Genetic conservation strategies of endemic plants from edaphic habitat islands: The case of Jacobaea auricula (Asteraceae)

Conservation genetics is a well?established and essential scientific field in the toolkit of conservation planning, management, decision?making. Within its framework, phylogeography allows definition strategies, especially threatened endemic plants. Gypsum salt-rich outcrops constitute model example an edaphic island-like habitat contain rare species, many them threatened. This case Jacobaea auricula, Iberian gypsohalophytic species with biological, ecological, interest. Genetic-based criteria were used to preserve highest possible percentage species' genetic pool as well dispose set genotypes for translocation and/or reinforcement planning degraded populations. Relevant Genetics Units (RGUCs) selected situ planning. As complementary ex measure, optimal contribution populations maximize within each cluster was calculated. To maximum diversity AFLP bands possible, eight RGUCs selected; design included twenty-one populations, gathering all haplotypes ribotypes. Our proposal J. auricula would improve implementation future measures, plants from islands.
