Daily water stable isotopes, transpiration, and matrix potential data for an aspen and engelmann stand in the East River Watershed

We provide daily stable isotope (2H & 18O) ratios in soil water and xylem (plant stem) water, as well as the sap flow (transpiration) and the soil's matric potential at a forested site near Gothic, Colorado, in the East River catchment. We measured the stable isotopic composition of the transpi

Seasonal manganese transport in the hyporheic zone of a snowmelt-dominated river (East River, Colorado)

Manganese (Mn) plays a critical role in river water quality since Mn-oxides serve as

Does road dust have an effect on nectar production in <i> pomopsis aggregata </i>?

Road dust has potential impacts on plant metabolism and reproduction even in small amounts. Dust is everywhere and is increasing due to human influence, this has the potential to reduce overall plant pollination worldwide. Since dust is roughly the size of a grain of pollen, it might possibly clog t

Seasonal Progression of Algal Development and Quality in Streams that Vary in Timing of Springtime Peak Flow

Climate driven shifts in stream hydrology from early, rapid snowmelt may have implications for algae growing within high altitude montane streams. Peak flow scours the benthic layer and clears senesced algal growth and sediment, effectively priming the substrate for new algal growth following peak f

Mapping the range shifts of East River Valley caddisflies <i> (Trichoptera) </i>

Range shifts occur when all individuals of a species or population move from a previously- habitable area to a newly-habitable area in response to changing environmental conditions. Climate- induced range shifts are well-documented for certain regions, biomes, and taxa, but large knowledge gaps exis

Trap behavior of <i> Zonotrichia leucophrys oriantha </i> at different elevations in the West Elk Mountains, Colorado

High-alpine ecosystems are particularly vulnerable to climate change. Thus, many ecosystem patterns are shifting due to warming temperatures, extreme weather events, and seasonal changes. This becomes an issue for birds that breed and live in high-elevation environments, as they may not be able to c

Impacts of the invasive species <i> Linaria vulgaris </i> on soil ecology and native plant biodiversity

Invasive species are a major threat to biodiversity. Invasive plant species can alter ecosystems by outcompeting natives, lowering biodiversity, and change soil ecology. Additionally, invasive species can be costly to manage. Linaria vulgaris, a non-native noxious weed from Europe and Asia, was used

Volatile organic compounds as signals for pollinators and their consistency across years

Volatile organic compounds (VOCs) are emitted by every part of a plant and are believed to work as possible olfactory signals, drawing in pollinators and antagonists. This study was designed to address whether VOCs served as a signal to pollinators, indicating the size of the nectar reward. This par

Niche breadth changes in response to environmental perturbation: the impact of early snowmelt on subalpine plant-pollinator specialization

With global climate change, we observe phenological changes across all ecosystems. In the Colorado Rocky Mountains, warming is resulting in lower snowpack and earlier spring melt. Since plants use snow melt timing as a cue to start growing, climate change is implicated in accelerated bloom time and

Effects of avalanches on rodent populations

Ecologists are interested in studying the factors that affect the abundance of a species. Disturbances, such as avalanches, could affect the populations of small mammals. Live trapping has been a traditional method to study abundances of small mammals; however, it has some downsides. A new, non-inva

Exploring mechanisms explaining coexistence patterns of <i> Rhyacophila </i> species (Trichoptera) in streams near the Rocky Mountain Biological Laboratory

Coexistence of closely related species can be explained by a number of biotic and abiotic factors. In Trichoptera (caddisflies), the patterns of coexistence of the species Rhyacophila in streams near the Rocky Mountain Biological Laboratory (RMBL) has been tracked for 43 years. This study is a conti
