A new study shows that the biological effects of two ecosystem changes can be greater than their individual impacts

November 3, 2017 —What do Jellyfish teach us about climate change?

A lot. At least that’s what I learned after reading a very recent paper out in the journal Global Climate Change. The article, “Ocean acidification alters zooplankton communities and increases top- Continue reading What do Jellyfish teach us about climate change

Behavioural evidence suggests marine organisms are not just ingesting microplastics by accident but actively seeking them out as food

August 16, 2017 — Fish may be actively seeking out plastic debris in the oceans as the tiny pieces appear to smell similar to their natural prey, new research suggests. Continue reading Fish mistaking plastic debris in ocean for food, study finds
