The workshop was held as a commitment of TREEBREDEX coordinated action (coord. Dr. Luc Pâques, INRA Orléans). With more than 50 participants, and relevant invited speakers such as Carl Schlichting (Univ. Connecticut), Fernando Valladares (CSIC), Susan Dudley (Mc. Master Univ.) and Partricia Givert (CNRS), the workshop facilitated interesting discussions and increased the knowledge on:

• Relationships between phenotypic stability and phenotypic plasticity
• Distinctions between plasticity of populations and genetic variability of populations
• Genetic variation of phenotypic plasticity
• Epigenetic memory as part of adaptive plasticity
• Quantification of the environmental variables in genotype x environment studies of plasticity
