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

目前关于北方补充资金的提议补充了我正在进行的由NSERC资助的关于“气候变化和环境压力对水生生态系统的影响”的研究活动(NSERC发现赠款2003-2007,2008-提交)。它寻求为一个项目的继续提供更多的后勤支助，该项目促进发展一个长期的实地调查和监测网络，该网络包括分布在魁北克西北部(努纳维克)、福克斯盆地地区和比洛特岛(努纳武特)(北纬55-73度)的偏远的北部湖泊和池塘。N；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泊变化，发现这些宝贵的北方淡水资源的趋势，并提供基准数据，以衡量这些脆弱的北方环境正在发生的变化。为这些调查和监测活动提供资金还将使我们能够更好地整合古湖沼学方法(基于过程的研究)，努力增进我们对北方淡水生态系统及其生物群对全球气候变化的反应以及对自然和人为环境压力和干扰的反应的了解。

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.
