Mystery of creepy "bloody" the rains and tides

Creepy "bloody" the rains and the tides are explained by the proliferation of red algae. Aquatic organisms extend the range of their habitat due to its full universality.

In the diet of toxic red algae is included as organic, for example, fertilizer urea, and inorganic substances such as nitrogen. Therefore, these dinoflagellates are never hungry, choosing those products, which is in the water in abundance, says Sergey Skarlato from the Institute of Cytology RAS in St. Petersburg.

"Bloody" the rains and the waves, painted in crimson color, for several years, scaring the inhabitants of Spain and the Caribbean. Believers such phenomena are associated with the end of the world and cause panic. And although the Apocalypse is a red-brown water does not portend the anomaly is a danger to the environment.

Red algae, which caused the color change of the rains and tides, toxic. Other microorganisms, as well as fish and poultry, close to them die. Lacking micronutrients, the algae secrete a poison brevetoxin, killing competitors in the area.

The secret of the prosperity of the algae Prorocentrum minimum revealed on the Baltic sea, where they survived all native species of plankton. In addition to venom, red algae possess several abilities. For example, if the water is salted, they accelerate the metabolism to the work DNA and proteins has not been violated.

Artificially deprived of their main food — inorganic compounds of nitrogen, algae quickly switched to urea.

These properties explain why the red algae were able to quickly occupy the Baltic sea, where salinity and the distribution of nutrients uneven.

The purpose of the study and future observations, says scarlata to collect data to predict an intense multiplication of algae. Then this process can be controlled, saving the species living nearby.
