Inventário rápido da mirmecofauna dos parques nacionais da Chapada dos Guimarães - MT e do Iguaçú - PR

Abstract

In the present study we carried out a rapid inventory of the diversity ants of two Brazilian National Parks, in order to compare the faunistic similarity between these natural areas of the Cerrado and Atlantic Forest Biomes; whereas little is known about the diversity of ants of these environments. The collections were carried out from 2015 November 7 to 13 in the Iguaçú National Park and from 2016 March 24 to April 2 in Chapada dos Guimarães National Park; using the following sampling methods: manually with entomological forceps and glass bottles containing 96% alcohol; and using Malaise traps; sardine baits; yellow pans; and mini-Winkler extractor. The specimens were identified at species level and morphoespecies and deposited in MuBio-UFGD entomological colletions. In total, 171 species / morphospecies were registered in 54 genera. The fauna similarity between the Parks was 40.2% by the Sörensen index and the most diverse genera in the number of species were Pheidole and Camponotus. The greatest species richness was found in Foz do Iguaçú National Park (119). The rapid inventory showed to be able to estimate the number of species of the localities and they have a great application in the monitoring programs and ant conservation status.
