Abstract
The effects of fluvial dynamics (e.g. flood pulse) on the ecosystems from Marchantaria Island (Manaus, AM, Brazil) are well known for its plant and animal communities and the scientific community who intent to investigate it. In the case of non-aquatic invertebrates like the ants, the usual response against the effects of flooding is through physiological or behavioural strategies, (e.g. migration). The principal aim of this work was to evaluate the effects of the flood pulse on ant communities in different environments from Marchantaria Island (White water floodplain Forest or Várzea Forests, grass belts, monocultures and disturbed areas) with pre-collected data from 1981-1982; 1985-1986; 1987-1988 and 1992, through
different soil and arboreal sampling methods. The dynamics of ant community occupation in this Island was studied, with reports on its general ecology.
