Alge grčkih obala: Rhodophyta: Ceramiales

An updated checklist of the red seaweeds (Rhodophyta) of the Order Ceramiales of the Greek coasts is provided, based on literature records, critically reviewed from present-day taxonomic and nomenclatural aspects. The total number of genera, species and infraspecific taxa currently accepted is 60, 118 and 2, respectively. The occurrence of each taxon in the North Aegean, South Aegean and Ionian Seas is given. Knowledge gaps are pointed, with 70 taxa pending confirmation of their presence marked. Moreover, 15 excludenda and 20 inquirenda taxa are briefly discussed. In this paper is given an updated base of the Ceramiales taxa occurrence in Greece, needed for future targeted seaweed studies.Ažurirani popis crvenih algi (Rhodophyta) iz reda Ceramiales na grčkim obalama napravljen je na temelju zapisa iz stručne literature i kritički je preispitan s današnjih aspekata taksonomije i nomenklature. Ukupan broj rodova, vrsta i intraspecijskih taksonomskih kategorija koje su danas prihvaćene je 60, 118, odnosno 2. Prikazana je pojava svake svojte u sjevernom i južnom Egejskom moru te u Jonskom moru. Ukazano je na propuste u dosadašnjim istraživanjima, uključivo za 70 svojti za koje je u tijeku potvrda da je zabilježena njihova prisutnost. Štoviše, u raspravi su izneseni podaci o 15 neprihvaćenih i problematičnih svojti kao i o 20 svojti upitnog i sumnjivog taksonomskog statusa. U ovom radu su prikazani ažurirani podaci o pojavljivanju crvenih algi Ceramiales u Grčkoj, a koji su neophodni za izradu budućih ciljanih studija

Morske alge grčke obale: Rhodophyta bez Ceramiales

An updated checklist of the red seaweeds (Rhodophyta), excluding the order Ceramiales, of the Greek coasts is provided, based on literature records, critically reviewed from present-day taxonomic and nomenclatural aspects. The total number of genera, species and infraspecific taxa currently accepted is 78, 138 and 4 respectively. The occurrence of each taxon in the North Aegean, South Aegean and Ionian Seas is given. Knowledge gaps are pointed, with 57 taxa pending confirmation of their presence marked. Moreover, 13 excludenda and 12 inquirenda taxa are briefly discussed. In overall, a solid updated baseline of the Rhodophyta (excluding Ceramiales) taxa occurence in Greece is provided, critical for future tailor-targeting seaweed studies.U radu autori prikazuju ažurirani popis crvenih morskih algi grčkih obala (Rhodophyta), isklju-čujući red Ceramiales, koji se temelji na literaturnim zapisima, te je kritički pregledan s današnjih taksonomskih i nomenklaturnih aspekata. Ukupan broj rodova, vrsta i infraspecifičnih taksona koji su trenutno prihvaćeni je 78, 138 i 4, respektivno.Prikazana je pojava svake svojte u sjevernom i južnom Egejskom moru i u Jonskom moru. Uoče-ne su praznine u znanju, tj. s 57 taksona koji čekaju potvrdu njihove prisutnosti. Štoviše, ukratko se raspravlja o 13 isključenih i 12 ispitivanih svojti. U cjelini, osigurana je čvrsta ažurirana osnovica pojavljivanja Rhodophyta (isključujući Ceramiales) u Grčkoj, što je presudno za buduće studije usmjerene na ciljane vrste

Further expansion of the alien seaweed Caulerpa taxifolia var. distichophylla (Sonder) Verlaque, Huisman & Procacini (Ulvophyceae, Bryopsidales) in the Eastern Mediterranean Sea

We are grateful to Andreas Antoniou (Dep. of Environment, Ministry of Agriculture, Rural Development & Environment, Cyprus) for his assistance in the preparation of the illustrations. We would also like to thank Dr. Sotiris Orfanidis (NAGREF – Fisheries Research Institute, Kavala, Greece) for his valuable advice and both the DFMR and HSR / HCMR Rhodes crew and George Hatiris for their help in samplings. Special thanks are due to Dinos Leonidou (SeaQuest Divers Cyprus) for accompanying the deep dive for sampling Caulerpa at Cavo Greco. We are grateful to the Total Foundation (Paris) for its funding support to this study within the framework of the project “Brown algal ecology and biodiversity in the eastern Mediterranean Sea” and to the MASTS pooling initiative (Marine Alliance for Science and Technology for Scotland, funded by the Scottish Funding Council and contributing institutions; grant reference HR09011).Peer reviewedPublisher PD

Baseline Distribution of Invasive Alien Species of Union concern

A current EU geographical distribution of spatial information for the 37 Invasive Alien Species (IAS) of Union concern (IAS Regulation 1143/2014) is set, based on the best available knowledge, resulting from an assessment of data aggregated through the European Alien Species Information Network (EASIN) in collaboration with the Member States (MS) Competent Authorities of 18 EU countries. This baseline is an important tool supporting the implementation of the IAS Regulation and also provides a factual basis for the review of the application of the IAS Regulation. Ultimately, the information included can be used for monitoring the achievement of Target 5 of the EU Biodiversity Strategy to 2020 for combatting IAS, but also to the implementation of other EU policies with requirements on alien species, such as the Birds and Habitats Directives, and the Marine Strategy and Water Framework Directives.JRC.D.2-Water and Marine Resource
