Key message Significant changes in root biomass allocation, water transport and leaf structure allow P. pallida seedlings to overcome El Niño extreme events. Abstract The North Peruvian dryland forests face long droughts which promote adaptive mechanisms to cope with low water availability. However, the impact of the El Niño South Oscillation on these forests provides a unique set of conditions...
Aims To assess the fertility island effect of Prosopis pallida in the North Peruvian dry forests and analyze if it is influenced by tree size and structural and/or chemical leaf traits. Methods We measured the soil nutrient concentrations under and outside the tree canopy in five populations that differ in mean annual temperature and annual rainfall in North Peru. We also measured tree size (height,...
Background and aims Root traits play a critical role in plant resource-use strategies and ecosystem functioning, but there is great controversy regarding their identity and functionality in different dimensions of belowground functional variation. Here, we explored the level of covariation among a suite of key root traits (i.e. specific root length, root dry matter content, diameter and density) as...
