Dust mass and horizontal aeolian sediment flux data from a sampler network on the Colorado Plateau, USA

These data were compiled to assess time series data of aeolian sediment collections across varying climates, vegetation cover, and land uses on the Colorado Plateau. The objectives of our study were to interpret aeolian erosion and deposition processes and measure horizontal sediment flux over the s

Investigating the air temperatures of different taxa in an alpine plant community

1. Ecology, like most science, is a rapidly progressing field in which new technologies are constantly being implemented in order to gain a wider and more holistic perspective on plant dynamics. 2. Plants can modulate their temperature via the process of transpiration and shading, which can also lea

Impacts of brood parasites, floral abundance, and bee age on maternal investment in a solitary bee, <i> Osmia iridis </i>

Parents can adjust both the size and number of offspring they produce in order to maximize their own fitness payoff (Smith & Fretwell 1974). Optimal parental investment is dependent in part on likelihood of offspring survival, which is impacted by predation and parasitism. When risk of predation or

Investigating the comparison between bird diversity and apex aquatic predators in sub-alpine beaver ponds

Predation of native salamanders by non-native trout in Colorado is a wildlife concern. Understanding the dynamics of how the different species interact is important. Cascade effects in the environment are caused by declines of species in a community. Birds, fish, and amphibians are deeply connected,

Effects of climate change on the elevational distribution of bumble bees near Crested Butte, CO: comparing data across 47 years

As climate change continues to alter the abiotic environment, many organisms must adapt to survive. In montane systems where changes in elevation can present noticeable changes in temperature and moisture, many organisms may adapt to climate change by migrating to higher elevations. Bumble bees, whi

Investigating the relationship between <i> Bombus appositus </i> abundance and its overlap with key floral resources

Many species of bumble bees (Bombus spp.) are experiencing population declines. In subalpine ecosystems, climate change is altering floral phenology by causing an earlier blooming period, which creates a growing season with sparser resources. Since bumble bees and their floral resources depend on ph

Comparative study on pollinator visits to high elevation plant communities in Virginia Basin, Gothic, Colorado

Plant-pollinator networks are intricate systems that can give insight on a location’s biodiversity and response to environmental changes. By studying pollination networks at different elevations, researchers can evaluate how varying environmental conditions influence how plant and pollinator species

Variation of Pollen Mass Across Species, Habitat Types, and Time

Bumble bees are crucial pollinators in both agricultural and wild ecosystems, and as pollinators they rely almost exclusively on floral resources as a source of food. However, in many natural and agricultural areas there has been a decrease in floral diversity and abundance, which in turn has caused

Are vigilance and flight initiation distance correlated in yellow-bellied marmots?

Behavioral syndromes are widespread and can have important ecological consequences, since correlations between distinct behaviors shape how animals can respond to changing pressures and can limit behavioral plasticity. Various antipredator behaviors have been identified within behavioral syndromes i

Pollination Preferences of <i> Geranium richardsonii </i> Between Bee and Fly Species at High and Low Elevations

Geranium richardsonii was studied at three different elevations to determine if there was a change in the type of pollinator species that visited it. The purpose of this experiment was to test the hypothesis that flies are more abundant at higher elevations and replace bee species found at lower obs
