Closed circles represent males, open circles females. Comparison of the Two Altitudes There are no significant differences in growth rates of Uzards of comparable age-sex categories at high and low altitudes (Table 4). Heliothemiic behaviorenablesA. tiihcirulatcno grow atthe same rate at different altitudes. However, the elevation of the regression lines is significantly higher for juveniles and subadults at low altitude. Lizards living at low altitude have a longer growing season and thus are able to reach sexual maturity approxi- mately a year earlier than those living at 2165 m. Similarly, high altitude populations of Lacerta rivipara in France take 2 years to mature compared to only 1 year for low altitude populations (Huelin, 1985). Ballinger (1979) found Sceloporus janvvi to mature in 5 months at 1675 m and in 15 months at 2542 m. In his study comparing Colorado and Texas populations of Uta stansbwiana. Tinkle (1967) found that the former grew at the same rate as the latter but took longer to reach sexual matu- rity because they hatched later in the summer and had a shorter growing Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Waltner, Robert C.
