The opportunistic feeding and reproduction strategies of the annual fish Cynopoecilus melanotaenia (Cyprinodontiformes: Rivulidae) inhabiting ephemeral habitats on southern Brazil
The results confirmed the opportunistic character of the rivulid C. melanotaenia and provided unreported reproductive information that may aid conservation of the species. Expand
Reproduction of the threatened Annual Killifish Austrolebias nigrofasciatus (Cyprinodontiformes: Rivulidae), confined in a natural environment
The reproduction of Austrolebias nigrofasciatus, an endangered annual fish species endemic to the waters of the Sao Goncalo channel and its tributaries, demonstrates the high fecundity rate of the species even under confinement conditions. Expand
The fish fauna of the Corrientes stream basin, Patos lagoon system, state of Rio Grande do Sul, southern Brazil
The fish sampled in this study were captured in seasonal collections samplings, conducted between May 2006 and February 2007 in 15 stretches of the Corrientes stream basin, Patos lagoon system, RioExpand
Body size and population dynamics of annual fishes from temporary wetlands in Southern Brazil
The prediction that annual fish assemblages in temporary pools in Southern Brazil are structured by temporal differences in body size, specific growth rate and density is examined to provide evidence for hatching synchrony, similar specific growth rates and densities among the most abundant species and differences in bodies sizes among all species that are more evident after adulthood.

Effect of temperature on growth of the threatened annual fish Austrolebias nigrofasciatus Costa & Cheffe 2001
It appears that juveniles to be developed in captivity should be kept at 22 oC during the first six weeks of life, thus ensuring a higher growth rate until puberty, and temperature determination of phenotypic sex. Expand
Length–weight relationship of three annual fishes (Rivulidae) from temporary freshwater wetlands of southern Brazil
Three species of the family Rivulidae, Austrolebias nigrofasciatus, Aust rolebias wolterstorffi and Cynopoecilus melanotaenia are captured in temporary freshwater wetlands of southern Rio Grande do Sul, Brazil from May to December 2011. Expand
Pisces, Perciformes, Gobiidae, Evorthodus lyricus (Girard, 1858): new record from Patos-Mirim Lagoon System, state of Rio Grande do Sul, southern Brazil
The present note records for the first time the tropical gobiid fish Evorthodus lyricus from Patos- Mirim Lagoon System, state of Rio Grande do Sul, southern Brazil, the first occurrence of the species for freshwater conditions in southern Brazil. Expand
A new Dendrocephalus (Crustacea, Anostraca, Thamnocephalidae) from Rio Grande do Sul State, Brazil
This new species appears to be endemic to Rio Grande do Sul, Brazil and is most similar to Dendrocephalus goiasensis Rabet & Thiery, 1996 and could be confused with this species. Expand
