    Extinction risk and conservation of the world’s sharks and rays

    Nicholas K Dulvy et al.
    One-quarter of the Chondrichthyes have an elevated risk of extinction, mainly as a result of overfishing.

    Neural network of social interaction observation in marmosets

    Justine C Cléry et al.
    The brain network associated with social interaction observation involves large part of the frontal cortex and parietal areas in marmosets.

    Experimental and observational studies find contrasting responses of soil nutrients to climate change

    ZY Yuan et al.
    Experimental manipulations and environmental gradients, the two common-used approaches, are not at all comparable for predicting the impacts of climate change on nutrient cycling.

    Epigenetic conservation at gene regulatory elements revealed by non-methylated DNA profiling in seven vertebrates

    Hannah K Long et al.
    Islands of non-methylated DNA are shown to perform a similar epigenetic role in many different vertebrate species.

    Repeated losses of PRDM9-directed recombination despite the conservation of PRDM9 across vertebrates

    Zachary Baker et al.
    PRDM9 is widely conserved across vertebrates yet has been lost numerous times, as has its role in directing meiotic recombination.
    1. Ecology

    Regularities in species’ niches reveal the world’s climate regions

    Joaquín Calatayud et al.
    Similarities in climatic niches of terrestrial vertebrates indicate the Earth's climate regions, which differ among groups and from previous plant-based climate classifications.
    1. Neuroscience

    Social observation enhances cross-environment activation of hippocampal place cell patterns

    Xiang Mou, Daoyun Ji
    Place cells associated with track-running are activated in rats staying in a nearby box while another rat running on the track, suggesting that social observation facilitates spatial memory representations.
    1. Neuroscience

    Conservation of preparatory neural events in monkey motor cortex regardless of how movement is initiated

    Antonio H Lara et al.
    Voluntary movements are preceded by a temporally flexible preparatory neural process that is present regardless of whether movement is initiated rapidly or thoughtfully.

    Travel fosters tool use in wild chimpanzees

    Thibaud Gruber et al.
    Travel has a major influence on tool use in wild chimpanzees, suggesting that tool use reduced travel costs during hominid evolution.
    1. Ecology

    Mammal communities are larger and more diverse in moderately developed areas

    Arielle Waldstein Parsons et al.
    Citizen science camera trapping showing suburban and wild areas maintain similar levels of mammalian diversity and relative abundance, challenging conventional thoughts about the impacts of urbanization on wildlife.
