Holocene foraminifera, climate, and decelerating rise in sea level on the mud patch, southern New England continental shelf Holocene foraminifera, climate, and decelerating rise in sea level on the mud patch, southern New England continental shelf
We examined Holocene benthic foraminiferal biofacies, % planktonic foraminifera, and lithofacies changes from New England mud patch cores and present a relative sea-level (RSL) record to evaluate evolution of these rapidly deposited (30–79 cm/kyr) muds. Sandy lower Holocene sections are dominated by Bulimina marginata. The mud patch developed from 11–9 ka as RSL rise slowed from 10 to 7...

Detrital zircons and the magmatic history of Viti Levu, Fiji Detrital zircons and the magmatic history of Viti Levu, Fiji
We integrate the existing detrital zircon data from multiple modern river sediment samples on Viti Levu, Fiji, with the most current available geological and topographic mapping of the respective river drainage basins to compare detrital populations with potential bedrock sources. The temporal and spatial variations in zircon geochemistry supplement what is known from igneous rocks and...

Passive acoustic monitoring and convolutional neural networks facilitate high-resolution and broadscale monitoring of a threatened species Passive acoustic monitoring and convolutional neural networks facilitate high-resolution and broadscale monitoring of a threatened species
Population monitoring is an essential component of biodiversity conservation and management, but low detection probabilities for rare and/or cryptic species makes estimating abundance and occupancy challenging. Passive acoustic monitoring combined with machine learning algorithms represents a potential path forward to effectively and efficiently monitor the occurrence of rare vocalizing...

The evolution of a young ocean within Mimas The evolution of a young ocean within Mimas
The fractured, young surfaces on confirmed ocean worlds such as Europa and Enceladus suggest that ocean-bearing moons with relatively thin overlying ice shells should be easy to identify. Hence, the discovery that Mimas’ rotation state is best explained by an internal ocean seems challenging to reconcile with its heavily cratered surface. Previous studies have shown that an internal...

Bringing traits back in the equation: A roadmap to understand species redistribution Bringing traits back in the equation: A roadmap to understand species redistribution
Ecological and evolutionary theories have proposed that species traits should be important in mediating species responses to contemporary climate change; yet, empirical evidence has so far provided mixed evidence for the role of behavioral, life history, or ecological characteristics in facilitating or hindering species range shifts. As such, the utility of trait-based approaches to...

National shoreline change—Summary statistics for vector shorelines from the early 1900s to the 2010s for Puerto Rico National shoreline change—Summary statistics for vector shorelines from the early 1900s to the 2010s for Puerto Rico
The U.S. Geological Survey (USGS) maintains a database of historical shoreline positions for the United States coasts derived from historical sources, such as aerial photographs or topographic surveys, and contemporary sources, such as modern orthophotography, light detection and ranging (lidar) point clouds, and digital elevation models. These shorelines are compiled within a geographic

Using ground crack and very low frequency measurements to map the location of the June 2007 Father’s Day dike, Kīlauea Volcano Using ground crack and very low frequency measurements to map the location of the June 2007 Father’s Day dike, Kīlauea Volcano
An intrusion into Kīlauea’s upper East Rift Zone during June 17–19, 2007, during the 1983–2018 Pu‘u‘ō‘ō eruption, led to widespread ground cracking and a small (approximately 1,525 cubic meters) eruption on the northeast flank of Kānenuiohamo, a cone about 6 kilometers upslope from Pu‘u‘ō‘ō. Transmitted and induced very low frequency (VLF) magnetic fields were measured with a handheld...

Seasonal and species-level water-use strategies and groundwater dependence in dryland riparian woodlands during extreme drought Seasonal and species-level water-use strategies and groundwater dependence in dryland riparian woodlands during extreme drought
Drought-induced groundwater decline and warming associated with climate change are primary threats to dryland riparian woodlands. We used the extreme 2012–2019 drought in southern California as a natural experiment to assess how differences in water-use strategies and groundwater dependence may influence the drought susceptibility of dryland riparian tree species with overlapping...

Management implications of habitat selection by whooping cranes (Grus americana) on the Texas coast Management implications of habitat selection by whooping cranes (Grus americana) on the Texas coast
Effective habitat management for rare and endangered species requires a thorough understanding of their specific habitat requirements. Although machine learning models have been increasingly used in the analyses of habitat use by wildlife, the primary focus of these models has been on generating spatial predictions. In this study, we used machine learning models in combination with...

Paranannizziopsis spp. Infection in Wild Vipers, Europe Paranannizziopsis spp. Infection in Wild Vipers, Europe
We describe the first detection of Paranannizziopsis sp. in a wild population of vipers in Europe. Fungal infections were severe and one individual likely died from infection. Surveillance efforts are needed to better understand the threat of this pathogen to snake conservation.

Forecasting the long-term spatial distribution of earthquakes for the 2023 US National Seismic Hazard Model using gridded seismicity Forecasting the long-term spatial distribution of earthquakes for the 2023 US National Seismic Hazard Model using gridded seismicity
Probabilistic seismic hazard analyses such as the U.S. National Seismic Hazard Model (NSHM) typically rely on declustering and spatially smoothing an earthquake catalog to estimate a long‐term time‐independent (background) seismicity rate to forecast future seismicity. In support of the U.S. Geological Survey’s (USGS) 2023 update to the NSHM, we update the methods used to develop this...

Hotspots of biogeochemical activity linked to aridity and plant traits across global drylands Hotspots of biogeochemical activity linked to aridity and plant traits across global drylands
Perennial plants create productive and biodiverse hotspots, known as fertile islands, beneath their canopies. These hotspots largely determine the structure and functioning of drylands worldwide. Despite their ubiquity, the factors controlling fertile islands under conditions of contrasting grazing by livestock, the most prevalent land use in drylands, remain virtually unknown. Here we...
