Assessing the effects of cumulative stressors on ecosystem structure and function presents one of the most important yet vexing problems for environmental management. This issue has particularly been highlighted by First Nations who are concerned about multiple developments being undertaken in their Traditional Territories which represent a significant land base in Canada. Measurements to quantify cumulative effects must reflect the long lived and widespread effects of such cumulative stressors. Recent advances in food web ecology have identified ecosystem structures that are essential for the maintained and stable functioning of the ecosystems upon which we rely. Specifically, the role of top predators and distinct energy channels in the maintenance of ecosystem function have been highlighted, and it is these very structures that must be maintained in the face of human pressures. The goal of this research program is to test the implementation of such measurements in assessing cumulative effects in the Traditional Territories of the Saugeen Ojibway Nations (specifically the Bruce Peninsula and Lake Huron). Gradients in cumulative stressors have already been established for the region. This work will build on that knowledge to test the hypothesis that fundemental food web structures vary predictably with cumulative stress. Thus, this research program promises to both develop meaningful metrics for quantifying cumulative effects in cooperation with First Nations that have an established record of environmental management in their Traditional Territories.

评估累积压力源对生态系统结构和功能的影响提出了环境管理中最重要但令人烦恼的问题之一。 原住民特别强调了这个问题，他们担心在其传统领土上所进行的多个发展，这些发展代表了加拿大的重要土地基础。量化累积效应的测量必须反映这种累积应激源的长期和广泛的影响。 食品网络生态学的最新进展已经确定了生态系统结构，这些结构对于我们依靠的生态系统的维护和稳定功能至关重要。 具体而言，顶级捕食者和独特的能量通道在维持生态系统功能中的作用已得到强调，正是这些结构必须在人类压力下保持。 该研究计划的目的是测试在评估Saugeen Ojibway国家（特别是Bruce Peninsula和Huron湖）中评估传统领土累积效应时的实施。 该地区已经建立了累积压力源的梯度。 这项工作将以这些知识为基础，以检验以下假设：筹款食品网络结构随着累积压力而可预测的。 因此，该研究计划有望开发有意义的指标，以与在其传统领土上具有既定环境管理记录的原住民合作量化累积效应。
