Abstract

Seasonal, monthly and hourly activity patterns of nine bat species were studied based on their capture rates at the Reserva Particular do Patrimônio Natural Feliciano Miguel Abdala (RPPN-FMA), Caratinga, Minas Gerais state, southeastern Brazil. The frugivorous and nectarivorous bat species have their activity closely related to the availability of food. Divergence in monthly and hourly activity is discussed for pairs of similar species and the hypothesis of reduction in competition for nectarivorous and frugivorous species are rejected. Further studies on frugivores-plants interactions should be conducted to assess the long term consequences for the whole system at the RPPN-MFA.A atividade mensal e horária de nove espécies de morcegos foi estudada a partir das taxas de captura na Reserva Particular do Patrimônio Natural Feliciano Miguel Abdala (RPPN-FMA), Caratinga, Minas Gerais, Brasil. As espécies frugívoras e nectarívoras parecem ter a atividade relacionada à disponibilidade de alimento. Divergências nas atividades mensal e horária são discutidas para pares de espécies similares e a hipótese da redução na competição para as espécies nectarívoras e frugívoras é rejeitada. Estudos adicionais sobre as interações de espécies de frugívoros entre si e com suas plantas de alimentação deveriam ser conduzidos de modo a prever as conseqüências de longo prazo destas interações para a manutenção desta comunidade no fragmento da RPPN-MFA.
