Early Snowmelt’s Effects on Floral Traits and Rewards of Two Subalpine Plant Species
The date of spring snowmelt is advancing in numerous alpine and subalpine ecosystems due to both rising temperatures and reduced snowpack associated with climate change. Snowmelt is a critical source of water for plants in subalpine ecosystems, so changes in snowmelt timing can affect many important

Exploring the impact of climate change on soil carbon storage in montane meadows
The excess of greenhouse gasses like carbon dioxide in the atmosphere urgently calls for a deeper understanding of existing natural mechanisms for carbon sequestration. Montane meadows act as a critical natural carbon sink, often having the capacity to store much more carbon in their soils than surr
Do pollinator and plant diversity vary with microclimate heterogeneity?
Montane landscapes are topographically complex and contain a biodiverse community of flora and pollinators. As with many other ecosystems, these subalpine and alpine landscapes are changing with the climate, altering the way these ecosystems regulate. As climates become warmer and drier, microclimat

Butterfly foraging and the dispersal of microbes among & within flowers
Dispersal is integral to the ecology and evolution of communities. Dispersal affects bacterial communities by impacting bacterial composition and diversity in many environments. One such environment is floral organs. Flowers are nutrient-rich environments for diverse and abundant microbes. Floral mi

Low to Mid Elevational Resurvey of Bumble bee Distributions in Response to Climate Change
In 1974, Graham Pyke conducted a study that examined Bombus spp. distributions along five transects around the Rocky Mountain Biological Laboratory area in Crested Butte, CO. The study was repeated in 2007 and within the intervening 33-year period, it showed that certain species of bumble bees had s

Dispersal of the golden-mantled ground squirrel
Dispersal, the permanent movement of an animal away from its location of birth, is common in mammals and can have an important role in shaping demography, genetics, distribution, and social structure. Dispersal entails potential costs but also potential benefits, and the dispersal decision is though
