Tree loss is increasing rapidly due to drought- and heat-related mortality and intensifying fire activity. Consequently, the fate of many forests depends on the ability of juvenile trees to withstand heightened climate and disturbance anomalies. Extreme climatic events, such as droughts and heatwaves, are increasing in frequency and severity, and trees in mountainous regions must contend...

Continuous water quality sensor data were collected at USGS 292939089544400 Wilkinson Bayou cutoff north of Wilkinson Bay, LA gage. Field water quality measurements were collected using a YSI EXO2 water quality sonde equipped with a data logger to capture hourly data using sensors for measuring water temperature, specific conductance, salinity, pH, oxidation and reduction potential (ORP)

We used mesocosms to evaluate the effects of drought on Nothonotus moorei (Yellowcheek Darter) and Nothonotus juliae (Yoke Darter) survival, growth, and behavior. Survival was low and did not differ between treatments. Yoke Darters gained mass in control treatments, whereas Yellowcheek Darters did not differ between treatments. Habitat-use varied between treatment and species, with...

This geologic database is a digitized version of the original 1:24,000-scale analog geologic map titled "Preliminary geologic map of the Monkeys Head quadrangle, Mohave and La Paz Counties, Arizona", published by the U.S. Geological Survey (USGS) in 1988. The Monkeys Head 7.5-minute quadrangle is located at the confluence of the Colorado and Bill Williams Rivers in westernmost Arizona...

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...

The data being released were part of a project funded by the Section 40804 Ecosystem Restoration of the Bipartisan Infrastructure Law (PL-117-58) in support of advancing a national revegetation effort. Data included are from a series of DNA degradation experiments targeting the mitochondrial 16S rRNA gene of the European honeybee (Apis mellifera). This study sought to determine how...

These videos show a pair of common terns usurping a least tern nest with chicks. These data support a paired USGS authored manuscript.

This data set is from a study examining the flow of per- and polyfluoroalkyl substances (PFAS) through food webs. The data are PFAS concentrations in gastrointestinal contents of tree swallows.

USGS researchers and technicians comprehensively surveyed each of 150 talus patches for evidence of American pika (Ochotona princeps) occurrence. Occurrence status at each patch was classified as either no pika evidence whatsoever, former pika occurrence, or current pika occurrence. Dataset also includes latitude and longitude, as well as mean elevation of the patch and the surveyor...

This U.S. Geological Survey (USGS) data release includes necessary information and data to support the analysis and interpretations of nutrient loading and sources of nitrogen in the associated companion USGS Scientific Investigations Report. This data release includes (1) summary statistics for discrete water-quality data collected at eight water-quality-monitoring stations in the...

This dataset records Cladophora and associated benthic algae, collectively the Cladophora community or submerged aquatic vegetation (SAV), biomass collected during the growing season of 2023 at stations located along the U.S. shoreline of Lakes Michigan, Huron, Erie, and Ontario. It also records a variety of supporting data collected at Cladophora measurement stations. These supporting...

Mine waste, including mill tailings, could host substantial critical mineral resources. Developing an understanding of the mineral hosts and occurrence of critical minerals in mine waste is essential to evaluating their resource potential. Volcanogenic massive sulfide (VMS) and sedimentary-exhalative (SEDEX) deposits are important global sources of copper, zinc, lead, gold, and silver...
