Actinostella flosculifera (Le Sueur, 1817) is a common species of sea anemone in the tropical Atlantic’s coastal and reef ecosystems, with records ranging from Bermuda Islands to Brazil, and from some areas of the Eastern Atlantic. Actinostella flosculifera exhibits wide morphological variability, mainly in terms of coloration patterns and a range of different sizes. We conducted a morphological and genetic study of this speci...
Impact of open-air dumping of urban solid waste on soil toxicity and properties in a tropical environmentNARA Subscribed
Open dumping (OD) is uncontrolled dumping of solid waste (SW) in an environment. It involves the illegal practice of dumping waste in areas not designated for waste management, such as open lands, flowing water bodies, or exposed waste piles. OD can contain a complex mixture of organic fractions, and various contaminants that, when infiltrated into the soil through leachate, compromise its stability and resistance. These conta...
Human‐induced high densities of large wild herbivores may pose a threat to natural ecosystems, modifying biodiversity and ecosystem functioning. Although the negative impacts on individual taxa and processes are well documented, a comprehensive understanding of how ecosystem integrity responds to high herbivore densities remains limited. This study addresses this gap through an extensive herbivore‐density manipulation experime...
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...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Chronosequences provide space-for-time substitutions to study ecological succession and guide restoration efforts. We evaluated seed rain dynamics across a tropical forest chronosequence in the lowland mountain landscape of Caquetá, Colombia, using monthly seed trap data collected from September 2017 to August 2018 in 18 plots (50 × 50 m) classified into early-secondary, intermediate-secondary, and old-growth forest. Seed morp...
Fossilised plant resin (amber) collections represent invaluable sources of information about the past. However, amber is particularly sensitive to exposure to light and oxygen, as well as changing temperature and humidity, rendering its preservation a major challenge. Here we reveal significant degradation of raw and carved amber specimens from part of the Early Cretaceous amber collection of Rábago-El Soplao (Cantabria, Spain...
