Sampling was performed in cold and warm seasons of 2013–2020, from stations located on the three sectors of the Romanian Black Sea coast (northern-N, central-C, and southern-S). After determining the species composition, abundance, and biomass, the results were subjected to statistical analysis. A total of 25 taxa were identified, Copepoda representing the bulk of the community. The analysis of the main components explains, through the first two identified factors—temperature and salinity, the variation of environmental factors. The mesozooplanktonic community responded differently to the analysed environmental factors, recording positive and negative correlations, depending on the water column’s depth; a positive correlation was observed between mesozooplank-ton and temperature while negative correlations were observed between nutrients (silicon) and mesozooplankton.","PeriodicalId":49407,"journal":{"name":"Turkish Journal of Zoology","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48092573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The abundance of A. kagoshimensis , which is not subjected to commercial fishing, is important in terms of food competition with other bivalvia species. Baby clam ( Chamelea gallina ) together with the A. kagoshimensis are dominant bivalve species found in the sandy and muddy areas off the coastal waters of the Black Sea. In this study, specimens of A. kagoshimensis have been recognized by morphological analysis and also confirmed by molecular characterization. Furthermore, the abundance and growth parameters of A. kagoshimensis were investigated in the Southwestern Black Sea. Blood cockles were sampled between February 2011 and December 2012, seasonally. According to the Von Bertalanffy Growth Parameters (VBGP) the results were L ∞ = 81.96 mm, K = 0.32 year –1 , t 0 = –0.22 year, and nonseasonal L ∞ = 84.32 mm, K = 0.31 year –1 , t 0 = –0.21, WP = 0.65, t s = 0.15. The growth pattern showed the slope [b] = 2.96–3.01 in 2011 and 2012. The stock size was estimated according to two different years in 5 different subareas (Cide, İnebolu, Türkeli, Ayancık, and Sarıkum) and by 4 different strata (0–5 m, 5–10 m, 10–15 m, and 15–20 m). Considering subareas, the A. kagoshimensis population in all subareas increased significantly in a single year. Compared to other regions, İnebolu was the main highly distributed area of the A. kagoshimensis , and also the estimated stock size was the highest in the region. Due to food competition with other commercial species (mainly Chamelea gallina ) A. kagoshimensis is an ecology important species for the Southern Black Sea habitats. It is aimed to make contributions to Good Environmental Status (GES) and fisheries management in the region.","PeriodicalId":49407,"journal":{"name":"Turkish Journal of Zoology","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48594192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, 16 morphometric variables of the sagittal otolith, including six morphometric characters, six shape indices, and four ecomorphological indexes, were investigated for the first time among P. acarne stocks collected from the Aegean and Marmara Seas coasts of Turkey. Statistically significant differences were found between the right and left otolith variables of P. acarne individuals in both stocks (p < 0.05). Similarly, significant differences were observed on the same side between stocks (p < 0.05). The right otoliths exhibited higher discrimination power than the left within the two stocks. The PCA showed that only five (31.25%) (otolith area, otolith perimeter, form factor, roundness, and edge complexity index) out of the sixteen variables were quite important characters in the differentiation between stocks. These otolith characters demonstrated a very high rate of accurate discrimination (99.0%) between stocks. The results indicated otolith morphometric characters, shape indices, and ecomorphological indexes can be used as suitable tools to discriminate P. acarne stocks. This is the first study to include all otolith characters such as morphometrics, shape, and ecomorphological indices that discriminate between P. acarne stocks from these localities.","PeriodicalId":49407,"journal":{"name":"Turkish Journal of Zoology","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48401860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In total, 34 species belonging to 19 families were sampled. Approximately 70% of the total fish abundance were Atherina boyeri Risso, 1810 , Chelon auratus (Risso, 1810) and Chelon saliens (Risso, 1810). Highest abundance was detected from S5 (Marmara Ereğlisi) and S11 (Florya) comprising 17.3% and 14.2% of total abundance, respectively. Maximum species richness was found at S4 (Erdek) and S12 (Yalova Tigem), with 21 and 18 species, respectively. The highest biodiversity indexes were seen at S4, S8 (Karacabey floodplain area) and S12, whereas the lowest biodiversity index was found at S9 (Büyükçekmece). S4 and S8 should be monitored and protected by fisheries management authorities due to being nursery and protection areas for the Sea of Marmara.

Results showed that Culiseta longiareolata and Culex quinquefacsiatus were constant, Culex destricola, Culex pusillus, Culex pipiens and Culex laticinctus were common and the other captured species were accidental species in Sirjan County. In this study, Aedes vittatus was recorded for the first time in Kerman Province.

The main objective of this research is to examine the mean abundance, prevalence, and diversity of ornithophilic louse flies in Serbia. They have been detected through visual inspection or fumigation of caught birds. In total, 79 louse flies belonging to four genera and six species were collected from 62 individuals within 26 host species. A single louse fly infested the bulk of captured birds, while hippoboscid females were statistically dominant within the overall sample. Most detected louse flies belonged to the genus Ornithomya , with Ornithomya avicularia and Ornithomya fringillina being the most abundant at the species level. The prevalence was relatively low, along with the mean intensity and abundance. This study contributes to a better understanding of louse flies and their parasite-host associations in Serbia. It also fills a gap in the knowledge of their diversity and distribution in South-eastern Europe.","PeriodicalId":49407,"journal":{"name":"Turkish Journal of Zoology","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49515725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
