EIFAC Occasional Paper No.44. Rome, FAO. 2010, 275 pp. ABSTRACT The symposium on Interactions between Social, Economic and Ecological Objectives of Inland Commercial and Recreational Fisheries and Aquaculture, was organized in conjunction with the Twenty-Fifth Session of the European Inland Fisheries Advisory Commission (EIFAC) in Antalya, Turkey, from 21 to 24 May 2008. The symposium objectives were: 1) To review the wide range of socio-economic and ecological interactions between fisheries and aquaculture and the roles of various stakeholders with respect to these interactions. 2) To identify where future research should focus and propose measures to decrease interactions that compromise sustainable development and management, and promote interactions that contribute to sustainability. 3) To provide information to policy and decision makers to contribute to the general awareness of trends in socio-economic and ecological interactions within and between the sector and other rural sectors. 4) To facilitate dialogue between scientists, researchers, fisherfolk, aquaculturists and policy and decision makers on the motives, interactions and interests of stakeholders. 5) To advise EIFAC on appropriate management and development measures and tools for inland fisheries and aquaculture in Europe. This Occasional Paper in conjunction with a special issue of Fisheries Management and Ecology represents the proceedings of the symposium. The symposium made considerable progress towards understanding the interactions between ecological/environmental and socio-economic/governance objectives for fisheries and aquaculture. There was a broad recognition that inland fisheries and aquaculture need to shift from a sectoral view where they are treated in isolation to an integrated, multi- disciplinary systems view.

ABSTRACT Lake Uluabat, having an international significance and subject to the Ramsar Convention, is fed by the basin of Musta- fakemalpaşa Stream which runs through fertile lands utilized for livestock breeding and agriculture. In this study, total amount of nitrogen (TN) and phosphorus (TP) loads of non-point pollutants (agriculture, livestock breeding, vegetation, surface runoff and small settlements) was calculated. It was found out that most intensive pollution load stemmed from livestock breeding which causes dispersion of 13653.57 tons·year−1 of TN and 3224.45 tons·year−1 of TP into the Lake Uluabat. Additionally, seasonal changes in concentration of TN and TP were observed during the period of 2008-2009 in Lake Uluabat. It was concluded that the rise of agricultural activities in summer months was the reason underlying the increase in pollution during the months in question.

Munis Entomology & Zoology, 5 (2): 380-498] ABSTRACT: All taxa of the tribe Dorcadiini Latreille, 1825 in Turkey are evaluated and summarized with zoogeographical remarks. Also Dorcadion praetermissum mikhaili ssp. n. is described in the text. KEY WORDS: Dorcadion, Neodorcadion, Dorcadiini, Lamiinae, Cerambycidae, Coleoptera, Turkey. The main aim of this work is to clarify current status of the tribe Dorcadiini in Turkey. The work on Turkish Dorcadiini means to realize a study on about one third or one fourth of Turkish Cerambycidae fauna. As the same way, Turkish Dorcadiini is almost one second or one third of Dorcadiini in the whole world fauna. Turkish Dorcadiini is a very important group. This importance originated from their high endemism rate, and also their number of species. However, the information on all Turkish Dorcadiini is not enough. The first large work on Dorcadiini species was carried out by Ganglbauer (1884). He evaluated a total of 152 species of the genus Dorcadion and 13 species of the genus Neodorcadion. He gave 30 Dorcadion species and 4 Neodorcadion species for Turkey. Then, the number of Turkish Dorcadion species raised to 53 with 23 described species by Heyden (1894), Ganglbauer (1897), Jakovlev (1899), Daniel (1900, 1901), Pic (1895, 1900, 1901, 1902, 1905, 1931), Suvorov (1915), Plavilstshikov (1958).

  • A Critical Review of the Anatolian Geology: a Dialectic to Sutures and Evolution of the Anatolian Tethys and Neotethys
    Mineral Res. Exp., Bull., 133, 1-29, 2006 A CRITICAL REVIEW OF THE ANATOLIAN GEOLOGY: A DIALECTIC TO SUTURES AND EVOLUTION OF THE ANATOLIAN TETHYS AND NEOTETHYS Metin ÞENGÜN* ABSTRACT.- A progressively improving hypothesis of evolution for the Anatolian Tethys and Neotethys will be presented in this paper. The Tethyan, the Western (Bursa-Ýzmir-Antalya zone) and the southern Neotethyan sutures will be substantiated after a discussion on the controversial aspects of the Anatolian geology. The initia- tion of the Tethys in Cambrian is supported on the basis of continous Palaeozoic sedimentation on north-facing Gondwanian and south-facing Eurasian platforms. A thin continental sliver, the Apula-Anatolia, started to rift off northern Gondwana in the Early Triassic coevally with the onset of the northward Tethyan subduction. The mar- ginal ophiolites have obducted onto the Pontian active margin by the Middle Triassic as the consequence of the dextral rotation of Western Pontides. The compressional and dilatational fields have shifted oceanward due to a recess (?) of the subduction zone. The positive area covering most of the central and northern Sakarya has col- lapsed progressively and has been onlapped peripherically from the Liassic onwards. The Anatolian microconti- nent detached off Africa in the Upper Triassic-Liassic and drifted northward during the Jurassic and the Cretaceous and collided incipiently with the Eurasian margin (Pontides) in the Upper Cretaceous. Unsubducted pockets of ocean floor have closed with consequent syn-collisional magmas in the Paleogene. The Salt Lake pocket, the East Anatolia and the Western Neotethys, the Intra-Gondwanian rift separating the Anatolia from Apulia-Greece, have survived until the Late Miocene.

Due to concerns about potential pollution resulting from watershed sources and adjacent agricultural lands, a study of the trophic state of lake Uluabat was conducted during the period February 2003 to January 2004. Total nitrogen (TN), total phosphorus (TP), Secchi disc depth (SD) and chlorophyll a (Chly a) were analyzed monthly in order to assess the trophic state of the lake. According to calculated nutrient ratios, phosphorus was found to be the primary limiting nutrient in lake Uluabat. Carlson’s trophic state index values, based on TP, SD and Chl a, indicated that lake Uluabat is an eutrophic system.
