Mogera kobeae Thomas, 1905 |
The Japanese mole (Mogera wogura), also known as Temminck's mole, is a species of mole endemic to Japan. A solitary and diurnal species, it can live for up to 3.5 years in the wild. Their sizes vary depending on the temperature and the hardness of the soil they reside in.
The Kobe mole (M. kobeae) was formerly described as a distinct species, but is now known to be conspecific with M. wogura.
This species has shown signs of genetic drift through either paripatric or peripatric speciation. This conclusion has been reached due to the dental anomalies found within the Japanese Mole populations, depending on the region where the Japanese mole is found.
M. wogura is believed to have derived from the arrival of its ancestor to Japan around 0.1 to 0.01 MYA. This was around the last recorded glacial period.
Locomotion
The Japanese mole (Mogera wogura) uses two methods of locomotion: crawling and burrowing, which provide an insight into its highly evolved mechanism of strong neural control. The Japanese mole's neural connections in its thoracic and lumbar vertebrate have an extremely strong connection with its fore and hindlimbs, which aid it in locomotion. They use these skills to remove piles of loose dirt through stroke-like movements compared to that of swimming.
Ecology
Based on observations of previous specimens of the litter size of M. tokudae (including M. etigo), M. imaizumii (Abe 1968), M. wogura (Fujiwara 1960C, 1962), and Hoslett and Imaizumi (1966, 1967) it was shown that the season of reproduction for the Mogera species is usually limited in spring. However, in 2004 there were three young offspring of M. wogura in their nest in October within western Japan. There was a sexually active male and lactating female, both of the M. wogura species discovered in both September and October respectively.
