Responses of a threatened cutthroat trout to an introduced, invading salmonid : ecological implications for growth, stress, and behavior

Creator:

Osborne-Gowey, Jeremiah D.

Abstract:

Recent studies suggest that competition from brook trout (Salvelinus fontinalis; EBT) may have negative effects (e.g. displacement) on Lahontan cutthroat trout (Oncorhynchus clarki henshawi; LCT). Results from these studies have failed to elucidate the responsible mechanisms and have not examined if changing environmental conditions result in competitive/subordinate role reversals. The...

Local weather, regional climate, and population dynamics of northern spotted owls in Washington and Oregon

Creator:

Glenn, Elizabeth M.

Abstract:

Since the early 1990s, declines in northern spotted owl (Strix occidentalis caurina) populations have been documented through extensive field surveys and range-wide demographic analyses. Although loss of late-successional forest has been credited as the primary cause for spotted owl population declines, environmental variation has also been shown to influence vital...
