- Happy to share our new work on Temperature-driven biogeography of marine viruses infecting Micromonas: academic.oup.com/ismecommun/a...
- We integrated mathematical modelling with in situ metagenomics using the TARA Oceans and TARA Arctic datasets, and we recapitulated virus presence and absence in the ocean through a model describing temperature-driven cell-based interactions between viruses and phytoplankton.
- Thanks for the great collaboration with Prof. Hiro Ogata and Dr. Hisashi Endo at the Institute of Chemical Research of @kyotouniversity.bsky.social; Prof. @joshuasweitz.bsky.social at the @umaryland.edu; and our funders, The @simonsfoundation.org and the ICM at Kyoto University 🙏

- Reposted by David DemoryHappy to share that our work on viral infection of cyanobacteria in the Southern Ocean has been published 🦠❄️🌊 doi.org/10.1111/1462... Thank you to all the collaborators in this project @d2mory.bsky.social @joshuasweitz.bsky.social @biologytechnion.bsky.social
- Delighted to share our new preprint on bioRxiv: www.biorxiv.org/content/10.1... Where we integrated viral metagenomics and mathematical modelling to explore the temperature-driven biogeography of marine giant viruses - where do they live and why? (1/6)
- We focused on prasnoviurses infecting Micromonas (MpV), a picoeukaryote genus distributed from poles to tropics. We explored the distribution of isolated MpV-s in Tara datasets and highlighted that temperature is the main descriptor of their community composition. (2/6)
- By reconstructing virus phylogeny, we found that MpV-s were clustered into cryophile groups, growing mainly at low temperature below 10°C, or cryo-mesophile groups, growing from cold to more than 20°C. (3/6)
