ABSTRACT
Atta cephalotes (L.) presents a wide distribution in the Neotropical region. In Brazil, this species is disjunctly distributed in the Amazon region and in the states of Maranhão, Pernambuco and southern Bahia, all of which belong to Northeast Region. Here we report on a survey of Atta colonies in 42 remnants of the Atlantic rainforest in Alagoas and Pernambuco. Our results include new records of A. cephalotes in the state of Alagoas and thereby extend the known distribution area of its southern populations in Northeast Brazil. In addition, the species was strongly associated with well-conserved forest remnants, indicating that it is highly sensitive to disturbance. We suggest that, in the fragmented scenario of the northeastern Atlantic forest, A. cephalotes may be replaced by A. sexdens, which was present throughout all survey sites.
RESUMO
Atta cephalotes (L.) apresenta ampla distribuição na região Neotropical. No Brasil, foi registrada na região Amazônica e nos estados do Maranhão, Pernambuco e sul da Bahia, todos pertencentes à Região Nordeste. Neste trabalho é apresentado o registro de A. cephalotes em 42 remanescentes de Floresta Atlântica nordestina em Alagoas e Pernambuco. Os resultados incluem novos registros de A. cephalotes em Alagoas, ampliando a distribuição da espécie no Nordeste. Além disso, mostram que a espécie é fortemente associada a remanescentes de floresta bem conservados, indicando alta sensitividade a perturbações. É sugerido que, no cenário fragmentado da Floresta Atlântica nordestina, A. cephalotes pode estar sendo substituída por A. sexdens que esteve presente em todas as áreas amostradas.
