    Heritability of Batrachochytrium dendrobatidis burden and its genetic correlation with development time in a population of Common toad (Bufo spinosus)
    (Evolution: International Journal of Organic Evolution, 2016) Palomar García, Gemma; Cano, Jose Manuel; Bosch López, Jaime Alfonso
    Despite the important threat that emerging pathogens pose for the conservation of biodiversity as well as human health, very little is known about the adaptive potential of host species to withstand infections. We studied the quantitative genetic architecture responsible for the burden of the fungal pathogen Batrachochytrium dendrobatidis in a population of common toads in conjunction with other life-history traits (i.e., body size and development rate) that may be affected by common selective pressures. We found a significant heritable component that is associated with fungal burden, which may allow for local adaptation to this pathogen to proceed. In addition, the high genetic correlation found between fungal burden and development time suggests that both traits have to be taken into account in order to assess the adaptive response of host populations to this emerging pathogen.

    Tracking the introduction history of Ichthyosaura alpestris in a protected area of Central Spain
    (Conservation Genetics, 2017) Palomar García, Gemma; Voros, Judit; Bosch López, Jaime Alfonso
    One of the main goals of protected areas, especially National Parks, is biodiversity conservation. Taking into account the multiple negative impacts that allochthonous animals can cause in an ecosystem, it is important to know and track the introductions in order to take efficient management measures to enhance biodiversity conservation. We study the origin of an Ichthyosaura alpestris population in Peñalara Massif within the Guadarrama National Park, Central Spain. To accomplish this goal, we used nine microsatellite markers and sequences from 16S and ND4 genes. Both mitochondrial DNA and microsatellite analyses showed the close relationship between Peñalara and Asturian populations, despite their geographical distance, confirming the allochthonous origin of this population. Interestingly, more than one introduction event seems to have occurred with individuals from Lago Ercina and Pozos de Lloroza populations participating in the founding of the Peñalara population. Due to predation, competition and transmission of diseases enhanced by its ongoing expansion, I. alpestris population might be considered a threat to Peñalara biodiversity. We advise an efficient population control to conserve the biodiversity within the Guadarrama National Park and an update of the position of this population in the Spanish indexes and list of species.
