Ocean microbes get their diet through a surprising mix of sources, study finds
Up to one-third of the carbon consumed by Prochlorococcus may come from sources other than photosynthesis. Continue reading Ocean microbes get their diet through a surprising mix of sources, study finds
Small eddies play a big role in feeding ocean microbes
Swirling waters replenish nutrients in open ocean, a new study finds, and could mitigate some climate change effects. Continue reading Small eddies play a big role in feeding ocean microbes

New model sheds light on day/night cycle in the global ocean
Computer models of global ocean biogeochemistry typically don’t include the day/night light cycle. CBIOMES researchers are. Continue reading New model sheds light on day/night cycle in the global ocean

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.
