   personal_statement: James has broad research expertise and investigates the ecological
     consequences of stressors like invasive species, climate change, and eutrophication
     for aquatic systems and specifically fish populations. There are three overall
     themes his research is split between (Invasive species, native fish ecology/conservation,
     and climate changes effects) which are all related to the conservation and management
     of aquatic species and systems.Currently, he is investigating the movement,
     behavior, and habitat use of Grass Carp, an invasive species in the Great Lakes.
     He has also conducted research in the Laurentian Great Lakes examining the ecological
     consequences of seasonal hypolimnetic hypoxia, dead zones, in Lake Erie. Specifically,
     he studied the effects (behavioral, physiological, and inter-specific) of hypoxia
     on the benthic fish assemblage of Lake Erie, while focusing on yellow perch.
     Previously, James has explored the potential effects climate change may have
     on the persistence of Cutthroat Trout in stream and lake habitats throughout
     the Southern Rocky Mountain region."
