Description Recent findings show that global warming can cause extinction and change in the spatial distribution of various reptile species. It has been proposed, that in response, lacertiles could migrate in an altitudinal gradient, but hypoxia (oxygen shortage) is not considered as a factor that could limit migration. Here we discuss the possible adjustments in certain morpho-physiological characteristics that could allow ectotherms to migrate over an altitudinal gradient even with the negative effects of hypoxia. With this we can begin to study in depth the vulnerability of ectotherms to global warming that depends not only on their thermal biology, but also on their physiology.
Los hallazgos recientes muestran que el calentamiento global puede causar la extinción y el cambio en la distribución espacial de diversas especies de reptiles. Se ha propuesto, que en respuesta, los lacertilios podrían migrar en un gradiente altitudinal, pero no se considera a la hipóxia (escasez de oxígeno) como un factor que podría limitar la migración. Aquí discutimos las posibles adecuaciones en ciertas características morfo-fisiológicas que podrían permitir a los ectotermos migrar sobre un gradiente altitudinal aún con los efectos negativos de la hipóxia. Con esto podemos comenzar a estudiar a profundidad la vulnerabilidad de los ectotermos ante el calentamiento global que depende no solo de su biología térmica, sino también de su fisiología.
