The skeletal remains of an adult male individual from the 5JF52 site was analyzed to the extent allowed by the condition of the bony skeleton. The analysis includes a description of the material, dentition, demographic information pertinent to age, sex, stature and race, and a complete analysis of m

Years of drought and climate change are causing water resources to dwindle in the Colorado River Basin. But farmers and scientists are collaborating to learn how to grow crops with less water.

A right theropod pedal ungual phalanx II-3 from the Campanian Williams Fork Formation of northwestern Colorado is described, and a combination of features, including the large size, tapering distal tip, robust and stout overall form, triangular cross-section, and a relatively flat ventral surface al

Violarite from the Copper King mine, Boulder County, Colo., occurs as a secondary mineral after pentlandite. It is associated with fresh pyrrhotite and with several altered forms of pyrrhotite including secondary pyrite after pyrrhotite. Hence violarite has a much broader stability range in the oxid

The effect of altitude on the distribution of insects has not been widely studied, and except for isolated observations, no work has been done on the vertical distribution of the ground beetles (Carabidae). It is the purpose of this thesis to show the distribution of the Carabidae throughout the alt

We found that rare species, whether at low abundance or with a small range, do not disproportionately contribute to phylogenetic diversity in our subalpine plant community. These results were consistent across elevations. Instead, rare species might provide phylogenetic redundancy with common specie

rests directly, but unconformably, upon the Bridger or the Uinta, and all earlier formations in the region northeast and east of the Uinta and Blue Mountains of Utah and Colorado. The formation consists of finer and coarser

Abstract The Wilson Creek field is situated in mountainous terrain of Rio Blanco County, Colo. It was discovered in early 1938 and produces from both the Morrison and Sundance sands of Jurassic age. The underlying Sundance reservoir is fully developed with 18 wells; no dry holes have been drilled. T

In the next decade, climate models suggest that global temperatures will continue to rise. In the western United States, increases in temperatures and changes in precipitation patterns will escalate the risk of drought conditions. These potentially warmer, drier conditions could induce physiological

A survey of granitic rock surfaces, talus and outcrops, at 25 sites in Rocky Mountain National Park yielded 81 saxicolous lichen species. Fifteen species in 11 genera, or 19% of the total species, were dominant. Observed only once were 31% or 25 species. No new species were reported. Our results sho

Climate change is simultaneously increasing atmospheric carbon dioxide concentrations ([CO2]) and temperatures. We conducted a multi-factorial growth chamber experiment to examine how these climate change factors interact to influence the expression of ecologically relevant morphological and phenolo

During 1981-82, a roadside/plot survey was conducted on National Forest lands in Colorado to estimate annual merchantable cubic-foot volume loss caused by ponderosa pine dwarf mistletoe in ponderosa pine.This survey indicated that 18 percent of the type was infested.The total annual loss of ponderos

Abstract. Hillslope similarity is an active topic in hydrology because of its importance in improving our understanding of hydrologic processes and enabling comparisons and paired studies. In this study, we propose a holistic bottom-up hillslope clustering based on a region's integrative hydrodynami

Dispersal is common in mammals and can have an important role in shaping demography, genetics, distribution, and social structure. Dispersal entails potential costs but also potential benefits, and the dispersal decision is thought to be conditional; the potential disperser assesses prospects for su
