My long-term research goals include examining long-term variability in freshwater ecosystems in response to human-influenced and natural stressors. In Arctic systems, at present there are large deficiencies in our understanding of freshwater ecology. Long-term dynamics of benthic communities in freshwater aquatic systems are little known, and current knowledge of Arctic benthos is scarce and mainly derived from faunal taxonomic surveys with little or no accompanying ecological context. As the benthos are the dominant or sole energy pathway between primary producers and top trophic levels (e.g. fish and birds) in ponds and lakes, it is therefore difficult to assess or predict food-web consequences of enhanced-greenhouse climate warming in high latitude regions. This research will generate critical baseline ecological data through the limnological sampling of benthic invertebrate populations in ponds and lakes.

我的长期研究目标包括研究淡水生态系统在人类影响和自然压力下的长期变化。在北极系统中，目前我们对淡水生态学的认识存在很大的不足。淡水水生系统中底栖生物群落的长期动态鲜为人知，目前对北极底栖生物的了解很少，主要来自动物分类调查，很少或没有伴随的生态背景。由于底栖动物是池塘和湖泊初级生产者与最高营养水平（如鱼类和鸟类）之间主要或唯一的能量途径，因此很难评估或预测高纬度地区温室气候变暖加剧对食物网的影响。本研究将通过池塘和湖泊底栖无脊椎动物种群的湖沼学采样产生关键的基线生态数据。
