ecosistema marino

It increases exceptionally presence of corals and significantly decrease the marine waste, while there is a proliferation of numerous alien species and a worrying one decrease in posidonia vegetation.This is the situation of the Mediterranean marine environment, photographed in the latest report of theIspra, presented at a conference in Palermo as part of the national system for the protection of the marine ecosystem. Specifically, Ispra has registered formations of corals in 8 Italian regions and 160 sites under study.The names of the main species observed are eunicella, pentapora and paramuricea.In 9 regions, within 37 monitoring areas, "rhodolith beds" were also found, i.e. small calcareous algae similar in shape to popcorn. The data, however, are not very positive in relation to oceanic posidonia off the Italian coast, which was monitored in all the regions touched by the Tyrrhenian and Ionian Seas and in the lower Adriatic area.Ispra's analyzes have shown that 25 percent...

In the depths of the Pacific Ocean, off the coast of Central America, a new marine ecosystem has been discovered by an international team of scientists, who, thanks to the help of a robot, have managed to shed light on what is found in the cavities located under the hydrothermal vents of an underwater volcano.It is right there, precisely at 2,500 meters deep, that the ecosystem is hidden, teeming with worms, snails and bacteria chemosynthetics that live in water at a temperature of 25 degrees centigrade.A discovery of fundamental importance, which gives new certainties to our knowledge of the marine world:now, in fact, the presence of habitats around the hydrothermal springs existing in the great sea depths has been substantially certified, a hypothesis that until now could not be taken for granted.A discovery which also calls us to question the importance of preserving the oceans, precisely at a time when more and more countries are embarking on deep-sea exploration projects for the e...
