RESUMOA Mata Atlântica vem, há séculos, sofrendo intervenções em decorrência do plantio de cana-de-açúcar. O presente trabalho objetivou verificar a influência da cana-de-açúcar pós-colheita sobre as populações de formigas epigeicas em contraste com áreas remanescentes de Mata Atlântica. As formigas foram capturadas com armadilhas pitfall e mediante coleta de serapilheira. Foram coletados 17.643 indivíduos, distribuídos em 111 espécies, sendo 81 espécies na Mata Atlântica e 47 espécies em cana-de-açúcar. Devido a Mata nativa ter apresentado maior diversidade de espécies do que a cultura de cana-de-açúcar, conclui-se que a monocultura e as práticas culturais interferiram negativamente na composição, diversidade, abundância e no número de indivíduos por espécie, na comunidade de formigas epigeicas.Palavras-chave: Agroecologia, biodiversidade, Formicidae, formigas de solo Diversity of soil ant (Hymenoptera: Formicidae) in dense Atlantic Forest and sugarcane plantations in the County of Igarassu-PE ABSTRACTThe rainforest, for centuries has been suffering interventions due to sugarcane plantation. The present work aimed to evaluate the influence of sugarcane after harvest over soil ant populations in contrast with areas of remaining rainforest. Ants were collected with pitfall traps and direct from the litter. A total of 17.643 individuals were collected, distributed in 111 species, being 81 species of the rainforest and 47 species in the sugarcane. Native forest showed greater diversity of species compared to sugarcane crop, which permit to conclude that the monoculture and the cultural practice alter the composition, diversity, richness and number of individuals per species in the community of soil ants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
