Journal of Fish Biology   88 746-750   2015年1月   [査読有り]
© 2015 The Fisheries Society of the British Isles. The proportions of individual masu salmon Oncorhynchus masou whose genotypic and phenotypic sex differed were compared among juvenile and adult fish in three rivers, and genotypically male but phe...

© 2014, Springer Science+Business Media Dordrecht. Delineating population genetic structure and gene flow is a critical for identifying evolutionary processes and effective conservation. In this study, we examined the genetic structure of masu sal...

Journal of Fish Biology   84 256-262   2014年1月
This study compared the growth rates of female masu salmon Oncorhynchus masou, who possessed a male-specific gene marker, the growth hormone pseudogene (GHp), and normal females, as estimated from their scale growth. There was a difference between...

Mammalia   77 215-217   2013年5月
We performed microsatellite paternity analyses of two Asian black bear Ursus thibetanus littermates with a known mother. Using Cervus 3.0, we identified the probable father among 17 candidate fathers for Cub 1, but failed to identify a probable fa...

Ursus   23 218-225   2012年12月
We characterized annual and seasonal home ranges (HR) of 27 female Asiatic black bears (Ursus thibetanus) during 2003-11 in Karuizawa, Nagano Prefecture, Japan. Mean annual HR size for bears calculated by the 95% fixed kernel method was 10.0 km2 (...

Identifying the patterns and processes driving dispersal is critical for understanding population structure and dynamics. In many organisms, sex-biased dispersal is related to the type of mating system. Considerably, less is known about the influe...

Environmental Biology of Fishes   95 399-405   2012年10月
To clarify the spatial distribution of masu salmon Oncorhynchus masou with incongruent genotypic and phenotypic sex, we compared the phenotypic sex determined by gonad analysis with the genotypic sex identified by a male-specific genetic marker, G...

Conservation Genetics   13 1017-1026   2012年8月
Dam construction dramatically influences riverine ecosystems, with habitat fragmentation being one of the most serious impacts. This habitat fragmentation is particularly relevant for anadromous species such as salmonids. We examined the effects o...

Mammal Study   37 85-91   2012年6月
The Asian black bear inhabiting the Shimokita Peninsula, the northernmost part of Honshu, Japan, is categorized as one of the endangered local populations (LPs) in the list of threatened species under the Endangered Species Act. The Shimokita popu...

Journal of Fish Biology   80 378-386   2012年2月
The genetic sex of mature masu salmon Oncorhynchus masou (212 males and 243 females) collected from three rivers located in the mid-western part of Hokkaido was determined using the male-specific genetic marker growth hormone pseudogene (GHp). A t...
