Effects of environmental variables and grazing on planted willow (Salix boothii Dorn) cuttings

Creator:: Lowson, Katherine L.
Abstract:: The influence of streambank location and timing of herbivory on success of planted Booth's willow (Salix boothii Dorn) cuttings along a Rosgen C5-type stream in an eastern Oregon meadow was determined. Willow cuttings were planted on two morphological locations (i.e. point bar and floodplain) in May of 2002 and 2003....

Reconnecting aquatic habitats : validating historical habitat use by anadromous fishes using telemetry and stable isotope analysis above barriers

Creator:: Lewis, Sierra Koch
Abstract:: I conducted a study to identify potential spawning habitat for anadromous salmonids above a 60-year-old hydropower dam in the headwaters of the North Umpqua River in Oregon. Like many other historical salmonid-bearing rivers, little documentation exists for anadromous fish presence above potential natural obstacles upstream of Soda Springs Dam. My...

TonB-dependent outer-membrane proteins of Pseudomonas fluorescens : diverse and redundant roles in iron acquisition

Creator:: Hartney, Sierra L.
Abstract:: Pseudomonas is a diverse genus of Gram-negative bacteria that includes pathogens of plants, insects, and humans as well as environmental strains with no known pathogenicity. Pseudomonas fluorescens itself encompasses a heterologous group of bacteria that are prevalent in soil and on foliar and root surfaces of plants. Some strains of...

Spatial and temporal variability of carbon dynamics in a tropical forest of Colombia

Creator:: Sierra, Carlos Alberto
Abstract:: Despite the importance of tropical forest ecosystems in the global carbon cycle, there have been few studies of carbon dynamics in this biome. The magnitude of carbon stocks in the tropics and their changes over time are poorly known since ground-based observations are lacking. In this study, total carbon stocks...

Environmental variability and system heterogeneity in terrestrial biogeochemical models

Creator:: Sierra, Carlos Alberto
Abstract:: Ecosystems are highly heterogeneous systems subjected to important levels of environmental variability; however, it is common in terrestrial biogeochemical models to assume homogeneous properties of the elements of the system or constant environmental conditions. For some processes, heterogeneity in these models is treated very simplistically, but there is not much...

Identification and distribution of the mating-type locus and development of cleistothecia of Podosphaera macularis

Creator:: Wolfenbarger, Sierra N.
Abstract:: Podosphaera macularis, causal agent of hop powdery mildew, is known to produce cleistothecia (syn. chasmothecia) in eastern North America and Europe, but ascocarps are not reported from the Pacific Northwestern region of North America. Reasons for the apparent absence of cleistothecia in the Pacific Northwest are unknown. We established that...

Factors influencing nest success of greater sandhill cranes at Malheur National Wildlife Refuge, Oregon

Creator:: Ivey, Gary L.
Abstract:: I developed a priori hypotheses and used logistic regression to model Greater Sandhill Crane (Grus canadensis tabida) nest success in relation to weather, habitat and management variables for cranes breeding at Malheur National Wildlife Refuge (MNWR) in southeast Oregon. My primary interest was to investigate the effects of habitat conditions...

Fold growth due to kink-band migration in repeated earthquakes, Sierra de Villicum, San Juan, Argentina

Creator:: Krugh, William C.
Abstract:: Growth strata geometries and deformed geomorphic surfaces reflect the shorttimescale growth of Sierra de Villicum (San Juan Province, Argentina). Accumulated deformation in repeated earthquakes is recorded by the structural geometry of deformed geomorphic surfaces. Through geologic mapping and topographic surveying, six strath terraces were identified on the eastern flank of...

Effect of the calpain inhibitor E-64-d on the degradation of α-fodrin in damaged muscle

Creator:: Boyd, Jeffrey
Abstract:: We hypothesized that calpain activity is elevated in response to muscle damage. To test this hypothesis, we examined the degradation of α-fodrin into its 150 and 145 kDa fragments following either 20 eccentric or isometric contractions. In addition, experiments were performed in the presence or absence of E-64-d, a calpain...

Assessment and Recommendations for Interpretive Programming around Climate Change at the Glades Wildlife Refuge

Creator:: Boyd, Kelsey
Abstract:: This paper identifies 51 best practices of interpretive programming in relation to the topic of climate change and applies those practices to interpretive programs delivered by Natural Lands, a Pennsylvania environmental non-profit organization, and specifically at the Glades Wildlife Refuge, one of Natural Lands’ nature preserves. The best practices are...
