The geochemistry and strontium isotope data for Coal Creek Watershed, Colorado, consists of cation, anion, and 87Sr/87Sr isotope values from samples collected at 8 stream location along Coal Creek, samples from two groundwater springs within the watershed, and a shallow subsurface piezometer. All st

Organisms inhabiting seasonal environments must fit their life cycle into a limited time window while also synchronizing periods of resource consumption with timing of resource availability. Introduced non-native species, which often differ in phenology from natives, can alter and expand the seasona

This repository contains three supplemental tables for Veldhuisen et al.'s paper titled "Phylogenetic patterns over sixty-five years of vegetation change across a montane elevation gradient." Tables 1 2 contain species replacements in the Smith Brown (2018) phylogeny for the short and full dataset u

Foliar elements were determined for samples collected in the field during a 2023 survey in Gunnison County, CO that also included paired data collection using an ASD FieldSpec3 spectrometer. Sampling locations were selected based on metal hotspots identified using remote sensing data and foliar elem

This dataset provides site and endmember spectra collected during the 2025 Colorado Headwaters Ecological Spectroscopy Study (CHESS) campaign. The site spectra were collected to help validate airborne hyperspectral data acquired by the National Ecological Observatory Network's aerial observation pla

This dataset includes groundwater and river water elevations and temperature data collected in the East River watershed located in the Upper Colorado River Basin. The data were collected in order to investigate the coupling between hydrology and biogeochemical processes in the floodplain. Data was c

Climate change is driving vegetation shifts in mountain watersheds, with unknown impacts on biogeochemical cycles. We hypothesize that these shifts will reshape soil microbiomes and associated biogeochemical processes. As a part of Lawrence Berkeley National Laboratory (LBNL) Watershed Science Focus

The excess of greenhouse gasses like carbon dioxide in the atmosphere urgently calls for a deeper understanding of existing natural mechanisms for carbon sequestration. Montane meadows act as a critical natural carbon sink, often having the capacity to store much more carbon in their soils than surr

A variety of factors can influence an individual’s antipredator behavior including their group size because simply being around conspecifics may reduce predation risk. Recent work has shown that it is not just being around others, but rather the specific social relationships that individuals have wi

The date of spring snowmelt is advancing in numerous alpine and subalpine ecosystems due to both rising temperatures and reduced snowpack associated with climate change. Snowmelt is a critical source of water for plants in subalpine ecosystems, so changes in snowmelt timing can affect many important

Subalpine ecosystems in Colorado occur between 9,000-11,000ft in elevation and are composed of several species of conifers. The elevation range of each species is slightly different, but they tend to form established communities, such as the Engelmann spruce-subalpine fir community. It has been show

Temperature is one of the limiting factors of life, and it influences an organism’s growth, sexual reproduction, sexual determination, distribution, and metabolism. the interaction between temperature and organisms therefore an essential component of their ecology. Temperature impacts organisms in d

Our study shows that variation in individual phenology affects fecundity in three phenologically distinct montane species, and that pollen limitation may be more influential than conspecific density. Our results suggest that individual-level changes in phenology are important to consider for underst

Individual plants can modify the microenvironment within their spatial neighborhood. However, the consequences of microenvironment modification for demography and species interactions remain unclear at the community scale. In a study of co‐occurring alpine plants, we 1) determined the extent of spec

Abstract Both theory and prior studies predict that climate warming should increase attack rates by herbivores and pathogens on plants. However, past work has often assumed that variation in abiotic conditions other than temperature (e.g. precipitation) do not alter warming responses of plant damage

Abstract Recent reports of insect declines have caused concern among scientists and the public. Declines in insect abundance and biomass are ubiquitous across many climatic zones and have been largely attributed to anthropogenic land use intensification and climate change. However, there are few exa

The Gunnsion Basin Focus area encompasses the upper Gunnsion watershed. The Basin lies entirely on the west side of the Continental Divide. Geographically the area includes most of Gunnsion County, the northern third of Hinsdale County, and the north western third of Saguache County. The total land
