Description:
At the close of the Fourth International Polar Year, we take stock of the ecological consequences of recent climate change in the Arctic, focusing on effects at population, community, and ecosystem scales. Despite the buffering effect of landscape heterogeneity, Arctic ecosystems and the trophic relationships that structure them have been severely perturbed. These rapid changes may be a bellwether of changes to come at lower latitudes and have the potential to affect ecosystem services related to natural resources, food production, climate regulation, and cultural integrity. We highlight areas of ecological research that deserve priority as the Arctic continues to warm.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Post, Eric -- Forchhammer, Mads C -- Bret-Harte, M Syndonia -- Callaghan, Terry V -- Christensen, Torben R -- Elberling, Bo -- Fox, Anthony D -- Gilg, Olivier -- Hik, David S -- Hoye, Toke T -- Ims, Rolf A -- Jeppesen, Erik -- Klein, David R -- Madsen, Jesper -- McGuire, A David -- Rysgaard, Soren -- Schindler, Daniel E -- Stirling, Ian -- Tamstorf, Mikkel P -- Tyler, Nicholas J C -- van der Wal, Rene -- Welker, Jeffrey -- Wookey, Philip A -- Schmidt, Niels Martin -- Aastrup, Peter -- New York, N.Y. -- Science. 2009 Sep 11;325(5946):1355-8. doi: 10.1126/science.1173113.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Penn State University, 208 Mueller Lab, University Park, PA 16802, USA. esp10@psu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19745143" target="_blank"〉PubMed〈/a〉
