Areas of Interest
Evolutionary Ecology, Effects of Fragmentation on the Genetics of Populations, Biogeography, Reproductive Strategies, Parthenogenesis, Conservation and Environmental Issues
The field of evolutionary ecology encompasses the fields of ecology, evolution and genetics. Our work involves both field and laboratory research, often utilizing molecular analyses of mitochondrial DNA and protein allozymes. Specific areas of current interest are:
Conservation Genetics. We assay genetic diversity of isolated populations that are often rare/endangered. Current projects include research on small mammals (mice, voles, shrews and flying squirrels) and salamanders which are found in the spruce-fir forests crowning the Southern Appalachians, and work on Galápagos cacti and bird populations.
Life-history and Reproductive Strategies. We are interested in how organisms adapt to their environment and the trade-offs that often occur in reproduction and lifespan. The majority of this work has occurred using the brine shrimp Artemia as the model organism and has involved laboratory and field work, especially in the Mediterranean region where parthenogenetic (all-female) populations of Artemia occur.
