Sea turtle (Reptilia, Testudines) diversity and occurrence in the Azores Archip...
Barcelos, Luis M. D.; Vandeperre, Frederic; Parra, Hugo; Barreiros, João P.BACKGROUND: Six species of marine turtles occur in the Azores Archipelago. The loggerhead, Caretta caretta (Linnaeus, 1758), is by far the most common species and is being constantly monitored and tagged by a joint project between the University of the Azores and the University of Florida since 1989. With the implementation of the tuna fishery observers (for dolphin safe seals), an increment of sea turtle repor...
Effects of gear modifications in a North Atlantic pelagic longline fishery: A m...
Lima, Françoise; Parra, Hugo; Alves, Rita B.; Santos, Marco A. R.; Bjorndal, Karen; Bolten, Alan B.; Vandeperre, FredericThe threat of population declines caused by pelagic longline fisheries in the Atlantic has increased the concern to find strategies that minimize the bycatch and mortality of non-target marine animals. Gear modification, such as the use of circle hooks instead of conventional J-hooks, has been identified as an effective bycatch reduction strategy in different pelagic longline fisheries around the world. This st...
Ervilia castanea (Mollusca, Bivalvia) populations adversely affected at CO₂ see...
Martins, Marta; Silva, Marina Carreiro; Martins, Gustavo M.; Ramos, Joana B.; Viveiros, Fátima; Couto, Ruben P.; Parra, Hugo; Monteiro, JoãoSites with naturally high CO₂ conditions provide unique opportunities to forecast the vulnerability of coastal ecosystems to ocean acidification, by studying the biological responses and potential adaptations to this increased environmental variability. In this study, we investigated the bivalve Ervilia castanea in coastal sandy sediments at reference sites and at volcanic CO₂ seeps off the Azores, where the pH...
