Biography

Jack McLaren is a PhD researcher in Phaedra Budy's Fish Ecology Laboratory at Utah State University. He studies how nutrients affect aquatic vegetation and the maintenance of trout habitat in the Henry's Fork of the Snake River.

Teaching Interest

Jack's teaching interests include the interface of policy and fisheries, in particular the role of recreational fishing and non-profits in fish conservation and policy. Aquatic ecology, limnology, and stream ecology. He is currently teaching Fish Diversity & Conservation.

Research Interest

Jack's research efforts focus on fish habitat, fishery production, and the creation and maintenance of salmonid habitat. This expands to process-based creation and maintenance of fish habitat, regime shifts and feedback processes in stream ecosystems, and planning for future human impacts on stream ecosystems including scenario planning, management, and applied research.
