Record Heatwave Drives Spread of Alien Species and Pathogens in Mediterranean

A record heatwave in the Mediterranean is driving the proliferation of invasive alien species and pathogens, including the Portuguese man-of-war and a flesh-eating bacterium. The article details how rising sea temperatures are altering marine ecosystems, increasing the presence of these dangerous organisms along popular tourist coasts. It specifies locations where these species have been observed and outlines the health risks they pose to swimmers and coastal residents. The phenomenon is linked to climate change, which is expanding the habitat range of tropical species into temperate waters. Local authorities are issuing warnings and monitoring the situation, but the spread is expected to continue as ocean warming persists.

Global Impact

This story has significant environmental and economic dimensions. Environmentally, the spread of alien species and pathogens signals a fundamental shift in marine biodiversity driven by climate change, with long-term consequences for ecosystem health and fisheries.
