雄性北方袋鼬在繁殖季節會長途跋涉並花很長時間尋找配偶,期間只花約 8% 的時間休息。牠們因花更少時間梳理毛髮變得容易生病,也更容易被掠食者捕食。研究認為這可能是造成北方袋鼬每年大量死亡的原因。
During breeding seasons, male northern quolls travel long distance and spend long period of time to search for mates, and rest only 8%of the time during this period. they spend less time to groom and become easier to get sick and being caught by predators as well. This may be the cause of the annual mass die-off of male northern quolls.
