A study of flora along the vertical gradient of Avery Mountain with special emphasis on the identification of ubiquitous species on the west-facing slope
Investigating the role of climate on juvenile Golden-mantled ground squirrel (Callospermophilus lateralis) growth and behavior
Changes to climate can have a variety of consequences on organisms across all taxa. Though we are seeing climate changes across the globe, these effects can often be greater in high-elevation regions. For mammals in these environments, climate change can alter phenology, survival, and reproduction.
Avian Diversity in Aspen and Conifer Forests :
In order to compare avian diversity (species richness and evenness) between aspen and conifer forest communities in Gothic, Colorado, point counts were conducted in three replicates of each habitat type. Additionally, tree density and light measurements were performed as a measure of structural comp
Some metabolic and nutritive aspects of community structure with particular reference to the role of invertebrates in food chains, food webs, and trophic structure in marine, fresh-water, and terrestr
Diptera behavioral response to targeted <i>Bombus</i> removal
The Combined Effects of Aphid-Ant Mutualism and Fertilizer on the Resource Allocation of Valerian edulis
Valerian edulis is a perennial dicot growing in montane and subalpline regions. It is a polygamo dioecious species and popular host plant for aphids. Because of such characteristics, it was chosen to study the effects of resource allocation dependency. This study examined the specific effects of aph
The effects of environmental variation on daily abundance patterns and diet breadth of bumble bee species
A proposed plan for the restoration/reclamation of the Gunnison City Airport wetlands
Larval Feeding Ability on a Drought-Stressed Invasive Plant
Native species are threatened by the introduction of non-native and invasive organisms.
Direct and Indirect Consequences of Climate Change on Net Ecosystem Exchange.
The effects of spatial isolation on male and female functions in <i>Ipomopsis aggregata</i>
Causes of predation intensity in an ant/aphid mutualist system
Age effects on yellow-bellied marmot <i> (Marmota flaviventris)</i> maximum running speed
Age effects on maximum running speed (MRS) in yellow-bellied marmots (Marmota flaviventris) were examined to see whether this performance trait varied with age. Individuals were trapped in Tomahawk livetraps, then released and encouraged to run to burrows by yelling and chasing over varying distance
THE EFFECTS OF CLIMATE CHANGE ON THE TIMING AND ABUNDANCE OF DIPTERA IN A SUBALPINE MEADOW
Diptera play a critical role in alpine and subalpine ecosytems, though they are little studied in terms of what guides their timing and abundance. In order to reveal what cues dipteran timing this study was conducted for 24 years, using a Malaise trap to capture the insects, dipteran distributions w
Succession in pond C of the Kettle Ponds, Gothic, Colorado
Limnephilus externus Case Grazing
The subalpine region of Colorado hosts a variety of aquatic habitats. The organisms that inhabit these ecosystems are presented with many ecological adversities and differing predator guilds. Limnephilus externus caddisfly larvae native to montane and subalpine ponds of the Elk Mountains of Colorado
Changes in the biofluorescence of Ambystoma mavortium nebulosum with age
Climate disruption on avian species and communities in the southern Rocky Mountains
Climate change is altering the phenology and distribution of organisms across taxonomic groups. Abiotic factors vary along elevational gradients, including those that are affected heavily by climate change, especially temperature. In high elevation environments, species distributions are often limit
Effects of Daily Temperature Changes on Broad-Tailed Hummingbird Foraging Patterns
Climate change threatens the close relationship between wildflowers and the hummingbirds that pollinate them, both through gradual warming that shifts and misaligns their phenologies, and also potentially through increasingly erratic day-to-day temperature changes, a phenomenon especially apparent a
