PIEDRA C, Lilliana  y  MAFFEI, Leonardo. Efecto de las actividades humanas sobre la diversidad de mamíferos terrestres en un gradiente altitudinal. Rev. biol. trop [online]. 2000, vol.48, n.1, pp.263-264. ISSN 0034-7744.

The effect of human activity on terrestrial mammals was studied with footprint counts in Guanacaste, Costa Rica (10°30'N, 85°40'W) in February 1998 (in fifty 2 m² quadrats). The most common species were Canis latrans, Didelphis marsupialis, Odoicoleus virginianus, Dasyprocta punctata and Tapirus bairdii. No stastically significant association was found between humna activity and mammal frequency in the footprint counts.
