The Role of Emerging Pathogens in Amphibian Population Declines : Experimental Evidence

Creator:: Hambalek, Natalie M.
Abstract:: Rapid rates of biodiversity loss have supported the notion that Earth is experiencing a sixth major extinction event. The causes of worldwide biodiversity loss are multifaceted and context dependent. One of the most prominent groups experiencing population declines and extinctions are amphibians. Several pathogens and their associated diseases are especially...

The static and cyclic pullout behavior of plate anchors in fine saturated sand

Creator:: Petereit, Ralph A.
Abstract:: Anchors resistant to tensile loads are commonly used in civil engineering practice. Anchors in the marine environment are most frequently used for the mooring of vessels. Only recently, with the expansion of the offshore industry, has the need to develop more reliable anchor systems become necessary. Embedded plate anchors are...

Modeling the habitat occupancy and abundance of salmonid ectoparasite Salmincola californiensis in Willamette Valley reservoirs

Creator:: Antonelli, Kelsi
Abstract:: The freshwater copepod Salmincola californiensis is an ectoparasite of Pacific salmonids (Oncorhynchus spp.) Threatened and endangered salmonids that rear in the reservoirs have been reported to experience higher rates of infection by S. californiensis than would be experienced by their stream-reared counterparts. These high levels of infection can lead to...

Paxton : a cartography

Creator:: Hogg, Charlotte
Abstract:: This thesis is a collection of essays about Paxton, a small town in western Nebraska, and an exploration of the contradictions and complexities found there. It is also a reflection on the layers of history and connections that exist not only among families that have lived in these towns for...

Responses of juvenile coho salmon and larval lamprey to instream habitat restoration in a Pacific Northwest stream

Creator:: Gonzalez, Rosalinda
Abstract:: Large wood has been utilized in many restoration projects to improve in-stream habitat in the Pacific Northwest for salmon. However, the benefits of this practice remain the subject of ongoing debate and evaluation of these projects has scarcely been done for non-salmonid species such as lamprey. In this study we...

Isotopic and Geochemical Signatures of Mantle and Crustal Contributions in Rhyolites from Okataina and Taupo volcanoes, New Zealand

Creator:: Rocco, Nicole D.
Abstract:: Silicic caldera-forming eruptions are some of the largest and most destructive volcanic eruptions known, and present significant local and global hazards. The underlying processes within crustal magma plumbing systems that lead to the accumulation and eruption of large volumes of evolved magma remain enigmatic, yet there is broad consensus that...

Ecology of the Salix and Populus species of the Crooked River National Grassland

Creator:: Busse, Kathryn Grace
Abstract:: Riparian communities dominated by members of the Salicaceae (Salix lasiandra, S. lutea, S. lemmonii, Populus trichocarpa, P. tremuloides and S. exiqua) were studied at the Crooked River National Grassland in central Oregon. The objectives of this study were to examine the relationships between the Salix and Populus species and microsite...

Autecology, reproductive ecology, and demography of Astragalus australis var. olympicus (Fabaceae)

Creator:: Kaye, Thomas N.
Abstract:: The goal of this study was to gather information on the autecology, reproductive ecology, and population dynamics of Astragalus australis var. olympicus as a baseline for conservation strategies and to help explain its restricted range. Approximately four thousand individuals occurred in four known population centers in the Olympic Mountains, Olympic...

An Assessment of Black-backed Woodpecker (Picoides arcticus) Vital Rates in Green and Burned Forests within a Pyrodiverse Landscape Mosaic

Creator:: Kerstens, Mark E.
Abstract:: Vital rates and population connectivity are fundamental concepts in animal ecology and such information is critical for successful conservation planning. The Black-backed Woodpecker (Picoides arcticus) is a species of conservation concern because of its strong association with forests recently burned by high-severity wildfire. However, several recent studies have found that...
