Formation and maintenance of fish assemblages in a high desert Oregon stream

Creator:

Pearsons, Todd N.

Abstract:

Considerable controversy exists about how fish assemblages are organized. I explicitly took fish movement into account while I studied the effects of disturbance, habitat complexity, and predation at different times of the summer to understand the major factors influencing assemblage structure in a high desert Oregon stream. The effects of...

From continua to patches : longitudinal patterns in the Middle Fork of the John Day River, Oregon

Creator:

Wright, Kristopher Keith

Abstract:

The Middle Fork John Day River is composed of low gradient, alluvial valley segments separated by constrained, canyon-like reaches, and has a history of multiple land-uses. These factors can alter the physical and biological structure of streams, and disrupt the longitudinal river continuum. I examined habitat, fish, macroinvertebrates, and primary...

Relations among hydrology, soils, and vegetation in riparian meadows : influence on organic matter distribution and storage

Creator:

Dwire, Kathleen A.

Abstract:

Organic matter dynamics in riparian ecosystems are largely driven by interactions among hydrology, soil, and vegetation. In two riparian meadows, northeast Oregon, I examined the hypothesis that vegetation and soil characteristics in three plant communities - defined as wet, moist, and dry meadow - were strongly influenced by hydrological and...

Riparian vegetation and abundance of woody debris in streams of southwestern Oregon

Creator:

Ursitti, Victoria L.

Abstract:

Riparian vegetation (trees > 10 cm dbh), woody debris (> 10 cm diam, > 1 m long), channel, and landform characteristics were inventoried in mature (80-150 yrs) and old-growth riparian areas (>250 yrs) selected from small tributaries of the Coos and Coquille River basins in southwestern Oregon. Basal area of...
