Congratulations, Dr Deepa Rao!

Observations suggest diazotrophs like Crocosphaera and Trichodesmium pay for their ability to fix nitrogen with a very low growth rate, yet diatom-diazotroph associations or DDAs exhibit high growth rates. CBIOMES postdoctoral fellow Chris Follett and co-authors use a cell flux model to test the hypothesis that diatom-diazotroph associations or DDAs grow faster than unpaired diazotrophs because the diatoms in DDAs provide organic carbon to their diazotroph guests that boost their growth rate.

Antarctic Marine Microbes Need Their Multivitamins
In the austral summer season of December 2017 – February 2018, Deepa Rao participated in the NSF funded CICLOPS cruise to explore cobalamin and iron co-limitation of phytoplankton species in Terra Nova Bay, Antarctica. Continue reading Antarctic Marine Microbes Need Their Multivitamins

Seeding Oceans with Iron may not Impact Climate Change
Darwin Project study led by Jonathan Lauderdale finds Earth’s oceans contain just the right amount of iron; adding more may not improve their ability to absorb carbon dioxide. Continue reading Seeding Oceans with Iron may not Impact Climate Change
Exploring Phytoplankton Diversity
reporting by Helen Hill
In a new paper, MIT-CBIOMES investigator Stephanie Dutkiewicz and collaborators use the Darwin ecosystem model to develop theories seeking to explain and predict phytoplankton biogeography.
