We rely on healthy soil microbial communities to support ecosystem functioning and plant growth, but what happens when soils are exposed to multiple environmental stressors simultaneously? Spoiler: it's not good doi.org/10.1093/isme...

Fungicide and warming interact to reduce soil ecosystem functioning

Abstract. Soil microbial communities are essential to the functioning of their ecosystems, providing vital services such as plant growth promotion and bior

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.

Inferring single-cell heterogeneity of bacteriophage lysis-associated life-history traits from population-scale dynamics

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

Eye-opening work by @olimeacock.bsky.social (former postdoc, now PI in Sheffield). He presents an exact mapping from steady-state consumer-resource to generalized Lotka-Volterra models, revealing that cross-feeding can lead to competition for other limiting resources. Feedback pls!

New preprint from @saramitri.bsky.social and me: tinyurl.com/3dsjnm4d The headline result - we derive a general way to connect mechanistic ecosystem models to the gLV equation. This reveals that strengthening cooperative mechanisms can make effective gLV interactions increasingly competitive. Weird!

PLEASE SHARE. PhD Opportunity with me, Ben Raymond and Jan Engelstaedter and Andrew Letten at University of Queensland. Experimentally testing mechanisms of how temperature may change selection and spread of AMR in E. coli. Coupled with some advanced modelling and sequencing. 🧪🦠 #microsky
