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 ...
Purification, biochemical characterization, and amino acid sequence of a novel ...
Carneiro, Rômulo Farias; Torres, Renato Cézar Farias; Chaves, Renata Pinheiro; Vasconcelos, Mayron Alves de; Sousa, Bruno Lopes deA new lectin from Aplysia dactylomela eggs (ADEL) was isolated by affinity chromatography on HClactivated Sepharose™ media. Hemagglutination caused by ADEL was inhibited by several galactosides, mainly galacturonic acid (Ka = 6.05 × 106 M−1 ). The primary structure of ADEL consists of 217 residues, including 11 halfcystines involved in five intrachain and one interchain disulfide bond, resulting in a molecular ...
Inferência de padrões de distribuição da família Veneridae (Mollusca, Bivalvia)...
Rocha, Valesca Paula; Matthews-Cascon, HelenaVeneridae is one of the largest families of Recent, also one of the most diverse within Bivalvia, being found in marine and estuarine environments. Biogeographic studies are important for the management and conservation of the biodiversity. This paper aims at inferring the latitudinal and longitudinal distribution patterns, gathering and listing Vene-ridae composition for the Brazilian coast through secondary d...

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...
Neritic Jellyfishes (Cnidaria: Cubozoa and Scyphozoa) from the coast of Rio Gra...
Soares, Marcelo de Oliveira; Morandini, André Carrara; Matthews-Cascon, HelenaFor the entire Brazilian coast, there are 22 published records of scyphozoans. On the other hand, only 35 species of cubozoans were described worldwide, four of them reported for the Brazilian coast. However, little is known about the species of cubozoans and scyphozoans in the Northeastern states of Brazil. The aim of this study was to perform a survey of the jellyfish (Cnidaria: Cubozoa and Scyphozoa) on the ...
Spawn and larval development of Pleuroploca aurantiaca (Lamarck, 1816) (Gastrop...
Meirelles, Carlos A. O.; Matthews-Cascon, HelenaSpawn and larval development stages of Pleuroploca aurantiaca from northeast Brazil are described. Thereproductive period lasted from August to December, with a peak in November. Spawn masses were composed of 29 ±3vase-shaped capsules which measured 9 ±1 mm (n = 30) in length and 4.5 ±0.5 mm (n = 30) in width. The exit plug waslocated on the apical area and measured 2.5 ±0.5 mm (n = 30) in diameter. Each capsul...
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...
