Abstract: Among the many pressures that marine organisms face, intense competition and predation have contributed to the evolution of chemical defenses and the ability to sense chemical cues. Chemical ecologists have long sought to understand the identities, functions, and consequences of these compounds in the marine environment.  However, traditional approaches to connect naturally occurring chemical compounds with ecological outcomes…

Abstract:  Microbial sulfur metabolism plays a critical role in the transformation of organic carbon compounds and nutrients in the environment, human health and disease, and drives key planetary biogeochemical cycles. Our current knowledge of the microbial ecology associated with this key element is primarily based on single gene- and cultivation-based studies that provide no reliable information on comprehensive microbial metabolism and…

Annette Hynes will be speaking at the River Basin Center Third Wednesday Synposium on Wednesday, April 18th at 4:00 p.m. The title of her talk is “Modeling Ecosystem Metabolism in Coastal Estuaries.” Refreshments will be provided.

Summary: The goal of this work is to investigate growth and production dynamics of the most dominant salt marsh grass in the southeastern United States, Spartina alterniflora, including documenting the non-structural carbohydrates pool and presenting translocated biomass between above- and below-ground tissues in S. alterniflora during several phenological periods.

This seminar will feature a presentation of a short video about Sylvia’s work and which prominently features the Department of Marine Science.

Please join us for Courtney Thomas’ thesis defense on November 21st at 11:30 am. She will be speaking in room 261, and the title of her talk is: “Bacterial transporters as biosensors of labile dissolved organic matter in the surface ocean.”

The influence of aerosol particles on clouds remains one of the largest uncertainties in accurately predicting the Earth’s energy balance in a changing climate system. The size and chemical composition of aerosol particles affects their radiative properties and ability to grow into cloud droplets, thus influencing the properties and lifetimes of cloud. Recent studies suggest that the presence of surface-active organics (surfactants) in these…

Dr. Toshi Urakawa is an associate professor of marine and Ecological Sciences at Florida Gulf Coast University, which is a new public university mainly focused on undergraduate study and located in Fort Myers, Florida. In Southwest Florida his research has included: the nitrogen cycle and associated microorganisms; cyanobacteria and freshwater restoration; aquaculture; conservation biology, which include smalltooth sawfish and Burmese Pythons,…
