▪ Abstract Genetic mechanisms of sex determination are unexpectedly diverse and change
rapidly during evolution. We review the role of genetic conflict as the driving force behind …

Temperature profoundly affects the rate and trajectory of embryonic development, and
thermal extremes can be fatal. In viviparous species, maternal behaviour and physiology …

Nest site selection in reptiles can affect the fitness of the parents through the survival of their
offspring because environmental factors influence embryo survivorship, hatchling quality …

Road mortality has the potential to alter the structure of turtle populations because turtle
populations are highly sensitive to additive sources of adult mortality. To address the issue …

Nest‐site selection behavior is a maternal effect that contributes to offspring survival and
variation in offspring phenotypes that are subject to natural selection. We investigated nest …

Species with large geographical ranges provide an excellent model for studying how
different populations respond to dissimilar local conditions, particularly with respect to …

Road mortality has been implicated as a significant demographic force in turtles, particularly
for females, which are killed disproportionately on overland nesting movements. Moreover …

Theoretical models suggest that in changing environments natural selection on two traits,
maternal nesting behaviour and pivotal temperatures (those that divide the sexes) is …

It is known that turtle embryos are prone to high rates of predation; however, little is known
about microhabitat variation at the nest site and its effects on turtle embryo survival …

Most hypotheses that have been put forward in order to explain the persistence of
environmental sex determination (ESD) in reptiles assume a relatively fixed association of …
