Octocoral Diversity of Balıkçı Island, the Marmara Sea
J. Black Sea/Mediterranean Environment Vol. 19, No. 1: 46-57 (2013) RESEARCH ARTICLE Octocoral diversity of Balıkçı Island, the Marmara Sea Eda Nur Topçu1,2*, Bayram Öztürk1,2 1Faculty of Fisheries, Istanbul University, Ordu St., No. 200, 34470, Laleli, Istanbul, TURKEY 2Turkish Marine Research Foundation (TUDAV), P.O. Box: 10, Beykoz, Istanbul, TURKEY *Corresponding author: [email protected] Abstract We investigated the octocoral diversity of Balıkçı Island in the Marmara Sea. Three sites were sampled by diving, from 20 to 45 m deep. Nine species were found, two of which are first records for Turkish fauna: Alcyonium coralloides and Paralcyonium spinulosum. Scientific identification of Alcyonium acaule in the Turkish seas was also done for the first time in this study. Key words: Octocoral, soft coral, gorgonian, diversity, Marmara Sea. Introduction The Marmara Sea is a semi-enclosed sea connecting the Black Sea to the Aegean Sea via the Turkish Straits System, with peculiar oceanographic, ecological and geomorphologic characteristics (Öztürk and Öztürk 1996). The benthic fauna consists of Black Sea species until approximately 20 meters around the Prince Islands area, where Mediterranean species take over due to the two layer stratification in the Marmara Sea. The Sea of Marmara, together with the straits of Istanbul and Çanakkale, serves as an ecological barrier, a biological corridor and an acclimatization zone for the biota of Mediterranean and Black Seas (Öztürk and Öztürk 1996). The Islands in the Sea of Marmara constitute habitats particularly for hard bottom communities of Mediterranean origin. Ten Octocoral species were reported by Demir (1954) from the Marmara Sea but amongst them, Gorgonia flabellum was probably reported by mistake and 46 should not be considered as a valid record from the Sea of Marmara. -

Wise Faculty of Life Sciences, Tel Aviv University, Ramat Aviv, Tel Aviv, 69978, Israel 2The Steinhardt Museum of Natural History and National Research Center, Tel Aviv University, Tel Aviv, Israel *Corresponding author E-mail: [email protected] Received: 5 May 2015 / Accepted: 24 November 2015 / Published online: 30 December 2015 Handling editor: Vadim Panov Abstract Environmental factors, such as temperature and salinity, are known to influence distribution patterns and invasion success in ascidians. The solitary ascidian Microcosmus exasperatus Heller, 1878 has a wide global distribution and can be found in both tropical and sub-tropical waters. In the Mediterranean Sea, it is considered to be an invasive species introduced through the Suez Canal, with a restricted distribution in the eastern Mediterranean. Despite its global distribution, the environmental tolerances of this species are poorly known. We examined the effect of varying temperature and salinity on the survival of adult individuals of M. exasperatus in a laboratory setting to partially determine its environmental tolerance range. In addition, it’s global and local distribution as well as the seasonal abundance in ‘Akko Bay (northern Mediterranean coast of Israel) were examined. Field observations and laboratory experiments show that M. exasperatus is able to tolerate a temperature range of 12–30 ºC, and salinity of 37–45, but it survived poorly in salinity of 33–35 and temperatures > 32 ºC. -

Ascidiacea (Chordata: Tunicata) of Greece: an Updated Checklist

Biodiversity Data Journal 4: e9273. https://doi.org/10.3897/BDJ.4.e9273 Abstract Background The checklist of the ascidian fauna (Tunicata: Ascidiacea) of Greece was compiled within the framework of the Greek Taxon Information System (GTIS), an application of the LifeWatchGreece Research Infrastructure (ESFRI) aiming to produce a complete checklist of species recorded from Greece. This checklist was constructed by updating an existing one with the inclusion of recently published records. All the reported species from Greek waters were taxonomically revised and cross-checked with the Ascidiacea World Database. New information The updated checklist of the class Ascidiacea of Greece comprises 75 species, classified in 33 genera, 12 families, and 3 orders. In total, 8 species have been added to the previous species list (4 Aplousobranchia, 2 Phlebobranchia, and 2 Stolidobranchia). Aplousobranchia was the most speciose order, followed by Stolidobranchia. Most species belonged to the families Didemnidae, Polyclinidae, Pyuridae, Ascidiidae, and Styelidae; these 4 families comprise 76% of the Greek ascidian species richness. The present effort revealed the limited taxonomic research effort devoted to the ascidian fauna of Greece, © Antoniadou C et al. -

General Introduction and Objectives 3
General introduction and objectives 3 General introduction: General body organization: The phylum Porifera is commonly referred to as sponges. The phylum, that comprises more than 6,000 species, is divided into three classes: Calcarea, Hexactinellida and Demospongiae. The latter class contains more than 85% of the living species. They are predominantly marine, with the notable exception of the family Spongillidae, an extant group of freshwater demosponges whose fossil record begins in the Cretaceous. Sponges are ubiquitous benthic creatures, found at all latitudes beneath the world's oceans, and from the intertidal to the deep-sea. Sponges are considered as the most basal phylum of metazoans, since most of their features appear to be primitive, and it is widely accepted that multicellular animals consist of a monophyletic group (Zrzavy et al. 1998). Poriferans appear to be diploblastic (Leys 2004; Maldonado 2004), although the two cellular sheets are difficult to homologise with those of the rest of metazoans. They are sessile animals, though it has been shown that some are able to move slowly (up to 4 mm per day) within aquaria (e.g., Bond and Harris 1988; Maldonado and Uriz 1999). They lack organs, possessing cells that develop great number of functions. The sponge body is lined by a pseudoepithelial layer of flat cells (exopinacocytes). Anatomically and physiologically, tissues of most sponges (but carnivorous sponges) are organized around an aquiferous system of excurrent and incurrent canals (Rupert and Barnes 1995). These canals are lined by a pseudoepithelial layer of flat cells (endopinacocytes).Water flows into the sponge body through multiple apertures (ostia) General introduction and objectives 4 to the incurrent canals which end in the choanocyte chambers (Fig. -

Internal phylogeny and relationships between Styelidae and Pyuridae 37 were inconclusive however. In order to clarify these points we used mitochondrial and 38 nuclear sequences from 31 species of Styelidae and 25 of Pyuridae. Phylogenetic trees 39 recovered the Pyuridae as a monophyletic clade, and their genera appeared as 40 monophyletic with the exception of Pyura. -

Bioconstructors provide habitats for a large variety of organisms and these organisms rely on bioconstructors as a source of food and shelter. Marine bioconstructors in temperate seas have been recognized to have a structural and functional role of marine biodiversity (as a habitat formers and ecosystem engineers), the same as coral reefs in tropical regions. Bioconstructors are ranging from coralligenous formations (formed usually by coralline algae, sponges, cnidarians, and bryozoans) to vermetid reefs, deep-sea white corals and oyster banks. Some habitats like coral banks formed by shallow-water coral Cladocora caespitosa od deep-water coral Lophelia pertusa , together with coralligenous buildups and maerl beds are of special interest for scientists and people involving with nature protection. Habitat degradation, destruction, fragmentation and loss are the most dramatic conse- quences of anthropogenic pressures on natural ecosystems and marine bioconstructors as a part of that. Under the present climate warming trend, together with marine acidifi cation, new mass mortality events may occur in the near future, possibly driving a major biodiver- sity crisis in the Mediterranean Sea,
