Realtime micro-scale weather simulations were performed to support UAV (Uncrewed Aerial Vehicle) flights during the ISARRA Lower Atmospheric Process Studies at Elevation a Remotely-piloted Aircraft Team Experiment (LAPSE-RATE) field deployment. These simulations were performed by driving a nested gr

A trophic cascade is an ecological process in which predators affect the producer biomass and community composition of an ecosystem by limiting plant consumption by herbivores. Predators not only control herbivore populations through predation, but their mere presence can affect herbivore behavior.

We measured Specific leaf area for 23 plants across six elevational sites spanning a total of 610 meters. Within each site, we sampled twenty individuals from each species that was present to determine intraspecific variance in SLA. Nine species showed a significant positive relationship with elevat

Conflict and cooperation can drive how unrelated individuals interact, while illustrating whether the interests of two individuals converge or diverge. The subsocial, biparental beetle Nicrophorus investigator provides an excellent model to study these two interactions because researchers can manipu

Multi-species interactions profoundly affect community composition and function of ecosystems. Foraging behavior and resource allocation are two key factors that determine how species interact. This study investigates the role of floral nectaries and plant sex in mediating ant-aphid interactions on

In order to determine the degree of ecological damage inflicted as a result of mining operations around the Gothic area, three tailings piles were identified in Gothic and Crested Butte and an observational study of plant species on and around them carried out. It was found that both total numbers o

Scientists at the Rocky Mountain Biological Laboratory (RMBL) have recorded more mule deer (Odocoileus hemionus) activity density within the Gothic town site relative to outside the town site. One hypothesis to account for increased deer activity in Gothic is that coyotes, who prey on deer fawns, av

As global climate change responses are increasingly observed, theories in macroecology are being tested in order to up-scale species richness data to estimate extinction rates under habitat loss or degradation due to land use and climate change. Insight into effects that anthropogenic warming can ha

Changes in species distributions across elevations can be responses to anthropogenic climate disruption. Movement of species to higher elevations can result in local extirpations and colonization that could escalate and critically endanger native species. Studying systems that have experienced histo

Animal personality typically refers to a behavioral manifestations stable across time and contexts (Sih et al. 2004, Réale et al. 2007). Personality has been shown to shape fitness and may therefore shape population dynamics though such traits as dominance, response to stress, and reproductive perfo
