Mollusks from two estuarine areas in Ceará State, northeastern Brazil, with new...
Barroso, Cristiane Xerez; Rabay, Soraya Guimarães; Meirelles, Carlos Augusto Oliveira de; Matthews-Cascon, HelenaWe analyzed qualitatively the malacofauna found in the tidal zones of Banco dos Cajuais and Ilha Grande estuarine complex, both in Ceará State, northeastern Brazil. Qualitative data on the malacofauna from Banco dos Cajuais and the Ilha Grande estuarine complex were obtained by systematic sampling in 2008 and 2009 during field activities for the “Migratory Shorebirds Conservation and Shrimp Farming in Northeast...
Molluscs from the upper mesophotic zone in a scarcely known reef of the Western...
Barroso, Cristiane Xerez; Freitas, João Eduardo Pereira de; Spotorno, Paula; Tâmega, Frederico Tapajós de Souza; Franklin Júnior, WilsonDespite the increasing focus on biodiversity of mesophotic coral ecosystems (MCEs) on a global scale, some biological groups, such as molluscs, are still poorly investigated. The taxonomic diversity of the molluscan fauna of a scarcely known MCE of the Western Equatorial Atlantic, Northeastern Brazil, was surveyed. Samples were collected along the shallower strata of the upper mesophotic zone (between 33-36 m d...
Neritidae (Gastropoda, Neritimorpha) from the malacological collection prof. He...
Barroso, Cristiane Xerez; Rocha-Barreira, Cristina de Almeida; Matthews-Cascon, HelenaThe basic information obtained from scientific collections help us to understanding of Earth’s diverse biota and its biological processes. The Malacological Collection Prof. Henry Ramos Matthews (CMPHRM) of the Universidade Federal do Ceará (UFC), Brazil, is a reference about the biodiversity, mainly marine, of northeastern Brazil. In this collection, the gastropod molluscs of the family Neritidae were among th...
Marine hardbottom environments in the beaches of Ceará state, equatorial coast ...
Carneiro, Pedro Bastos de Macêdo; Ximenes Neto, Antônio Rodrigues; Feitosa, Antônio Rodrigues Caroline Vieira; Barroso, Cristiane XerezThis paper is a literature review on marine hardbottom environments (MHE) that emerge in coastal regions in the Brazilian state of Ceará. This stretch of the Brazilian coast houses several rock formations, which are widely distributed in the intertidal zone. These formations have various origins and composition, ranging from crystalline rocks to biogenic structures, but most are composed by sandstones. These su...
Molecular evidences confirm the taxonomic separation of two sympatric congeneri...
Barroso, Cristiane Xerez; Freitas, João Eduardo Pereira de; Cascon, Helena Matthews; Bezerra, Luis Ernesto Arruda; Lotufo, Tito Monteiro da CruzA reliable taxonomy, together with more accurate knowledge of the geographical distribution of species, is a fundamental element for the study of biodiversity. Multiple studies on the gastropod family Neritidae record three species of the genus Neritina in the Brazilian Province: Neritina zebra (Bruguière, 1792), Neritina virginea (Linnaeus, 1758), and Neritina meleagris Lamarck, 1822. While N. zebra has a well...
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 ...
Marine benthic communities affected by the Doce River (southwestern Atlantic): ...
Cascon, Helena Matthews; Bezerra, Luís Ernesto Arruda; Barroso, Cristiane Xerez; Rabay, Soraya Guimarães; Moreira, Ana karla; Rocha, Valesca PaulaPrior to Brazil's worst environmental disaster, caused by a mining dam collapse, we had carried out a study of the marine benthic macrofauna (11–51 m depth) under the influence of the Doce River. Our results showed significant diversity, in which mollusks, polychaetes, and crustaceans had the highest frequency, density, and abundance, represented by 162 families in summer and 173 in winter. Our results suggeste...
Biogeography of Brazilian prosobranch gastropods and their Atlantic relationships
Barroso, Cristiane Xerez; Lotufo, Tito Monteiro da Cruz; Matthews-Cascon, HelenaAim The present study uses marine prosobranchs from shallow waters (down to 200 m) as a model to determine biogeographical units along the Brazilian coast and to investigate changes in assemblages along the Western Atlantic. Location Western Atlantic Ocean. Methods The composition and species distribution of prosobranchs were determined using secondary data and information gathered from Brazilian scientific col...
An extended geographical distribution of Donax gemmula Morrison, 1971 (Bivalvia...
Barroso, Cristiane Xerez; Rabay, Soraya Guimarães; Passos, Flávio Dias; Matthews-Cascon, HelenaThis study provides the first record of Donax gemmula Morrison, 1971 (Bivalvia: Donacidae) from the Ceará State, Northeast Brazil; up to now it was only known from the Southeastern and Southern Brazilian coast. Shells larger than ~2 mm in length of this species can be distinguished from those of D. striatus Linnaeus, 1767. Both species were collected in the same beaches: Banco dos Cajuais and Pecém. The occurre...
Avaliação da disponibilidade de metais em sedimentos do Canal de Bertioga (Comp...
Soares, Marcelo de Oliveira; Barroso, Cristiane Xerez; Lima, Ítalo Cesar Camelo Soareshe South Atlantic Ocean is the youngest of the world’s oceans and one of the most important biodiversity hotspots; however, there is a lack of scientific knowledge about its ecological history. Here, we present the first results of a fossil invertebrate survey from the Rocas Atoll. By using radiometric dating (14C) and a survey of fossilized benthic invertebrates on this atoll, we provide new paleobiogeographic...
