Abstract
Introduction. Bats (Order: Chiroptera) due to diversity and feeding habits, are important
to assess changes in diversity and composition of species in environments that have
suffered human disturbances, such as livestock landscapes. Bats to a large extent, their
foraging activity depends on the presence of arboreal elements, such as patches of
vegetation, forest edges, and isolated trees (Medellín et al., 2000; Galindo-González and
Sosa, 2003; Manning et al., 2006). Objective. Determine the importance of bats and
scattered trees in the conservation of biological diversity in two livestock landscapes, in
Jalisco and Oaxaca, Mexico. Methods. Through systematic sampling, bats were captured
monthly with mist nets, in two cattle ranching landscapes. Results and discussion. In
Jalisco, a low density and diversity of dispersed trees was obtained, where 455 individuals
belonging to 18 species of bats were captured. Demodus rotundus, was the dominant
species. While, in Oaxaca, the grasslands presented high diversity and density of dispersed
trees, where 713 individuals of 13 species of bats were captured. Sturnira hondurensis
was the most abundant species. A low diversity of bats and a high abundance of the
common vampire (D. rotundus) have been reported in cattle pastures, which is an indicator
of the disturbance generated by extensive livestock (Galindo-González and Sosa, 2003;
García-Morales et al., 2013), as in the case of Jalisco, where extensive livestock farming is
decreasing biological diversity. In this way, it is proposed to maintain and even increase the
presence of tree elements within livestock landscapes, both as scattered trees, riparian
corridors and forest fragments around pastures. Conclusion. The importance of bats and
tree elements in livestock landscapes for the conservation of biological diversity and as a
strategy for population control of the common vampire was determined.
