Develo** embryos of oviparous reptiles show substantial plasticity in their responses to
environmental conditions during incubation, which can include altered sex ratios …

The turtle shell is often described as an evolutionary novelty that facilitated the radiation of
the clade Testudines. The scutes, or keratinous plates, of the turtle shell are hypothesized to …

Temperature-dependent sex determination, where egg incubation temperature irreversibly
determines offspring sex, is a common sex-determining mechanism in reptiles. Weather is …

Climate change is generating range shifts in many organisms, notably along the elevational
gradient in mountainous environments. However, moving up in elevation exposes …

Increased global temperatures have opened previously inhospitable habitats, such as at
higher elevations. However, the reduction of oxygen partial pressure with increase in …

Co** with novel environments may be facilitated by plastic physiological responses that
enable survival during environmentally sensitive life stages. We tested the capacity for …

The colonization of novel environments requires a favorable response to conditions never,
or rarely, encountered in recent evolutionary history. For example, populations colonizing …

Climate change is generating range shifts in many organisms, notably along the altitudinal
gradient. However, moving up in altitude exposes organisms to lower oxygen availability …

Ectothermic animals living at high elevation often face interacting challenges, including
temperature extremes, intense radiation, and hypoxia. While high-elevation specialists have …

The response of embryos to unpredictable hypoxia is critical for successful embryonic
development, yet there remain significant gaps in our understanding of such responses in …
