RENGIFO M., Jhon Tailor; CASTRO HERRERA, Fernando  e  PURROY IRAIZOS, Francisco José. Habitat use and ecomorphology relation of an assemblage of Anolis (Lacertilia: Dactyloidae) in the Chocoan natural region from Colombia. Acta Zool. Mex [online]. 2015, vol.31, n.2, pp.159-172. ISSN 2448-8445.

The habitat used by Anolis in tropical rainforest was evaluated using the Visual Encounters Survey method (VES) in three vegetation cover, there was a statistical difference in vertical position (X2 = 58.7, df = 3, P< 0.0001), substrates (X2 = 272.1, df = 4, P < 0.0001) and perch diameter (X2 = 147.5, df = 6, P < 0.0001). It was found that A. maculiventris and A. anchicayae are the species with largest IVI with 0.69 and 0.51 (33 and 25%) respectively, measuring the importance value of species in different vegetation cover. This study highlights ecomorph species trunk-branch (A. malkini, A. chloris, A. latifrons, A. lyra and A. notopholis), all species occur on the trunks of trees and shrubs, and species such as A. maculiventris and A. granuliceps microhabitat can be found on the ground usually occupying fallen logs and litter; climatic variables measured did not show a strong correlation with recorded abundances.
