Wetland Ecosystem Functions

Research in a wide variety of ecosystems has shown that community structure and trophic interactions are important determinants of ecosystem function. Yet, due to an historical ecological paradigm emphasizing bottom-up control in wetlands, few studies have evaluated the importance of top-down effects in maintaining ecosystem processes. Our lab investigates this assumption by conducting field experiments relating food web structure to ecosystem processes in coastal wetland systems.

Predators and Restoration

Trophic cascades have been observed in numerous ecosystems and are known to have positive impacts on restoration outcomes. Yet, the role that trophic cascades and predators play in facilitating the recovery of coastal wetland ecosystem properties relative to bottom-up factors is unclear. Here, we examine the role that predators play across various contexts to help inform conservation and restoration practice.

Mangroves and Traditional Ecological Knowledge

Over the last 15 years, studies have increasingly shown the importance of top-down factors in regulating coastal wetland ecosystems. However, these studies overwhelmingly occur in salt marshes with very few exploring the role of consumer species and trophic dynamics in other coastal systems, such as mangrove forests. Additionally, studies with direct conservation applications rarely consider the role of traditional ecological knowledge and local environmental stewardship practices in maintaining these systems. Thus, our lab addresses this ecological knowledge gap for mangrove forests and incorporates the cultural values and environmental stewardship practices of the local communities affected by these efforts.

Global Change Impacts on Coastal Ecological Communities

Global change stressors are altering the structure of ecological communities with significant implications for the functions and services that ecosystems provide. Coastal zones are particularly susceptible to such stressors, yet our collective understanding of the long-term effects of global change on these systems is limited. To better understand these effects and develop comprehensive mitigation strategies, the ICL is in the early stages of creating a research program focusing on global change impacts, including nutrient enrichment, climate change, and pollution, on coastal ecological communities across various temporal and spatial scales.
