The natural landscape of southeastern Brazil has suffered since its colonization with an intense
human exploitation that resulted in the replacement of Atlantic Rainforest by crops and pastures.
In general, such practices have led to land degradation, preventing its rational use. Land
reclamation projects need to understand the state of ecosystems conservation and their
interactions with the landscape in order to ensure the success of interventions. Therefore, the
soil fauna communities can be used as a bioindicator of the land degradation/ reclamation
intensity. The study area is located at the municipality of Itaboraí, Rio de Janeiro state, Brazil.
The landscape is characterized by rock formations of the Proterozoic period with up to 100 m
high, hills from the Tertiary period with 40 m of maximmum high and plains formed in the Quaternary
period (FONSECA, 1988). The vegetation consists of degraded pastures with the predominance
of Brachiaria grass and small fragments of Atlantic secondary forest located only in Proterozoic
hills. The aim of this work was to verify how geomorphplogical and vegetational factors can
interact and change the communities of soil fauna.
The epigeic soil fauna was sampled in March 2007, with the aid of pitfall traps (MOLDENKE,
1994). Transects were established in three longitudinal portions of the slopes of the Proterozoic
and Tertiary hills. In the plains were evaluated the floodplain and the terrace deposition of the
Quaternary. In each transect were installed nine traps spaced 5 m. Combinations of
geomorphological and vegetational factors resulted in 11 transects.
The principal component analysis grouped the 11 transects in 3 clusters, which correspond to
different levels of soil fauna diversity. In the first cluster were joined the transects established in
the Proterozoic hills covered by secondary Atlantic Rainforest, with the highest values of Shannon
index, groups richness and eveness. In the second cluster with intermediate levels for the diversity
indices are the transects of the Tertiary and Quaternary located at the base and top of the
slopes. The last cluster grouped the the Proterozoic areas covered by pastures and the slope
median portion of Tertiary hills, with the diversity lowest levels. MenosThe natural landscape of southeastern Brazil has suffered since its colonization with an intense
