Riparian and adjacent upslope beetle communities along a third order stream in the western Cascade Mountain Range, Oregon

Creator:: Brenner, Gregory John
Abstract:: Monitoring wildlife habitats has become important to forest ecosystem management because it provides valuable information about the response of forests and their species to harvest practices, impacts from recreational use, conservation efforts, and natural and human-caused disturbances.

A revision of the North American species of Pactopus Leconte and Trixagus Kugelann (Coleoptera: Throscidae)

Creator:: Yensen, Arthur Eric
Abstract:: This study was undertaken to find means of separating the morphologically similar species of North American Trixagus and to bring together information on Trixagus and Pactopus. A key to separate the world's eight genera of extant Throscidae is presented for the first time. A key to the five species of...

Biology and adult variability in an Oregon population of Leptarctiacaliforniae (Walker) (Lepidoptera: Arctiidae)

Creator:: Mays, David Lee
Abstract:: Leptarctia californiae (Walker) was studied on clear and semi-forested southern slopes in the Coast Range Mountains of Benton County, Oregon. The spring of 1965 had an unusually long warm period (21 days) resulting in adult emergence approximately 25 days earlier than in the cooler spring of 1966. Peak flight activity...

Biological studies on Saldula palustris (Douglas) with emphasis on factors influencing wing pigmentation (Heteroptera:Saldidae)

Creator:: Stock, Mary Wilford
Abstract:: The life history and wing pattern variation of the intertidal shore bug, Saldula palustris (Douglas), were studied in field and experimental populations from June 1970 until February 1972.
