Role of temperature in sex determination in reptiles snakes in York

Journal of Animal Ecology. A slightly different example of this temperature-induced sex reversal is found in an Australian dragon lizard, which has the ZW system of sex chromosomes. There are certainly many known examples of fish and amphibians with GSD, in which both high and low incubation temperatures can cause sex reversal.

Sex determination and differentiation. Gilbert SF. In crocodilian species—the most studied of which is the American alligator— both low and high temperatures result in females and intermediate temperatures select for males. Review of Biology. Turn recording back on.

Charnier published her results in the meeting records of the local Society of Biology in West Africa, a journal with limited distribution, and her efforts were not widely recognized for several years. A widely held view is that temperature-dependent and genotypic sex determination are mutually exclusive, incompatible mechanisms—in other words, a reptile's sex is never under the influence of both sex chromosomes and environmental temperature.

Global Change Biology.

The scope of the model for other reptiles, however, requires further research. Other species show disproportionately high female production at both high and low temperatures, with intermediate temperatures causing mostly male development. Ohno, Susumu. The warming of the habitats of species exhibiting TSD are beginning to affect their behavior and may soon start affecting their physiology.
