Associações entre as biomassas de peixes Sciaenidae (Teleostei: Perciformes) e de camarões Penaeoidea (Decapoda: Dendrobranchiata) no litoral norte do Estado de São Paulo
(Biota Neotropica, 2008-03-01) [Artigo]
Visando analisar as associações entre as biomassas de peixes Sciaenidae e de camarões Penaeoidea, foram feitas amostragens com barco de arrasto nas quatro estações do ano de 2001, em um gradiente de profundidade, nas regiões ...
Inferring population connectivity across the range of distribution of the stiletto shrimp Artemesia longinaris Spence Bate, 1888 (Decapoda, Penaeidae) from DNA barcoding: implications for fishery management
(Zookeys, 2014-01-01) [Artigo]
Artemesia longinaris is a marine shrimp endemic to the southwestern Atlantic and distributed from Atafona, Rio de Janeiro (Brazil) to Rawson, Chubut (Argentina). In recent years, this species has become an important target ...
Reproduction and recruitment of the seabob shrimp: a threatened exploitation species in southeastern of Brazil
(Boletim Do Instituto De Pesca, 2015-01-01) [Artigo]
This study evaluated the reproductive period and recruitment of the threatened exploitation shrimp Xiphopenaeus kroyeri (Heller) in the southeast coast of Brazil. Monthly samples were carried out from March 2008 to February ...
Isolation and characterization of microsatellite loci in the Neotropical fish Astyanax altiparanae (Teleostei: Characiformes) and cross-species amplification
(Journal of Genetics, 2012-04-01) [Artigo]
Common Descent of B Chromosomes in Two Species of the Fish Genus Prochilodus (Characiformes, Prochilodontidae)
(Cytogenetic and Genome Research, 2013-01-01) [Artigo]
To ascertain the origin of B chromosomes in 2 fish species of the genus Prochilodus, i.e. P. lineatus and P. nigricans, we microdissected them and generated B-specific DNA probes. These probes were used to perform chromosome ...
Morphology of the first larval stage of Macrobrachium brasiliense (Heller, 1868) (Caridea: Palaemonidae)
(Nauplius, 2011-08-01) [Artigo]
In this paper, we describe and illustrate the morphology of the first larval stage of the prawn Macrobrachium brasiliense. Two ovigerous females were obtained in a stream environment, which belongs to Paraná River Basin, ...
Geographical variation in fecundity and reproductive investment of Loxopagurus loxochelis (Decapoda: Anomura: Diogenidae) along the south-eastern coast of Brazil
(Invertebrate Reproduction & Development, 2019-01-02) [Artigo]
We aimed to study the fecundity and reproductive investment of Loxopagurus loxochelis under different environmental conditions. In total, 67 ovigerous females were analyzed, 20 from Macae, 26 from Ubatuba and 21 from ...
The complete mitochondrial genome sequences of five Otophysi species (Vertebrata, Teleostei)
(Mitochondrial Dna Part B-resources, 2019-07-03) [Artigo]
Complete mitochondrial genomes of the characiform fishes Astyanax fasciatus, Astyanax altiparanae, Hoplias malabaricus (Karyomorph A) and the Gymnotiformes species Gymnotus sylvius and Gymnotus cuia were characterized in ...
Identification of the shark species Rhizoprionodon lalandii and R-porosus (Elasmobranchii, Carcharhinidae) by multiplex PCR and PCR-RFLP techniques
(Molecular Ecology Resources, 2009-05-01) [Artigo]
Rhizoprionodon lalandii and R. porosus are widely distributed along the Atlantic coast of the Americas, living close to coastal areas and therefore frequently captured by seaboard fisheries. However, morphological ...
Origin of B chromosomes in the genus Astyanax (Characiformes, Characidae) and the limits of chromosome painting
(Molecular Genetics And Genomics, 2016-06-01) [Artigo]
Eukaryote genomes are frequently burdened with the presence of supernumerary (B) chromosomes. Their origin is frequently investigated by chromosome painting, under the hypothesis that sharing the repetitive DNA sequences ...
