Abstract

PINILLA-RENTERIA, Efren; RENGIFO-MOSQUERA, Jhon Tailor  and  SALAS LONDONO, Jovanny. Dimorphism, habitat use and diet for Anolis maculiventris (Lacertilia: Dactyloidae), in tropical rainforest in Chocó, Colombia. Acta biol.Colomb. [online]. 2015, vol.20, n.1, pp.89-100. ISSN 0120-548X.  http://dx.doi.org/10.15446/abc.v20n1.39109.

We studied some aspects of the population biology of A. maculiventris, in areas of tropical rainforest in the natural region of Choco. The males and females brown coloration with a small mole on the back of the head, the proportions and gender in the captured individuals showed significant statistical differences (X2: 4,81, gl: 1, p: 0,028). The degree of sexual dimorphism (GDS) and sexual dimorphism index was 1.08, mm and 8.5 mm respectively. Females differ significantly from males in all the parts of the body measures. 30 Individuals have spread, which was determined to their reproductive status and failed to register a size minimum of maturity (LHA) in females is 30.7 mm, with a maximum of 39.9 mm and an average of 36.5 mm. In the male the minimum maturity sexual 30.4 mm, and a maximum of 36.7 mm, with an average of 33.8 mm; which indicates that females were more large than males. Assessed habitat use, showing significant statistical differences between the used substrate (X2=16,89, gl: 3, p: 0,001); and for vertical positions, showed the same behavior (X2=3,77, gl: 3, p: 0,207). For analyzing dietary species spread 30 stomach, of which 15 belonged to males and 15 females, will register a total 46 gastrointestinal dams that compose its diet showing the orders Coleoptera and Hymenoptera (Formicidae) as the of greater relative importance in the diet.
