  • Development and application of a resource selection model for pygmy rabbits

    Creator:
    Meisel, Jennifer K.
    Abstract:
    Pygmy rabbits (Brachylagus idahoensis) in Oregon and Washington are a sagebrush (Artemisia tridentata spp.) obligate species of concern because of declining populations and extirpation from much of their range. Efforts are underway to establish a captive bred population of the Columbia Basin pygmy rabbit in Washington state for reintroduction into...

  • Evaluating space use and pesticide exposure risk for burrowing owls in an agricultural environment

    Creator:
    Gervais, Jennifer A.
    Abstract:
    Large burrowing owl (Aihene cunicularia) populations exist in areas of intensive agriculture in California, and pesticide exposure has been identified as a potential threat to population persistence. I evaluated breeding season use of agricultural fields by adult male owls using radio telemetry, and examined egg contaminant residues to estimate population-level...

  • Using Spatial Capture-Recapture to Estimate Density of Roosevelt Elk in Western Oregon

    Creator:
    Nelson, Jennifer E.
    Abstract:
    Spatial capture-recapture (SCR) is employed for estimating abundance and density of species, particularly those that are cryptic or solitary, and evaluating how population density varies with habitat. However, it is uncertain whether estimates are biased when applied to species that aggregate, such as elk (Cervus canadensis). Wildlife managers in the...

  • Hormonal and osmoregulatory aspects of smoltification in coho salmon, Oncorhynchus kisutch

    Creator:
    Specker, Jennifer Lee
    Abstract:
    Coho salmon smolts (Oncorhynchus kisutch) were transported at low and high densities. (12 and 120 g/L) for short and long periods (4 and 12 h). Because smolts can be transplanted directly to seawater, half of the fish in each treatment were transported to tanks containing seawater and half to tanks...

  • Integrative risk analysis of vector-borne disease

    Creator:
    Orme Zavaleta, Jennifer
    Abstract:
    In this dissertation I explore the application of two novel modeling techniques for improving risk analysis of vector-borne disease and discuss their potential use in integrating environmental risk assessment that guides environmental and public health decisions. Techniques for analyzing risk have been considered inadequate due to a lack of understanding...

  • Greater sage-grouse movements and habitat use during winter in central Oregon

    Creator:
    Bruce, Jennifer R.
    Abstract:
    Greater sage-grouse (Centrocercus urophasianus), a sagebrush obligate species, has contracted in extent by nearly half its original distribution. This is primarily due to habitat loss and degradation over the past 150 years. During winter, sage-grouse depend completely on sagebrush habitat for food and cover, yet sage-grouse winter ecology has been...

  • Patterns in responses of an amphibian assemblage to wetland restoration

    Creator:
    Rowe, Jennifer C.
    Abstract:
    Wetland restoration success in attaining wildlife conservation goals can be confounded by the presence of multiple biological invaders. Wetland management activities typically target invasive plants, but bottom-up responses of higher trophic levels in novel communities are difficult to predict. We surveyed plant and amphibian assemblages at 26 sites enrolled in...

  • Husbandry stress of Zebrafish, Danio rerio

    Creator:
    Ramsay, Jennifer Mara
    Abstract:
    Zebrafish, Danio rerio, are widely used as vertebrate research organisms yet little is know about their responses to husbandry stressors. This dissertation examined the whole-body cortisol responses of zebrafish to husbandry stress. Additionally, the effects of stress on the susceptibility to mycobacteriosis and microsporidiosis (Pseudoloma neurophilia) were determined including effects...

  • Evaluation of Pacific Lamprey Entosphenus Tridentatus Anatomical Structures as Records of Age and Isotope Histories

    Creator:
    Pelekai, Keala N.
    Abstract:
    The anadromous Pacific Lamprey (Entosphenus tridentatus) is a biologically and culturally important species native to the North Pacific Ocean and its adjacent freshwater tributaries. Pacific Lamprey have experienced declines in abundance and distribution throughout their native range, highlighting a need for further research on the species to better inform conservation...

  • Factors associated with dusky Canada goose nesting and nest success on artificial nest islands of the western Copper River Delta

    Creator:
    Maggiulli, Nicole Marie
    Abstract:
    The population of dusky Canada geese (Branta canadensis occidentalis; hereafter, dusky geese) nesting on the western Copper River Delta (CRD) in south- central Alaska has been in decline since the late 1970s. In an effort to alleviate mammalian predation, increase nest success, and avoid a listing under the U.S. Endangered...
