Insects are the dominant life form on Earth, representing more than 75% of all identified species. My lab focuses on community and population ecology of aquatic insects with a focus on species that occur in mosquito-dominated container systems and pond communities. My general interests lie in understanding patterns of species richness and abundance and how species interactions, like predation and competition, affect food webs. I also am interested in understanding how the type and amount of detritus that supplies energy for container systems affects nutrient dynamics and food webs, from the basal microorganisms through to their consumers. My lab employs a variety of tools when approaching research problems, including field observations and experiments, laboratory experiments, and statistical modeling.
A multitude of animal and human diseases are vectored by adult mosquitoes, the larvae of which inhabit aquatic containers (e.g., tree holes, discarded automobile tires). Because they are relatively easy to maintain in the laboratory and obtain and manipulate in the field they are an ideal study animal for testing ecological theories related to community organization and population dynamics. Specifically, research in my lab focuses on questions related to spatial and temporal population patterns, colonization and dispersal behavior, feeding behavior as it relates to competitive interactions, nutrient and stable isotope analysis, phenotypic plasticity in response to environmental variation, and the influence of invasive species (e.g., Aedes albopictus, Culex coronator) on natives (e.g., Aedes triseriatus, Culex quinquefasciatus).

A central focus of ecology has been in understanding the factors that control the number of species within a habitat. One of my main interests has focused on understanding the factors that control species richness in small aquatic microsystems. The container systems I work in are dominated by aquatic diptera (including medically important mosquitoes), but contain a number of non-dipteran insect larvae (e.g., Coleoptera) non-insects (e.g., copepods, annelids), and microorganisms (protozoans, fungi, bacteria). In several studies I have examined the relationship between productivity, abundance, and species richness of container species.

Predaceous diving beetles
These predatory beetles, also known as dytiscids (Coleoptera: Dytiscidae), occur in various water bodies (e.g., ponds, streams, ditches) across the world. Although this family is composed of about 4,200 species world-wide, there exists little ecological knowledge about this cosmopolitan group. Larvae and adults all are predaceous, making them an important component of the aquatic food webs in which they occur.
