Functional Classification and Composition of Phytoplankton in Liman Lake
Functional classification and composition of phytoplankton of Liman Lake were studied between January 2002 and December 2003. A total of 109 taxa belonging to Bacillariophyta, Chlorophyta, Cyanophyta, Dinophyta, Xantophyta, Chrysophyta and Cryptophyta were identified. The succession during 2002 began with R-Strategists (with a high surface to volume ratio, including blue-green algae with filame...
متن کاملImpacts of hydrodynamics and benthic communities on phytoplankton distributions in a large, dreissenid-colonized lake (Lake Simcoe, Ontario, Canada)
We quantified the vertical and horizontal variation of chlorophyll a (Chl-a) to test how benthic filter feeders (dreissenid mussels), rooted macrophytes, and hydrodynamics influence phytoplankton distributions in a large lake (Lake Simcoe, Canada). Water column Chl-a did not differ significantly among sites of different depth, distance offshore, or rooted macrophyte biomass, but among the nears...
متن کاملPhytoplankton composition and diversity in Gorgan Bay, Golestan province
This study was carried out to investigate the phytoplankton composition in Gorgan Bay. Water samples were collected from 11 selected sites in Golestan bay, monthly from March to February. Thirty five genus were identified among which Bacillariophyta was the dominate group with 17 genus, while the Euglenophyta had the minimum. Abundance and biomass of phytoplankton showed spatial and temporal va...
متن کاملPhytoplankton composition and microcystin concentrations in open and closed bays of Lake Victoria, Tanzania.
This study was carried out in order to investigate the spatial variation of algal toxin (microcystin) concentrations along the shoreline of Lake Victoria. A total of 16 nearshore stations differing in connectivity to the main lake basin were categorized as either closed bays (ratio of bay area to bay opening < 1) or open bays (ratio ≥ 1) and sampled during November and December 2009. Water samp...
متن کاملThe Impact of Zooplankton Grazing on Phytoplankton Species Composition and Biomass in Lake Champlain (USA-Canada)
Rates of grazing on phytoplankton by macrozooplankton (cladocerans and copepods > 220 μm in length) and microzooplankton (animals < 220 μm, mostly rotifers and nauplii) were determined for Lake Champlain on three occasions using a modified version of the Lehman-Sandgren method. Gradients in grazer density were created in fertilized cubitainers incubated in situ, and clearance rates on specific ...
