TL;DR: Cyanobacteria should not be treated as a single group when considering the potential effects of changes in nutrient loading on phytoplankton community structure and neither should the N2-fixing Nostocales, as the two most abundant potentially toxin producing Nostocale in this study were found in lakes with high N relative to P enrichment.

TL;DR: This is the first global quantitative synthesis on under-ice lake ecology, including 36 abiotic and biotic variables from 42 research groups and 101 lakes, examining seasonal differences and connections as well as how seasonal differences vary with geophysical factors.

TL;DR: It is concluded that an earlier rise in water temperature associated with climate change has promoted the spread of C. raciborskii to the temperate zone, thereby shifting the pelagic populations to a phase with higher Imix, which advances growth and the population establishment.

TL;DR: CYN occurrence in the German lakes could not be ascribed to the three known CYN-producing species Cylindrospermopsis raciborskii, Anabaena bergii and Aphanizomenon flos-aquae, which were detected in some lakes in low abundances, and the highest correlation coefficients were observed between particulate CYN and the native AphanIZomenon gracile.

TL;DR: Any further temperature increase would promote the growth and development of Nostocales species in general, and that of the invasive species in particular, and would enable a more northward expansion of A. ovalisporum.
