Lack of influence of photoperiod on the brood interval of the guppy (Poecilia reticulata )

Lack of influence of photoperiod on the brood interval of the guppy (Poecilia reticulata )

Domesticated and feral guppies (P. reticulata ) were isolated under a variety of photoperiods (3L21D, 8L16D, 12L12D, 16L8D and 24L0D), and the time interval between two successive parturitions recorded. Contrary to earlier reports, there was no evidence for an inverse relationship between photoperio...
