Also known as the marmot genus, marmots, groundhogs, groundhog

Marmots are large ground squirrels in the genus Marmota, with 15 species living in Asia, Europe, and North America. These herbivores are active during the summer, when they can often be found in groups, but are not seen during the winter, when they hibernate underground. They are the heaviest and largest members of the squirrel family.

OverviewAI-generated

Marmota is a genus of mammals within the family Sciuridae, commonly referred to as marmots. It belongs to the order Rodentia, class Mammalia, and phylum Chordata. The genus is part of the ground squirrels group and was described by Blumenbach in 1779. Its temporal range extends back to the Miocene epoch.

The species are diurnal animals. While the genus includes various species, one is commonly known as the groundhog. Records indicate that Marmota is not extinct. The taxon has been documented in the United States, with occurrence records held by institutions such as CM.

旱獺屬是一種松鼠科的屬，常稱為土撥鼠屬，包含15個物種，常見物種為旱獺。部份物種居於山區，如歐洲的阿爾卑斯山、北美洲的黑山、印度的拉達克等。牠們正常會自挖洞作為藏生居所，牠們在冬天會冬眠。草原犬鼠是另一種同被稱為土撥鼠但不納入本屬的動物，不過兩種動物有很多相似之處。 旱獺屬是草食動物，主要食物為草、漿果、地衣、苔蘚、根和花。 亞屬與種 以下旱獺屬種列表參考自 Thorington 與 Hoffman[1]，加上之後發現的 M. kastschenkoi[2]。兩位科學家將旱獺屬分做兩個亞屬。 旱獺屬 Marmota 亞屬 阿拉斯加旱獺（英语：Alaska marmot） M. broweri：分布於阿拉斯加 阿爾卑斯山旱獺（英语：Alpine marmot） M. marmota：分布於歐洲阿爾卑斯山、義大利亞平寧山脈北部、喀爾巴阡山脈、亞平寧山脈，並重新引進至庇里牛斯山 黑頭旱獺（英语：Black-capped marmot） M. camtschatica：分布於東西伯利亞 旱獺 M. bobak：分布於中歐至中亞地區 Forest-steppe marmot（英语：Forest-steppe marmot） M. kastschenkoi：分布於南俄[2] 灰旱獺（英语：Gray marmot） M. baibacina：分布於西伯利亞 美洲旱獺 M. monax：又稱為美洲土撥鼠，分布於北美洲 喜馬拉雅旱獺 M. himalayana：分布於喜馬拉雅山脈 長尾旱獺：分布於中亞 明氏旱獺（英语：Menzbier's marmot） M. menzbieri：分布於中亞 蒙古旱獺（英语：Tarbagan marmot） M. sibirica：分布於蒙古與西伯利亞 Petromarmota 亞屬 蒙塔古島褐旱獺（英语：Hoary marmot） M. caligata：發現於加拿大與阿拉斯加 奧林匹亞旱獺（英语：Olympic marmot） M. olympus：美國華盛頓州奧林匹克半島（英语：Olympic Peninsula）特有種 溫哥華島旱獺（英语：Vancouver Island marmot） M. vancouverensis：加拿大不列顛哥倫比亞省溫哥華島特有種 黃腹土撥鼠 M. flaviventris：分布於西南加拿大與美國西部 另外，從化石紀錄中共辨識出 4 種已滅絕種： †Marmota arizonae：發現於美國亞利桑那州[3] †Marmota minor：發現於美國內華達州[4] †Marmota robusta：發現於中國 †Marmota vetus：發現於美國內布拉斯加州[5] 参考文献 ^ Thorington, R.

==Description== thumb|North American marmot, Montreal, Canada Marmots are large rodents with characteristically short but robust legs, enlarged claws that are well adapted to digging, stout bodies, and large heads and incisors to quickly process a variety of vegetation. While most species are various forms of earthen-hued brown, marmots vary in fur coloration based roughly on their surroundings. Species found in more open habitats are more likely to be paler color, while those found in well-forested regions tend to be darker. Total length varies typically from about and body mass averages about in spring in the smaller species and in autumn, at times exceeding , in the larger species. The largest and smallest species are not clearly known. In North America, on the basis of mean linear dimensions and body masses through the year, the smallest species appears to be the Alaska marmot and the largest is the Olympic marmot. Some species, such as the Himalayan marmot and Tarbagan marmot in Asia, appear to attain roughly similar body masses to the Olympic marmot, but are not known to reach as high a total length as the Olympic species. Using the traditional definition of hibernation, the largest marmots are considered the largest "true hibernators", since larger "hibernators" such as bears do not have the same physiological characteristics as obligate hibernating animals such as assorted rodents, bats and insectivores).
