Abstract

Marsupenaeus japonicus (Bate, 1888) is one of the alien species in the Mediterranean Sea introduced from the Indo-Pacific through the Suez Canal. The present study reports this species for the first time from the Turkish part of the Black Sea. This species was intentionally introduced to the Sea of Marmara in the 1960’s. It is assumed that the species was possibly introduced through the Istanbul Strait to the Black Sea.

Abstract

Sabella pavonina Savigny, 1920 (Annelida, Sabellidae) was recorded for the first time in the pre-bosphoric region of the Black Sea in 2010. One specimen of this species was encountered among samples collected at 82 m depth during the cruise 15/1 of RV «Maria S. Merian» (Germany). The specimen found is morphologically similar to the deep-water populations of S. pavonina in the Mediterranean Sea.

Abstract

Synaptula reciprocans was reported in the Mediterranean Sea for the first time back in 1986. Since then there have been numerous reports, following the species’ gradual expansion and establishment in the eastern Mediterranean basin. Here we report, by using citizen science methods, from the project titled “Is it Alien to you? Share it” of iSea, the most recent known expansion sites of S. reciprocans, including its new northern-most frontier. Furthermore, the provided photographic evidence testifies for possible interspecies relationships, for the first time.

Abstract

The devil firefish, Pterois miles (Bennett, 1828), is an invasive venomous Lessepsian fish species with a wide distribution within tropical waters of the Indian and Atlantic Oceans. The first Mediterranean record of P. miles was reported from Haifa Bay in 1991 and 22 years later, two specimens were reported from the Lebanese coast. Even though this species is considered as rare in the Mediterranean Sea up to 2015, it was recorded with an increasing rate from the Mediterranean coast of Turkey recently. In this study, a review of the scientific reports is given in the Mediterranean Sea with the reports of P. miles sightings on electronic social media, which were photographed by local divers in the Turkish coast of the Mediterranean Sea. Date of sighting, locality, depth, water temperature and other information were also recorded. The aim of the present study is to compile information about the increasing occurrence of the species in the Turkish coasts of the Mediterranean Sea.

Abstract

Phenol pollution in the sediments of the eastern and western part of the Turkish Black Sea coasts was identified by GC/MS and determined by colorimetric methods. The phenol levels were found as 3.773 and 3.754 (µg/g) in the western part, 0.0334 (µg/g) in the eastern part. It is the first finding for phenol contamination in the sediments of the Turkish Black Sea coasts.

FIRST RECORD OF PACHYGRAPSUS MAURUS (LUCAS, 1846) IN THE NORTHERN TUNISIAN COAST

Abstract

The cryptogenic grapsid crab Pachygrapsus maurus (Lucas, 1846), is a native species in the Mediterranean Sea that has been reported since the 1990s in several parts of the central basin such as the Maltese islands and Italian coast. However, the species presence in the areas such as eastern Algeria, Tunisia and Libya has not been documented previously. In September 2016, a preliminary survey was carried out to investigate the marine biodiversity in the channel of Bizerte (Northern Tunisia), during which P. maurus was observed and documented. Individuals were captured, photographed and identified based on key morphological features. The number of individuals observed indicates the species is well-established within the specialized rock and boulder habitat with strong wave exposure preferred by this species.

Abstract

The encounter rate, relative abundance and distribution of bottlenose dolphins were investigated as part of a first detailed study on cetacean populations in the Greek North Aegean Sea. Sighting data were recorded between 2005 and 2013 through dedicated scientific marine surveys, covering 14,701 km. The line-transect sampling method was used to estimate relative abundance, using Distance software 6.0. Bottlenose dolphins presented an overall encounter rate of 0.46 groups/100km (2.5 dolphin/100km) and a mean group size of 3.45 (SE=0.38). The yearly relative abundance in the area was estimated after post-stratification at 377 individuals (95% C.I.=289–465; CV=18.37). Environmental modeling has been proposed for the main species of the study area using GAM and PCA; dolphin sightings were then correlated to eight environmental variables (distance from the coast, depth, slope, gradient of salinity, median salinity, gradient of temperature, median temperature and mean current). Bottlenose dolphin sightings were significantly correlated to depth and median temperature. This research presents the first data on encounter rate, relative abundance for the species and species distribution in relation to environmental variables in study area which are essential for effective conservation and management considerations.
