Does snowmelt timing affect bumble bee colony abundance?
Average temperatures are increasing globally and causing shifts in the timing of weather events such as spring snowmelt, which may have profound consequences on the phenology of many organisms. Working at the Rocky Mountain Biological Lab in central Colorado, we examined the relationship between spr
A Recent Rockslide near Durango, in La Plata County, Colorado
Contrary to the somewhat sensational accounts in the public press, the rockslide on Carbon Mountain does not exhibit any unusual features. The slide involves the lower 100-125 feet of the Fruitland formation, of Upper Cretaceous age, which consists largely of shale and lies immediately above the Pic

Impacts of earlier snowmelt on fruiting phenology and seed success of Rocky Mountain wildflowers
Phenology, or the timing of biological events, has been found to shift in response to changing climates and key environmental cues such as spring temperatures and snowmelt date. These phenological shifts have been observed to be particularly extreme in mid-to-high latitude alpine environments, like
Effects of elevation on salamander life strategies
The Arizona Tiger Salamander (Ambystoma mavortium nebulosa) is a keystone species in the Rocky Mountains. Depending on how well they grow as larvae, these salamanders can either metamorphose to have terrestrial traits at maturity or retain their juvenile aquatic traits as adults. We expect that pond

Biotic and abiotic drivers of pathogen prevalence in a rust fungus with multiple plant hosts
Pathogens can have strong negative effects on individual fitness that scale up to influence population dynamics. Because of this, understanding the ecological contexts that shape pathogen transmission and prevalence is critical for understanding community dynamics and ecosystem function. Puccinia mo
Understanding aquatic insect oviposition to increase aquatic insect recruitment rates
Aquatic insects play many critical ecological roles in their environments. Anthropogenic changes in these environments, particularly those already under stress, leave the insect community more prone to stochastic disturbances. Despite widespread efforts by conservationists, many projects fail to inc
Vegetation structure effect on bird foraging behavior across the summer season in montane wet-meadows
Mountain White-crowned Sparrows and Wilson’s Warblers rely on foraging microhabitats in montane wet meadows during the breeding season to find food for themselves and their offspring. The microhabitats are comprised of vegetation, which can be food itself, but it can also be a substrate for inverteb
Reproductive ecology and pollination biology of Geum triflorum (prairie smoke)
Understanding plant reproductive strategies is important for interpreting population dynamics and species resilience. We investigated the mating system, pollen limitation, and pollinator interactions of Geum triflorum (prairie smoke), a subalpine wildflower. Experiments took place at the Rokcky Moun
Comparing decomposition rates and detritivore preferences for caddisfly (Trichoptera) cases versus ambient detritus
Humans manage microbes in their built environments by lowering humidity, filtering outside air, and applying antimicrobials that together fosters the selective dominance of microorganisms that can tolerate these harsh conditions and selects for antimicrobial resistance. Other species, however, regul
Assessing anthropogenic effects on golden-mantled ground squirrel and least chipmunk flight initiation distances
Species who commonly occupy territories within human settlements are exposed to frequent human disturbance, which has been linked to significant shifts in wildlife behavior in past studies. As urbanization and rural development continue to increase, we can anticipate cohabitation between humans and
The effects of snowmelt date, soil moisture, and precipitation on nectar and floral morphology of Ipomopsis
Climate change is putting montane plant species at risk that rely on historical patterns of precipitation and snowmelt timing. Floral traits, such as nectar production and morphology can be impacted by water availability. Hybridization of plants has the potential to provide adaptation to climate cha
The causes and consequences of pollen defence
Animal pollination represents one of the key innovations of the flowering plants, and constitutes
Quantifying ethanol in bumble bee honey and Colorado rocky mountain wildflowers
Ethanol is a natural byproduct of yeast fermentation of plant sugars. In flowering plants, yeasts often form mutualistic relationships by inhabiting nectar, where they benefit from access to sugar and confer antimicrobial protection through the production of ethanol. Ethanol in nectar not only shape
