Research Interests: Landscape and community ecology;
mercury as an ecosystem contaminant.
Currently my research interests are centered on
questions involving the uptake of mercury by plants and animals from
terrestrial ecosystems. Much of my work has been in conjunction with
undergraduate and graduate students at James Madison University. We
have been looking at field situations associated with contamination of
the South River floodplain at Waynesboro, VA, as well as laboratory
models of bioaccumulation in plants and earthworms. We have looked at
translocation of Hg within plant tissues, and most recently, the role
of atmospheric dust deposition as contaminant source.
