Neutral tagging and detailed analysis of bacterial growth kinetics can quantify the mechanisms of colonization resistance in differently colonized animals.

A large-scale analysis of Staphylococcus aureus within-host evolution based on a comprehensive catalogue of bacterial genetic variation reveals an excess of genome degradation signatures in infecting strains and new genetic loci of clinically relevant adaptation.

The characterization of ancient B19V and HBV genotype A4 viruses circulating during Colonial epidemics provides new insights into the pathogens that were introduced to the Americas after the European colonization.
The cessation of major anthropogenic disturbances since European colonization in the forests of central Africa leads to a canopy closing, and to the disappearance of certain light-demanding tree species.

Variation in migration can evolve rapidly and traits that comprise this behaviour may be determined by standing variation at a few regulatory regions that are not common across taxonomic groups.

Social hierarchies resulting from the European colonization of the Americas stratified the population structure, leading to ancestry-related assortative mating and sex bias patterns that can be inferred from the genomes of the populations across the continent.

Reconstruction of transmission pathways of methicillin-resistant Staphylococcus aureus using multiple genomes per host reveals great variation in the size of the transmission bottleneck and limited evidence for body site/phylogeny association.
Arbuscular mycorrhizal fungi-induced hydroxy- and carboxyblumenol C glycosides accumulate in plant shoots and allow for facile high-throughput screening for functional plant-AMF associations.

The mathematical modeling approach disentangles the impacts of the COVID-19 pandemic on antibiotic resistance in Streptococcus pneumoniae in the community setting and identifies the three most plausible driving mechanisms responsible for the observed trends in invasive isolates and pneumococcal carriage.
The chestnut blight fungus has successfully established an intermediary, diverse European bridgehead population, giving rise to a highly invasive clonal lineage spreading across southeastern Europe.
