The Influence of Riparian Habitat and Microhabitat Selection on Fish Assemblaqe Structure in the Upper John Day Basin, Oreqon

Creator:

Leitzinger, Eric J.

Abstract:

Fish assemblage structure was determined along a longitudinal gradient for three drainages in the upper John Day basin: Middle Fork, South Fork, and upper Mainstem proper. One or two tributaries in each drainage were included. Where possible, sites were paired: those with good versus those with poor riparian habitat. Detrended...

Influences of riparian canopy on aquatic communities in high desert streams of eastern Oregon

Creator:

Tait, Cynthia K.

Abstract:

Because riparian canopy controls most energy inputs to stream ecosystems, it directly affects the structure of aquatic food webs and the ecological processes that govern interactions among trophic levels. This study addresses the interdependence among riparian canopy, benthic community structure, and the carrying capacity of high desert streams for salmonid...
