Ecological genomics of aquatic invasions

由于栖息地遭到破坏、过度开发和污染加剧，淡水生态系统的物种丧失速度正在加快。该研究综合了进化、生态、毒理学、基因组的观点，并将水蚤作为一种模式生物，探讨了水蚤种群对多种应激源的耐受性进化到何种程度。将在各种诱变环境下进行长期突变积累试验，并对受污染和未受污染生境进行毒性试验和种群遗传学研究。这种综合方法将为淡水生态系统中多种压力源的研究提供新的资源，并为水生生态系统健康的多学科合作研究和培训提供独特的机会。

Freshwater ecosystems are experiencing an accelerated rate of species loss due to habitat destruction, over-exploitation and increased pollution. Using approaches that integrate evolutionary, ecological, toxicological, genomic perspectives and Daphnia as a model organism, the proposed research explores the extent to which populations evolve tolerance to multiple stressors. Long-term mutation-accumulation experiments under various mutagenic environments will be coupled with toxicity tests and population genetics studies on contaminated and uncontaminated habitats. This integrative approach will provide novel resources for the study of multiple stressors in freshwater ecosystems and a unique opportunity for multidisciplinary and collaborative research and training in aquatic ecosystem health.
