Genetic variation in the emblematic Puya raimondii (Bromeliaceae) from Huascarán National Park, Peru

A study on the emblematic Puya raimondii, a giant Andean bromeliad found in Huascarán National Park, Peru, reveals significant genetic differentiation among its populations despite long-distance dispersal. Researchers analyzed 60 individuals using AFLP profiles with four selective primer combinations, detecting 172 bands, of which 79.1% were polymorphic loci. The findings suggest that gene flow occurs between populations located in different mountain systems, indicating long-distance dispersal capabilities. This insight is crucial for developing effective conservation strategies to preserve the genetic diversity of this iconic species, emphasizing the need to account for exchange between geographically distant populations.
