Specialization and foraging ergonomics in a subalpine bumblebee <i>Bombus appositus</i> (Hymenoptera: Apidae)
The distribution of genetic variation in a social mammal, the yellow-bellied marmot
A Comparative Analysis of Saxicolous Lichen Diversity and Cover along an Elevation Gradient on Talus Slopes in Gunnison National Forest to Infer Possible Climate Change Effects
Climate change in Colorado has already increased temperatures by 2 ℉ and is predicted to continue to rise. Precipitation during winter months is predicted to increase, while projected precipitation for the spring, summer and fall is still uncertain. It is important to understand how saxicolous liche
Role of animal detritivores in the breakdown of emergent plant detrius in temporary ponds
Across Caste Variation of Proboscis Length and Within Caste Phenotype Matching of Subalpine Bumble Bees (<i>Bombus spp.</i>)
Bumble bees (Bombus spp.) are eusocial insects that typically consist of three castes, with each caste emerging and foraging at different times. Bumble bee queens and workers differ morphologically in several measurable traits, but morphological variation within species and within caste has not be
Effects of abiotic and biotic stress on plant fitness and herbivore defense in Boechera stricta
Abiotic and biotic factors influence plant fitness by altering the physical environment and resource availability. According to the stress gradient hypothesis, increasing physical stress in an environment increases positive plant-plant interactions and decreases negative interspecies interactions. I

Differential predation of mayfly larvae and damselfly larvae by tiger salamanders
Effect of the presence of aphids (Aphididae) on oviposition in the pre-dispersal seed predator <i>Hylemya</i> (<i>Delia</i>) spp. on the host plant <i>Polemonium foliossissimum</i> (Polemoniaceae)

Colony growth and reproduction in the ant species <i>Formica neorufibarbis</i>
The Relationship between Soil Properties and Variation in the Morphology and Phenology of non-native mustard plant <i>Thlaspi arvense</i> in Subalpine Meadows
The ability of soil to retain moisture can significantly impact the severity of droughts on plants. Deep, loamy soils retain moisture from snow melt into the dry season more efficiently than shallow, sandy soils that lose water to runoff and percolation. Soil depth and texture are thus significant i
Can Variation of Insect Populations Affect Mountain White-crowned Sparrow Daily Nest Survival?
Mountain white-crowned sparrows’ (Zonotrichia leucophrys oriantha; hereafter MWCS) diet fluctuates across seasons given their changing nutrient requirements across life stages and environment. Insect population densities may influence the daily nest survival of MWCS who depend upon these organisms a
Comparing Plant-Pollinator Network Structure between Drought and Non-Drought Years
Network analyses can be used to examine multi-species interactions and have been applied to many ecological interactions such as food webs, antagonistic relationships such as plant- herbivory, and mutualistic relationships. A particular focus has been on plant-pollinator interactions given their imp
