Structure, function, and analysis of Coleoptera and Heteroptera assemblages on two species of hazelnut in Oregon

Creator:: Wetherill, Karen R.
Abstract:: The European hazelnut, Corylus avellana L., was imported into the U.S. in the late 1800's and is now grown throughout the Willamette Valley in Oregon. A native species of hazelnut, C. cornuta Marshall, is a common shrub found in forested areas of the Pacific Northwest. Foliage of both C. avellana...

The higher classification of the Hesperiidae (Lepidoptera: Hesperioidea)

Creator:: Warren, Andrew D.
Abstract:: A comprehensive tribal-level classification for the world's subfamilies of Hesperiidae, the skipper butterflies, is proposed for the first time. Phylogenetic relationships between tribes and subfamilies are inferred using DNA sequence data from three gene regions: 943 bp of cytochrome oxidase subunit I (COI) (in the mitochondrial genome), 739 bp of...

Effects of Tetranychus urticae Koch feeding injury on physiological processes in Mentha piperita L.

Creator:: DeAngelis, Jack D.
Abstract:: Studies were conducted to examine the effects of feeding injury by the twospotted spider mite (Tetranychus urticae Koch) on physiological processes of its host plant, peppermint (Mentha piperita L.). Aspects of mite-induced host plant physiological stress that were studied included: 1) effects of injury on plant-water relations; 2) photosynthesis and...

The influence of light intensity on the phytochemistry of Chrysolepis chrysophylla (Fagaceae) and the relationship to the herbivory of Habrodais grunus herri (Lycaenidae)

Creator:: Bowden, Richard I.
Abstract:: Defensive chemical and nutritive quality of young leaves were measured for 72 individual trees of Chrysolepis [Castanopsis] chrysophylla in conjunction with light intensities of two different stand types and population numbers of Habrodais grunus herri in the Cascade mountains of Oregon. Leaves were collected in the spring and leaf characteristics...

Soil arthropods in the Central Cascades : slash burning effects and biology of some species

Creator:: Estrada-Venegas, Edith G
Abstract:: Despite the recognized role of soil arthropod fauna on nutrient cycling and decomposition processes, many aspects of the effects of sylvicultural methods in forest ecosystems upon their biology remain poorly understood. The long term effects of prescribed fires on soil arthropods in forest ecosystems in the Pacific Northwest have never...

Natural enemies of native bumble bees (Hymenoptera: Apidae) in western Oregon

Creator:: Maxfield-Taylor, Sarah A.
Abstract:: Bumble bees (Hymenoptera: Apidae) are important native pollinators in wild and agricultural systems, and are one of the few groups of native bees commercially bred for use in the pollination of a range of crops. In recent years, declines in bumble bees have been reported globally. One factor implicated in...
