I am currently investigating the toxicological and ecological role of Prymnesium parvum in Lake Texoma. My background is in organizing and working on lake monitoring and data collection. My interests are in zooplankton migration and spatial distribution, and predator driven fish -zooplankton interactions.

My current research with Larry Weider focuses on factors influencing the success of biological invasions, in particular microevolutionary processes vs. broad physiological tolerance to the environment. Two invasive zooplankton organisms are used as model species which have each invaded new continents across large geographical scales: Daphnia lumholtzi (Cladocera, Crustacea) in North America, and Acartia tonsa (Copepoda, Crustacea) in Europe. I am also involved in a project (with Andy Green at the Doñana Biological Station in Sevilla, Spain) on the dispersal biology of zooplankton and consequences of propagule dispersal on species and genetic diversity in temporary ponds.

My work takes functional and comparative approaches to understanding the relative importance of various mechanisms in the evolution of biological diversity, the predictability of evolution, and the formation of new species.  My empirical work centers on the evolutionary diversification of small livebearing fishes in the genus Gambusia (moquitofishes) as the focal model system.  Website: faculty-staff.ou.edu/L/Randall.B.Langerhans-1

Richard Zamor
Doctoral Student, University of Oklahoma

My research interests include most aspects of fish ecology and fish community ecology. I graduated cum laude with a B.S. in Zoology from the Unversity of Oklahoma. Following this I completed my M.S. in forest resources (with a focus on fish ecology) under Gary Grossman at the University of Georgia. This research focused on the effects of turbidity on fish foraging. For my Ph.D. with David Hambright, I am researching the toxic and lethal effects of golden algae (Prymnesium parvum) on fishes. I also enjoy anything to do with Sooner football.
