Abstract:

In 1968 and 1973 in southwestern Idaho, 275 Uta stansburiana were collected. Uta occupies low hills with rocky outcrops and flat sparse vegetation consisting of the following shrubs: Artemisia tridentata, Grayia spinosa, Atriplex confertifolia, Chrysothamnus nauseosus, and Atriplex canescens. Emergence from hibernation occurs from mid-March to early April and the first yolked follicles appear in early April, with oviducal eggs present in late April. Testicular cycle begins with the emergence of males, and spermatozoa are produced from April through July. Uta reaches sexual maturity in one year at a SVL of 40.0 mm in males and 43 mm in females. Overall clutch size is 3.75 eggs (1–2 clutches per year). Fat body size at emergence is not known, but what is present shows a decline in males and females until July, when a substantial increase occurs. Sex ratios are about 1:1 in all months and seasons except June 1968, according to chi-square analysis.
