priority populations

The Atlantic Rainforest in Brazil is currently comprised of small fragments due to the history of conversion and degradation in the last five centuries. The rainforest trees, Ocotea catharinensis, O. odorifera and O. porosa have been heavily harvested because of the high economic value of their timber and essential oils. Their respective habitats have undergone substantial reduction in area due to continuing anthropogenic pressures. As a consequence, these species have suffered large declines in population size and are now considered to be potentially vulnerable to extinction. This study investigated the patterns and levels of genetic diversity and inbreeding of these species using eight microsatellite markers in order to define priority populations for conservation management actions focusing on population enhancement and ex situ germplasm collections. High genetic diversity was found for each of the species with moderate genetic differentiation among populations. Most populations displayed significant inbreeding and isolation by distance. The results provide important information to choose priority populations for both in situ and ex situ conservation measures.
