Abstract

AbstractWe report on the reproductive cycle and reproductive characteristics of three oviparous lizard species: Psammodromus algirus, Psammodromus hispanicus and Acanthodactylus erythrurus from a sandy coastal area in SW-Spain. Maximum testicle activity in P. algirus is research between March-May. Oviposition occurs along the activity cycle until September, clutch size average 4.8 eggs (2-10) and larger females tend to produce larger clutches. In P. hispanicus testicle reaches maximal volume during February-May. Oviposition occurs throughout April-September, and two clutches, averaging 3.6 eggs (2-5), are produced annually. In A. erythrurus mean testicle volume reaches its maximum in March, oviposition occurs in two cycles: spring and summer, clutch size averages 4.4 eggs (3-6) and increases with female snout-vent length.
