Our lab works at the interface of ecology, behavior, evolution and conservation biology. The common theme uniting our diverse research projects is how environmental conditions, including both social and ecological environment, shape animal behaviors like mating strategies, foraging ecology, and expression of signals. Here, we provide overviews of our major lines of research.

Plant-animal interactions

In the tropics, most plant species depend upon animals to disperse their pollen and seeds. Our lab uses molecular analyses, field data and experiments to test how the behavioral ecology of animal dispersal vectors shapes the ecological and genetic structure of plant communities.

Sexual selection and mating systems

Sexual selection, the competition for access to mates, is one of Darwin’s great contributions to our understanding of the natural world. Our lab explores how factors like social environment, ecological environment, and phylogeny determine variation in male and female signals and behavior, and what the consequences are for mate choice and survival.

Gulf Coast ecology

Tulane’s position in southern Louisiana presents unparalleled opportunities to pursue research questions of both broader ecological relevance and considerable local interest. The Gulf of Mexico remains an imperiled region as a variety of natural and anthropogenic effects continually threaten to degrade the marine ecosystem. Within the New Orleans city limits, residents and city officials struggle to respond to a suite of environmental challenges, both natural and man-made. Our lab addresses these issues through two research projects. One focuses on the foraging ecology of the brown pelican (Pelecanus occidentalis), using GPS telemetry to collect high-resolution movement and foraging data to better understand foraging ecology and effects of habitat restoration. A second project, based New Orleans, asks how exposure to lead impacts health and behavior of a common songbird, the northern mockingbird Mimus polyglottos. Click here to find out more..

Conservation biology

The tropics are home to more species of animal and plant than anywhere else on the planet, and many of these species are poorly known and/or threatened with extinction. Because we work primarily in the tropics, a core value of this lab is that our scientific research should contribute to conservation of biodiversity when possible. For this reason, our research goals include the basic biology, natural history, and conservation requirements of poorly known and endangered species. Click here to find out more…
