9520663 LODGE This proposal will test the hypothesis that the relative importance of benthic and pelagic primary production in lake food webs is dependent on lake trophic status and is regulated by fish. Previous results indicate that benthic and pelagic organisms are strongly linked through trophic relationships and form important conduits for carbon and nitrogen flow. Fish structure benthic and pelagic communities and are important vectors of organic material and nutrients between benthic and pelagic habitats. A stable isotope method will be used to integrate this research into a comprehensive understanding of benthic-pelagic trophic links. The stable isotopes will be used to determine the trophic links between pelagic food webs, benthic macroinvertebrate communities, and benthic algae.

9520663 Lodge该提案将检验以下假设：底栖底栖生产在湖泊食品网中的相对重要性取决于湖泊的营养状况，并且受鱼的调节。 先前的结果表明，底栖生物和骨髓生物通过营养关系与碳和氮流的重要管道密切相关。 鱼类结构底栖和骨髓群落是底栖栖息地和骨髓栖息之间的有机物质和营养的重要载体。 一种稳定的同位素方法将用于将这项研究整合到对底栖 - - - - - 斜向营养环节的全面理解中。 稳定的同位素将用于确定骨膜网，底栖大型无脊椎动物群落和底栖藻类之间的营养联系。
