Abstract:

The development stages of male and female gonads in the freshwater crab Sylviocarcinus pictus (H. Milne Eduards, 1853) were described through macroscopic and microscopic (histology) examinations. The histological description was based on 40 specimens (20 each sex). Four gonadal development stages were found for females: immature, ripening, mature and spawned. The following female cells were found: ovogonia, oocytes in initial vitellogenesis, oocytes in advanced vitellogenesis, follicular cells and post-ovulatory follicles. Three development stages were found for males: immature, maturing and m

Durante o período de cheia, abril e maio de 2021, foram coletados 122 camarões: 104 da família Palaemonidae e 18 da Euryrhynchidae. E 18 caranguejos da família Trichodactylidae: 8 do gênero Sylviocarcinus e 10 do Valdivia. As coletas foram realizadas em seis pontos no baixo rio Branco, dentro e fora da “Estação Ecológica do Niquiá.” Em cada ponto a amostragem foi de 4 horas: nas áreas de inundação, macrófitas aquáticas, raízes e gramíneas submersas, praias, margens das barrancas e serrapilheira submersa. Para captura dos crustáceos foram utilizadas armadilhas de espera tipo covo, matapi, puçás

Abstract:

New sampling programs have extended the distribution of three species of freshwater crabs (family Trichodactylidae): Dilocarcinus septemdentatus and Sylviocarcinus pictus from the Amazon basin to southern South America, and S. australis, from the north of Argentina southwards. The three species are now found in the floodplain of the middle Paraná River (31°39'S, 60°45'W). The extension of their distribution is approximately 500 km and 2000 km further south. The number of freshwater crab species in the alluvial valley of the Paraná River has increased by 30% with these new records.

Abstract This study investigated the resistance to desiccation of two species of freshwater crabs, Dilocarcinus pagei and Sylviocarcinus pictus. Dilocarcinus pagei survived almost twice as long as S. pictus, 127 ± 82.4 h and 69 ± 17.5 h, respectively. The females of both species survived longer than the males and the females of D. pagei survived longer than the females of S. pictus. Water loss until death was on average 30.12 ± 11.79% for D. pagei and 42.59 ± 7.49% for S. pictus. Dilocarcinus pagei showed a lower water loss than S. pictus until death and large S. pictus females and small D. pa

Abstract:

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, mo

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 pro

Sylviocarcinus pictus is a South American freshwater crab recently recorded for the first time in the Caatinga biome. Our objective was to characterize the population and reproductive biology of S. pictus from the semi-arid northeastern region of Brazil and verify the influence of seasonal environmental changes in this population. The crabs were collected from a stretch of Guaribas River, PI, Brazil, every month between October 2013 and September 2014. The crabs were identified, sexed and the carapace width (CW) was measured. Physiological sexual maturity was determined based on the gonadal de

The study was conducted at four collection sites distributed along the mouth of the Amazon River between the months of January/2009 and January/2010. The animals were caught using handcrafted traps called "matapi", which are used by prawn fisherman in the region. Twenty matapis were used at each collection site. A total of 145 specimens were captured and six species were identified, all belonging to the Trichodactylidae family - Sylviocarcinus maldonado

Abstract:

AbstractSylviocarcinus pictus is a freshwater crab widely distributed across the Amazon basin and coastal basins of northern South America. In the Xingu River basin, Pará, Brazil, the species is found from its middle portion up to the confluence with the Amazon River. This extensive distribution led to questions about the influence of the Volta Grande do Xingu rapids on genetic diversification between populations above and below this area. To explore this hypothesis, 39 mitochondrial gene sequences (COI and 16S rRNA) from 22 samples collected from both areas were analysed in a phylogeographic
