Cold-Air Pooling Maps for Colorado (100 m) and the East River Watershed Region (30 m)
Cold-air pooling (CAP) mapped across Colorado at 100m resolution and the region surrounding the East River watershed, CO at 30m resolution. Classifications were determined using a Python implementation of the algorithm originally developed in Lundquist et al., 2008, applied to digital elevation mode
Colorado Cold-Air Pooling Maps and SNOTEL Station Classifications
This dataset contains maps of cold-air pooling (CAP) across Colorado at 100m resolution (Colorado_100m.nc) and the region surrounding the East River watershed, CO at 30m resolution (EastRiver_30m.nc). Classifications were determined using a Python implementation of the algorithm originally developed
Plant and carbon data, snowmelt manipulation experiment, Rocky Mountain Biological Laboratory (RMBL), 2023
These data are from a 2023 snowmelt manipulation experiment in Vera Meadow at the Rocky Mountain Biological Laboratory. We experimentally advanced the snowmelt date in a montane meadow by approximately 12 days using black shade cloths and assessed the effect on plant and carbon dynamics. We measured

Intraspecific body size variation across distributional moments reveals trait filtering processes
Natural populations are composed of individuals that vary in their morphological traits, timing and interactions. The distribution of a trait can be described by several dimensions, or mathematical moments-mean, variance, skew and kurtosis. Shifts in the distribution of a trait across these moments
Firmicutes and Bacteroidetes contribute to mass gain variation in female obligate hibernators
Abstract Obtaining body condition is an important life history challenge that directly impacts individual fitness and is particularly important for hibernating animals, whose maintenance of adequate body fat and mass is essential for survival. It is well-documented that host-associated microorganism
Elevated [CO2] and temperature augment gas exchange and shift the fitness landscape in a montane forb
Climate change is simultaneously increasing carbon dioxide concentrations ([CO 2 ]) and temperature. These factors could interact to influence plant physiology and performance. Alternatively, increased [CO 2 ] may offset costs associated with elevated temperatures. Furthermore, the interaction betwe
Decomposing an elevational gradient in predation by insectivorous birds
Abstract Insectivorous birds have ecologically important effects on prey abundance, behavior, and evolution, and through top‐down control, birds indirectly reduce herbivory and promote plant growth. While several studies sought to characterize biogeographic patterns in top‐down control by birds, var
Polyphenism predicts actuarial senescence and lifespan in tiger salamanders
Actuarial senescence (called 'senescence' hereafter) often shows broad variation at the intraspecific level. Phenotypic plasticity likely plays a central role in among-individual heterogeneity in senescence rate (i.e. the rate of increase in mortality with age), although our knowledge on this subjec
Declining groundwater storage expected to amplify mountain streamflow reductions in a warmer world
Abstract Groundwater interactions with mountain streams are often simplified in model projections, potentially leading to inaccurate estimates of streamflow response to climate change. Here, using a high-resolution, integrated hydrological model extending 400 m into the subsurface, we find groundwat
Consequences of nuisance algal blooms of Didymosphenia geminata on invertebrate communities in Rocky Mountain streams
As climate change accelerates, low summer stream flows are becoming increasingly common in the Colorado Rocky Mountains, USA. The diatom Didymosphenia geminata (Lyngb.) M. Schmidt, typically observed under low-flow and low-P conditions, produces nuisance growth—persistent and extensive proliferation
The hole truth: why do bumble bees rob flowers more than once?
Primary nectar-robbers feed through holes they make in flowers, often bypassing the plant's reproductive organs in the process. In many robbed plants, multiple holes are made in a single flower. Why a flower should be robbed repeatedly is difficult to understand: a hole signals that a nectar forager
A tale of two catchments: causality analysis and isotope systematics reveal mountainous watershed traits that regulate the retention and release of nitrogen
Abstract Mountainous watersheds are characterized by variability in functional traits, including vegetation, topography, geology, and geomorphology, which determine nitrogen (N) retention, and release. Coal Creek and East River are two contrasting catchments within the Upper Colorado River Basin tha
Costly calling: Marmots who alarm call at higher rates are less likely to survive the summer and live shorter lives
Emitting alarm calls may be costly, but few studies have asked whether calling increases a caller's risk of predation and survival. Since observing animals calling and being killed is relatively rare, we capitalized on over 24,000 h of observations of marmot colonies and asked whether variation in t
Detecting context dependence in the expression of life history trade-offs
Life history trade-offs are one of the central tenets of evolutionary demography. Trade-offs, depicting negative covariances between individuals' life history traits, can arise from genetic constraints, or from a finite amount of resources that each individual has to allocate in a zero-sum game betw
Mountainous floodplain connectivity in response to hydrological transitions
Abstract In mountainous watersheds, floodplain sediments are typically characterized by gravel bed layers capped by an overlying soil unit that serves as a hotspot for biogeochemical reactivity. However, the influence of soil biogeochemistry on gravel bed underflow composition remains unclear, espec
