Effect of Global Change on the Primary Production of Antarctic coastal Ecosystems

全球变化对南极沿海生态系统初级生产力的影响随着气候变暖，南极沿海地区的海冰将减少。目前，大多数初级生产都发生在海冰中。我们认为，冰面积的减少将导致冰产量的减少，但底栖动物的产量将增加；浮游植物的产量将保持相对稳定。这些变化将显著影响中上层(即鱼类)和底栖(海星、海胆等)种群的大小，进而影响海豹和企鹅种群的大小。我们的项目将允许预测由面积减少引起的这些变化

Effect of Global Change on the Primary Production of Antarctic coastal Ecosystems. As the climate warms, sea ice in Antarctic coastal areas will reduce. Most primary production currently occurs within the sea ice. We propose that a reduction in ice extent will lead to a reduction in ice production but greater benthic production; phytoplankton production will stay relatively constant. These changes will significantly effect the size of pelagic (ie fish) and benthic (starfish, sea urchins etc) stocks, which in turn will impact on the size of seal and penguin populations. Our project will allow predictions of these changes that have been induced by a reduction in sa ice extent
