Cortisol-induced masculinization: does thermal stress affect gonadal fate in pejerrey, a teleost fish with temperature-dependent sex determination? [PDF]
PLoS ONE, 2009 BACKGROUND: Gonadal fate in many reptiles, fish, and amphibians is modulated by the temperature experienced during a critical period early in life (temperature-dependent sex determination; TSD).

Sex determination using mastoid process
Asian Journal of Medical Sciences, 2015 Objective: Osteometric studies using individual bones have been a topic of interest among researchers. Such researches are a tool for conducting studies related to evolution, demographic profiles and forensic sciences. Skull is important in this regard as it resists adverse environmental conditions over time.

Pattern Does Not Equal Process: Exactly When Is Sex Environmentally Determined?
The American Naturalist, 2003 Of prime importance in evolutionary biology are the description of pattern and explanations of process. Frequently, however, multiple processes can explain a given pattern. Such cases require experimental protocols or research criteria to distinguish among alternatives so pattern can be critically assigned to process.

Sex determination in the Squalius alburnoides complex: an initial characterization of sex cascade elements in the context of a hybrid polyploid genome. [PDF]
PLoS ONE, 2009 BACKGROUND:Sex determination processes vary widely among different vertebrate taxa, but no group offers as much diversity for the study of the evolution of sex determination as teleost fish. However, the knowledge about sex determination gene cascades is
