“…Tsujimura and Okubo (2003) found that high temperature triggered cyanobacterial blooms in a small eutrophic Japanese reservoir. Akbay et al (1999) found that Bacillariophyta was the most abundant phytoplankton group during spring in Turkish lakes. They related this pattern of diatom recurrence to relatively cool, but not extremely cold waters.…”

AbstractÇelik, K. and T. Ongun. 2006. Seasonal dynamics of phytoplankton assemblages across nutrient gradients in shallow hypertrophic Lake Manyas, Turkey. Lake and Reserv. Manage. 22(3):250-260.Species composition, abundance and size distribution (the average measure of the longest cell dimension and surface area to volume ratio) of phytoplankton in the shallow hypertrophic Lake Manyas, Turkey were studied between January 2003 and December 2004. A total of 165 species were recorded during the study. Diatoms and Cyanobacteria were the dominant taxa at most stations. Nitrate and phosphate values showed a decreasing gradient with the distance from Sigirci Inlet to Karadere Outlet. Bacillariophyta dominated the phytoplankton in spring, while Cyanobacteria prevailed in summer. Each summer, a peak of Euglenophyta was also observed at Sigirci Inlet. Nutrient gradients seemed to have a greater control over overall density than of species composition. The size distribution of the Cyanobacteria showed positive correlations with nutrient levels, while green algae and diatoms did not. There was a negative correlation between the average cell dimension of the phytoplankton cells and the surface area to volume ratio in general. The objective of this study was to determine the seasonal dynamics of species composition, abundance and size distribution of phytoplankton assemblages across nutrient gradients along a distance in the shallow hypertrophic Lake Manyas, Turkey.

“…Therefore, certain groups of phytoplankton, especially blue-green algae, can degrade recreational value of surface water, particularly thick surface scum, which reduces the use of amenities for contact sports, or large concentrations, which cause deoxygenation of the water leading to fish death [4]. Over the last few decades, there has been much interest in the processes influencing the development of phytoplankton communities, primarily in relation to water quality [5][6][7]. The algae co-occur even though each species has a specific niche based on its physiological requirements and the constraints of the environment.…”

Seasonal changes in the diversity of phytoplankton and its relationships to the water quality in Büyükçekmece Watershed in Istanbul, Turkey were studied in this study during one-year period, from January 2009 to December 2009. Physico-chemical parameters, main criteria of water quality, were observed. Having identified species from 6 divisions, including Bacillariophyta, Chlorophyta, Cyanophyta, Euglenophyta, Dinophyta and Cryptophyta within the phytoplankton of Büyükçekmece Lake, and that of the named influent streams, Bacillariophyta among these divisions has been specified as the richest group in species variety. Among the streams having gone under sampling, Tahtaköprü Stream has displayed the species variety (48), and respectively Karasu (45), Hamza Stream (32), Beylikçayırı Stream (21) and Ahlat Stream (7) have come thereafter. Within the phytoplankton of Büyükçekmece Lake, 66 species have been identified. It was determined that the water qualities of Büyükçek-mece Lake and related streams were varies I, II and III.

“…During recent times, there has been much concern in the processes influencing the growth of phytoplankton communities mainly in relation to physico-chemical factors (Akbay et al, 1999;Peerapornpisal et al, 1999;Elliott et al, 2002). However, most of the studies on Sri Lankan reservoirs have been focused on the composition and diversity of planktonic algae (e.g.…”

Abstract:. Cyanobacterial and dinoflagellate blooms have a range of social, environmental and economic impacts due to their potential of toxin production under extreme environmental conditions. Therefore, the present study aimed to understand the species abundance, distribution and the relationship between species distribution and measured environmental variables within the 45 reservoirs studied, covering three major climatic regions of Sri Lanka (Wet, Intermediate and Dry). Plankton samples were obtained using a 34µm plankton net. Both field and laboratory analyses were conducted to obtain limnological data of each reservoir. Multivariate statistical techniques were used to understand the species distribution along measured environmental gradients. Thirteen species of Cyanobacteria were identified and seven of them were toxigenic. The Dry Zone showed the highest diversity of Cyanobacteria including toxigenic species and the Wet Zone showed the lowest. While Cylindrospermopsis raciborskii was the dominant species recorded in 22% of the sampled reservoirs, Pseudoanabaena limnetica was the least dominant. Only one species of Dinoflagellate, Peridinium aciculiferum was identified from all the climatic regions. Multivariate statistical analysis revealed that temperature is the most important environmental variable that determines the species variation and abundance among the sites.
