Reproductive biology of Pipistrellus mimus mimus (Wroughton) in the Indian desert.

(Uploaded by Plazi for the Bat Literature Project) Investigated the reproductive biology of the Pygmy Pipistrelle, Pipistrellus mimus mimus (Wroughton) in the western Rajasthan, India. Male bats remain fecund throughout the the year. The littering activity is for twelve months, January to December, when 8.3 (November) to 85.0 (August) percent females are found to be pregnant. The litter size varies from 1-3, average being 2.2. Pre embryonic losses in the population varies from 4.5 to 13.5 %, the average being 5.7. No post embryonic mortality was observed. Rainfall has indirect influence over regulation of bat populations through regulating insect diversity and abundance.
