Molecular Ecology, Volume 32, Issue 6, Page 1398-1410, March 2023., 2023 Abstract The evolution of sex chromosomes and their differentiation from autosomes is a major event during genome evolution that happened many times in several lineages. The repeated evolution and lability of sex‐determination mechanisms in fishes makes this a well‐suited system to test for general patterns in evolution.

The effect of rearing temperature in larval development of pejerrey, Odontesthes bonariensis- Morphological indicators of development [PDF]
, 2011 It is well known that in pejerrey water temperature not only affects growth rates but also directs the sexual differentiation process. This fact rise the question of how different the development of pejerrey larvae of the same age is when reared at ...

Gayana (Concepción), 2011 Se prueba el potencial de amplificacion de 8 microsatelites descritos inicialmente para Odontesthes perugiae y O. argentinensis en 3 especies de Odontesthes y 4 especies de Basilichthys. La mayoria de los partidores microsatelites amplificaron correctamente y presentan polimorfismo por lo que seran de utilidad en planes de conservacion genetica de ...

Análise comparativa entre técnicas morfométricas aplicadas a Odontesthes bonariensis (Valenciennes) e Odontesthes humensis De Buen (Osteichthyes, Atherinopsidae) [PDF]
Revista Brasileira de Zoologia, 2002 The objective of this study was to compare two different morphometric methodologies - traditional measurements and truss networks - based on two species of silversides, Odontesthes bonariensis (Valenciennes, 1835) and O. humensis De Buen, 1953, to determine which of the methods results in more reliable distinction between groups.

Survival of embryos of pejerrey Odontesthes bonariensis and Odontesthes humensis at different concentration of salinity [PDF]
Biotemas, 2009 Embryos of Odontesthes bonariensis and Odontesthes humensis were submitted to saline concentrations of 0, 5, 10, 20 and 30g.L-1. The control of mortality was made daily between the 8th and 12th days of incubation, at the which time the embryos had ...

Use of otolith strontium:calcium ratio as indicator of seasonal displacements of the silverside (Odontesthes bonariensis) in a freshwater-marine environment [PDF]
, 2013 Strontium:calcium ratios were measured in sagittal otoliths of silverside (Odontesthes bonariensis) from a freshwater-marine environment (Paraná River Delta and River de la Plata River, South America) in order to understand its seasonal movements ...

Frontiers in Genetics, 2018 Some mammalian reference genes, which are widely used to normalize the qRT-PCR, could not be used for this purpose due to its high expression variation. The normalization with false reference genes leads to misinterpretation of results.
