Many of the Caribbean’s most important reefs are going unprotected

Healthy coral reefs can significantly reduce hurricane damage for coastlines, yet many still face harms, including pollution and ship damage, that people have the power to stop.
In the last two decades, as a result of climate-driven sea warming, almost half of commercially relevant fish in the Mediterranean have been deserting their original habitats in their quest for higher latitudes, depths and cooler waters. KinoMasterskaya / Shutterstock

What fish redistribution in the Mediterranean is telling us about species’ climate resilience

The Mediterranean is one of the world’s most vulnerable ecosystems. A scientific study on shifting distribution dynamics examines how its fish species contend with sea warming.
According to UNESCO, in 2022, there is a 100% chance of a tsunami of at least one metre high in the Mediterranean Sea in the next 30 years. France’s Côte d’Azur happens to be one of the most seismically active areas in Western Europe. Arno Smit/Unsplash

Lifting the lid on unknown coral microbiomes living in the Pacific ocean

Several years worth of findings from a floating laboratory have tapped into a well-stocked coral library of taxonomic, genetic and chemical diversity, previously unknown to Science and Medicine.
