We designed and implemented snake-resistant nestboxes and tested their efficacy as a conservation tool by comparing nest survival in nestboxes to natural nests for Aplonis opaca (Såli, Micronesian Starling) on Guam. During 2016-2018, we monitored 340 nest attempts by 40 A. opaca pairs nesting in nestboxes and 53 attempts by 32 pairs nesting in natural nests (outside of nestboxes), for a...

This dataset consists of 424 paleomagnetic sites from Newberry Volcano. 15 sites were analyzed at the natural remanent magnetization level, 256 sites were analyzed with blanket demagnetization, and 153 sites were analyzed with modern stepwise demagnetization protocols. 412 sites yield acceptable paleomagnetic data.

Heavy fog was hypothesized to interfere with flight of waterfowl by obscuring visibility and cause waterfowl to fly more in search for habitat below, which in turn, is likely to increase bioenergetic (caloric) cost related to increased time flying. The data sets include variables used to analyze the relationship between fog characteristics (occurrence, density, and longevity) and flight...

The following report summarizes the dating results from sedimentary deposits sampled by the USGS Geologic Harzards Team and analyzed at the USGS Luminescence Geochronology Laboratory. Within this report, we detail the methodology used by the USGS Luminescence Geochronology Laboratory to obtain ages including sample preparation methods, luminescence measurement, equivalent dose...

The 1966-2024 North American Breeding Bird Survey (BBS) dataset contains avian point count data for more than 700 North American bird taxa (species, races, and unidentified species groupings). These data are collected annually during the breeding season, primarily in June, along thousands of randomly established roadside survey routes in the United States and Canada. Routes are roughly...

This data release contains principal facts of gravity measurements by previous studies and collected by the U.S. Geological Survey in 1994-2023 and a compilation of existing and new density and magnetic susceptibility data in northeastern California. Gravity data are processed to isostatic anomalies using reduction densities of 2670 and 2200 kilogram/cubic meter. This region is at the...

Snake fungal disease, which is caused by the fungal pathogen Ophidiomyces ophidiicola, is associated with severe skin infections and mortality in individual snakes. However, little has been described regarding how disease severity and impacts vary by snake populations and species. We describe mortality in rainbow snakes in Virginia, USA, linked to snake fungal disease. This data set...

Increasing trends of coral mortality is a challenge to coral reef management worldwide, and a need exists to identify the causes and pathways involved. Pathology is useful to help decipher potential causes of mortality in animals, because it illuminates agents associated with lesions and gives insights on the nature of how a host responds to said agents. To better understand the nature...

This U.S. Geological Survey data release consists of vector and raster geospatial datasets used to determine the volume of sediment in Pahranagat Wash, impounded above Arrow Canyon Dam, in northern Moapa Valley, Nevada. The data release includes: 1) a raster dataset of a 1-meter resolution digital elevation model (DEM) of the study area created using a lidar (light detection and ranging)...

Two dams on the Elwha River, Washington State, USA trapped over 20 million m3 of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a delta system...

Sagebrush songbird fledglings (Brewer's sparrow, sagebrush sparrow, and sage thrasher) were measured and tracked using radio telemetry in Pinedale, Wyoming during 2021-2023.

This data release is composed of several datasets that contain water, sediment, and rock chemistry results from samples collected within and near the Florida River watershed in southern Colorado. Samples were collected during three sampling events in April 2022, May 2022, and August–September 2022. The data will aid investigators in understanding the sources and seasonality of aluminum...
