Symbiodinium diversity associated with zoanthids (Cnidaria: Hexacorallia) in No...
Rabelo, Emanuelle Fontenele; Rocha, Lidianne Leal; Colares, Geórgia Barguil; Bomfim, Tatiana Araújo; Nogueira, Vanessa Lúcia RodriguesSome marine animals have a dynamic mutualistic association involving heterotrophic coral animals (hosts) and autotrophic dinoflagellate endosymbionts in the genus Symbiodinium, known as zooxanthellae, which are directly involved in their physiology. Currently, there is limited knowledge of the Symbiodinium diversity associated with zoanthids from the Brazilian coast. Hence, this study assessed the diversity of ...

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 ...
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...
Primeiro registro de branqueamento no litoral do Ceará (NE-Brasil): Indicador d...
Soares, Marcelo de Oliveira; Rabelo, Emanuelle FonteneleCoral Bleaching is an environmental phenomena that has been used worldwide to demonstrate environmental changes in tropical marine ecosystems. This study reports the first occurrence of coral bleaching for the Ceará coast (NE Brazil). Although the monitoring covers the period from 2005 to 2010 taken on an artificial reef within a port area, and a sandstone intertidal reef, the bleaching event in corals (Sideras...
Oil spill in South Atlantic (Brazil): Environmental and governmental disaster
Soares, Marcelo de Oliveira; Teixeira, Carlos Eduardo Peres; Bezerra, Luís Ernesto Arruda; Paiva, Sandra Vieira; Tavares, Tallita Cruz LopesIn early September 2019, dense crude oil began to wash the beaches of Brazil's tropical coast. Four months after the first report, the oil has already been found along >3000 km of the Brazilian coastline on >980 beaches and was recently observed along the Amazon coast, making this oil spill the most extensive and severe environmental disaster ever recorded in Brazilian history, in the South Atlantic basin, and ...
Intertidal Anthozoans from the coast of Ceará (Brazil)
Soares, Marcelo de Oliveira; Rabelo, Emanuelle Fontenele; Cascon, Helena Mathews(Intertidal Anthozoans from the coast of Ceará, Brazil). The diversity and distribution of anthozoans were studied from intertidal regions along the state of Ceará, in northeastern Brazil.The material was collected between 2002 and 2004 from sandstone reefs (beach rocks) on 17 beaches that are part of this tropical coastline. Eight species were surveyed in ecological zones with high faunistic similarities. Envi...
Competitive interactions among zoanthids (cnidaria: zoanthidae) in an intertida...
Rabelo, Emanuelle Fontenele; Soares, Marcelo de Oliveira; Matthews-Cascon, HelenaSessile organisms that live in consolidated substrates frequently compete for space. Coral species have many strategies to face this competition, including harming their opponents or hindering their growth. In the present study, the competitive interactions between three species of zoanthids were investigated in the intertidal zone of a sandstone reef environment in northeastern Brazil. The competitive abilitie...
