Strongyloides callosciureus n. sp. (Nematoda: Rhabditoidea), from Asian sciurids, is described based on morphology, morphometry, and the small and large subunit (SSU/LSU) ribosomal RNA gene (rDNA) sequences. This new species was collected from Pallas's squirrels (Callosciurus erythraeus) in the central part of mainland Japan (Honshu), which were originally(More)
Enterobius (Enterobius) macaci Yen, 1973 (Nematoda: Oxyuridae: Enterobiinae) was collected from a Japanese macaque, Macaca fuscata, in Nara and Yamaguchi Prefectures, Honshu Island, Japan, for the first time. A redescription is presented along with DNA sequence data. This pinworm is a typical member of the subgenus Enterobius and is characteristic in the(More)
For the discrimination of the species of the genus Strongyloides, the shape of the stoma in the apical view of parasitic females is the most important feature. Microscopical interpretations divided the shape of the stoma into four groups (simple, angular, complex, and simple but with esophageal teeth); however, the stomas classified in the latter two(More)
Onchocerca eberhardi n. sp. from the sika deer, Cervus nippon, in Japan is described. Adult worms lived in the carpal ligament; infection reached high levels (up to 25 female and 16 male worms in a single carpal limb). Skin dwelling microfilariae were mainly found in the ears. Prevalence of infection was 81% at the type locality, Mt. Sobo, in Kyushu. The(More)
We investigated local geographical variation in the plant composition and quality (crude protein) of the diet of the Japanese serow (Capricornis crispus) by analyzing rumen contents. We collected the rumen contents from 111 Japanese serows culled for pest control between January and March 1997 in Shizuoka Prefecture, central Japan. The composition of the(More)
We performed a phylogeographic analysis of the Japanese hare, Lepus brachyurus, using the mitochondrial cytochrome b gene (1140 bp). In total, 119 haplotypes were recovered from 197 samples isolated from 82 localities on three main islands of the Japanese archipelago: Honshu, Sikoku, Kyushu, Sado Island and the Oki Islands. Results showed two distinct(More)
Nara Park, Nara Prefecture, Japan is a sightseeing destination in which people have the unique custom of feeding specialized cookies to the park’s free-ranging sika deer, Cervus nippon. Sika deer in Nara Park display a behavior akin to bowing to their human feeders. To characterize this bowing behavior and determine whether it is unique, we conducted(More)
