Drought affects the performance of native oak seedlings more strongly than competition with invasive crested wattle seedlings

[EN] Two of the most important processes threatening vulnerable plant species are compet-itive displacement by invasive alien species and water stress due to global warming.Quercus lusitanica,an oak shrub species with remarkable conservation interest, couldbe threatened by the expansion of the invas...
