Abstract Atmospheric nitrogen (N) deposition is driving changes in plant assemblages worldwide, but animal responses are not well understood, especially in relation to current widespread rates of low-level N deposition. Big sagebrush (Artemisia tridentata) is a foundation species in steppe ecosystem

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

Abstract Despite the crucial role of bioaerosol particles (BAP) in our climate system, local ecosystems, and human health, our grasp on their atmospheric interactions is hampered by a lack of high‐resolution and long‐term data, which is essential for understanding their abundance and variability in

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

Yellow-bellied marmots, Marmota flaviventer , are facultatively social and may form multigenerational societies, which are characterized by individuals sharing and defending space, possessing the ability to distinguish group members from outsiders and potentially persisting for many generations. I r

Levels of hybridization between related species can vary in response to evolutionary history or local environmental conditions, such as pollinators and abiotic factors, that affect reproductive isolation. Contact sites between the herbs Ipomopsis aggregata and Ipomopsis tenuituba vary in habitat typ

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

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

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

Scent marking and piloerection behavior in social groups of the common marmoset Callithrixj.

Adaptation of E. minimus to the semiarid habitat has involved changes in response to acute and chronic heat and water stress which increase the time the chipmunks can survive exposures to high ambient temperature, regardless of water availability.

Life histories of three species of Corixidae found only at altitudes over 2800 m were compared. The number of generations per year varied with altitude. Callicorixa audeni Hung. and Cenocorixa bifida Hung. had two or more generations a summer in montane ponds (below 3100 m) and only one generation a
