STAHEL Zoologiscbes Museum der Universitlit Zi~ricb; Ziirich, Scbweiz ABSTRACT: Environmental conditions affecting the occurrence of Astropecten aranciacus (Asteroidea, Echinodermata). In shallow water off the north coast of Sardinia (western Mediterranean) the frequency of occurrence of the starfish Astropecten aranciacus was recorded in 70 sample areas of 25 ms each. Four environmental factors, namely depth, average sand grain diameter, number of mollusc species, and number of individuals of the genus Echino- cardium proved to be related to the abundance of A. aranciacus. The sediment contained many species, each, as a rule, being present at low abundance. The molluscs found and their sizes are listed.

The Echinoderm Fauna of Turkey with New Records from the Levantine Coast of Turkey
Proc. of middle East & North Africa Conf. For Future of Animal Wealth THE ECHINODERM FAUNA OF TURKEY WITH NEW RECORDS FROM THE LEVANTINE COAST OF TURKEY Elif Özgür1, Bayram Öztürk2 and F. Saadet Karakulak2 1Faculty of Fisheries, Akdeniz University, TR-07058 Antalya, Turkey 2İstanbul University, Faculty of Fisheries, Ordu Cad.No.200, 34470 Laleli- Istanbul, Turkey Corresponding author e-mail: [email protected] ABSTRACT The echinoderm fauna of Turkey consists of 80 species (two Crinoidea, 22 Asteroidea, 18 Ophiuroidea, 20 Echinoidea and 18 Holothuroidea). In this study, seven echinoderm species are reported for the first time from the Levantine coast of Turkey. These are, five ophiroid species; Amphipholis squamata, Amphiura chiajei, Amphiura filiformis, Ophiopsila aranea, and Ophiothrix quinquemaculata and two echinoid species; Echinocyamus pusillus and Stylocidaris affinis. Turkey is surrounded by four seas with different hydrographical characteristics and Turkish Straits System (Çanakkale Strait, Marmara Sea and İstanbul Strait) serve both as a biological corridor and barrier between the Aegean and Black Seas. The number of echinoderm species in the coasts of Turkey also varies due to the different biotic environments of these seas. There are 14 echinoderm species reported from the Black Sea, 19 species from the İstanbul Strait, 51 from the Marmara Sea, 71 from the Aegean Sea and 42 from the Levantine coasts of Turkey. Among these species, Asterias rubens, Ophiactis savignyi, Diadema setosum, and Synaptula reciprocans are alien species for the Turkish coasts.

ZooKeys 663: 1–19. https://doi.org/10.3897/zookeys.663.11413 Abstract The first morphological observation of a euryalid brittle star,Asteronyx loveni, using non-destructive X- ray micro-computed tomography (µCT) was performed. The body of euryalids is covered by thick skin, and it is very difficult to observe the ossicles without dissolving the skin. Computed tomography with micrometer resolution (approximately 4.5–15.4 µm) was used to construct 3D images of skeletal ossicles and soft tissues in the ophiuroid’s body. Shape and positional arrangement of taxonomically important ossicles were clearly observed without any damage to the body. -
Morphometry and Areal Growth Cohorts of Common Epifaunal Species on a Sand Bottom of the Cilician Shelf (Turkey), Mediterranean Sea

The dimorphisms in the length-width-weight relationships were observed for the epibentic fauna due presumably to the sexes whereas biometrically dimorphic relationship was not structured for the common flat fishes. Maximum number of growth cohorts changed between >C2 (Buglossidium luteum) and >C4 (Arnoglossus laterna) for the flatfishes. Nine cohorts coexisted for a hermit crab, a crustacean species. Three muricid (Mollusca) species were classified with maximum number of cohort up to >C2 and the nassariid gastropods as well. A Lesepsian bivalve, Pinctada radiata displayed two growth cohorts, and three cohorts based on disc thickness of a seastar (Astropecten irregularis).

