Plasmids drive bacterial adaptation, but how their diversity arises has remained unclear. Here, they show that in Staphylococcus aureus, mobile genetic elements repeatedly fuse and delete plasmids, re...

Resource supply is generally considered a dominant driver of microbial diversity. Here, using a four-species bacterial consortium, we asked whether...

Over the past century, the generalized Lotka–Volterra (GLV) model has grown from a mathematical curiosity to a cornerstone of theoretical ecology. Here we celebrate the enduring legacy of Lotka and Vo...

Lund University welcomes applicants with different backgrounds and experiences. Gender equality, equal opportunities and diversity are fundamental principles in all parts of the University’s activit

Community ecology has developed a rich and increasingly diverse body of theory, but its rapid expansion has outpaced efforts to compare and synthesize competing frameworks. As a result, semantic ambig...

<p>There is something indescribably intimate about the act of interrupting one’s reading, the act of marking one’s place in a book, a subtle gesture t

In cell biology, computational models of biological systems range from minimal representations with a handful of parameters to whole-cell simulations tracking thousands of molecular species across a c...

A central puzzle in the evolution of individuality is the origin of heredity. Egalitarian transitions integrate formerly independent replicators into a higher-level individual, but this requires the c...

Abstract. Evolutionary “fitness” is operationalized in many different ways in models. Its role is to quantify that which is favored by natural selection. G

All organisms defend against viral infections through active immunity mechanisms that clear the virus or population-level mechanisms that cause regulated cell death. Recent research increasingly shows...

Abstract. In 2006, a manuscript appeared with a provocative title: “Darwinian evolution can follow only very few mutational paths to fitter proteins.” Twen

Nature Microbiology, Published online: 29 June 2026; doi:10.1038/s41564-026-02386-4By taking into account the impacts of species presence, absence and potential interactions, synthetic soil microbial consortia are designed to degrade the toxic environmental contaminant bisphenol-A.

Nature Communications - Beyond resistance and tolerance: rethinking evolutionary responses to antibiotics from the perspective of individual bacterial cells

Les professeures Sara Mitri, au Département de microbiologie fondamentale, et Tanja Schwander, au Département d’écologie et évolution de l’Unil, reçoivent chacune un ERC Advanced Grant de l’European R...

Abstract. Phage therapy offers an alternative to antibiotics for treating multidrug-resistant infections. Plasmid-dependent phages (PDPs) are promising the

Abstract. Many microbiological outcomes are shaped by the determinants of community composition, including the factors that allow pathogens to invade healt
