ORCID-iD: https://orcid.org/0000-0001-9900-7277 Summary: Gorgonian species play an important ecological role in the structure and function of marine communities. Human activities are negatively affecting the conservation status of gorgonian populations in the Mediterranean. Acquiring knowl - edge of gorgonian distribution is therefore a key step required to promote efficient management and conservation actions. However, information on the distribution of gorgonian species is lacking in many Mediterranean areas. This study aimed to provide an overview of the geographic and bathymetric distributions of gorgonians in the coastal waters of the Tunisian coast (1136 km). The sampling design encompassed three sectors, 27 localities and 87 sites. Information was collected from scuba diving (26 sites) and local ecological knowledge surveys of fishermen and divers (132 interviews), as well as from a litera - ture review. Overall, the occurrence of eight gorgonians was confirmed at 54 out of the 87 sites surveyed in Tunisian coastal waters (7-120 m depth). The species that were found were Eunicella singularis, Eunicella cavolini, Paramuricea clavata, Paramuricea macrospina, Leptogorgia sarmentosa, Eunicella verrucosa, Corallium rubrum and Ellisella paraplexauroides . The highest gorgonian species richness and abundance was recorded in northern, followed by eastern Tunisian waters. In the southern areas only one species was recorded. This pattern was related to the rocky substrate that characterizes the northern and eastern coasts of Tunisia. This study is the first to report the occurrence of E. singularis, E. cavolini, E. verrucosa and Leptogorgia sarmentosa in northern and eastern Tunisian waters. The results are discussed in the hope of guiding future conservation and management actions for gorgonian assemblages in Tunisia. Keywords: sea fans; coralligenous; octocorals; scientific diving; Tunisia; local ecological knowledge; conservation. Distribución de las especies de gorgonias en las aguas costeras marinas de Túnez (Mediterráneo Central) Resumen: Las especies de gorgonias juegan un papel ecológico importante en la estructura y función de las comunidades marinas. Las perturbaciones asociadas a las actividades humanas están afectando negativamente el estado de conservación de las poblaciones de gorgonias en el Mediterráneo. Conocer la distribución de las especies de gorgonias es una etapa clave para promover planes de gestión y acciones de conservación eficaces. Sin embargo, en muchas áreas del Mediterráneo no disponemos de información sobre la distribución de las especies de gorgonias. Este estudio tiene como objetivo proporcionar una visión general de la distribución geográfica y batimétrica de las especies de gorgonias en las costas de Túnez (1136 km). El diseño del muestreo abarcó 3 sectores, 27 localidades y 87 estaciones de muestreo. Se recolectó información a través de muestreos con escafandra autónoma (26 estaciones), entrevistas a pescadores y buceadores (132 entrevistas) aplicando las técnicas de Local Ecological Knowledge (LEK), así como de una revisión de la literatura disponible. En general, la presen - cia de ocho gorgonias se confirmó en 54 de las 87 estaciones de muestreo en la costa de Túnez (7-120 m de profundidad). Las especies encontradas fueron Eunicella singularis, Eunicella cavolini, Paramuricea clavata, Paramuricea macrospina, Leptogorgia sarmentosa, Eunicella verrucosa, Corallium rubrum y Ellisella paraplexauroides . La riqueza y abundancia de especies de gorgonias fueron más elevadas en la costa del Norte de Túnez seguida por la costa Este. En la costa del Sur solo se encontró una única especie de gorgonia. Este resultado se ha relacionado con la mayor proporción de sustrato rocoso presente a las costas del norte y este de Túnez. Este estudio permitió citar la presencia por primera vez de las especies de gorgonias Eunicella singularis, E. cavolini, E. verrucosa y Leptogorgia sarmentosa en la costa del norte y este de Túnez. Los resultados obtenidos pretenden contribuir a la adopción de acciones de gestión y conservación de las poblaciones de gorgonias en Túnez. Palabras clave: gorgonias; coralígeno; octocorales; buceo científico; Túnez; conocimiento ecológico local; conservación.

