The relationship between environmental variation and species abundance in shrimp community (Crustacea: Decapoda: Penaeoidea) in south-eastern Brazil
The low overall association between environmental parameters and shrimp abundance patterns indicates that each studied species might have responded idiosyncratically to environmental variation, such that a general community-level response was not apparent. Expand
Ecological distribution of the shrimp Pleoticus muelleri (Bate, 1888) (Decapoda: Penaeoidea) in southeastern Brazil
The high abundance of P. muelleri observed in the southern part of the region studied was related to a sediments with a higher percentage of silt and clay, and temperature and the type of sediment were determinant factors in the distribution in this region. Expand
Comparative research performance of top universities from the northeastern Brazil on three pharmacological disciplines as seen in scopus database
This research characterized and compared the research performance of 15 universities from Northeastern Brazil, in which 13 were among the top Universities of the Latin America, and showed where each of these universities stands, helpful in identifying potential collaborators in these areas of knowledge.

Shrimps from the Santana Group (Cretaceous: Albian): new species (Crustacea: Decapoda: Dendrobranchiata) and new record (Crustacea: Decapoda: Caridea).
The fossil shrimp Araripenaeus timidus n. gen. n. sp. is the first fossil Penaeoidea from Brazil. Here, we describe, illustrate and compare it with Paleomattea deliciosa, a fossil SergestoideaExpand
A new fossil caridean shrimp (Crustacea: Decapoda) from the Cretaceous (Albian) of the Romualdo Formation, Araripe Basin, northeastern Brazil.
A new fossil caridean shrimp, Kellnerius jamacaruensis n. gen. n. sp., of the early Cretaceous (Albian) from the Romualdo Formation, Araripe Basin, northeastern Brazil is described and illustrated.Expand
Reproductive Biology of Panulirus echinatus (Crustacea: Palinuridae) from São Pedro and São Paulo Archipelago, Brazil
The macro- and microscopic determinations of the existence of six gonadal development stages for females were possible and for males only tree stages of developmental stages could be determined by microscopy. Expand
New records of Stenopus hispidus Olivier (Stenopodidae) and Enoplometopus antillensis Lütken (Enoplometopidae) in the Southeastern Brazilian coast
This investigation provides new records extending southward the distribution of two important aquarium trade species in Brazil, Stenopus hispidus and Enoplometopus antillensis. Four specimens of S.Expand
Occurrence of Dendrocephalus brasiliensis Pesta, 1921 (Crustacea, Anostraca) in the Caras river, southern Ceara, Brazil.
Occurrence of Dendrocephalus brasiliensis Pesta, 1921 (Crustacea, Anostraca) in the Caras river, southern Ceara, Brazil. The specimens were collected in March and April 2014. The new occurrenceExpand
Large-field electron imaging and X-ray elemental mapping unveil the morphology, structure, and fractal features of a Cretaceous fossil at the centimeter scale.
A scanning electron microscopy approach that detected backscattered electrons (BSEs) and X-rays (from ionization processes) along a large-field (LF) scan, applied on a Cretaceous fossil of a shrimp, indicated a rare fossilization event observed for the first time in fossils from the Araripe Sedimentary Basin.

A new species of Chaceon Manning & Holthuis, 1989, from the southwestern Atlantic, with a key to the western Atlantic species (Crustacea, Decapoda, Geryonidae)
A new species of the deep-water crab genus Chaceon Manning & Holthuis, 1989, is described from southwestern Atlantic, which can be readily differentiated in having the dactyli of P2-P5 laterally compressed, instead of being dorsoventrally depressed. Expand
