Bacteriophage continue to have so much to teach us. It's in our interest to understand how they work and impact human & environmental health. New joint work led by @mariandm.bsky.social & @rantahan.bsky.social inferring single-cell latent period & burst size heterogeneity from population dynamics.

Theory-guided experiments reveal single-cell heterogeneity of lysis-associated bacteriophage traits from population scale data.

Viruses are highly abundant in the oceans, but there is one place you won't typically find them: in global ocean ecosystem models... until now. Introducing "vDarwin", an explicit integration of viruses into the MITgcm/Darwin global ecosystem framework: www.biorxiv.org/content/10.6... a 🧵
Integration of a model of viral lysis, shunt and shuttle in a large scale ocean circulation model. (A) Schematic of the large scale ocean circulation model (MITgcm): major surface ocean circulation patterns and the schematic of the advection/diffusion are represented. Note that vertical grid spacing increases with depth (i.e., layers become thicker). (B) Simplified ecosystem represented in the study. For simplicity nitrogen remineralization to nitrite and nitrate and mortality fluxes to DOM and POM are not represented. (C) Schematic of the vDarwin ecosystem model integrated in the large scale circulation model. It represents a simplification of the ecosystem presented in (B) assuming that N is the limiting nutrient. It includes the growth of a single phytoplankton type, viral lysis, zooplankton grazing, the viral shunt and shuttle and remineralization (note that remineralizing bacteria are not explicitly represented).
