Robert Colombo's Vita

Research

My research focuses on how fish populations respond to anthropogenic impacts.  Specifically, I am interested in the responses of native fishes to harvest, invasive species and habitat alterations.  Most of my research focuses on commercially or ecologically important species in lotic (flowing) water system.
