Pathogens, storms and extreme temperatures: the causes of mass sea urchin deaths

  • No comments
A pair of studies from Tel Aviv University map 110 mass mortality events of sea urchins since 1888 and show that pathogens are the main cause, while also presenting a "corona swab" method for non-invasive genetic sampling under the skin.

New research from King Abdullah University in Saudi Arabia reveals that the Red Sea dried up and became an arid salt basin, until it was flooded again by a massive flood from the Indian Ocean – an event that changed the geological history of the

Corals in the Gulf of Eilat withstood an unprecedented marine heat wave and remained stable

  • No comments
International study led by researchers from the Hebrew University reveals that Eilat corals survived four years of heat waves, including 30 DHW in the summer of 2024 – the highest in the world; spot bleaching observed for the first time in shallow waters

Stony Corals: Reef Builders and Guardians of the Underwater World

Dr. Tom Schlesinger explains how tiny, fragile creatures create vast ecosystems, why they are sensitive to the climate crisis, and how childhood in Eilat led him to explore one of the great secrets of the sea.

The global sea urchin population is in real danger for its continued existence

The plague that destroyed the sea urchins in Eilat has spread to the Indian Ocean and threatens to destroy sea urchin populations all over the world

Thus the Houthi threat may increase the pollution of cargo ships

Beyond the security and economic implications, the Houthi threat to the Red Sea may also have significant environmental consequences, which will further increase the polluting footprint of the maritime transport industry

Corals from the Red Sea have invaded Israel's Mediterranean coast

  • No comments
Until now, the low temperatures of the Mediterranean water in winter have been a barrier to the arrival of tropical corals. The establishment of the Dendronaphtia we found indicates that at least last winter, the waters of the Mediterranean Sea were warmer than before
