The Tree lizard (Urosaurus ornatus) is a species of lizard native to the southwestern United States, and northern Mexico. The species has been used to research the physiological changes in the body during the fight-or-flight response as related to stress and aggressive competition [PMID 9145930]. Also, it's life history and costs of reproduction have been documented in field populations in New Mexico. (Landwer, 1994)Oecologia

[edit] Reproduction
A group of one male and one or more females typically inhabit an area that contains one or more large tree or shrub. The male copulates with each female and the female deposits eggs aproximately two weeks after mating. In many parts of the Tree Lizard's range females may lay more than one clutch of eggs a year.
