RUI: Landscape Control of Trophic Structure in Arctic Alaskan Lakes

9509348好时RUI：北极阿拉斯加湖泊营养状态的景观控制本项目测试地貌学在确定阿拉斯加北坡湖泊食物网结构方面的重要性。湖泊出流梯度，湖泊深度和湖泊面积被假定为在该地区的湖泊鱼类组成的重要控制。鱼类群落的结构，然后预测在这些湖泊的整个食物网的结构中发挥重要作用。将用遥感数据、确定湖泊融化率的合成孔径雷达和实地调查来检验这些假设。这些偏远的湖泊，不受人类引进鱼类物种的影响，允许对湖泊生态系统的地貌和食物网之间的相互作用进行严格的测试。

9509348 Hershey RUI: Landscape Control of Trophic Status in Arctic Alaskan Lakes This project tests the importance of geomorphology in determining food web structure for lakes on the North Slope of Alaska. Lake outflow gradient, lake depth, and lake area are postulated to be important controls on the fish species composition of lakes in this region. The structure of the fish community is then predicted to play a major role in the structure of the entire food web of these lakes. The hypotheses will be tested with remote sensing data, synthetic aperature radar (SAR) for determining lake thawing rates, and field surveys. These remote lakes, unimpacted by fish species introductions by humans, allow a rigorous test of the interactions between geomorphology and food webs of lake ecosystems.
