Microsatellite genotypes of Bombus occidentalis specimens (including Bombus mckayi) from 1960 to 2020 Microsatellite genotypes of Bombus occidentalis specimens (including Bombus mckayi) from 1960 to 2020
This dataset consists of the microsatellite genotypes, collection data, and ownership data for 1461 specimens of Bombus occidentalis. The dataset includes both recognized subspecies, Bombus occidentalis occidentalis and Bombus occidentals mckayi. The subspecies have since been elevated to species status and are currently described as Bombus occidentalis and Bombus mckayi. The specimens...
Microscopic Images of Leonardite and Humate Biochar: Using Reflected Light Microscopy in Biochar Characterization Microscopic Images of Leonardite and Humate Biochar: Using Reflected Light Microscopy in Biochar Characterization
Biochar is a carbon-rich substance that is derived through the thermochemical conversion of biomass. Biochar is recognized for its significance in environmental applications and sustainable agriculture. In an effort to comprehend how the source material and pyrolysis parameters influence its properties, reflected light microscopy is being used to produce microscopic images for analysis...
Mid-Holocene-to-present Modeled (ca., 7,000 to 100 cal. BP) and Reconstructed (ca., 5,900 to 5,436 cal. BP) Temperature for the High-Elevations of the Greater Yellowstone Ecosystem: Derived from a Transient Climate Model and Whitebark Pine Tree-rings Mid-Holocene-to-present Modeled (ca., 7,000 to 100 cal. BP) and Reconstructed (ca., 5,900 to 5,436 cal. BP) Temperature for the High-Elevations of the Greater Yellowstone Ecosystem: Derived from a Transient Climate Model and Whitebark Pine Tree-rings
In the Rocky Mountains of the Greater Yellowstone Ecosystem (United States), recent melting at a high-elevation (3,091 m asl) ice patch exposed a mature stand of whitebark pine (Pinus albicaulis) trees located ~180 m above modern treeline dating to the mid-Holocene (c. 5,900-5,436 cal y BP +- 51 y). From this subfossil wood record, we contextualize the recent magnitude of warming...
Midway Atoll survey of avian malaria prevalence in passerines 2023 Midway Atoll survey of avian malaria prevalence in passerines 2023
Non-native passerines, common canary (Serinus canaria; n=24) and the common myna (Acridotheres tristis; n=19), were captured by US Fish and Wildlife Service Biologists on Sand Island, Midway Atoll, and had a blood sample taken to test for avian malaria (Plasmodium relictum) infection. Blood samples were analyzed for the presence of avian malaria DNA using a Realtime PCR (qPCR) assay. No...
Mineralogy, chemistry and isotope composition of silica sinter deposits from the Upper Geyser Basin, Yellowstone National Park (ver. 2.0, April 2021) Mineralogy, chemistry and isotope composition of silica sinter deposits from the Upper Geyser Basin, Yellowstone National Park (ver. 2.0, April 2021)
Summary: Siliceous sinter samples were collected from multiple geysers in the Upper Geyser Basin of Yellowstone National Park in 2018. These silica sinter samples were collected and analyzed as a part of a multi-year research investigation into the age and geochemistry of hydrothermal features in the Upper Geyser Basin. Samples were collected along the stratigraphy of each feature. From...
Minnesota Point beach topography and near-shore bathymetry surveys of Lake Superior, Duluth, MN, August - November 2022 (ver. 2.0, September 2024) Minnesota Point beach topography and near-shore bathymetry surveys of Lake Superior, Duluth, MN, August - November 2022 (ver. 2.0, September 2024)
Topobathy was surveyed during the fall of 2022 for two locations along Minnesota Point, where past beach nourishment (dredge materials) were placed. These topobathymetric surveys of Minnesota Point and Lake Superior are repeat surveys that will be used evaluate movement of placed material and overall change of near-shore bathymetry. The data was acquired using a lidar sensor, and single...
Miscellaneous Microtremor Array Datasets from the Puget Lowland, Washington State Miscellaneous Microtremor Array Datasets from the Puget Lowland, Washington State
Abstract: We compile three microtremor array datasets acquired in three campaigns in the Seattle and Tacoma basins, Washington State. These datasets were acquired between 2007 and 2018. Dataset 1 includes seven sites in the western Seattle and Tacoma basins acquired to image shear-wave velocity (Vs) in the upper 1 km that are suitable for analysis with microtremor methods not requiring...
Mississippi River fishes collected by a suite of entanglement and entrapment gears; 2020-2023 Mississippi River fishes collected by a suite of entanglement and entrapment gears; 2020-2023
Black Carp (Mylopharyngodon piceus) were imported to the United States for use as a biological control in aquaculture and have since escaped with reproducing populations in the wild. Habitat use and capture of this species has not been well documented in the wild, thus questions about catchability by gears and habitats are present. This dataset represents sampling effort to capture Black...

Model Archive and Hydraulic and Fluvial Egg Drift Simulator (FluEgg) Results for Simulations of Grass Carp Eggs and Larval Drift in the Lower Sandusky River, Ohio Model Archive and Hydraulic and Fluvial Egg Drift Simulator (FluEgg) Results for Simulations of Grass Carp Eggs and Larval Drift in the Lower Sandusky River, Ohio
The U.S. Geological Survey simulated the drifts of grass carp eggs in the lower Sandusky River, Ohio, using the Fluvial Egg Drift Simulator (FluEgg) (Garcia and others, 2013; Zhu, 2019).
