“…Liman and Sarıkum Lakes, located in Black Sea region, have been influenced mainly by rivers (e.g., Kızılırmak River), and floodwater, only a few marine taxa were observed in these lakes (Sıvacı et al, 2008;Soylu et al, 2011). Nevertheless, low salinity of the Black Sea is suitable for marine and marine-brackish species to establish a community (Baytut & Gönülol, 2016;Kaleli, Kulikovskiy & Solak, 2017). Diatom flora of the two Black Sea lagoons revealed that both lakes were influenced mostly by the freshwater inputs.…”

Coastal lakes are shallow lakes that have variable characteristics through fluctuations and marine winds. In this study, benthic diatom composition in the coastal lake of Iztuzu, Dalyan of Muğla was investigated from the material collected in 2011 and 2015. Little research has been done on coastal lakes and lagoon diatom flora in Turkey; this study contributes a total of 49 taxa identified to species level and 9 of the taxa for the first time recorded for diatom flora of Turkey. The most abundant taxa were; Cocconeis placentula Ehrenberg, Diploneis bombus (Ehrenberg) Ehrenberg, Mastogloia sp. and Chamaepinnularia alexandrowiczii Witkowski, Lange-Bertalot and Metzeltin. The results reveal a habitat-specific flora for Iztuzu Lake and give an aspect of understanding the marine-brackish distribution of diatoms in coastal lakes and lagoons. The results extend the knowledge of marine and brackish diatoms in Turkey and could provide data for similar lagoon and lakes which are under protection.

“…In the some studies, it is stated that C. cymbiformis var. nonpunctata (Figure 3, m) was previously found by Şahin (1998), Sıvacı and Pabuçcu (2007), Baytut and Gönülol (2016). However, none of the previous studies are on sediment cores and in none of them has been found in fossil records.…”

The majority of phycological studies in Turkey focus on seasonal changes of phytoplankton and phytobenthos in lentic and lotic systems, while very few studies related to counting diatoms in sediment cores obtained as a result of paleolimnological work have been published. In this paleolimlogical study, seventeen (14+3) n e w diatom records for freshwater algal flora of Turkey were determined on sediment core samples at five different locations collected in July 2006 from Lakes Ladik (Samsun) and Hazar (Elazığ). We recorded seventeen diatom taxa belonging to Naviculales (8), Cymbellales (2), Eunotiales (2), Bacillariales (2), Fragilariales (1), Tabellariales (1) and Aulacoseirales (1) orders from Lakes Ladik (Samsun) and Hazar (Elazığ). All of the reported taxa are new records for freshwater algal flora of Turkey. General information on the morphology and taxonomy of the species are briefly described in this paper, with their illustrations.

“…In many coastal marine environments mixotrophic cryptophytes (Plagioselmis, Teleaulax, Rhodomonas and Cryptomonas) are part of key components of phytoplankton communities (Cloern & Dufford, 2005;Han & Furuya, 2000). In the Black Sea, only few studies have reported the distribution of cryptophytes in the coastal regions under the influence of Danube (Eker-Develi et al, 2012) and the Kızılırmak River (Baytut & Gonulol, 2016). However, the role of nutritionally rich cryptophytes with the highest organic content per cell volume among microalgae (Moal, Martin-Jezequel, Harris, Samain & Poulet, 1987) is apparently underestimated by cell volume to carbon conversion factors usually used for microalgae groups (Menden-Deuer & Lessard, 2000;Montagnes, Berges, Harrison & Taylor, 1994;Verity et al, 1992).…”

Feeding of non-indigenous cyclopoid copepod Oithona davisae in natural coastal phytoplankton assemblages from the Sevastopol Bay, the Black Sea, in late July and in late November 2013 and in artificial phytoplankton assemblage (mixture of 5 cultured microalgae) have been studied in laboratory experiments using flow cytometry. Three distinct main clusters of phytoplankton (2 μm < ESD < 20 μm) were identified in the natural water samples in both sampling period: photosynthetic picoeukaryotes, nanophytoplankton and nanoplanktonic cryptomonads (NanoPE). Female O. davisae grazed on all 3 phytoplankton groups but the highest ingestion rate in terms of carbon was on NanoPE with the value of 0.29±0.03 μg Cprey cop-1 d-1 in July. Low abundance of 3 phytoplankton groups in late November resulted in a very low but significant carbon ingestion on cryptophytes (0.008±0.002 μg Cprey cop-1 d-1) than on the other groups. Clearance rates and electivity indices confirmed positive selection only for cryptophytes from natural phytoplankton assemblages, and for cryptophyte strain IBSSCr54 and Tetraselmis suecica from artificial plurialgal mixture. Highest daily specific carbon-rations of O. davisae females were found on cryptophytes (ESD 7 -12 μm): up to 135% and 184% body carbon d-1 in late July and on artificial phytoplankton assemblage, respectively.
