A comparison of the leaf-litter ant fauna in a secondary atlantic forest with an adjacent pine plantation in southeastern Brazil

Abstract: RESUMO -A infl uência do refl orestamento com Pinus na estrutura da fauna de formigas de serapilheira foi investigada, estudando uma fl oresta Atlântica secundária inalterada há 30 anos e uma área refl orestada com Pinus elliottii no Sudeste do Brasil. Em 50 amostras de 1 m 2 tomadas em cada área, foram coletados 12.826 indivíduos, distribuídos em 95 espécies e 32 gêneros de formigas. Foram identifi cadas 60 espécies na área refl orestada com Pinus e 82 espécies na área de fl oresta secundária; aproximadamente… Show more

“…Such conditions may contribute to reduced numbers of ant species in these environments (Vallejo et al, 1987) and reduce the occurrence of specialist species (Pacheco et al, 2009). The ant species that colonise the area after impact were more aggressive types, and could banish or eliminate the resident species.…”

“…Espécies com morfologia e biologia especializadas ), com diversidade reduzida em ambientes antropizados (Pacheco et al 2009), também foram registradas, porém não em todas as áreas. Na área de mata de Biritiba Mirim encontra-se o maior número de espécies especialistas, com mandíbulas modificadas para predar dipluros campodeídeos (Prionopelta antillana), Myriapoda (Stigmatomma armigera e Stigmatomma elongatum) e ovos de artrópodes (Discothyrea sexarticulata) , Brown Junior 2000.…”

“…Thus, our experimental duration of 2 mo might be considered somewhat short, but should have been long enough to capture ant colonies relocated to capture resources within plots. Third, some queens are inßexible in adjusting brood rearing as food availability changes (Pacheco et al 2009). Regardless, many litter ant nests are ephemeral (Shik and Kaspari 2010); thus, much movement is because of nest relocation rather than colony founding (McGlynn 2006).…”

“…Food availability, even if not limiting, affects colony growth and colony abundance, and higher arthropod biomass in the forest and low-shade coffee may have contributed to greater colony growth rates therein. If food was signiÞcantly limiting in the highshade coffee, some ants may have cannibalized workers and brood to maintain colonies (Pacheco et al 2009) resulting in apparent low colony growth rates. Increases in the number and diversity of litter twigs positively affect leaf litter ants (Armbrecht et al 2004).…”
