Dr. Ivan Arismendi and grad student Francisco Tinoco Pickens (OSU Fisheries and Wildlife) simulated a summer temperature regime using programmable diel temperature cycles and different degrees of changing pool-depth. 

Summer stream flow in Western Oregon is an important aspect of habitat quality for coastal Giant Salamander (Decamptodon tenebrosis) and coastal Cutthroat Trout (Oncorhynchus clarkii clarkii).  These are some of the most numerous vertebrate animals in our local headwater streams and they face increasing environmental pressures.  For example, the earlier occurrence of low stream flow in summers is causing these species to face exposure to warmer temperatures as stream habitat fragments into isolated pools. 

The study investigated intraspecific and interspecific behavior such as competition and aggression using video camera observations as well as their survival under varying environmental conditions.
