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.

这个由三部分组成的研究计划的目标是在人类遗产的背景下评估加拿大东部盐沼和西北大西洋潮间带水域的生态系统服务的未来提供，即农业排水、营养富集、温室变暖和相关的海平面上升（SLR）。除了当地排水系统之外，这些扰动都是全球土地管理和工业活动的遗留问题。即使社会确信能够控制其根源，它们仍将持续存在。 “生态系统服务”是一个术语，用于表示一系列生态系统功能，其中包括那些除了传统上认为的消费用途之外对社会具有广泛利益的功能。例如，潮汐盐沼作为碳和污染物（例如微量金属）的沉积汇，温室气体排放量较低（与淡水湿地相比），沼泽植物生产的更直接好处是支持沿海渔业和为野生动物提供栖息地。具体来说，我的研究将： 1）评估沼泽植被和沼泽海拔对养分增加的反应； 2) 检查用于农业开垦的沼泽的恢复过程，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北美大西洋沿岸重要动植物物种分布的变化。
