美洲旱獭种

与人类的关系

美洲旱獭的巢穴中常有共生的红狐、臭鼬或棉尾兔存在。红狐、臭鼬经常捕食蚂蚱、田鼠等危害农作物的生物，加上美洲旱獭挖的洞疏松了土壤，它被农民们看作是一种益兽。不过有时它也会被当做食物、娱乐用的猎物、或者是医学实验动物。

美洲旱獭可以人工饲养，但因为其天性好斗而难以驯化。

The groundhog (Marmota monax), also known as the woodchuck, is a rodent of the family Sciuridae, belonging to the group of large ground squirrels known as marmots.

A lowland creature of North America, it is found through much of the Eastern United States, across Canada and into Alaska.

It was given its scientific name as Mus monax by Carl Linnaeus in 1758, based on a description of the animal by George Edwards, published in 1743.

The groundhog, being a lowland animal, is exceptional among marmots. Other marmots, such as the yellow-bellied and hoary marmots, live in rocky and mountainous areas. Groundhogs are considered one of the most solitary of marmot species. They live in aggregations, and their social organization and long-term pair bonds varies across populations. The groundhog's male and female interactions are usually limited to the mating season and copulation. However, certain populations of groundhogs have been observed to form long-term adult male-female association throughout the year, and often from year to year.

The groundhog is an important contributor to the maintenance of healthy soil in woodlands and plains; as such, the species is considered a crucial habitat engineer. The groundhog is an extremely intelligent animal, forming complex social networks and kinship with its young; it is capable of understanding social behavior, communicating threats through whistling, and working cooperatively to accomplish tasks such as burrowing.
