Romi Burks

Professor of Biology


Areas of expertise
Aquatic ecology, wetland science, apple snails, invertebrate biology

I am an aquatic ecologist interested in how organisms interact within and impact shallow lakes and ponds. My graduate work focused on looking at predator-avoidance behaviors in an important aquatic herbivore, Daphnia, that influences whether lakes exist in a clear or turbid state.

Since my arrival at Southwestern, my lab has been taken over (somewhat literally!) by an exotic, invasive apple snail, Pomacea maculata (formerly P. insularum). We have been studying this snail for 8 years now and still have a lot to learn. Advances in the field have been happening faster than we can investigate. For the most recent work on invasive apple snails, I recommend this great new scientific blog (Snailbusters).


Receiving my Ph.D. in the lab of noted exotic species authority Dr. David Lodge at the University of Notre Dame has helped me switch my current research emphasis to questions associated with invasion biology. In particular, I collaborate with student researchers to investigate multiple aspects of basic life history of this new invader. In addition, the work has expanded to include an international collaboration in Uruguay where native apple snails occur.

In addition to lab alumni and current students, collaborators on apple snail research include Mariana Meerhoff (email) and colleagues in Uruguay, Mark Kramer (email) at Armand Bayou Nature Center and Ken Hayes (email) and colleagues in Hawaii (for molecular IDs).

Our current research efforts focus on:

  1. Understanding oviposition behavior of invasive apple snails
  2. Estimating hatching efficiency of egg clutches and their role in population dynamics
  3. Investigating how predators of both eggs and hatchlings could interact with applesnails
