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...
Phototactic tails: Evolution and molecular basis of a novel sensory trait in sea snakesNARA Subscribed
Dermal phototaxis has been reported in a few aquatic vertebrate lineages spanning fish, amphibians and reptiles. These taxa respond to light on the skin of their elongate hind‐bodies and tails by withdrawing under cover to avoid detection by predators. Here, we investigated tail phototaxis in sea snakes (Hydrophiinae), the only reptiles reported to exhibit this sensory behaviour. We conducted behavioural tests in 17 wild‐caugh...
Development of the Artificial WombNARA Subscribed
Evidence of paternal nutrient provisioning to embryos in broad‐nosed pipefish Syngnathus typhleNARA Subscribed
In two experiments, radioactively labelled nutrients (either 3 H‐labelled amino‐acid mixture or 14 C‐labelled glucose) were tube‐fed to brooding male Syngnathus typhle . Both nutrients were taken up by the males and radioactivity generally increased in the brood pouch tissue with time. Furthermore, a low but significant increase of 3 H‐labelled amino acids in embryos was found over the experimental interval (48 h), whereas in...
Direct and indirect effects of simulated calcareous dredge material on eggs and larvae of pink snapper Pagrus auratusNARA Subscribed
The direct and indirect effects of a simulated, calcarenite‐based dredge material on eggs and larvae of pink snapper Pagrus auratus were assessed. Direct effects were assessed by measuring hatch rate or survival of eggs and pre‐feeding larvae, respectively, over a range of concentrations and exposure durations. Exposure of eggs to suspended solid concentrations up to 10 000 mg l −1 for 24 h did not affect egg buoyancy or hatch...
The relationships between otolith score, a function of increasing stain visibility, and the ratio of alizarin complexone (mg) to fish biomass (g) for 0·1, 0·6 and 7 g black bream Acanthopagrus butcheri show that acceptable marks are produced in all size classes using a stain‐to‐biomass ratio of 3·3 mg g −1 following an immersion period of 24 h.
Skeletal myopathy in juvenile barramundi, Lates calcarifer (Bloch), cultured in potassium‐deficient saline groundwaterNARA Subscribed
Saline groundwater is being pumped from a number of locations in rural Western Australia to prevent secondary salinity impacting farmland, rural infrastructure and areas with high conservation value. Aquaculture may offset the costs of groundwater pumping, and the suitability of groundwater for finfish aquaculture is being assessed through bioassays. There are marked spatial variations in the ionic composition of saline ground...
