Warming seas threaten key #phytoplankton species that fuels the #foodweb, study finds
“These are #keystonespecies — very important ones,” said François Ribalet, a research associate professor at the University of Washington’s School of #Oceanography and the study’s lead author. “And when a keystone species decreases in abundance, it always has consequences on #ecology and #biodiversity. The food web is going to change.”

Millions of tonnes of #nanoplastics are polluting the #ocean
These #plastic particles smaller than a human hair can pass through cell walls and enter the #foodweb

These particles, smaller than one micrometer in diameter, behave differently from larger microplastics by remaining suspended throughout the water column rather than settling to the ocean floor. The nanoplastics can pass through cell walls and enter the marine food web through #phytoplankton.

Good timing:
Miriam @mseifert received the @MARUM #researchaward yesterday, and her final PhD chapter was published just in time:

Taking into account #interactive effects of multiple environmental changes can even flip the sign of primary production change until 2100 (here, this occurred for diatoms in the Southern Ocean).

Interaction matters: Bottom‐up driver interdependencies alter the projected response of #phytoplankton communities to #climate change
