Descripción
The introduction of exotic tree species may cause conservation problems to natural  habitats, also true for original grasslands in coastal sand dunes. Natural plant cover is used by several species in coast line dunes of Buenos Aires, Argentina, among them the lizard Liolaemus  wiegmannii. Here we study the habitat use and abundance of this lizard inhabiting psammophytic  grassland in the coastal sand dunes of Buenos Aires, Argentina, where recently Acacia longifolia  was introduced. Surveys and lizard sampling were conducted in 40 transects distributed in four independent zones of 75 ha, each one with a different degree of invasion impact. We measured  structural and thermal features in relation to A. longifolia and native plants. The lizard L.  wiegmannii was three times more abundant in zones with equal or lower than 25 % percent of  coverage of A. longifolia. The Jacobs selectivity index showed that all age classes selected native  shrubs and avoided A. longifolia trees. These results were similar in green house experiments.  However, we found no significant differences in the use of any of these plants (introduced or  native) leaf litter. Structural and thermal characteristics of the habitat under the shrubs seemed to be more favorable for the physiological and behavioral performances of L. wiegmannii, whereas  the lower temperatures under A. longifolia may explain the lower presence of lizards in areas where this tree was introduced.
