Over time, barrier islands may become eroded and experience land loss, which require management actions to restore island integrity. The process of restoring barrier islands can create new habitats but also alter existing habitats, which can impact the organisms depending on coastal habitats, such as the Endangered Species Act-listed Piping Plover (Charadrius melodus). Therefore, we...

Thucholites are unique organic features from igneous and sedimentary rocks composed of a U-C-rich interior enclosed by an organic outer shell. Here, we evaluated thucholites from the Ediacaran Salt Range Formation of the Upper Indus Basin in Pakistan using field emission scanning electron microscopy (FESEM) and nanoscale secondary ion mass spectroscopy (NanoSIMS). The thucholites can be...

Grasslands are an imperiled ecosystem, and grassland bird abundance is declining across North America. One of the strongest drivers for these declines is woody plant encroachment of grasslands. In the Great Plains and Sagebrush biomes of North America, spatial covariance—a remote sensing metric for tracking boundaries between vegetation types—is emerging as a new method to identify and...

The U.S. Geological Survey (USGS) deployed a series of oceanographic instruments at Madeira Beach, Florida configured to measure water levels, temperature, waves, and three-dimensional flow velocities throughout the water column. The instruments include (1) Spotter wave buoys with Smart Mooring (2) RBR pressure loggers, and (3) RDI Sentinel-V Acoustic Doppler Current Profilers (ADCP)...

The U.S. Geological Survey (USGS) conducted a study in cooperation with the Sonoma County Water Agency to assess the water resources of the SRPW and develop tools to better understand the groundwater and surface-water systems in the watershed. The foundation of these tools is the development and application of the Santa Rosa Plain hydrologic model (SRPHM) using GSFLOW to simulate...

Ratings are used for a variety of reasons in water-resources investigations. The simplest rating relates discharge to the stage of the river. From a pure hydrodynamics perspective, all rivers and streams have some form of hysteresis in the relation between stage and discharge because of unsteady flow as a flood wave passes. Simple ratings are unable to represent hysteresis in a stage...

In this experiment at Waiākea Forest Reserve, we tested the efficacy of the semiochemical repellent, verbenone, in commercial SPLAT® Verb formulation, at protecting healthy and rapid ʻōhiʻa death-Ceratocystis infested ʻōhiʻa from ambrosia beetle colonization in the 2022 and 2023 field seasons. Data files include 1) raw beetle counts, 2) individual tree information, and 3) verbenone mean...

We compared genetic diversity and body condition indices among two source locations in Catron County, New Mexico (Whitewater Creek and Middle Fork Gila) and the recipient population (Saliz Creek) to evaluate individual- and population-level fitness responses related to the admixture of gene pools following the the translocation of Mogollon Narrow-headed Gartersnakes (Thamnophis...

This dataset provides estimates of the proportion of basal area that survived along with burn severity indices for 585 plots following four large fires in California, including the Carr (2018), Dixie (2021), Caldor (2021), and KNP (2021) fires.

This data file contains observations recorded during field surveys of post-fire vegetation in the 2021 Caldor and 2022 Mosquito Fires in the Sierra Nevada of California. The surveys were performed in summer 2023. All tree species were surveyed and treated the same.

The monitoring program at San Nicolas Island (SNI) was conceived in anticipation of the potential reintroduction of southern sea otters to the island. Subtidal monitoring was initiated in autumn of 1980 at six sampling sites positioned around the island to sample communities exposed to a range of wave exposures and other oceanographic conditions. Three additional sites were subsequently...
