The recovery of seal populations all over the world has led to concerns over how their interaction with fisheries will affect fish stocks now and in the future. However, a new study published this month in Ambio and led by scientists at Stockholm University has shown that in fact human-driven influences such as climate change and fishing are the main culprit in declining the stocks of Baltic cod, herring and sprat.

Barely living "zombie" bacteria and other forms of life constitute an immense amount of carbon deep within Earth's subsurface—245 to 385 times greater than the carbon mass of all humans on the surface, according to scientists nearing the end of a 10-year international collaboration to reveal Earth's innermost secrets.

The future of the world’s coral reefs is uncertain, as the impact of global heating continues to escalate. However, according to a study published today (December 11) in Nature Climate Change, the response of the Great Barrier Reef to extreme temperatures in 2017 was markedly different to one year earlier, following two back-to-back bouts of coral bleaching. Remarkably, corals that bleached and survived 2016 were more resistant in 2017 to a recurrence of hot conditions.

The Chagos Archipelago, a remote British Indian Ocean Territory (BIOT) located 500 kilometers south of the Maldives, is one of the most pristine marine environments on earth. Now a £1million grant will allow scientists from the University of Plymouth to embark on a two-year program to identify what underlying mechanisms keep the region's seas - and the species living within them - so healthy.
