent, with little concern for the environmental causes the ecosystem consequences of changes in biodiversity. These two processes are clearly interrelated. Changes in ecological systems cause changes in diversity.
