| a molecular phylogenetic framework for the ryukyu endemic rodents tokudaia osimensis and diplothrix legata. | diplothrix legata and tokudaia osimensis are rodent species endemic to the ryukyu islands (okinawa area) of the southern part of japan. to place them within a phylogenetic framework of asian rodent species, we examined the molecular relationships among these species and apodemus, micromys, mus, and rattus, using an analysis of mitochondrial cytochrome b gene (1140 bp) and nuclear irbp gene (782 bp) sequences. the results indicate that the four main murine genera and tokudaia diverged at similar ... | 2000 | 10764531 |
| angiostrongylus cantonensis (nematoda: metastrongylidae) in the ryukyu islands tree rat (diplothrix legata). | angiostrongylus cantonensis is a zoonotic nematode with rodents serving as natural definitive hosts. we report a. cantonensis in the ryukyu islands tree rat (diplothrix legata, thomas, 1906), a native endangered species in japan. adult and larvae of a. cantonensis were macroscopically, histologically, and genetically detected in three tree rats collected between august 2011 and january 2012 in the yambaru area of okinawa prefecture, japan. pathologic observations of the lungs of rats showed that ... | 2014 | 24499332 |
| reproductive traits of the ryukyu long-furred rat (diplothrix legata) on okinawa-jima island. | the ryukyu long-furred rat, diplothrix legata, is a large rodent distributed only on amami-ohshima island, tokuno-shima island and okinawa-jima island, japan. this animal is endangered as a result of deforestation, predation by introduced carnivores and mortality caused by vehicles. we performed theriogenological examinations of 32 male and 25 female ryukyu long-furred rats carcasses collected from wild populations on northern okinawa-jima island from december 2005 to september 2013. adult males ... | 2015 | 25649850 |
| alien parasitic infections in the endangered ryukyu long-furred rat (diplothrix legata) on amami-oshima island, japan. | there is limited knowledge about parasites of the endangered ryukyu long-furred rat, diplothrix legata (murinae, rodentia) endemic to okinawa, tokunoshima, and amami-oshima islands in japan. in the present study, postmortem histopathological examination of an individual found on amami-oshima island revealed a mixed helminth infection of calodium hepaticum, hydatigera taeniaeformis, and angiostrongylus cantonensis. these helminths are considered non-native to amami-oshima island and are maintaine ... | 2020 | 31958570 |
