Studies on the marsupial glider, Schoinobates volans (Kerr) I. Reproduction

Abstract

Field data were obtained during the period September 1962-January 1965 from 710 greater gliders, S. volans, in a natural population. Histological changes were observed in the reproductive tracts of another 129 animals shot during this period. S. volans has a short breeding season in March, April, and May, after which involution of the reproductive organs occurs in both sexes. The species is monovular and polyoestrous. Sexual maturity is attained by both sexes in the second year, following which breeding probably occurs annually. The female reproductive system shows several primitive and anomalous features, among which is the retention of the Wolffian ducts in the adult. The histology of ovaries, uteri, and vaginae at various stages of the reproductive cycle is briefly described.
