    Decapod crustaceans on the Gokceada (Imbros) island continental shelf (north-eastern Aegean Sea)
    (Natl Centre Marine Research, 2006) Ates, A. S.; Katagan, T.; Kocatas, A.; Sezgin, M.
    The present composition of decapod crustaceans found at the sublittoral depths (5-104 m) off the coast of the island of Gokceada (north-eastern Aegean Sea) is presented. A total of 28 species (11 caridean shrimps, 1 thalassinid ghost crab, 7 anomurans and 9 brachyuran crabs) and 277 specimens were recorded. The caridean shrimp, Athanas nitescens had the highest abundance with a dominance value of 20.94% in samples. The dominant group is caridean, represented by a total of 11 species and an occurrence frequency of 39.29%.

    (Natl Centre Marine Research, 2008) Ozcan, T.; Ates, A. S.; Katagan, T.
    The indo-Pacific mantis shrimp, Erugosquilla massavensis was recently collected from Sigacik Bay, located on the Aegean coast of Turkey. It is the first record of the species along the Aegean coast of Turkey

    First record of the red shrimp, Aristeus antennatus (Risso, 1816) (Decapoda: Aristeidae) from the Aegean Sea coast of Turkey
    (Natl Centre Marine Research, 2009) Ozcan, T.; Irmak, E.; Ates, A. S.; Katagan, T.
    A female specimen of the deep-water red shrimp, Aristeus antennatus (Risso, 1816) was caught at depths of between 550 m and 670 m during 2005 by trawling off the Marmaris coast. A. antennatus is a species known to inhabit only the Levantine Sea coast of Turkey. This paper is on the first record of the species along the southern Aegean Sea coast of Turkey

    LIKELY EFFECTS OF GLOBAL CLIMATE CHANGE ON THE BLACK SEA BENTHIC ECOSYSTEM
    (Scibulcom Ltd, 2010) Sezgin, M.; Bat, L.; Katagan, T.; Ates, A. S.
    Occurrence and distribution of species in the Black sea are primarily determined by seawater temperature and salinity. The most recent predictions suggest that, by 2100, average air temperatures may be between 2 and 4 degrees C higher than at present and seawater temperatures may be as much as 2 degrees C higher than in 2000. The rise of the coastal zone seawater temperature may be higher than the open sea water average. It is expected that a warming of air and seawater temperatures will result in increased diversity of benthic marine life in the Black sea with adverse effects limited mainly to declines in abundance or loss of a small number of native species. Changes to a minority of biotopes might occur in the long-term. Depending on the temperature increase Mediterranisation of the Black sea fauna is in progress and occurs owing to immigration of new species. The aim of this article is discussing the global warming and the range of likely effects on marine benthic species. These effects may be related to changing water temperatures, changing water circulation or changing habitat. At present, to predict or detect the effects of climate change on marine benthic communities are quite difficult. But we can only provide educated guesses about potential changes and the consequences of those changes for the Black sea.

    New Mediterranean Marine biodiversity records (June 2013)
    (Natl Centre Marine Research, 2013) Siokou, I.; Ates, A. S.; Ayas, D.; Ben Souissi, J.; Chatterjee, T.; Dimiza, M.; Durgham, H.
    This paper concerns records of species that have extended their distribution in the Mediterranean Sea. The finding of the rare brackish angiosperm Althenia filiformis in the island of Cyprus is interesting since its insertion in the Red Data Book of the Flora of Cyprus is suggested. The following species enriched the flora or fauna lists of the relevant countries: the red alga Sebdenia dichotoma (Greece), the hydrachnid mite Pontarachna adriatica (Slovenia), and the thalassinid Gebiacantha talismani (Turkey). Several alien species were recorded in new Mediterranean localities. The record of the burrowing goby Trypauchen vagina in the North Levantine Sea (Turkish coast), suggests the start of spreading of this Lessepsian immigrant in the Mediterranean Sea. The findings of the following species indicate the extension of their occurrence in the Mediterranean Sea: the foraminifer Amphistegina lobifera (island of Zakynthos, Greece), the medusa Cassiopea andromeda (Syria), the copepod Centropages furcatus (Aegean Sea), the decapod shrimp Melicertus hathor (island of Kastellorizo, Greece), the crab Menoethius monoceros (Gulf of Tunis), the barnacles Balanus trigonus, Megabalanus tintinnabulum, Megabalanus coccopoma and the bivalves Chama asperella, Cucurbitula cymbium (Saronikos Gulf, Greece).

    New records of Decapod Crustaceans (Decapoda: Pontoniinae and Inachidae) associated with sea anemones in Turkish waters
    (Natl Centre Marine Research, 2013) Duris, Z.; Ates, A. S.; Ozalp, H. B.; Katagan, T.
    Three anemone-associated decapod crustaceans, two shrimp species, Periclimenes amethysteus and P. aegylios (Caridea: Palaemonidae: Pontoniinae), and the crab Inachus phalangium (Brachyura: Inachidae), all collected from the Dardanelles, are reported for the first time from Turkish coasts. Another inachid crab, Macropodia czernjawskii, is also reported for the first time to occur in association with the sea anemone Anemonia viridis. Periclimenes scriptus was the fifth decapod species recorded associated with sea anemones within the framework of the present study, and while this species has already been reported from Turkish waters, this is the first time it is recorded from the Dardanelles (the Turkish Straits System).

    Seasonal Effects of Environmental Variables on Molluscan Communities in cardak Lagoon (Turkish Straits)
    (Maik Nauka/Interperiodica/Springer, 2023) Ates, A. S.; Dogan, A.; Acar, S.; Buyukates, Y.; Dagli, E.; Bakir, A. K.; Mulayim, A.
    In the present study, the effects of environmental variables on the community of molluscans found in a protected lagoon system (cardak Lagoon, Dardanelles) polluted by domestic waste were investigated. Samplings were performed from sandy and silty bottoms of the study area between the depths of 1 and 1.8 m in October 2018, February, April, and June 2019. A total of 14954 specimens and 59 molluscan species (2 Polyplacophora, 30 bivalves, and 27 gastropods) were found, with two exotic species, Arcuatula senhousia and Ruditape sphilippinarum. Highest gastropod abundance was observed in autumn 2018, while the highest bivalves abundance was in spring 2019. Considering environmental variables, gravel content had highest correlation with Shannon-Weaver and Turkish Biotic Index values. In addition, anionic detergent derived from domestic pollution affected diversity. Environmental variables of anthropogenic origin were found to modify the community structure at high level. Dissolved oxygen, oxygen reduction potential, nitrite + nitrate, and chemical oxygen demand concentrations in water, and sand content in sediment were important variables affecting the distribution of molluscan species in the study area.
