espanolLos sistemas dunares son los ecosistemas mas degradados de toda la costa europea y la actividad humana ha causado una profunda transformacion en la costa mediterranea de Espana. En Torredembarra (Tarragona, Espana) habita una poblacion de lagartija colirroja Acanthodactylus erythrurus en algunas de las dunas naturales y parches de vegetacion que aun existen, donde la fauna silvestre coexiste con unas intensas actividades turisticas. Nuestro objetivo fue conocer si las pasarelas instaladas sobre las dunas estaban afectando a la movilidad de la lagartija colirroja. Se comparo la movilidad de lagartijas marcadas entre dos zonas con habitat similar, pero una con pasarelas y otra sin. Se observo que las pasarelas acortaron las distancias entre reavistamientos consecutivos y que afectaban mas a los juveniles de lagartija colirroja que a los adultos. Llegamos a la conclusion de que la pasarela puede estar afectando a las interacciones sociales naturales de la especie. EnglishDune systems are the most degraded ecosystems of the entire European coast, and human activity on the Mediterranean coast of Spain has caused dramatic transformation. In Torredembarra (Tarragona, Spain), a population of spiny–footed lizards Acanthodactylus erythrurus inhabits the few remaining natural dunes and vegetation patches where wildlife coexists with intensive tourism activities. Our aim was to know whether walkways installed across the dunes were affecting the mobility of the spiny–footed lizard. We compared the mobility of marked lizards in two areas with a similar habitat, one with and one without a walkway. We found that the walkway reduced the distances between consecutive resightings, affecting juveniles more than adults. We conclude that the walkway may affect social interactions in the species.
