In oligotrophic oceans, trophic transfer at the base of pelagic food webs is driven by shifts in biomass ratios of plankton microbial groups, which determine

Motorized trawling was banned off part of the Brazilian coast in 1990 due to environmental impacts, thus artisanal fishermen adopted large beach seines as an

Four new species of the scaleless black dragonfish genus Eustomias are described based on specimens collected during the ABRACOS (Acoustics along the BRAzilian COaSt) expeditions along the

Pelagic ecosystems around tropical oceanic islands are considered oases of high plankton biomass in the middleof oligotrophic “blue deserts”. To understand the dynamics of such

Phytoplankton size structure, a major determinant of trophic structure and biogeochemical functioning in pelagic ecosystems, can be described by the slope of the size-abundance spectrum

In March 2016, the passage of a cold front on the southern coast of Brazil generated extreme meteo-oceanographic conditions along the southern Brazilian coast. This

Marine mammals are considered sentinel species and may act as indicators of ocean health. Plastic residues are widely distributed in the oceans and are recognised

Mesopelagic zones (200–1,000-m depth) are characterized by relatively low light levels, cold waters, and often limited oxygen, forming a stable yet challenging habitat for their

Plastic pollution is present in most marine environments; however, contamination in pelagic predators, including species of economic interest, is still poorly understood. This study aims

Global change has a significant impact on coastal populations and their reliance on coastal ecosystems and resources. This is particularly true for small-scale fisheries (SSF)
