Preliminary deep-sea data analysis collected at Gloria seamount, Azores-Biscay ...
Tojeira, Inês; Pinto-Ribeiro, Luísa; Rafael, Teresa; Albuquerque, Mónica; Simões, Maria; Calado, António; Afonso, Andreia; Ramos, Bruno; Souto, MiguelThe present study provides the first results of the exploratory research campaign to Gloria seamount (summit at 45.03°N, 15.54°W), a newly identified seamount in the NE Atlantic. New multibeam bathymetry and an 8 h remote operated vehicle footage and photography data were compiled and analyzed to give the first insights on the geological nature and benthic megafauna assemblages of Gloria seamount. Footage evide...
Catostylus tagi (Class: Scyphozoa, Order: Discomedusae, Suborder: Rhizostomida,...
Gueroun, Sonia K.M.; Torres, Tatiana M.; Santos, Antonina dos; Vasco Rodrigues, Nuno; Canning-Clode, João; Andrade, CarlosJellyfish proliferations, which are conspicuous and natural events, cause blooms that may lead to severe consequences for anthropogenic activities and ecosystem structure and functioning. Although research during the last decade has focused on factors influencing the different jellyfish life stages, few species currently have their full life cycle known. In this context, we describe for the first time the devel...
Historical separation and present-day structure of common dolphinfish (Coryphae...
Maggio, Teresa; Allegra, Alessandro; Andaloro, Franco; Barreiros, João Pedro; Battaglia, Pietro; Butler, Christopher M; Cuttitta, AngelaThe common dolphinfish (Coryphaena hippurus) is an epipelagic, mid-trophic level, highly migratory species distributed throughout the world’s tropical and subtropical oceans in waters greater than 20C. Life-history variables, migratory behaviour, and genetic markers have been used to define major stocks in the central Atlantic Ocean and Mediterranean Sea. Here, we used the mitochondrial DNA gene NADH subunit 1 ...
Northernmost record of Hacelia attenuata (Echinodermata: Asteroidea) in the Atl...
Vasco Rodrigues, NunoBackground The seastar Hacelia attenuata is present in the Mediterranean but also in the Azores, Madeira, Canary Islands, Cape Verde and Gulf of Guinea. Methods While scuba diving in Berlengas Archipelago (Peniche, Portugal), the author observed two individuals of this species. Results This expands its geographic distributions and represents the northernmost record of this species in the Atlantic. Conclusion Ge...
Ten new records of marine fishes for São Tomé, West Africa
Vasco Rodrigues, Nuno; Fontes, Jorge; Bertoncini, Áthila AndradeThree chondrichthyes: Rhincodon typus Smith, 1828; Mobula tarapacana (Philippi, 1892); and Mobula thurstoni (Lloyd, 1908), and seven teleosts: Beryx decadactylus Cuvier, 1829; Peristedion cf. cataphractum (Linnaeus, 1758); Coryphaena hippurus Linnaeus, 1758; Liopropoma emanueli Wirtz et Schliewen, 2012; Chromis cadenati Whitley, 1951; Chromis limbata (Valenciennes, 1833); and Makaira nigricans Lacepède, 1802 we...
Herbivory drives kelp recruits into ‘hiding’ in a warm ocean climate
Franco, João N.; Wernberg, Thomas; Bertocci, Iacopo; Duarte, Pedro; Jacinto, David; Tuya, Fernando; Vasco Rodrigues, NunoAssessing effects of herbivory across broad gradients of varying ocean climate conditions and over small spatial scales is crucial for understanding its influence on primary producers. Effects of herbivory on the distribution and abundance of kelp recruits were examined experimentally at two regions under contrasting ocean climate. Specifically, the abundance and survivorship of kelp recruits and the abundance ...
