Risk of falls and syncope across frailty levels in hypertensive older adults: a longitudinal studyNARA Subscribed
In older hypertensive adults, frailty may increase the risk of adverse events associated with blood pressure lowering, including syncope and falls. However, the degree of frailty at which these risks become clinically significant remains uncertain. The study aimed to compare clinical characteristics and the incidence of falls and syncope across different frailty levels among older hypertensive adults. We analyzed data from the...
Increased CH 4 Oxidation in Arctic Tundra Ecosystems Caused by Vegetation‐Mediated Soil DryingNARA Subscribed
Arctic tundra soils can act as an important sink for atmospheric methane (CH 4 ). However, the role and magnitude of this process, and how it will change during future climate scenarios, are poorly understood. The vegetation is changing with a warmer Arctic climate, with taller plants, more shrubs, and altered vegetation patterns. These changes are predicted to be strongest in moist to wet regions, areas usually associated wit...
The performance of the European Consortium Earth-system model (EC-EARTH) in the boreal winter stratosphere is comprehensively assessed for the first time, in particular its version 3.3 that contributes to CMIP6. A 100-year long simulation with prescribed climatological boundary conditions and fixed radiative forcing, representative of present-day climate, is used to evaluate the simulation of the climatological stratospheric c...
Reduced methane emissions in former permafrost soils driven by vegetation and microbial changes following drainageNARA Subscribed
In Arctic regions, thawing permafrost soils are projected to release 50 to 250 Gt of carbon by 2100. This data is mostly derived from carbon‐rich wetlands, although 71% of this carbon pool is stored in faster‐thawing mineral soils, where ecosystems close to the outer boundaries of permafrost regions are especially vulnerable. Although extensive data exists from currently thawing sites and short‐term thawing experiments, invest...
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...
Immediate and carry‐over effects of insect outbreaks on vegetation growth in West Greenland assessed from cells to satelliteNARA Subscribed
Aim Tundra ecosystems are highly vulnerable to climate change, and climate–growth responses of Arctic shrubs are variable and altered by microsite environmental conditions and biotic factors. With warming and drought during the growing season, insect‐driven defoliation is expected to increase in frequency and severity with potential broad‐scale impacts on tundra ecosystem functioning. Here we provide the first broad‐scale reco...
Seasonal patterns in the abundance of E ctopleura crocea ( C nidaria: H ydrozoa) on a shipwreck in the N orthern A driaticNARA Subscribed
Ectopleura crocea is an A nthomedusan hydroid, frequently recorded and abundant on artificial substrates. Here we examine whether the abundance of this species varies seasonally on a shipwreck in the N orthern A driatic at a depth of 10–12 m. Individuals were first found in late autumn when temperatures had dropped below 15 °C, forming scattered colonies composed of a few, small hydranths bearing immature gonophores. Substratu...
