Research

Research in my laboratory focuses on the role of hydrodynamics and larval behavior in determining the spatial distribution of invertebrates in aquatic systems. Though often poorly understood, flow can be one of the most important environmental factors determining these distributions.

Currently, we are studying larvae of the black fly Simulium tribulatum. Relying on fast flow for food, safety from predators, and transportation, this aquatic life-stage of a terrestrial fly is particularly sensitive to hydrodynamic conditions in its stream habitat. Recent work has determined that the use of silk threads, similar to those produced by spiders, can influence how these larvae are transported downstream. These threads not only increase their ability to settle in regions of preferred fast flow, but may also facilitate emigration from regions with unsuitably slow flow. Future research will determine how the silk is produced, used, and under what conditions it is most effective.

In a related study, my students and I are working to understand how differences in the shape and arrangement of objects that make up the streambed can affect a larva‘s ability to settle. In both the field and in the laboratory, flow probes, video analysis and a specialized flume allow us to quantify the conditions under which larvae settle, and determine how much an individual‘s behavior can influence that process. These projects will allow us to predict how changes in the natural environment will affect invertebrate populations.
