ESCARRAGA-SAAVEDRA, Alcibíades  and  CAMACHO-REYES, Jairo A.. Composition of anuro-fauna associated to the Bojaba river lower basin (Cubara-Boyaca, Saravena-Arauca). Orinoquia [online]. 2019, vol.23, n.2, pp.97-108. ISSN 0121-3709.  https://doi.org/10.22579/20112629.573.

An analysis of the composition and diversity of anura fauna associated with the lower Bojabá River basin, in the municipalities of Saravena-Arauca and Cubara-Boyaca, is carried out. Aspects of species numbers, true diversity indices and effective Hill numbers are reviewed. The sampling was carried out in September 2013 and March 2014 with two different climatic temporalities in gallery forest coverages, savanna and wetlands. 231 amphibian individuals are registered, distributed in five families, 10 genera and 18 species, the observed diversity of order q = 0, q = 1 and q = 2 explained that wetlands are the most diverse coverage, however, q = 0 indicates that gallery forests could accommodate more diversity. The species found come from eastern savannas with physiological adaptations to the intervened ecosystems and with generalist behavior.

Keywords : Diversity; Species; Effective Hill Numbers; Gallery Forests; Orinoquia.
