relationship between uterine morphology and peripheral concentrations of sex steroid hormone in wild japanese black bears (ursus thibetanus japonicus).	developing a better understanding of the reproductive physiology and breeding condition peculiar to wild japanese black bears (ursus thibetanus japonicus) is crucial for estimation of their habitat distribution. the aim of this study was to clarify the changes in morphology of the genital organs, cellular proliferation in the endometrium and sex steroid hormone concentrations along with the reproductive cycle in japanese black bears. samples were collected from a total of 24 female japanese blac ...	2009	18790579
the first detection of babesia species dna from japanese black bears (ursus thibetanus japonicus) in japan.	in this study, we tried to detect protozoan blood parasites from the liver or blood of 156 japanese black bears (ursus thibetanus japonicus) in iwate prefecture of japan by polymerase chain reaction. two amplicons (approximately 540 bp and 480 bp) were detected by amplification for v4 hyper-variable regions of the 18s rrna gene. approximately 540-bp products were obtained in 119 samples (76.3%) and were considered to be dna of hepatozoon ursi. approximately 480-bp products were obtained in 22 sa ...	2011	21376138
long-term survey of cadmium and lead contamination in japanese black bears captured in iwate prefecture, japan.	cadmium and lead were measured in liver and kidney samples of 242 japanese black bears (ursus thibetanus japonicus) captured from 1999 to 2014 from two local populations in japan. the median concentration of cadmium was 0.54 (mean: 0.80) mg/kg-w.w. in liver and 7.7 (mean: 11.8) mg/kg-w.w. in kidney. the median concentration of lead was 0.24 (mean: 0.40) and 0.21 (mean: 0.32) mg/kg-w.w. in liver and kidney, respectively. bears in the kita-ou local population had higher concentrations of cadmium a ...	2016	27704187
