Nest Distribution of <i> Bombus </i> spp. Across Different Habitat Types
Despite bumble bees’ critical importance as pollinators throughout the montane regions of Colorado, little research has been done on their nesting habits. In order to conserve the populations of Bombus spp. in the West, better knowledge of their nest density and nesting habitats is needed. I hypothe
Influence of plant abundance on pollination and selection on floral traits of <i>Ipomopsis aggregata</i>
Effects of Temperature on Voltinism in Subalpine Potter Wasps (Vespidae: Eumeninae)
Voltinism, the number of generations produced per year, is under both genetic and environmental control in insects. The rapid temperature increases associated with climate change could distort the information insects are obtaining from environmental cues and possibly alter the number of generations

The ecology and evolution of pathogens in a changing world
Infectious diseases are an integral part of natural ecosystems but also pose a serious threat to human health and agriculture. Understanding the multitude of factors shaping the epidemiology and evolution of pathogens is crucial for predicting and mitigating their effects, especially in a rapidly ch
Endangered mutualisms: the conservaiton of plant-pollinator interactions
Bumble bee queen plasticity and social regulation of traits
Studies on the physiological states of wild-caught organisms are essential to uncovering the links between ecological and physiological processes. Bumble bee queens emerge from overwintering in the spring. At this time, queens develop their ovaries and search for a nest site in which to start a colo

Nectar Yeasts in the Tall Larkspur <i>Delphinium barbeyi</i> (Ranunculaceae) and Effects on Components of Pollinator Foraging Behavior
Microorganisms frequently colonize the nectar of angiosperm species. Though capable of altering a suite of traits important for pollinator attraction, few studies exist that test the degree to which they mediate pollinator foraging behavior. The objective of our study was to fill this gap by assessi
