    A genetic approach to spanish populations of the threatened Austropotamobius italicus located at three different scenarios
    (The Scientific World Journal, 2012) Matallanas Peñas, Beatriz; Callejas Hervás, Carmen; Ochando González, María Dolores
    Spanish freshwater ecosystems are suffering great modification and some macroinvertebrates like Austropotamobius italicus, the white-clawed crayfish, are threatened. This species was once widely distributed in Spain, but its populations have shown a very strong decline over the last thirty years, due to different factors. Three Spanish populations of this crayfish—from different scenarios—were analysed with nuclear (microsatellites) and mitochondrial markers (COI and 16S rDNA). Data analyses reveal the existence of four haplotypes at mitochondrial level and polymorphism for four microsatellite loci. Despite this genetic variability, bottlenecks were detected in the two natural Spanish populations tested. In addition, the distribution of the mitochondrial haplotypes and SSR alleles show a similar geographic pattern and the genetic differentiation between these samples is mainly due to genetic drift. Given the current risk status of the species across its range, this diversity offers some hope for the species from a management point of view.

    The white-clawed crayfish in Spain—reply to Clavero and Centeno-Cuadros
    (Organisms, diversity and evolution, 2016) Matallanas Peñas, Beatriz; Ochando González, María Dolores; Alonso, F.; Callejas Hervás, Carmen
    This short communication is only intended to point out briefly and objectively some of the comments, appreciations, and sometimes misinterpretations made by Clavero and CentenoCuadros in their criticism to our article on the phylogeography of the white-clawed crayfish in Spain, recently published in this journal. For those skilled in the discipline of phylogeography, it is well known to be a multidisciplinary science. Therefore, we disagree with the argument of monodisciplinary approach given by these authors. The work of Matallanas et al. 2016, as all our previous ones, has no intention, no bias, or directionality. It clearly aims what the title synthesizes, an update of genetic information for the white-clawed crayfish in Spain. To achieve this, we have been the first to use two mitochondrial markers, the longest so far used, in a wide and representative sample of Iberian crayfish. A sample of crayfish fromNorthern Italy was just used as outgroup. The design is, therefore, very suitable and appropriate for the question posed.
