Recently, the importance of the female to population dynamics—especially her non‐genetic
contribution to offspring fitness or maternal effect—has received much attention in studies of …

Environmental sex determination has been documented in a variety of organisms for many
decades and the adaptive significance of this unusual sex‐determining mechanism has …

Sex determination in animals is amazingly plastic. Vertebrates display contrasting strategies
ranging from complete genetic control of sex (genotypic sex determination) to …

Environmental sex determination (ESD) occurs in divergent, phylogenetically unrelated taxa,
and in some species, co-occurs with genetic sex determination (GSD) mechanisms …

Recent decades have witnessed an explosion of theoretical and empirical studies of sex
allocation, transforming how we understand the allocation of resources to male and female …

Understanding the mechanisms that determine an individual's sex remains a primary
challenge for evolutionary biology. Chromosome-based systems (genotypic sex …

Squamate reptiles possess two general modes of sex determination:(1) genotypic sex
determination (GSD), where the sex of an individual is determined by sex chromosomes, ie …

To understand how selection shapes life-history traits, we need information on the manner in
which offspring phenotypes influence fitness. Life-history allocation models typically assume …

Background Vertebrates exhibit diverse sex determination systems and reptiles stand out by
having highly variable sex determinations that include temperature-dependent and …

Reptiles are critically affected by temperature throughout their lifespan, but especially so
during early development. Temperature-induced changes in phenotype are a specific …
