Hormone Research. Permissions Icon Permissions. Adaptation, extinction and global change. Physiological plasticity e. This phase is followed by the degeneration of the male reproductive system and a period of lability. Similarly, the presence of large numbers of males will cause some of the males to become females.

No sex ratio data are available for and summer floods eliminated recruitment in those years.

Environmental sex determination: interaction of temperature and genotype in a fish. After Coe To determine the extent to which any of these traits could contribute to the microevolution of TSD under anthropogenic climate change, at a minimum we must quantify the heritability of these traits in wild populations.

The warmth early in the season ensures female-biased broods that then have more time to grow and reach maturity and possibly reproduce before they experience their first winter, thereby increasing fitness of the individual.

It is not known whether the temperature sensitivity resides in the aromatase gene or protein itself or in other proteins that regulate it. External link. Temperature-dependent aromatase activity is also seen in diamondback terrapins, and its inhibition masculinizes their gonads Jeyasuria et al.

Jun 01,  · In contrast, temperature-dependent sex determination (TSD), where sex is determined by thermal conditions experienced in the lability period during gonadal development, is present in most reptile lineages (many turtles, all sphenodontians, a few lizards and all crocodilians studied) (Bull, ; Pieau, ). Thus, TSD is a case of phenotypic Cited by: 2.
