The objective of this three-segmented research program is to assess the future provision of ecosystem services of Eastern Canada's salt marshes and the intertidal waters of the NW Atlantic in the context of human legacies, i.e., drainage for agriculture, nutrient enrichment, greenhouse warming and associated sea level rise (SLR). With the exception of local drainage, these perturbations are a legacy of land management and industrial activity worldwide. They will persist even if society is convinced to control the causes. "Ecosystem services" is a term used to denote the set of ecosystem functions that includes those with broad benefit to society, beyond the conventionally considered consumptive uses. For instance, tidal salt marshes serve as sedimentary sinks for carbon and pollutants (e.g., trace metals) and have low greenhouse gas emissions (compared to freshwater wetlands), as well as the more direct benefits of marsh plant production supporting coastal fisheries and providing habitat for wildlife. Specifically, my research will:  1) evaluate the response of marsh vegetation and marsh elevation to nutrient increases; 2) examine the process of recovery of marshes once reclaimed for agriculture to assess the potential value of deliberate restoration efforts; and 3) determine if global warming will cause shifts in the distribution of important plant and animal species along the Atlantic coast of North America.

这三个部分的研究计划的目标是评估未来提供的生态系统服务的加拿大东部的盐沼和潮间带沃茨的西北大西洋的背景下，人类遗产，即，农业排水、养分富集、温室效应和相关的海平面上升（SLR）。除了当地的排水系统外，这些扰动是世界各地土地管理和工业活动的遗留问题。即使社会确信能够控制这些原因，它们也会持续存在。“生态系统服务”一词用来表示一套生态系统功能，其中包括那些对社会具有广泛惠益的功能，而不只是传统上认为的消费用途。例如，潮汐盐沼作为碳和污染物的沉积汇（例如，此外，沼泽湿地还具有低温室气体排放量（与淡水湿地相比），以及支持沿海渔业和为野生动物提供栖息地的沼泽植物生产的更直接效益。具体来说，我的研究将：1）评估沼泽植被和沼泽海拔对营养增加的反应; 2）检查沼泽恢复的过程，一旦开垦用于农业，以评估有意恢复工作的潜在价值; 3）确定全球变暖是否会导致重要的植物和动物物种分布的变化沿着北美大西洋海岸。
