We examined how abiotic (warming), and biotic (presence of dominant plant species) factors interact to affect soil microbial processes in montane meadow ecosystems at high and low elevations at the WaRM experimental sites near the Rocky Mountain Biological Laboratory in Colorado in the West Elk rang

It is published quarterly by the Big Bee Project (Seltmann et al. 2021) to summarize all available knowledge about bee interactions from natural hist

The dataset accompanying the manuscript titled "Recent Upper Colorado River Streamflow Declines Driven by Loss of Spring Precipitation" provides comprehensive information on streamflow patterns in the Colorado River since 2000. The dataset is needed to run the analysis available on GitHub available

Insectivorous birds have ecologically important effects on prey abundance, behavior, and evolution, and through top-down control birds indirectly reduce herbivory and promote plant growth. While several studies sought to characterize biogeographic patterns in top-down control by birds, variation in

As global climate changes ephemeral freshwater systems face changes in historical hydroperiod with a shift towards shorter wet periods. Vernal ponds are one such type of lentic ephemeral system; in general they are relatively small and shallow, which causes them to dry in late spring or early summer

Competition for carcass resources can be fierce with a broad range of taxa vying for control of the nutrient rich resource. Arthropod competition for carcasses is well studied. Flies, beetles, and ants are common carcass utilizers. The burying beetle (Nicrophorus spp). is an obligate carrion breeder

Spatial patterns of the magnitude and rate of exhumation occurring during the late

This study utilizes apatite (U-Th)/He, or AHe, to produce a vertical transect of cooling histories along the height of the partially exhumed Crystal Pluton in the Elk Mountains of west/central Colorado. These cooling histories are interpreted to reflect exhumation controlled by the incision of the C

AbstractNoisy, unpredictable sounds are often present in the vocalizations of fearful and stressed animals across many taxa. A variety of structural characteristics, called nonlinear acoustic phenomena, that include subharmonics, rapid frequency modulations, and deterministic chaos are responsible f

During the downward trend of Quaternary global temperatures, crown-group marmots evolved to occupy harsh, seasonal environments at high latitudes and elevations. Marmots evolved hibernation and large body size, which allowed them to cope with a long, cold season with low, stressful ambient temperatu

Identifying forces that affect population dynamics can allow us to better understand the

Nest-site selection is important in the determination of nest success in several bird species (Holway 1991, Wells and Fuhlendorf 2005). Birds that nest in high elevation breeding sites are under greater environmental stress, making it even more crucial for individuals to choose nest microclimates th

Gunnison Sage-Grouse (Centrocercus minimus) is a species of concern for which little demographic information exists. To help fill this information gap, we investigated factors affecting nest success in two populations of Gunnison Sage-Grouse. We assessed the relative effects of (1) vegetation charac

Evocative sounds are known to elicit heightened responses from receivers across animal taxa. Many species of caregivers specifically have been shown to have increased arousal from infant baboon screams providing a unique conspecific identification for baboon mothers to discriminate their young from

Comarc Design Systems, at the request of AMAX Inc., has prepared the computer drawings of subsidence expected on Mount Emmons as a result of the mining of the Mount Emmons molybdenum deposit. The drawings show what can be expected after the deposit is depleted thirty or more years after mining begin
