The complex interactions between adaptive traits, mating system, demography and past species history shape current levels and distribution of genetic diversity. In the species-rich, highly diverse rainforest ecosystem, several (alternative) mechanisms can lead to the observed patterns. The genetics team at ECOFOG uses model rainforest tree species with contrasted life-history traits, ecological preferences and demographic strategies, to tear all these factors apart and to shed light on the evolutionary forces that determine population structure and species distribution

Our approach combines the use of neutral molecular markers, the analysis of signatures of selection in candidate genes and the analysis of quantitative adaptive traits in controlled conditions. The foundations of our strategy are in an interdisciplinary approach, obtained through collaborations within and beyond our Research Unit.

Current activities include:

• Reconstructing the phylogeographic history of several widespread tree species in South America
• Studying the genetic structure of populations of Jacaranda, Eperua, Virola and Dicorynia populations and the genetic consequences of regeneration
• Identifying the genetic factors leading to the adaptation to water availability/excess
