In the course of nesting microclimatic studies of the Broad-tailed Hummingbird (Selusphorus platycercus), I observed three cases of intra-or interspecific piracy of nesting materials. These observations were made in the vicinity of the Rocky Mountain Biological Laboratory, Gothic, Gunnison County, C

Abstract The carbonatite complex at Iron Hill is located southeast of the town of Powderhorn along Cebolla Creek, Deldorado Creek, and Beaver Creek in Gunnison County, Colorado. To reach the complex, travel 9 mi (14.5 km)west of Gunnison on U.S. 50 to the intersection with Colorado 149, turn south o

The overwhelming majority of research on wild bumble bees has focused on the social colony stage. Nest-­founding queens in the early season are difficult to study because incipient nests are challenging to find in the wild and the foundress queen flight period is very short relative to the entire ne

We report results from a 3-year field investigation to limit hybridization between native and nonnative suckers in 2 small tributaries of the Gunnison River basin, Delta County, Colorado. Upstream movement to spawning habitat was selectively impeded by picket weir in intermittent Cottonwood Creek. T

The Uncompahgre Uplift within the Colorado Plateau contains several salt anticline valleys. The Moab Valley is situated within one of these valleys which formed as the underlying salt member of the Paradox Formation migrated. As the unit migrated, the resulting collapse of the valley left behind sur

Recent work in central Utah has outlined the broader features of the area's thrust geometry. Although individual interpretations differ, most models indicate the region is similar to better understood segments of the Cordilleran thrust belt. Poor and limited seismic data and the paucity of drill-hol

Abstract Both theory and prior studies predict that climate warming should increase attack rates by herbivores and pathogens on plants. However, past work has often assumed that variation in abiotic conditions other than temperature (e.g. precipitation) do not alter warming responses of plant damage

Climate change and shifting environmental conditions can allow pathogens to spread into previously unburdened areas. For plant pathogens, this dynamic has the potential to disrupt natural ecosystem equilibria and human agriculture, making predicting plant pathogen range shifts increasingly important

To explore how field experiences can be designed to engage more community college students, the Undergraduate Field Experience Research Network (UFERN) held a "community conversation" (Community Colleges in the Field: Successful Programs and Strategies) on 15 October 2021. The hour-long virtual meet

This study examines a sample of artifacts recovered from the Vanoli Site (5OR30) encompassing a privy and trash midden located directly behind an historic Chinese laundry. Previous research in Overseas Chinese archaeology has focused on historically large Chinese communities and processes of accultu

Dispersal is an important individual decision which may influence individual fitness as well as population viability. The social cohesion hypothesis posits more social individuals remain at home, which is supported by prior work across taxa. However, how the sociality and connectivity of the group a

Hunter harvest is a potential factor contributing to population declines of sage-grouse (Centrocercus spp.). As a result, wildlife agencies throughout western North America have set increasingly more conservative harvest regulations over the past 25 years to reduce or eliminate hunter success and co

Snow provides fresh meltwater to over a billion people worldwide. Snow dominated watersheds drive western US water supply and are increasingly important as demand depletes reservoir and groundwater recharge capabilities. This motivates our inter- and intra-annual investigation of snow distribution p

The gut microbiome has a well-documented relationship with host fitness, physiology, and behavior. However, most of what is known comes from captive animals where diets and environments are more homogeneous or controlled. Studies in wild populations that experience dynamic environments and have natu

Abstract Maternal investment in mammals may take many forms, including spatial relocation of offspring. Litter relocation behavior, in which a female moves her litter to a new location, has been reported for several species of carnivores and rodents but has received little study. We describe litter
