Marine hardbottom environments in the beaches of Ceará state, equatorial coast ...

This 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...

Gestão de unidades de conservação marinhas: o caso do Parque Estadual Marinho d...

The importance Protected Areas as a tool for conservation and sustainable resource use has been widely acknowledged. Historically, the concept and management of protected areas was developed with the focus on terrestrial environments. In the past few decades, the Marine Protected Areas (MPA) has gained increasing attention in regards to the management of coastal and oceanic ecosystems. In this context, the envi...

Predicted shifts in the distributions of Atlantic reef-building corals in the f...

Molecular evidences confirm the taxonomic separation of two sympatric congeneri...

A 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...

Biogeography of Brazilian prosobranch gastropods and their Atlantic relationships

Aim 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...

A biogeographic approach to the insular marine ‘prosobranch’ gastropods from th...

The MacArthur & Wilson theory of island biogeography predicts that the balance between immigration and extinction rates results from the size and degree of isolation of the island. Here, we test this assumption using data from the marine gastropods of Brazilian oceanic islands. Species lists were compiled for Rocas Atoll, the Fernando de Noronha Archipelago, the Sa˜o Pedro and Sa˜o Paulo Archipelago and Trindad...

Primeiro registro de Pomadasys Ramosus Poey, 1860 (Perciformes: Haemulidae) par...

This paper is the first record of Pomadasys ramosus in Ceará State coast, Brazil. Fish of this species present pisciforme shape, prolongated, and compressed laterally body, such as all species of the Haemulidae family. The P. ramosus especimen described in this paper was collected in the Acaraú River estuary (02º52’15.8"S - 40º07’47.2"W). The individual was captured at 7,5 m depth inside the estuary. A monofila...
