Effects of soil temperature on fungal diversity and composition
(4/27/2018)Cryptic species, such as soil fungi, represent a highly diverse and undiscovered group. These organisms are responsible for important ecological processes and ecosystem services that regulate the environment and provide ... -
ENVIRONMENTAL AND BIOLOGICAL STRESSORS IN RELATION TO HONEY BEE COLONY COLLAPSE
(2018)Over the last several decades declines in pollinator populations, especially those of wild bees and other insects, have raised awareness of the economic impact pollination services have for crop production. This awareness ... -
FORECASTING CATTLE (BOS TAURUS) DEPREDATION RISK BY RECOLONIZING GRAY WOLVES (CANIS LUPUS) IN WASHINGTON
(2017)Preventing wolf-livestock conflicts requires identifying conditions placing livestock at risk and focusing outreach and adaptive management at a local scale. Risk mapping has become a popular tool to predict and display ... -
GEOLOGY, GEOCHRONOLOGY, AND GEOCHEMISTRY OF THE STIBNITE-YELLOW PINE GOLD-ANTIMONY-TUNGSTEN MINING AREA, IDAHO
(2019)The Stibnite-Yellow Pine mining area in central Idaho hosts gold, antimony, and tungsten in metasedimentary strata and Idaho batholith rocks. Garnet Lu-Hf geochronology and geothermobarometry yields an Early Cretaceous ... -
Habitat mapping and multi-scale resource selection of pygmy rabbits with unmanned aerial systems
(2019)Assessing habitat quality is a primary goal of ecologists. However, evaluating habitat features that relate strongly to functional habitat quality at fine-scale resolutions across broad-scale extents is challenging. Unmanned ... -
HYDROLOGIC CONTROLS ON NITROGEN CYCLING AND NITRATE TRANSPORT THROUGH THE VADOSE ZONE OF A SUBSURFACE ARTIFICIALLY-DRAINED DRYLAND AGROECOSYSTEM IN THE PALOUSE BASIN OF EASTERN WASHINGTON
(2015)Advances in the application of stable isotopes to address environmental issues have led to new understandings of biogeochemical cycles for both natural and agricultural systems. Of particular concern, is understanding ... -
HYDROLOGIC DYNAMICS CONTROL DISSOLVED ORGANIC MATTER EXPORT FROM WATERSHEDS: FIELD-SCALE PROCESSES IN A SMALL, ARTIFICIALLY DRAINED AGRICULTURAL CATCHMENT, AND PATTERNS ACROSS ECOSYSTEMS
(2014)Dissolved organic matter (DOM) is an important component of nutrient cycling and energy transfer within and between ecosystems. Understanding controls over the magnitude and quality of DOM that is transferred from soils ... -
Influences of the environment and plankton community interactions on toxic cyanobacterial blooms in Vancouver Lake, Washington, a temperate shallow freshwater system
(2015)Occurrences of cyanobacterial blooms are in freshwater systems are increasing in frequency and intensity largely in response to urbanization of landscapes, eutrophication, and climate change. Cyanobacterial blooms negatively ... -
INTERACTIONS BETWEEN NONNATIVE AMERICAN SHAD (ALOSA SAPIDISSIMA) AND FALL CHINOOK SALMON (ONCORHYNCHUS TSHAWYTSCHA) IN LOWER COLUMBIA RIVER FOOD WEBS
(2017)Lower Columbia River Food Webs have undergone many changes resulting from impoundment, introduction of nonnatives, and supplementation with hatchery salmon (Oncorhynchus spp.). American Shad (Alosa sapidissima) are an ... -
Low-δ RHYOLITES OF SOUTHWESTERN IDAHO AND VICINITY
(2010)This dissertation is divided into three chapters, each to be submitted to peer-reviewed journals, addressing the volcanology, petrology, and petrogenesis of rhyolitic volcanics in southwestern Idaho. Chapter 1: Conflicting ... -
MANAGEMENT IMPLICATIONS FOR A LACUSTRINE BROOK TROUT POPULATION: AN INVESTIGATION IN AGE PRECISION AND POPULATION DYNAMICS
(2019)Areas in the Columbia River Basin have been impacted by hydroelectric dam developments, requiring some anadromous and resident fish losses to be mitigated with resident fisheries enhancement. Brook Trout are one resident ... -
Mapping soil-landscape elements and the wetland in dambos and estimating CH4 and CO2 emissions from a dambo-terminated catena
(2014)Dambos are seasonally saturated grassy valleys mainly found on the central African plateau. They are usually sub-divided into three catenary units - gleyed and frequently inundated bottoms, flat and rarely inundated floors, ... -
Mapping, geologic evolution and petrogenesis of the McDermitt caldera center, northern Nevada & southern Oregon, USA
(2014)The McDermitt caldera center ("McDermitt") is a polygenetic mid-Miocene volcanic center along the border of northern Nevada and southern Oregon, USA, and is one of the first silicic centers associated with the Yellowstone ...
