A novel landscape ecology approach for determining microhabitat correlations and faunal patchiness in extreme environments:pilot study for the Southern East Pacific Rise at 17-18° S

Creator:: Wargo Rub, Michelle
Abstract:: Since their discovery in 1977, hydrothermal vent communities have offered scientists a unique glimpse into a world that is supported primarily by chemically derived energy rather than direct energy from the sun. Furthermore, studies of hydrothermal vent ecosystems have introduced scientists to amazing animals that have successfully adapted to living...

Free-choice family learning in a bilingual marine science program : a qualitative investigation of interactions and long-term impacts among Mexican-descent families

Creator:: Schmoock, Heidi I.
Abstract:: In the past most research of family learning in informal science learning environments has included limited diversity among participants considering ethnic, cultural, and social economic status. The diversity seen in informal learning environments such as museums does not typically reflect that of the general population. Therefore, in order to foster...

Behavioral responses of Rocky Mountain Elk (Cervus elaphus) to recreational disturbance

Creator:: Naylor, Leslie M.
Abstract:: I measured responses of free-ranging Rocky Mountain elk (Cervus elaphus) to recreational disturbance at Starkey Experimental Forest and Range, Oregon from April to October, 2003 and 2004. Resting, feeding, and travel activities of 13 cow elk were recorded at 5-minute intervals using Actiwatch™ motion sensors. Elk were subjected to four...

Limiting copper loss from treated wood in or near aquatic environments

Creator:: Mitsuhashi Gonzalez, June M.
Abstract:: Copper migration from treated wood has created concerns within the environmental community because of the potential effects of this heavy metal on aquatic organisms. Migration can be limited, to some extent, by more controlled treatments and by post-treatment processing, but these actions cannot completely overcome the problem. An alternative approach...

Predators associated with hemlock woolly adelgid (Hemiptera: Adelgidae) infested western hemlock in the Pacific Northwest.

Creator:: Kohler, Glenn R.
Abstract:: The hemlock woolly adelgid, Adelges tsugae, is causing widespread mortality of eastern hemlock, Tsuga canadensis, in the eastern United States. In the West, A. tsugae causes negligible damage to western hemlock, Tsuga heterophylla. Host tolerance traits and presence of endemic predators may be contributing to the relative tolerance of western...

The marine geomorphology of American Samoa : shapes and distributions of deep sea volcanics

Creator:: Roberts, Jed T.
Abstract:: The geologic processes at work in American Samoa have long been a point of scientific debate. Of its numerous volcanic formations, few breach sea level, leaving an enormous proportion of their mass unavailable to traditional observation. This study aims to describe the deep sea geomorphology of American Samoa through compilation,...

'Hysterical preservationists' and 'gouge-and-run bulldozer boys' : the land-use controversy in Idaho’s White Cloud Mountains, 1968-1972

Creator:: Jensen, Erica (Erica Lyn)
Abstract:: Similar to other spectacular scenic areas in the American West, Idaho’s White Cloud Mountains have been a contested landscape since the beginning of the 20th century. Although, legislation was introduced in Congress as early as 1913 to protect the towering mountains of south-central Idaho as a national park, the issue...

Effects of estuarine circulation patterns and stress on the migratory behavior of juvenile salmonids (Oncorhynchus sp.)

Creator:: Truelove, Nathan Kobun
Abstract:: For the first objective of this thesis, we attempt to understand the role of water flow and directionality in determining steelhead (Oncorhynchus mykiss) and spring/summer and fall Chinook (O. tschawytscha) migration patterns within the Columbia River Estuary and plume by integrating recent advances in biotelemetry and environmental observation and forecasting...

Terrestrial amphibian distribution, habitat associations and downed wood temperature profiles in managed headwater forests with riparian buffers in the Oregon Coast Range

Creator:: Kluber, Matthew R.
Abstract:: Western forests have become increasingly fragmented landscapes dominated by young stands. Given that western Oregon forests largely consist of headwater systems, there is a need to better understand how headwater forest taxa and their habitats are impacted by forest management practices. Several amphibian species associated with forested headwater systems have...

Assessing the impact of temperature on grape phenolic metabolism

Creator:: Cohen, Seth D.
Abstract:: Many climatic factors influence grape berry composition including nutrient status, water availability, biotic stress, sun exposure and temperature. Previous research examined the effects of many factors listed above and much progress has been made. It is often difficult, however, to separate effects that typically confound each other, such as sun...
