We also thank three anonymous reviewers for their valuable feedback during the development of this manuscript. Here, we show that the proportion of nests producing both sexes is positively correlated to the width of the TRT by a correlative approach from sex ratio data collected in the literature and by simulations of TSD using a mechanistic model.

  • Sex-determining mechanisms in reptiles can be divided into two convenient classifications: genotypic (GSD) and environmental (ESD). While a number of types of GSD have been identified in a wide variety of reptilian taxa, the expression of ESD in the form of temperature-dependent sex determination (TSD) in three of the five major reptilian lineages has drawn considerable attention to this area Cited by: Apr 28,  · Environmental sex determination in reptiles.

Feb 03,  · In many reptiles, amphibians, and fishes, the environment plays a key role in determining the sexes of individuals. Temperature, in particular, appears to be a potent modulator of sex allocation in all three vertebrate classes, yet we do not yet know how temperature interacts with physiology in these systems to influence sexual cuby.info by: 3.
