Résumé
The effect of human development on six diurnal mammal species was studied using transects in the Punta Leona Private Wildlife Refuge, Puntarenas, Costa Rica during the dry season months of March and April 2006. Individuals/km was recorded for each species in more developed (MD) (near paved roads, buildings, construction, or deforested trees) and less developed areas (LD) (secondary forest). The white-faced apuchin monkey (Cebus capucinus) (n = 233), coatimundi (Nasua narica) (n = 46), and Central American spider monkey (Ateles geoffroyi) (n = 36) demonstrated a preference for less-developed habitats. The nine-banded armadillo (Dasypus novemcinctus) (n = 4), tamandua (Tamandua mexicana) (n = 2) and variegated squirrel (Sciurus variegatoides) (n = 5) were observed infrequently. White-faced monkeys avoided construction areas, but received artificial food daily in developed areas. Coatimundis also received artificial foods daily and showed aggression towards guests. Rev.

Se estudiaron seis especies de mamíferos mediante transectos durante la estación seca tardía (marzo y abril) de 1996 en el Refugio de Vida Silvestre de Punta Leona, Puntarenas, Costa Rica. Se registró la cantidad de animales por km en lugares con mucho efecto humano (cerca del caminos pavimentados, edificios, construcción, y deforestación) y lugares con menos efecto. El mono carablanca (Cebus capucinus) (n = 233), el pizote (Nasua narica) (n = 46), y el mono araña centroamericano (Ateles geoffroyi) (n = 36) prefirieron lugares con menos efecto. Se observó pocos armadillos (Dasypus novemcinctus) (n = 4), osos hormigueros (Tamandua mexicana) (n = 2), y ardillas (Sciurus variegatoides) (n = 5). Los monos carablancas y pizotes aceptan alimentos artificiales y los pizotes fueron agresivos con los turistas. Los carablancas evitan los lugares con construcciones y los caminos pavimentados.
