The evolution of reduced facilitation in a four-species bacterial community

This study evolves four bacterial species in isolation and community to examine how positive interactions influence evolution, finding weakened interactions and resource specialization.

Microbial invasion of a toxic medium is facilitated by a resident community but inhibited as the community co-evolves

The paper shows that microbial invaders can more easily colonize toxic environments with existing communities but face greater resistance when communities co-evolve.

Toxicity drives facilitation between four bacterial species

The paper shows that toxicity in Metal-Working Fluids (MWF) drives positive interactions between four bacterial species by facilitating their survival and degradation of MWF.

Phage efficacy in infecting dual-strain biofilms of Pseudomonas aeruginosa

This study investigates how strain diversity in Pseudomonas aeruginosa biofilms affects phage efficacy, finding that spatial structure provides refuge and reduces resistance evolution.
