Effect of flow velocity on phytoplankton biomass and composition in a freshwater lake

The Influence of a Eutrophic Lake to the River Downstream: Spatiotemporal Algal Composition Changes and the Driving Factors

“…The total abundances were significantly negatively related to reach lengths and the TT because Cyanobacteria (mainly Microcystis), originated from the Dianchi Lake, are not adapted to turbulent flow [6,15,16]. On the contrary, they tend to be favoured under scenarios of weak mixing, reduced discharge and slow flows [11,[42][43][44][45].…”

“…Thus, the buoyant Microcystis will still float upwards to have fully photosynthesis and in consequence impede their competitors in those lakes. Li et al [16] found that flow velocities between 0 and 0.10 m/s would promote the rapid growth of phytoplankton. However, the higher flow velocity would inhibit phytoplankton growth.…”

“…Many existing cases have proven that intensified turbulence of water may lead to algae species shift from buoyant Cyanobacteria to sinking Bacillariophyta [14][15][16][17]. However, these experiments were conducted in the same aquatic systems (either in lakes or in rivers) rather than in the lake-to-river coupled systems.…”

Assessment of Chemical Pollution With Routine Pesticides Using PRIMET, a Pesticide Risk Model in the Benoe Stream in the South-West Region of Cameroon

“…This may account for the seasonal variation in the water parameters of the stream. Hydro-meteorological factors such as water flow, rainfall and temperature change significantly relate to the temporal and spatial dynamics of phytoplankton (Li et al, 2013).…”

Study of the application of the water-lifting aerators to improve the water quality of a stratified, eutrophicated reservoir

“…Summer stratification generally favors potentially toxic cyanobacterial biomass due to their higher affinity for nutrients compared to other phytoplankton species and their ability to adjust their buoyancy and therefore exploit nutrients, light and inorganic carbon resources over a wider range (Liu et al, 2012;Wynne et al, 2008). A number of ecological engineering techniques have been used to control cyanobacteria blooms, such as altering the hydrology to enhance vertical mixing and flushing to counter the formation of cyanobacteria surface blooms (Li et al, 2013;Lundgren et al, 2013;Thackeray et al, 2006), the operation of a bypass to decrease nutrient loads and the transportation of phytoplankton from upstream areas to the reservoir (Yajima et al, 2013), and bio-manipulation by means of introducing fish to increase the grazing pressure on cyanobacteria. Unfortunately, application of these techniques in other reservoirs has several limitations; meanwhile, the reservoir management department also wants to use more effective technique to control cyanobacterial bloom in situ (Upadhyay et al, 2013).…”
