Biparental care in Djungurian but not Siberian dwarf hamsters (Phodopus)

Article Abstract:

The parental behavior of male Djungurian (Phodopus campbelli) and Siberian (Phodopus sungorus) dwarf hamsters was investigated. The results showed that P. campbelli pups were rarely left alone when housed with a second adult. On the other hand, P. sungorus males were rarely alone with their pups and they had little impact on the parental care received by the same. There are indications, however, that biparental care would be facultative and adaptive under certain environmental conditions.

Scent counter marks: selective memory for the top scent by golden hamsters

Article Abstract:

Hamsters remember only one of the two scents, the top revealing scent, indicating that hamsters have unsuspected mechanism for knowing which individual scent is on top. The technique of remembering the top or more current individual scent may be an adaptive way of dealing with a complex array of social scents. The study on male hamster, Mesocricetus auratus shows that it does not remember the bottom and/or older scent.

Paternal behavior in biparental hamsters, Phodopus campbelli, does not require contact with the pregnant female

Article Abstract:

Research designed to test whether cues from the pregnant female are significant for the expression of midwife and paternal behaviour in Djungarian hamsters is presented. This work disproved the view that male Djungarian hamsters need stimuli from the pregnant female to prompt paternal behaviour during the birth of the litter and to respond to the pups following the birth.
