The genus Amblyomma koch, 1844 contains approximately 138 species, which are mainly distributed in the Afrotropical, Oriental, Neotropical and Australasian zoogeographic regions. This is an important group of arthropod vectors responsible for transmitting a wide range of etiological agents that cause infections and diseases in humans and animals, and is therefore of great interest to public and veterinary health.This study des...

The seafloor is recognized as a major sink for marine debris, while deep-sea litter remains poorly investigated due to the logistical and economic constraints associated with seabed exploration. This study reports for the first time the occurrence of marine debris found on the Argentine deep seafloor using the SOI’s Remotely Operated Vehicle (ROV), providing the first documented evidence for this region. A total of 29 litter i...

Humpback whales ( Megaptera novaeangliae ) from breeding stock A migrate annually between Antarctic feeding grounds (~65° S) and Brazilian breeding areas (~17° S). Traditionally considered to fast during migration, recent feeding observations and increased strandings along southeastern Brazil (~23° S) raise questions about possible shifts in foraging behavior. We hypothesize that some individuals are modifying their feeding st...

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...

Kelp forests are among the most extensive and productive coastal ecosystems, yet they remain underrepresented in global conservation policy despite widespread declines driven by interacting global- (i.e., ocean warming, marine heatwaves) to local-scale stressors. At the same time, kelp conservation and restoration efforts are expanding rapidly across regions, but measures of success and syntheses tend to primarily focus on eco...

Aims The incorporation of Plant Growth-Promoting Bacteria (PGPB) into compost is a promising strategy to enhance the potential of organic fertilizers. This study investigates in a pot experiment the potential of hydrogel capsules containing a PGPB consortium to improve compost efficiency, promote crop growth, and increase nutrient uptake. Methods Three PGPB strains ( Rhizobium leguminosarum T88, Herbaspirillum frisingense AP21...

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...
