Whether species that have persisted throughout historic climatic upheavals will survive
contemporary climate change will depend on their ecological and physiological traits, their …

Lizards represent unique model organisms in the study of sex determination and sex
chromosome evolution. Among tetrapods, they are characterized by an unparalleled …

Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis
and the fusion of two gametes of different sexes or mating types. Sex-determination …

Sex determination is a fundamental biological process, yet its mechanisms are remarkably
diverse,. In vertebrates, sex can be determined by inherited genetic factors or by the …

Amniote vertebrates, the group consisting of mammals and reptiles including birds, possess
various mechanisms of sex determination. Under environmental sex determination (ESD) …

Sex reversal is the process by which an individual develops a phenotypic sex that is
discordant with its chromosomal or genotypic sex. It occurs in many lineages of ectothermic …

In this review, we consider the insight that has been gained through theoretical examination
of environmental sex determination (ESD) and thermolability–how theory has progressed …

Haplodiploid species display extraordinary sex ratios. However, a differential investment in
male and female offspring might also be achieved by a differential provisioning of eggs, as …

Variable environmental conditions can alter the phenotype of offspring, particularly in
ectothermic species such as reptiles. Despite this, the majority of studies on development in …

Understanding gonadal development in lampreys is complicated by their complex life cycle,
the long period during which their gonads remain histologically undifferentiated, and their …
