The aim of this research was to compare the phytoplankton structure on basis environmental variables and test Q assemblage index based functional groups in two shallow Mediterranean lakes [Lake Taşkısığı (LT) Lake Little Akgöl (LLA)] north Turkey. Variations parameters were analyzed monthly at stations each lake between January 2013 December 2013. We showed that total phosphorus (TP) values vital shaping biomass eutrophic LLA. Nitrate-nitrogen (NO3-N), TP, zmix/zeu, macrophyte coverage are...

Abstract Both phytoplankton of the Kizilirmak River/Black Sea transition zone and their interactions with nutrients were investigated between July 2007 December 2008. A total 447 taxa belonging to divisions: Cyanobacteria (24), Bacillariophyta (209), Bigyra (1), Cercozoa Charophyta (11), Chlorophyta (32), Cryptophyta Miozoa (119), Euglenozoa (14), Haptophyta (13), Ochrophyta (10) Protozoa Incertae Sedis (2) identified at 5 different sites in study area. Seventy four recognized as new records...

ABSTRACT The composition and seasonal variations of phytoplankton Lake Ladik were studied between June 2000 May 2001. taxa identified included members Cyanoprokaryota (8), Bacillariophyta (46), Chlorophyta (54), Euglenophyta (30), Cryptophyta (2), Dinophyta (1) Xanthophyta (1). In the phytoplankton, Cyclotella ocellata, Aulacoseria distans, Trachelomonas hispida, T. volvocina var. punctata, Cryptomonas ovata, Pediastrum spp., Scenedesmus spp. common organisms. Seasonal in appeared to be...

Functional classification and composition of phytoplankton Liman Lake were studied between January 2002 December 2003.A total 109 taxa belonging to Bacillariophyta, Chlorophyta, Cyanophyta, Dinophyta, Xantophyta, Chrysophyta Cryptophyta identified.The succession during began with R-Strategists (with a high surface volume ratio, including blue-green algae filaments like Pseudanabaena limnetica Lemmermann).This group was followed by C-Strategists (small green characterised fast nutrient...

Twenty-four new records for freshwater algae of Turkey were determined in a study conducted from February 2007 to January 2009 Çaygören Reservoir, Balıkesir, Turkey. Among these, 3 Cyanobacteria, Euglenophyta, 15 Chlorophyta, 1 Charophyta, Heterokontophyta, and was Dinophyta.

Molecular techniques are used today in many areas and have increased the confidence level of studies. The aim study was to compare classical morphological characters coccoid green algae under field culture conditions by using modern molecular analysis. To achieve this aim, we first isolated from Liman Cernek lakes. variations were observed phylogenetic relationships these strains defined according 18S rRNA gene sequences. According sequence analysis, 2 species had high similarity Scenedesmus...

This study on epipelic algal flora and its seasonal variations in the Küçükçekmece Lagoon, Turkey was carried out between May 2001 June 2002.A total of 109 species were identified, most which belonged to Bacillariophyta (64 taxa).Other taxa identified included members Cyanophyta (26), Chlorophyta (13), Euglenophyta (5) Phaeophyta (1).Bacillariophyta dominant terms number abundance at five stations.The seasonality different all stations.Lower cell numbers registered St. 5. Pennate diatoms...

Mixotrophic protists, combining both heterotrophy and phototrophy, are found abundantly in eutrophic waters.Dinobryon sertularia Ehr. from Chrysophyceae (golden algae) mixotrophic organisms often make up blooms colony pools, lakes dam reservoirs.This study was carried out Derbent Dam Lake the Middle Black Sea Region.Seasonal dynamics biomass of D. were investigated at four stations between February 2001 July 2002.D. consisted 47-60% spring, 61-79% summer, 82-88% autumn all phytoplankton...

Abstract Diatoms are one of the key organisms used in biomonitoring studies and they occur a wide variety environments, exhibiting broad range tolerance to abiotic factors. Historically, first freshwater diatom study Turkey was conducted 1844 by Ehrenberg based on material collected from Murat Aras Rivers. Situated between large continents (Eurasia Africa), comprises areas very diverse geological, climatic environmental conditions, so we should expect that such as diatoms show high diversity...

This work analyses the seasonality of phytoplankton (species richness, biovolume, diversity, abundance and dominance) associated with some physical, chemical climatic variables shallow turbid lake (Tatlι Lake, Turkey) between February 2000 April 2001. Samples were collected monthly from two stations surface (0–20 cm). Species richness diversity (Shannon-Weaver, H’) index calculated. Seasonal changes in community structure (i. e., species present their relative abundances) evaluated Nonmetric...

A total of 59 species epizoic algae were recorded from the carapace Emys orbicularis (Linnaeus, 1758) (Testudinata, Emydidae). Division wise distribution Cyanophyta 26, Chlorophyta 13, Euglenophyta 5 and Chrysophyta 15. Among Phormidium ambiguum, Pseudanabaena limnetica, Chroococcus spp. Microcystis observed intensively.

This study aimed to investigate molecular taxonomic diversity of unicellular chlorophyte strains in the northern Anatolian freshwater habitats Turkey. Five were isolated from various i.e. salty lagoons, shallow lakes, or slow-flowing creeks. The chosen Cernek lagoon (Kızılırmak Delta, Samsun), Kara lake (Çubuk, Ankara), Sarıkum (Sinop), and Sırakaraağaçlar creek (Sinop). Although observations based on light microscopy showed no significant differences cell morphologies, phylogenetic analysis...

Phytoplankton of Karamık Lake consists 175 species vvhich belong to Bacillariophyta, Chlorophyta, Chrysophyta, Cryptophyta, Cyanophyta, Dinophyta and liuglennphyta divisions. The fact that a great part the lake is covered with rushes has inereased number epipelic epiphylic origin. In phytoplankton, Chlorococcales Desmidiales members have been recorded as ıvidespread abundant but Cyanophyta seconekate importance. Most existing are characteristics eutrophic lakes. compound indices value found...

ABSTRACT We surveyed the epizoic algae growing on Emys orbicularis from several sites in Central Anatolia region of Turkey during nesting season (May-August) 2005. Fifty-three species were found carapaces thirty-five E. Orbicularis, with considerable variation algal communities different sites.
