A catalogue of reptiles of Monfragüe National Park (Spain), with molecular characterization of populations of <em>Blanus</em> Wagler, 1830 in this protected area

Abstract

Monfragüe National Park (Cáceres, Extremadura, Spain) is a protected area in central-western Iberia,including some of the best preserved primary Mediterranean vegetation. Legal protection dates back to 1979 (first as a Natural Park and then as a National Park), but knowledge about its reptile communities is so far limited to sparse records. In this paper we present an updated species list based on 521 records covering 163 1x1 km UTM grids in the study area, compiled in the period 2000-2019. We detected 20 native species, representing 71.4% of the reptile fauna in Extremadura and 35% of the ibero-balearic reptile fauna. Additionally, based on molecular analyses populations of the amphisbaenid genus Blanus in the study area are assigned to the oriental Iberian taxon, B. cinereus. The new records extend the known distribution of the different reptile species in the study area in 56 10x10 km UTM grids. Species presenting more restricted distributions in Monfragüe are Lacerta schreiberi (one 1x1 grid), Emys orbicularis, and Acanthodactylus erythrurus (four 10x10 grids each).
