Dr. Catherine Langtimm

Dr. Catherine Langtimm is a wildlife biologist with the U.S. Geological Survey and a research associate at the Biology Department of Holy Cross College. Her work focuses on assessing population trends and estimating life history parameters for species of special concern to the U.S. Department of the Interior. Her primary research focus in the Gulf of Mexico is on the population ecology of the Florida manatee, a coastal marine mammal listed as endangered due to its small population size, degraded habitat and high mortality from collisions with boats. She is using mark-recapture statistical models to estimate annual survival rates and reproduction rates and to identify human and environmental factors that affect these rates. This information is being used by wildlife managers to assess population status and to determine management policies.
