    Plasmids facilitate the evolution of antibiotic resistance but little is known about bacteria–plasmid evolution. Here, the authors show that when bacteria adapt to one plasmid, they become generally permissive to plasmid carriage.

    The mechanisms underlying drought-induced tree mortality are not fully resolved. Here, the authors show that, across multiple tree species, loss of xylem conductivity above 60% is associated with mortality, while carbon starvation is not universal.

    Analysing data from more than 1,000 sites globally, the authors show that palaeoclimatic legacies explain a greater amount of variation in bacterial community richness and composition than current climate.

    The position of limbs varies across vertebrates. Here, the authors show that GDF11 is a key factor in the integration of sacral vertebrae and hindlimb positioning and underlies diversification of the hindlimb position in vertebrates.

    Transfer of mobile genetic elements between bacteria is widespread, facilitating adaptation. Here, the authors show that horizontal gene transfer is inhibited in soil bacterial communities undergoing positive selection for mercury resistance.

    Mobile genetic elements can confer antibiotic resistance on their bacterial hosts. However, they are often costly leading to conflict with the host chromosome, which can drive intragenomic coevolution and consequent modulation of resistance.

    Estimates of stomatal conductance are important for models of crop and ecosystem water and carbon flux. Here, data from temperate tree species show interspecific variation in stomatal function that can be accounted for to make models more accurate.

    The use of genomic data to reconstruct phylogenetic relationships is powerful but challenging. Here, the authors develop a bioinformatics pipeline and use phylogenomic datasets to reconstruct the evolutionary relationships of jawed vertebrates.

    Phylogenetic and biogeographic modelling show that high-latitude Antarctic nearshore habitats have been an evolutionary sink for species diversity of notothenioids, which dominate teleost fish diversity in the Southern Ocean.

    Sperm morphology is remarkably variable yet its genetic architecture is poorly known. Now, sperm morphology variation in zebra finches is shown to be largely explained by an inversion polymorphism on the Z chromosome acting as a supergene.

    It is unclear how variation in sperm traits is maintained in nature. Here, the authors show that an inversion on the Z chromosome of zebra finches affects sperm morphology and fertilization ability and suggest that overdominance maintains the inversion polymorphism.

    The authors predict biodiversity loss under potential future agricultural change. Agricultural expansion threatens species richness and abundance worldwide (up to one-third in some areas), often with little overlap between protected areas and high-risk expansion areas.

    Little is known about the evolution of neural induction mechanisms in chordates. Here, the authors show that the dorsal blastopore lip of the cephalochordate amphioxus is homologous to the vertebrate dorsal organizer and that it promotes neural induction through Nodal–Activin signal.
