    Combining phylogenetic, morphological and environmental data on range overlap among 1,115 pairs of bird species, the authors show that coexistence is best explained by a model integrating both dispersal-assembly and niche-assembly processes.

    Analysing data from the Tara Oceans expedition, the authors show that the abundance distributions of non-dominant marine microbial eukaryotes are characterized by a power-law decay, the exponent of which varies by less than 10% across the global ocean.

    It is unclear whether biodiversity evolves gradually or in rapid bursts associated with speciation. Here, the authors show that patterns of avian trait divergence are not gradual and that early pulses of trait divergence promote subsequent transitions to sympatry.

    Screening reveals that the bacteriophage-encoded enzyme S-adenosylmethionine (SAM) hydrolase rescues isoleucine-deficient Escherichia coli by reducing bacterial SAM levels, resulting in derepression of the promiscuous bacterial enzyme MetB.

    Data from 42 chronosequence sites show a geater abundance of legumes in seasonally dry forests than in wet forests, particularly during early secondary succession, probably owing to legumes’ nitrogen-fixing ability and reduced leaflet size.

    Loss of eyes is a common feature of cave-adapted animals such as the blind cave morphs of Astyanax mexicanus. Here, the authors show that DNA methylation mediates eye-specific gene repression and globally regulates early eye development in A. mexicanus.

    Division of labour is common in social groups from microbes to animals. Here, the authors show that natural selection favours extreme specialization, suggesting that division of labour may drive major evolutionary transitions.

    Most work on phenological mismatch has focused on temporal trends only. Here, the authors analyse trends in spatial and temporal mismatch between trees, caterpillars and birds in the UK, and find delayed phenology of all species with increasing latitude and little spatial variation in the magnitude of mismatch between caterpillars and birds.

    Fitness landscapes describe the fitness of each genotype in a given environment. Here, the authors determine fitness landscapes of a yeast tRNA gene in four environments and show simple genotype-by-environment patterns that can easily be extrapolated to a new environment.

    The acetyl-CoA pathway is the most ancient CO2 fixation pathway in nature. Here, the authors show that metals selectively reduce CO2 to the intermediates and end-products of the acetyl-CoA pathway, which is consistent with a prebiotic origin of this pathway.

    The fungal pathogen Hymenoscyphus fraxineus is killing European common ash trees. Here, the authors sequence the genome of H. fraxineus and show that European populations were founded by two divergent haploid individuals introduced from Asia.

    The ability to evolve resistance to the antibiotic ceftazidime is shown to vary across the Pseudomonas genus because the AmpR global transcriptional regulator potentiates evolution. Blocking this pathway can eliminate pathogenic strains before they evolve resistance.

    Many organisms can modify habitats for their own benefit, but some may also do so in non-beneficial ways. Here, the authors report an extreme example in soil bacteria in which modification of environmental pH at high population densities leads to population extinction.

    Trade-offs are common during evolutionary innovation. Here, the authors show that multicopy plasmids allow coexistence of the ancestral and evolved alleles in the TEM-1 β-lactamase system, helping bacteria to escape evolutionary constraints imposed by trade-offs.

    Virtual manipulation of the archaic hominin specimen Kabwe 1’s browridge and biting simulations reveal a limited spatial and biomechanical role, opening up the possibility that the hominin supraorbital region was co-opted for social signalling after facial reduction and morphological changes in the frontal bone.
