Effects of the Incubation Environment on the Size and Incubation Time of Sceloporus Undulatus Consobrinus Hatchlings‪.‬

ABSTRACT. -- The effects of two different egg incubation environments on neonate size of Sceloporus undulatus consobrinus were studied. Egg size was not significantly different among the two treatments, but hatchlings from the 32 [degrees]C treatment (mean water potential = -400kPa), were significantly longer (Snout-Vent Length; SVL) and heavier than hatchlings from the 24 [degrees]C treatment (mean water potential = -300kPa). The incubation environment influenced hatchling size significantly in both years of the study. Implications of these findings are discussed regarding the observation of larger hatchling Sceloporus undulatus in the field late in the season. Key words: Iguanidae; Sceloporus undulatus; eggs; hatchlings; incubation environment. **********
