  • Sea turtles : University of Florida – University of the Azores connection 1984 – present. A review
    Publication . Martins, Helen R.; Bjorndal, Karen A.; Ferreira, Rogério L.; Parra, Hugo Alexandre Esteves; Pham, Christopher K.; Rodríguez, Y.; Santos, M. R.; Vandeperre, Frederic; Bolten, Alan B.
    The loggerhead (Caretta caretta) is the most common sea turtle in the Azores. Since they do not nest in the area, a tagging program was started in the 1980’s to try to discover their origin. The result based on size distribution, suggested that they mainly are coming from beaches in SE United States. A collaboration between University of Florida and the University of the Azores began in 1984 in order to proceed with further research.
  • Lecanogaster gorgoniphila, a new species of clingfish (Teleostei: Gobiesocidae) from São Tomé and Principe, eastern Atlantic Ocean
    Publication . Fricke, Ronald; Wirtz, Peter
    The clingfish Lecanogaster gorgoniphila new species, an unusual species associated with gorgonians, is described on the basis of 7 specimens and colour photographs from São Tomé Island, São Tomé and Principe, eastern Atlantic Ocean. The species is small, probably not exceeding 28 mm total length; it is characterized by having 4-5 dorsal-fin rays, 3-4 anal-fin rays, 21-23 pectoral-fin rays, and 11-14 principal caudal-fin rays; 12-14 rakers on third gill arch, very small, partially fused; papillae in centre of pelvic disk forming a round patch; pelvic disc region B with 5-6 rows of papillae; head relatively short, its length 2.4-3.4 in SL, and relatively narrow, its width 4.5-7.4 in SL; colouration of head and body variable in life, usually dorsally reddish white, ventrally rose, with eight bright red bars with scattered white spots. The new species is compared with other species of the eastern Atlantic genera Lecanogaster and Diplecogaster; a key to the species of the genus Lecanogaster Briggs, 1957 is presented.
  • First record of the Mediterranean asteroid Sclerasterias richardi (Perrier in Milne-Edwards 1882) in the Azores Archipelago (NE Atlantic Ocean)
    Publication . Madeira, Patrícia; Martins, António M. de Frias; Ávila, Sérgio P.
    The first occurrence of the Mediterranean fissiparous asteroid Sclerasterias richardi (Perrier in Milne-Edwards 1882) is reported from the Azores based upon dredged material off the south coast of São Miguel Island at 135 m depth. This record represents a considerable expansion of the species’ geographic range, otherwise reported with certainty only from the Mediterranean Sea. S. richardi is capable of producing long-lived planktotrophic larvae with high dispersal potential to reach remote areas such as the Azores. Alternatively, this species is also capable of reproducing asexually through fission, which could insure the maintenance of viable numbers in a stranded population. The presence of S. richardi in Azorean waters and its rarity in an otherwise thoroughly investigated area does not necessarily imply a recent arrival nor a human-mediated introduction, as the depths in consideration (80-700 m) are also the least studied in the archipelago.
  • First record of the starfish Luidia atlantidea in the Canary Islands
    Publication . Osaer, Filip; Narváez, K.
    We document the first observations of Luidia atlantidea Madsen, 1950 (Luidiidae; Paxillosida, Asteroidea) along the coasts of the Canary Islands, which represents a new westward occurrence of its known range. Individuals were observed during a visual scuba diving census in the islands of Gran Canaria (northwestern and eastern coasts) and Tenerife (eastern coast). These occurrences highlight the importance of the systematic biodiversity monitoring and surveillance of the dynamic changes in the environment, whereas future research is required to reveal the underpinnings for its presence.
