Bruno Sabelli * E Stefano Tommasini * Introduzione
Boll. Malacologico I Milano' 18 I (9-12) I 291-300 I settembre-dicembre 1982 Bruno Sabelli * e Stefano Tommasini * OSSERVAZIONI SULLA RADULA E SULLA PROTOCONCA DI BOLINUS BRANDARIS (L" 1758) E PHYLWNOTUS TRUNCULUS (L" 1758) Introduzione La sottofamiglia M u r i c i n a e comprende in Mediterraneo so- lo poche specie, per la precisione sei, di cui una (Bolinus cornutus (L., 1758)) segnalata solo dubitativamente per il nostro mare, due (Mu- rex tribulus L., 1758 e Aspella anceps (LAMARCK,1822)) sono ospiti re- centissimi essendo penetrati e forse acclimatati si in Mediterraneo so- lo dopo l'apertura del canale di Suez (BARASHe DANIN, 1972, 1977; GHI- SOTTI,1974) mentre le altre tre si possono definire come autoctone. Poichè le tre specie esotiche sono state reperite solo in numero esi- guo di esemplari e comunque mai viventi non si hanno informazioni sulla loro radula e sulla microscultura della loro protoconca e noi non siamo stati in grado di colmare questa lacuna. Per quanto con- cerne le altre tre specie Dermomurex scalaroides (BLAINVILLE,1826) è stato ampiamente investigato sotto il profilo tassonomico da FRAN- CHINI (1977) che ne ha anche illustrato la radula; mancherebbero co- munque dati sulla sua protoconca, ma gli oltre trenta esemplari esa- minati di questa specie non si sono prestati per questo studio essen- do tutti con l'apice abraso per cui la questione rimane insoluta. Solo le ultime due specie: Bolinus brandaris (L., 1758) e Phyllonotus trun- culus (L., 1758), sono dunque state studiate e se pur poco rappresen- tative dell'intera sottofamiglia presentano comunque alcuni interes- santi problemi che ci hanno indotto a redigere questa nota. -

The analysis revealed 27 new records of brown algae for Hainan Island, including 5 species which also constitute new records for China. 21 of these species are de- scribed with photographs and an annotated list of all species with information on life forms, habitat (localities and tidal zones) and their geographical distribution is provided.

Denotations: (™) = Genotype @ = Associated to * = General note PHYLUM, CLASSIS, SUBCLASSIS, SUPERORDO, ORDO, SUBORDO, INFRAORDO, Superfamilia, Familia, Subfamilia, Genus & species N.B.: This is one of several preliminary check-lists, covering S Scandinavian marine animal (and partly marine protoctistan) taxa. Some financial support from (or via) NKMB (Nordiskt Kollegium för Marin Biologi), during the last years of the existence of this organization (until 1993), is thankfully acknowledged. The primary purpose of these checklists is to faciliate for everyone, trying to identify organisms from the area, to know which species that earlier have been encountered there, or in neighbouring areas. A secondary purpose is to faciliate for non-experts to put as correct names as possible on organisms, including names of authors and years of description. So far these checklists are very preliminary. Due to restricted access to literature there are (some known, and probably many unknown) omissions in the lists. Certainly also several errors may be found, especially regarding taxa like Plathelminthes and Nematoda, where the experience of the compiler is very rudimentary, or. e.g. Porifera, where, at least in certain families, taxonomic confusion seems to prevail. This is very much a small modernization of T. -
The Marine Macroalgae of Cabo Verde Archipelago: an Updated Checklist
Arquipelago - Life and Marine Sciences ISSN: 0873-4704 The marine macroalgae of Cabo Verde archipelago: an updated checklist DANIELA GABRIEL AND SUZANNE FREDERICQ Gabriel, D. and S. Fredericq 2019. The marine macroalgae of Cabo Verde archipelago: an updated checklist. Arquipelago. Life and Marine Sciences 36: 39 - 60. An updated list of the names of the marine macroalgae of Cabo Verde, an archipelago of ten volcanic islands in the central Atlantic Ocean, is presented based on existing reports, and includes the addition of 36 species. The checklist comprises a total of 372 species names, of which 68 are brown algae (Ochrophyta), 238 are red algae (Rhodophyta) and 66 green algae (Chlorophyta). New distribution records reveal the existence of 10 putative endemic species for Cabo Verde islands, nine species that are geographically restricted to the Macaronesia, five species that are restricted to Cabo Verde islands and the nearby Tropical Western African coast, and five species known to occur only in the Maraconesian Islands and Tropical West Africa. Two species, previously considered invalid names, are here validly published as Colaconema naumannii comb. nov. and Sebdenia canariensis sp. nov. Key words: Cabo Verde islands, Macaronesia, Marine flora, Seaweeds, Tropical West Africa. Daniela Gabriel1 (e-mail: [email protected]) and S.

In general, marine, biota—particularly in euphotic and dysphotic zones—depends directly or indirectly on light, but ultraviolet radiation (UV-R) can damage vital molecular machineries. UV-R induces the formation of reactive oxygen species (ROS) and impairs intracellular structures and enzymatic reactions. It can also affect organismal physiologies and eventually alter trophic chains at the ecosystem level. In Antarctica, physical drivers, such as sunlight, sea-ice, seasonality and low temperature are particularly influencing as compared to other regions. The springtime ozone depletion over the Southern Ocean makes organisms be more vulnerable to UV-R. -
