Thin section images of hand samples and drill core from mafic to ultramafic rocks (ver 2.0, August 2025) Thin section images of hand samples and drill core from mafic to ultramafic rocks (ver 2.0, August 2025)
These datasets include photographic images of thin sections created from hand samples and drill core collected from mafic to ultramafic rocks from different locations across the U.S., shapefiles representing the locations of the hand samples and/or drill core collars, and images showing examples of the approximate scale on the thin section images. The samples were collected in order to...
Extrapolated Offshore Occupancy Predictions for Three Bat Species Extrapolated Offshore Occupancy Predictions for Three Bat Species
We generated an extrapolated surface of predicted occupancy values offshore for the little brown bat (Myotis lucifugus), northern long-eared bat (Myotis septentrionalis), and tri-colored bat (Perimyotis subflavus). Values were generated for each grid cell in the Continental United States (CONUS) Grid-Based Offshore Sampling Frame which extends from coastal areas (i.e., 10 kilometer [km]...
Hawaiʻi Volcanoes National Park Effects of Felling and Tarping Trees on ROD Viability and Ambrosia Beetle Activity 2022-2023 Hawaiʻi Volcanoes National Park Effects of Felling and Tarping Trees on ROD Viability and Ambrosia Beetle Activity 2022-2023
Felling and tarping is a common management strategy for ʻōhiʻa lehua trees (Metrosideros polymorpha) infected with rapid ʻōhiʻa death (ROD) caused by Ceratocystis lukuohia and Ceratocystis huliohia fungal pathogens and spread via ambrosia beetles (Coleoptera: Curculionidae). In order to understand how tarping may decrease fungal viability or the spread of viable beetle frass, this study...
Island of Hawai'i Ambrosia Beetle Trapping Data and Locations of Suspected Ceratocystis-positive ʻōhiʻa at Two Sites, 2021-2022 Island of Hawai'i Ambrosia Beetle Trapping Data and Locations of Suspected Ceratocystis-positive ʻōhiʻa at Two Sites, 2021-2022
This data release includes data and metadata documenting 1) ambrosia beetle (Coleoptera: Curculionidae) species caught in multi-panel traps within ʻōhiʻa lehua (Metrosideros polymorpha) dominated forests in Hawaiʻi Volcanoes National Park as well as results from culturing Ceratocystis lukuohia or Ceratocystis huliohia, the fungi that cause rapid ʻōhiʻa death (ROD), from these traps, 2)...
Chub whole body calorimetry, feeding trial ration, and chironomid weights to develop inputs for a bioenergetics community model Chub whole body calorimetry, feeding trial ration, and chironomid weights to develop inputs for a bioenergetics community model
A series of laboratory studies were conducted to understand Sicklefin and Shoal Chub feeding rates and maximum ration. Data included determination of Chironomid weight, estimated by taking weights and counts of approximately 5 grams of laboratory cultured chironomids. Chub maximum ration was determined by finding the feeding rate of dry commercial fish food that thar resulted in complete
Data release for mortality events in Yuma myotis (Myotis yumanensis) due to white-nose syndrome in Washington, USA, 2020-2024 Data release for mortality events in Yuma myotis (Myotis yumanensis) due to white-nose syndrome in Washington, USA, 2020-2024
The impacts of white-nose syndrome (WNS) on many bat species in eastern North America have been well-documented due to the length of time that the causative agent, Pseudogymnoascus destructans (Pd), has been present and the ability to monitor bat hibernacula in that region. However, the disease outcomes for bat species in western North America are less known because of the more recent...
