Longest documented coastal migrations of shortnose sturgeonNARA Subscribed
The shortnose sturgeon (SNS; Acipenser brevirostrum ) is a United States federally endangered diadromous species. Although SNS spend much of their time in riverine habitat, inter‐river migrations have been documented in northern populations. However, the inter‐river migratory behaviour and distance capabilities of southern SNS are poorly understood. In this communication, we describe two SNS that migrated approximately 425 km...
Active touch in tactile perceptual discrimination: brain activity and behavioral responses to surface differencesNARA Subscribed
This study investigates the neural and behavioral mechanisms of tactile perceptual discrimination using fMRI and a set of wrinkled surface stimuli with varying textures. Fifteen female participants were tasked with distinguishing between different surfaces by touch alone. Behavioral results demonstrated variable discriminability across conditions, reflecting the tactile sensitivity of human fingertips. Neural analysis showed v...
SNAPSHOT USA 2019–2023: The First Five Years of Data From a Coordinated Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multicontributor 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 specie...
Heritable differences in abundance of bacterial rhizosphere taxa are correlated with fungal necrotrophic pathogen resistanceNARA Subscribed
Host–microbe interactions are increasingly recognized as important drivers of organismal health, growth, longevity and community‐scale ecological processes. However, less is known about how genetic variation affects hosts' associated microbiomes and downstream phenotypes. We demonstrate that sunflower ( Helianthus annuus ) harbours substantial, heritable variation in microbial communities under field conditions. We show that m...
Global maps of soil temperatureNARA Subscribed
Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and bioclimatic variables at a 1‐km 2 r...
Common, low-frequency, rare, and ultra-rare coding variants contribute to COVID-19 severityNARA Subscribed
The combined impact of common and rare exonic variants in COVID-19 host genetics is currently insufficiently understood. Here, common and rare variants from whole-exome sequencing data of about 4000 SARS-CoV-2-positive individuals were used to define an interpretable machine-learning model for predicting COVID-19 severity. First, variants were converted into separate sets of Boolean features, depending on the absence or the pr...
The finishing touches: the role of friction and roughness in haptic perception of surface coatingsNARA Subscribed
Humans are extraordinarily skilled in the tactile evaluation of, and differentiation between, surfaces. The chemical and mechanical properties of these surfaces are translated into tactile signals during haptic exploration by mechanoreceptors in our skin, which are specialized to respond to different types of temporal and mechanical stimulation. Describing the effects of measurable physical characteristics on the human respons...
Effect of single dose N-acetylcysteine administration on resting state functional connectivity in schizophreniaNARA Subscribed
Rationale There is interest in employing N-acetylcysteine (NAC) in the treatment of schizophrenia, but investigations of the functional signatures of its pharmacological action are scarce. Objectives The aim of this study was to identify the changes in resting-state functional connectivity (rs-FC) that occur following administration of a single dose of NAC in patients with schizophrenia. A secondary aim was to examine whether...
