The mating behaviour of the dibbler, Parantechinus apicalis, in captivity

Abstract

A study of the mating behaviour of the dibbler, Parantechinus apicalis, was conducted at a captive-breeding colony at Perth Zoo. In total, 21 pairs of P. apicalis were observed. The oestrous cycles of the females were monitored, and the males and females were paired when the females were approaching oestrus. Direct observations were made of the pairs over a 2-h period 3–4 times a week for the duration of the breeding season (mid February to April). It was found that the mating behaviour of P. apicalis was similar to that of other dasyurids; in particular, sniffing, vocalisations, chasing and attempted mounting tended to increase in the days leading up to mating. No significant difference was found between successful pairs (i.e. those that did mate) and unsuccessful pairs (i.e. those that did not) in the number of interactions and the average distance between the pair.