  • The importance of generalist pollinator complexes for endangered island endemic plants
    Publication . Weissmann, Julie A.; Schaefer, Hanno
    To investigate whether endangered endemic plants of the Azores are threatened by pollinator limitation, we studied the insect pollinator communities of Azorina vidalii, Euphrasia azorica, Myosotis azorica and Solidago azorica on Corvo Island. We found no evidence for dependence on a specialised pollinator. Instead, we found five to 21 mostly generalist insect pollinators per plant species, six of them probably introduced species. Diptera, with at least 12 species, and Hymenoptera, with at least nine species, are the most important insect orders and also most important in visitation frequency. The relatively high pollinator diversity for each of the studied plants and the high proportion of generalists indicate that the pollination networks of the four study plant species are rather resilient, i.e. the loss of a species would not constitute an immediate threat. Seed counts and numbers of juvenile plants indicate that reproductive success of all four species is stable. Altogether, our results suggest that there is no pollinator limitation in the four study species. Conservation measures should therefore focus on other threats, on Corvo mainly on grazing pressure.
  • New records of marine invertebrates from São Tomé and Príncipe (Eastern tropical Atlantic)
    Publication . Wirtz, Peter
    The following species are recorded from the coasts of São Tomé and Príncipe for the first time: the ciliate Zoothamnium niveum, the black coral Antipathella wollastoni, the zoanthid Isaurus tubercularis, and the shrimp Latreutes fucorum. The presence of the black coral Tanacetipathes spinescens and of the shrimp Cinetorhynchus rigens is confirmed. The presence of the crab Platypodiella picta at São Tome Island is confirmed and a possibly undescribed species of Platypodiella is recorded from Príncipe Island. Mistaken records of Stichopathes lutkeni are corrected: the species at São Tomé and Príncipe is Stichopathes occidentalis.
  • New records of moths (Insecta, Lepidoptera) from urban gardens on Terceira Island with new data on recently introduced species to the Azores
    Publication . Pérez Santa-Rita, Jose V.; Ros-Prieto, A.; Vieira, Virgílio; Karsholt, Ole; Gabriel, Rosalina; Borges, Paulo A. V.
    The urban Duque da Terceira Garden, in the main town of Angra do Heroísmo (Terceira, Azores), was investigated to describe the species composition of moths (Insecta, Lepidoptera). Moths were sampled with two methods: SLAM traps (between April and September 2017) and light trapping (two sessions in the summer of 2017). A total of 42 taxa were sampled with the addition of 19 new records for Duque da Terceira Garden, five of which were also new records for Terceira Island. The five species recorded as new for Terceira were subjected to an exhaustive taxonomic analysis. In addition, we revised the colonization status of some species. Our results show that urban gardens may help the establishment of exotic species and that it is necessary to monitor and control how these species established in urban environments.
  • New and confirmed records of fishes from the Cabo Verde archipelago based on photographic and genetic data
    Publication . Freitas, Rui; Falcón, J. M.; González, José A.; Burnett, K. A.; Dureuil, M.; Caruso, J. H.; Hoving, H. J. T.; Brito, A.
    In recent decades the Cabo Verde ichthyofauna has been studied more extensively, and nowadays photo-recording is employed as a valuable asset under special caution and consideration. Four species reported here are new records for Cabo Verde: Carlarius sp., sea catfish; Serranus cabrilla, comber; Branchiostegus semifasciatus, African tilefish and Lutjanus dentatus, African coastal snapper. The presence in Cabo Verde of Glaucostegus cemiculus, blackchin guitarfish, Elops senegalensis, Senegalese ladyfish, Lophius spp., bathydemersal monkfishes, Rachycentron canadum, cobia, Pagrus auriga, African seabream, Lutjanus dentatus, African coastal snapper and Mugil cephalus, mullet, was re-confirmed by photo-records. Squalus megalops, cosmopolitan spurdog, was identified by genetic fingerprinting. The two littoral species, P. auriga and M. cephalus, are firmly established in the archipelago and additional information on their occurrence is given. The findings reported in the present contribution may well be the result of a wider sharing of information between fishermen and other seafarers and scientists, rather than an indicator of recent faunal changes.
