Genetic and Habitat Data for Plantago ovata in the Mojave Desert Genetic and Habitat Data for Plantago ovata in the Mojave Desert
These datasets were developed to represent the genetic diversity, population structure, and geographic distribution of Plantago ovata in the Mojave Desert. This data release consists of two tab-delimited text files representing the genetic diversity and structure of Plantago ovata (.genepop and .vcf), and two raster spatial datasets (GeoTIFF) reflecting predicted habitat for the species...
Post-fire conifer regeneration observations for National Forest land in California (2009 - 2017) Post-fire conifer regeneration observations for National Forest land in California (2009 - 2017)
This data consists of presence/absence observations for post-fire conifer regeneration. The data also includes estimates of plot-level topography (slope, aspect), relativized differenced normalized burn ratio (RdNBR), post-fire climate, live basal area, and seed rain. These data support the following publication:
Hair and blood total mercury concentrations in raccoons and striped skunks from Suisun Marsh 2016 to 2019 Hair and blood total mercury concentrations in raccoons and striped skunks from Suisun Marsh 2016 to 2019
Total mercury concentrations were determined in hair and whole blood of raccoons and skunks in Suisun Marsh from 2016 to 2019. Individual skunks and raccoons were identified by a unique identifier (Animal_ID) and some animals were sampled multiple times. This dataset includes animal sex, age class, the date the sample was collected, animal body mass, head length, and head-to-torso length...
Invasive Plant Cover in the Mojave Desert, 2009 - 2013 (ver. 2.0, April 2021) Invasive Plant Cover in the Mojave Desert, 2009 - 2013 (ver. 2.0, April 2021)
We assessed the impacts of co-occurring invasive plant species on fire regimes and postfire native communities in the Mojave Desert, western USA by analyzing the distribution and co-occurrence patterns of three invasive annual grasses known to alter fuel conditions and community structure: Red Brome (Bromus rubens), Cheatgrass (Bromus tectorum), and Mediterranean grass (Schismus spp...
SUTRA model used to evaluate the effects of groundwater withdrawal and injection, Kaloko-Honokohau National Historical Park, Hawaii SUTRA model used to evaluate the effects of groundwater withdrawal and injection, Kaloko-Honokohau National Historical Park, Hawaii
A three-dimensional, variable-density solute-transport model (SUTRA) was developed to evaluate the effects of three selected withdrawal/injection scenarios on salinity of groundwater (as simulated at damselfly anchialine-pool habitat) and discharge of freshwater to the nearshore environment of Kaloko-Honokohau National Historical Park (KAHO), Hawaii. A base model was constructed using...
Long-term database of historical, current, and future land cover for the Delaware River Basin (1680 through 2100) Long-term database of historical, current, and future land cover for the Delaware River Basin (1680 through 2100)
The USGS's FORE-SCE model was used to produce a long-term landscape dataset for the Delaware River Basin (DRB). Using historical landscape reconstruction and scenario-based future projections, the data provided land-use and land-cover (LULC) data for the DRB from year 1680 through 2100, with future projections from 2020-2100 modeled for 7 different socioeconomic-based scenarios, and 3...
