Riparian vegetation and abundance of woody debris in streams of southwestern Oregon

Creator:: Ursitti, Victoria L.
Abstract:: Riparian vegetation (trees > 10 cm dbh), woody debris (> 10 cm diam, > 1 m long), channel, and landform characteristics were inventoried in mature (80-150 yrs) and old-growth riparian areas (>250 yrs) selected from small tributaries of the Coos and Coquille River basins in southwestern Oregon. Basal area of...

Uptake and metabolism of polycyclic aromatic hydrocarbons by the marine alga Acrosiphonia coalita

Creator:: Christensen, Kristi
Abstract:: The purpose of this research was to examine the ability of the cold water, green, marine, macroalga Acrosiphonia coalita to take up and metabolize polycyclic aromatic hydrocarbons (PAH) from seawater. Axenic suspension tissue cultures of the alga were contacted with seawater containing PAH in sealed experimental vessels. Uptake time courses...

A contextual model for the integration of LifeKnowledge curriculum into the agricultural science and technology classroom

Creator:: Crawford, Paul Wesley
Abstract:: The purpose of this study was to evaluate a contextual model for integrating lessons from the LifeKnowledge curriculum into the agricultural science and technology (AST) course content. This was measured using the National FFA Organization’s online precept indicator which is part of the LifeKnowledge 3.0 curriculum. Ninth grade students at...

Field classification of white pine blister rust stem-cankers on resistant western white pine in northern Idaho and determination of respective tissue damage through tree ring analysis

Creator:: Eckert, Amy I.
Abstract:: Western white pine historically dominated northern Idaho’s forested landscape and was the Inland Empire’s most economically important tree. White pine blister rust, caused by the exotic fungus Cronartium ribicola, played a principal role in the decline of western white pine. The pathogen causes branch and bole cankers, which usually girdle...

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...

Validating songbird habitat relationship models

Creator:: Wilson, Dorothy G.
Abstract:: Models are commonly used to assess and predict wildlife response to management practices. Model validation is essential if managers are to use them with confidence. Fifteen forest bird-habitat relationship models were developed by biologists using data collected from private forestland in southwest Washington. These models predict species' probability of occurring...

Plant community dynamics in remnant and restored Willamette Valley wetland prairies

Creator:: Schwindt, Rachel A.
Abstract:: Invasion by exotic species can pose a major challenge for developing native plant communities in wetland restoration projects. Often native plant communities do not develop as anticipated in restored wetlands due to colonization by exotic species that dominate the native plant community. Despite the time and expense to restore wetlands,...

Community-based sea turtle monitoring and management at Helen Reef, Hatohobei State, Republic of Palau

Creator:: Barr, Julie M.
Abstract:: Remote areas are frequently homes to regional subpopulations of endangered green sea turtles (Chelonia mydas) and their essential habitat. Local communities are often the users and primary stewards of this valuable and charismatic resource. Recognizing this, a Hatohobeian community group in Palau has engaged in longterm monitoring and conservation management...

Functional groups, traits, and the performance of species in restoration

Creator:: Roberts, Rachael E. (Rachael Elaine)
Abstract:: In ecological restoration, species that are sown to increase the native plant diversity range in establishment ability. Some species readily establish, while others rarely do. This study set out to investigate some of the potential processes influencing species establishment, as well as the traits that are associated with the success...

The spatial distribution of beaver (Castor canadensis) impoundments and effects on plant community structure in the lower Alsea drainage of the Oregon Coast Range

Creator:: Perkins, Thaïs Erbel
Abstract:: Stream systems in the Pacific Northwest have come to be understood in the absence of beaver (Castor canadensis). To understand the effect of beaver upon riparian plant communities, four basins in the lower Alsea drainage were examined to determine the effect of beaver and their impoundments on streamside herbaceous/shrub and...
