Collaborative Research: Putting the Lake Back Together: Integrating Littoral Productivity Into Lake Food Webs

合作研究：将湖泊整合在一起：将沿海生产力整合到湖泊食物网中威斯康星大学麦迪逊分校湖岸（沿海地带）湖泊的栖息地对人类干扰和活动高度敏感。传统上，湖泊生物学家的研究方向是湖泊生态系统的开放水域（远洋）组成部分。因此，沿海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？它们在维持鱼类数量方面扮演什么角色？该项目将评估沿海区相对于远洋区的生产力，并将评估这两种栖息地的相对重要性如何随湖泊大小和营养水平而变化。其次，它将检验沿海地区生产力更有效地引导到食物链上游以支持鱼类生产的假设，从而表明沿海栖息地对支持渔业的重要性更高。第三，它将测试沿海栖息地是否比远洋栖息地支持更多的生物多样性。这项研究还将调查沿海和远洋地区食物链之间的联系，并在此过程中，将对自然湖泊的功能提供更全面的了解。重要的是，这项工作将为滨海生境破坏和湖泊富营养化（营养物富集）如何影响滨海带生产力提供管理见解。这项研究将提高我们对这些栖息地变化的理解以及对高营养水平生产力的影响。研究生和本科生将接受湖沼学和分析化学方面的培训。

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.
