Matthew O'Donnell

Matt is a Research Ecologist at the USGS Eastern Ecological Science Center at the S. O. Conte Research Laboratory in Turners Falls, MA. 

Matt's research focuses on factors that influence population persistence of stream salmonids. In particular, Matt is examining the importance of coldwater refugia, thermal acclimation, and adaptation as a possible mechanisms for brook trout to persist in warming streams. In the field, he leads a project where wild brook trout are implanted with temperature recording tags to determine what water temperature fish actually experience. In the lab, he leads experiments where brook trout are being reared under ambient and increased thermal regimes for successive generations to examine the potential scope for thermal acclimation within generations and adaptation across generations.
