The extensive oil spill (> 2,900 km) that occurred in the southwestern Atlantic (2019/2020) increased the vulnerability of the Brazilian coast, affecting marine and coastal protected areas (MPAs). In addition to supporting conservation, MPAs are sustainably used by local populations to help maintain ocean-dependent livelihoods. In this sense, we ai...
Article
Despite a global phase out of some point sources, mercury (Hg) remains elevated in aquatic food webs, posing health risks for fish-eating consumers. Many tropical regions have fast growing organisms, potentially short food chains, and few industrial point sources, suggesting low Hg baselines and low rates of trophic magnification with limited risk...
Article
An extensive network of Protected Areas (PA) has been established across the Brazilian Amazon, but this PA system still suffers from a shortage of funding resources and environmental managers. New conservation strategies that successfully align social aspirations with biodiversity conservation are therefore imperative. Although approaches exist tha...

Article
River meander migration is a process that maintains biodiverse riparian ecosystems by producing highly sinuous rivers, and oxbow lakes. However, although the floodplains support communities with fish and other practices in the region, meandering rivers can directly affect the life of local communities. For example, erosion of river banks promotes t...
Article
The last two decades has seen a global trend in Marine Protected Area (MPA) management from top-down to more bottom-up approaches. Moreover, recent research suggests that evaluation of MPA performance should be participative, fully engaging multiple stakeholders, including local community representatives, in the assessment process. The effectivenes...
