Cyanobacteria were amongst the first organisms colonising the sea about 3.5 billion years ago. They were the first to be able to transform the CO2 present in the atmosphere into O2 through the photosynthesis process which is common to all organisms possessing the Chlorophyll a pigment (such as terrestrial plants and trees). Therefore, Cyanobacteria transformed the CO2 and methane rich atmosphere into the oxygenated atmosphere that allowed evolution towards the human existence.<\/p>\n\n\n\n

Nowadays, these photosynthetic microscopic organisms are still great contributors for the oxygen supply to the atmosphere and thus play an essential role in slowing down the increase of CO2 levels from Climate Change. <\/p>\n\n\n\n

However, in spite of all the benefits arisen from Cyanobacteria to mankind (not only ecological but also with applications in biotechnology, pharmacology, medicine, etc.), some species may contain strains able to produce toxins that may put at risk the human health. This can be a problem when these toxic cyanobacteria multiply massively, leading to blooms forming green scums that are visible from space. In freshwaters, the effects of such blooms can be more severe due to the population dependence on the freshwater supply.<\/p>\n\n\n\n

Therefore, it is very important the development of wide monitoring strategies for early warning of cyanobacterial blooms occurrence, particularly in freshwater bodies. However, this requires previous information on cyanobacterial dyanmics in order to detect and predict blooms. During my PhD and post-doc, I have studied several molecular and ecological aspects of Cyanobacteria. <\/p>\n\n\n\n
