Both within and between hosts, the key factor guiding whether increasing treatment strength will increase or decrease antibiotic resistance is whether inter-strain competition is effective, not whether it is present.
Unfair competition, in which a phosphatase and a phosphoprotein inhibitor/substrate mutually sequester each other from competing substrates and enzymes, is a conserved mechanism for the control of PPP family phosphatases.
Multistability and regime shifts are common and species diversity is high in microbial communities when nutrient supplies are balanced and competing species have different stoichiometries of essential nutrients.
Genome wide association analyses in a wild-derived Drosophila melanogaster population uncover extensive variation in cuticular hydrocarbon composition, which may present a target for natural selection and adaptive evolution.
Quantitative analyses of yeast P bodies reveals a small number of highly concentrated proteins and many weakly concentrated proteins, suggesting that the compartments are compositionally simpler than previously thought.
In a minimalistic, generic model of competitive communities in which evolution is constrained by life-history trade-offs, stable biodiversity emerges with species adapted to different functional niches.
