Estuarine and coastal studies form the core of research activities performed by Dr. Pinckney. General areas of interest include marine ecology, microbial ecology, microalgal ecophysiology, phytoplankton-nutrient interactions, harmful algal blooms, and ecosystem eutrophication in estuarine and coastal habitats of Texas. Specific interests are centered around the ecophysiological factors and processes that influence carbon partitioning, allocation (growth), and interspecific competition in multispecies assemblages. Most of Dr. Pinckney’s work over the past 20 years has emphasized investigations of the ecophysiology of benthic and phytoplanktonic communities and their contribution to ecosystem function. Analytical approaches involve manipulative field and laboratory experiments for examining the ecological physiology and responses of microalgal communities. Current research is being conducted in local estuarine, riverine, and intertidal habitats, as well as in pelagic systems in the Gulf of Mexico and hypersaline lagoons in the Bahamas.
