Body size and microhabitat affect winter survival of hatchling Psammodromus algirus lizards

To examine factors related to overwinter survival of Psammodromus algirus h atchlings, we performed a capture-mark-recapture study of a cohort of hatch lings. In this work, we examine the effects of body size, vegetation struct ure of the home range, tail condition, sex, and estimated hatching date on hatchling survivorship to the next spring. Results of a logistic regression analysis showed that survival was associated with larger body size (SVL), higher cover, and earlier hatching date. Tail condition and sex were not as sociated with overwinter survivorship.
