Abstract excerpt

Self-fertilization and inbreeding depression (δ) are expected to co-evolve, particularly during range expansion, yet few studies have examined this dynamic in tropical trees, which could be relevant for their conservation. We investigated the mating system of Pericopsis elata (Fabaceae), an endangered timber species with a fragmented distribution in Central Africa comprising two distinct genetic clusters: the...
