Abstract

Background

Until today, a complete checklist of Bryozoa of the Greek seas had never been published and species records were scattered in several taxonomic and ecological studies. The aim of this paper is to produce a first checklist of marine bryozoan species of Greece, in the framework of the Greek Taxon Information System (GTIS) initiative of the LifeWatchGreece Research Infrastructure (ESFRI), by reviewing the existing literature and following the recent trends in the taxonomy of this group. 

New information

The marine bryozoan fauna of Greece comprises 237 species, classified in 127 genera, 66 families, 3 orders, and 2 classes. The vast majority belongs to the class Gymnolaemata (177 Cheilostomatida and 21 Ctenostomatida), while the remaining 39 species are Stenolaemata (all Cyclostomatida). Among these species, 12 are considered endemic to the eastern Mediterranean, while another 12 species are non-indigenous.

Keywords

Biodiversity, Aegean Sea, Sea of Crete, Levantine Sea, Ionian Sea, Eastern Mediterranean.

Introduction

The Mediterranean bryozoan fauna represents about 9.6% of the known global diversity of Bryozoa (Rosso and Di Martino 2016). However, current knowledge on the bryozoan fauna of this basin is highly biased due to differences in research effort for different taxa, marine areas and habitat types. Recent efforts in the south-eastern Mediterranean Sea have significantly increased our knowledge from areas which were previously considered “data-poor” spots for bryozoans, revealing a considerable proportion of non-indigenous taxa (e.g. Harmelin et al. 2016, Sokolover et al. 2016). Furthermore, information on Bryozoa from several Mediterranean areas is fragmented in old publications and grey literature; the collation of updated checklists (e.g. Koçak and Aydın Önen 2014) by experts could contribute to the mapping of diversity for understudied taxa and areas (Bailly et al. 2016, this special collection).

Sporadic records of bryozoans from the Aegean Sea can be found in old taxonomic studies, including the descriptions of the cheilostome species Calpensia nobilis, Hippaliosina depressa and Watersipora cucullata from this marine region (Busk 1854), based on material collected from shallow water macroalgae by E. Forbes. The first studies focusing on Bryozoa of the eastern Mediterranean basin, the Greek seas included, took place in the late 1960s (Harmelin 1969), based on material that was collected with dredges during the oceanographic expedition of the French research vessel “Jean Charcot” (1968). A total of 101 species belonging to all the 3 living bryozoan orders, were found, including several new records for the Mediterranean fauna. Later, the taxonomic study by Hayward (1974) on the cheilostome Bryozoa of Chios Island (north-eastern Aegean) yielded 101 species, including rare records and new species. Sharing only 47 cheilostomes with Harmelin’s list mentioned above, this study increased the eastern Mediterranean bryozoan diversity by 54 species.

More recently, few taxonomic and ecological studies have focused on the bryozoan fauna of Greece (e.g. Castritsi-Catharios and Marcopoulou-Diacantoni 1983, Castritsi-Catharios and Kiortis 1984, Castritsi-Catharios and Kiortis 1985, Castritsi-Catharios et al. 1985a, Castritsi-Catharios et al. 1985b, Castritsi-Catharios et al. 1986a, Castritsi-Catharios et al. 1986b, Castritsi-Catharios and Ganias 1989, Ganias 1990), while a considerable number of records has been included in general ecological studies examining a variety of habitats (e.g. Simboura et al. 1995, Conides et al. 1999, Morri et al. 1999, Antoniadou and Chintiroglou 2005, Gerovasileiou et al. 2013, Gerovasileiou et al. 2015). A complete checklist of Bryozoa however had never been published from Greece. The aim of the present study is to give a first annotated checklist of Bryozoa from the Greek seas.

