- Additions to the marine molluscs of the Formigas Islets, Azores.Publication . Ávila, Sérgio P.; Fontes, Jorge; Tempera, Fernando; Cardigos, FredericoA fauna malacológica dos ilhéus das Formigas foi abordada por Ávila & Azevedo (1997). A presente lista vem completar e corrigir aquele documento. Seis novos taxa são dados para os Açores: Vitreolina curva (Monterosato, 1874), Nassarius cf. ovoideus (Locard, 1886), Mangelia coarctata (Forbes, 1840), Raphitoma leufroyi (Michaud,1838), Coryphela sp. and Pseudochama gryphina (Lamarck, 1819). O número total de moluscos marinhos das águas pouco profundas dos ilhéus das Formigas ascende agora a 88 taxa (1 Polyplacophora, 66 Gastropoda, 20 Bivalvia e 1 Cephalopoda).
- Checklist of the shallow-water marine molluscs of the Azores: 1 - Pico, Faial, Flores and CorvoPublication . Ávila, Sérgio P.; Azevedo, José M. N.; Gonçalves, João M.; Fontes, Jorge; Cardigos, FredericoAn up-to-date commented check-list of the shallow-water marine molluscs of Pico, Faial, Flores and Corvo islands (Azores, Portugal) is provided, based on literature records, on material deposited at the Department of Biology of the University of the Azores (DBUA) as a result of the scientific expeditions "Flores/89", "Açores/89" and "Pico/91", and on photographic material at the Department of Oceanography and Fisheries/University of the Azores (DOP/UA). The collections of the Museu Carlos Machado - Historia Natural, MCM-HN, of the Museu de Zoologia - Museu de Historia Natural da Faculdade de Ciencias e Tecnologia da Universidade de Coimbra, MZ/MHN-FCTUC, and the mollusc collection deposited at DOP/UA were surveyed and the results are included in this report. Two hundred and fifty five taxa of shallow-water molluscs are reported to Pico, Faial, Flores and Corvo Islands (196 Gastropoda, 50 Bivalvia and 9 Cephalopoda). Of these, 32 are dubious records (23 Gastropoda, 8 Bivalvia and 1 Cephalopoda), there remaining 197 confirmed species to these islands. A total of 26 taxa were identified only down to the genus level (25 Gastropoda and 1 Bivalvia).
- Checklist of the shallow-water marine molluscs of the Azores: 2 - São Miguel Island.Publication . Ávila, Sérgio P.; Azevedo, José M. N.; Gonçalves, João M.; Fontes, José; Cardigos, FredericoThis paper provides an updated checklist of the shallow-water marine molluscs of São Miguel island, based on the data from the bibliography and in the species collected from 1989 on by the Marine Biology teams of the University of the Azores (Ponta Delgada) and of the Department of Oceanography and Fisheries (Horta). The collections of the Museu Carlos Machado - História Natural (MCM-HN), of the Museu de Zoologia - Museu de História Natural da Faculdade de Ciências e Tecnologia da Universidade de Coimbra (MZ/MHN-FCTUC) and the image bank of DOP/UA, Department of Oceanography and Fisheries of the University of the Azores (ImagDOP), were also surveyed and the results are here reported. A total of 235 taxa of shallow water marine molluscs are reported to Slo Miguel island (4 Polyplacophora, 167 Gastropoda, 61 Bivalvia and 3 Cephalopoda). Of these, 10 are dubious records (7 Gastropoda and 3 Bivalvia), there remaining 225 confirmed taxa in this island. A total of 18 taxa were identified only down to the genus level (17 Gastropoda and 1 Bivalvia). Fifteen species are cited for the first time to the Azores: Dikoleps cf. cutleriana (Clark, 1848), (Bouchet & Guillemot, 1978), Cirsotrema cochlea (Sowerby G.B. II, 1844), Opalia bellenica (Forbes, 1844), Bela laevigata (Philippi, 1836), Odostomia nitens Jeffreys, 1870, Gregariella semigranata (Reeve, 1858), Modiolus adriaticus (Lamarck, 1836), Rhomboidella prideauxi (Leach, 1815), Lima lima (Linnaeus, 1758), Kellia cf. suborbicularis (Montagu, 1803), Astarte cf. sulcata (da Costa, 1778), Tellina pygmaea Loven, 1846, Venus nux Gmelin, 1791 and Thracia papyracea (Poli, 1791).
