  • Islands may impose a distinct set of selective pressures, leading to the repeated evolution of certain traits. Here, Sayol et al. compare brain sizes of more than 1900 bird species in a phylogenetic context, finding a consistent trend for in situ evolution of increased brain size in island birds.

  • Environmental variation has been hypothesized to favour the evolution of large brains capable of adjusting behaviour to changing circumstances. Here, Sayolet al. find that across more than 1200 bird species, species with relatively large brains are indeed associated with more variable habitats.

  • Penuelas et al analyse foliar concentrations of nutrients in the main tree species of European forests using data collected over 30 years, together with changes in atmospheric CO2 levels, N and S deposition and climate. They find that foliar concentrations of N, P, K, S and Mg have decreased in central and southern Europe, with implications for forest ecosystems.
