Abstract

The species Zelkova abelicea (Lam.) Boiss., an endemic of Crete, constitutes a relict of tertiary period and has a disjuncted distribution across the island’s mountain ranges. This study aims to investigate nutrient concentration and biometric characteristics of Z. abelicea leaves from different sites in Crete, where the species has been recorded. In particular, the NPK stoichiometry and biometric characteristics such as leaf area (LA), leaf perimeter (LP), internal perimeter (IP), number of teeth (NT), tooth area (TA), leaf length (L) and leaf width (W), as well as selected ratios of the above. Results indicate that NPK stoichiometry and leaf biometric characteristics show significant phenotypic plasticity, which may be related to a mechanism of persistence during climate and other environmental changes that took place from the Tertiary until now. Plasticity as part of such a mechanism may be key element for persistence in the hot, dry, oligotrophic Mediterranean environment. This study constitutes part of a wider effort for the research of all species of the genus Zelkova at the global level, which aims at a comprehensive understanding of basic ecosystem-level functions, with ultimate goal the contribution to the conservation of these species.
