There is little information on the reproduction in Pseudochirulus cinereus. Inferences are made according to the reproduction of similar ringtail possums found in similar areas (Springer and Kirsch, 1989). Daintree river ringtail possums probably spend most of their lives alone, only meeting up with members of the opposite sex prior to breeding (Queensland Department of Environment and Heritage, 1992). They are typically polygynous animals but may shift between monogamy and polygyny depending on resource availability ("Ringtail and greater gliding possums", 2004).
Mating System: monogamous ; polygynous
Pseudochirulus cinereus individuals may start reproducing between 18 months and 2 years old (Springer and Kirsch, 1989). Daintree River ringtail possums may breed throughout the year, but mating peaks in April and May. The average litter size is 2 young and breeding occurs once annually. Young may spend 4 to 5 months in their mother's pouch after which they will be carried on her back (Nowak, 1999). Weaning in similar species occurs at 150 to 160 days, and young ringtail possums may become independent at 10 months ("Ringtail and greater gliding possums", 2004). Generation times for pseudocheirids is generally 2 to 4 years. Researchers believe that size may be an important factor in determining the duration of generation time. Because Pseudochirulus cinereus is smaller in size compared to other ringtail possums, they may have a shorter generation time (Springer and Kirsch, 1989).
Breeding interval: Breeding occurs throughout the year but peaks in April and May.
Breeding season: Breeding occurs from April through May.
Range number of offspring: 2 (high) .
Range weaning age: 150 to 160 days.
Range time to independence: 10 (high) months.
Range age at sexual or reproductive maturity (female): 1.5 to 2 years.
Range age at sexual or reproductive maturity (male): 1.5 to 2 years.
Key Reproductive Features: iteroparous ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous
Information regarding much of the reproduction of Pseudochirulus cinereus is unknown (Springer and Kirsch, 1989). Females carry the young in their pouches or on their backs (Nowak, 1999), and older young are sometimes left alone on a branch until their mother returns (Queensland Department of Environment and Heritage, 1992). Due to the solitary lifestyle of Daintree River ringtail possumss (Andromeda Oxford Ltd., 2001), males probably do not contribute to providing for or protecting their young.
Parental Investment: altricial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female); pre-independence (Provisioning: Female, Protecting: Female)
