Polymorphic microsatellite DNA markers in the mangrove crab Ucides cordatus (Brachyura: Ocypodidae).
The isolation and characterization of the first polymorphic microsatellite markers for the mangrove crab Ucides cordatus are described. The number of alleles at each locus ranged from three to 25, mean of nine alleles, in 46 crabs captured in two Brazilian mangroves. The markers averaged high levels of observed (0.709 ± 0.183) and expected (0.716 ± 0.170) heterozygosities. Departures from H...
متن کاملAcute toxicity of sodium metabisulphite on mangrove crab Ucides cordatus (Decapoda, Ucididae).
The sodium metabisulphite salt is usually used in shrimp culture to prevent black spot. Unfortunately the toxicological effect of this xenobiotic in decapod crabs is unknown. Thus, the present study aims to investigate the sodium metabisulphite LC(50) - 96 h in the mangrove species Ucides cordatus. Crabs were collected in the tidal creek margins in Bragança estuarine and were submitted to preli...
متن کاملSexual Shape Dimorphism of the Mangrove Crab Ucides cordatus (Linnaeus, 1763) (Decapoda, Ucididae) Accessed through Geometric Morphometric
Sexual dimorphism is often observed in Crustaceans. Considering the great diversity of this subphylum, only few reports are found in the literature and most are mainly based on traditional morphometry. The present study uses geometric morphometrics analysis to identify sexual dimorphism by shape variation in the overexploited semiterrestrial crab Ucides cordatus, species with great social and e...
متن کاملPopulation biology of the mangrove crab Ucides cordatus (Decapoda: Ucididae) in an estuary from semiarid northeastern Brazil.
The mangrove crab Ucides cordatus is an important resource of estuarine regions along the Brazilian coast. U. cordatus is distributed from Florida, U.S.A., to the coast of Santa Catarina, Brazil. The species plays an important role in processing leaf litter in the mangroves, which optimizes the processes of energy transfer and nutrient cycling, and is considered a keystone species in the ecosys...
متن کاملEnvironmental perception of gatherers of the crab 'caranguejo-uçá' (Ucides cordatus, Decapoda, Brachyura) affecting their collection attitudes
Introduction Mangrove forests are productive ecosystems found along the coastal zones of Brazil, providing several profitable resources such as timber, medicinal products, natural dye, fish, crustaceans, and molluscs. For the littoral dwellers of Northeast Brazil, the Brachyura crabs are a major economic resource. The main species they commercialize are the 'goiamum' (Cardisoma guanhumi), 'siri...