Materials and methods

The checklist presented in this paper was compiled in the framework of the Greek Taxon Information System (GTIS), an initiative of the LifeWatchGreece Research e-Infrastructure aiming to produce a complete inventory of the known biodiversity of Greece (Bailly et al. 2016, this special collection). As this is the first attempt to compile a checklist of bryozoan diversity of the Greek seas, we performed an exhaustive literature review of bryozoan records. All taxa were cross-checked for synonymies and dubious records against the World List of Bryozoa (recent and fossil), the World Register of Marine Species (Bock and Gordon 2016, WoRMS Editorial Board 2016), and the recent update of the Mediterranean bryozoan diversity by Rosso and Di Martino (2016). Taxa identified as cf., as well as those left in open nomenclature, and fossil records were not included in the list. The checklist is annotated with the literature references reporting the presence of each species from Greek waters, as well as with notes on the nomenclature of some taxa. Non-indigenous bryozoans are also marked (NIB). The checklist follows the alphabetical order.

Genus Schizomavella Canu & Bassler, 1917

Schizomavella rudis (Manzoni, 1869)

Notes: 

In the absence of type material, the validity of S. rudis has been questioned by Reverter-Gil et al. (2012). Two new species, Stephanotheca watersi Reverter-Gil, Souto & Fernandez-Pulpeiro, 2012 and Schizomavella adriatica Reverter-Gil, Souto, Novosel & Tilbrook, 2016 have been erected to allocate some records from the western Basin and the Adriatic, respectively. Nevertheless, records and material from the Aegean were not considered and hence they are provisionally still reported as S. rudis (see also Rosso and Di Martino 2016).

Schizomavella (Calvetomavella) discoidea (Busk, 1859)

Notes: 

Harmelin 1969, Hayward 1974, Morri et al. 1999; the status of these records needs to be checked (see Rosso and Di Martino 2016​).

Schizomavella (Schizomavella) asymetrica (Calvet, 1927)

Nomenclature: 

Synonym valid for Calyptotheca triarmata Hayward, 1974 (see Rosso et al. 2010​).

Notes: 

Hayward 1974

Schizomavella (Schizomavella) cornuta (Heller, 1867)

Notes: 

Harmelin 1969, Hayward 1974, Castritsi-Catharios and Ganias 1989, Ganias 1990, Simboura et al. 1995, Morri et al. 1999; Mediterranean colonies recorded as S. auriculata, S. auriculata cuspidata and S. cuspidata possibly belong to this species.

Analysis

The bryozoan fauna of the Greek seas consists of 237 species, classified into 127 genera, 66 families, 3 orders, and 2 classes (Suppl. material 1). The vast majority belongs to the class Gymnolaemata, comprising 198 species (177 Cheilostomatida and 21 Ctenostomatida) and the remaining 39 species are Stenolaemata (all Cyclostomatida). The families with the highest number of species belong to Cheilostomatida, and are Phidoloporidae (16 species), Celleporidae (14 spp.), Bugulidae (12 spp.), Calloporidae (12 spp.), Smittinidae (11 spp.), Candidae (10 spp.), and Cribrilinidae (10 spp.). These families are the most speciose in the Mediterranean Sea as well (Rosso and Di Martino 2016). All other families include less than 10 species each.

All species included in the checklist are recognized in the World List of Bryozoa and the World Register of Marine Species, except for three of them. These are: Idmidronea triforis (Heller, 1967) and I. coerulea Harmelin, 1976, allocated within the genus Idmidronea Canu and Bassler, 1920 and not Exidmonea David, Mongereau and Pouyet, 1972; 'Microecia' occulta (Harmelin, 1976), provisionally left in its former allocation because the characters of the species differ from those of the genus Oncousoecia Canu, 1918 that has been suggested for its allocation (although Microecia Canu, 1918 is recognized as a synonym of Plagioecia Canu, 1918). The taxon Rhynchozoon sp. 1 sensu Hayward, 1974 described from Chios Island, was retained in the checklist following extensive lists by Zabala and Maluquer 1988, Rosso et al. 2010, Rosso and Di Martino 2016 and taxonomic papers with description and illustrations of material from Tyrrhenian and Adriatic localities (Chimenz Gusso et al. 2014).

A number of taxa were omitted from the present checklist (Table 1) for different reasons: (1) taxa now recognized as species complexes and considered absent from the Mediterranean; further examination of specimens is needed to ascertain their correct identification; (2) species whose currently accepted geographic distribution does not include the Mediterranean Sea; the examination of the material with the Scanning Electron Microscope could possibly raise the number of non-indigenous species in the Mediterranean basin; (3) species known exclusively as fossils from Tertiary sediments of Europe, whose persistence in the Mediterranean Sea throughout the Messinian Salinity Crisis needs to be ascertained.

