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

合作研究：将湖泊重新组合在一起：将沿海生产力整合到湖泊食物网Yvonne VadeoncoeurWright State University湖泊岸边(滨海区)栖息地对人类干扰和活动高度敏感。湖泊生物学家传统上将他们的研究指向湖泊生态系统的开阔水域(远洋)组成部分。因此，沿海生境对湖泊生态系统的贡献仍然鲜为人知。它们在支持湖泊生物多样性方面发挥了什么作用？它们在支持鱼类种群方面的作用是什么？该项目将评估沿海带生产力相对于远洋带生产力，并将评估这两个生境的相对重要性如何随着湖泊大小和营养水平的变化而变化。其次，它将检验这样一种假设，即沿海地带的生产力更有效地向食物链上游引导，以支持鱼类生产，从而表明沿海生境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区域食物链之间的联系，通过这样做，将提供对自然湖如何发挥作用的更全面的了解。重要的是，这项工作将为Mangaement提供关于沿海栖息地破坏和湖泊富营养化(营养丰富)如何影响沿海地区生产力的见解。这项研究将提高我们对这些栖息地变化及其对较高营养水平生产力的影响的理解。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 Yvonne VadeboncoeurWright State UniversityLake 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.
