  • Samples of two species of genus Ratts(black rat, Rattus rasttus Linnaeus; common rat, Rattus norvegicus Berkenhaut) in Korea were trapped and their 31 morphometric charcters were analyzed statistically in order to determine the range of geographic variation within each species and the interspecific differences. In addition, chromosomal G-bands and C-bands were compared and the fragment patterns of mtDNA resulted from the digestion with restriction enzymes were also analyzed. Samples of black rats from six localities in Korea were similar with one another in their morphometric characters: in head and body length, length of tail vertebrae, conventional karyotype and C-bands, they are comparable to Rattus rattus tanezumi in Japan. Specimens of common rats from seven localities in Korea were similar with one another in their morphometric characters: in conventional karyotype, they are comparable to Rattus norvegicus caraco in eastern Asia. Common rats differ from black rats in their morphometric characteris, chromosomal karyotypes and mtDNA. It is confirmed that correct species name of black rat in Korea is Rattus rattus tanezumi Tempminck: species name of common rat in Korea is Rattus norvegicus caraco Pallas: the common rat is a species, which is distinct from the black rat.

  • Forty samples of common rats (Rattus norvegicus caraco) from Cheongu, Korea, were used for the analyses of mitochondrial DNA (mtDNA) fragment patterns resulted from the digestion with eight restriction enzymes. A total of 36 fragments were recognized and six mtDNA clones were revealed . The nucleotide-sequence divergences (p) among six mtDNA clones ranged from 0.35% to 2.73%. moreover, the six clones were grouped into three major subgroups ; the first, second , and third subgroup were composed of 29 samples of three clones, ten samples of two clones, and one sample of one clone, respectively. The second and third subgroups were different in their mtDNa genotype of Pvu II from the first subgroup, and the third subgroup differed in the genotype of Dra I from other two subgroups. Futhermore, the maximum divergence among common rats from Korea in this study is greater than that among common rats from the United States and Japan by Brown and Simpson (1981). Further analyses with additional sample from other localities in Korea appeared to be necessary in order to clarify the taxnomic status of the distinct mtDNA subgroups.

  • The classification of the bone pieces excavated from Gasan-ri archaeological site 1 in Jinju, presumed to be relics was investigated macroscopically. The remains of the animal bone were 3 classes (Mammalia, Aves, Amphibia), 5 orders (Carnivora, Artiodactyla, Galliformer, Rodentia, Salientia), and 6 species (Sus scrofa, Cervidae sp., Nyctereutes procyonides, Phasianidae, Rattus norvegicus caraco, Rana nigromaculata). The total weight of the animal bone remains was 1,002.80 g, with the identified bones comprising 975.30 g and an identification rate of 97.26%. A total of 447 animal bone fragments were identified, including 204 bone pieces of S. scrofa (468.00 g, 47.99%), 102 bone pieces of Cervidae sp. (453.79 g, 46.53%), 68 bone pieces of R. nigromaculata (4.69 g, 0.48%), 59 bone pieces of N. procyonides (47.14 g, 4.83%), 9 bone pieces of Phasianidae (0.98 g, 0.10%), and 5 bone pieces of Rattus norvegicus caraco (0.70 g, 0.07%). The bone pieces of the animal relics consisted of 81 skull (18.12%), 161 axial skeleton (36.02%), 64 forelimb (14.32%), and 141 hindlimb (31.54%) fragments. The archaeological significance of the animal bones excavated in this investigation was that wild boars and deer were presumed to have been mainly used animals in the Gasan-ri area of Jinju during the Three Kingdoms period.

  • A survey on rodent damage to ripening rice was conducted in Sep.-Oct. in 1973 in order to indentify the habitat type which has the greatest influence on rodent populations and damage problems. Total 109 paddies were examined in three geographical regions in central part of Korea including Kangwon and Kyoungki Provinces, which represents mountainous, coastal and rice plain lands. Sample paddies were selected according to the neighboring or surrounding habitats as farm villages, upland-crop fields, grassy river banks, forests and rice plains. Snap trapping was also conducted in each of habitats. In April, 1974, field trips were taken to representative parts of Korea visiting farmers and rural guidance officers involving more than 100 people for the information of existing local problems. The general damage of rice was considerably low in 1973 averaging $63\%$ in early ripening varieties and $0.26\%$ in standard varieties, white the average lost in 1971 was $14.2\%$ in early ripening varieties and $2.7\%$ in standard varieties. But the most of severe damages was occurred within 50 meters (practically none beyond 100m) of farm villages, caused mainly by Norway rat (Rattus rottfus Caraco) and striped field mouse (Apodemus agrarius). The examples of existing local problems confirmed that the rodent damage to field crops is closely associated with rodent populations that have survived the winter in and around farm houses and buildings.

  • The patterns of serum proteins in seven species of Korean rodents were analyzed by immunoprecipitin, immunodiffusion, and immunoelectrophoresis. It is found that the serum proteins of each species were different with one another and thatntigenic divergence among the seven species seems to be enormous , ie., serological correspondence ranged from 99.6 in Rattus norvegicus caraco(suborder Myomorpha) to 2.7 in Tamias sibircus asiaticus (suborder sciuromorpha). In the six species of the family Muridae (Suborder Myomorpha), the lowest value of 8.2 was shown in Clethrionmys rufocanus regulus (Subfamily Microtinae).
