北极狐大多是一夫一妻制,父母都照顾后代。然而,社会结构取决于捕食者和猎物的丰富程度。有时候,狐狸会形成包装,并且会混杂起来,以增加幼犬的生存并防范威胁。虽然红狐狸捕食北极狐,但这两种物种在遗传上是相容的,并且在极少数情况下已知杂交。狐狸在4月或5月繁殖,妊娠期约为52天。生活在海岸并享受稳定食物供应的蓝狐通常每年有5只幼崽。当食物稀缺时,白色的北极狐可能无法繁殖,但当猎物丰富时,白色的北极狐可能会有多达25只幼崽。这是Carnivora最大的产仔数。父母双方都帮助照顾幼崽或工具包。这些试剂盒在3至4周龄时从窝中出现,并在9周龄时断奶。当资源丰富时,较老的后代可能会留在其父母的领土内,以帮助保护它和帮助工具箱生存。北极狐只能在野外生活三到四年。在食物供应附近的窝点的狐狸往往比迁移到更大的食肉动物的动物更长寿。

澳大利亚维多利亚州论文代写:防范威胁

Arctic foxes are mostly monogamous, and parents care for future generations. However, the social structure depends on the abundance of predators and prey. Sometimes, foxes form packages and mix them together to increase the survival of puppies and prevent threats. Although the red fox preys on arctic foxes, the two species are genetically compatible and, in rare cases, hybrids are known. The fox breeds in April or May, and the gestation period is about 52 days. Blue foxes that live on the coast and enjoy a stable food supply usually have 5 cubs a year. White Arctic foxes may not be able to multiply when food is scarce, but white Arctic foxes may have as many as 25 cubs when prey is abundant. This is the largest litter size of Carnivora. Both parents help take care of the cubs or kits. These kits emerged from the litter at 3 to 4 weeks of age and were weaned at 9 weeks of age. When resources are abundant, older offspring may remain in the territory of their parents to help protect it and help the toolbox survive. Arctic foxes can only live in the wild for three to four years. Foxes in dens near food supplies tend to live longer than animals that migrate to larger carnivores.
