This data release contains one table of genetic data (mitochondrial haplotypes and nuclear microsatellite genotypes) used to evaluate utility of two morphological measures (culmen length and plumage color) to correctly identify groups of hunter-harvested dusky (Branta canadensis occidentalis) and dusky-like Canada geese on wintering grounds within the Pacific Flyway of North America...

Land management treatments in sagebrush steppe are an important opportunity to break the annual-grass fire cycle, provided they offer long-lasting resistance to annual-grass invasion and do not burn. However, for BLM areas seeded as part of the Emergency Stabilization and Rehabilitation (ESR) program, one of the largest programs for land management treatments, about 1/4 have at least...

The exotic grass-fire cycle is degrading semiarid rangelands, such as the vast areas of shrub-steppe in North America now invaded by fire-promoting cheatgrass. Chemical- or bio-herbicides are sprayed onto soils to inhibit the invaders, but information on chemical- or bio-herbicide effects on plant communities is limited. We asked how the plant community responded to the bioherbicide...

Protection of intact habitat from the spread of invasive plants is a global priority, especially where the invaders alter wildfire occurrence. Invasion of perennial sagebrush-steppe ecosystems by cheatgrass and other fire-promoting exotic annual grasses (EAGs) is one of the most notorious examples of this problem. Protection and expansion of the remaining intact "core" habitat sagebrush...

Joshua trees (Yucca brevifolia, Y. jaegeriana) are iconic, foundational species of the Mojave and Sonoran Deserts in North America. Due to their ecosystem importance, long generation times, and low resilience to disturbance, these hybridizing sister species are increasingly the focus of conservation efforts. Predicting Joshua tree responses to future climate, along with the extent of...

Diagnostic case-level data recorded by the USGS National Wildlife Health Center (NWHC) in their Laboratory Information Management system (LIMs) and wildlife health information sharing partnership event reporting system (WHISPers). The LIMs database tracks carcass and tissue submissions to the NWHC laboratories, test results, and ultimate cause of death as determined through forensic...

Intertidal microbial biofilms, or microphytobenthos, support estuarine biogeochemical cycling, the physical stability of mudflats, and food webs, particularly those of migratory shorebirds. Photosynthetic biofilms dominated by diatoms, cyanobacteria and chlorophytes represent a significant fraction of biofilm biomass and contain pigments that can be detected with remote sensing. These...

Storage-Extraction_Experiment.csv: These data include the qPCR results (Ct values and copy numbers) of DNA extracted from swab samples inoculated with Pd conidia (1,000, 10,000, or 100,000 conidia), stored at various temperatures (ambient temperature, 4°C, or -20°C), with or without RNAlater® preservative, for various durations (3 days, 1 month, or 3 months), and extracted with either a...

Data shows radioisotope measurements (Pb-210 and Cs-137) of sediment cores from four coastal wetlands along the Chesapeake Bay (one core from each site). Cores were sectioned every 1-2 cm depth.

This data release contains historical SnowModel outputs for the Willow Creek and Big Thompson, CO watersheds and surrounding area. Simulated outputs were produced on a 30 meter (m) geospatial grid and forced using meteorology from the National Land Data Assimilation System (NLDAS-2). These simulations used daily snow water equivalent (SWE) time-series from 13 National Resources...

This data release contains five spreadsheets of information from aerial surveys of the Indigirka River Delta, Russia, in June of 1993 and 1994, data on habitats where nests of Spectacled Eiders (Somateria fischeri) and other species of waterfowl were observed from 1993 to 1995, and genotypic data from feathers collected from eider nests to determine inter-annual rates of return by...

These geospatial datasets describe positions, elevations, and uncertainties for synthetic elevation checkpoints generated across the developed coastline of North Carolina. Two datasets are provided as point shapefiles and American Standard Code for Information Interchange (ASCII) tables, and each contains synthetic checkpoints generated using a time series (1996-2018) of digital...
