In the Palau Bontosua area, in the southwestern portion of the Indonesian island of Sulawesi, all the degraded coral reefs have been restored in just four years.Due to global warming and human activities, the coral reefs in the area had been virtually destroyed.But now, thanks to a specific restoration program, they are growing at the same rate as healthy ones.To allow the corals to reform, barriers have been installed hexagonal steel structures covered with sand, which stabilizes debris and provides a habitat for reef fauna.However, although this is an excellent result, the researchers warn that the technique used represents a last resort which should not be used systematically.The barriers thus restored present in fact a lower species diversity compared to healthy ones. A team of Indonesian and British scientists worked on the project as part of the Mars Coral Restoration Program, a large-scale effort to restore the coral reefs destroyed by fishermen who used explosives to kill and c...

While mapping the seabed using a remote-controlled vehicle, a group of researchers equipped with laser scanners he discovered two pristine coral reefs in the waters off the coast of the Galápagos Islands, a volcanic archipelago in the Pacific Ocean, considered one of the main destinations in the world for observing unique animal and plant species and one of the largest marine protected areas in the world.The two barriers, habitats of numerous living species, were most likely formed thousands of years ago.However, studies on coral structures located in deep waters are less widespread than those carried out on more superficial ones.However, the knowledge gathered to date says that the former, despite being colder, darker and deeper than the latter, which thrive thanks to sunlight, they actually host the majority of all coral species and act as a refuge for many animals.Reasons that pushed Stuart Banks, a marine scientist who carries out conservation research in the Galá...

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...
