Reproduction in Seven Species of Microlophus (Squamata: Tropiduridae) from South America‪.‬

Abstract.-Information on the reproductive cycles of seven species of Microlophus (M. koepckeorum, M. occipitalis, M. peruvianus, M. stolzmanni, M. theresiae, M. thoracicus and M. tigris) from coastal northern South America gathered from a histological examination of gonadal material is presented. All species exhibited extended reproductive activity present in both austral spring-summer and autumn. Histological evidence is presented that M. peruvianus may produce multiple clutches in the same year. Comparisons are made with the reproductive cycles of other species of Microlophus. **********
