Satellite tracking of sea turtles using Biscayne National Park, 2009-2021 Satellite tracking of sea turtles using Biscayne National Park, 2009-2021
This dataset includes details of loggerhead and green turtles captured and satellite tagged between 2009 and 2021; the turtles presented here have tracking days within Biscayne National Park. A subset of turtles was captured within Biscayne National Park, whereas others were tracked to the study site, and tagged elsewhere. The dataset contains information related to satellite tracking (e...
Chemistry and Flow Data from Headwater Streams Draining Hydrothermally Altered Areas in Colorado Chemistry and Flow Data from Headwater Streams Draining Hydrothermally Altered Areas in Colorado
This U.S. Geological Survey (USGS) data release contains stream water chemistry and streamflow data collected in late August and early September, 2021 from 28 sites located throughout Colorado, USA. The sampled streams all drain high-elevation mountain watersheds in areas where the bedrock is hydrothermally altered and contains abundant sulfide minerals. Most sampled streams are...
Environmental chemistry from selected sites in Lakeport, Lake County, California (version 1.1, August 2023) Environmental chemistry from selected sites in Lakeport, Lake County, California (version 1.1, August 2023)
This data release documents chemical analyses of environmental samples collected by the U.S. Geological Survey (USGS) in Lakeport (Lake County, California) during July 11-12, 2022. Environmental samples were collected at selected sites to assess the effects of lead-based paint on soil chemistry. This sampling was made as part of a broader study to attribute sources of lead in soils in...
Grizzly Bear Space Use in the US Northern Rocky Mountains (ver. 3.0, July 2024) Grizzly Bear Space Use in the US Northern Rocky Mountains (ver. 3.0, July 2024)
Over the past two centuries, persecution and habitat loss caused grizzly bears (Ursus arctos) to decline from a population of approximately 50,000 individuals to only 4 fragmented populations within the continental United States. In recent decades, these populations have increased and expanded in size and range due to collaborative conservation efforts and protections under the...
Assessment of Giant Sequoia Mortality and Regeneration within Burned Groves in Sequoia and Kings Canyon National Parks (ver. 4.0, February 2026) Assessment of Giant Sequoia Mortality and Regeneration within Burned Groves in Sequoia and Kings Canyon National Parks (ver. 4.0, February 2026)
Provided are data containing condition assessments on individual giant sequoia (Sequoiadendron giganteum; SEGI) stems and post-fire regeneration counts within Board Camp, Suwanee, New Oriole Lake, and a subset of Redwood Mountain groves of Sequoia and Kings Canyon national parks, respectively. Stem data contain condition-related attributes (e.g., spatial location, diameter breast height...
Data relating to the development of a quantitative PCR assay for detecting Northwest salamander (Ambystoma gracile) in environmental DNA samples Data relating to the development of a quantitative PCR assay for detecting Northwest salamander (Ambystoma gracile) in environmental DNA samples
The data support a study that describes the development and validation of a primer and probe based quantitative PCR (qPCR) assay for use with environmental DNA to detect Northwest salamander (Ambystoma gracile), a species endemic to the temperate Pacific coastal region of North America. The metadata includes qPCR quantification cycle (Cq) values from testing the A. gracile assay on DNA...
