This study describes the first potential multi-species shark nursery area in Atlantic Africa (Sal Rei Bay – SRB, Boa Vista Island, Cabo Verde). From August 2016 to September 2019, 6162 neonates and juveniles of 5 different shark species were observed in SRB using beach gillnet-based bycatch survey...

Rui Rosa has been nominated Speciality Chief Editor na Frontiers in Marine Science – section Marine Biology.

Marine biology covers the life of organisms, including bacteria, plants and animals, found in the sea. Marine organisms are found on the surface of the water right through to the deepest depths of the oceans. The habitats in which they are found are vast including rocky and coral reefs, seamounts an...

New cephalopod-related paper out

Coastal marine ecosystems are currently being exposed to climate change at a much faster rate than many other ecosystems, with coastal species being exposed to multiple stressors. Cephalopod mollusks play a pivotal role in marine trophic webs, and most are “keystone” species due to their influen...

Abstract submission deadline for CIAC 2022 was extended - October 31!!

The “Anthropocene” has been announced as a new geological era driven by humankind. Within the Anthropocene, ocean biodiversity is being threaten by stressors such as overfishing, pollution, or climate change. Keeping in mind there are winners and losers of such human-induced global changes, ther...

Despite the long evolutionary history of this group, the challenges brought by the Anthropocene have been inflicting an extensive pressure over sharks and their relatives. Overexploitation has been driving a worldwide decline in elasmobranch populations, and rapid environmental change, triggered by....

Os investigadores do MARE Marisa Vedor e Rui Rosa, em estreita colaboração com investigadores do CIBIO/InBIO - Universidade do Porto e da Universidade de Southampton, publicaram recentemente o artigo " Oceanic Diel Vertical Movement Patterns of Blue Sharks Vary With Water Temperature and Productivity to Change Vulnerability to Fishing” na revista Frontiers in Marine Sciences. O estudo demonstra que os tubarões azuís estão mais vulneráveis à pesca durante os períodos de lua cheia e em zonas epipelágicas com maior produtividade.

O artigo está disponível em https://doi.org/10.3389/fmars.2021.688076.

In the pelagic environment diel vertical movements (DVM) are widespread across taxa, from zooplankton ascending from day-time depths into surface layers at night to avoid visual predators, to apex predators following prey movements to maximise foraging opportunities. The drivers of DVM in large pred...
