Predictors and Strength of Microclimate Buffering in the Gunnison Valley
Microclimate is an incredibly important factor in understanding how organisms behave and interact with their environment. Microclimate is defined as climate on a very small spatial resolution, referring to areas that may have differing climates than their surrounding macroclimate. Depending on the c

Effects of nectar-robbing bumblebees on hummingbird-pollinator behavior and plant reproductive success in <i>Ipomopsis aggregata</i> (Polemoniaceae)
Modeling spatial distribution of snow water equivalent using transfer learning across mountainous basins
Abstract Accurately estimating snow water equivalent (SWE) is crucial for understanding the impacts of climate change, urbanization, and population growth on water resources. High operational costs of lidar observations limit the frequency and coverage of SWE estimates at high spatial resolutions, l
RMBL Research in the time of Covid-19: Magical Realism?
Field Research in the Time of the Pandemic
The Where of Mineral Names: Creedite, Colorado Fluorspar Company Mine, Wagon Wheel Gap, Mineral County, Colorado
CREEDITE, Ca3Al2(SO4)(OH)2F8·2H2O, is a calcium aluminium sulfate fluoro-hydroxide. It forms colorless to white to purple, monoclinic prismatic crystals, frequently in acicular radiating sprays of ...
Differences in gene expression and genetic variation underlying preference-performance mismatches: insights from a specialized native herbivore on an invasive toxic plant
The causes for preference-performance mismatches in a specialist native herbivore laying eggs on an invasive toxic plant are investigated, and genes related to successful detoxification and adaptive feeding were enriched in larvae feeding on native plants and toxic plants.
Quantifying groundwater response and uncertainty in beaver-influenced mountainous floodplains using machine learning-based model calibration
AbstractBeavers (Castor canadensis) alter river corridor hydrology by creating ponds and inundating floodplains, and thereby improving surface water storage. However, the impact of inundation on groundwater, particularly in mountainous alluvial floodplains with permeable gravel/cobble layers overlai
The effect of human pressure on the flight initiation of montane breeding birds throughout the summer breeding season
The summer is a peak tourism season in the Colorado Rocky Mountains, but is also the breeding season for many montane bird species, resulting in an increase in bird-human interactions and coexistence. I measured the effect that human activity has on the flight initiation behavior of two montane bird
Does sodium in floral nectar enhance pollination & plant reproduction?
Effects of pond permanence on avian behaviors
As global temperatures rise due to climate change, aquatic ecosystems, such as alpine ponds, become more at risk of drying earlier than normal. These changes in pond hydrology have the potential to alter not only the aquatic ecosystems, but also terrestrial and riparian ecosystems, through resource

Effect of blood parasites on incubation efficiency of <i>Z. l. oriantha</i> in the Colorado Rocky Mountains
Haemoparasites are common in passerines and have known mild to detrimental effects on populations. It is important to understand how these effects influence nest incubation in females, as it could reflect future reproductive success of that species as vectors and transmission increase with climate c

Up high, hot and dry: Individual reproductive output in subalpine bees declines with increasing drought severity
Wild bees play indispensable ecological roles in many ecosystems, yet declines in many species have been documented in recent years. These declines have been linked to numerous anthropogenic pressures, including climate change, which can influence bee populations directly (i.e., via physiological me
Effects of Light Availability on Aspen Understory Species
Trembling aspen (Populus tremuloides) is a keystone species found throughout North America. P. tremuloides is a successional species which aids the regeneration of ecosystems after disturbance. However, climate change is altering aspen forest dynamics. Aspen forest die- off in the American Southwest
