Distribution modeling of Psellogrammus kennedyi (Eigenmann, 1903) and new records in the Lower Paranapanema River, Brazil [PDF]

Check List, 2021
Understanding the potential distribution of non-native species can be an important tool in preventing biological invasions. We recorded for the first time Psellogrammus kennedyi, a small non-native characiform, in the Lower Paranapanema River, Brazil ...

MICOBACTERIOSE EM PEIXES

Boletim do Instituto de Pesca, 2018
A micobacteriose é uma doença que pode afetar várias espécies de peixes, incluindo-se as espécies utilizadas em criações comerciais. É uma doença crônica, granulomatosa, denominada tuberculose ou, simplesmente, micobacteriose de peixes. Nos últimos anos,

Lipídios em peixes

Vetor, 2007
A composição química dos peixes, em particular a fração lipidica, está intimamente relacionada com o habitat e o tipo de alimentação dos mesmos. Esta difere dos outros óleos e gorduras, que ocorrem naturalmente, por conter grandes quantidades de ácidos ...

Long-term monitoring reveals a consistent female-biased sex ratio in Pimelodus maculatus from the Upper Uruguay River Basin

Boletim do Instituto de Pesca, 2023
Sex ratio is a crucial demographic parameter for the viability of natural populations, and it is commonly balanced in Neotropical freshwater fish species.

The Genetic Differentiation of Pyrrhulina (Teleostei, Characiformes) Species is Likely Influenced by Both Geographical Distribution and Chromosomal Rearrangements

Frontiers in Genetics, 2022
Allopatry is generally considered to be one of the main contributors to the remarkable Neotropical biodiversity. However, the role of chromosomal rearrangements including neo-sex chromosomes for genetic diversity is still poorly investigated and ...

Homeology of sex chromosomes in Amazonian Harttia armored catfishes supports the X-fission hypothesis for the X1X2Y sex chromosome system origin

Scientific Reports, 2023
The Neotropical monophyletic catfish genus Harttia represents an excellent model to study karyotype and sex chromosome evolution in teleosts. Its species split into three phylogenetic clades distributed along the Brazilian territory and they differ ...

Microsatellite loci in the tiger shark and cross-species amplification using pyrosequencing technology [PDF]

PeerJ, 2016
The tiger shark (Galeocerdo cuvier) has a global distribution in tropical and warm temperate seas, and it is caught in numerous fisheries worldwide, mainly as bycatch.

Integrating Cytogenetics and Population Genomics: Allopatry and Neo-Sex Chromosomes May Have Shaped the Genetic Divergence in the Erythrinus erythrinus Species Complex (Teleostei, Characiformes)

Biology, 2022
Diversity found in Neotropical freshwater fish is remarkable. It can even hinder a proper delimitation of many species, with the wolf fish Erythrinus erythrinus (Teleostei, Characiformes) being a notable example.
