Research Interests:
I am studying how the availability of nutrients and energy influences the biodiversity of cave ecosystems. Specifically, I am interested in how the quantity and quality of allochthonous inputs into caves support the obligate cave species that depend on these resources. I am also interested in the stoichiometry of cave arthropods (that is, their chemical composition, namely C: N: P), and it’s relationship to cave adaptation. Many of the cave-adapted life history strategies may be correlated with changes in body stoichiometry, such as slow growth and thin cuticles (associated with low P and N, respectively). I will test this hypothesis through experiments both in the field and in the laboratory. I suggest that typical cave-adapted traits such as slow growth rates and thin exoskeletons, which classically have been interpreted as the result of relaxed selection pressures or the accumulation of neutral mutations, may be alternatively interpreted as adaptations to the unique stoichiometric challenges of cave environments.

Location of Research:
Greenbrier County, West Virginia.
