Success of chrysophytes, cryptophytes and dinoflagellates over blue-greens (cyanobacteria) during an extreme winter (1995/96) in eutrophic shallow lakes

Spatial and temporal dynamics of phytoplankton communities in a Great Lakes drowned river-mouth lake (Mona Lake, USA)

“…During winter stratification when the lake is frozen and nutrients concentrations are low , the phytoplankton community was dominated by chlorophytes and dinoflagellates. These algal groups are not uncommon for ice-covered eutrophic lakes (Wiedner and Nixdorf, 1998) but this finding disagrees with the PEG model's prediction of winter dominance by diatoms. De Senerpont Domis et al (2012) noted that system-based deviations from PEG are to be expected because it emphasizes physical factors, grazing, and nutrients rather than biological drivers such as microbial organisms, parasites, and fish.…”

Winter phytoplankton communities in different depths of three mesotrophic lakes (Łęczna-Włodawa Lakeland, Eastern Poland)

“…Such species were determined during winter also by other authors (Squires & Rushforth 1986;Phillips & Fawley 2002b). Cyanoprokaryota, which in our studies occupied usually lower layers of studied water column are rather rare in winter phytoplankton, but have been occasionally reported usually as filamentous species (Spaulding et al 1993;Wojciechowska et al 1998;Wiedner & Nixdorf 1998).…”

“…They belonged to Cryptomonas and/or Rhodomonas genera, which are often observed in great numbers during the winter period (Jones & Ilmavirta 1978;Stewart & Wetzel 1986;Wiedner & Nixdorf 1998;Barone & Naselli-Flores 2003). The peak of cryptomonads population under the ice could be expected because of their ability to grow in very low light and temperature intensity (Steward & Wetzel 1986).…”

“…The other flagellates, which reached a considerable share in total phytoplankton number of the upper layer were Euglenophyta, Dinophyceae and Chrysophyceae species. All of them were often recorded in winter seasons in different temperate lakes (Wright 1964;Wiedner & Nixdorf 1998;Danilov & Ekelund 2001;Mencfel & Pasztaleniec 2004).…”

Mixotrophy, allelopathy and the population dynamics of phagotrophic algae (cryptophytes) in the Darss Zingst Bodden estuary, southern Baltic

“…In cold winters cryptophytes dominate the phytoplankton community. Light and temperature are the factors that trigger the switch in dominance to flagellates (Wasmund 1994, Wiedner & Nixdorf 1998; shallow eutrophic lakes in Brandenburg, cyanophyte-dominated from early spring to late autumn, comparable to DZBC).
