Amplicon sequencing of pollen foraged by multiple bee species in units of the National Park Service, National Capital Region, 2021-2022 Amplicon sequencing of pollen foraged by multiple bee species in units of the National Park Service, National Capital Region, 2021-2022
This study generated genetic 'metabarcode' data using high-throughput sequencing to characterize pollen foraging behavior of pollinating bee species on managed field habitat within units of the National Park Service. Specimens were collected within parks of the National Capital Region from 2021-2023 and subsequently identified to species or genus. DNA was then extracted from specimens...
Amplicon sequencing of pollen foraged by Bombus affinis for compositional analysis, 2021-2023 Amplicon sequencing of pollen foraged by Bombus affinis for compositional analysis, 2021-2023
This study generated genetic 'metabarcode' data using high-throughput sequencing to characterize pollen foraging behavior of the endangered rusty-patched bumblebee, Bombus affinis. Pollen samples were collected primarily from forest meadow habitats in the Appalachian piedmont of the eastern United States, specifically within the states of Virginia and West Virginia. Three additional...
Imagery, sediment collection, photogrammetry, and meteorological data from July 2023 to November 2024, Grand Falls Dune Field, Arizona Imagery, sediment collection, photogrammetry, and meteorological data from July 2023 to November 2024, Grand Falls Dune Field, Arizona
Grand Falls dune field (GFDF) is located on the Navajo Nation, ~70 km NE of Flagstaff, AZ. This active dune field displays a range of morphologies, including barchans, dome dunes, smaller dunes, and ripples, and is bimodal both in mineralogical composition and grain size distribution. The felsic component is likely derived from the Little Colorado River, and the mafic component (basaltic...
Scientific studies that document invasive grass impacts on fire and methods to control their spread in the Intermountain West, USA from 1985 to 2023 Scientific studies that document invasive grass impacts on fire and methods to control their spread in the Intermountain West, USA from 1985 to 2023
Many non-native invasive grass species increase wildfire activity and recover more quickly than native species. This invasive grass-fire cycle has severe negative consequences for ecosystems, creating a need to understand how different invasive grass species alter fuel characteristics and fire behavior, as well as effective treatments to reduce their spread. We reviewed and compiled...
Guam, Mariana swiftlet nest behavior, 2023-2024 Guam, Mariana swiftlet nest behavior, 2023-2024
The yǻyaguak (Mariana swiftlet; Aerodramus bartschi) is an endangered cave-nesting species historically found on Guam and the southern Mariana Islands, Micronesia. The population on Guam has been severely impacted by the introduction of the brown treesnake (Boiga irregularis). We analyzed nest attendance behavior derived from near-infrared videography at the colonies at Mahlac and...
Simulated lahar extents and dynamics in the Middle Fork Nooksack River drainage, resulting from hypothetical landslide sources on the western summit of Mount Baker, Washington Simulated lahar extents and dynamics in the Middle Fork Nooksack River drainage, resulting from hypothetical landslide sources on the western summit of Mount Baker, Washington
This data release contains model input and postprocessed model output from a set of numerical simulations of hypothetical lahars initiated on Mount Baker, Washington. We constructed a set of landslide sources near the western summit of Mount Baker and simulated their initiation and downslope evolution into long-runout lahars in the Middle Fork of the Nooksack River. These simulations...
