Collaborative Research: Putting the Lake Back Together: Integrating littoral productivity into lake food webs Jake Vander Zanden University of Wisconsin-MadisonLake shore (littoral zone) habitats of lakes are highly sensitive to human disturbances and activities. Lake biologists have traditionally directed their studies towards open-water (pelagic) components of lake ecosystems. As a result, the contribution of littoral habitats to lake ecosystems remains poorly known. What is their role in supporting lake biodiversity? What is their role in supporting fish populations? This project will assess littoral zone productivity relative to pelagic zone productivity, and will assess how the relative importance of these two habitats change with lake size and nutrient levels. Second, it will test the hypothesis that littoral zone productivity is more efficiently channeled up the food chain to support fish production, thus indicating a higher importance to littoral habitats for supporting fisheries. Third, it will test whether littoral habitats support more biodiversity than pelagic habitats. This research will also investigate connections between food chains in littoral and pelagic zones, and in doing so, will provide a more holistic understanding of how natural lakes function. Importantly, this work will provide mangaement insights into how littoral habitat destruction and lake eutrophication (nutrient enrichment) affect littoral zone productivity. This research will improve our understanding of these habitat changes and the implications for the productivity of higher trophic levels. Graduate and undergraduate students will be trained in limnology and analytical chemistry.

合作研究：把湖泊重新组合在一起：将沿岸的生产力整合到湖泊食物网中威斯康星大学麦迪逊分校的杰克·范德·赞登湖泊的湖岸（沿岸的地带）栖息地对人类的干扰和活动高度敏感。湖泊生物学家传统上将他们的研究导向湖泊生态系统的开放水域（远洋）组成部分。 因此，人们对沿岸的生境对湖泊生态系统的贡献仍然知之甚少。它们在支持湖泊生物多样性方面的作用是什么？ 它们在支持鱼类种群方面起着什么作用？ 该项目将评估相对于水层区生产力的沿岸的区生产力，并将评估这两个生境的相对重要性如何随湖泊规模和营养水平而变化。 第二，它将测试的假设，即沿岸的区生产力更有效地引导食物链，以支持渔业生产，从而表明一个更重要的沿岸的生境支持渔业。 第三，它将检验沿岸的生境是否比远洋生境支持更多的生物多样性。 这项研究还将调查沿岸的和远洋区的食物链之间的联系，并在这样做的过程中，将提供一个更全面的了解如何自然湖泊的功能。 重要的是，这项工作将提供管理的见解如何沿岸的栖息地破坏和湖泊富营养化（营养富集）影响沿岸的区生产力。 这项研究将提高我们对这些栖息地变化的理解，以及对更高营养级生产力的影响。 研究生和本科生将接受湖沼学和分析化学的培训。
