Plastic biodegradation in natural environments is performed by the microbial biofilm living on its surface. This study identifies for the first time plastic degraders in marine environment, by using stable isotope tracers. Polyhydroxybutyrate (PHB) biodegradation was proved by monitoring microbial…

Positive interactions in a warmer and more acidic ocean: crustose coralline algae holobionts enhance gorgonian larval settlement under climate change

Elisabetta Manea, Pierre E. Galand, Steeve Comeau, Christine Ferrier-Pagès, Bruna Giordano, Laura Pezzolesi, Jean-Baptiste Raina, Romie Tignat-Perrier, Lorenzo Bramanti

Background: The increasing frequency of marine heatwaves is leading to mass mortality of gorgonians in the Mediterranean Sea, threatening some populations with local extinction. A better understanding of the dynamics of gorgonians' early life stages under climate change is urgent to ensure…

Expanding a network of marine protected areas based on functional rather than structural connectivity is more profitable

Sylvain Blouet, Thibaud Tournadre, Skandar Hentati, Katell Guizien

One strategy to boost population resilience and stop the long-term loss of ocean biodiversity is to establish networks of interconnected, highly protected areas. In this study, we assess the relationship between profitability and adequacy brought about by structural and functional connectivity in…
