Ultramorphological changes in gill rakers of Astyanax altiparanae (Characidae) kept in contaminated environments [PDF]
Fish Physiology and Biochemistry, 2017 Most water bodies in Brazil, and in the world, are contaminated by some types of pollutants, ranging from sewage to metal/chemicals, carcinogenic products, and biodegradable detergents. Despite the extensive knowledge on their effects on fish biology and especially on gill morphology, research that concerns their impacts on gill rakers and implications

Journal of Applied Ichthyology, 2021 Gynogenesis is a chromosomal manipulation technique where an offspring is generated exclusively from maternal inheritance. In the yellowtail tetra (Astyanax altiparanae) almost all gynogenetic fish were females, suggesting a genetic sex determination system of XX/XY. However, due to environmental (e.g.

Molecular study of Astyanax altiparanae (Osteichthyes, Characidae) as a probable species complex
Genetics and Molecular Research, 2014 Astyanax altiparanae, belonging to the bimaculatus group, which includes species with similar colors and morphology, occurs in the upper Paraná River basin. As the use of mitochondrial DNA has made great strides in the diagnosis of species, in previous researches, two strains were detected in A.
