Experimental introduction of Liolaemus lutzae (Squamata: Iguanidae) in Praia das Neves, state of Espírito Santo, Brazil: a descriptive study 18 years later.

Abstract

This article examines the results of the introduction into Praia das Neves, state of Espírito Santo, Brazil, of Liolaemus lutzae, a lizard species threatened with extinction. Since there are few studies that evaluate how species establish and adapt to new environments, it is useful to assess to what extent the introduction of a critically endangered species into an area similar to where it originally occurred can help reduce its decline in number of individuals and avoid its possible extinction. This study presents the first results of an ongoing monitoring survey set up after the experimental introduction. It was analysed how the introduced population uses space and food, and compared these characteristics to that of the original population at Barra de Maricá, Rio de Janeiro state. The morphological measurements of specimens from both populations were also compared. Both make similar use of the microhabitat, but there are differences in their diets. It is recommend that the introduced population, potential competitors, predators, parasites, and the habitat characteristics continue to be monitored, so as to insure that this species will not become a threat to Praia das Neves beach community.
