Dieta de espécies de Anostomidae (Teleostei, Characiformes) na área de influência do reservatório de Manso, Mato Grosso, Brasil
Provedor de dados: 76
Autores: Balassa,Graziela Custodio; Fugi,Rosemara; Hahn,Norma Segatti; Galina,André Beal.
The diet of four species of Anostomidae (Leporinus friderici Bloch, 1794, L. striatus Kner, 1858, L. elongatus Valenciennes, 1849 and Leporinus sp.) were investigated in the Manso Reservoir, Mato Grosso State, Brazil. Fish were sampled in three sites: upriver, in the main body of the reservoir, and below the dam. Were analized 276 stomachs. The diet was evaluated using the frequency of ocorrence and volumetric methods. Leporinus friderici showed tendency to herbivory, mainly in the upriver site. In the reservoir and below the dam, it consumed large quantities of fish; Isoptera only in the reservoir. Leporinus striatus and L. elongatus have similar diets, consuming Chironomidae larvae (Diptera), whereas Leporinus sp. was more generalist, feeding similar...

Alimentação de quatro espécies de Leporinus (Characiformes, Anostomidae) durante a formação de um reservatório no sudeste do Brasil
Provedor de dados: 76
Autores: Durães,Renata; Pompeu,Paulo dos Santos; Godinho,Alexandre Lima.
The study reports the changes ocurred in feeding ecology of fish species during a tropical river reservoir formation. It was analysed the stomachal contents of 399 individuals belonging to four species of genus Leporinus (L. elongatus Valenciennes, 1849, n=157; L.friderici (Bloch, 1794), n=87; L. octofasciatus Steindachner, 1917, n=107; L.amblyrhynchus Garavello &amp;amp; Britski, 1987, n=48) during formation of Nova Ponte reservoir, State of Minas Gerais, Brazil, in 1993 and 1994. Specimens were separated by sampling period, according with the rate of filling of the reservoir, and standard lenght classes. The species had included in diet vegetal and animal items of autochtone and alochtone origin in several proportions. L. amblyrhynchus fed on basically...

Enzymatic polymorphism study as help for constitution of initial broodstock for a new cultivated finfish species.
Provedor de dados: 5
Autores: Renno, J; Luquet, P.
Leporinus friderici is a South American promising species for fish culture. In French Guiana the "morphological species", L. friderici, L. granti, L. lebaili and L. affinis steyermarki are found. Their identification is sometimes difficult on usual criterion. To constitute an initial broodstock of L. friderici from local wild populations, the genetic structure of these species was studied. Fifteen enzyme systems, representing twenty loci, were screened.

Arrhinolemur scalabrinii Ameghino, 1898, of the late Miocene : a taxonomic journey from the Mammalia to the Anostomidae (Ostariophysi: Characiformes)
Provedor de dados: 83
Autores: Bogan,Sergio; Sidlauskas,Brian; Vari,Richard P; Agnolin,Federico.
The fossil species Arrhinolemur scalabrinii, which was described from late Miocene deposits of Entre Ríos, Argentina, is reevaluated. Whereas the species was originally placed in the Primates (Mammalia) and later made the unique member of the order Arrhinolemuroidea within the Mammalia, our analysis indicates that the specimen is rather a fish of the genus Leporinus, family Anostomidae (Characiformes). The species is redescribed, and the characters that support its new generic assignment are discussed.

Fauna parasitária de Leporinus lacustris e Leporinus friderici (Characiformes, Anostomidae) da planície de inundação do alto rio Paraná, Brasil - DOI: 10.4025/actascibiolsci.v28i3.228

Foram investigadas as faunas parasitárias de Leporinus lacustris e Leporinus friderici da planície de inundação do Alto rio Paraná, Brasil, objetivando compará-las em composição e estrutura das comunidades seguindo-se metodologias usuais no estudo dos parasitas. Foram observados alguns padrões e as faunas podem ser consideradas semelhantes em estrutura. A principal diferença nas faunas parasitárias refere-se às taxas diferenciais de utilização das espécies hospedeiras por algumas espécies parasitas em comum, representadas pela abundância. Esse indicador diferiu entre as espécies de peixes mostrando que, apesar delas serem hospedeiras apropriadas, sua exploração ocorre de forma distinta.
