Results showed a more`mature' community in 1995^1997 with an increase in the number of species. After a short period, in spring 1995, during which the structure of the community was comparable to those described in 1972^1973, the assem- blage was characterized by a great inter-annual structural stability. Densities of dominant species seem to £uctuate around a mean value comparable to the carrying capacity of the biota for these species.The recruit- ment of the dominant species with a long life span appears low compared to the densities of adults but seems su¤cient to assure the replacement of individuals. Our results suggest that the pattern of massive recruitment followed by high mortality rates could not be the general rule and that a pattern of moderate recruitment followed by low post-settlement mortality of recruits should be more frequent.

Uzunova СПИСЪК НА МОРСКИТЕ АМФИПОДИ (CRUSTACEA, MALACOSTRACA) ОТ БЪЛГАРСКИЯ СЕКТОР НА ЧЕРНО МОРЕ С. Узунова Резюме : В настоящата публикация е обобщена наличната информация за морски видове от Разред Amphipoda (Crustacea, Malacostraca ) от българския сектор на Черно море . Съобщени са общо 55 вида морски амфиподи , принадлежащи към 26 семейства от разред Amphipoda. Ключови думи : Amphipoda, Crustacea, Black Sea, checklist . Introduction First information about Amphipoda from the Bulgarian Black Sea area is available in CHICHKOFF [9] and CASPERS [8]. VALKANOV [47] created the first catalogue of the Black Sea fauna from Bulgarian coastal area. Later on KUNEVA -ABADJIEVA [15] reported 46 amphipod species for the Bulgarian waters and the region of Bosphorus. In 1968 KUNEVA -ABADJIEVA [17] described for first time the species Cheirocratus sundevalli (RATHKE , 1843) for the Black Sea. VALKANOV &M ARINOV [44] added new 9 amphipod species. Several works on amphipod distribution and ecology were published by KUNEVA -ABADJIEVA [13, 14, 16, 18, 19], KUNEVA -ABADJIEVA & MARINOV [21,22], MARINOV & KUNEVA -ABADJIEVA [25], MARINOV et al. [26], MARINOV &S TOYKOV [27] and UZUNOVA [36,37,38,39]. MARINOV [23] summarized the number of amphipod species to 62, brackish water ones included. UZUNOVA [39] reported total of 46 species from the sublittoral and mediolitoral zone. More recent information about the distribution of amphipoda in the upper sublittoral and Zostera beds is found in UZUNOVA [40, 41]. The aim of the present paper is to update the information for the marine Amphipoda from the Bulgaria Black Sea area, according to the recent taxonomic advances.

    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.

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.

  • 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).

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.
