This archived Paleoclimatology Study is available from the NOAA National Centers for Environmental Information (NCEI), under the World Data Service (WDS) for Paleoclimatology. The associated NCEI study type is Tree Ring. The data include parameters of tree ring with a geographic location of Colorado

Realtime micro-scale weather simulations were performed to support UAV (Uncrewed Aerial Vehicle) flights during the ISARRA Lower Atmospheric Process Studies at Elevation a Remotely-piloted Aircraft Team Experiment (LAPSE-RATE) field deployment. These simulations were performed by driving a nested gr

For the past decade, the high-quality, relatively low-cost health care delivered in Grand Junction, Colorado, has led that community to outperform most others in the United States. Medicare patients in Grand Junction have fewer hospitalizations, shorter hospitalizations, and lower mortality rates af

ABSTRACT A nearly complete skull of Eutretauranosuchus delfsi was uncovered at the upper Jurassic Dry Mesa Dinosaur Quarry in the Brushy Basin Member of the Morrison Formation in western Colorado. It permits an expanded description of the taxon. Like the holotype, from Canyon City, Colorado, the Dry

In August 2009, President Barack Obama traveled to Grand Junction, Colorado, touting that community's health care system as a model for the provision of low-cost, high-quality care. According to the Dartmouth Atlas of Health Care, average per capita Medicare spending in Grand Junction was $6,599 in

Scientists vigorously debate the degree to which rock varnish is formed through the actions of microorganisms. To investigate this enigma, we utilized a three‐pronged approach that combined (1) culture‐independent molecular methods to characterize bacterial communities associated with varnish that c

Primers for 10 microsatellite loci developed specifically to amplify low quantity and quality DNA for Gunnison Sage-grouse were found to have levels of variability ranging from two to seven alleles, although one locus revealed significant departures from Hardy–Weinberg equilibrium.

We use relative dating criteria to document post-depositional alteration of till and periglacial deposits, and to map these deposits as facies of four allostratigraphic units (alloformations) in the Wind River Range. The alloformations are composed of till as well as rock-glacier, protalus-rampart,

The natural world is inherently complex, and the application of theories that reduce complexity may reveal general biological patterns that are otherwise obscured. The theoretical framework of ecological stoichiometry provides a lens through which to broaden understanding of complex ecological dynam

Non-native species and habitat degradation are two major catalysts of environmental change and often occur simultaneously. In freshwater systems, degradation of adjacent terrestrial vegetation may facilitate invasion by altering resource availability. Here we examine impacts of an invasive herbivoro

Status badges, such as bird plumage colors, are important parts of animal communication; they mediate intra- as well as intersexual interactions. Reliability of avian plumage badges is thought to be maintained by selective pressures, including social punishment. Costs, benefits, and resultant fitnes
