Melissa’s research interests include how pelagic, benthic, and vegetated habitats of coastal ecosystems support functions of nutrient cycling, trophic dynamics of food webs, and carbon sequestration, especially under the influence of nutrient enrichment, climate change, and restoration.
Melissa uses new and existing short- and long-term field observations, statistical analyses, and ecosystem models at the landscape level to answer ecological research questions and to meet the urgent needs of coastal managers. Melissa enjoys leading collaborative and interdisciplinary projects that generate information to inform management and policy decisions.

A model of the spatiotemporal dynamics of soil carbon following coastal wetland loss applied to a Louisiana salt marsh in the Mississippi River Deltaic Plain
The potential for carbon sequestration in coastal wetlands is high due to protection of carbon (C) in flooded soils. However, excessive flooding can result in the conversion of the vegetated wetland to open water. This transition results in the loss of wetland habitat in addition to the potential loss of soil carbon. Thus, in areas experiencing rapid wetland submergence, such as the Mississippi Ri
Tradeoffs in habitat value to maximize natural resource benefits from coastal restoration in a rapidly eroding wetland: Is monitoring land area sufficient?
Louisiana contains nearly 40% of estuarine herbaceous wetlands in the contiguous United States, supporting valuable ecosystem services and providing significant economic benefits to the state and the entire United States. However, coastal Louisiana is a hotspot for rapid land loss from factors including hurricanes, land use change, and high subsidence rates contributing to high relative sea-level
Long-term carbon sinks in marsh soils of coastal Louisiana are at risk to wetland loss
Coastal marshes are essential habitats for soil carbon accumulation and burial, which can influence the global carbon budget. Coastal Louisiana has extensive marsh habitats (fresh, intermediate, brackish, and saline) where soil cores were collected to a depth of 100 cm at 24 sites to assess long-term carbon accumulation and burial rates. Select soil depth intervals were analyzed for bulk density,
Relationships between salinity and short-term soil carbon accumulation rates form marsh types across a landscape in the Mississippi River Delta
Salinity alterations will likely change the plant and environmental characteristics in coastal marshes thereby influencing soil carbon accumulation rates. Coastal Louisiana marshes have been historically classified as fresh, intermediate, brackish, or saline based on resident plant community and position along a salinity gradient. Short-term total carbon accumulation rates were assessed by collect
Direct and indirect controls on organic matter decomposition in four coastal wetland communities along a landscape salinity gradient
Coastal wetlands store more carbon than most ecosystems globally. As sea level rises, changes in flooding and salinity will potentially impact ecological functions, such as organic matter decomposition, that influence carbon storage. However, little is known about the mechanisms that control organic matter loss in coastal wetlands at the landscape scale. As sea level rises, how will the shift from
