Notes

Scope and Content:
New and ongoing research activities and findings relevant to the goals of the FCE II proposal are reported separately by working group, below. 1. Primary Production Observational studies of long-term trends in primary production and plant community structure continue in the major community types of the FCE domain: freshwater marsh, mangrove forests and seagrass meadows. Freshwater Marsh: Long-term trends in periphyton biomass and composition at the FCE sites were combined with large-scale landscape data to produce models that predict changes in periphyton biomass, composition and nutrient content from alternative water management scenarios. Comparative international investigations continue in karstic wetlands elsewhere, including the Caribbean wetlands and Canadian alvars, and a special issue on the topic is being prepared for the Journal of Cave and Karst Science. Mangrove Forests: The response of carbon storage and net primary production of mangrove forests to hurricane disturbances was assessed through long-term observations and gas flux studies. We also investigated how carbon storage in mangrove forests responds to temperature and cold-air disturbances. We began collaborations with Tom O’Halloran (Sweet Briar College) to understand how different plant functional groups’ productivity responds to diffuse irradiance. Our carbon dynamics work involves high-resolution eddy covariance datasets, so we participated in the LTER workshop, Software tools for sensor networks (http://sensor-workshop.ecoinformatics.org/) held in May 2012. We continue to deploy sulfur hexafluoride (SF6) inert tracers to understand water and carbon flow patterns in the Shark River. Seagrass Meadows: Experimental studies in seagrass meadows explored the response of these systems to changes in pCO2, with a goal of predicting the response of seagrass meadows to environmental change. The role of seagrasses as global carbon sinks was established.
