项目摘要

The project aims at the development of an improved understanding of how human-induced changes in Arctic freshwater ecosystems, such as climate change and resource development, may impact the health of northern freshwater resources and the provision of ecosystem services such as sustainable fisheries. The work will establish baseline studies of the structure, function and diversity of the Lake Greiner watershed, Victoria Island Nunavut, from its lowest trophic levels (micros, algae, plankton) to its upper trophic levels (fish) to describe how the functioning and structure of aquatic ecosystems support the production of juvenile fishes and the diversity other resident organisms and the habitats upon which the health and sustainability of fisheries ultimately depend. The work will involve a multi-disciplinary team of researchers from across the country and will expand beyond simple study of lake ecosystems to include landscape level attributes of the watershed such as tributary streams that serve as important rearing and connectivity habitats for fish. The work will establish and validate monitoring protocols for aquatic ecosystems in the north, thereby providing tools to government agencies for the continued routine monitoring of the systems and a means by which the significance of the accumulation of future ecosystem impacts (e.g., climate change, resource development) may be determined. The work will incorporate local ecological knowledge to connect northerners to the discipline of scientific assessment and provide them with the necessary access to the science need to aid them in the local management of aquatic resources. Finally the research work will link Canadian science to the larger international set of initiatives aimed at improving understanding of Arctic aquatic ecosystems at a global scale, thereby helping to enhance Canada's reputation for Arctic science.

该项目旨在发展对人类引起的北极淡水生态系统变化（例如气候变化和资源开发）如何影响北部淡水资源的健康以及提供可持续渔业等生态系统服务的健康。这项工作将建立对维多利亚岛Nunavut湖水分水岭的结构，功能和多样性的基准研究取决于。这项工作将涉及来自全国各地的一个多学科研究人员团队，并将不仅扩展对湖泊生态系统的简单研究，包括流域的景观水平属性，例如为鱼类的重要饲养和鱼类的连通性栖息地。这项工作将建立并验证北部水生生态系统的监测协议，从而为政府机构提供对系统的持续常规监控的工具，以及可以确定未来生态系统影响（例如，气候变化，资源开发）的重要性的手段。这项工作将结合当地的生态知识，以将北方人与科学评估的学科联系起来，并为他们提供必要的科学访问，以帮助他们进行当地的水生资源管理。最后，研究工作将将加拿大科学与更大的国际倡议联系起来，旨在在全球范围内提高对北极水生生态系统的了解，从而有助于提高加拿大在北极科学方面的声誉。
