Effects of human-made trails on local vegetative diversity
Genetic mechanisms underlying maladaptation in specialized species interactions
Adaptation has been used as the framework to understand the power of
Consequences of Nectar Robbing in Colorado Wildflowers: Insect Variation and Nectar Sugar Concentration
Nectar robbing is a process used by various insects to retrieve nectar from flowers that would otherwise be inaccessible. The community-level consequences of nectar robbing have not been widely studied, and the differences between primary and secondary robbing have been studied even less. Fitness co
Pond nutrient storage across permanence and temporal gradients
Our goal was to understand how range shifts in detrivorous larval caddisflies could affect nutrient storage along a pond permanence gradient in the Mexican Cut Preserve (Gunnison County, Colorado). As part of a larger project quantifying other ecological impacts and interactions arising from the cad
Mosquitoes: more likely nectar thieves than pollinators
Dormancy rates in microbial communities across an elevational gradient
Despite the broad impacts microbial dormancy has on ecosystems and ecosystem models, dormancy as a response to climate-change-related environmental stressors is poorly understood. Dormancy is an essential bet-hedging strategy used by microbes to tolerate unfavorable conditions and increase overall c
Contributions of Harry Gunnison Brown (1880–1975)
Sebbene le opere di Harry Gunnison Brown, prese singolarmente, non siano state trascurate in modo particolare, l’insieme della sua produzione scientifica non è ancora stato oggetto di attento esame. Dopo aver collaborate con Irving Fisher al suo volume sul potere d’acquisto della moneta, Brown pubbl

Climate Change Affects Boechera stricta Genotypes Through Local Maladaptation
As environments continue to change, plant communities will increasingly be pressured to adapt to their environment to maintain fitness levels. The most common release of climatic stressor result in range shifts and changes in phenology for plants. Boechera stricta, a perennial forb native to a range

Concentration-discharge behavior as an indication of groundwater contribution in Copper Creek sub-catchment of the Upper East River Basin
Groundwater in high elevation watersheds is difficult to quantify, but remains a major component in the hydrologic budget for the western United States. Concentration-discharge (C-Q) data can provide a framework for characterizing groundwater flow in small alpine catchments by indicating fluid resid
Does bumble bee (<i>Bombus spp.</i>) diet breadth vary with differences in floral resource abundance?
In the Rocky Mountains of Colorado, changes in the availability of floral resources through the growing season may affect the ability of bumble bee colonies to successfully complete their life cycle and produce reproductive individuals in the season’s end. A way bees could potentially deal with this
Analyzing the effect of climate change on <i>Boechera stricta</i> seed germination and fitness along an elevational gradient
Climate change alters many biotic and abiotic factors in environments around the world. At higher elevations in particular, climate change brings warmer mean temperatures, reduced snowpack, earlier snowmelt, and more extreme drought. In this study, we analyzed the effect of early snow removal on Boe
Bill Morphology and Niche Partitioning in <i>Selasphorus platycercus</i>
It has often been stated that the bill shape of hummingbirds is an example of ecological adaptation, as the morphology of their bills are strongly associated with flower nectar resources (Bleiweiss 1999). Broadtailed hummingbirds (Selasphorus platycercus) are considered the most characteristic h
Comparing clines in floral and vegetative traits along an elevation gradient in an <i>Ipomopsis</i> hybrid zone
Gene flow in hybrid zones acts as a barrier to speciation, yet we still see cases in which separate hybridizing species are maintained. Selection for different floral traits at each end of a hybrid zone by pollinators and for different vegetative traits by environmental gradients are two possible so
Behavioral strategies of golden-mantled ground squirrels, <i>Callospermophilus lateralis</i>
Observational studies of behavior provide insight into the fitness consequences of varying behavioral strategies in mammals. The behavior of golden-mantled ground squirrels (Callospermophilus lateralis, GMGS), an asocial hibernating species, is constrained by the energetic demands of reproduction, p
The Gothic Muse and Meta-Gothic Moment: Afterword to Russian Gothic Forum
Abstract The afterword offers an additional discussion related to the initial debate posed by the new developments in Russian Gothic as a special kind of literary genre. This article reviews, contextualizes and traces connections between the essays on Russian Gothic in this edition by Jeffrey Brooks
Mysteries of road dust: Does road dust influence flower lifespan in scarlet gilia?
This study aims to explore the exciting mysteries of road dust. In the beautiful Rocky Mountains, at the Rocky Mountain Biological Laboratory in western Colorado, there is an amazing diversity of plants, but one in particular near unpaved roads is Ipomopsis aggregata, Scarlet gilia, a perennial flow
Effects of experimental warming on herbivory and fungal pathogen load on subalpine grasses
Rising global temperatures are predicted to alter community dynamics by shifting species ranges and altering biotic interactions. Herbivory is expected to increase with prolonged growing seasons and heightened animal metabolic rates; pathogen damage may increase as well. Thus, we investigated whethe
The Role of Alpine Wetlands as Hot Spots of Dissolved Organic Carbon in the East River, Colorado
Dissolved organic carbon (DOC) is a critical chemical attribute of freshwater systems, affecting nutrient availability, toxicity and solubility of metals, and biological activity via the absorption of light and microbial consumption of O2 during DOC mineralization. Although DOC contributions to stre
