Influence of spatial and temporal factors on plants, pollinators and plant-pollinator interactions in montane meadows of the western Cascades Range

Creator:

Pfeiffer, Vera W.

Abstract:

Montane meadows comprise less than 5% of the landscape of the western Cascades of Oregon, but they provide habitat for diverse species of plants and pollinators. Little is known about plant-pollinator network structure at these sites. This study quantified plant-pollinator interactions over the summer of 2011, based on six observations...

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...
