SUMMARY:

The fibropapillomatosis (FP) is debilitating disease for the sea turtles,
characterized by the presence of tumors and affects mainly green turtles, being
considered a pandemic for this species. The etiology of the disease is related to
the presence of a herpesvirus associated with environmental degradation and,
for this reason, it can be used as an indicator tool for environmental quality.
Despite this relationship, it is not defined how anthropic impacts affect the
manifestation of PF. To fill this gap, this study used information publicly
available by the various Beach Monitoring Projects (BMPs) existing in Brazil
under the responsibility of IBAMA. We analyzed ~ 15,000 green turtles stranded
in six coastal states in the country in the Northeast and Southeast regions to
observe the prevalence of each region and the variations in time and space. In
addition, night light (NL) information was used as a proxy for urbanization,
sanitation system and water surface temperature as environmental variables
that could be related to the manifestation of the disease. Our results show that
the prevalence in Brazil has increased since the first year evaluated in the
study. Furthermore, the Southeast region, the most urbanized, concentrates the
highest prevalence rates when compared to the Northeast, less urbanized.
However, the statistical models not differentiated between the PF and the
observed environmental variables, possibly due to the other variables that were
not considered or act more strongly on a smaller scale.
