Akdeniz Bölgesinin Sıcak Koşullarında Yabancı İstilacı Deniz Türleri (Fethiye-Göcek ÖÇKB, Muğla, Türkiye)

Öz

Bu çalışma, Fethiye-Göcek ÖÇKB'de (Muğla, Türkiye) tespit edilen sekiz yabancı deniz türü (YDA) hakkında bilgi vermekte ve güncellenmiş bir incelemeyi tanımlamaktadır. Cheilodipterus novemstriatus, yosun örtülerinde yoğun olarak otlayan büyük topluluklarda tespit edilen Diadema setosum ile birlikte gözlenmektedir. Bazı alanlarda, özellikle Güney Ege ve Akdeniz kıyılarında Synaptula reciprocans, Pterois miles ve Torquigener flavimaculosus kaydedilmiştir. Kuzey Ege Denizi'ne doğru önemli bir yayılım gösteren Ganonema farinosum ve Caulerpa taxifolia var. distichophylla ve C. racemosa f. requienii belgelenmiştir. C. taxifolia var. distichophylla dışında, bu biyolojik istilaların ana vektörü koridordur (Süveyş Kanalı) ve kökenleri Kızıldeniz'dir. Akdeniz'deki kıyı biyoçeşitliliği için başlıca tehdit olarak kabul edilen NIS, AB Deniz Stratejisi Çerçeve Direktifi, 2017'ye göre ekolojik durumun temel göstergelerinden biri olmuştur. Bu nedenle, Türkiye kıyılarından bölgesel veri setleri oluşturularak, mevcut çalışma, düzenleyici, muhafazakar ve yönetimsel amaçlar için MSFD, 2017'nin uygulanmasına katkıda bulunacaktır.

Alien-Invasive Marine Species in Warmer Conditions of a Mediterranean Region (Fethiye-Göcek SEPA, Muğla, Türkiye)

Öz

This paper reveals information and describes an updated review on eight non-indigenous marine species (NIS) detected in Fethiye-Göcek SEPA (Muğla, Türkiye). Cheilodipterus novemstriatus is observed with Dia-dema setosum that has been detected in large communities grazing intensively on algal canopies. In some si-tes, Synaptula reciprocans, Pterois miles and Torquigener flavimaculosus, mainly along the South Aegean and Mediterranean coasts, are recorded. Ganonema farinosum and Caulerpa taxifolia var. distichophylla and C. racemosa f. requienii with a significant spread towards the northern Aegean Sea, are documentated. Except for C. taxifolia var. distichophylla, the main vector of these bioinvasions, is the corridor (Suez Canal) and their origin is the Red Sea. Regarded as a main threat to the coastal biodiversity in the Mediterranean, NIS have been one of the main indicators of ecological status in accordance with the EU Marine Strategy Fra-mework Directive, 2017. Therefore, constructing regional datasets from the Turkish coasts, the current work will contribute to the implementations of MSFD, 2017 for the regulatory, conservative and management pur-poses.
