Paleoindian archaeology of the Upper Gunnison Basin, Colorado Rocky Mountains
The past two decades have seen a fluorescence of work at Paleoindian sites in Colorado’s Upper Gunnison Basin (UGB). This article presents and synthesizes the results of that work in two parts, the first, a landscape-scale analysis of 82 UGB Paleoindian components as reported in Colorado state site
Social control is associated with increased reproductive skew in a wild mammal
In group-living species, reproductive variation among individuals of the same sex is widespread. By identifying the mechanisms underlying this reproductive skew, we gain fundamental insights into the evolution and maintenance of sociality. A common mechanism, social control, is typically studied by
Concentration-Discharge Relationships of Dissolved Rhenium in Alpine Catchments Reveal Its Use as a Tracer of Oxidative Weathering
Abstract Oxidative weathering of sedimentary rocks plays an important role in the global carbon cycle. Rhenium (Re) has been proposed as a tracer of rock organic carbon (OC petro ) oxidation. However, the sources of Re and its mobilization by hydrological processes remain poorly constrained. Here, w
Evaluating 3 decades of precipitation in the Upper Colorado River basin from a high-resolution regional climate model
Abstract. Convection-permitting regional climate models (RCMs) have recently become tractable for applications at multi-decadal timescales. These types of models have tremendous utility for water resource studies, but better characterization of precipitation biases is needed, particularly for water-
NOTES ON THE INSECT FAUNA OF HIGH ALTITUDES IN CUSTER COUNTY, COLORADO
The faunæ of high altitudes always posses a peculiar interest by virtue of the light they throw on problems of geographical distribution, and especially the distribution in ancient times of what is now a strictly Arctic and Alpine fauna. For this reason, the following lists of species, fragmentary a

Multi-decadal and multi-centennial variability in Colorado River streamflow
A 1240-year-long record of reconstructed annual flows of the Colorado River at Lees Ferry is analysed using singular spectrum analysis and multi-taper method of spectral analysis. Spectral analysis of the 100-year-long recent record of annual flows of Colorado River in the measured and reconstructed

Effect of elevation, season and accelerated snowmelt on biogeochemical processes during isolated conifer needle litter decomposition
Increased drought and temperatures associated with climate change have implications for ecosystem stress with risk for enhanced carbon release in sensitive biomes. Litter decomposition is a key component of biogeochemical cycling in terrestrial ecosystems, but questions remain regarding the local re

Topographic Map Analysis of the North Platte River-South Platte River Drainage Divide Area, Western Larimer County, Colorado, USA Eric Clausen
The United States Supreme Court settled legal disputes concerning four different Larimer County (Colorado) locations where water is moved by gravity across the high elevation North Platte-South Platte River drainage divide, which begins as a triple drainage divide with the Colorado River at Thunder
Does pollination interact with the abiotic environment to affect plant reproduction?
Although we found some evidence for the effect of a biotic interaction depending on abiotic conditions, it was only for one aspect of reproduction in one species, and it was in an unexpected direction. Our work highlights interactions between the abiotic and biotic components of the environment as a
Timber Losses from West Fork Complex Fire in Southwest Colorado
Abstract This article provides an assessment of fire effects on timber burned in the West Fork Complex fire area, located in the San Juan Mountains of Colorado. The West Fork Complex fire burned 109,615 acres in 2013, and suppression costs alone totaled $33.2 million. Much of the fire occurred in sp

Molecular nature of mineral-organic associations within redox-active mountainous floodplain sediments
Floodplains are critical terrestrial–aquatic interfaces that act as hotspots of organic carbon (OC) cycling, regulating ecosystem carbon storage as well as export to riverine systems. Within floodplain sediments, regular flooding and textural gradients interact to create dynamic redox conditions. Wh

PASSIVE TREATMENT OF MINING INFLUENCED WASTEWATER WITH BIOCHEMICAL REACTOR TREATMENT AT THE STANDARD MINE SUPERFUND SITE, CRESTED BUTTE, COLORADO
A pilot biochemical reactor (BCR) with a design flowrate of 3.8 l/m (1 gpm) has been operating at the Standard Mine Superfund Site for over four years, since August, 2007. The pilot system is entirely passive, using solar energy to power sampling equipment and pumping requirements. BCR treatment rel
