A satellite-derived climatology of global ocean winds

Creator:: Risien, Craig Miller
Abstract:: A satellite-derived Climatology of Global Ocean Winds (COGOW) on a 0.5° latitude by 0.5° latitude grid is presented based on 5-years (August 1999 July 2004) of measurements from the SeaWinds scatterometer that was launched on 19 June 1999 onboard the QuikSCAT satellite. SeaWinds is an active microwave radar that estimates...

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...

A food web analysis of a Mojave Desert geothermal spring system and feeding ecology of Moapa dace (Moapa coriacea)

Creator:: StSaviour, Adam
Abstract:: Understanding food webs is fundamental in conserving endangered species and maintaining healthy ecosystem function, particularly in desert spring systems. We identified dominant energy sources in the Muddy River Warm Springs area, Clark County, NV using carbon and nitrogen natural abundance stable isotope analyses. We examined isotopic signatures of specific macroinvertebrate...

Linkages among land use, riparian zones, and uptake and transformation of nitrate in stream ecosystems

Creator:: Sobota, Daniel J.
Abstract:: Land use alters the physical and biological structure of stream ecosystems and potentially alters their capacity to process nitrogen (N), an essential nutrient that has nearly doubled in abundance on the biosphere during the past century from human activities. In this dissertation, I quantified uptake and transformation of nitrate (NO₃⁻)...

Diversity and community structure of aquatic insects in isolated montane desert streams

Creator:: Bogan, Michael T.
Abstract:: Local aquatic insect diversity and community structure is the result of multiple local and regional factors, and observed patterns depend upon the spatial and temporal scale under examination. Isolated stream systems in arid regions represent a new challenge in understanding the drivers of diversity and community structure, as most studies...

Characterizing Fine-Scale Neutral and Adaptive Genetic Diversity of Oncorhynchus mykiss in the Klamath Basin Before Dam Removal

Creator:: Piotrowski, Stanley J.
Abstract:: An inextricable link exists between dams and human development in the Pacific Northwest, but they can fragment rivers and reduce genetic connectivity for freshwater and anadromous fishes. Since the early-twentieth century, a series of hydropower and irrigation dams on the mainstem Klamath River, California, has fragmented migratory corridors and eliminated...

Semi-volatile organic compounds and developing organisms : accumulation in California mountain tadpoles in the field and fish embryo exposures in the laboratory

Creator:: Stanley, Kerri A.
Abstract:: The atmospheric transport and deposition of semi-volatile organic compounds (SOCs), including current and historic use pesticides, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), to mountain ecosystems may result in the exposure of tadpoles to these SOCs. This exposure has been implicated in amphibian population declines in California. Tadpoles encounter...

Modeling Fine-scale Avian Distributions and Densities with Multi-scale Models: Predicting the Past and Present

Creator:: Hallman, Tyler A.
Abstract:: Models of a species’ distribution and models of a species’ spatially explicit density are valuable tools for conservation. They allow researchers to estimate changes in distributions, densities, and populations, based on changing environmental conditions. To trust such estimates, however, the quality of models is exceedingly important. Model performance can be...

Feeding Ecology and Growth of Juvenile Chinook Salmon (Oncorhynchus tshawytscha) During Early Marine Residence

Creator:: Litz, Marisa Norma Chantal
Abstract:: The early marine phase following freshwater emigration has been identified as a critical period in salmonid (Oncorhynchus spp.) life history, characterized by high but variable mortality. Consistent with the “growth-mortality” and “bigger-is-better” hypotheses, at least some of the mortality during the critical period appears to be size-dependent – with smaller...

The effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies

Creator:: Miller, Scott W.
Abstract:: I used current water management practices in central and eastern Oregon and Washington as natural experiments to quantify the effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies. Reduced discharge had direct (e.g. decreased velocity and wetted habitat) and indirect (e.g. increased conductivity and temperature) effects...
