Longitudinal data on gut microbiomes of wild baboons show that microbial communities are highly individualized, despite shared diet and environment within primate social groups.
Whole-genome sequencing and comparative omics analyses highlight recent and parallel paths to adaptive evolution involving expansions in zinc-binding proteins in the genomes of diverse cold-adapted algae.
Examining the evolutionary history of ungulate migration shows that this behaviour has evolved multiple times in response to grassland expansion and increased seasonality of resources.
Analysis of sediment and pore water from three seagrass meadows around the world reveals an unexpected accumulation of labile carbon in the marine rhizosphere, explained by sediment chemistry.
A computational method that negates the need to directly measure species interactions provides evidence in support of classic theory, stating that microbial communities with higher diversity remain stable as long they have low complexity and weaker interactions.
Simultaneous evolution of vaccine-induced immune escape and virulence leads to different evolutionary end points, depending on the type of vaccine-induced protection.
An analysis of phenotypic skew — the asymmetrical distributions of traits — explores how it can bias estimates of inheritance and selection, and how to correct for those biases.
Combining pantropical fish community surveys with bioenergetic models has revealed the global distribution of reef-fish ecosystem functions, and that trade-offs linked to demographic and trophic structure prevent any community from maximizing all functions simultaneously.
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.
