Global assessment of marine plastic exposure risk for oceanic birds
Clark, Bethany L.; Carneiro, Ana P. B.; Pearmain, Elizabeth J.; Rouyer, Marie-Morgane; Clay, Thomas A.; Cowger, Win; Phillips, Richard A.Plastic pollution is distributed patchily around the world’s oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters plastic is crucial for targeting research and mitigation. Oceanic seabirds, particularly petrels, frequently ingest plastic, are highly threatened, and cover vast distances during foraging and m...
Multispecies tracking reveals a major seabird hotspot in the North Atlantic
Davies, Tammy E.; Carneiro, Ana P.B.; Tarzia, Marguerite; Wakefield, Ewan; Hennicke, Janos C.; Frederiksen, Morten; Hansen, Erpur Snær; Campos, BrunaThe conservation of migratory marine species, including pelagic seabirds, is challenging because their movements span vast distances frequently beyond national jurisdictions. Here, we aim to identify important aggregations of seabirds in the North Atlantic to inform ongoing regional conservation efforts. Using tracking, phenology, and population data, we mapped the abundance and diversity of 21 seabird species....

The distribution of Mola alexandrini in the Subtropical Eastern Atlantic, with ...
Wirtz, Peter; Biscoito, Manuelhe presence of the “Bump-head sunfish” Mola alexandrini (Ranzani 1839) is recorded, via photographic evidence, from the Azores, Madeira Island, the Canary Islands, and the Cape Verde Islands. Eastern Atlantic individuals of Mola mola can also have a bump on the head.; FCT: UID/MAR/04292/2019; Project M1420-01-0145-FEDER-000001.
Global spatial ecology of three closely-related gadfly petrels
Ramos, Raül; Ramírez, Iván; Paiva, Vitor H.; Militão, Teresa; Biscoito, Manuel; Menezes, Dília; Phillips, Richard A.; Zino, FrancisThe conservation status and taxonomy of the three gadfly petrels that breed in Macaronesia is still discussed partly due to the scarce information on their spatial ecology. Using geolocator and capture-mark-recapture data, we examined phenology, natal philopatry and breeding-site fidelity, year-round distribution, habitat usage and at-sea activity of the three closely-related gadfly petrels that breed in Macaro...
Larval cestodes infecting the deep-water fish, Cataetyx laticeps (Pisces: Bythi...
Costa, Graça; Khadem, Mahnaz; Dellinger, Thomas; Biscoito, Manuel; Moreira, Egberto MeloParasites of deep-water fishes are less known in comparison to the parasites of fishes living in the demersal and epipelagic ocean zones. In the present research note we report the occurrence of larval trypanorhynch cestodes in a rare deep-water fish, the deep-water brotula, Cataetyx laticeps. Based on the 28S rDNA (region D1-D3) sequence homology and the phylogenetic analysis, the larval cestodes are putativel...
Ichthyofauna of the Selvagens Islands. Do small coastal areas show high species...
Almada, Frederico; Abecasis, David; Villegas-Ríos, David; Henriques, Sofia; Pais, Miguel Pessanha; Batista, Marisa Isabel; Costa, Bárbara Horta eThe Selvagens Islands are located in the northeastern Atlantic between the Canary Islands and Madeira Island. As a result of their small size, remote location and harsh sea conditions only a few studies have been conducted to describe their marine species diversity. We were able to identify 29 new coastal fish species, an increase of 33% in the ichthyofauna described for these islands (n = 88). There is a preva...
Leapfrog migration and habitat preferences of a small oceanic seabird, Bulwer's...
Ramos, Raül; Sanz, Víctor; Militão, Teresa; Bried, Joël; Neves, Verónica C.; Biscoito, Manuel; Phillips, Richard A.; Zino, FrancisAIM: Our current understanding of migratory strategies and the reasons for their high variability along the phylogenetic tree remains relatively poor. Most of the hypotheses relating to migration have been formulated for terrestrial taxa; classically, oceanic migrations were considered as merely dispersive because of the scarcity of observations in the open ocean. We describe for the first time, the migration s...
Considerations on the biology of Plesionika narval (Fabricius, 1787) in the Nor...
Sousa, Ricardo; Henriques, Paulo; Biscoito, Manuel; Pinto, Ana Rita; Delgado, João; Dellinger, Thomas; Pinho, Mário RuiLife history traits of Plesionika narval were studied in the Northeastern Atlantic, Madeira archipelago including growth, age, sexual maturity, recruitment pattern and mortality. A total of 28,262 specimens were sampled over a period of 8 years comprising two time series from 1991 to 1995 and 2004 to 2008. The relative growth pattern showed a negative allometric nature of growth for combined sexes, males, femal...
