Plants respond to defoliation in many different and complex ways, depending on their growth habit and form as well as the extent and duration of the defoliation. Tree crowns have been shown to be quite sensitive to disturbances such as defoliation, however quantitative relationships have rarely been developed, making the...
The variability of selected physical, chemical, and morphological
soil properties in two landtype mapping units on'the Rogue River National
Forest in southwestern Oregon was studied.
The objectives of the study were (i) to quantify soil variability
in several soil resource inventory mapping units, (ii) to explore methods
of describing soil...
This project examines the landscape of the farming community of Beagle, Oregon
prior to and during the Second World War and the effect on it due to
the construction of Camp White, a World War II training facility. The Beagle
landscape is examined through the prism of current theory that...
Fifteen species of Noctuidae (Lepidoptera) were collected in alfalfa and
peppermint in western Oregon. Seven of these species were hosts for the braconid
parasitoid Meteorus communis. The most frequently parasitized (percent) species were
Agrotis ipsilon (35.3), Dargida procincta (15.0), and Peridroma saucia (6.9). Other
species parasitized were Autographa californica (3.8)...
The known biology of Bareogonalos canadensis
(Harrington) is based on literature records of six
collections from three areas in the Pacific Northwest.
The objective of this study was to obtain fundamental
knowledge on the biology of B. canadensis, especially
its distribution, abundance, and host species, as well
as its potential...
This dissertation serves as a contribution to the study of the prehistory of the Central Desert region of Baja California, Mexico. Between 2007 and 2011, a trans-peninsular archaeological survey and excavation program―the Central Desert Early Prehistory Project (CDEPP)―was completed for a portion of the Baja California peninsula extending from the...
