REGISTER OF NESTS OF THREE FORMICID SPECIES (HYMENOPTERA) IN RÍO CLARILLO NATIONAL RESERVE, METROPOLITAN REGION, CHILE

Abstract

The distribution of formicids Brachymyrmex giardii (Emery), Camponotus chilensis (Spinola), and Nothidris bicolor (Snelling) was registered with the minimum area method in two sectors of Río Clarillo National Reserve (33º 41-51’ S and 70º 24-29’ W), Pirque Commune, Metropolitan Region, Chile. One sector corresponded to an area with human presence, while the other corresponded to an area with less human intervention. The nests presented a group distribution, and the presence of people affected their density, frequency, and abundance.
