Considering an integrated malacology approach to ecosystem assessment: a socio-ecological system analysis of the terrestrial mollusks in an atlantic rainforest area, southeastern Brazil

Abstract

The invertebrate group is not considered in environmental studies. When they are remembered, the studies are vague, superficial and do not give the due importance that the group has in the ecosystem dynamics. This paper aimed at placing the terrestrial mollusks in the discussion agenda of complex socio-ecological systems and analyzed the interactions of these mollusks with the other components of the socio-ecological subsystems. The analysis was based on the theoretical-methodological framework proposed by Ostrom and discussed how terrestrial mollusks have the potential to support actions for decision-making in biodiversity conservation, public health and local economy. The framework presented four subsystems categorized as ecological, political, social and economic, with the Sooretama Biological Reserve in the Northern state of Espirito Santo as a geographical boundary. The results allow us to perceive that terrestrial mollusks have essential characteristics that reflect into ecosystem health, acting in an integrated way with the dynamics of environmental services and the equilibrium of habitats.
