竹鼠 ,四种亚洲种类的穴居,缓慢移动,夜间啮齿动物 。 竹鼠具有健壮的圆柱体,小耳朵和眼睛,以及短而粗壮的腿。 三种Rhizomys长23至50厘米(9.1至19.7英寸),短而秃头或稀疏的尾巴(5至20厘米)。 上部的毛皮柔软,致密或粗糙,颜色浅,灰色至棕灰色,下面较浅。 该 较小的竹鼠 ( Cannomys属 )较小 - 15至27厘米长,不包括6至8厘米的尾巴。 它长而浓密的毛皮从栗色棕色到明亮的浅灰色。

  • Bamboo rat, any of four Asiatic species of burrowing, slow-moving, nocturnal rodents. Bamboo rats have a robust, cylindrical body, small ears and eyes, and short, stout legs. The three species of Rhizomys are 23 to 50 cm (9.1 to 19.7 inches) long with a short and bald or sparsely haired tail (5 to 20 cm). Fur on the upperparts is soft and dense or harsh and scanty, coloured slate gray to brownish gray with a paler underside. The lesser bamboo rat (genus Cannomys) is smaller—15 to 27 cm long, excluding the 6- to 8-cm tail. Its long, dense fur ranges from chestnut brown to a bright pale gray.

Rhizomys属植物存在于从印度支那到马来半岛和苏门答腊岛的竹子覆盖的山丘和山脉中,老鼠在那里饲养三到五只幼仔。 另一方面,较小的竹鼠栖息在从尼泊尔东南部通过中国南部和缅甸(缅甸)到越南西北部和泰国的高地; 它的窝产仔数是一到两个。 所有竹鼠都是这些国家土着人的食物来源。

  • The genus Rhizomys is found in bamboo-covered hills and mountains from Indochina to the Malay Peninsula and Sumatra, where the rats bear litters of three to five young. The lesser bamboo rat, on the other hand, inhabits uplands from southeastern Nepal through southern China and Myanmar (Burma) to northwestern Vietnam and Thailand; its litter size is one to two. All bamboo rats are a food source for the native peoples of these countries.

竹老鼠用他们的门牙挖掘,用头部和爪子去除松散的土壤。 Rhizomys物种构成广泛 密集竹林根部的洞穴系统,主要以竹根为食。 到了晚上,他们在地上觅食水果,种子和巢穴材料,甚至攀爬竹子并切割它们带到洞穴的部分,然后再吃。 据报道,他们还冒险进入种植园,以甘蔗和木薯的根为食。 较小的竹鼠在山地草甸,森林,甚至花园的岩石地下挖掘深隧道; 它的饮食包括各种各样的植物材料。 已在茶园中发现,但其造成的损害程度尚不清楚。

  • Bamboo rats dig with their incisor teeth, using the head and claws to remove loosened soil. Rhizomys species construct extensive burrow systems among roots of dense bamboo stands, where they feed primarily on bamboo roots. At night they forage above ground for fruit, seeds, and nest materials, even climbing the bamboo and cutting sections that they carry to their burrows and eat later. They have also been reported to venture onto plantations to feed on roots of sugarcane and cassava. The lesser bamboo rat digs deep tunnels in the rocky ground of mountain meadows, forests, and even gardens; its diet consists of a wide variety of plant material. It has been found on tea plantations, but the extent of the damage it causes is unknown.

除了单一种类的小竹鼠( C. badius )外,还有三种Rhizomys竹鼠 中国竹鼠( R. sinensis ), 古老的竹鼠( R. pruinosus ),和 大竹鼠( R. sumatrensis )。 所有的竹鼠都属于Rhyzomyinae亚科,其中包括最亲密的亲戚 非洲鼹鼠 ( Tachyoryctes属)。 亚科Rhyzomyinae属于啮齿目( Rodentia )的鼠科 (鼠科和小鼠)。 今天的Rhizomys物种的谱系可以追溯到巴基斯坦, 印度和中国发现的化石所代表的灭绝属,这些化石可追溯到10,000,000到50万年前( 中新世晚期到更新世时期 )。

  • In addition to the single species of lesser bamboo rat (C. badius), the three Rhizomys bamboo rats are the Chinese bamboo rat (R. sinensis), the hoary bamboo rat (R. pruinosus), and the large bamboo rat (R. sumatrensis). All bamboo rats belong to the subfamily Rhyzomyinae, which includes their closest living relatives, the African mole rats (genus Tachyoryctes). Subfamily Rhyzomyinae is classified within the family Muridae (rats and mice) of the order Rodentia. The lineage of today’s Rhizomys species can be traced to extinct genera represented by fossils found in Pakistan, India, and China dating from 10,000,000 to 500,000 years ago (late Miocene to Pleistocene Epoch).
