Última Karyotype description of possible new species of the Hypostomus ancistroides complex (Teleostei: Loricariidae) and other Hypostominae - doi: 10.4025/actascibiolsci.v34i2.9318 Biological Sciences Endo, Kátia Sayuri; Universidade Estadual de Maringá; Martinez, Emanuel Ricardo Monteiro; Universidade Estadual Paulista “Júlio de Mesquita Filho" / Botucatu-SP; Zawadzki, Claudio Henrique; Universidade Estadual de Maringa; Paiva, Luiz Ricardo de Souza; Universidade Estadual Paulista “Júlio de Mesquita Filho" / Botucatu-SP; Júlio Júnior, Horácio Ferreira; Universidade Estadual de Maringá. Cytogenetic analyses were performed in four species of the Hypostominae subfamily, three from Hypostomus (Hypostomini) genus and Rhinelepis aspera (Rhinelepini). Three populations of Hypostomus ancistroides were analyzed, which had 2n=68 chromosomes, but presented different karyotype formulas. Hypostomus regani and H. strigaticeps, both from Ivaí river, showed 2n=72 chromosomes with two distinct cytotypes. In turn, R. aspera of the upper Paraná river basin presented 2n=54 chromosome. Multiple Nucleolar Organizer Regions (NORs) have been evidenced by silver nitrate staining in species of Hypostomus and single NOR in R. aspera. The observed variation in the chromosome number and the marked variability in karyotype formulas and NORs reveal a certain amount of...

The aim of this study was to verify structure patterns in fish assemblages in mountain streams of the Rio Tibagi basin through the characterization of spatial and temporal variations in the composition of fish species. Samples were collected in three segments of the Varanal, João Pinheiro and Rio Preto streams. We collected 1154 specimens belonging to 21 species. The most abundant orders were Characiformes (59.01 ± 2.84%) and Siluriformes (39.34 ± 2.82%). Phalloceros harpagos was the most abundant species with 433 individuals, followed by Trichomycterus aff.davisi, with 292 individuals. No temporal variations (between seasons) were detected, but the cluster analysis suggests a separation of species composition between the segments closer to the headwaters...

This study aimed to evaluate the fish fauna composition and distribution in different environments, up- and downstream the Gavião Peixoto Dam, in the Jacaré-Guaçu River basin. Most of the sampled ichthyofauna is autochthonous, and the majority of the species belongs to the orders Characiformes and Siluriformes. The order Characiformes comprised most of the specimens caught, Astyanax altiparanae being the most abundant species. All the studied environments were characterized by the massive occurrence of accidental species and low similarity between their ichthyofauna. In general, a greater number of species and higher values of the diversity index were observed downstream of the dam. The fish diversity in the studied habitats was positively correlated with...

Ano: 2011 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1676-06032011000100010 Short-term cold storage of sperm from six neotropical characiformes fishes BABT Marques,Simone; Godinho,Hugo Pereira. Sperm of the following Neotropical Characiformes fish species were tested for cold storage: Brycon lundii, Piaractus mesopotamicus, Leporinus elongatus, Leporinus friderici, Prochilodus lineatus and Prochilodus marggravii. Each sperm sample was split into two aliquots. The first was placed into a plastic bag with air or oxygen and the second, in a plastic tube with air. The samples were maintained at temperatures between 1.7-4.9 ºC. The rate of sperm motility was estimated using a 50 mM NaCl solution as the activating solution. The shortest sperm storage duration (7 h) was recorded for L. friderici, when the sperm motility rate reached ~ 30%, whereas the longest duration (20 h) was obtained with the sperm of P. lineatus. A fertilisation test using... Tipo: Info:eu-repo/semantics/article Palavras-chave: Cool storage of sperm; Sperm motility; Semen; Neotropical fishes.
