Interspecific pollen transfer as a mechanism of competition: effect of Castilleja linariaefolia pollen on seed set of Ipomopsis aggregata
Are leafhoppers to blame? A study of the damage in aspen clones in Gunnison County, CO
Observing pollinator trait variation in relation to niche breadth in seasons of high and low precipitation
Interactions between plants and pollinators are complex and a change to one can cause a significant impact on the other. Environmental perturbations like drought can alter plant- pollinator systems, changing the relative abundance of flower species, shifting species distribution, and decreasing flor
The impact of climate change on Rocky Mountain plant communities: Differences in floral trait along an elevational gradient of transplanted communities
Alpine climates are seemingly adverse environments for plants. These habitats directly impact plants via pollinator scarcity and abiotic factors like extreme temperatures and precipitation that influence resource allocation. As a result, elevational gradients are natural laboratories that can be use
Predator and prey species have opposing responses to recreational trail use
While many ecological studies have investigated the impacts of recreation and trails on wildlife, we lack an understanding of how wildlife respond to recreational trails that exhibit seasonally dynamic levels of human activity. We used camera traps to assess changes in the presence of mammals along
The Direct and Interactive Effects of Warming and Species Interaction on Plant Functional Traits
Global climate change is a threat that continues to affect nearly every ecosystem on the planet through warmer temperatures, changes in precipitation patterns, and many other manifestations of a warmer world. Warming directly and indirectly affects plants and ecosystem functioning. In the natural wo
Epibiosis of Colacium on Daphnia
Effects of weather and floral density on foraging activity of cavity nesting bees (<i> Osmia </i>spp.)
Thermoregulation is an important factor for bee flight which ultimately contributes to an individual’s ability to forage and produce offspring. Rising temperatures could benefit insects by increasing their efficiency in reproduction and provisioning. However, warming could negatively impact floral r
Impacts of the invasive species <i> Linaria vulgaris </i> on soil ecology and native plant biodiversity
Invasive species are a major threat to biodiversity. Invasive plant species can alter ecosystems by outcompeting natives, lowering biodiversity, and change soil ecology. Additionally, invasive species can be costly to manage. Linaria vulgaris, a non-native noxious weed from Europe and Asia, was used
Trap behavior of <i> Zonotrichia leucophrys oriantha </i> at different elevations in the West Elk Mountains, Colorado
High-alpine ecosystems are particularly vulnerable to climate change. Thus, many ecosystem patterns are shifting due to warming temperatures, extreme weather events, and seasonal changes. This becomes an issue for birds that breed and live in high-elevation environments, as they may not be able to c
Seasonal manganese transport in the hyporheic zone of a snowmelt-dominated river (East River, Colorado)
Manganese (Mn) plays a critical role in river water quality since Mn-oxides serve as
Pollinator mediated reproductive consequences of altered co-flowering under climate change depend on abiotic context

Behavioral ecology and conservation biology
Oviposition variation among <i>Pieris napi</i> due to increasing glucosinolate levels in cruciferous hostplants
Adaptation and diversification of bluebells <i>Mertensia</i> spp., Boranginaceae
Flowering phenology marks the transition from vegetative growth to reproduction and exposes plants to seasonally varying selective environments during flowering. Life-history trade- offs between time and size at reproduction suggest that early-flowering species should generally be smaller than late-
Floral reward strategies, visitor behavior, and plant reproductive outcomes
Many plants that bear hidden or recessed floral nectar experience nectar robbing, the removal of nectar by a floral visitor through holes pierced in the corolla. Although robbing can reduce plant reproductive success, many studies fail to find such effects. We outline three mechanistic hypotheses th
King of the hill? How biotic interactions affect biogeographical pattern and species responses to climate change
As climate has warmed, many species have moved up mountains as physiological limits to their distributions have ameliorated. These distribution shifts are creating novel communities, begging the question: What happens to species at the tops of mountains as potential antagonists encroach upwards? The
The persistent maladaptation of <i>Pieris macdunnoughii</i>: Constraints on adaptation to an evolutionary trap
Evolutionary traps arise when organisms use novel, low-quality or even lethal resources based on previously reliable cues. Persistence of such maladaptive interactions depends not only on how individuals locate important resources, such as host plants, but also the mechanisms underlying poor perform
