Thus, we provide a conceptual framework for the design and implementation of monitoring studies to understa...

Approximately 1.5 million acres of lodgepoledominated forest is already dead or dying in Colorado, the infestation is still spreading rapidly, and it is expected that in excess of 90 percent of all lodgepole forest will ultimately be killed. Dro...

The effects of constant (12, 18, and 24 C) and cyclical (daily variation of 15–21 and 12–24 C) thermal regimes on the growth and feeding of Lahontan cutthroat trout (Oncorhynchus clarki henshawi) of variable sizes were examined. Higher constant temperatures (i.e., 24 C) and more variable daily temperatures (i.e., 12–24 C daily cycle) negatively affected growth rates. As fish mass increased (fro...
