Biography

Dr. Robert (Bob) F. McMahon received a B.A. degree in Zoology from Cornell University in 1966 and a Ph.D. degree in Zoology from Syracuse University in 1972 with specializations in Aquatic Biology and Malacology.  He joined the faculty of the Department of Biology at The University of Texas at Arlington in 1972 where he retired as Professor of Biology and Dean of the Honors College in February 2009.  After retiring, he was appointed Professor Emeritus at UT Arlington where he continues his funded research on the biology and macrofouling control of invasive nonindigenous aquatic invertebrates, particularly zebra and quagga mussels, Asian clams, and apple snails.  He has published over 135 research papers and treatise chapters on the biology, ecology, and physiology of freshwater and marine invertebrates.  Of these, over 50 publications have dealt with aspects of the biology and control of invasive aquatic species.  His invasive species research has been has been funded by the US Fish and Wildlife Service, US Army Corps of Engineers Water Ways Experiment Station, State of Texas, and electric power and chemical industries.  He presently serves on the Western Regional Panel on Aquatic Nuisance Species, the Gulf and Southern States Panel on Aquatic Nuisance Species and has just completed a six-year term on the Federal Invasive Species Advisory Committee where he served as a member of the Steering Committee and the Early Detection-Rapid Response and Prevention Subcommittees.  He presently houses the 100th Meridian Initiative to prevent invasive species from spreading to the western states including its website in his laboratory at The University of Texas at Arlington.  Dr. McMahon has been active as an independent consultant on the biology and control of invasive aquatic molluscs for the electric power, potable water and biofouling control industries among others since 1983.

Research and Expertise

  • physiological ecology and population bioenergetics of freshwater and marine invertebrates
    My main research interests focus on the physiological ecology and population bioenergetics of freshwater and marine invertebrates, particularly gastropod and bivalve mollusks. My research areas include the biology and control of nonindigenous aquatic invertebrates such as zebra mussels and Asian clams, the effects of climatic warming including thermal effluents on the energetic allocation patterns of aquatic invertebrates, physiological responses of marine and freshwater invertebrates to environmental stress, the physiological basis of zonation in intertidal marine invertebrates, development of environmentally sound nonchemical controls for invertebrate macrofouling of raw water systems and the analysis of potential human vectors for transport of aquatic invasive species between isolated drainage systems.
