    Meiobenthic Assemblages from the Southwestern Coast of the Black Sea, Igneada (Turkey)
    (Springer, 2016) Urkmez, Derya; Sezgin, Murat; Karacuha, Melek Ersoy; Oksuz, Ibrahim
    Meiobenthic organisms were sampled for the first time from. Igneada coasts, Turkey (Western Black Sea) in order to provide a base-line study on the meiobenthic community structure of the sampling area. Meiobenthos was found to be composed of 12 higher taxonomical groups: Nematoda, Harpacticoida, Polychaeta, recent hard-shelled Foraminifera, soft-shelled Foraminifera, Bivalvia, Gastropoda, Ostracoda, Turbellaria, Oligochaeta, Nemertea and Acari. Meiobenthic community was dominated by nematodes, harpacticoid copepods and hard-shelled foraminifera in the study area. Fifty two species of Nematoda, fifteen species of Harpacticoida and twelve species of living hard-shelled Foraminifera were identified. Six nematode species (Bathylaimus australis, Bolbolaimus murinae, Neochromadora poecilosomoides, Neochromadora sabulicola, Oncholaimellus mediterraneus and Onyx perfectus) are reported for the first time from Turkey although they are known to occur at the central Turkish Black Sea. Total density of the meiobenthos ranged between 67-757 ind. 10 cm(-2) at stations. Nematodes showed densities ranging from 61 to 350 ind. 10 cm(-2) which represented 25-92% of the total meiobenthos. Since the terrestrial part of the region is protected as a National Park and the coastal part has been proposed as a marine protected area, research should be intensified on the fauna of. Igneada coastal waters to clarify the biodiversity of the area.

    The relationship between dietary habits of late adolescent individuals and the heavy metal accumulation in hair
    (Mattioli 1885, 2020) Gonener, Ahmet; Karacuha, Melek Ersoy; Cabar, H. Demet; Yilmaz, Muhitdin; Gonener, Utku
    Study Objectives: This study aimed to determine the effects of smoking status and dietary habits on heavy metal accumulation in late adolescent students studying at Sinop University. Methods: This experimental research was conducted between 09 October and 15 November 2019. The population of the study was composed of 18-21 age (late adolescent period) students studying at Sinop University, School of Health. In the determination of the research sample, the selection of students who accepted to participate in the research as the case selection criteria, who did not have any mental or chronic disease/syndrome, and who did not use drugs continuously was taken into consideration. For the collection of research data, an information form about the weekly consumption of foods and smoking status was prepared by the researchers considering the geographical and physical locations where the students are located. After collecting the forms filled by students, 0.5 g hair samples were taken from volunteered 41 students to analyze the concentration of heavy metal in the hair and analyzed in the ICP-MS device. The data were evaluated using the Mann-Whitney U test in the SPSS (version 22.0) statistical program. Results: As a result of this research, it has been revealed that there was a statistically significant relationship between some food groups (lettuce, chips, instant soup, salami, and trout) that students express at least once a week and the heavy metal concentration detected in their hair. Conclusion: It was revealed that there is a relationship between individuals' dietary habits and heavy metals in late adolescence.

    Within-year spatio-temporal variation in meiofaunal abundance and community structure, Sinop Bay, the Southern Black Sea
    (Walter De Gruyter Gmbh, 2016) Urkmez, Derya; Sezgin, Murat; Karacuha, Melek Ersoy; Oksuz, Ibrahim; Katagan, Tuncer; Bat, Levent; Dagli, Ertan
    The first comprehensive meiobenthos study was carried out in Turkey, the Southern Black Sea (Sinop) from August 2009 to July 2010. Sediment samples were collected monthly at eight stations at 3 m and 10 m water depths located on four transects. A metal push core sampler (surface area 12.56 cm(2) and length 10 cm) was used to obtain the material. Meiofaunal abundance and composition were examined. The results revealed that the meiofaunal community consists of twenty five higher taxonomic groups. Four groups dominated the community: Nematoda, Harpacticoida, Foraminifera and Polychaeta. Spatial and temporal meiofaunal abundance fluctuated among stations and over time.
