  • aegean Territorial Waters conflict an evolutionary narrative
    Conflict Management and Peace Science, 2004
    Co-Authors: Serdar Guner
    Abstract:

    Delimitation of the Territorial Waters and continental shelf in the Aegean Sea constitutes a constant source of conflict and produces recurrent crises between Greece and Turkey. This article explores directions that the Greek–Turkish dispute over the delimitation of Territorial Waters can take through an evolutionary game framework. Crises are found to follow routines and practices involving challenges to the status quo and reactions preceding mutual retreat. Hence, the status quo in the Aegean Sea can persist even in the form of aggressive behavior. It is also possible that the dispute will evolve into a stable state of conflict where no cooperative foreign policy can survive.

  • aegean Territorial Waters conflict an evolutionary narrative
    Social Science Research Network, 2003
    Co-Authors: Serdar Guner
    Abstract:

    Conflicts over the delimitation of Territorial Waters are abundant around the globe. Greece and Turkey, two NATO allies, are no exceptions. The delimitation of Territorial Waters and continental shelf, the status of islands, islets, and flight control zones and corridors in the Aegean Sea constitute constant sources of friction between them. We offer an evolutionary game model to explore for directions their relations can take including chances of new crises and the revision of the status quo. We find that crises constitute a norm in bilateral relations of the two littoral states. The crisis equilibrium indicates routinized practices involving first displaying then falling back. Hence aggressive behavior can be periodically observed but the current status quo will persist. A revised status quo becomes a likely prospect only if both countries were posited as single unitary actors maximizing their expected utilities.

  • seagrass mapping in greek Territorial Waters using landsat 8 satellite images
    International Journal of Applied Earth Observation and Geoinformation, 2018
    Co-Authors: Konstantinos Topouzelis, Despina Makri, Nikolaos Stoupas, Apostolos Papakonstantinou, Stelios Katsanevakis
    Abstract:

    Abstract Seagrass meadows are among the most valuable coastal ecosystems on earth due to their structural and functional roles in the coastal environment. This study demonstrates remote sensing’s capacity to produce seagrass distribution maps on a regional scale. The seagrass coverage maps provided here describe and quantify for the first time the extent and the spatial distribution of seagrass meadows in Greek Waters. This information is needed for identifying priority conservation sites and to help coastal ecosystem managers and stakeholders to develop conservation strategies and design a resilient network of protected marine areas. The results were based on an object-based image analysis of 50 Landsat-8 satellite images. The time window of image acquisition was between June 2013 and July 2015. In total, the seagrass coverage in Greek Waters was estimated at 2619 km2. The largest coverages of individual seagrass meadows were found around Lemnos Island (124 km2), Corfu Island (46 km2), and East Peloponnese (47 km2). The accuracy assessment of the detected areas was based on 62 Natura 2000 sites, for which habitat maps were available. The mean total accuracy for all 62 sites was estimated at 76.3%.

  • COMMUNITY STRUCTURE ECHINODERMS (ASTEROIDEA, OPHIUROIDEA, ECHINOIDEA AND HOLOTHUROIDEA) IN THE MARINE NATIONAL PARK EAST SULAWESI WAKATOBI
    Jurnal Ilmu dan Teknologi Kelautan Tropis, 2016
    Co-Authors: Eddy Yusron
    Abstract:

    A study on Echinoderms community structure in marine national parks of Wakatobi, Southeast Sulawesi was conducted in six locations, i.e., Waha Beach, Coastal Sombo, Beach Houses, Beach Kapota, Banakawa beach, and Umala beach in October 2013. All of the six parks were located the Wakatobi Territorial Waters with coordinates of 5°06'25" S and 12 3 °124'10 E. The results showed of 18 species of echinoderms representing six different types of Asteroidea, two types of Ophiuroidea, six types of Echinoidea, and four types of Holothuroidea. Group of starfish or Asteroidea was the most prominent on seagrass area. Based on the six transects sites, it turned out that the group of starfish (Asteridea) occupied a relatively high level of species richness. From the quantitative analysis values, we obtained diversity index (H) of 1.105 in Sombu, the highest evenness index (J) of 0.989 was found in Umala, and the highest species richness index values (D) of 0.132 was obtained in kapota. It seemed that all echinoderm groups were generally like seagrass microhabitat (12 types). While, sand and dead coral habitats were only occupied by 8 (eight) echinoderm groups.

  • first records of the indo pacific finless porpoise neophocaena phocaenoides g cuvier 1829 cetartiodactyla phocoenidae from sri lanka
    Journal of Threatened Taxa, 2017
    Co-Authors: Ravi Prabath Nanayakkara, Thomas A. Jefferson, Sandaruwan Abayaratne
    Abstract:

    Thirty species of marine mammals have been recorded from Sri Lanka. Amongst them the Indo-Pacific Finless Porpoise Neophocaena phocaenoides is the only representative of the family Phocoenidae . The only previous record from Sri Lanka was a specimen caught on the Wadge Bank by a Smithsonian Carangid Survey team in 1970. Wadge Bank is west of the island and is, in fact, in Indian Territorial Waters. Here we present the first legitimate records of the Finless Porpoise from Sri Lanka, based on one stranding and three live sightings. Furthermore, the occurrence of threatened species such as the Indo-Pacific Finless Porpoise in the Waters of the Palk Bay and the Gulf of Mannar indicates that a cross boundary research initiative between Indian and Sri Lankan scientists, simultaneously focusing on the conservation of the species, is essential. We believe, through such an initiative, a more holistic approach could be adopted when studying and conserving the species, which could then be expanded to encapsulate many other marine species and ecosystems.

  • parasites from indo pacific hump backed dolphins sousa chinensis and finless porpoises neophocaena phocaenoides stranded in hong kong
    Veterinary Record, 2001
    Co-Authors: E C M Parsons, Robin M. Overstreet, Thomas A. Jefferson
    Abstract:

    Between 1993 and 1998,28 Indo-Pacific hump-backed dolphins ( Sousa chinensis ) and 32 finless porpoises ( Neophocaena phocaenoides ) stranded in Hong Kong Territorial Waters were examined postmortem for parasites. The nematode Halocercus pingi was discovered in the lungs of one hump-backed dolphin and in 10 finless porpoises, typically within abscesses or granulomata, and they were frequently accompanied by a catarrhal exudate and lesions characteristic of pneumonia. Seven of the 10 finless porpoises were calves with substantial lungworm infections, and three were neonates with visible fetal folds and umbilical remnants, suggesting that H pingi is transferred to the neonate before birth or during lactation. Electron micrographs of Hpingi should allow the nematode to be identified by other researchers. An ectoparasitic stalked barnacle ( Xenobalanus globicipitis ) was recovered from a finless porpoise, the first time that this species of bamacle has been recorded in Hong Kong9s Territorial Waters.
