Brief Autobiograhical Statement
I am a behavioral ecologist with a Ph.D. (1995) in Environmental and Evolutionary Biology from The University of Louisiana, Lafayette (formerly, The University of Southwestern Louisiana). My dissertation is entitled, Variation in the Life History and Sociobiology of a Territorial Salamander. In 1991, I received an M.S. in Biology, also from The University of Louisiana, Lafayette. My thesis is entitled, Territorial Conflicts of Tail-Autotomizing Salamanders: Males Play Asymmetric Games. My undergraduate degree is a B.S. in Zoology (1988) from the University of Florida. My teaching interests are in the areas of Research Methods, Animal Behavior, Animal Physiology, Zoology, and Ecology.
Research Interests and Research in Progress
My research interest is broadly in the area of behavioral ecology. More specifically, I have combined laboratory and field studies to investigate (1) factors that influence the expression of aggressive behavior, such as body condition, body size, resource availability, and prior experience in territorial salamanders, (2) the modes by which these salamanders communicate and obtain information related to body size and condition, (3) the relationship between aggression and hormone levels, such as testosterone, (4) trade-offs associated with territorial advertisement and energy acquisition, (5) the relationship between social interactions and population distribution in natural habitats, (6) the nocturnal activity patterns of these salamanders, and (7) environmental conditions and perturbations which may alter the distribution and activity of these salamanders. Primarily, I have conducted studies using lower vertebrates, particularly reptiles and amphibians. Most frequently, I have studied the terrestrial red-backed salamander, Plethodon cinereus; a species that is abundant in mature, eastern forests throughout North America.

Opportunities for Student Research
There are many opportunities for students to conduct research under my direction, and I am currently seeking motivated students interested in behavior and ecology. Students may either conduct their own research, under my direction, or participate in one of my ongoing projects. I am interested in working with students during the regular school year and/or during the summer. Limited funding is available through the College and the Department of Biology for undergraduate research.
Below are some examples of ongoing research projects in which students may wish to become involved.
* I am investigating the relationship between testosterone and aggressive behavior in territorial residents and intruders after short-term and long-term aggressive interactions. Prior research indicates that testosterone levels drop rapidly in intruders that invade the territory of a resident and are involved in agonistic interactions. It is unknown why this may occur, or the effect that low testosterone levels may have on aggression in intruders
* Red-backed salamanders communicate ownership of territories by depositing chemical cues on the substrate of their territories. Intruders, entering these territories, obtain information about the body size and body condition of the territorial residents. The information obtained influences the intruder?s aggressive response. More studies are needed to determine the types of information intruders are obtaining about residents and how such information influences their behavior. Additionally, in collaboration with Dr. Michael Miller, students may examine the chemical makeup of the pheromones that are deposited on the substrate and the information these chemicals provide to intruders.
* Red-backed salamanders also mark territories using fecal pellets (presumably there are chemical cues in these fecal pellets). By expelling fecal pellets before all the nutrients are extracted, salamanders seem better able to attract females into their territories and perhaps better mark territories. However, this is at the expense of energy acquisition. Currently, I am studying some of the circumstances under which salamanders trade off energy and nutrients for territory defense.
* Red-backed salamanders produce sound when in close proximity to other salamanders. The function of these sounds has not yet been identified. This area of research is wide-open and provides some basic research into communication via sound.
* Salamanders are nocturnal but may use vision for foraging and during territorial contests. Ongoing research, with Dr. Bryant Buchanan, is currently examining the visual capabilities of these salamanders and the effect of light pollution (that is, excess light produced by humans) on the aggressive behavior and nocturnal activity patterns of the red-backed salamander.
