Variabilidad intraespecífica de rasgos y funcionamiento ecosistémico en condiciones de cambio ambiental: líquenes epífetos de bosques Mediterráneos como caso de estudio

This project focuses on assessing intraspecific variability of functional traits in lichens, which is key to their adaptation to changing conditions and to ecosystem functioning. Since this variability occurs across multiple spatial, temporal, and biological scales, identifying where it is maximized can better guide the study of ecological patterns and processes. Moreover, trait covariation may reflect adaptive responses and ecosystem-level effects. Our objective is to evaluate the variation and covariation of traits in epiphytic lichens from Mediterranean forests along environmental gradients (climate, fragmentation, and management) and across different spatial scales. Intraspecific variability may arise from phenotypic plasticity and/or genetic diversity, yet their relative contribution under global change remains unclear. Therefore, we aim to investigate the genetic basis of phenotypic variability and its relationship with global change drivers by analyzing population genetic variability and its association with environmental variables.
