Mark Brenner is a limnologist and paleolimnologist with special interests in tropical and subtropical lakes and watersheds. He uses sediment cores from lake bottoms to reconstruct the history of aquatic ecosystems and their drainage basins. These sediment profiles record information on long-term climate change and human-induced environmental impacts. The research is collaborative and multidisciplinary, involving several areas of expertise, including palynology, elemental analyses, nutrients, stable isotope geochemistry, microfossil analysis, and radiometric dating. Mark has worked on research projects supported by NSF, NASA, USGS, ICDP, and the Florida Water Management Districts. He has done fieldwork in Mexico, Guatemala, Bolivia, China, Cambodia, Haiti, Ecuador, Dominican Republic, Venezuela, and Florida.Mark?s research has focused on several general topics: 1) historical trophic state changes in Florida lakes, 2) paleoecology of the Maya region (Mexico and Guatemala), 3) paleoclimate of the Yunnan Plateau, China, 4) environmental history of the Bolivian Altiplano, 5) history of El Ni?o, 6) 210Pb dating, and 7) bioaccumulation of 226Ra. Mark currently serves as Director of UF?s Land Use and Environmental Change Institute (LUECI), an interdisciplinary center that has laboratories dedicated to GIS/Remote Sensing, and analysis of sediment cores from lacustrine, marine, and wetland sites (Florida Institute of Paleoenvironmental Research).
