Holm oak decline is determined by shifts in fine root phenotypic plasticity in response to belowground stress.

Climate change and pathogen outbreaks are the two major causes of decline in Mediterranean holm oak trees (Quercus ilex L. subsp. ballota (Desf.

Photoprotective compounds as early markers to predict holm oak crown defoliation in declining Mediterranean savannahs.

Dehesas, human-shaped savannah-like ecosystems, where the overstorey is mainly dominated by the evergreen holm oak (Quercus ilex L. subsp. ballota (Desf.

Greater phylogenetic distance from native oaks predicts escape from insect leaf herbivores by non-native oak saplings.

Premise: Non-native plant species have been hypothesized to experience lower herbivory in novel environments as a function of their phylogenetic distance from native plant species. Although recent work has found support for this prediction, the plant traits responsible for such patterns have been largely overlooked.

Methods: In a common garden experiment in northwestern Spain, we tested whether oak species (Quercus spp.
