Morphometric variability in populations of Palaemonetes spp. (Crustacea, Decapoda, Palaemonidae) from the Peruvian and Brazilian Amazon Basin
Provedor de dados: Iheringia Série Zoologia
Autores: García-Dávila,Carmen Rosa; Magalhães,Célio; Guerrero,José Camilo Hurtado.
Morphometric variability among shrimp populations of the genus Palaemonetes Heller, 1869 from seven lakes (Huanayo and Urcococha, in Peru; Amanã, Mamirauá, Camaleão, Cristalino e Iruçanga, in Brasil) in the Amazon Basin, presumably belonging to Palaemonetes carteri Gordon, 1935 and Palaemonetes ivonicus Holthuis, 1950, were studied. The morphometric studies were carried out from the ratios obtained from the morphometric characters. Multivariated analysis (Principal Components Analysis-PCA, Discriminant Function Analysis and Cluster Analysis) were applied over the ratios. Intra- and interpopulation variations of the rostrum teeth, and the number of spines in the male appendix, were analyzed through descriptive statistics and bivariate analysis (Spearman...

Morfología comparada del esqueleto axial en la familia de cangrejos de agua dulce Trichodactylidae (Crustacea: Decapoda: Brachyura)
Provedor de dados: Papéis Avulsos de Zoologia
Autores: Pedraza,Manuel; Magalhães,Célio; Tavares,Marcos.
El esqueleto axial es una estructura compleja de origen cuticular, formada a partir de las láminas esclerotizadas de los esternitos y pleuritos torácicos así como por sus invaginaciones internas. Los caracteres de la parte ventral del esqueleto axial, que se reflejan externamente en las líneas de sutura del esternón torácico, son criterios importantes en el actual sistema de supragenerico de Trichodactylidae: (Trichodactylinae y Dilocarcininae (Dilocarcinini + Valdiviini)). Con el objetivo de probar esa hipótesis de clasificación fue realizado el estudio anatómico del esqueleto axial de 43 individuos adultos, tanto machos como hembras, pertenecientes a 17 especies de 10 géneros de Trichodactylidae. Para la preparación del material, los individuos fueron...

Offspring production in three freshwater crab species (Brachyura: Pseudothelphusidae) from the Amazon region and Central America
Provedor de dados: Revista Brasileira de Zoologia
Autores: Wehrtmann,Ingo S.; Magalhães,Célio; Hernáez,Patricio; Mantelatto,Fernando L.
Freshwater crabs are an important component of the fauna of limnic environments, and out of the two true freshwater crab families present in the Neotropics, Pseudothelphusidae is the most diverse. Considering the lack of information regarding reproductive features of neotropical freshwater crabs, we studied, for the first time, the fecundity and the presence of juveniles carried by females of two pseudothelphusids from the Amazon region - Kingsleya latifrons (Randall, 1840) and Kingsleya ytupora Magalhães, 1986 - and one from Central America - Potamocarcinus magnus (Rathbun, 1896). The two Kingsleya species produced relatively few (56-114) and large eggs (1.9-3.7 mm), typical for species with an abbreviated or direct development. Recently produced eggs...

Provedor de dados: Revista Brasileira de Zoologia
Autores: Lima-Gomes,Renata C.; Lima,Jô de Farias; Magalhães,Célio.
ABSTRACT The morphology of stomach ossicles of decapod crustaceans provides valuable information on their phylogeny and biology. We herein described ten new ossicles in the foreguts of two trichodactylid crabs, Sylviocarcinus pictus (H. Milne-Edwards, 1853) and Valdivia serrata White, 1847, in addition to previously described 38 ossicles, which are also recognized and listed. Five specimens each of S. pictus and V. serrata were selected for morphological analysis of gastric ossicles. The stomachs were obtained after removing the carapace, and they were fixed in 10% formalin for 24 hours. After this procedure, the stomachs were immersed in a solution of 10% Potassium Hydroxide (KOH) and heated to 100 °C during 60 minutes for tissue maceration. At this...

Recent advances in the biology of the Neotropical freshwater crab family Pseudothelphusidae (Crustacea, Decapoda, Brachyura)
Provedor de dados: Zoologia
Autores: Rodríguez,Gilberto; Magalhães,Célio.
Pseudothelphusidae is a well diversified group of Neotropical freshwater crabs currently comprising 40 genera and at least 255 species and subspecies. The biology of these crabs has been an active field of research in the last 20 years. The aim of the present contribution is to discuss the significance of the new knowledge on the biology of these freshwater crabs after September 1992, to stress the interconnection of the diverse lines of research and at the same time to suggest promising new lines of investigation. All taxa described from September 1992 to October 2004 are listed, including one genus, one subgenus, 62 species and five subspecies. The implications of this new knowledge on the taxonomy, systematic and biogeography of the family are commented.

Provedor de dados: Acta Amazonica
Autores: Magalhães,Célio; Barbosa,Ulysses C.; Py-Daniel,Victor.
The Yanomami are a group of South American Indians that live in the rainforest along the borderlands of Brazil and Venezuela. They depend on hunting, gardening and wild food for survival; crustaceans are a highly prized food item in their diet. Taxonomical and ethnozoological aspects of the Yanomami Indians of the Balawa-ú village, state of Amazonas, Brazil, related to the crustaceans are described. Information and specimens were obtained from August to December, 2003. Interviews were conducted with residents of the village and focused on questions about species exploited, indigenous names, modes of capture and use of the species. One shrimp species of the family Palaemonidae (Macrobrachium brasiliense) and two crab species of Trichodactylidae...

Autores: Magalhães,Célio.
Larval development of the freshwater palaemonid shrip Pseudopalaemon chryseus Kensley &amp; Walker, 1982 was studied in the laboratory from the offspring oof females collected in a lake of the lower Negro River system. Females carry few (14 to 43), large (1.86 + 0.13 x 1.29 + 0.06 mm), yolk-rich eggs. The species goes throught three larval stages without feeding and the main feature of its larval development is the presence of functional walking legs on hatching. Descriptions and illustrations of the three larval and first juvenile stages are presented.
