    Turning induced plasticity into refined adaptations during range expansion

    Data collection and sample sizes We collected 10–15 ornamental feathers (3–5 from each of the three ornamental areas—crown, breast, and rump, Fig. 1 in ref. 59) from 1196 free-living adult male house finches. To minimize temporal variation of feather wear and standardize sampling across long-term study populations, we only used feathers sampled during May–June from 2008 […] More

    A comparative study on the micro-surface characteristics at black shale initial oxidation stage

    In natural systems, the black shale oxidation process is usually involved in multiple factors, such as chemical and biological mechanisms29,36. Previous studies have shown an effective pyrite oxidation ability presented in biological system such as A. ferrooxidans22, but few investigations have discussed its direct relationship to black shale oxidation. Considering the oxidation process initiated at […] More

    Excess sulfur and Fe elements drive changes in soil and vegetation at abandoned coal gangues, Guizhou China

    Study area The research was conducted in Huaxi District (106°27′–106°52E, 26°11′–26°34′) in the middle of Guizhou province. Huaxi District is located on the eastern slope of the Yunnan–Guizhou Plateau and has a subtropical monsoon humid climate, though it is also affected by its high altitude (the average altitude is 999 m), being cool in summer and […] More

    The demographic decline of a sea lion population followed multi-decadal sea surface warming

    All the analyses described below were based on algebraically explicit Bayesian regression models52,53, whose parameters of interest were estimated as samples from their posterior distributions through a Markov Chain Monte Carlo procedure, implemented in the language Just Another Gibbs Sampler (JAGS)54 in R55. This approach avoids the loss of information through the propagation of uncertainty […] More
