Description:
Recent changes in Antarctic seabird populations may reflect direct and indirect responses to regional climate change. The best long-term data for high-latitude Antarctic seabirds (Adelie and Emperor penguins and snow petrels) indicate that winter sea-ice has a profound influence. However, some effects are inconsistent between species and areas, some in opposite directions at different stages of breeding and life cycles, and others remain paradoxical. The combination of recent harvest driven changes and those caused by global warming may produce rapid shifts rather than gradual changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Croxall, J P -- Trathan, P N -- Murphy, E J -- New York, N.Y. -- Science. 2002 Aug 30;297(5586):1510-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉British Antarctic Survey, Natural Environment Research Council, High Cross, Madingley Road, Cambridge CB3 0ET, UK. j.croxall@bas.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12202819" target="_blank"〉PubMed〈/a〉
