- Occurrences of pinnipeds (Carnivora, Phocidae) in the Azores archipelago (Portugal)Publication . Barcelos, Luis M. D.; Barreiros, João P.An inventory of historical and actual occurrences of pinnipeds in the Azores archipelago. The data used come from Silva et al. (2009) and from RACA - Rede de Arrojamentos de Cetáceos dos Açores (RACA-DRAM-RAA).
- Pinniped (Carnivora, Phocidae) occurrences in the Azores Archipelago (NE Atlantic)Publication . Barcelos, Luis M. D.; Barreiros, João P.BACKGROUND: The last Pinniped species update was in 2010, as part of the list of the terrestrial and marine biota from the Azores. This list includes a chapter dedicated to marine mammals, based on previously published bibliography. NEW INFORMATION: No new species were added since that list was published. However, there were new occurrences since the last update.
- Updated checklist of Azores Chondrichthyes (Vertebrata: Gnathostomata)Publication . Barcelos, Luis M. D.; Azevedo, José M. N.; Barreiros, João P.Chondrichthyes are commonly known as cartilaginous fishes and includes chimeras, sharks and rays. They can be found from the cold deep-sea to subtropical and tropical waters (Greemberg 2009). Sharks and rays have a great recreational and ecological interest (Vieira et al. 2020); however, many species worldwide are declining due to global overfishing (Worm et al. 2013). The total estimation for risk extinction, according to the IUCN Red List criteria, indicates that a quarter of all shark and ray species are threatened (Dulvy et al. 2014). The first comprehensive chondrichthyan checklist for Azores was published over 20 years ago by Santos et al. (1997). After that, some updates were made, most of them integrated in marine fish or biodiversity lists (e.g. Porteiro et al. 2010). In the meantime, new publications have emerged regarding new records (e.g. Catarino et al. 2020) or with new information on species already recorded for Azores (e.g. Das and Afonso 2017, Barcelos et al. 2018). The present work gives taxonomic updates and information regarding the conservation status (IUCN) for all chondrichthyan species from the Azores' EEZ. This is the first complete and updated list of chondrichthyans that can be found in the GBIF online platform (Barcelos et al. 2020).
- Updated checklist of Azores Actinopterygii (Gnathostomata: Osteichthyes)Publication . Barcelos, Luis M. D.; Azevedo, José M. N.; Barreiros, João P.BACKGROUND Since the first published comprehensive checklist of Azorean fishes - covering the whole Exclusive Economic Zone (EEZ) region - several new records have been published and an updated checklist published in 2010. This new dataset covers all confirmed species of actinopterygians for the Azorean EEZ. NEW INFORMATION In this update, we made corrections to the previous checklists, updated the taxonomy according to the most recent bibliography and added two new species to the Azorean Actinopterygii checklist.
- Sea turtle (Reptilia, Testudines) diversity and occurrence in the Azores Archipelago (NE Atlantic)Publication . 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 reports has been verified as expected. The leather back turtle, Dermochelys coriacea (Vandelli, 1761) is the second most observed species in the Azores' EEZ, a fact probably also linked to the tuna fishery observation programme. All other species are occasional/vagrant albeit the green turtle, Chelonia mydas (Linnaeus, 1758) is more commonly seen than the others. Historically, sea turtles were occasionally taken for food in specific fishing villages and ports. Since 1986, sea turtles, as well as all marine mammals, are fully protected in the Azores although human-related activities (e.g. plastics, discarded fishing gear) do generate serious injuries and deaths. NEW INFORMATION: In this paper, we update sea turtle species' checklist for the Azores and give detailed geographic coordinates on their known occurrences.
- Phocidae species in Azores archipelagoPublication . Barcelos, Luis M. D.; Barreiros, João P.List of Phocidae species recorded in Azores archipelago (Portugal).
- Cetáceos…esses desconhecidosPublication . Barcelos, Luis M. D.Cetáceos, do grego (ketos: monstro marinho) e do latim (cetos: grande animal marinho), designa um grupo de mamíferos marinhos, popularmente conhecidos como baleias e golfinhos. Animais carismáticos, sejam os pequenos e ágeis golfinhos ou as grandes e majestodas baleias, geraram fascínio, admiração e medo, mas também foram fonte de riqueza e meio de subsistência para diversos povos em todo o mundo. São na sua maioria espécies cosmopolitas, ocorrendo de polo a polo nos oceanos, havendo, no entanto, algumas que, devido à sua ecologia e status populacionais, são restritas a pequenas faixas de alguns milhares de quilómetros quadrados ou menos.
- First record of the Olive Ridley Sea Turtle, Lepidochelys olivacea (Eschscholtz, 1829), in the Azores Islands, northeastern Atlantic Ocean (Testudines, Cheloniidae)Publication . Barcelos, Luis M. D.; Michielsen, Gerbrand; Sérgio, Bruno; Oliveira, Suzi; Barreiros, João P.While on their way northwestwards to D. João de Castro Bank in the Portuguese Azores Islands for diving and birdwatching on 9 October 2020, occupants of a rib boat from the Best Spot Azores Dive Center (São Miguel Island, Azores), spotted a sea turtle with a bird on top of its carapace, at a position halfway between Ponta dos Mosteiros on São Miguel Island and the bank (37.9676°N, 26.1671°W; Fig. 1). The bird was identified as a Common Tern (Sterna hirundo Linnaeus, 1758) and photos were taken. […].
- A healed propeller wound on a wild loggerhead turtle, Caretta caretta (Testudines, Cheloniidae), occupied by a pelagic crab, Planes minutus, in the Azores Islands, PortugalPublication . Anjos, Marcelo R.; Pelegrini, Larissa S.; Barreiros, João B. V.; Barcelos, Luis M. D.; Barreiros, João P.This paper details and discusses a helix-induced injury to the right anterior shell of a seemingly healthy subadult loggerhead turtle. On 10 September 2018, two of the authors (JBB and JPB) located a loggerhead sea turtle resting on the rocky reef bottom at a depth of about 10 m while freediving off the southeastern coast of Terceira Island, Azores [...]
- First record of the White-winged Scoter, Melanitta deglandi (Bonaparte, 1850) (Anseriformes: Anatidae) for the Azores and PortugalPublication . Barcelos, Luis M. D.; Coelho, Rúben; Coelho, Elizabeth; Ázera, Susana; Barreiros, João P.In this study, we report the frst occurrence of the White-winged Scoter Melanitta deglandi for the Azores archipelago and for Portugal. This report is based on a single individual observed in Angra do Heroísmo Bay on 08 December 2020. The record has been approved by the Portuguese Rarities Committee and described as a frst winter female. The occurrence of Nearctic birds in the Azores is important due to the geographic location of the archipelago and its relevance as a stepping stone for migratory species.
