Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Nocturnal Incubation Recess and Flushing Behavior by Duck Hens Nesting in Grizzly Island Wildlife Area 2015-2018 Nocturnal Incubation Recess and Flushing Behavior by Duck Hens Nesting in Grizzly Island Wildlife Area 2015-2018
This dataset describes nocturnal incubation recess behavior for mallard and gadwall hens nesting in Grizzly Island Wildlife Area in breeding seasons 2015-2018. It includes the frequency, start time and duration of recesses, and details a method for determining whether a recess was initiated in response to a predator at the nest using nest temperature data. These data support the...
Oenothera deltoides Genotype Data from Contra Costa County, California in 2019 Oenothera deltoides Genotype Data from Contra Costa County, California in 2019
This dataset contains 212 samples from 8 Oenothera deltoides subsp. howellii occurrences, 3 occurrences of the unknown taxon- clade X, and 3 occurrences of related Oenothera deltoides subsp. cognata. Genomic markers were generated from ddRAD loci (Peterson and others, 2012) and analyzed using the Stacks v2.53 (Catchen and others, 2013) pipeline. The genotypes for all samples are provided...
Migration stopover ecology of cinnamon teal in western North America Migration stopover ecology of cinnamon teal in western North America
Identifying migration routes and fall stopover sites of cinnamon teal (Spatula cyanoptera septentrionalium) can provide a spatial guide to management and conservation efforts, and address vulnerabilities in wetland networks that support migratory waterbirds. Using high spatio-temporal resolution GSM-GPS transmitters, we tracked the fall migration of 61 cinnamon teal across western North...
Tidal Wetland Elevation Projections for Five San Francisco Bay Delta Regions Using WARMER-2, 2000-2100 Tidal Wetland Elevation Projections for Five San Francisco Bay Delta Regions Using WARMER-2, 2000-2100
Projections of marsh elevation change with WARMER-2 across five regions of the San Francisco Bay Delta (Cache Yolo, South Delta, North Delta, Central Delta, and Suisun). The model was run across a range of initial elevations for each region and for scenarios of sea-level rise (30, 61, 91, 122, 152, 183, 305 cm by 2100), sediment availability (historic, constant, declining, and increase)...
Western Spadefoot Survey Data in Northern and Central California (2019) Western Spadefoot Survey Data in Northern and Central California (2019)
Species distributions are governed by processes occurring at multiple spatial scales. For species with complex life cycles, the needs of all life stages must be met within the dispersal limitations of the species. Multi-scale processes can be particularly important for these species, where small-scale patterns in specific habitat components can affect the distribution of one life stage...
Catch-Per-Unit-Effort (CPUE), Banding, and Morphometric Data Collected During Nocturnal Mist-Netting Sessions to Evaluate Trends and Variability Among Storm-Petrels of the California Channel Islands (1994-2018) Catch-Per-Unit-Effort (CPUE), Banding, and Morphometric Data Collected During Nocturnal Mist-Netting Sessions to Evaluate Trends and Variability Among Storm-Petrels of the California Channel Islands (1994-2018)
Herein we provide a comprehensive database of storm-petrel (Oceanodroma spp.) morphometrics, banding, and associated mist-netting data collected within Channel Islands National Park (CHIS) from 1994 to 2018. The most abundant storm-petrel species in CHIS, the ashy storm-petrel (Hydrobates homochroa; ASSP), was the focal species in most mist-netting efforts, but data also were recorded...
