Importance of the genus Anolis (Lacertilia: Dactyloidae), as indicators ofhabitat status, in tropical rain forest of Chocó. rev. colombiana cienc. anim. Recia [online]. 2019, vol.11, n.1, pp.67-79.

In the present study, the value of Anolis species was quantified as ecological indicators of the conservation status of the habitats used by these species in an area of tropical forest in the department of Chocó. The Visual Encounter Survey (VES) method was used to establish species with greater relative abundance in a given site with different levels of vegetation coverage in the municipalities (Pan American Union, Certegüi, Lloro, Atrato and Quibdó), pattern "A" are indicator species of high levels of intervention where Anolis chloris stood out with 88.2% of relative abundance, pattern "B" refers to the indicator species of average levels of intervention, where A. latifrons with 75% of Individuals were registered at this tolerance level and the "C" pattern refers to species found in forested areas with a high level of conservation of their natural state, where A. anchicayae (92.8%) and A. Notopholis (exclusive) were the most important. Using a method that combines the specificity (exclusivity of habitat) and fidelity (frequency of occurrence in that same habitat), regarding the index of Indigenous Indicator Value "IndVal", four indicator species were reported, with a statistically significant difference between species; A. anchicayae (IndVal: 92.9%), for forest areas with many years ofnatural regeneration, A. chloris (IndVal: 88.2%), A. maculiventris (IndVal: 65.2%) and A. granuliceps (IndVal: 50.8%). In addition, an analysis of similarity and complementarity was carried out between the different coverages, indicating the exchange and exclusivity of species among them and later plotted abundance-range curves. Te results suggest the Anolis as an indicator group of the state of conservation of the tropical forests of Chocó.
