japanese wolves are genetically divided into two groups based on an 8-nucleotide insertion/deletion within the mtdna control region. | the mitochondrial dna (mtdna) control region (198- to 598-bp) of four ancient canis specimens (two canis mandibles, a cranium, and a first phalanx) was examined, and each specimen was genetically identified as japanese wolf. two unique nucleotide substitutions, the 78-c insertion and the 482-g deletion, both of which are specific for japanese wolf, were observed in each sample. based on the mtdna sequences analyzed, these four specimens and 10 additional japanese wolf samples could be classified ... | 2016 | 26853868 |
reconstructing the colonization history of lost wolf lineages by the analysis of the mitochondrial genome. | the grey wolves (canis lupus) originally inhabited major parts of the northern hemisphere, but many local populations became extinct. two lineages of wolves in japan, namely, japanese or honshu (c. l. hodophilax) and ezo or hokkaido (c. l. hattai) wolves, rapidly went extinct between 100 and 120years ago. here we analyse the complete mitochondrial genome sequences from ancient specimens and reconstruct the colonization history of the two extinct subspecies. we show a unique status of japanese wo ... | 2014 | 25132126 |
osteological and genetic analysis of the extinct ezo wolf (canis lupus hattai) from hokkaido island, japan. | the ezo wolf (canis lupus hattai kishida, 1931 ) is an extinct subspecies that inhabited hokkaido in japan until the middle of the meiji period. because there are very few preserved skeletons, no osteological and/or genetic analyses of the ezo wolf have been conducted. in this study, 20 cranial and eight mandibular characters were measured on ezo wolf skeletons, and mitochondrial dna (mtdna) was analyzed to assess genetic relationships between the ezo wolf and other wolf lineages, including the ... | 2010 | 20377350 |
computed tomography examination and mitochondrial dna analysis of japanese wolf skull covered with skin. | a canis skull, right half of the mandible and part of the left half of the mandible were subjected to three-dimensional (3d) computed tomography (ct) observation and mitochondrial dna (mtdna) analysis in order to determine whether the specimens belonged to the extinct japanese wolf, canis lupus hodophilax (temminck, 1839). osteometric analysis of the skull and right half of the mandible revealed that the material (jw275) was indeed typical of the japanese wolf. sequence analysis of a 600-bp mtdn ... | 2017 | 27746405 |
mitochondrial dna analysis of the japanese wolf (canis lupus hodophilax temminck, 1839) and comparison with representative wolf and domestic dog haplotypes. | mitochondrial dna (mtdna) d-loop control region sequences ranging in length from 583 to 598 bp were determined for eight japanese wolf specimens (canis lupus hodophilax temminck, 1839) collected from several sites and compared with 105 haplotypes from the domestic dog (c. lupus familiaris) and continental grey wolf (c. lupus lupus). also, a 197-bp mtdna sequence was amplified from archaeological wolf specimens and two continental wolf specimens (c. lupus chanco) as reference sequences for analys ... | 2009 | 19877836 |
osteometrical and ct examination of the japanese wolf skull. | the skulls of japanese wolf (canis hodophilax) were osteometrically examined and compared with those of akita-inu. the skull total length was not statistically different between two species. however, significant differences were demonstrated between two species in some ratios concerning the frontal bone. ct examination was carried out in the japanese wolf skull. the data indicated that the frontal sinus is not be largely developed and compressed in the dorso-ventral direction in parasagittal are ... | 1997 | 9271446 |
