Assessing Cumulative Ecological Effects Development

项目摘要

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是环境管理中最重要但最棘手的问题之一。原住民特别强调了这个问题，他们担心在其传统领土上进行的多项开发，这些领土是加拿大重要的土地基础。量化累积效应的测量必须反映此类累积压力源的长期且广泛的影响。食物网生态学的最新进展已经确定了对于我们所依赖的生态系统的维持和稳定运作至关重要的生态系统结构。具体来说，强调了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，而面对人类压力必须维持的正是这些结构。该研究计划的目标是测试此类测量的实施情况，以评估索金奥吉布威国家传统领土（特别是布鲁斯半岛和休伦湖）的累积效应。该地区的累积压力梯度已经确定。这项工作将建立在这些知识的基础上，检验基本食物网结构随累积压力可预测变化的假设。因此，该研究计划承诺与在其传统领土上拥有良好环境管理记录的原住民合作，开发有意义的指标来量化累积效应。
