TL;DR: Akinete formation enables cyanobacteria of the order Nostocales to survive adverse conditions and is assumed to be a prerequisite for the invasion of tropical species like Cylindrospermopsis raciborskii into the temperate zones.

TL;DR: This work calibrated and validated the model using a 13-year data set on the species' population dynamics gathered in a shallow lake in northern Germany, and showed that the seasonal dynamics of C. raciborskii are mainly determined by the optimum growth temperature of its vegetative cells.

TL;DR: The implementation of an improved catalysed reporter deposition (CARD)-fluorescence in situ hybridization (FISH) protocol to assist the identification and quantification of akinetes in sediment samples is presented.

TL;DR: It is concluded that below 20°C photoinhibition is avoided by greater photoprotection in the invasive species C. raciborskii compared to the native species A. gracile.

TL;DR: Based on measured and calculated long-term data on external phosphorus load (1920-2009), hypolimnetic P accumulation and trophic parameters for the dimictic Lake Scharmutzelsee, the authors aimed to identify factors which cause variable P net sedimentation and the importance of internal P loading for different time periods especially focusing on nonsteady state after abrupt external load reduction in 1988.