- D. João de Castro Bank, a shallow water hydrothermal-vent in the Azores: checklist of the marine molluscs.Publication . Ávila, Sérgio P.; Cardigos, Frederico; Santos, Ricardo S.D. João de Castro Bank (DJC) is a shallow seamount with hydrothermal activity located between the islands of Terceira and São Miguel, Azores (Portugal). Due to its remote location, few investigators have worked in the area. Thirty-three species of marine molluscs are recorded as new for DJC which brings the total number of species to 42 for this specific area. Common micro-mollusc species known for the Azores (e.g.: the sublittoral species Alvania poucheti and Setia subvaricosa) are not present, and possible reasons for this are discussed.
- In situ observation of sexual reproduction of Holothuria tubulosa Gmelin 1788 (Echinodermata: Holothuroidea) in the Azores (NE Atlantic)Publication . Andrade, Áthila A.; Machado, Leonardo F.; Barreiros, João P.; Paulay, Gustav; Cardigos, Frederico[...]. In the Azores, H. tubulosa spawning occurs in the summer months (so far observed in July and August) during the afternoon, which may follow the annual pattern, during warm sea temperatures (22–26°C) and being synchronous in both sexes, as stated by Despalotovic et al. (2004) in the Adriatic Sea. [...]
- Juvenile Sphyraena viridensis, preyed by the lizard fish Synodus saurus. A new predatory association from the AzoresPublication . Barreiros, João P.; Cardigos, Frederico; Soares, Marta S. C.; Machado, Leonardo F.Les juvéniles de Sphyraena viridensis, proies de Synodus saurus, une nouvelle association prédateur-proie aux Açores. Au cours d’un travail sur l’écologie (comportement, alimentation et reproduction) du poisson lézard, Synodus saurus, aux Açores (Atlantique NE) nous avons découvert, dans plusieurs contenus stomacaux, des exemplaires postlarvaires et des juvéniles de la bécune à bouche jaune Sphyraena viridensis. Non seulement cette découverte nous a permis d’obtenir, pour la première fois, des postlarves de cette espèce de barracuda mais nous avons réussi à décrire une action de prédation d’un poisson épibenthique envers une espèce pélagique.
- Non-indigenous marine species of the AzoresPublication . Cardigos, Frederico; Tempera, Fernando; Ávila, Sérgio P.; Gonçalves, João M.; Colaço, Ana; Santos, Ricardo S.Marine benthic species introduced to the Azores are collated from scientific publications, internal reports and own data. Twelve algae and 21 invertebrates are classified as non-indigenous species, 18 as cryptogenic. Two species of algae and two ascidians are regarded as particularly invasive along the shores of this oceanic archipelago.
- Taxonomic review of selected invertebrate groups collected during the Campaigns of the Prince Albert I of Monaco in the Azorean waters.Publication . García-Diez, Cristina; Porteiro, Filipe M.; Meirinho, Ana; Cardigos, Frederico; Tempera, FernandoIn the late 19th and early 20th centuries Prince Albert I of Monaco promoted 13 cruises that sampled the Azorean waters. During those cruises a total of 2624 nominal marine species were reported in the area. This work assembles the biological data provided by these expeditions to the Azores in a geo-referenced database. Faunal lists for seven invertebrate groups (Echiura, Sipuncula, Cephalopoda, Annelida, Brachiopoda, Chaetognatha and Echinodermata) are compiled. The checklist includes 331 nominal species, of which 310 are valid names: 1 echiurid; 11 sipunculids; 32 cephalopods; 130 annelids; 4 brachiopods; 14 chaetognaths; and 118 echinoderms. Eighteen percent are synonyms, 29% of the species were allocated to a different genus, 2.8% were misspellings and corrections due to gender or concordance rules, 0.8% were specific epithets allocated to sub-specific level or vice-versa, the rest were validated directly (without any modification in their nomenclature).
