Conservation genetics is a well-established and essential scientific field in the toolkit of conservation planning, management, and decision-making. Within its framework, phylogeography allows the definition of conservation strategies, especially in threatened endemic plants. Gypsum and salt-rich outcrops constitute a model example of an edaphic island-like habitat and contain rare and endemic species, many of them threatened. This is the case of Jacobaea auricula, an Iberian gypsohalophytic species with biological, ecological, and conservation interest. Genetic-based criteria were used to preserve the highest possible percentage of the species' genetic pool as well as to dispose of a set of genotypes for translocation and/or reinforcement planning of degraded populations. Relevant Genetics Units for Conservation (RGUCs) were selected as in situ conservation planning. As a complementary ex situ measure, the optimal contribution for the populations to maximize the genetic pool within each genetic cluster was calculated. To preserve the maximum genetic diversity and the highest percentage of rare AFLP bands possible, eight RGUCs were selected; the ex situ conservation design included twenty-one populations, gathering all haplotypes and ribotypes. Our genetic conservation proposal of J. auricula would improve the implementation of future genetic conservation measures, as a species model of endemic plants from edaphic habitat islands. 2021-06-14T06:51:46Z 2021-06-14T06:51:46Z 2021-04-24 info:eu-repo/semantics/article Javier Bobo-Pinilla, Esteban Salmerón-Sánchez, Juan Francisco Mota, Julio Peñas, Genetic conservation strategies of endemic plants from edaphic habitat islands: The case of Jacobaea auricula (Asteraceae), Journal for Nature Conservation, Volume 61, 2021, 126004, ISSN 1617-1381, [https://doi.org/10.1016/j.jnc.2021.126004] http://hdl.handle.net/10481/69142 10.1016/j.jnc.2021.126004 eng http://creativecommons.org/licenses/by/3.0/es/ info:eu-repo/semantics/openAccess Atribución 3.0 España Elsevier
