Atmospheric forcing and ocean preconditioning for dense shelf water cascading in the northwestern MediterraneanNARA Subscribed
Dense shelf water cascading (DSWC) in the northwestern Mediterranean Sea occurs due to the densification and overflow of shelf water in winter. This process ventilates the deep basin with waters that can be denser than those generated by open-ocean convection. Between 1987 and 2021 (i.e., 35 winter periods), shelf water reached depths greater than 1000 m on only 9 occasions, and open questions remain regarding the triggering f...
The early intestinal response of Mugil cephalus to fishmeal replacement with alternative protein sources under biofloc technology (BFT) was assessed. Juvenile mullet (82.68 ± 0.05 g) were distributed among three dietary treatments with decreasing fishmeal inclusion levels of 15%, 5%, and 0%, corresponding to FM15, FM5, and FM0, respectively. After 27 days of feeding, intestinal samples were analyzed for microbiota composition,...
Soil Microbial Diversity and Network Organization Respond to Land Use and Agricultural Inputs WorldwideNARA Subscribed
Soil microbiomes are critical for ecosystem functioning, yet the global influences of climate and agricultural practices on their diversity and structure remain incompletely characterized. Here we analyzed 1921 soil samples from 33 countries worldwide across diverse biomes to assess how climate gradients and agricultural inputs, including pesticides and fertilizers, shape prokaryotic and fungal communities. We found that micro...
Key factors of the deranged antiviral response in elderly patients with COVID-19: a machine-learning analysisNARA Subscribed
Age is a well-known risk factor to develop severe viral respiratory infections, including severe COVID-19. This study aimed to identify the biological alterations linked to severe disease in elderly patients with COVID-19. For this purpose, we employed a derivation cohort with 450 SARS-CoV-2 infected and unvaccinated patients admitted to hospital wards and a validation cohort with 244 SARS-CoV-2 infected and unvaccinated patie...
Cognitive reserve (CR) and brain maintenance (BM) reflect better than expected cognition despite brain pathology and minimal age-related brain changes that explain stable cognition, respectively. Despite being commonly used, joint quantification of these concepts has been limited; our aim is to derive longitudinal CR and BM measures and investigate CR’s relationship with education and functional connectivity. We analyzed longi...
Dense shelf water cascading (DSWC) is a key oceanographic process in transferring energy and matter from continental shelves to deep ocean areas. Although intense DSWC (IDSWC) events have received most attention due to their large impacts, mild DSWC (MDSWC) events are the most frequent in the northwestern Mediterranean and are expected to become more common under climate change. However, their dynamics, particularly in the Cap...
Dense shelf water cascading (DSWC) is an oceanographic process that occurs when dense shelf water overflows over the shelf edge downslope toward the deep sea. Monitored in the northwestern Mediterranean by moorings since 1993 in the Lacaze-Duthiers Canyon and since 2005 in the Cap de Creus Canyon, numerical modeling with reanalysis extends this timeline further into the past. This study investigates a regional reanalysis (1987...
Reduced stomatal density improves water-use efficiency in grapevine under climate scenarios of decreased water availabilityNARA Subscribed
Key message The grapevine VviEPFL9 -2 paralog is specifically expressed during leaf expansion and its knockout provide a phenotype with superior adaptation to environmental stresses via reduced stomatal density. Abstract In Arabidopsis stomatal initiation relies on the transcription factor SPEECHLESS, which is positively regulated by AtEPFL9, a peptide of the epidermal patterning factor family. In grapevine, two EPFL9 paralogs...
Late 21st‐Century Climate and Land Use Driven Loss of Plant Diversity in African MountainsNARA Subscribed
With the 1.5°C–5°C increase in global temperature projected for this century, many plant species are expected to shift their distribution ranges to track their environmental requirements. Across several mountain regions, responses to climate change like upslope shifts may result in accelerated rates of species turnover, species richness increases in upper montane belts, and amplified habitat losses. Yet, evidence of how such p...
The use of eco-organic ingredients as a source of protein in aquaculture diets needs important attention due to the growing demand for organic seafood products. The present study evaluated the effects of fish meal substitution by different organic ingredients on the growth, body composition, retention efficiency, enzyme activity, and nutrient digestibility of white shrimp Penaeus vannamei. The four dietary formulations tested...
