Treating color patterns in a geometric morphometrics framework reveals rapid rates of color evolution that are explained by a combination of intrinsic organismal features (color variation among patches) and geography within a cosmopolitan radiation of birds.

Greater mouse-eared bats prefer to hunt large ground insects despite high failure rates, but switch to smaller, easily caught flying insects in response to environmental changes.

High-throughput measurements of simplified bacterial communities find that when multiple species jointly inhibit a focal species of interest, their individual effects do not add up, but are dominated by the strongest single-species effect.
The mathematical model incorporating new parameters explains multimodal distributions in escape direction (i.e., multiple preferred escape trajectories), which are previously observed in various animal taxa.

The global spread of antibiotic resistance could be due to a number of factors, and not just the overuse of antibiotics in agriculture and medicine as previously thought.
Longstanding eco-evolutionary theories are tested using shotgun metagenomic data from the human gut microbiome, showing links between community diversity and the evolutionary trajectory of a focal species within the community.
Secondary metabolites rocaglates produced by plants lead to a plant‒fungus tug-of-war, utilizing unique amino acid substitutions in eIF4A, a target of the compounds.
Mobility across ecological contexts and continents is more important to describe the worldwide spread of bacterial resistance to aminoglycosides (a family of antibiotics), than the consumption of aminoglycosides itself.
