Microhabitat selection by the Iberian rock lizard Lacerta monticola: Effects on density and spatial distribution of individuals Original Research Article

We describe microhabitat selection in the Iberian rock lizard Lacerta monticola, a species endemic to some high mountains of the Iberian peninsula. This species is potentially threatened, in particular, by changes in habitat conditions on the ski slopes and from associated buildings in resorts that proliferate precisely in areas it favours. We analyse the relationship between habitat physical structure and population densities, in order to establish a predictive habitat-population model. Lizards select large rock screes and Cytisus bushes, but scarcely use Juniperus bushes and grassy areas. Individuals have an aggregated spatial distribution. The application of this habitat model may allow predictions to be made about the response of L. monticola to artificial and natural habitat changes, and could help to manage suitable habitats for populations.
