Control of cyanobacterial blooms

Cyanobacterial blooms would be less intense in the future.

Mechanism of control of cyanobacterial blooms.

In a study carried out among researchers from EFPU, Walter Helbling and Virginia Villafañe, and from the Universidad Autónoma de México (UNAM), Anastazia Banaszak, the responses of several species of cyanobacteria to a combination of variables associated to global change were evaluated.  The results of these investigations reveal that in a scenario of global change for mid latitudes, in which predictions are of higher temperatures, more opaque environments (with higher amounts of dissolved organic matter) and stronger winds (that produce mixing of surface waters), cyanobacterial photosynthesis will be more inhibited by ultraviolet radiation that under present conditions such that it is expected that blooms will not develop intensely in the future.
