Arctic sea ice algae contaminated with microplastics have serious consequences for ecosystems and the climate.
Artificial light is an emerging threat for marine ecosystems in coastal waters (Kochi, India).

We need to advance our understanding of the effects of microplastics on aquatic ecosystems, especially on small animals at the base of food webs that might be ingesting more of these particles.
Spring herring and Atlantic mackerel fisheries are among the most lucrative in the Gulf of St. Lawrence, and brought in more than $1.3 billion to Québec and Atlantic fishers in 2020.

DNA sequencing is making it possible for scientists to identify thousands of species of zooplankton – drifting animals that are key links in ocean food webs.
Sustained ocean warming could greatly reduce catches of fish like these herring photographed off Norway.

Fish are a key food source for millions of people worldwide. But a recent study finds long-term warming over the next 200 years could starve tiny plankton, with impacts that would ripple up food chains.
Young African penguins are following the usual cues to feeding grounds only to find that the sources of food in these places is no longer available. This is devastating for their numbers.
Watch out, there’s a mixotroph about.

They ‘engulf living prey, suck out their innards, poison them, harpoon them, make them explode, and steal and reuse body parts’. And we ignore them at our peril.
