Annual Reproductive Cycle of an Introduced Population of European Wall Lizards (Podarcis muralis) in Ohio

Abstract

The annual reproductive cycle of an introduced population of wall lizards was determined. Male lizards have a postnuptial pattern of testicular growth, with recrudescence beginning in August following a 1-2 month period of inactivity. Females exhibit ovarian growth following spring emergence and cycle until mid-July. Up to three clutches of 4-5 eggs each are oviposited annually. The timing of reproductive events is similar to that seen in lowland populations of wall lizards in Europe.
