Evolution of a pheromone signaling system in the salamander genus Plethodon (Amphibia: Plethodontidae)

Creator:: Picard, Amy L.
Abstract:: Animal signaling systems frequently utilize multiple traits to produce and transmit a signal. These system elements may span multiple levels of organization. Functional integration of these traits may be expected to generate concordance in evolutionary pattern among system elements, such that evolutionary change in one system component is correlated with...

Riparian vegetation and larval Pacific Giant (Dicamptodon tenebrosus) and adult Western Redback (Plethodon vehiculum) salamanders in the Oregon Coast Range

Creator:: Graff, Paula (Paula Hayes)
Abstract:: Riparian areas in the Pacific Northwest provide important biotic and abiotic features, such as down wood, moist microsites, and abundant invertebrate prey that benefit aquatic and terrestrial amphibians. Reported high densities of amphibians from streams and riparian areas in the Pacific Northwest highlight their importance in riparian food webs. Amphibians...

White-breasted nuthatch density and nesting ecology in oak woodlands of the Willamette Valley, Oregon

Creator:: Viste-Sparkman, Karen
Abstract:: Habitat loss causes a reduction in available resources for wildlife, alters the configuration of remaining habitat, and may isolate wildlife populations. White-breasted nuthatches (Sitta carolinensis) are experiencing long-term population declines in the Willamette Valley of Oregon, where they are historically associated with oak woodlands. As secondary cavity-nesters, white-breasted nuthatches may...

Mental and biophysical terrains of biodiversity : conservation of oak woodland on family forest

Creator:: Fischer, Alexandra Paige
Abstract:: This research analyzes how family forest owners conceptualize biodiversity in one high-conservation value area of oak woodland in the Willamette Valley of Western Oregon. Oregon white oak (Quercus garyanna) woodland, one of the most biologically diverse ecotypes in the state of Oregon, is in decline. Much of the oak ecotype...

Vegetation and soil response to tree removal methods in invasive western juniper woodlands

Creator:: O'Connor, Casey A.
Abstract:: On piñon-juniper encroached sites that lack the understory fuels to carry a prescribed fire, treatment options are limited to mechanical methods. Cutting with chainsaws and leaving the trees on site has been the primary treatment method for such sites, however this method creates a potential fire hazard, particularly in the...

The influence of environmental attributes on temporal and structural dynamics of western juniper woodland development and associated fuel loading characteristics

Creator:: Johnson, Dustin D.
Abstract:: Since European American settlement of the Intermountain Region, dramatic changes in vegetation composition and structure have occurred in the sagebrush steppe ecosystem. Western juniper (Juniperus occidentalis spp. occidentalis Vasek), although indigenous to the Intermountain Region, has increased since the late 1800s. Considerable work has been done documenting juniper woodland expansion...

(Re)claiming forestry : a case study of women's empowerment

Creator:: Redmore, Lauren E.
Abstract:: Nonindustrial private forest (NIPF) owners control a significant portion of forestland nationwide. Even though women own or manage NIPF lands, we know very little about how women manage forestland and what barriers women face in forest management. In addition, while there are several forestry organizations available to NIPF owners, few...

Is wave energy comparatively sustainable in Oregon?

Creator:: Yin, Yao
Abstract:: This essay provides a snapshot of sustainability and acceptability of wave energy and eight other electricity-generating energy sources in Oregon. Since “sustainability” is an important point of view in decision-making, the paper is centered around the concept. Although there is no consensus on the definition of sustainability in the academic...

Nature in chains : the effects of Thomas Jefferson’s rectangular survey on a Pacific Northwest landscape

Creator:: Schweickert, Tina K.
Abstract:: Understanding the impact of humans on the environment has long been a topic of scholarly interest and debate. As environmental problems mount, accounts of historic ecological conditions and the factors of change become increasingly useful. This study considers competing schools of interpretation about human impacts on ecological landscapes and develops...
