Karyosystematic Analysis of Japanese Talpine Moles in the Genera Euroscaptor and Mogera (Insectivora, Talpidae)
TLDR
It is deduced that pericentric and paracentric inversions in four pairs of acrocentrics would explain the karyotype differences between the Japanese and Korean populations, and it is concluded that the Korean mole was derived from primitive M. wogura through four inversions, quite separately from the lineage of M. tokudae.

Analysis of dental anomalies in the Siberian mole, Talpa altaica (Insectivora, Talpidae).
TLDR
Tooth variation in specimens of the Siberian mole, Talpa altaica, from the collection of the Siberia Zoological Museum is re-examined and the mechanisms of dental evolution are discussed. Expand
Phylogenetic Relationships among East Asian Species of Crocidura (Mammalia, Insectivora) Inferred from Mitochondrial Cytochrome b Gene Sequences
TLDR
Phylogenetic relationships among the East Asian species of the genus Crocidura (Mammalia, Insectivora, Soricidae) were inferred from the partial sequences of the mitochondrial cyto-chrome b gene, suggesting the non-monophyly of the species as of the present definition. Expand
Premolar and molar rotation in wild Japanese serow populations on Honshu Island, Japan.
TLDR
It is concluded that genetic differentiation occurred in the past among local Japanese serow populations isolated in mountainous habitats and Gene frequencies were likely subject to random drift, especially during possible population bottlenecks. Expand
Variations in the number of teeth in wild Japanese serow (Naemorhedus crispus).
TLDR
Results indicate that the phenomenon of tooth degeneration does not only occur at the end of a tooth row, and variations in the number of teeth in Japanese serow were concordant with their phylogenetic background. Expand
Quest for the cause of oligodontia in Suncus murinus (Soricomorpha, Soricidae): Morphological re-examination.
TLDR
It is believed that oligodontia in S. murinus depends on odontogenetic factors, and osteological factors do not account for the absence of P(3) and I(3). Expand
[Numerical anomaly of teeth in mongrel juvenile dogs. Canis familiaris].
TLDR
This investigation suggests that tendency of the reduction of the upper third premolar was considered to be caused by the reductionof the maxilla through the process of domestication, and results are inconsistent with Fujita's terminal reduction theory. Expand
Numerical variation of teeth in the wild house musk shrew Suncus murinus captured from Nagasaki, Japan.
TLDR
It is suggested that the high rate of postnatal absence of teeth in the wild population of S. murinus is due to oral diseases such as periodontal disease or other traumatic factors. Expand
Geographical Variations in Chromosomes of the Greater Japanese Shrew-Mole, Urotrichus talpoides (Mammalia: Insectivora)
TLDR
The results demonstrated that the clear boundary between the two parapatric karyotypic races was actually located along the Kurobe-Fuji line in the central part of Honshu, but not along the Owari-Tsuruga isthmian line previously postulated by Tsuchiya (1987, 1988). Expand
Pattern of X-Y chromosome pairing in the Japanese field vole, Microtus montebelli.
TLDR
Pairing of X and Y chromosomes at meiotic prophase in males of Microtus montebelli was analyzed and it is suggested that the sex chromosomes of M. monte Belli and M. oeconomus display the ancestral type of X-Y pairing. Expand
