Diferença entre dois métodos de coleta utilizados na captura de crustáceos decápodes em um rio da Estação Ecológica Juréia-Itatins, São Paulo
Provedor de dados: 76
Autores: Rocha,Sérgio Schwarz da.
Durante os anos 2000 e 2001 foram realizadas coletas sazonais de crustáceos decápodes em dois pontos de um rio na Estação Ecológica Juréia-Itatins, utilizando-se duas metodologias distintas (peneira e armadilha). Comparando-se ambos os métodos de coleta, foram constatadas diferenças quanto à composição e riqueza da carcinofauna capturada, grau de dominância e equitatividade, bem como tamanho e número de indivíduos coletados. Além disso, as razões sexuais de Macrobrachium acanthurus (Wiegmann, 1836) podem diferir dependendo do método de coleta utilizado. Devido à grande variedade de hábitats e hábitos dos crustáceos, pode-se inferir que, para um levantamento qualitativo e/ou quantitativo eficaz e apurado da comunidade de crustáceos decápodes dulcícolas de...

On one new genus and three new species of freshwater crabs (Crustacea: Decapoda: Brachyura: Potamidae and Grapsidae) from Lanjak-Entimau, Sarawak, East Malaysia, Borneo
Provedor de dados: 16
Autores: Ng, P.K.L.
The freshwater crabs obtained from the Lanjak-Entimau area in Sarawak, East Malaysia, Borneo, are reported upon. One new genus (Ibanum) and two new species of Potamidae (Ibanum aethes and Isolapotamon stuebingi) and a new species of Grapsidae (Geosesarma katibas) are described. The identity of Potamon (Geothelphusa) bicristatum De Man, 1899, orginally described from the upper Kapuas in Kalimantan is also clarified, and is here assigned to the new genus, Ibanum.

On a new species of Geosesarma de Man, 1892 (Crustacea: Decapoda: Brachyura: Grapsidae) from Chanthaburi Province, eastern Thailand
Provedor de dados: 16
Autores: Ng, P.K.L.; Naiyanetr, P.
A new species of terrestrial freshwater sesarmine crab (Decapoda: Brachyura), Geosesarma krathing spec, nov., is described from near a waterfall in Chanthaburi Province, eastern Thailand. This is the first record of the genus from that part of Thailand. The species is allied to G. peraccae (Nobili, 1903) from Singapore and southern Peninsular Malaysia, but differs in the form of the carapace and male first pleopod structure.

Phylogenetic and systematic position of Sesarma rubripes Rathbun, 1897 (Brachyura: Grapsidae)
Provedor de dados: 16
Autores: Niem, V.H.
The American grapsid crab Sesarma rubripes, classified as Metasesarma rubripes by Rathbun (1918), was compared with M. rousseauxi, the type species of Metasesarma, and was found to be different in a number of characters. On the other hand, S. rubripes is very close to those species of American Sesarma that are considered to be members of the subgenus Chiromantes. The characters common to S. rubripes and the American Chiromantes can be interpreted as synapomorphies by means of an outgroup comparison. Aratus pisonii and the West African Sesarma elegans are further members of the group in question and both share special derived characters with S. rubripes. As a consequence, S. rubripes should be returned to the genus Sesarma. It is recommended, however, to...

Desenvolvimento larval de Chasmagnathus granulata Dana (Crustacea, Decapoda, Grapsidae), em laboratório: I. estudo da morfologia de cerdas nas fases de zoea e megalopa e das variações dos padrões corporais da fase de megalopa
Provedor de dados: 104
Autores: Rieger,Paulo Juarez; Santos,Ana Lucia F.
The study of Chasmagnathus granulata Dana 1851 was done with the setae morphology point of view. The main objective of this description was to find differents kinds of morphologicals types of setae. During this work anomalous structures were found in megalopal phase, such as: many kinds of rostral and lateral spines, as well as many kinds of spines on the telson and one kind of dorsal spine which never was cited before in the literature concerning to this specie.

