TITLE:

SUMMARY:

It is clear that environmental changes have occurred all over the planet, either by natural or anthropological causes, increasing the damage to the environmental quality that lead to a reduction of habitat for many species and an increase in mortality rates. The fact is that even changes not so significant in the short term can cause stress and changes in the behavioral ecology of animals that play the role of bioindicators of local environmental quality. Such behavioral changes directly influence the ability of species to survive and reproduce, resulting in long-term biochemical and physiological changes through natural selection. In areas of mangroves, for example, which are among the most compromised ecosystems in America because of the advancement of urbanization on the coasts, the fiddler crabs are evidenced as bioindicators because of the high sensitivity of these animals to environmental stresses. As such, the present study aims to investigate changes in the behavioral ecology of the fiddler crabs Uca maracoani, regarding the standardization of waving display in mangrove areas of Mucuri - BA, in face of changes in local abiotic factors. For this purpose, a previously selected area in the Mucuri River estuary was monitored, using two types of sampling through filming: instantaneous sampling and focal animal sampling, to verify the abundance of individuals outside the burrow and possible variations in the waving display standard performed by males, considering the tidal and light-dark cycles. Statistical analyses were realized to verify the influence of lunar phase, salinity, temperature, humidity, tidal regime and light, in order to verify possible variations that may interfere with their behavior. At the end of this project it is expected to verify the existing changes in the pattern of waving display among male individuals and interference in the population abundance outside the burrows in the area to be studied, as well as the potential influences that caused it.
