tailieunhanh - Arctic Alpine Ecosystems and People in a Changing Environment

This book addresses the significant environmental changes experienced by high latitude and high altitude ecosystems at the beginning of the 21st century. Increased temperatures and precipitation, reduction in sea ice and glacier ice, the increased levels of UV-radiation and the long-range transported contaminants in arctic and alpine regions are stress factors that challenge terrestrial and aquatic ecosystems. The large natural variation in the physical parameters of these extreme environments is a key factor in structuring the biodiversity and biotic productivity, and the effect of the new stress factors can be critical for the population structures and the interaction between species. These changes may also have socio-economic effects if the changes. | Jon Borre 0rba k Roland Kallenborn Ingunn Tombre Else Nost Hegseth Stig Falk-Petersen Alf Hảkon Hoel Editors .
