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...
A novel expert-driven methodology to develop thermal response curves and projec...
Sousa, Andreia G.; Fernandez, Marc; Alves, Filipe M. A.; Arranz, Patricia; Dinis, Ana; González García, Laura; Morales, Misael; Lettrich, Matthew D.Over the last decades, global warming has contributed to changes in marine species composition, abundance and distribution, in response to changes in oceanographic conditions such as temperature, acidification, and deoxygenation. Experimentally derived thermal limits, which are known to be related to observed latitudinal ranges, have been used to assess variations in species distribution patterns. However, such...
Gymnodinium catenatum paralytic Shellfish toxin production and photobiological ...
Lopes, Vanessa M.; Court, Mélanie; Seco, Martim Costa; Borges, Francisco O.; Vicente, Bernardo; Lage, Sandra; Braga, Ana Catarina; Duarte, BernardoMarine heatwaves (MHWs) have doubled in frequency since the 1980s and are projected to be exacerbated during this century. MHWs have been shown to trigger harmful algal blooms (HABs), with severe consequences to marine life and human populations. Within this context, this study aims to understand, for the first time, how MHWs impact key biological and toxicological parameters of the paralytic shellfish toxin (P...
Impacts of climate change on the biogeography of three amnesic shellfish toxin ...
Borges, Francisco O.; Lopes, Vanessa M.; Santos, Catarina Frazão; Reis Costa, Pedro; Rosa, RuiHarmful algal blooms (HABs) are considered one of the main risks for marine ecosystems and human health worldwide. Climate change is projected to induce significant changes in species geographic distribution, and, in this sense, it is paramount to accurately predict how it will affect toxin-producing microalgae. In this context, the present study was intended to project the potential biogeographical changes in ...
