Abstract

The mangrove is an important system for studies on ecological processes related to primary production and nutrient cycling. This project has the aim of evaluate the predation and behavioral processes influences on the dynamics of mangroves. Therefore, the ecological patterns of Uca sp., Ucides cordatus e Goniopsis cruentata (feeding pattern, burrowing pattern and density), their wide geographic distribution and use as models in behavioral and ecological studies in mangroves, justify their use as experimental models to test 3 important questions: a) the Uca sp. activity on the sediment bioturbation; b) the impact of the density of detritivorous crabs on nutrient cycling; c) the impact of a predator (G. cruentata) in the top-down processes and trophic cascade. Two hypotheses will be tested: I: the Uca sp. activity in mangroves is responsible for the sediment bioturbation; II: the abundance of mobile consumers is responsible for the top-down processes structuring mangroves communities. As mangroves have a stable primary production (without huge changes), its consumers (detritivorous or predators) can reduce significantly the abundance and biomass of their feeding resource (through indirect behavioral interactions and also dense-dependent), the results will allow to infer on the importance of such consumers regulating direct or indirectly the feeding resource availability for others species, the nutrients cycle and the trophic cascade effect (top-down processes) influencing the primary productivity in this ecosystem.
