Niche modelling and aDNA reveal increasing prevalence of black horses in post-glacial forests, suggesting they became increasingly adapted to these habitats.
Long-term grassland and forest experiments reveal that temporal strengthening in biodiversity functioning relationships is mainly driven by increases in functioning in high-diversity communities.
Despite recent IUCN downgrading of the giant panda’s conservation status from ‘endangered’ to ‘vulnerable’, new GIS and remote sensing data reveal panda habitats to cover less area and be more fragmented than previously.
Theory predicts that gene flow hinders local adaptation, unless it is coupled with habitat choice. Here, the authors show that dispersal with habitat choice favours local adaptation in ciliate microcosms.
Plants can induce anti-herbivore defences through the synthesis of proteins that reduce feeding. Induction of these defences in tomato plants also reduces herbivore damage by promoting cannibalism among insect larvae.
In rangeomorphs of the Ediacaran period, first appearing 571 million years ago, growth of branch internodes declined as their surface area decreased relative to volume, suggesting nutrient-dependent growth.
Co-mapping the incidence of worker reproduction and queen pheromone chemical composition on a phylogeny of stingless bees reveals no association between queen hydrocarbon profiles and worker reproduction.
In a semi-naturalistic ‘Metatron’ experiment, a rise of 2–3 °C causes a reduction in gut microbiome diversity of over one-third in an ectotherm, the common lizard (Zootoca vivipara).
Humans and great apes show left-cradling bias but it is unclear how widespread this bias is. Here, the authors show lateralization in interactions between an infant and its mother in 11 marine and terrestrial mammals, which suggests that lateralization has an ancient evolutionary history.
