Habitat associations of riparian beetles (Coleoptera) at Big Beaver Creek Research Natural Area, North Cascades National Park, Washington

Creator:: LaBonte, James R.
Abstract:: Beetle diversity and habitat associations of five prevalent riparian plant communities were examined along the lower reaches of Big Beaver Creek Research Natural Area, North Cascades National Park, Washington. These communities were defined by dominant tree species, and included Alder Swamps, Cedar-Hemlock Forests, Douglas-fir Forests, Gravel Bars, and Willow-Sedge Swamps....

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. Monitoring is a complex task that requires a variety of abiotic and biotic...

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...

The Miridae (Hemiptera : Heteroptera) associated with noble fir, Abies procera Rehd

Creator:: Cooper, G. M.
Abstract:: The Miridae, or plant bugs, associated with noble fir, Abies procera Rehd., are discussed. Thirty six species of the Miridae were collected from noble fir. Twenty five of these species are considered only "visitors" to noble fir. The study does not deal with these species. Noble fir is a host...

A revision of the genus Notiphila Fallén (Diptera:Ephydridae) from America north of Mexico

Creator:: Mathis, Wayne N.
Abstract:: The North American species of the shore fly genus Notiphila Fallen were taxonomically revised. Over 13,000 specimens were examined from throughout the Nearctic Region and information relating to the biology of many species occurring in the West was gathered from both field and laboratory studies. Previously used characters were reevaluated;...

A systematic study of the genus Phytocoris Fallén (Heteroptera:Miridae) in western North America

Creator:: Stonedahl, Gary Michael
Abstract:: The western Nearctic species of the genus Phytocoris Fallen were taxonomically revised. Over 15,000 specimens were examined. Information concerning host plant associations and distributions was compiled and summarized for use by future researchers. External morphological features and characters of the male genitalia were used to distinguish species. The genital tubercles...

A revision of the black grass bug genus Irbisia Reuter (Heteroptera:Miridae)

Creator:: Schwartz, Michael David
Abstract:: The black grass bug genus Irbisia Reuter was revised. Over 18,000 specimens were examined and information concerning the biology, host plant and distributional relationships of the species was compiled. In addition to external characters, the male claspers and vesica, and the female dorsal libiate plate of the bursa copulatrix and...

Abundance and community composition of arboreal spiders : the relative importance of habitat structure, prey availability and competition

Creator:: Halaj, Juraj
Abstract:: This work examined the importance of structural complexity of habitat, availability of prey, and competition with ants as factors influencing the abundance and community composition of arboreal spiders in western Oregon. In 1993, I compared the spider communities of several host-tree species which have different branch structure. I also assessed...
