Shoreline change of western Long Island, New York, from satellite-derived shorelines Shoreline change of western Long Island, New York, from satellite-derived shorelines
Shoreline measurement techniques using satellite-derived imagery can provide decades of observations of shoreline change. Here we apply these techniques to the western south shore of Long Island, New York, which has three distinct beaches, Rockaway Peninsula, Long Beach, and Jones Beach Island, which are 18, 15, and 24 km in length, respectively. These beaches are recreation areas for...

Advancing the science of headwater streamflow for global water protection Advancing the science of headwater streamflow for global water protection
The protection of headwater streams faces increasing challenges, exemplified by limited global recognition of headwater contributions to watershed resiliency and a recent US Supreme Court decision limiting federal safeguards. Despite accounting for ~77% of global river networks, the lack of adequate headwaters protections is caused, in part, by limited information on their extent and...

Fish-assemblage evaluation in the lower Sandusky River, Ohio, following dam removal Fish-assemblage evaluation in the lower Sandusky River, Ohio, following dam removal
The Sandusky River, Ohio, USA, has experienced more than a century of alterations, including dam implementation and removal, causing a cascade of habitat changes. The physical changes in the river led to establishment of several invasive species. Ten hoop-net sampling sites, spaced about 500 m apart were established in the river to monitor fish assemblage and their habitat preferences...

The progression of basaltic–rhyolitic melt storage at Yellowstone Caldera The progression of basaltic–rhyolitic melt storage at Yellowstone Caldera
Yellowstone Caldera is one of the largest volcanic systems on Earth, hosting three major caldera-forming eruptions in the past two million years, interspersed with periods of less explosive, smaller-volume eruptions1. Caldera-forming eruptions at Yellowstone are sourced by rhyolitic melts stored within the mid- to upper crust. Seismic tomography studies have suggested that a broad region...

Sex differences in migration routes and non-breeding areas of a declining shorebird Sex differences in migration routes and non-breeding areas of a declining shorebird
Migratory birds face different threats and pressures across their annual cycle, and understanding the impact of these factors on individuals is critical to the conservation of avian populations. Individuals from the same breeding population may share the same non-breeding areas, and thus experience similar conditions, or they may travel to different habitats or regions during migration...

Evaluating effects of tracking device attachment methods on Black Oystercatchers Haematopus bachmani Evaluating effects of tracking device attachment methods on Black Oystercatchers Haematopus bachmani
Advances in tracking technology are greatly improving our understanding of many aspects of avian ecology. However, the diversity of tracking devices and attachment methods necessitates better evaluation of how they affect particular taxa. We evaluated effects of tracking devices mounted on leg bands or attached using leg-loop harnesses on resighting rates of Black Oystercatchers...

Public, bottled, and private drinking water: Shared contaminant-mixture exposures and effects challenge Public, bottled, and private drinking water: Shared contaminant-mixture exposures and effects challenge
BACKGROUND: Humans are primary drivers of environmental contaminant exposures worldwide, including in drinking-water (DW). In the United States (US), point-of-use DW (POU DW) is supplied via private tapwater (TW, predominantly private wells), public-supply TW, and bottled water (BW). Differences in management, monitoring, and messaging and lack of directly intercomparable exposure data...

3D Dynamic rupture modeling of the 6 February 2023, Kahramanmaraş, Turkey Mw 7.8 and 7.7 earthquake doublet using early observations 3D Dynamic rupture modeling of the 6 February 2023, Kahramanmaraş, Turkey Mw 7.8 and 7.7 earthquake doublet using early observations
The 2023 Turkey earthquake sequence involved unexpected ruptures across numerous fault segments. We present 3D dynamic rupture simulations to illuminate the complex dynamics of the earthquake doublet. Our models are constrained by observations available within days of the sequence and deliver timely, mechanically consistent explanations of the unforeseen rupture paths, diverse rupture...

A new genomic resource to enable standardized surveys of SNPs across the native range of brook trout (Salvelinus fontinalis) A new genomic resource to enable standardized surveys of SNPs across the native range of brook trout (Salvelinus fontinalis)
Understanding how genetic diversity is distributed across spatiotemporal scales in species of conservation or management concern is critical for identifying large-scale mechanisms affecting local conservation status and implementing large-scale biodiversity monitoring programmes. However, cross-scale surveys of genetic diversity are often impractical within single studies, and combining...

A self-determination approach to understanding leisure identity salience among lapsed hunters A self-determination approach to understanding leisure identity salience among lapsed hunters
This study extended a framework based on self-determination theory (SDT) and leisure constraints to study identity salience in lapsed hunters. Self-determination theory suggests that multiple forms of motivation influence levels of self-determination and addresses how social-contextual factors affect satisfaction of needs. Data were drawn from a survey of recently lapsed hunters in...

Accuracy and precision of U–Pb zircon geochronology at high spatial resolution (7–20 μm spots) by laser ablation-ICP-single-collector-sector-field-mass spectrometry Accuracy and precision of U–Pb zircon geochronology at high spatial resolution (7–20 μm spots) by laser ablation-ICP-single-collector-sector-field-mass spectrometry
Use of small spots (≤20µm) for laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) U-Pb zircon geochronology is of increasing interest in the Earth sciences because the temporal record of geologic processes is often preserved on a fine-scale within zircon grains. However the systematic biases and external sources of uncertainity of U-Pb ages is poorly defined when...

Assessing community assembly controls over community-scale nutrient resorption responses to nitrogen deposition Assessing community assembly controls over community-scale nutrient resorption responses to nitrogen deposition
Nutrient resorption is a fundamental physiological process in plants, with important ecological controls over numerous ecosystem functions. However, the role of community assembly in driving responses of nutrient resorption to perturbation remains largely unknown. Following the Price equation framework and the Community Assembly and Ecosystem Function framework, we quantified the...