Dental Insights Into Ophiuroids: Feeding Mechanisms and Life Style
Dental insights into ophiuroids: Feeding mechanisms and life style Karin Boos Biologische Anstalt Helgoland/ Alfred Wegener Institut for Polar and Marine Research, PO Box 180, 27483 Helgoland; [email protected] Ophiuroid echinoderms are highly specific towards different habitats reflecting lifestyles and feeding mechanisms. Previous studies have considered ophiuroids to be generally omnivorous macro- or microphageous feeders. According to their lifestyle, however, different feeding mechanisms may have evolved e.g. deposit feeding, filter feeding or predation. Most ophiuroids typically show more than one feeding mechanism along with their main feeding mode. In the present study, the morphology of teeth and associated papillae on individual jaw elements (see figure right) from ophiuroids performing different lifestyles (epibenthic, infaunal or epibenthic-cryptic) are compared and discussed in relation to reported feeding mechanisms and diets (for explanation on teeth and papillae see numbers in the pictures and adjacent text sections).

Energetic Costs of Loss and Regeneration of Arms in Stellate Echinoderms John M
Integrative and Comparative Biology Advance Access published May 6, 2010 Integrative and Comparative Biology, pp. 1–9 doi:10.1093/icb/icq027 SYMPOSIUM Energetic Costs of Loss and Regeneration of Arms in Stellate Echinoderms John M. Lawrence1 Department of Integrative Biology, University of South Florida, Tampa, FL 33620, USA Downloaded from From the symposium ‘‘Animal Regeneration: Integrating Development, Ecology and Evolution’’ presented at the annual meeting of the Society for Integrative and Comparative Biology, January 3–7, 2010, at Seattle, Washington. 1E-mail: [email protected] http://icb.oxfordjournals.org Synopsis Loss of arms has energetic consequences for stellate echinoderms (crinoids, ophiuroids, and asteroids). The energetic cost of losing an arm includes loss of investment, decrease in ability to obtain nutrients and allocation of nutrients to regeneration of the lost arms at a cost to other body compartments. The cost to other body compartments is low when food availability is very low or very high. The cost becomes apparent when food availability is sufficient to support production but not high enough that the cost of regeneration has no effect on production of other body compartments. Loss of investment is greater in asteroids than in crinoids and ophiuroids because of greater development of the body wall and presence of gonads and pyloric caeca in the arms. The cost of regeneration of organic matter in an arm can be estimated from the amount of organic matter present in intact arms and the cost of anabolism. Protein production is the primary cost of regeneration of an arm because of the high concentration of protein in the regenerated at Health Sci Ctr LibraryMDC 31 on May 9, 2010 arm and the high anabolic cost of protein production. -
An Approach to the Ecological Significance of Chemically Mediated Bioactivity in Mediterranean Benthic Communities
MARINE ECOLOGY PROGRESS SERIES Vol. 70: 175-188, 1991 Published February 28 Mar. Ecol. Prog. Ser. An approach to the ecological significance of chemically mediated bioactivity in Mediterranean benthic communities Centre d'Estudis Avanqats de Blanes (C.S.I.C.), Caml de Santa Bhrbara s/n, E-17300Blanes (Girona),Spain Roswell Park Cancer Institute, 666 Elm Street, Buffalo, New York 14263,USA 3Pharma Mar S.A.. Calle de la Calera sln, Tres Cantos, Madrid, Spain ABSTRACT: Possible ecological roles of antibacterial, antifungal, antiviral, cytotoxic and antimitotic activities found in western Mediterranean benthos were investigated, and relationships were sought between these activities and taxonomic groups, presence of fouling organisms, and community struc- ture. Cytotoxic and antimitotic activities are the most abundant, and are widespread in almost all the taxonomic groups studied. Porifera. Bryozoa and Tunicata contain the most biologically achve chemi- cals. Cytotoxic molecules are more frequently present in tunicates than in bryozoans. There is a close association between antirnitotic and cytotoxic, as well as between antibacterial and antifungal. activities. As antifouling defences, cytotoxic and antimitotic activities seem to be less effective than antibacterial and antifungal ones; the latter appear to function in a generalist antifouling mode. Chemically rich species are much more abundant in sciaphilic/cryptic habitats than in photophilic ones. INTRODUCTION lation between toxicity and latitude, while McCLintock (1987) subsequently found a higher percentage of The production of biologically active substances in active species in the Antarctic region than at lower benthic organisms has traditionally been related to latitudes. Some authors have reported that the number various aspects of their biology (Stoecker 1978, 1980, of active species is higher in cryptic environments than Bergquist 1979, Castiello et al.
