The U.S. Geological Survey (USGS), in cooperation with the Bureau of Reclamation, completed a review of dissolved selenium data collected from the Selenium Management Program network during each water year (WY) in the lower Gunnison River Basin, in western Colorado. The data tables include dissolved

The phenology of vegetation, namely leaf-out and senescence, can influence the Earth’s climate over regional spatial scales and long time periods (e.g., over 30 years or more), in addition to microclimates over local spatial scales and shorter time periods (weeks to months). However, the effects of

This data package includes processed and undiluted measurements for metal and anion concentrations from pore water (groundwater) samples from the Slate River floodplain of Crested Butte, CO, a focus field site for the SLAC Floodplain Hydro-Biogeochemistry SFA. The data was generated as part of the w

This data package includes a time-series of field measurements from May to October 2020 in groundwater and surface water from the Slate River floodplain in Crested Butte, CO, a focus field site for the SLAC Floodplain Hydro-Biogeochemistry SFA. The data was generated as part of the work targeting th

Thesis (M.A.)--Georgetown University, 2009.; Includes bibliographical references. This thesis explores the rhetorical methods utilized in the environmental movement. I employ the same rhetorical devices in my own environmental essay geared toward advocating for a proposed railway in Colorado.

Much of global biodiversity is comprised of parasitic organisisms. It is well recognized that the selective pressures imposed by parasites shape host defenses and life-history strategies. Many studies suggest that human changes to the environment facilitate pathogen emergence by disrupting establish

Metals-rich soils can occur naturally or through human activity, such as mining. Plants growing in metal-rich soils often incorporate metals into their tissues; the concentration of these metals can vary among tissues within a plant, among plants of the same species, and among species. Accumulation

As natural discontinuities of stream networks, beaver ponds have the potential to influence the structure and function of stream ecosystems. After declining during the extensive fur trade in North America, beaver populations have recently grown in some areas, especially montane regions. While previo

In flowering plants, environment-mediated hybrid fitness plays a large role in hybrid zone dynamics. The relationship of physiological traits to hybrid fitness, however, has not been described for many plant systems. In this study, we investigated the effects of soil moisture on water-use efficiency

Across different landscapes, plant abundance and richness change. Bee distributions may vary spatially in accordance to these differences in floral diversity. I used a habitat-based approach to investigate this hypothesis across three distinct meadow types: dry meadow, wet meadow-Veratrum and wet me

I examined the effect of forest fragment area on bird species richness and abundance in high- elevation Engelmann spruce (Picea engelmanni) and sub-alpine fir (Abies lasiocarpa) patches in Gunnison County, Colorado. Point counts were used to survey birds in 26 forest patches, ranging from 0.06 to 8.

There is an incredible diversity of floral morphologies and colors within plant communities of the southwestern, Rocky Mountains. However, little research has been done to quantify exactly how diverse these communities are, and to assess which ecological and phylogenetic processes are structuring th
