Fisher’s perceptions on shark fisheries in Sao Tome Island (Gulf of Guinea, Wes...
Pissarra, Vasco; Santana, Aristides; Panisi, Martina; Santos, Catarina Pereira; Maia, Hugulay; Vasconcelos, Lia; Nuno, Ana; Porriños, GuillermoSao Tome and Principe (STP) is a small island developing state in the Gulf of Guinea (West Africa) and is considered a global hotspot of marine biodiversity. Still, detailed information on sharks’ diversity, abundance, and respective fisheries is mainly absent. Here, we interviewed fishers from different local communities of the island of Sao Tome to characterize: i) local knowledge on shark fisheries, ii) thos...
Impact of climate change on the distribution and habitat suitability of the wor...
Guerreiro, Miguel Fernandes; Borges, Francisco Oliveira; Santos, Catarina Pereira; Xavier, José Carlos; Hoving, Henk-JanClimate change is expected to have major negative effects on marine life across phylogenetic groups. Cephalopods, however, have life history characteristics that suggest they may benefit from certain climate change scenarios. Of all cephalopods, squids reach the greatest biomasses; as a result, they are of substantial importance for human and predator consumption. To test the hypothesis that the effects of clim...
Impacts of deoxygenation and hypoxia on shark embryos anti-predator behavior an...
Varela, Jaquelino; Martins Rebocho, Sandra; Court, Melanie; Santos, Catarina Pereira; Paula, José Ricardo; Ferreira, Inês João; Diniz, MárioSimple Summary Despite their importance, sharks are among the most endangered ocean species. In addition to overexploitation and the destruction of their natural habitat, climate change is also known to pose a serious threat to them. Among the physico-chemical changes associated with climate change, oxygen loss has been the least studied in terms of its effect on shark physiology and behavior. In this study, we...
