          Abstract

          La dispersión endozoocórica implica la dispersión de semillas a través de las heces luego de su in­gestión por los animales. Este trabajo evalúa el rol de la liebre europea, Lepus europaeus, como dispersor legítimo de semillas, en un ambiente del ecotono Monte-Patagonia de la provincia de Mendoza. Los muestreos fueron realizados en los meses de marzo y abril de 2010. En 43 de las 200 heces analizadas se encontró un total de 129 semillas que correspondieron a 8 taxones de plantas diferentes. Casi el 60% correspondieron a la familia Poaceae, mientras que la única especie exótica hallada fue Polygonum aviculare. Sin embargo, no se puede descartar que este lepórido disperse alguna otra especie exótica ya que algunas semillas de monocotiledóneas no pudieron ser determinadas. Todas las semillas de P. aviculare y de especies de la familia Amaranthaceae se encontraron dañadas, mientras que las semillas de Prosopis sp. aparecieron sanas. Nuestros resultados indican que la liebre europea es un dispersor endozoocórico de semillas, principalmente de Poáceas, en el ecotono Monte-Patagonia.

          Endozoochorous dispersal involves the dispersal of seeds through feces after being ingested by animals. This work assesses the role of the European hare, Lepus europaeus, as a legitimate seed dispersal in an environment of the Monte-Patagonia ecotone in the province of Mendoza. Sampling was conducted between March and April 2010. In 43 of the 200 feces analyzed, a total of 129 seeds was found which corresponded to 8 different plant taxa. Nearly 60% of them belonged to the family Poaceae, whereas the only exotic plant species found was Polygonum aviculare. However, the possibility of this leporid dispersing some other exotic monocots cannot be ruled out because some of them could not be determined. All seeds of P. aviculare and of species of the family Amaranthaceae were damaged, whereas the seeds of Prosopis sp. were undamaged. Our results indicate that the European hare is an endozoochorous seed disperser, mostly of Poaceae, in the Monte-Patagonia ecotone.
