女性在分娩后可以进入体温，因此当一个乔伊仍然在她的小袋中哺乳时，她们可能会怀孕。正在发育的婴儿将进入休眠状态，与他们的兄弟姐妹留下母亲的小袋一致。当年长的兄弟姐妹离开小袋时，母亲的身体会向正在发育的婴儿发出激素信号，以便它恢复发育。如果母亲怀孕并且年长的乔伊在她的小袋中死亡，则会发生类似的过程。袋鼠被国际自然保护联盟（IUCN）指定为最不关心的问题。他们的人口非常丰富，据估计，澳大利亚的袋鼠数量多于人口。估计范围从4千万到5千万只袋鼠中继续增加。人类是袋鼠的主要威胁，因为它们的肉和皮都被捕杀。由于土地清理发展，人类也可能导致袋鼠栖息地的丧失。捕食者威胁包括野狗和狐狸。袋鼠使用他们的牙齿，爪子和强壮的后腿作为对抗这些捕食者的防御机制。
澳大利亚图文巴Essay代写：土地清理发展
Women can enter their body temperature after giving birth, so when a Joey is still breastfeeding in her pouch, they may become pregnant. Growing babies will go to sleep, in line with their siblings leaving their mother’s pouch. When older siblings leave the pouch, the mother’s body sends a hormonal signal to the developing baby so that it can resume development. A similar process occurs if the mother is pregnant and the older Joey dies in her pouch. Kangaroos have been designated by the International Union for Conservation of Nature (IUCN) as the least concerned issue. Their population is very rich and it is estimated that there are more kangaroos in Australia than in the population. The estimated range continues to increase from 40 million to 50 million kangaroos. Humans are the main threat to kangaroos because their meat and skin are hunted. Humans may also cause loss of kangaroo habitat due to land development. Predator threats include wild dogs and foxes. Kangaroos use their teeth, claws and strong hind legs as a defense against these predators.
