Overlap of Female Reproductive Cycles Explains Shortened Interclutch Interval in a Lizard with Invariant Clutch Size (Squamata: Gekkonidae: Paroedura picta)
Original language description
Variable clutch size is unambiguously an ancestral state in rep- tiles. Only several lizard lineages have evolved so-called invari- ant clutch size, where all females lay just one or two eggs per clutch. This mode of reproduction is characteristic for geckos. In some gecko lineages, decreased fecundity in a single clutch is compensated by conspicuous shortening of interclutch in- tervals. The proximate mechanism of high clutch frequency in these geckos is not known. Here, we document that three sub- sequently laid clutches develop simultaneously in females of the Madagascar ground gecko (Paroedura picta). The extremely short interclutch intervals in this species-even as short as a week-thus could be attributed to the overlap of female re- productive cycles. Such overlap should be associated with al- tered female hormonal cycles. Based on measurements of hor- monal levels, we suggest that cycles of estradiol and progesterone during reproductive cycles of females in P. picta are largely
