The seasonal occurrence and distribution of stoneflies (Plecoptera) of a western Oregon stream

Creator:

Kerst, Cary Dean

Abstract:

Plecoptera were collected from four sampling stations selected to represent a range of conditions on Oak Creek, a small woodland stream originating in the foothills of the Oregon Coast Range. The elevation of Site I was 700 ft. while the lowest site was located at 225 ft. Monthly benthos samples...

The species composition and adaptations of insects in an intermittent stream in western Oregon

Creator:

Tew, Michael Peter

Abstract:

The insect fauna of a small second order intermittent stream near Corvallis, Benton County, Oregon was studied. The species composition was determined, attempts were made to monitor migration to the stream, qualitative and quantitative benthos samples were taken, emergence was sampled, the dry stream bed was examined for forms of...

Biology and downstream drift of some Oregon Ephemeroptera

Creator:

Lehmkuhl, Dennis Merle, 1942-

Abstract:

Six species of Ephemeroptera were studied in two sample areas in Western Oregon: the Metolius River, Jefferson Co., and Oak Creek, Benton Co. The Metolius River is characterized by low fluctuations in flow and water temperatures (8-13 C); whereas, Oak Creek is characterized by large fluctuations in volume of flow...

The conversion of allochthonous material by stream detritivores

Creator:

Grafius, Edward John

Abstract:

The role of detritivores in the conversion of allochthonous leaf material in two small streams in the Cascade Range of Oregon was studied. Their importance in relation to other consumers was estimated from emergence and benthic standing crop data. Ingestion rates and efficiencies of utilization of bigleaf maple (Acer macrophyllum)...

Masters Thesis
Bioenergetics and strategies of some trichoptera in processing and utilizing allochthonous materials

Creator:

Grafius, Edward John

Abstract:

The purpose of the study was to provide quantitative information on the utilization and processing of leaves and needles by several species of caddisfly larvae. Field and laboratory studies were conducted on three species of Lepidostoma Rambur (Lepidostomatidae), from Willamette Valley and Cascade Mountain streams, and on Clistoronia magnifica (Banks)...

The ecology and production dynamics of four black fly species (Diptera:simuliidae) in western Oregon streams

Creator:

Speir, Jon A.

Abstract:

Ecological and production studies of Prosimulium caudatum Shewell, P. dicum Dyar and Shannon, Simulium arcticum Malloch and S. canadense Hearle (Diptera: Simuliidae) were made in 1971 and 1972 in three streams near Corvallis, Oregon. The purpose of the study was to characterize the biology and population dynamics of larvae, and...

Dissertation
Effects of controlled flow reductions on the insect community of an Oregon coastal stream

Creator:

Hafele, Richard E.

Abstract:

Controlled flow reductions of 75% apportioned over four two-week intervals were studied during the summers of 1975 and 1976 on the North Fork of Elk Creek, an Oregon coastal stream. The effects of reduced flows on invertebrate drift, insect benthos, and the available food for juvenile salmonids were measured. Invertebrate...

Masters Thesis
Life history studies of Cinygma integrum Eaton (Ephemeroptera : Heptageniidae) and other mayflies associated with wood substrates in Oregon streams

Creator:

Pereira, Christine Rosabelle Dolores

Abstract:

Wood debris serves an important substrate for macroinvertebrates in streams. Particle size reduction due to feeding and other activities can be an important role of the fauna in wood degradation. In this study the Ephemeroptera associated with wood were investigated, with the objective of assessing their impact in the degradation...