  • Octocoral Diversity of Balıkçı Island, the Marmara Sea
    J. Black Sea/Mediterranean Environment Vol. 19, No. 1: 46-57 (2013) RESEARCH ARTICLE Octocoral diversity of Balıkçı Island, the Marmara Sea Eda Nur Topçu1,2*, Bayram Öztürk1,2 1Faculty of Fisheries, Istanbul University, Ordu St., No. 200, 34470, Laleli, Istanbul, TURKEY 2Turkish Marine Research Foundation (TUDAV), P.O. Box: 10, Beykoz, Istanbul, TURKEY *Corresponding author: [email protected] Abstract We investigated the octocoral diversity of Balıkçı Island in the Marmara Sea. Three sites were sampled by diving, from 20 to 45 m deep. Nine species were found, two of which are first records for Turkish fauna: Alcyonium coralloides and Paralcyonium spinulosum. Scientific identification of Alcyonium acaule in the Turkish seas was also done for the first time in this study. Key words: Octocoral, soft coral, gorgonian, diversity, Marmara Sea. Introduction The Marmara Sea is a semi-enclosed sea connecting the Black Sea to the Aegean Sea via the Turkish Straits System, with peculiar oceanographic, ecological and geomorphologic characteristics (Öztürk and Öztürk 1996). The benthic fauna consists of Black Sea species until approximately 20 meters around the Prince Islands area, where Mediterranean species take over due to the two layer stratification in the Marmara Sea. The Sea of Marmara, together with the straits of Istanbul and Çanakkale, serves as an ecological barrier, a biological corridor and an acclimatization zone for the biota of Mediterranean and Black Seas (Öztürk and Öztürk 1996). The Islands in the Sea of Marmara constitute habitats particularly for hard bottom communities of Mediterranean origin. Ten Octocoral species were reported by Demir (1954) from the Marmara Sea but amongst them, Gorgonia flabellum was probably reported by mistake and 46 should not be considered as a valid record from the Sea of Marmara.

  • Deep‐Sea Coral Taxa in the U.S. Gulf of Mexico: Depth and Geographical Distribution
    Deep‐Sea Coral Taxa in the U.S. Gulf of Mexico: Depth and Geographical Distribution by Peter J. Etnoyer1 and Stephen D. Cairns2 1. NOAA Center for Coastal Monitoring and Assessment, National Centers for Coastal Ocean Science, Charleston, SC 2. National Museum of Natural History, Smithsonian Institution, Washington, DC This annex to the U.S. Gulf of Mexico chapter in “The State of Deep‐Sea Coral Ecosystems of the United States” provides a list of deep‐sea coral taxa in the Phylum Cnidaria, Classes Anthozoa and Hydrozoa, known to occur in the waters of the Gulf of Mexico (Figure 1). Deep‐sea corals are defined as azooxanthellate, heterotrophic coral species occurring in waters 50 m deep or more. Details are provided on the vertical and geographic extent of each species (Table 1). This list is adapted from species lists presented in ʺBiodiversity of the Gulf of Mexicoʺ (Felder & Camp 2009), which inventoried species found throughout the entire Gulf of Mexico including areas outside U.S. waters. Taxonomic names are generally those currently accepted in the World Register of Marine Species (WoRMS), and are arranged by order, and alphabetically within order by suborder (if applicable), family, genus, and species. Data sources (references) listed are those principally used to establish geographic and depth distribution. Only those species found within the U.S. Gulf of Mexico Exclusive Economic Zone are presented here. Information from recent studies that have expanded the known range of species into the U.S. Gulf of Mexico have been included. The total number of species of deep‐sea corals documented for the U.S.

This species, currently protected in Spain, is present as isolated colonies or as a low number of them, except in the Chafarinas Islands, where higher densities can be found below a depth of 20 m. Nevertheless, as revealed by a previous study, a great number of colonies are partially covered by epibionts or totally dead. As a first objective of the present work, seven transects were performed in 2013 and 2014 to evaluate the percentage of colonies affected in areas that had not been previously sampled. Approximately between 35% and 95% of the colonies had different degrees of epibiosis or were dead. In 2015, ten transects were performed to specifically locate young colonies smaller than 15 cm, which could be indicative of popula- tion regeneration by sexual reproduction.