External factors determining breeding season in the red mangrove crab Goniopsis cruentata (Latreille) (Crustacea, Brachyura, Grapsidae) on the São Paulo State northern coast, Brazil
Provedor de dados: 104
Autores: Cobo,Valter José; Fransozo,Adilson.
This study evaluated the influence of the water and air temperatures, pluviosity and photoperiod on the breeding season of Goniopsis cruentata (Latreille, 1803), in Ubatuba littoral, southeastern Brazilian coast. Monthly collections were conducted out from January/95 to December/96 in an estuarine area from 23º29'10"-23º29'45"S to 45º09'10"-45º10'00"W. Water and air temperature variation showed the highest correlation coefficient with the frequency of ovigerous females, r² = 0.73 and 0.68, respectively. However, an analysis of the set of environmental variables, revealed the photoperiod as the factor of highest association with the ovigerous frequency (r² = 0.68). This degree of association allow us to suggest that the breeding season duration of G....

Provedor de dados: 104
Autores: Silva,Zilanda de Souza; Oshiro,Lídia Miyako Yoshii.
The objective of this study was to get some knowledge about the reproductive aspects of Goniopsis cruentata (Latreille, 1803), concerning through sex ratio, morphological sexual maturity, reproductive period, fecundity and eggs size. The crabs were collected monthly in Itacuruçá's Mangroves from November, 1997 to November, 1998. Four hundred and seven crabs were caught and they were 47% males, 36% females and 17% ovigerous females. The sex ratio was 1:1.13 (male:female) (X²= 1.54, p &gt; 0.05). The relation of abdomen width (AW) and carapace width (CW) in females showed a positive allometric grow (b = 1.36), it suggests the size onset of maturity occur from 26.0 a 29.0 mm (CW) in females. The ovigerous females occured during all the research period, except...

Zoeal morphology of Pachygrapsus transversus (Gibbes) (Decapoda, Grapsidae) reared in the laboratory
Provedor de dados: 104
Autores: Brossi-Garcia,Ana Luiza; Rodrigues,Misael Domingues.
Ovigerous females of Pachygrapsus transversus (Gibbes, 1850) were collected on the Praia Dura and Saco da Ribeira beaches, Ubatuba, São Paulo, Brazil. Larvae were individually reared in a climatic room at 25ºC temperature, salinities of 28, 32 and 35‰ and under natural photoperiod conditions. The best rearing results were observed at 35%o salinity. Seven zoeal instars were observed, drawing and described in detail. The data are compared with those obtained for P. gracilis (Saussure, 1858).

Provedor de dados: 104
Autores: Rieger,Paulo Juarez; Vieira,Rony Roberto Ramos.
The larval development of Cyrtograpsus angulatus Dana, 1851 was studied in laboratory through eggs hatched from ovigerous females collected in mole of Rio Grande, Rio Grande, State of Rio Grande do Sul, Brazil. Three experiments (A, B, C) were carried out involving 250 larvae, derived from three ovigerous females. The experiments A and B, were carried in a climatically box with temperature among 22 and 25ºC, and salinity among 32 and 34‰. The experiment C in a room without controlled temperature, in a constant salinity of 30‰. The larvae were maintained individually and food consisted of rotifers Brachionus plicatillis Müller, 1786 and microscope algae Tetraselmis sp. The development of C. angulatus Dana, 1851 comprises five stages of zoea and one...

Autores: Rieger,Paulo Juarez; Beltrão,Roberta.
This paper describes the first nine juvenile stages of Cyrtograpsus angulatus Dana, 1851 obtained in laboratory conditions from three ovigerous females collected at "Molhes da Barra", Rio Grande, Brazil (32ºS and 52ºW). The main morphological features, the secondary sexual characters and the gills ontogeny were observed. Twenty one individuals reached until the ninth juvenile stage. Sexual dimorphism can be verified from the fourth juvenile stage and the number of gills are complete at the second juvenile stage.
