The objective of the IVEP team is to develop an integrative approach to investigate the determinants of phenotypic plasticity across different biological scales. Phenotypic plasticity is the capacity of a given genotype to produce a diversity of phenotypes in response to variations in the environment and represents one of the most important ways by which organisms adaptively respond to the environment. The IVEP team ambitions to investigate how biological entities, being cells or individuals, integrate environmental changes to produce adaptive responses and it also aims at examining how phenotypic plasticity emerges from interactions among its underlying components.
