Species Interactions

An exciting theme of our research involves identifying key components of food and interactions webs. This work helps to elucidate the effects of interactions on other species through both direct and indirect pathways, and can be informative about the effects of altering the abundances of particular species within these interaction webs. Most of our efforts along this theme use experimental approaches, both in the field and the lab, but we also explore long-term datasets and use isotopic and compound specific analyses to address our questions.

 

Ongoing Research


Ontogenetic Diet Shifts

Most piscivorous fishes change their diets several times during their juvenile stages as their gape size increases and their ability to catch larger more mobile prey improves. Using a combination of stomach contents, stable isotope analysis and compound specific approaches, we are investigating the commonality of diet shifts in fishes across large geographic scales.
