Photoperiod and temperature as inducers of gamogenesis in a dicyclic population of Scapholeberis armata Herrick (Crustacea : Cladocera : Daphniidae)

The induction of gamogenesis in a dicyclic population of Scapholeberis armata from a small pond at 40 degree N in Pennsylvania, USA, was studied. Animals were collected at the time of gamogenesis. Test animals were observed bidaily or daily for up to 37 days. Occurrence of molts and of parthenogenet...
