These data were compiled to measure airborne horizontal mass flux of sediments moved by wind across soils, climates, vegetation types, and land uses on the Colorado Plateau. Objectives of our study were to quantify spatial and temporal patterns in wind erosion and further our understanding of how so

This dataset contains a series of maps of projected threats and current state of habitats for the threatened Gunnison sage-grouse (Centrocercus minimus). The maps are 30-m spatially explicit projections of current habitats (2016) and future landscape change (by 2070) for the full range of the specie

The historical role of fire in sagebrush ( Artemisia tridentata ) landscapes remains poorly understood yet is important to inform management and conservation of obligate species such as the threatened Gunnison Sage-grouse (GUSG; Centrocercus minimus ). We reconstructed fire histories from tree-ring

The anion data for the East River Watershed, Colorado, consists of fluoride, chloride, sulfate, nitrate, and phosphate concentrations collected at multiple, long-term monitoring sites that include stream, groundwater, and spring sampling locations. These locations represent important and/or unique e

We investigated the impacts of an unpaved road on the distribution, reproduction, and stress physiology of Mountain White-crowned Sparrows (Zonotrichia leucophrys oriantha) in a high-elevation subalpine ecosystem. We found and monitored 152 sparrow nests over 3 years and captured 123 sparrows over 2

Yellow-bellied marmots were studied to understand the effects of specific types of human disturbance on antipredator behavior, a behavior whose performance enhances survival, and found that when the presence of motorized vehicles and bicycles was high, marmot increased the proportion of time spent v

Maximum Information Entropy theory, or MaxEnt, has been shown in many cases to accurately predict relationships between macroecological variables in ecosystems in a state of equilibrium. However, little testing has been performed on MaxEnt in disturbed sites. This study evaluated the accuracy of pre

Imazapic has shown potential to control invasive weeds, such as cheatgrass (Bromus tectorum L.), during ecological restoration, but effects on non-target native plants are poorly known. In a replicated field experiment, as part of restoration for Gunnison sage-grouse (Centrocercus minimus) in Colora

Metals-rich soils can occur naturally or through human activity, such as mining. Plants growing in metal-rich soils often incorporate metals into their tissues; the concentration of these metals can vary among tissues within a plant, among plants of the same species, and among species. Accumulation

The species-area relationship (SAR) is a widely used concept in ecology, yet there is much controversy over its form. It has traditionally been assumed either to have a simple universal power-law form, S = cAz, or to be idiosyncratic, varying from habitat to habitat, taxa to taxa, and spatial scale

Exploding growth along the Colorado Front Range has expanded the wildland-urban interface-the area where homes and vegetation mix.This area, known as the WUI, is at high risk of wildfires.Wildfire risk is based on both natural conditions, such as invasive species and climate change, and human develo

Bromus tectorum L. (Cheatgrass, Downy brome) is an invasive grass that has recently proliferated within the Gunnison Basin, Colorado. This study examined variation in germination in response to temperature, storage duration, and habitat. Four populations within the Gunnison Basin were sampled. Seeds

As human population and concomitant development increase, human-caused disturbances play an ever larger role in the fitness of wildlife. An increasing number of studies have implicated anthropogenic disturbance in having harmful effects on birds and other wildlife. Most studies, however, concentrate

Restoration Ecology is the science of techniques in which environmental degradation can be reversed and the previously existing ecosystems can be reestablished. Revegetation is a common restoration technique and I chose to investigate whether it could be applied to disturbed areas in high-altitude m

It is suggested that body size and age of first reproduction are important in explaining variation in disturbance tolerance in birds, and that species that capture live prey and those that are highly social are relatively wary.

SummaryIncreasing urbanization and recreational activities around and within biodiversity hotspots require an understanding of how to reduce the impacts of human disturbance on more than a single species; however, we lack a general framework to study multiple species. One approach is to expand on kn
