The geochemistry and strontium isotope data for Coal Creek Watershed, Colorado, consists of cation, anion, and 87Sr/87Sr isotope values from samples collected at 8 stream location along Coal Creek, samples from two groundwater springs within the watershed, and a shallow subsurface piezometer. All st

Foliar elements were determined for samples collected in the field during a 2023 survey in Gunnison County, CO that also included paired data collection using an ASD FieldSpec3 spectrometer. Sampling locations were selected based on metal hotspots identified using remote sensing data and foliar elem

This dataset provides site and endmember spectra collected during the 2025 Colorado Headwaters Ecological Spectroscopy Study (CHESS) campaign. The site spectra were collected to help validate airborne hyperspectral data acquired by the National Ecological Observatory Network's aerial observation pla

Microorganisms play a key role in cycling nutrients and contaminants in the terrestrial environment depending on their genetic potential. Here, we present metagenome-assembled genomes (MAGs) for the bacterial and archaeal community in floodplain sediment samples taken June 2018 at two locations (OBJ

Microorganisms play a key role in cycling nutrients and contaminants in the terrestrial environment depending on their genetic potential.

This dataset includes groundwater and river water elevations and temperature data collected in the East River watershed located in the Upper Colorado River Basin. The data were collected in order to investigate the coupling between hydrology and biogeochemical processes in the floodplain. Data was c

Herbivorous insects are among the most successful radiations of life. However, we know little about the processes underpinning the evolution of herbivory. We examined the evolution of herbivory in the fly, Scaptomyza flava, whose larvae are leaf miners on species of Brassicaceae, including the widely

In order to determine the degree of ecological damage inflicted as a result of mining operations around the Gothic area, three tailings piles were identified in Gothic and Crested Butte and an observational study of plant species on and around them carried out. It was found that both total numbers o

Experimental infections of Arabidopsis thaliana (Arabidopsis) with genomically charac- terized plant pathogens such as Pseudomonas syringae have facilitated the dissection of canonical eukaryotic defence pathways and parasite virulence factors. Plants are also attacked by herbivorous insects, and th

Brassicaceae plants, such as bittercress (Cardamine cordifolia) produce characteristic glucosinolates, which are secondary metabolites used as defense compounds to deter pathogens and insect herbivores, such as the leaf mining fly (Scaptomyza nigrita). These compounds are produced constitutively and

I tested the oviposition preference of the leaf miner Scaptomyza nigrita of and within its native host plant Cardamine cordifolia. Gravid female S. nigrita were used in cafeteria-style choice tests to quantitatively evaluate feeding and oviposition preference between C. cordifolia from shaded and su

Visual-MINTEQ was used to compare observed and model-calculated percentage particulate Cu and Zn as influenced by sorption to both HFO and HMO and aqueous complexation with dissolved organic carbon, and differences between observed and modeled particulate varied significantly between sites and seaso

It has been decided in the committee that the logic topics to be studied under social impacts include, but are not limited to, housing, social services (police, mental and physical health) education, family and neighborhood relations, and quality of life. Although there will be some overlap with the

In a nutshell, Tri-State sold too much of its existing capacity to other utilities, leaving it short over the next few years. Now Tri-State may compound the mistake and raise rates further by building expensive units that solve neither a short-term nor a long-term problem. None of Tri-State’s severa
