Heartwood decay and vertical distribution of red-naped sapsucker nest cavities
Acute toxicity tests: range-finding and predictive tests of the effects of copper on immature rainbow trout
The effect of pocket gopher herbivory on the limitation of aspen outgrowth
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
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
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
Time allocation to behavior in marmots: a comparison of adults and juveniles
The Impact of Delphinium nuttallianum and Ipomopsis aggregata Phenology on Broad-tailed Hummingbird (Selasphorus platycercus) Visitation Patterns
Biological interactions reliant on synchronized phenology are being thrown into disarray with warming temperatures and an earlier onset of spring. Migrating Broad-tailed Hummingbirds (Selasphorus platycercus) in Gothic, Colorado tend to arrive and breed in alignment with wildflower flowering phenolo
The short life of upvalley wind in a high-altitude valley in the Colorado Rocky Mountains
Abstract Thermally driven upvalley (UV) wind in the upper East River Valley in the Colorado Rocky Mountains often unexpectedly stops in midmorning and reverses back to downvalley (DV) wind. We use a comprehensive observational data set for a nearly two‐year long period to analyze the wind system and
Genetic diversity, disease incidence, and pathogen-mediated selection in apomictic <i>Arabis</i> (Brassicaceae)
Comparing floral morphology and inflorescence structure of Lupins argenteus and L. bakeri in sympatry and allopatry
Differences or similarities in floral morphology can affect the interactions between plants and shared pollinator communities. As such, plant species with similar floral morphology may be competing for pollinators or facilitating pollinator attraction. Thus, pollinators mediate selection on floral m
Climatic variation and risk assessment in a highly seasonal mammal
Climate change and its resulting effects on seasonality are known to alter a variety of animal behaviors including those related to foraging, phe- nology, and migration. Although many studies focus on the impacts of phenological changes on physiology or fitness enhancing behaviors, fewer have invest
Spatial genetic structure of <i>Delphinium nuttallianum</i> populations: inferences about gene flow
Nowhere to go but Up: Investigating Bumble Bee population Shifts over Elevational Gradients
Bumble bees are important pollinators in both the wild and in agriculture; however, several species globally are under threat due to multiple anthropogenic factors. One of these threats is climate change, and many bumble bee species have adapted by moving up in elevation. This has only been observed
The Impact of Delphinium nuttallianum and Ipomopsis aggregata Phenology on Broad tailed Hummingbird (Selasphorus platycercus) Visitation Patterns
Biological interactions reliant on synchronized phenology are being thrown into disarray with warming temperatures and an earlier onset of spring. Migrating Broad-tailed Hummingbirds (Selasphorus platycercus) in Gothic, Colorado tend to arrive and breed in alignment with wildflower flowering phenolo
In your stomach or in your nectar? Disentangling the effects of two pollination-related yeasts on bumblebee behavior and foraging
The study of plant-insect interactions and pollination has just begun to scratch the surface of the microbes that inhabit many of the surfaces involved in these interactions. While most microbial studies have focused on the roles of obligate nectar yeasts in mediating pollinator behavior and fitness
