Seasonal variations in species composition and abundance of tintinnids were investigated in the eutrophic coastal and offshore waters of Mersin Bay. Twelve sampling cruises were performed from September 2008 to February 2011. A total of 85 tintinnid taxa were identified. Among the recorded genera, agglutinated Tintinnopsis had the largest number of species (12 species), followed by hyaline loricated Eutintinnius (9 species), and Proplectella (7 species). Stenosemella ventricosa, Tintinnopsis beroidea, T. compressa. Favella azorica. and Helicostemella subulata were the dominant species during the study period. There were clear seasonal variations in species composition and abundance of tintinnids. The highest number of tintinnid species occurred in January 2009 and November 2010 in the entire study area, while the lowest species number occurred in March 2009. Morever, species numbers were higher in offshore stations than coastal stations. Some species were present in the coastal area of the bay, and other species were present offshore. The highest tintinnid abundance values were found in September 2008 (820 ind l(-1)) and August 2009 (749 ind l(-1)) at coastal stations. The high abundance values in the coastal stations indicate that an increase of tintinnids is closely related to trophic status of the marine environment. In connection with these results, correlation analysis revealed that chlorophyll-a had an important effect on tintinnid abundance. Tintinnid communities may be used as a potential bio-indicator for assessing the trophic state of the coastal seas and bays.

Spatial and temporal variability in the chemical properties of the oxic and suboxic layers of the Black Sea Tuğrul, Süleyman; Murray, James W.; Friederich, Gernot E.; Salihoglu, Ilkay (Elsevier BV, 2014-07-01) The Black Sea, a land-locked deep basin with sulfide bearing waters below 150-200 m, has been subject to anthropogenic pressures since the 1970s. Large inputs of nutrients (nitrate - N, phosphate - P, silicate - Si) with high N/P but low Si/N ratios and subsequent development of intensive eutrophication over the basin have changed vertical distributions and inventories of nutrients and redox-sensitive metals in the oxic, suboxic and anoxic layers. Chemical data sets obtained between 1988 and 2010, and older...
Genetic and morphologic diversity of Pseudophoxinus (Cyprinidae): implication for conservation in Anatolia TELLİ, MURAT; Aykut, Kence (Springer Science and Business Media LLC, 2015-01-01) Pseudophoxinus a freshwater fish genus shows remarkable diversification with high number of endemic species in Anatolia. Most of the species of the genus are categorized as endangered for conservation in IUCN Red List due to water abstraction and habitat destruction. The aim of the study is to investigate genetic and morphological structure of Pseudophoxinus populations using allozyme, microsatellite markers and geometric morphometrics (eight landmarks). Sample collection was performed from eight localities...
Patterns of dark respiration in aquatic systems Mantikci, Mustafa; Staehr, Peter A.; Hansen, Jorgen L. S.; Markager, Stiig (CSIRO Publishing, 2020-01-01) We used continuous measurements of dissolved oxygen (DO) in dark bottles to characterise patterns of the dark respiration rate (R-dark) for three marine phytoplankton monocultures and in natural-water samples from two marine coastal systems. Furthermore, patterns of ecosystem community respiration rate were determined from open-water changes in DO in a fjord and in a lake. We considered two models of R-dark to describe temporal changes in DO: constant R-dark and decreasing R-dark; increasing R-dark. In addi...
Distribution and abundance of ctenophores, and their zooplankton food in the Black Sea. I. Pleurobrachia pileus Mutlu, E; Bingel, F (Springer Science and Business Media LLC, 1999-12-01) The distribution of Pleurobrachia pileus Muller, 1776 in the Black Sea was determined using plankton samples collected above the anoxic zone (maximum of 200 m) in the winter, spring, and summer of 1991 to 1995; The summer samples were collected in 1991 to 1993 (for a previous) and are included in this paper for comparative purposes. High concentrations of P. pileus were found at the northern edges of anticyclonic eddies along the southern coastal regions. The biomass and abundance of P. pileus increased fro...
Satellite-detected early summer coccolithophore blooms and their interannual variability in the Black Sea Cokacar, T; Oguz, T; Kubilay, N (Elsevier BV, 2004-08-01) Interannual variability of the prevalent early summer coccolithophore blooms within surface waters of the Black Sea was studied by means of satellite-based bio-optical observations. Two coccolith detection algorithms, tested for the Black Sea conditions, were found to provide comparable spatial coccolith patterns consistent with the corresponding true color images. Reliability of the algorithms is also supported by several sets of time-series measurements in different parts of the basin. An analysis of 6 ye...
