The most extensive oil spill registered in tropical oceans (Brazil): the balanc...
Soares, Marcelo Oliveira; Teixeira, Carlos Eduardo Peres; Bezerra, Luis Ernesto Arruda; Rabelo, Emanuelle Fontenele; Castro, Italo BragaThis article presents a synthesis of information about the massive oil spill in Brazil (2019/2020). The event afected 11 states; however, the majority of the oil residue was collected (~ 5380 tons) near nine states (99.8%) in northeastern Brazil. This spill was not the largest in volume (between 5000 m3 and 12,000 m3 ) recorded in tropical oceans, but it was the most extensive (2890 km). This spill develops an ...
Not just sand: The folly of dismantling the environmental protection of dunes i...
Soares, Marcelo Oliveira; Barros, Eduardo Lacerda; Guerra, Renan Gonçalves PinheiroThe Brazilian federal government has followed an open agenda and land use policy against existing legislation in the past three years using the false argument that it hinders national development. A recent loss has been the repeal of national resolution CONAMA 303/2002. With the action of the Brazilian government to revoke this resolution, the mobile and eolian dunes are currently without legal national protect...
The flourishing and vulnerabilities of zoantharians on Southwestern Atlantic reefs
Soares, Marcelo Oliveira; Kitahara, Marcelo Visentini; Santos, Maria Eduarda Alves; Bejarano, Sonia; Rabelo, Emanuelle FonteneleIn the Southwestern Atlantic reefs (SWA), some species of massive scleractinians and zoantharians are adapted to turbid waters, periodic desiccation, and sediment resuspension events. Moreover, phase shifts in this region have mostly been characterized by the emergence of algae and, less typically, zoantharians. However, nutrient excess and organic pollution are key drivers of the hard coral habitat degradation...
Disentangling beach litter pollution patterns to provide better guidelines for ...
Brabo, Lucio; Andrades, Ryan; Franceschini, Simone; Soares, Marcelo Oliveira; Russo, Tommaso; Giarrizzo, TommasoBeach litter represents a worldwide problem impacting both terrestrial and aquatic environments. In the present study, we assessed beach litter pollution in a prominent touristic site in Brazil, the Jericoacoara National Park. In particular, we applied a delta-generalized additive modeling (GAM) approach in order to investigate pollution hotspots and to provide better guidelines for coastal environmental manage...
Oil and plastic spill: 2021 as another challenging year for marine conservation...
Magalhães, Karine Matos; Rosa Filho, José Souto; Teixeira, Carlos Eduardo Peres; Coelho-Jr, Clemente; Lima, Maria Cecilia SantanaAfter two years of the most extensive (2890 km of coastline affected) oil spill on the Brazilian coast (2019), a new event of unknown origin brought about 1.3 tons of plastics and oil to the Fernando de Noronha Archipelago; formed by 21 oceanic islands with high endemism, productivity and unique ecosystems such as rich seagrass and rhodolith beds and the only insular mangrove ecosystem in the South Atlantic. Th...
Trophic ecology of Caribbean octocorals: autotrophic and heterotrophic seasonal...
Rossi, Sergio; Schubert, Nadine; Brow, Darren; Gonzalez-Posada, Alba; Soares, Marcelo OliveiraStudies over the past decades indicate that octocorals are becoming the dominant group in some areas of the Caribbean. Yet, basic knowledge about the trophic ecology of these organisms and their seasonal and speciesspecific variability is still scarce, though this might play a key role in determining their importance in benthic–pelagic coupling processes and, consequently, their role in carbon cycles. In the pr...
Marginal reef paradox: A possible refuge from environmental changes?
Soares, Marcelo OliveiraThe occurrence of coral reef communities under extreme and different-from-optimum conditions makes it possible to test hypotheses about resilience in the face of increasing local and global impacts. Recently, coastal marginal reefs have been hypothesized to provide refugia from natural and anthropogenic impacts. Herein, I present empirical evidence contradicting this assumption and explain a new idea, called th...
Estuaries and Gelatinous zooplankton: New records of Ctenophora from the Tropic...
Campelo, R.P.S; Diaz, Xiomara.F.G; Santana, Jana R; Costa, Alejandro E.S.F; Nogueira Junior, Miodeli; Soares, Marcelo Oliveira; Neumann -Leitao, SigridThe fauna of ctenophores in the coastal zone of tropical Southwestern Atlantic is virtually unknown. Mnemiopsis leidyi and Beroe ovata are important components of pelagic communities as top predators, which are occasionally abundant and widely distributed on coastal regions of the western Atlantic. However, in this region most of the records are in subtropical areas of SW Atlantic, North Atlantic or in the Cari...
Composition and cross-shelf distribution of ichthyoplankton in the Tropical Sou...
Mota, E.M.T.; Garcia, T.M.; Freitas, J.E.P.; Soares, Marcelo OliveiraThe spatial distribution, abundance, and composition of ichthyoplankton are key ecological features for the conservation of biodiversity and sustainability of fisheries. Despite their importance, knowledge about these features in the equatorial waters of the planet is still scarce. The aim of this study was to assess these features in the Tropical Southwestern Atlantic (northeastern Brazil). Two oceanographic c...
Marine debris from the past - contamination of the Brazilian shore by a WWII wreck
Teixeira, Carlos Eduardo Peres; Cavalcante, Rivelino Martins; Soares, Marcelo Oliveira; Ribeiro, Felipe Bezerra; Bezerra, Luis Ernesto ArrudaIn 2018, unidentified packages appeared along approximately 1600 Km of the Brazilian coastline causing widespread pollution to beaches and danger to society. The packages were found to be bales of raw rubber ranging in size from 0.06 m3 to 3.4 m3 and weighing up to 200 kg. A few bales were marked with the stamp “Product of French Indochina” and colonized by the barnacle Lepas anatifera, an oceanic species. We f...
