Coastal waters are increasingly susceptible to low-oxygen conditions where circulation or nutrient inputs have been altered by anthropogenic activities, leading to increased occurrence of coastal hypoxia worldwide. Low-oxygen conditions also occur naturally in coastal settings, typically in bottom water or landward of sills where circulation is weak. Here we identify and characterize a persistent, low-oxygen layer in the mid-w...
Drivers of Extreme Carbon Sources and Sinks Across Diverse Ecosystems in the Western USANARA Subscribed
Increasing climate variability is impacting the carbon cycle in unprecedented ways, demanding an understanding of the conditions leading to extreme carbon flux states. In this study, we sought to determine the strength and influential timescales of key environmental drivers governing unusually high daily gross primary productivity (GPP) and ecosystem respiration (R eco ) across diverse ecosystems in the western USA. We obtaine...
The 2022 eruption of Mauna Loa, Hawaiʻi: a synoptic and retrospective overview of the eruptionNARA Subscribed
Mauna Loa volcano erupted on November 27, 2022, after 38 years of quiescence, marking the first eruption of the world’s largest active volcano since 1984. Precursory activity was characterized by escalating seismicity and ground deformation, with increased unrest beginning in mid-September 2022. At 22:24 HST, tilt and seismic alarms alerted Hawaiian Volcano Observatory staff to escalating activity, signaling an imminent erupti...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Views and experiences regarding workplace genetic testing: findings from a national survey of U.S. employeesNARA Subscribed
The emergence of voluntary health-related genetic testing in workplace wellness programs indicates a need to understand employees’ views and experiences regarding workplace genetic testing (wGT). A large, diverse national sample of employed adults ( N =2000; median age=43 years; 51.1% female; 33% non-white) completed a web survey of their wGT views and experiences. Although 80% of participants indicated their employer did not...
Recombination Rate and Recurrent Linked Selection Shape Correlated Genomic Landscapes Across a Continuum of Divergence in SwallowsNARA Subscribed
Disentangling the drivers of genomic divergence during speciation is essential to our broader understanding of the generation of biological diversity. Genetic changes accumulate at variable rates across the genome as populations diverge, leading to heterogenous landscapes of genetic differentiation. The ‘islands of differentiation’ that characterise these landscapes harbour genetic signatures of the evolutionary processes that...
Eelgrass ( Zostera marina ) creates valuable, biodiverse habitats worldwide, but is at risk from combined environmental stressors and disease. We surveyed paired intertidal and subtidal meadows for seagrass wasting disease in the San Juan Islands, WA, USA in summers 2017–2019 to determine how disease varied with depth, temperature, and salinity. We expected reduced disease in deeper meadows with more stable environmental condi...
