Conservation Biology

My conservation oriented research includes a mixture of descriptive and experimental research in two ecosystems in the southeastern United States, longleaf pine savannas and mixed mesophytic hardwood forests.  Both are disturbed, fragmented, and threatened in Louisiana.

Through joint collaborations with the Louisiana State Arthropod Museum (LSAM), my group has catalogued selected moths, ants, and bees in these two habitats. Using experimental approaches, we have tested effects of management practices such as fire frequency and fire season on insect species diversity and composition. We have also addressed the effects of an exotic insect, the red imported fire ant, on species diversity of other ants and beetles.  Our descriptive and experimental work represent the first published studies on insects in longleaf pine savannas or mesophytic hardwood forests in Louisiana.

Undergraduate Research Opportunities

I am conducting research solely with undergraduates.  Our current project involves contrasting insect species richness, abundance, and feeding guilds on exotic versus native plants.  Plants of choice are native holly, yaupon (Ilex vomitoria), and an exotic, Chinese privet (Ligustrum sinense).  In the Southeastern United States Chinese privet is invading forest understories and replacing yaupon.  Changes of this magnitude in the plant community are likely to result in changes in the insect fauna.  If vertebrates feeding on these insects are selective, changes can be expected to continue up the food chain.

I am also planning to test a new environmentally friendly control for carpenter bees.  This will be a research focus in 2007 and a perfect experimental project for undergraduates.

Field Sites for Research

Louisiana and neighboring states contain numerous public and private tracts of land that are ideal sites for conducting research in conservation biology.  Visit the Research Sites link for an overview of some of these locations.
