Geographic Variation In The Lower Temperature Tolerance In The Invasive Brown Anole, Anolis Sagrei And The Native Green Anole, Anolis Carolinensis (Sauria: Polychrotidae), Laura Carolina Maria Rubio

Masters Theses

Invasive species are considered to be the second greatest threat to native biodiversity and several factors have been identified as contributing to the success of introduced species, including their initial genetic variation and the ability of populations to adapt to a new environment. Temperature has a significant impact on reptilian ecology and distribution since they ordinarily rely on external heat sources for the maintenance of body temperatures suitable for normal activity. Body temperature affects performance in these organisms given its importance for all aspects of behavior, locomotion, courtship and rates of feeding and growth. Critical thermal tolerances can, therefore, give …
