  • 한국에 서식하고 있는 붉은쥐속 2 종, 등줄쥐(Apodemus agrarius coreae, A. agrarius chejuensis)와 흰넓적다리 붉은쥐 (A. peninsulae peninsulae)의 염색체 및 형태적 형질의 분석을 하였다. A. agrasius coreae는 작은 형이고, A. agrarius chejuensis 와 A .peninsulae peninsulae 는 큰 형이었다. 또한A. agrarius chejuensis 는 A.peninsule peninsulae 보다도 큰 편이었다. A.peninsulae peninsulae 에 있는 B chromosomes 은 C.-negative 즉 진정염색질임이 밝혀졌다.

  • Striped filed mice from Jeju-Do (Apodemus agrarius chejuensis) were used for morphometric and chromosomal studies in order to compare them with striped field mice from the korean peninsula (A. Agrarius coreae). It was found that A.agrarius chejuensis and A. agrarius coreae are similar in karyotypes and it was confirmed that the former is a large-size group and the latter is a small-size group.

  • Univariate and multivariate analyses of morphometric characters were performed with samples of three subspecies of striped field mice (Apodemus agrarius coreae, A. agrarius pallescens, and A. agrarius chejuensis). It was found that the samples of A. agrarius chejuensis from Jeju-Do were distintc from those of the other two subspecies from the Korean peninsular, whereas subspecies coreae was similar to subspecies pallescens: it is concluded that A. agrarius pallescens is a synonym of A. agrarius coreae. Further analyses will be needed to clearify the subspecific status of A. agrarius chejuensis.

  • It has been confirmed that two dendrograms resulted from two similarity matrices, average taxonomic distance and correlation coefficient matrices, are different with each other when cluster analyses were performed with 571 adults of deer mice, Peromyscus maniculatus using 30 morphometric characters. To choose one of two similarity matrices mentioned above in order to construct a dendrogram representing phenetic relationships among taxa, an objective method using the result from principal component analysis as a standard result to compare with two matrices has been suggested.

  • Objective: The present study is aimed at phenotypic characterization and mitochondrial d-loop analysis of indigenous "Diara" buffalo population, which are mostly confined to the villages on the South and North Gangetic marshy plains in the Bihar state of India. These buffaloes are well adapted and are best suited for ploughing and puddling the wet fields meant for paddy cultivation. Methods: Biometric data on 172 buffaloes were collected using a standard flexible tape measure. Animals are medium in size; the typical morphometric features are long head with a broad forehead and moderately long and erect ears. Genomic DNA was isolated from unrelated animals. The mtDNA d-loop 358-bp sequence data was generated and compared with 338 sequences belonging to riverine and swamp buffaloes. Results: Based on the mitochondrial d-loop analysis the Diara buffaloes were grouped along with the haplotypes reported for riverine buffalo. Sequence analysis revealed the presence of 7 mitochondrial D loop haplotypes with haplotype diversity of 0.9643. Five of the haplotypes were shared with established swamp breeds and with Buffalo population of Orissa in India. Conclusion: Morphometric analyses clearly shows distinguishing features like long and broad forehead which may be useful in identification. The germplasm of Diara buffalo is much adapted to the marshy banks of river Ganga and its tributaries. It constitutes a valuable genetic resource which needs to be conserved on priority basis.
