A Systems Level Approach to Biogeography
Microbial simulations bridge the gap between the molecular and ecosystem scales.
A new CBIOMES paper presents, for the first time, an interpretation of observed, strain-level, basin-scale biogeography using genome-scale modeling of cellular metabolism, physiology, and fitness. Continue reading A Systems Level Approach to Biogeography

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.

When Phytoplankton Go Hungry
by Helen Hill for MIT CBIOMES
The Redfield ratio, the atomic ratio of carbon, nitrogen, and phosphorus (C:N:P) in phytoplankton and deep ocean waters, has often been treated as a constant 106:16:1. A new paper involving several CBIOMES co-authors, among them two from the MIT Darwin Group, presents compelling evidence for what causes this ratio to change within phytoplankton. Continue reading When Phytoplankton Go Hungry
