- 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).
- First in situ observations of soft bottom megafauna from the Cascais Canyon headPublication . Gomes-Pereira, José N.; Tojeira, I.; Ribeiro, L. P.; Santos, Ricardo S.; Dias, F.; Tempera, FernandoWe report the first in situ observations of soft bottom megafauna from the Cascais Canyon head. Observations were collected opportunistically during three technical dives with the ROV Luso between 460-805 m at two locations distanced 1,230 m. The habitats were clas-sified as upper bathyal fine mud. The soft bottom fauna was dominated by burrows of Nephrops norvegicus reaching up to 2.9 burrows/m2, a common habitat along the Portu-guese continental margin. To our knowledge, densities are the highest ever reported for depths below 300 m. The ichthyofauna at the upper Cascais Canyon is a mixture of lower shelf and upper bathyal species, including Phycis blennoides, Scyliorhynus canicula, Coe-lorhynchus labiatus/occa and Chimaera monstrosa. Bait release attracted Myxine glutinosa. Surveys in other geological settings of the Cascays Canyon are required to understand more comprehensively the diversity of its sessile and vagile biodiversity.
- New occurrences of Corallium spp. (Octocorallia, Coralliidae) in the Central Northeast AtlanticPublication . Sampaio, Íris; Ocaña, Óscar; Tempera, Fernando; Henriques, Andreia Braga; Matos, Valentina; Porteiro, Filipe M.Corallium niobe Bayer, 1964 and Corallium tricolor (Johnson, 1899) are reported as new records from the central Northeast Atlantic. C. niobe was caught in the Azores and C. tricolor on the slope of the Irving Seamount (South Azores Seamounts). The presence of Corallium johnsoni Gray, 1860 in Azorean waters is confirmed. The sub-tropical Macaronesian islands and seamounts appear to be an important hot-spot for Corallium spp. Most colonies have been collected on seamounts and island slopes around Madeira, Canaries, Azores and the Cape Verde archipelagos. In the Azores most of these corals live below the normal depth of commercial fishing operations and are unlikely to be severely impacted by this activity.
- 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.
- Notes on fauna associated with an opportunistic artificial reef near cold-water coralsPublication . Gomes-Pereira, José N.; Tempera, Fernando; Ribeiro, P. A.; Porteiro, Filipe M.This short communication provides a sporadic insight on the importance of a hard three-dimensional structure for deepwater fish near CWC. Fish size and behaviour inside the structure and in the surrounding area are described. Additionally, a list of biofouling macroorganisms found on the structure after one year of deployment is presented.
- On some interesting opisthobranchs (Mollusca, Gastropoda) from the Azores.Publication . Fontes, Jorge; Tempera, Fernando; Wirtz, PeterThe nudibranch Eubranchus farrani Alder and Hancock, 1844 is recorded from the Azores for the first time. The presence of the sacoglossan Placida cremoniana (Trinchese, 1892) in the Azores is confirmed. Pleurobranchus sp. from the Azores, Madeira and the Canary Islands is compared with P. garciagomesi Cervera et al. 1996; it probably is an undescribed species.
- 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).
