Abstract The upper rio Paraná basin drains the most developed and environmentally degraded region in South America: Brazilian southeast. While it is one of well-known Neotropical fish assemblages, also threatened by anthropic activity. Urbanization, deforestation, dam construction, invasive species, water pollution not only reduce living area species but alter our perception its biotic elements. Such changes are so profound pervasive that raise uncertainties about native or non-native status...
É apresentada uma síntese sobre os peixes do Alto Paraná, com base em dados de coleções, literatura e novas coletas. Trezentas dez espécies, 11 ordens 38 famílias, são referidas para a drenagem, aumentando significativamente números anteriores. Dentre as espécies da área, 236 (76,1%) autóctones, 67 (21,6%) alóctones sete (2,3%) exóticas. As principais causas ocorrência não nativas (alóctones exóticas) foram dispersão partir baixo após construção Reservatório Itaipu o escape pisciculturas. A...
An annotated catalog of the type specimens deposited at fish collection “Universidade Estadual Paulista, Câm-pus de São José do Rio Preto”, Paulo, Brazil (DZSJRP), is herein presented for consultation and scientific information. The DZSJRP comprised by 154 lots 4,993 specimens, 18 which are holotypes, include a total 53 species in six families. For each species, following data provided: current valid name, authority year description, locality holotype number (for those hosted DZSJRP), list...
The number of species Microlepidogaster recently increased considerably, the genus presently comprises six distributed in Paraná, São Francisco, and Jequitinhonha river basins. A new is herein described from upper Rio Francisco basin, which can be distinguished all congeners by having two exclusive features within genus: skin over swimbladder opening with to five reduced unperforated platelets, ventral laminar expansion coracoid enclosing completely or almost arrector fossa pectoral girdle....
Neste trabalho foi realizado um levantamento das espécies de peixes riacho que ocorrem no Parque Estadual Morro do Diabo. Quatro riachos foram amostrados, primeira a segunda ordem, onde coletadas 22 espécies, pertencentes cinco ordens e 11 famílias, num total 1.573 indivíduos. Foi registrado o predomínio da Ordem Siluriformes, seguida por Characiformes. Com base em aspectos gerais biologia peixes, as mesmas classificadas oito guildas. De modo geral, estudadas são capazes utilizar diversos...
A fish survey in 35 stream reaches (from 1st to 3rd order) with physicochemical and habitat assessment the São José dos Dourados system, southeastern Brazil, was conducted. Most of basin land cover (77.4%) is used for pasture. From sampled reaches, 24 were good quality, 10 fair only one poor quality. showed that considered fair, 22 poor, 3 very poor. Fifty species collected their abundances strong correlation descriptors. In addition between abundance habitat, some also optimal distribution...
O ponto médio de cada trecho foi georreferenciado via satélite com receptor GPS e o uso metodologia padronizada coleta dados ambientais peixes (baseada principalmente na pesca elétrica), possibilitou a obtenção das seguintes informações em local: 1) composição taxonômica da ictiofauna contribuição, termos número indivíduos biomassa, espécie para local como um todo; 2) documentação fotográfica espécimes representativos coletada sua coloração natural; 3) descrição ambiente coletado,...
A new Hasemania species is described from the headwaters of rio Uberaba, Grande basin, State Minas Gerais, Brazil. The distinguished its congeners by a combination black, vertically-elongate humeral spot, single ossification in position primitively occupied infraorbitals four and five, teeth on inner series premaxilla, scales covering anal-fin base. crenuchoides redescribed known geographic distribution extended; it can be differentiated other genus black ii,8 dorsal-fin rays, 11-14 branched...
The structure of the fish communities a pool and rapid in ribeirão Santa Bárbara is described. This stream 5th order direct tributary rio Tietê system upper Paraná. Thirty three species, from nine families orders, were referred two mesohabitats: with 31 18. Orders Characiformes, Siluriformes, Perciformes presented greatest number species mesohabitats. Characidae Loricariidae most specious, followed by Cichlidae pool, Parodontidae rapid. Most accidental, 17 10 rapid, only six constant...

Sexual dimorphism present, with males being more than females having bony hooks in anal pelvic fins, which their terminal portions.

Marginal lagoons are natural nurseries of commercially important fish species and preferential habitats for sedentary small-sized species. The composition abundance communities in seasonally isolated the Turvo River, qualitative quantitative changes dry rainy seasons, as well their relationship with environmental factors, were investigated. material was sampled both seasons six marginal lagoons. Ichthyofauna studied through richness, diversity, evenness, similarities, ecological associations...
