Conditional syndromes: Effect of human disturbance and age on the correlation between flight initiation distance and vigilance in marmots
Behavioral syndromes—suites of correlated behaviors across different situations and contexts—are widespread and can have important ecological consequences because correlations between distinct behaviors shape how animals respond to changing environmental conditions and can limit behavioral plasticit
Global Bee Interaction Data
Last modified: January 09, 2025 IntroductionThis dataset comprises all bee interactions indexed by Global Biotic Interactions (GloBI; Poelen et al. 2014). It is published quarterly by the Big Bee Project (Seltmann et al. 2021) to summarize all available knowledge about bee interactions from natural
Potential for Events Similar to the Deadly West Salt Creek Landslide, Grand Mesa Area, Colorado
ABSTRACT The deadly West Salt Creek Landslide of 2014, one of the largest landslides to occur in the United States in historical time, was surprising in its suddenness and length of runout. Its source area, the edge of Grand Mesa in western Colorado, was potentially the source of other similar lands
Dust mass and horizontal aeolian sediment flux data from a sampler network on the Colorado Plateau, USA
These data were compiled to assess time series data of aeolian sediment collections across varying climates, vegetation cover, and land uses on the Colorado Plateau. The objectives of our study were to interpret aeolian erosion and deposition processes and measure horizontal sediment flux over the s

Maps of habitat suitability improvement potential for the Gunnison Sage-grouse (Centrocercus minimus) satellite populations in Southwestern Colorado
Habitat restoration efforts to conserve wildlife species are often conducted along a range of local site conditions, with limited information available to gauge relative outcomes for habitat suitability among sites and identify those that may lead to the greatest returns on restoration investment. W
Analysis of the Potential for Events Similar to the Deadly West Salt Creek Landslide, Grand Mesa Area, Colorado
Habituation or sensitization? Long-term responses of yellow-bellied marmots to human disturbance
Abstract Continuous exposure to humans causes wildlife to either habituate or sensitize. Although increased tolerance may play an important role in coexistence with humans, the mechanisms and fitness outcomes of long-term changes of tolerance are not fully understood because only a few studies have
High-discharge disturbance does not alter the seasonal trajectory of nutrient uptake in a montane stream
A Case Study of Novel Landslide Activity Recognition Using ALOS-1 InSAR within the Ragged Mountain Western Hillslope in Gunnison County, Colorado, USA
The “East Muddy Creek Landslide Complex” in Gunnison County, Colorado, USA destroyed Colorado State Highway 133 from 1986 to 1987 and has been investigated over decades during different periods of reactivation. This paper presents a case study of novel landslide activity recognition related to the l
Are Lek Disturbance Buffers Equitable for All Gunnison Sage-Grouse Populations?
Abstract Lek disturbance buffers can be used to identify areas that provide important seasonal habitat for Gunnison sage grouse Centrocercus minimus (hereafter GUSG), a species with declining or vulnerable populations across their range. Lek disturbance buffers define areas around leks where anthrop
Comparing the level of human disturbance in 2009 and 2018 at yellow-bellied marmot (<i>Marmota flaviventer</i>) colonies
Natural areas and the animal communities within them are inevitably affected by human disturbance. Human disturbance can occur through tourism, ecotourism, and simply human presence. The effect of a human on an animal can be detrimental, and has even been shown to cause increases of stress response,
Pocket gopher (<i>Thomomys talpoides</i>) soil disturbance peaks at mid-elevation and is associated with air temperature, forb cover, and plant diversity
Burrowing mammals can be ecosystem engineers by increasing soil aeration and erosion and altering the structure of plant communities. Studies that characterize the constraints on the distributions of fossorial mammal disturbances to soil can help predict changes in ecosystem engineering under future
Altered Fire Regimes and the Persistence of Quaking Aspen in the Rocky Mountains: A Literature Review
The persistence of quaking aspen (Populus tremuloides Michx.) is of significant importance to land managers in the Rocky Mountain region. Fire suppression in the past century has been im- plicated as a mechanism influencing aspen population dynamics, as aspen are generally consi- dered an early sera
Disturbance legacies and nutrient limitation influence interactions between grazers and algae in high elevation streams
Debate about control of interaction strength among species is fueled by variation in environmental contexts affecting food webs. We used extensive surveys and two field experiments to test the individual and interactive influences of variation in the assemblages and associated traits of grazers as s
Cost shared wildfire risk mitigation in Log Hill Mesa, Colorado: survey evidence on participation and willingness to pay
Wildland–urban interface (WUI) homeowners who do not mitigate the wildfire risk on their properties impose a negative externality on society. To reduce the social costs of wildfire and incentivise homeowners to take action, cost sharing programs seek to reduce the barriers that impede wildfire risk
Plant Successional Changes Over 67 Years on the Gothic Earthflow.
Long term data on stages of plant succession on bare areas is extremely useful in determining patterns of revegetation over longer periods of time. Understanding of these patterns can have application in conservation and restoration. This study examined plant community composition data for a subalpi
Characterizing disturbance regimes of mountain streams
Characterizing biologically relevant stream disturbance regimes is challenging, but necessary to answer questions about disturbance effects on ecological processes. No universally accepted approach exists for characterizing stream disturbance regimes. Our goal was to evaluate approaches that can be
