Habitat selection in Psammodromus algirus (Linnaeus, 1758) (Sauria: Lacertidae): age related differences
Abstract:
Habitat selection in adult and juvenile Psammodromus algirus was studied along a Mediterranean successional gradient in southwestern Iberia. Both age classes showed patterns of habitat selection which differed significantly from a random survey of the habitat. These patterns were different in the two age classes. Juveniles occupied loss wooded microhabitats with a denser low vegetation. Some morphological parameters thought to be related to habitat-use were measured; these did not differ between adults and juveniles. The biological meaning of the observed differences is discussed: intraspecific hostile interactions and predator avoidance are though to be involved, rather than thermal requirements.
