Abstract: Despite the strong microclimatic fluctuations, scarcity of nesting sites and unpredictable prey availability in open environments, ants are the dominant invertebrates in the tropical forest canopy. This study focused on the arboreal ants in Gorgona National Park, Colombia, a rainforest ecosystem (27¬ļC, 6 000mm average annual rainfall). In November 2007, 16 trees were sampled by fogging them with a biodegradable pyrethroid insecticide in four levels between 1 and 15 m above the understory vegetation. We found 53 species of Formicidae (24 genera and six subfamilies): two subfamilies had the most species: Formicinae (20 species) and Myrmicinae (17). The most abundant were arboreal species of¬†Azteca,¬†Dolichoderus (D. bispinosus¬†and¬†D. lutosus),¬†Camponotus¬†(C. atriceps,¬†C. claviscapus,¬†C.¬†championi,¬†C. excisus) and¬†Crematogaster¬†(C. brasiliensis,¬†C. carinata,¬†C. curvispinosa). Some species that are common at ground level (Wasmannia auropunctata¬†and¬†Camponotus sericeiventris)¬†were collected up to a height of 15 m. We remark the capture of¬†Nesomyrmex pittieri,¬†Crematogaster stolli,¬†Cephalotes basalis,¬†Anochetus bispinosus¬†and¬†Stigmatomma mystriops, species rarely found using conventional methods. Rev. Biol. Trop. 62 (Suppl. 1): 277-287. Epub 2014 February 01.
Translated abstract: Este trabajo se enfoc√≥ en el conocimiento de la mirmecofauna arb√≥rea de Gorgona, ecosistema insular de la zona de vida de bosque lluvioso tropical (27¬ļC, 6 000mm de precipitaci√≥n promedio anual). En noviembre de 2007 se muestrearon 16 √°rboles mediante la t√©cnica de nebulizaci√≥n usando un insecticida piretroide biodegradable, aplicado en direcci√≥n al dosel, desde cuatro alturas diferentes, entre 1 y 15m por encima de la vegetaci√≥n del sotobosque. Se encontraron 53 especies de Formicidae pertenecientes a 24 g√©neros y seis subfamilias, sobresaliendo por su riqueza las Formicinae (20 especies) y Myrmicinae (17). Por su abundancia, se destacaron especies arb√≥reas de los g√©neros¬†Azteca,¬†Dolichoderus¬†(D. bispinosus¬†y¬†D. lutosus),¬†Camponotus¬†(C. atriceps,¬†C. claviscapus,¬†C.¬†championi,¬†C. excisus) y¬†Crematogaster¬†(C. brasiliensis,¬†C. carinata,¬†C. curvispinosa). Algunas especies que son muy comunes a nivel del suelo (Wasmannia auropunctata¬†y¬†Camponotus sericeiventris), fueron colectadas a m√°s de 15m de altura. Se resalta la captura de¬†Nesomyrmex pittieri,¬†Crematogaster stolli,¬†Cephalotes basalis,¬†Anochetus bispinosusy¬†Stigmatomma mystriops¬†que usualmente no se detectan en muestreos comunes.¬†
