  • 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.
