Mammal study 2021 v.46 no.4 pp. 1-7
ISSN:
1348-6160
Subject:
Talpidae; dogs; moles; shrews
Abstract:
... Dental anomalies in the greater Japanese shrew mole Urotrichus talpoides Temminck, 1841 (Eulipotyphla: Talpidae) were examined, based on 1001 specimens. We followed the dental formula of U. talpoides I 2/1, C 1/1, P 4/3, M 3/3 = 36, which is adopted by the most recent Japanese researchers, and found dental anomalies in 17 specimens involving 12 instances of absent tooth, four of extra tooth, and o ...

ISSN:

Subject:
beverages; bottles; cans; diet; feces; predators; rodents; shrews; small mammals; trapping
Abstract:
... We investigated the efficiency of discarded drink containers compared with other methods widely used in small mammal studies (live trapping and diet of generalist predators). We collected 225 beverage containers (bottles and cans) from 44 sampling places, and 376 small mammals of seven small mammal species were identified. Species accumulation curves emphasized significant differences between meth ...

Subject:
concrete; dams (hydrology); rivers; sediments; shrews; streams; surveys; Japan
Abstract:
... The concrete walls of check dams are considered a physical barrier for aquatic and semiaquatic animals that inhabit mountain streams. Traveling behaviors around concrete check dams by the Japanese water shrew Chimarrogale platycephalus, a semi-aquatic mammal, were directly observed via radio-tracking in Kamikoshi Stream in central Honshu, Japan. Traveling behaviors were mainly observed on the wet ...

Crocidura; DNA; cytochrome b; genes; heterozygosity; mitochondria; mitochondrial genome; mutation; nucleotide sequences; phylogeny; phylogeography; shrews; Japan; South Korea
Abstract:
... The Japanese white-toothed shrew (Crocidura dsinezumi) is a species endemic to Japan. For this species, only minimal phylogeographic investigations have been conducted. We obtained DNA sequences of mitochondrial cytochrome b and control region and nuclear ApoB genes for 191 individuals of C. dsinezumi from 107 locations collected throughout its known range. In the phylogenetic trees based on mitoc ...

5. Chromosomal Relationships between Two Species of Water Shrew, Chimarrogale platycephalus and Neomys fodiens

Subject:
Neomys; Y chromosome; cell nucleolus; chromosome banding; chromosome translocation; differential staining; interspecific variation; shrews
Abstract:
... The chromosomal relationships between the Japanese water shrew Chimarrogale platycephalus and the Eurasian water shrew Neomys fodiens were investigated by conventional and differential staining. From the side-by-side analysis of matching G-banding patterns from the two species, a high degree of G-band homology was recognized in most of the chromosomes that were compared, although the extent of suc ...

Abstract:
... A phylogenetic tree was reconstructed based on the mitochondrial cytochrome b gene nucleotide sequences of 169 individuals of house shrews (Suncus murinus and S. montanus) from 44 localities in East Asia, Southeast Asia, West Asia, and islands in the western Indian Ocean. Shrews from China (Zhejiang), Japan (Okinawa), Vietnam, and Indonesia (Java) formed a monophyletic group with less genetic vari ...

Araneae; Chilopoda; Collembola; Isopoda; Sorex; earthworms; field experimentation; forests; population density; predation; predators; shrews; soil; soil ecosystems; trophic levels
Abstract:
... In a soil ecosystem, bottom-up control is generally considered more influential than topdown control, although some empirical studies have suggested that predators have a trophic cascade effect on soil animals at lower trophic levels. In the present study, the effects of the long-clawed shrew, a mammalian predator at a high trophic level, on the soil invertebrate community and litter decomposition ...

Abstract:
... The Asian house shrew (Suncus murinus) is a commensal species whose has become widespread across the Old World due to human activities. This species has been well studied in captivity as a laboratory animal; however, in the wild, its ecological habits are not well investigated. We conducted radio-telemetry surveys to determine home range, habitat selection, and activity patterns of the Asian house ...
