Wild salmon are disappearing from the world’s oceans, but it is not entirely clear why or how we can stop it. Chinook salmon, also known as king salmon, is the largest species in the family Salmonidae. And yet, most populations in the contiguous United States are threatened with extinction. In addition to the many threats these fish face in their freshwater habitat, recent models have revealed that the ocean stage is at substantially higher risk due to climate change. Warming…

Microplastics in the oceans: the many ways they can harm coral life

Microplastics are one of the main threats to marine ecosystems, but the mechanisms determining their impact on marine life are still largely unknown. We investigated the impact of microplastics on the red coral, an emblematic and threatened species belonging to the Corallium genus, which is distributed at almost all latitudes and depths. We report here that microplastics are ingested and accumulated by corals (primarily polypropylene and polystyrene), either directly (as microplastics are confounded with the coral’s prey, plankton) or through…
