Impacts of climatic change and environmental stress on northern lakes and ponds

目前的北方补充资金的建议补充了我正在进行的NSERC资助的研究活动“气候变化和环境压力对水生生态系统的影响”（NSERC发现赠款2003-2007年，2008年-提交）。它寻求更多的后勤支助，以继续开展一个项目，促进对北方偏远湖泊和池塘的长期实地调查和监测网络的发展，这些湖泊和池塘沿着一条横贯魁北克省西北部（努纳维克）、福克斯盆地地区和拜洛特岛（努纳武特）的纬度样带分布。北纬55-73度。77-85度长。W）。对选定参数的反复观察将使我们能够继续监测湖沼变化，并发现这些宝贵的北方淡水资源的趋势，以及提供基线数据，据以衡量这些脆弱的北方环境的持续变化。为这些调查和监测活动提供资金还将使我们能够更好地综合古湖沼学和新湖沼学方法（基于过程的研究），以努力提高我们对北方淡水生态系统及其生物区系对全球气候变化以及自然和人为环境压力和干扰的反应的认识。

The present proposal for northern supplement funding complements my ongoing NSERC-funded research activities on the "Impacts of climatic change and environmental stress on aquatic ecosystems" (NSERC Discovery grants 2003-2007, 2008- submitted). It seeks additional logistic support for the continuation of a project that promotes the development of a long-term field-based survey and monitoring network of remote northern lakes and ponds distributed along a latitudinal transect across northwestern Québec (Nunavik), the Foxe Basin region and Bylot Island (Nunavut) (ca. 55-73 degrees lat. N; 77-85 degrees long. W). Repeated observations of selected parameters will allow us to continue our monitoring of limnological change and detect trends in these precious northern freshwater resources, as well as provide baseline data against which to measure ongoing changes in these fragile northern environments. Funding for these survey and monitoring activities will also allow us to better integrate paleo- and neo-limnological approaches (process-based studies) in an effort to improve our understanding of the response of northern freshwater ecosystems and their biota to global climate change, as well as to natural and anthropogenic environmental stresses and disturbances.
