Taiwanese brown-toothed shrew
Episoriculus fumidus is a shrew of the genus Episoriculus. She lives endemic to the island of Taiwan.
Features
With a head-body length of 5.3 to 7.1 centimeters, the type is one of the medium-sized shrew species. The tail reaches a length of 3.7 to 5.2 centimeters and the hind of 1.1 to 1.5 centimeters. The dorsal coloration is brown with a sharp separation of the gray-colored belly. The tail is compared to other species with a length of less than half of the head -body length is comparatively short. He is on the upper side dark and stained hand brighter.
The skull has a maximum length of 18 to 19 mm. The teeth are typicaly designed, most notably the shape of the fourth premolar and molars of the two is not as strong concave as in the related species. The genome consists of a diploid chromosome complement of 2n = 64 chromosomes.
Dissemination
Episoriculus fumidus is endemic spread on the island of Taiwan, where the species is detected in the high altitudes of the Alishan National Scenic Area to heights of 2438 meters. Both in Alishan as well as in Tsuifeng (2300 meters) she lives sympatric with Chodsigoa sodalis.
Way of life
The preferred habitat of Episoriculus fumidus located on lush forest soils in both deciduous and coniferous forests and thickets of the subalpine high altitudes in the high mountains of Taiwan. The animals are both active during the day as at night.
The breeding season falls in the dry season to Taiwan by May to June. The females give birth to a litter 2-4 pups, with an average of 3.4. It is not known whether there is another breeding season and other throws.
System
Episoriculus fumidus is classified as a separate species within the genus Episoriculus, which consists of four types. The first scientific description comes from Oldfield Thomas in 1913. E. fumidus was originally considered a subspecies of Episoriculus caudate, which is found on the Asian mainland, but later described as an independent species. It contained Chodsigoa sodalis as a subspecies that is now assigned as a distinct species of the genus Chodsigoa.
Within the species, no further addition to the nominate subspecies are distinguished.
Threat and protection
The type is determined by the International Union for Conservation of Nature and Natural Resources ( IUCN) adopted due to high inventory levels and the occurrence in at least one protected area, the Yushan National Park, despite the relatively small distribution area on the island of Taiwan as not at risk ( " least concern " ) classified. Threats to the species are not known and a significant decline in the populations will not be accepted.
