The cellular basis of compensatory muscle growth in the teleostOdontesthes bonariensis

Journal of Experimental Biology, 2022
ABSTRACTThis study evaluates white muscle growth and in vivo cell proliferation during a fasting and refeeding trial, using pejerrey (Odontesthes bonariensis) as animal model, in order to better understand the cellular basis governing catch-up growth. Experiments consisted of two groups of fish, a control group continuously fed ad libitum, and a group ...

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.

Ecotoxicological tests with cadmium and chromium using postlarvae of silverside Odontesthes (Austromenidia) regia regia Hildebrand

Revista Peruana de Biología, 2014
In the present paper, the mean effective concentrations (EC50%) of cadmium (Cd+2) and chromium (Cr+6) using postlarvae of the silverside fish Odontesthes (Austromenidia) regia regia were determined. The postlarvae were exposed to different concentrations

Transgenerational Heat Exposure Triggers Unexpected Compensatory Sex Ratio Responses in a Temperature‐Sensitive Fish Under Climate Warming

Global Change Biology, Volume 32, Issue 3, March 2026.
Rising temperatures can unbalance the number of males and females in species whose sex is influenced by the environment. In a decade‐long experiment with European sea bass, we found that heat during development produces more males, but the thermal history of parents—especially fathers—can unexpectedly push offspring sex ratios back in the opposite ...
