Solute chemistry for streams draining geomorphic features and varying land cover gradients in the East River watershed, Colorado
This dataset contains solute chemistry data and GPS coordinates for surface water samples collected in the East River watershed in the Elk and West Elk Ranges of Colorado from August 3rd through August 11th, 2022. Samples were collected from streams and groundwater seeps as part of a comprehensive a
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

Effects of herbivory by a translocated butterfly on plant size and seed set of Lonicera involucrata
Assisted migration consists of the introduction of a species to previously inhabited areas or to new suitable regions. Such introductions have been touted as a viable tool for conserving earth's biodiversity. However, both the likely success of assisted migrations and the impacts on local communitie
Upland Vegetation and Soils Monitoring for the Northern Colorado Plateau Network: 2009-2023 - Data Package
Uplands are land areas lying above the elevation where flooding generally occurs—areas found beyond riparian zones. Uplands represent the vast majority of land area in the Northern Colorado Plateau Network (NCPN), and include rock outcrops, badlands, shrublands, grasslands, woodlands, and forests. U
Data from: Phylogeny does not predict the outcome of heterospecific pollen-pistil interactions in a species-rich alpine plant community
Premise: Co-occurring plant species that share generalist pollinators often exchange pollen. This heterospecific pollen transfer (HPT) impacts male and female reproductive success through pollen loss and reductions in seed set, respectively. The resulting fitness cost of HPT imposes selection on rep
Decomposing an elevational gradient in predation by insectivorous birds
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, variation in
NEON AOP Survey of Upper East River CO Watersheds: Waveform LiDAR Binary Data
The waveform Light Detection and Ranging (LiDAR) data in this package were generated through a National Ecological Observatory Network Airborne Observation Platform (NEON AOP) acquisition over watersheds of interest surrounding Crested Butte, Colorado. The remote sensing imagery acquired by the NEON

Quantifying the effects of pollen load and heterospecific pollen ratio on the species <i>Delphinium barbeyi</i> (Ranunculaceae)
To date there are few studies that have carefully studied the impact that varying pollen quantity and proportion of heterospecific pollen has on reproductive rate of a flowering plants. My project aimed to assess the relationship between pollen quantity and composition on the subalpine larkspur, Del
The effects of floral traits on the behaviors of pollinators and pre-dispersal seed predators in a gynodioecious species, <i>Polemonium foliosissimum</i>.
In order to maintain in the population, female plants of gynodioecious species must compensate for their loss of male function. Understanding how mutualist pollinators and antagonists such as seed predators respond to floral cues presented by female and hermaphrodite flowers in ways that could contr
How do riparian songbirds (Passerines) coexist? Effects of vegetative structural complexity on habitat selection in willow (<i>Salix</i> spp.)
The diversity of avian species and their coexistence in riparian habitat has become increasingly significant in the face of rapidly decreasing vegetation along hydric areas, primarily due to pollution, urbanization, overgrazing, and climate change. The complex and rare riparian habitat system is pri
Investigating the impact of pollinator- and seed predator-mediated selection on floral traits in an <i>Ipomopsis aggregata</i> and <i>I. tenuituba</i> (Polemoniaceae) hybrid zone
While the impacts of pollinator species on selection for floral traits in angiosperms are relatively well-studied, less is known about the contributions of herbivores towards selection on floral traits. We investigated the relationship among a variety of floral traits (including volatile emissions a
Plot-scale evidence of tundra vegetation change and links to recent summer warming
Global assessment of experimental Climate warming on tundra vegetation: heterogeneity over space and time
Sarah C. Elmendorf,1* Gregory H. R. Understanding the sensitivity of tundra vegetation to climate warming is critical to forecasting future Henry,1 Robert D. Hollister,2 Robert G. biodiversity and vegetation feedbacks to climate. In situ warming experiments accelerate climate change on a Björk,3 An
X-ray imaging of leaf venation networks
Summary Leaf venation networks mediate many plant resource fluxes and are therefore of broad interest to research questions in plant physiology, systematics, paleoecology, and physics. However, the study of these networks is limited by slow and destructive imaging methods. X‐ray imaging of leaf vein
Spatial distribution of mule deer (<i>Odocoileus hemionus</i>): Effects of plant palatability and habitat structure
Scientists at the Rocky Mountain Biological Laboratory (RMBL) have recorded more mule deer (Odocoileus hemionus) activity density within the Gothic town site relative to outside the town site. One hypothesis to account for increased deer activity in Gothic is that coyotes, who prey on deer fawns, av
