Abstract: | Since 1972 we have maintained a colony of parthenogenetic Cnemidophorus exsanguis, which has reached the seventh generation in our laboratory. This paper reports improved husbandry techniques that allow maintenance of healthy, reproducing colonies of this and additional species of Cnemidophorus. In addition, aspects of the physiology of calcium regulation and metabolic bone disease are discussed in relation to the captive rearing of lizards through many generations. |
