Rays of the family Rhinopteridae Jordan & Evermann, 1896 are highly migratory and widely distributed in warm tropical and temperate waters. Along the Brazilian coast, the presence of two species has been recorded: Rhinoptera bonasus Mitchill, 1815 and Rhinoptera brasiliensis Müller, 1836. These stingrays are commonly caught as bycatch in trawl fisheries, however, the two species lack distinctive external morphological features...

The relative importance of environmental selection, dispersal, and demographic stochasticity in structuring aquatic communities remains poorly resolved, especially in human-impacted Neotropical regions. Using diatoms, we assessed how local environmental conditions, catchment land use, and spatial factors shape community richness and composition in subtropical streams, and whether responses differ among common, rare, and very r...

Rare Earth Metals (REMs) are vital for advanced technologies, yet they face increasing supply risks, emphasising the need for efficient recovery from secondary resources such as NdFeB magnet waste. The present work details the development and characterisation of magnetically responsive vermiculite-based nanocomposites, with and without alginate immobilisation, aimed at the selective recovery of neodymium (Nd(III)) and dysprosi...

Bees are essential for ecosystem functioning, pollinating many wild and crop plant species. Predicting which species are most vulnerable to global changes, and how their loss may impact ecosystems and human well-being, is critical. Comprehensive information on bee response and effect traits is fundamental to these assessments. However, the Raunkiærian shortfall—insufficient trait data—remains significant for bees, particularly...

Climate change is a growing threat that requires collective action to alter the technologies, consumption, and production methods. Circular economy aims to enhance resource efficiency and reduce waste, but its synergies and antagonists with climate mitigation and innovative policy approaches remain unknown. This study illustrates the antagonisms and synergy paths between climate mitigation and circular practices via a systemat...

Endothelial cells (ECs) are arranged side-by-side to create a semi-permeable monolayer, forming the inner lining of every blood vessel (micro and macrocirculation). Serving as the first barrier for circulating molecules and cells, ECs represent the main regulators of vascular homeostasis being able to respond to environmental changes, either physical or chemical signals, by producing several factors that regulate vascular tone...
