N2  - Notomys alexis and Pseudomys australis have a similar pattern of reproduction but differ slightly in the timing of events. Both have a longer oestrous cycle and gestation length, a smaller litter size and a longer period of suckling than Rattus and Mus. The young of both species cling tenaciously to the teats of the mother during lactation. Delayed implantation is suspected to occur in N. alexis but not in P. australis. The pattern of reproduction is discussed in relation to the limited information on other native Muridae. It is suggested that the slower rate of reproduction could be a result of: (a) adaptation to an arid environment, or (b) an inherited pattern that has become fixed within the native Muridae.
