Global Warming and the Physiology of Ectothermic Animals: The Case of Three Mexican Lizards
Journal Title: International Journal of Zoology and Animal Biology - Year 2019, Vol 2, Issue 6
Abstract
Global warming has a direct impact on the geographic distribution and abundance of reptiles, and it can even lead to their extinction. Theoretical models project that many lizards could migrate along an altitudinal gradient, however, this prediction does not take into account lack of oxygen or hypoxia as a constraint factor for migration. We discuss possible morpho physiological traits that could affect whether ectotherms can migrate from lower to higher altitudes, despite the potential negative effects of hypoxia. It is fundamental that climate change research considers the vulnerability of ectotherms facing global warming, not only in terms of their thermal biology, but also considering their physiology.
