The anthropogenic pressures currently applied to aquatic habitats (increased metal loads, high concentrations of nutrients, increased acidity, accelerated introduction of invasive species) can generate extreme environmental conditions that can alter the supported communities and compromise the function of these ecosystems. Evaluating the impact of multiple stressors on aquatic ecosystems is particularly challenging due to the interactions amongst sources of stress and amongst the organisms themselves as well as the complex ecological and evolutionary dynamics that follow after stress. The long-term research objective of the proposed work is to advance new, integrative approaches for the study of multiple stressors in aquatic ecosystems.

目前对水生生境施加的人为压力（金属负荷增加、营养物浓度高、酸度增加、入侵物种的加速引入）可能产生极端的环境条件，从而改变所支持的群落，损害这些生态系统的功能。由于压力源之间的相互作用和生物体本身之间的相互作用以及压力后复杂的生态和进化动态，评估多重压力对水生生态系统的影响特别具有挑战性。拟议的工作的长期研究目标是推进新的，综合的方法在水生态系统中的多重压力的研究。
