Researchers have found juvenile northern quolls have a high rate of survival when they stay in the pouch, but once they leave the pouch - with eyes still closed - baby quolls stand a low chance of survival with mum away foraging for food at night.
The typical affair used to start in the office and move to a seedy motel room, but the vast reach of the Internet has brought infidelity into many couples’ homes over the past decade.
But breeding was recorded in July on the Mitchell Plateau in Western Australia, leading researchers to conclude quolls get amorous earlier at locations closer to the coast.
First-time quoll mothers produce large litters of predominately male babies - if breeding occurs in the second year litters are smaller and predominately female.
Ms Heiniger has experienced quoll rage first hand."They are feisty. but they do have a good set of teeth on them and will attack you," Ms Heiniger said.
She presents her Ph D research into northern quolls today at the Ecological Society of Australia conference in Alice Springs.
