Research Interests.:Updated:. March 8, 2010
The primary focus of my research as a participant in the Aquatic Research Center (ARC) at CSU-Pueblo is to elucidate how biotic and abiotic factors affect the biological health and ecological balance in riverine and lacustrine habitats of Colorado. During the past six years our ARC team has focused our research efforts almost entirely on the Fountain Creek Watershed from Monument and Green Mountain Falls to Pueblo, CO. Five major studies have been or will shortly be completed: E. coli concentrations and distributions, Ceriodaphnia toxicology, Hygrohypnum (bryophyte) mercury/selenium bioaccumulation, chironomid-species community structure, and resident fish/toxic metals bioaccumulation. We have also concentrated our studies on selected organic compounds in the Fountain Creek system that have potential impacts on human health, as well as on that of other vertebrates and invertebrates. Pueblo Reservoir and the Lower Arkansas River are also studied monthly for invasive species, their occurrence, and abundance.
