Survival and development of the flat-headed fir borer in forest residues as affected by host and microclimatic conditions

Creatore:: Scott, Donald Wayne
Abstract:: The purpose of this study was to examine various host and microclimatic influences affecting the survival and development of the flatheaded fir borer, Melanophila drummondi (Kirby) in Douglas fir, Pseudotsuga menziesii (Mirbel) Franco residues. It also expands current knowledge of the biology, bionomics, life history, ecology, and biotic potential for...

Ground dwelling beetles in early and late successional forests in the western Cascades of Oregon

Creatore:: Heyborne, William H.
Abstract:: The effects of forest cutting on forested systems and the biotic components of those systems has been at the forefront of scientific research. The inventory and monitoring of biodiversity is one technique used for measuring the effects of forest management. Because bioinventory studies are expensive, indicator species are often sought...

Edge effects of clearcut harvesting on ground arthropod species composition and predator community structure in old-growth Douglas-fir forests

Creatore:: Work, Timothy Theron
Abstract:: Edge effects resulting from forest fragmentation are likely to alter the distributions and interactions of resident species. I evaluated changes in species composition, species turnover, and relative abundance of ground arthropods across replicated transects extending from regenerating clearcuts into old-growth Douglas-fir forests. Arthropods were collected from 3-August to 14-September in...

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

Creatore:: 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....

Relationships between forest-floor invertebrate distribution, movement, and microclimate under alternative riparian management practices

Creatore:: Rykken, Jessica J.
Abstract:: Headwater streams and their riparian zones are a common, yet poorly understood, component of Pacific Northwest landscapes. I sought to describe the ecological significance of headwater stream riparian zones as habitat for forest-floor invertebrate communities, and to assess how alternative management strategies for riparian zones may impact these communities. I...

Insect enemies of Dendroctonus pseudotsugae Hopk. : indentification of their immature stages and distribution in standing trees

Creatore:: Kline, LeRoy N.
Abstract:: The objectives undertaken in this study were: 1) to develop means of identifying the immature stages of the known insect predators and parasites of the Douglas-fir beetle; 2) to investigate the possible distribution, spatially and/or temporal, of the known insect predators and parasites in standing trees infested by the Douglas-fir...

Ecuadorean soil arthropod distribution in native vegetation, pasture and cropland and a potato field with and without pesticides

Creatore:: Núñez Terán, Verónica
Abstract:: In the past 10 years we have witnessed the beginnings of the study of soil ecology as a unified science, and the general realization by soil scientists, farmers, and land managers that many of the most important economic aspects of soil health are controlled by biological factors. This research focuses...

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

Creatore:: 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...
