By migrating, ungulates take advantage of cyclical fluctuations in resources, which allows them to persist at greater population numbers than they would in the absence of these seasonal movements. We sought to identify the drivers of spring elk (Cervus canadensis) migration and evaluate how well ind

This is the AmeriFlux version of the carbon flux data for the site US-UR4 Gunnison - UCRB. Site Description - This site is located in Gunnison, Colorado, within a floodplain at a notable elevation. The region experiences cold winters with significant snow cover and cool summers. The ecosystem is hom

Astragalus microcymbus, the skiff milkvetch, is a perennial forb endemic to Gunnison and Saguache counties in Colorado, United States. In 1995 Denver Botanic Gardens scientists began monitoring individual A. microcymbus plants to track longevity and reproductive rates, ultimately recording plant len

Plant-pollinator interactions are extremely familiar to many different ecosystems all over the world. Many floral species and pollinators have developed intricate and essential adaptations to benefit one another. Aspects of plant reproduction require pollinator visits and many pollinators rely on fl

Flowering plants are in an evolutionary battle for the attention of pollinators to increase their fitness. However, microbes are increasingly recognized as key players in mediating interactions between plants and pollinators. Most studies of floral microbes have focused on the role of obligate necta

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

1. Beavers are ecosystem engineers. They alter the structure of their habitats when they cut woody vegetative material to create dams that result in ponds. Ponding slows water flow, resulting in fine sediment deposition. A wetland is created as the sediment continues to deposit. 2. The formation of

Spatial-temporal variation in pollinator populations can have an impact in plant reproduction. This study assessed the effects of elevation on flower abundance, pollinator visitation, and types of pollinators visiting the Helianthella quinquenervis This flower species was chosen due to its vast abun

In subalpine ecosystems, climate change has contributed to an earlier snowmelt as a result of warmer temperatures in the winter and spring. This shift may act to limit water availability for plant communities by prolonging the period between initial snowmelt and late-season monsoon rains, placing th

Sex and size allow for many different types of individuals within one species. These individuals can have different needs, which can influence responses to interaction, as well as what interactions take place between species members. We modeled how the sex and size of individuals of Valeriana edulis

Burying Beetles face both intraspecific and interspecific competition throughout the whole process of rearing a brood. Nicrophorus (burying beetles) are a well-studied genus that provides bi-parental care on the carcass resource that they bury for rearing their brood. Because carcasses are often rar
