Abstract:: Vernal pools are ephemeral surface water wetlands with unique hydrology, ecology and species composition. Rare and endemic species rely on vernal pool habitat due to specialization traits the species possess because they are adapted to the extreme conditions. Many vernal pool basins have been topographically and hydrologically altered and are...

Abstract:: Harney County contains defining characteristics of regions containing arsenic within the groundwater such as its location in the western United States, unique closed basin geography, complex geology, and seasonal groundwater level fluctuations. Confirmation of arsenic concentrations above the Maximum Contaminant Level Drinking Water Standard of 10 μg/L has been observed...

Creator:: Talabere, Andrew G.
Abstract:: The distribution of Lahontan cutthroat trout Oncorhynchus clarki henshawi was assessed in a high-desert stream in southeastern Oregon where beaver Castor canadensis are abundant. Longitudinal patterns of beaver ponds, habitat, temperature, and Lahontan cutthroat trout age group distribution were identified throughout Willow Creek. Three distinct stream segments were classified based...

Abstract:: Livestock grazing has been indirectly related to sage-grouse (centrocercus urophasianus) declines in the western United States and southern Canada; however, there is a lack of scientific research that directly relates the two. Our objective was to investigate the influence of livestock herbivory on sage-grouse nesting habitat by determining the spatial...

Creator:: Matney, Casey A.
Abstract:: All streams in Oregon that are inhabited by salmon and trout have a statemandated water temperature standard. However, temperatures of many streams, especially during summer months, exceed the seven-day average maximum temperature parameter (200 C for redband trout inhabited streams) accepted by the Oregon Department of Environmental Quality. To date,...

Abstract:: I assessed potential barriers to dispersal using homing tendency and investigated the movements and settlement site selection of pygmy rabbits (Brachylagus idahoensis) after short distance translocations in southeastern Oregon from June – December 2008. I captured, radio marked, and translocated 59 pygmy rabbits 1-2 km across landscapes with (1) continuous...

Creator:: Milliard, Justin B.
Abstract:: New data are presented that provide evidence for the onset of extensional deformation in the Northwestern Basin and Range within 1 million years after the eruption of the Steens Basalt at 16.5 Ma. New geologic mapping (1:24,000), stratigraphic sections, and ⁴⁰Ar/³⁹Ar dating of the Crane Basin rocks provide a control...
