Effects of interaction with coral reefs on evolution of fishes by Katherine Corn

Katherine is interested in the evolutionary mechanisms underlying the diversity of vertebrates. Her research integrates macroevolution and biomechanics to understand how transitions in feeding mode affect the morphological diversity of fishes.

ABSTRACT

Katherine’s research integrates phylogenetic comparative methods, biomechanics, and her love of fishes to explore the macroevolutionary consequences of major ecological transitions. Suction feeding is the dominant mode of prey capture in aquatic vertebrates, but some of the 35,000 species of fishes rely on biting feeding modes, where the jaws make contact with the substrate during prey capture. Katherine’s research measures the implications of transitions to biting on cranial mobility of fishes. She uses cutting-edge phylogenetic comparative methods and the largest vertebrate body shape dataset ever produced to explore how changes in feeding mode affect the evolution of body shape.
