Influence of channel constraint on primary production, preiphyton biomass, and macroinvertebrate biomass in streams of the Oregon Coast Range

Creator:

Zucker, Steven J.

Abstract:

Differences in primary production and periphyton and macroinvertebrate biomass between pairs of constrained (valley floor width of less than twice the active channel width) and unconstrained reaches were investigated in Elk River and four tributaries in southwest Oregon. In August 1991, macroinvertebrates were sampled from individual cobbles, and rocks were...

Influences of clearcut logging on macroinvertebrates in perennial and intermittent headwaters of the Central Oregon Coast Range

Creator:

Banks, Janel

Abstract:

This research was designed to broaden the understanding of how timber-harvest affects aquatic macroinvertebrates in perennial and intermittent headwater streams. This study compared emergent and benthic macroinvertebrate assemblages from 20 headwater streams in the central Oregon Coast Range that varied by harvest condition and flow duration. Through comparison of the...
