It is unclear how environmental change influences standing genetic variation in wild populations. Here, we characterized environmental conditions that protect vs. erode polymorphic chemical defenses in Boechera stricta (Brassicaceae), a short-lived perennial wildflower. By manipulating drought and h

This U.S. Geological Survey (USGS) data release contains data from stream water, groundwater, and stream sediment samples collected in August 2023 in the East Mancos River watershed in southwestern Colorado. Data were collected as part of a study aimed at identifying sources of elevated metal concen

The ocean absorbs one quarter of the global CO2 emissions from human activity. The community-led Surface Ocean CO2 Atlas (www.socat.info) is key for the quantification of ocean CO2 uptake and its variation, now and in the future. SOCAT version 2025 has quality-controlled in situ surface ocean fCO2 (

From fall 2021 through summer 2023, NOAA and research partners conducted a field study (SPLASH - the Study of Precipitation, the Lower Atmosphere and Surface for Hydrometeorology). This field study established a state-of-the-art observing network in the East River watershed of the Colorado mountains

High alpine ecosystems have heterogeneous topography that provides microclimatic niches for species to inhibit. Due to climate change, alpine ecosystems are experiencing shifts in snowpack amount, snowmelt timing, and growing season lengths resulting in phenological and abundance responses within ec

Climate change is altering water availability in subalpine ecosystems. Shifts in snowmelt timing and summer monsoonal precipitation, which alter soil moisture, have the capacity to elicit plastic responses in plants. Plasticity in floral traits such as nectar production and flower color can impact p

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

Black bears in the Colorado Rocky Mountains forage for western thatching ants as a food source. However, there is little knowledge about the nutritional benefit of ants for black bears, particularly with regard to changes in nutritional value during the ant life cycle. From late spring to mid-summer

Forest ecology research is being revolutionized with the advent of remote sensing. Remote sensing is more accurate and reliable than previous methods for assessing forest dynamics, so it is important to generate workflows for assessing them. The forests of the Gothic townsite are an underutilized su

The decomposition of animal carrion, particularly small animals that are used as a breeding resource for carrion insects, is little studied but is likely to be a major component of nutrient cycling in many ecosystems. This project focuses on how carrion insects affect small vertebrate carrion decomp

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

Density dependence—the impact of neighbors on the survival, growth, or reproduction of individuals—strongly impacts the size and dynamics of populations. However, it is unknown how the effects of density dependence vary across species ranges, which will be integral knowledge in the face of climate c

Despite the ecological significance of prominent coniferous forests surrounding RMBL, there are few comprehensive studies on these systems, particularly regarding transpiration dynamics. Their critical role in carbon sequestration, microclimate dynamics, and water resource management in the Upper Co

The study of plant-insect interactions and pollination has just begun to scratch the surface of the microbes that inhabit many of the surfaces involved in these interactions. While most microbial studies have focused on the roles of obligate nectar yeasts in mediating pollinator behavior and fitness

Predator-prey interactions extend beyond direct predation and can influence prey behavior and habitat use. This “ecology of fear” has been studied in a wide variety of taxa, and differences in perceived predation risk have been demonstrated to impact species coexistence. Previous research (Smith 199
