"Death watch", "poster child for pollution problems", "deadly intruders", "dead zone", "dead", "danger of collapse", "ailing", "sick", "stinky scum", "fouling" and "poison harvest" are all terms that have been used recently to describe Lake Erie. The lake's current ecological state behind this unfortunate characterization is threatening a multi-billion dollar fishing and tourism industry. Today the Great Lakes, are a dramatically different ecosystem than they were a hundred years ago. This new ecological state (regime) of the Great Lakes needs to be better understood, and soon, since these lakes provide our society with a panoply of ecosystem services including drinking water for the City of Toronto, recreational and commercial fishing, tourism, and transportation of goods, while enhancing regional biodiversity and wetlands. Our project ultimately aims to link aquatic ecosystem services to the current state (regime) of Lake Erie, one of the Great Lakes. Specifically, we will examine the current foodweb structure of different areas in the lake and its connections to key processes that control the lake's carbon balance (carbon = energy). Our results will provide us with an opportunity to test if carbon/energy flux is sufficient to support the world's largest commercial fisheries historically supported by Lake Erie.

“死亡观察”、“污染问题的典型儿童”、“致命入侵者”、“死区”、“死亡”、“倒塌危险”、“生病”、“生病”、“臭渣”、“污损”和“毒物收获”都是最近用来描述伊利湖的术语。这种不幸特征背后的湖泊目前的生态状况正在威胁着价值数十亿美元的渔业和旅游业。今天的五大湖生态系统与一百年前截然不同。需要尽快更好地了解五大湖的这种新生态状态（制度），因为这些湖泊为我们的社会提供了全套生态系统服务，包括多伦多市的饮用水、休闲和商业捕鱼、旅游和交通的货物，同时增强区域生物多样性和湿地。我们的项目最终目标是 将水生生态系统服务与五大湖之一伊利湖的现状（制度）联系起来。具体来说，我们将检查湖泊中不同区域当前的食物网结构及其与控制湖泊碳平衡（碳=能量）的关键过程的联系。我们的结果将为我们提供一个机会来测试碳/能量通量是否足以支持历史上由伊利湖支持的世界上最大的商业渔业。
