WitrynaMolecular clock analyses have previously shown that marine planktonic cyanobacteria evolved toward the end of the Pre-Cambrian ( Sánchez-Baracaldo et al., 2014; Sánchez-Baracaldo, 2015; Schirrmeister et al., 2015a) likely contributing to the widespread oxygenation of the oceans. WitrynaProject description:Marine planktonic cyanobacteria contributed to the widespread oxygenation of the oceans towards the end of the Pre-Cambrian and their evolutionary origin represents a key transition in the geochemical evolution of the Earth surface.Little is known, however, about the evolutionary events that led to the appearance of …

Origin of marine planktonic cyanobacteria — University of Bristol
Witryna13 sty 2016 · Cyanobacteria developed over semi-mixed conditions (May–June 2006) and during the thermal stratification (July 2005). The cyanobacterial abundance and biomass was evident between 20 and 35 m in inshore stations and between 20 and 25 m in deeper stations during the semi-mixing conditions and stratification. Witryna14 kwi 2024 · Cyanobacteria can cope with various environmental stressors, due to the excretion of exopolysaccharides (EPS). However, little is known about how the composition of these polymers may change according to water availability. This work aimed at characterizing the EPS of Phormidium ambiguum (Oscillatoriales; … Witryna1 gru 2015 · It is shown that marine planktonic cyanobacteria evolved from benthic marine and some diverged from freshwater ancestors during the Neoproterozoic … diagnosis murder man overboard cast
