Resumen
The ant assemblages of a fragment of secondary tropi-cal dry forest located in the Botanical Garden of Cali are presented. Two habitats were chosen: a fragment of forest and a pasture matrix. Samples were taken monthly for six months, using a linear transect of 100 m, with 10 stations spaced 10 m. At each station pitfa-ll traps, epigeal bait and arboreal, sifting and removal of 1 m2 of litter and manual capture survey techniques were applied. Richness, abundance and diversity of ant habitats were determined. Correlation coefficients and regression between temperature, relative humidi-ty and richness of ants were calculated. A total of 13 170 ants representing 55 species, 35 genera and six subfamilies were collected. The forest had the highest species richness with 90.9%. This wealth of diversity indicates the conservation value of the Valle del Cau-ca myrmecofauna. Although the forest is in the pro-cess of regeneration, strongly disturbed by constant fire and human intervention, the ant species richness shows that it remains an invaluable source of biologi-cal resources for the conservation of species.Keys words: dry ecosystems, formicidae, fragmenta-tion, hymenoptera
