A glycymeris-rich unit as evidence of a late pleistocene tsunami event from NW ...
Doukani, Mohamed Amine; Satour, Linda; Ozer, Caner Kaya; Belkebir, Lahcene; Voelker, Antje; Tedjeddine, Hassane; Landau, Bernard; Uchman, AlfredCompared to the extensive research carried out on the Neogene deposits of the Lower Chelif Basin, the Pleistocene series is still poorly studied, with no detailed lithological succession published to date. This study focuses on the Glycymeris-rich Unit (GRU) along the coastal area of the Hachacha Plateau in Northwestern Algeria. This unit unconformably overlies Miocene, Pliocene, and Pleistocene basements. The ...
Palaeobiogeography of NE Atlantic archipelagos during the last Interglacial (MI...
Melo, Carlos S.; Marques da Silva, Carlos; Scarponi, Daniele; Martín-González, Esther; Rólán, Emilio; Rojas, Alejandra; Martinez, Sergio; Silva, LuísIn order to understand the complex evolutionary processes and patterns that explain current island biodiversity, large datasets and long-term analysis are required. The Last Interglacial (LIG) was one of the warmest interglacials during the last million years. How species mobility changed during this period in the Macaronesia geographical region has long intrigued scientists. It is well established that the nor...
Range expansion of tropical shallow-water marine molluscs in the NE Atlantic du...
Melo, Carlos S.; Martín-González, Esther; da Silva, Carlos M.; Galindo, Inés; González-Rodríguez, Alberto; Baptista, Lara; Rebelo, A. CristinaControlled by ecological and physical factors, marine species distribution may vary due to global climatic changes that result from range expansion or contraction (the latter caused by local disappearances, i.e., extirpations). Spanning from 13 degrees to 39 degrees N, the Macaronesian region encompasses five archipelagos located within warm-temperate to tropical climatic zones and influenced by a surface water...

Melo, Carlos S.; Martín-González, Esther; da Silva, Carlos M.; Galindo, Inés; González-Rodríguez, Alberto; Baptista, Lara; Rebelo, A. CristinaIt was with much interest that we read the comment made by Meco et al. (2022), regarding our work on “Range expansion of tropical shallow-water marine molluscs in the NE Atlantic during the last interglacial (MIS 5e): Causes, consequences and utility of ecostratigraphic indicators for the Macaronesian archipelagos”. We welcome the discussion generated by our paper and appreciate the recognition of its complexit...
Pleistocene coralline algal buildups on a mid-ocean rocky shore : Insights into...
Rebelo, Ana C.; Rasser, Michael; Ramalho, Ricardo S.; Johnson, Markes E.; Melo, Carlos S.; Uchman, Alfred; Quartau, Rui; Berning, Björn; Neto, Ana I.Located on the northern coast of Santa Maria Island (Azores Archipelago, central North Atlantic), the Lagoinhas section preserves a carbonate buildup correlated with Marine Isotope Substage (MIS) 5e, the warmest interval of the Last Interglacial. The buildup is formed mainly by crustose coralline algae (CCA) identified as Spongites sp., and some subordinate crusts of Lithophyllum sp. and Neogoniolithon sp., as ...
Diverse bioerosion structures in lower Pliocene deposits from a volcanic oceani...
Dávid, Árpád; Uchman, Alfred; Ramalho, Ricardo Dos Santos; Madeira, José; Melo, Carlos; Madeira, Patrícia; Rebelo, Ana Cristina; Berning, BjörnPliocene body fossils from Santa Maria Island, Azores, have been studied for decades, but only more recently have ichnofossils received their due attention. Calcareous Pliocene deposits from the Baía de Nossa Senhora section contain numerous, diverse, well-preserved natural casts of invertebrate borings. The study of this type of fossils adds to knowledge on the dispersal of benthic faunas across oceans to volc...
Pliocene and Late Pleistocene actinopterygian fishes from Santa Maria Island, A...
Ávila, Sérgio P.; Azevedo, José M. N.; Madeira, Patrícia; Cordeiro, Ricardo; Melo, Carlos S.; Baptista, Lara; Torres, Paulo; Johnson, Markes E.Fossil fishes are among the rarest in volcanic oceanic islands, their presence providing invaluable data for the understanding of more general (palaeo)biogeographical patterns and processes. Santa Maria Island (Azores Archipelago) is renowned for its palaeontological heritage, with representatives of several phyla, including the Chordata. We report on the fossil fishes, resulting in an increase in the number of...
Restructuring of the ‘Macaronesia’ biogeographic unit: A marine multi-taxon bio...
Freitas, Rui; M. Romeiras, Maria; Silva, Luís; Cordeiro, Ricardo; Madeira, Patrícia; González, José Antonio; Wirtz, Peter; Falcón, Jesús M.The Azores, Madeira, Selvagens, Canary Islands and Cabo Verde are commonly united under the term “Macaronesia”. This study investigates the coherency and validity of Macaronesia as a biogeographic unit using six marine groups with very different dispersal abilities: coastal fishes, echinoderms, gastropod molluscs, brachyuran decapod crustaceans, polychaete annelids, and macroalgae. We found no support for the c...
