Life-history evaluation of Yellowstone cutthroat trout in Spread Creek, Wyoming, with specific linkages to regional climate change and invasive species


June 2012 - June 2014


In order to effectively manage native salmonid populations in the face of climate change, linkages between trout and their environment and how these relate to interactions between climate and the physical attributes of the watershed must be understood. This research will address the following question: How do interactions between climate and physical attributes of the watershed influence the spatial and temporal variation in life history patters, movement, and population dynamics of Yellowstone cutthroat trout?
