A framework to experimentally traverse the large space of functionally neutral variants in a toxin–antitoxin protein complex reveals insights on evolvability and entrenchment of molecular interactions.
Analysis of the dynamics of transposons that encode resistance to different antibiotics shows that the movement of genes under positive selection from the chromosome to mobile genetic elements such as plasmids can be beneficial in bacteria. Once integrated into plasmids, these genes can spread by horizontal gene transfer.
Experimentally manipulating precipitation levels in a plant–soil feedback experiment reveals changes to the interactions between plants and soil microbes that render community dynamics less predictable under wetter conditions.
Taking advantage of natural variation present in six populations of wild orangutans, a new study correlates population density with multiple facets of individuals’ vocal phenotype and demonstrates that sociality influences vocal plasticity in great apes.
Population genomic and phylogenomic analyses of Atlantic cod provide new insights into the origin and maintenance of supergenes and highlight the role of recombination and structural variants.
An exceptionally large species of sauropod titanosaur from the Late Cretaceous of northern Spain provides insight into changing diversity dynamics of titanosaurs over time, and sheds light on faunal turnover and migration.
Rapid morphological evolution in early echinoderms was later outpaced by increases in ecological diversification, indicating the phylum exhibited morphological volatility and ecological constraints at its origin.
A landscape-level natural experiment in free-ranging pumas reveals how changes in hunting pressure alter viral evolution and infection dynamics through indirect effects on puma population size, demography and behaviour.
Contrary to previous studies, an analysis of 7,000 plant and animal species shows that species size is unrelated to changes in their population abundance.
Analysis of population genomic and transcriptomic data of flies and humans shows that species-specific mutation biases and common selective forces have collectively shaped the early evolutionary phase of duplicated DNA segments that overlap with coding genes.
Spatiotemporal modelling of tumours detects at least two distinct models of cancer evolution and reveals the influence of necrosis in enhancing the metastatic potential in both models.
Combined mutation rate estimation and reverse ecology sheds light on the forces shaping population size of Prochlorococcus, a major bacterial carbon sink.
A global synthesis of plant traits finds that climate and soil variables explain two key axes of trait variation, offering a new framework to understand how the environment shapes plant form and function.
A macroecological view suggests some global drivers of language endangerment and continuity, but a focus on individual languages will be important to stem the tide of language loss.
Two analyses of long-read sequencing show that the Winters sex-ratio distorter of Drosophila has been a part of a recent gene family expansion, coupled to the appearance of suppressors, in a genomic arms race driven by satellite DNA.
The strength of functional diversity effects on forest productivity increases over time, highlighting the key role of multi-species tree communities in long-term restoration initiatives.
