Response of native (Quercus robur L.) and alien (Quercus rubra L.) species to water stress and nutrient input in European temperate ecosystems.

ABSTRACT: Drought and nutrient-poor soils can increase the invasive potential of non-native species, further changing the ecosystems they invade. The high adaptability of these alien species, especially in their efficient use of resources, improves their resilience against abiotic stress. Here, we evaluated the response of the North American Quercus rubra L. (RO) and the European Quercus robur L. (EO) oak species to drought and nutrient scarcity as single and combined factors. Both species were grown under well-watered or alternating short dry-wet phases, with or without the addition of phosphorous (P) and labelled nitrogen (N). Leaf gas exchanges and stem water potential were measured; moreover, leaf chemical characterization was carried out. Under concurrent low fertility and drought, both species
