Parallel evolution of mutational fitness effects over 50,000 generations

The study examines how mutation fitness effects change over 50,000 generations in E. coli, finding parallel evolution of mutation costs and increased essentiality without altering the overall fitness landscape distribution.

Small subsets of highly connected taxa predict compositional change in microbial communities

The paper shows that highly connected taxa in microbial communities predict compositional changes better than all taxa, and that community connectivity reduces compositional turnover.

Cohesion: A method for quantifying the connectivity of microbial communities

The paper introduces a metric called cohesion to quantify microbial community connectivity and shows it predicts community dissimilarity better than environmental data alone.
