Novel features related to turgor loss adjustment and higher ability to modulate leaf-construction costs could improve A. altissima fitness in its invaded range.

Abstract

Phenotypic plasticity has been recently proposed to play an important role in invasion process. More precisely, phenotypic plasticity of alien invasive species could be higher in their exotic rather than native habitat, probably because of the release from biotic or abiotic constraints. In this paper, several plant functional traits were analysed on Ailanthus altissima (Mill.) Swingle, a highly invasive species in Europe, aiming at providing a comparison among key functional traits measured on individuals growing in their native habitat and to test if values of functional traits and their related plasticity are higher in exotic habitats. Our analysis pinpointed that variability of functional traits in the native habitat was mainly driven by different irradiance, temperature and evaporative demand of the studied sites, in accordance to the traits trade-offs in the Leaf Economic Spectrum. Physiological traits related to drought tolerance were different between native and exotic habitats. In the native one, A. altissima relied on osmoregulation processes to adjust leaf turgor loss point (Ψtlp), as the osmotic potential at full turgor (π0) were lower in drier sites. In the exotic habitat, individuals in drier sites had similar π0 but lower wall elasticity (ε), suggesting that leaves had thinner cell walls. Moreover, plasticity in specific leaf area and ε were higher in the exotic habitat. The novel features related to Ψtlp adjustment and the higher plasticity in traits related to leaf-construction costs could increase A. altissima fitness in response to different environmental conditions in its invasive range.