Discussion

The bryozoan fauna of the Greek seas makes up 42.7% of the species, 59.9% of the genera and 71% of the families of the Mediterranean bryozoan fauna, specifically 41.7% of the Cheilostomatida, 36.8% of the Ctenostomatida and 52% of the Cyclostomatida species, based on the recent update by Rosso and Di Martino (2016). Despite the small number of sporadically distributed studies on this phylum in Greece, a considerable number of bryozoan species has been reported compared to adjacent eastern Mediterranean countries. A total of 185 species has been recorded from Turkey, 139 of which along the Aegean coasts (Koçak and Aydın Önen 2014) and 93 species from Lebanon (Harmelin et al. 2016), while 60 species were estimated to occur along the Mediterranean coasts of Israel (Sokolover et al. 2016). These numbers confirm the observed impoverishment of the bryozoan fauna from the western to the eastern basin (Harmelin et al. 2016).

Among the species reported from Greece, 12 are considered endemic to the eastern Mediterranean basin; these are the cheilostomes Adeonella pallasii, Calyptotheca rugosa, Cellepora posidoniae, Hippopodina ambita, Hippoporidra picardi, Monoporella bouchardii, Plesiocleidochasma mediterraneum, Reteporellina delicatula, Retevirgula akdenizae, Smittipora disjuncta, Therenia rosei and Turbicellepora camera. Of these, 5 species were first described from the island of Chios based on material collected by Hayward (i.e. C. rugosa, H. ambita, R. delicatula, T. rosei, and T. camera), H. picardi was described from the Gulf of Thessaloniki, while R. akdenizae was described from the Turkish coasts of the Aegean Sea. The cheilostome Hippaliosina depressa, which was described from the Aegean Sea, is considered more typical of the eastern Mediterranean basin, including the Sicily Strait, the western Ionian and south Adriatic seas (Harmelin et al. 2016 and references therein, AR personal observations). Nevertheless, this species was recorded in a few localities of western Corsica (Calvet 1902, Gautier 1962) and Sardinia (AR and E. Di Martino, personal observations) in the western Mediterranean.

Interestingly, three of the bryozoans recorded from Greece are typical of the North Atlantic (Hayward and Ryland 1998, Hayward and Ryland 1999) and have been rarely reported from the Mediterranean Sea. These are Alderina imbellis (Hincks, 1860), also reported from northern Catalonia (Madurell et al. 2013), Escharina johnstoni (Quelch, 1884), also reported from the western Ionian Sea (Rosso 1996a, Rosso 1996b, Rosso et al. 2014), and Anarthropora monodon (Busk, 1860).

The recent introduction of non-indigenous species, mostly lessepsian migrants, over the last decades, has considerably increased the number of bryozoans occurring in the Mediterranean Sea (Rosso and Di Martino 2016). Studies in the southeastern Mediterranean basin have brought to light a considerable number of NIBs (Harmelin 2014b, Gerovasileiou et al. 2016, Harmelin et al. 2016, Sokolover et al. 2016), mainly originated from the Red Sea/Indo-Pacific Ocean. Until today, 12 NIBs have been reported from the Greek seas, representing 5% of the bryozoan fauna of Greece and 20% of the Mediterranean NIB fauna; these are the ctenostomes Amathia gracillima and A. verticillata and the cheilostomes Bugula neritina, Bugulina fulva, Crepidacantha poissonii, Crisularia plumosa, C. serrata, Exechonella antillea, Hippopodina feegeensis, Microporella coronata, Parasmittina raigii, and Scrupocellaria scruposa.

Bryozoans from the Greek seas were reported from a variety of habitats, including soft sediments, seagrass leaves and rhizomes, macroalgae, coralligenous concretions and, to a smaller extent, from marine caves. Further research on bryozoan diversity in understudied habitats, typically species-rich in bryozoans (e.g. marine caves and coralligenous beds), is expected to increase our knowledge, possibly revealing additional new and non-indigenous species.
