Cytogenetic characterization of Hoplias malabaricus (Bloch, 1794) from the Ctalamochita River (Córdoba, Argentina) : first evidence for southernmost populations of this species complex and comments on its biogeography
Grassi, Diego Javier; Swarça, Ana Claudia; Abdala Dergam, Jorge; Pastori, María Cristina; Fenocchio, Alberto Sergio (Pensoft, 2017-01-09)Hoplias malabaricus (Bloch, 1794), a predatory freshwater fish with a wide distribution throughout South America, represents a species complex with seven well characterized karyomorphs at the cytogenetic level. Although ... -
Cytogenetic studies in the redtail catfish, Phractocephalus hemioliopterus (Bloch & Schneider, 1801) (Siluriformes, Pimelodidae) a giant fish from Amazon basin
Swarça, Ana Claudia; Dias, Ana Lucia; Fenocchio, Alberto Sergio (Pensoft, 2017-03-06)The objective of this study was to cytogenetically analyze Phractocephalus hemioliopterus comparing the findings with other data to infer relationships among Pimelodidae species. The results revealed a diploid number of ... -
Cytogenetic trends in two families of the neotropical catfishes : Heptapteridae and Pseudopimelodidae (siluriformes)
González Gouveia, Juceli; Oliveira de Moraes-Manécolo, Vivian Patrícia; Swarça, Ana Claudia; Fenocchio, Alberto Sergio; Giuliano-Caetano, Lucia; Dias, Ana Lucia (Mary Ann Liebert, Inc., 2018-09-05)Several neotropical Siluriformes groups suffered important taxonomic revisions based on the evaluation of morphological and molecular characteristics that allow the construction of new phylogenetic hypothesis. In the present ... -
First cytogenetic characterization of Loricaria simillima (Loricariidae, Siluriformes) from Paraná River (Argentina) with emphasis in cytotaxonomy of Loricaria
Benitez, Mauricio Fabián; Pastori, María Cristina; Garrido, Gladys Graciela; Takagui, Fábio Hiroshi; Giuliano-Caetano, Lucia; Fenocchio, Alberto Sergio (Taylor & Francis, 2016-11-30)This work aims to establish some cytogenetic characteristics of Loricaria simillima from Paraná River. The obtained results show that L. simillima has a 2n = 64 diploid number, with 12 metacentric, 12 sub-metacentric and ... -
First report of B chromosomes in three neotropical thorny catfishes (Siluriformes, Doradidae)
Takagui, Fábio Hiroshi; Dias, Ana Lucia; Olivan Birindelli, José Luís; Swarça, Ana Claudia; Da Rosa, Renata; Lui, Roberto Laridondo; Fenocchio, Alberto Sergio; Giuliano-Caetano, Lucia (Pensoft, 2017-01-09)The family Doradidae (Siluriformes) is an important group of fishes endemic to freshwater ecosystems in South America. Some cytogenetic studies have been conducted focused on the group; however, there are no reports on the ...
