  • You are What, When, Where, and How you Eat : Mercury in Avian Food Webs across Multiple Spatial Scales

    Creator:
    Jackson, Allyson K.
    Abstract:
    Human alterations of landscapes take many forms, one of which is anthropogenic pollution. Mercury (Hg) is a complex contaminant because its uptake into the food web is not driven entirely by loading to the system; methylation is necessary to make Hg bioavailable and toxic to fish and wildlife. Because methylation...

  • Hawaiian duck (Anas wyvilliana) behavior and response to wetland habitat management at Hanalei National Wildlife Refuge on Kaua'i

    Creator:
    Malachowski, Christopher P.
    Abstract:
    The endangered Hawaiian Duck (koloa maoli; Anas wyvilliana), a non-migratory and island-endemic species, experienced a significant population decline during the twentieth century due to factors such as habitat loss, overharvest, introduced mammalian predators, and hybridization with introduced feral Mallards (A. platyrhynchos). A key objective for Hawaiian Duck recovery is to...

  • Trophic cascades and large mammals in the Yellowstone ecosystem

    Creator:
    Painter, Luke E.
    Abstract:
    Reintroduction of wolves to Yellowstone National Park (YNP) in 1995-96 provided a rare opportunity to observe the response of an ecosystem to the return of a top predator, including possible reversal of decades of decline of aspen, cottonwood, and tall willows suppressed by intensive herbivory on elk winter ranges. To...

  • The Effects of Road Noise on Pacific Chorus Frog Communication

    Creator:
    Nelson, Danielle V.
    Abstract:
    Amphibians are experiencing global population declines and are one of the most threatened groups of vertebrates. This can be attributed to multiple environmental stressors such as habitat loss, disease, invasive species, and climate change. For vocal amphibian species, loss of acoustic habitat due to anthropogenic noise may be yet another...

  • Reproductive success and foraging ecology of the rusty blackbird on the Copper River Delta, Alaska

    Creator:
    Loomis, David M.
    Abstract:
    The Rusty Blackbird (Euphagus carolinus) has suffered significant population declines across its entire geographic range and the mechanisms associated with this decline are poorly understood. Although much of the Rusty Blackbird breeding habitat in Alaska has remained relatively unaltered by anthropogenic activities, this species continues to decline by an estimated...

  • Beaver ecology in Bridge Creek, a tributary to the John Day River

    Creator:
    Maenhout, Julie L. (Harper)
    Abstract:
    The American beaver (Castor canadensis) was nearly extirpated by the late 1800's due to the fur trade. Due to reintroduction efforts, it now occupies much of its former range. Beavers are a keystone species and ecosystem engineers, greatly influencing riparian and instream habitats through selective harvesting of plant materials and...
