Ecological and evolutionary theories have proposed that species traits should be important
in mediating species responses to contemporary climate change; yet, empirical evidence …

Animals at early life stages are generally more sensitive to environmental stress than adults.
This is especially true of oviparous vertebrates that develop in variable environments with …

Aim Viviparity has evolved more times in squamates than in any other vertebrate group;
therefore, squamates offer an excellent model system in which to study the patterns, drivers …

Oxygen (O 2) is essential for the survival and reproduction of most species. However, in
recent years, with global climate change and the increasing impact of human activities on …

In response to a warming climate, many montane species are shifting upslope to track the
emergence of preferred temperatures. Characterizing patterns of variation in metabolic …

Simple Summary Understanding variations in the morphology and age of animals along a
geographical gradient may aid in our comprehension of the evolution of these animals. In …

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

High altitude imposes several extreme constraints on life, such as low oxygen pressure and
high levels of ultraviolet radiation, which require specialized adaptations. Many studies have …

Montane reptiles are predicted to move to higher elevations in response to climate warming.
However, whether upwards-shifting reptiles will be physiologically constrained by hypoxia at …

The present study examined the effects of breeder age and oxygen (O₂) concentrations
during the late chorioallantoic membrane (CAM) growth stage on embryo development …
