Provedor de dados: 76
Autores: Oliveir,Alexandre; Pinto,Taciana K.; Santos,Débora P. D.; D'Incao,Fernando.
Na região estuarina da Lagoa dos Patos, o siri-azul Callinectes sapidus Rathbun, 1869 é o mais abundante dentre as espécies do gênero. Apesar do siri-azul exercer influência sobre as comunidades bentônicas, por ser considerado um predador do topo da cadeia alimentar, não existem muitos estudos sobre aspectos ecológicos, inclusive sobre a composição e variabilidade sazonal de sua dieta natural, neste estuário. O objetivo principal deste estudo foi investigar a composição da dieta do siri-azul, evidenciando possíveis relações com a comunidade bentônica da região estuarina da Lagoa dos Patos. O período de estudo foi de março de 2003 a março de 2004, com coletas bimestrais. Os organismos foram coletados com auxílio de rede de arrasto de fundo, com malha de 13...

Comparação do crescimento entre Callinectes sapidus (Crustacea, Decapoda, Portunidae) coletados em campo e mantidos em condições contoladas
Provedor de dados: 76
Autores: Rodrigues,Marcos A.; D'Incao,Fernando.
Devido à falta de estruturas rígidas para determinação de idade em crustáceos, métodos que se baseiam na determinação de idade através da distribuição da freqüência de comprimentos são comumente utilizados. Neste trabalho, foi comparado o crescimento do siri-azul, Callinectes sapidus Rathbun, 1896, em laboratório e a partir de indivíduos de campo. Os indivíduos de laboratório, após a coleta, tiveram seu crescimento acompanhado individualmente. A temperatura foi mantida constante (25±2°C) e a salinidade a 20±5. Os indivíduos do campo foram coletados entre 2002 e 2004 em pontos pré-determinados no estuário da Laguna dos Patos, com rede de portas. A biometria, nos dois casos, constou da medida da largura da carapaça (LC mm). As estimativas das curvas de...

A new classification of the Xanthoidea sensu lato (Crustacea: Decapoda: Brachyura) based on phylogenetic analysis and traditional systematics and evaluation of all fossil Xanthoidea sensu lato
Provedor de dados: 16
Autores: Karasawa, H.; Schweitzer, C.E.
A phylogenetic analysis was conducted including representatives from all recognized extant and extinct families of the Xanthoidea sensu lato, resulting in one new family, Hypothalassiidae. Four xanthoid families are elevated to superfamily status, resulting in Carpilioidea, Pilumnoidoidea, Eriphioidea, Progeryonoidea, and Goneplacoidea, and numerous subfamilies are elevated to family status. The Mathildellidae is moved from the Goneplacidae to the Portunoidea. Diagnoses for all superfamilies and families discussed herein are provided, embracing characters typically used by biologists as well as readily fossilized features of the dorsal carapace, sternum, abdomen, and chelipeds. All genera known from the fossil record at one time referred to the Xanthidae...

Ovigerous females of Arenaeus cribrarius were collected at Ubatuba, São Paulo, and maintaining in aquaria under controlled temperature (25±1ºC), salinity (35±1‰) and photoperiod (12:12). A small sample of eggs was collected for each 24h, for morphological description, chromatic changes and biometric analysis throughout the embryonic development. Eight egg stages were photographed and had their small and large diameters measured under a microscope provided with camera lucida. The egg's shape was low elliptical during all the embryogenesis and showed size increase (24.4%) and volume (91.1 %), when the last stage were compared with the first one. According to mean egg diameter and volume, the eggs should be pooled in three different groups (1-3; 4-6; 7-8)...
