Original Text: Note 2

Prolonged sperm-storage is an essential component of reproductive cycle in majority of rhinolophid and vespertilionid bats undergo hibernation/winter dormancy (Racey, 1982; Crichton, 2000). These species display a clear dissociation between male and female gamete production. Spermatogenesis in these bats occurs during summer-early autumn and epididymidis are full of spermatozoa during winter until spring. Ovulation occurs on arousal from hibernation/winter dormancy (Wimsatt, 1969). In these bats, mating activity commences in the autumn, spermatozoa are then stored in the female genital tract throughout the winter hibernating period and subsequently may be used in the fertilization of ova released at ovulation after arousal in the spring (Wimsatt, 1969, Racey, 1979). The nature of the specialization that has been evolved in theses bats to permit prolonged sperm survival is still poorly understood.

These species display a clear dissociation between male and female gamete production. Spermatogenesis in these bats occurs during summer-early autumn and epididymidis are full of spermatozoa from winter until spring.

Ovulation occurs on arousal from hibernation/winter dormancy (Wimsatt, 1969). In these bats, mating activity commences in the autumn, spermatozoa are then stored in the female genital tract throughout the winter hibernating period and subsequently may be used in the fertilization of ova released at ovulation after arousal in the spring (Wimsatt, 1969, Racey, 1979).

The nature of the specialization that has evolved in these bats, to permit prolonged sperm survival, is still poorly understood.
