摘要

The genus Leiocephalus (family: Tropiduridae) is present in Florida, Cuba, the Cayman Islands, the Bahamas, and Hispaniola (Etheridge 1966; Meshaka et al. 2005), and Leiocephalus macropus is one of six species found on Cuba, where it is endemic (Garrido 1973; Schwartz and Thomas 1975). Although this genus has a broad distribution and several studies on diet, sexual dimorphism, growth, reproduction, thermal ecology, anti-predator behavior and social signals of some species have been made, the knowledge on ecology and biology of Leiocephalus species still poor (Marcellini and Jenssen 1989, 1991; Cooper 2001; Nelson et al. 2001; Smith and Nickel 2002; Meshaka et al. 2006; Gifford and Powell 2007; Gifford et al. 2008). In genus Leiocephalus, all species are sexually dimorphic in body size, with males larger than females. Several studies investigate the possible causes of the sexual dimorphism observed in this genus throughout its distribution range (Schoener et al. 1982; Smith 1992; Nelson et al. 2001; Smith and Nickel 2002; Gifford and Powell 2007). However, no definitive explanation has been found yet. The study of the trophic niche and morphology of organisms permits the exploration of different ecological and evolutionary phenomena in animals (Metzger and Herrel 2005; Pincheira-Donoso 2008). Thus, the objective of this work was to provide data on the diet of the Curly-tailed lizard Leiocephalus macropus macropus (Cope, 1862) and on the sexual dimorphism of the sub-species in Guantanamo Province, Cuba.
