“…The Ho and He values were 0.3510 and 0.5724, respectively. These values are comparable to Yu's study on house mice in Taiwan, 21 which suggested that a mean of 3.17-8.50 alleles were found at six microsatellite loci, and the expected heterozygosity varied between 0.35 and 0.83. A previous study comparing genetic profiles of outbred with wild rats suggested that heterozygosity in Rj:SD, Crl:WIST and wild rats were 0.27 + 0.19, 0.41 + 0.19 and 0.35 + 0.21, respectively.…”

Kunming mice are the most widely used outbred colony in China. Differences in biological characters and drug reactions among different populations have been observed when using Kunming mice. But the molecular genetic profiles of Kunming mice and the extent of genetic differentiation among populations are unclear. Fifteen microsatellite markers were screened by a fluorescence-based semi-automated genotyping method for the two main populations of Kunming mice from Beijing (BJ) and Shanghai (SH) in China. The observed number of alleles, effective number of alleles, observed heterozygosity, unbiased expected heterozygosity and Shannon information index were used to estimate the genetic variation within the populations. A total of 89 alleles were detected in the two populations, with two to 12 at each locus, and the mean unbiased expected heterozygosity was 0.5724, which implies that there is abundant genetic variation in the populations of Kunming mice.

“…Slight reduction of heterozygosity (0.07) was observed in the F 1 inbred population. Such findings were comparable with Yu and Peng (2002) who observed that effective number of alleles and expected heterozygosity ranged from 3.17 to 8.50 and from 0.35 to 0.83, respectively for six microsatellite loci polymorphism study in house mice in Taiwan. Shang et al (2009) also studied the two Chinese Kunming mice population and observed that the mean number of alleles and mean of expected heterozygosity for each studied locus was 5.933 and 0.572, respectively.…”

Swiss albino mice have been widely utilized in various biological researches worldwide. Phenotypic and fitness related traits of F0 and F1 inbred mice were estimated on 918 and 707 individual offsprings, respectively. The influence of fixed effects (litter size and sex) on birth weight (BW), weaning weight (WW) and adult body weight (ABW) in both the generations were found to be statistically significant. Genetic characterization of F0 outbred and the F1 inbred strain of Swiss albino mice were evaluated by using 10 microsatellites markers. The results indicated that total number of alleles per locus ranged from 3 (D2Mit61, D3Mit55, D8Mit14, D9Mit27, D10Mit180, D11Mit167) to 4 (D1Mit15, D2Mit51, D5Mit18, D7Mit323) in F0 and F1 inbred population, with a mean value of 3.4 indicating polymorphism in all 10 loci. The mean of effective number of alleles was 2.935 and 2.733 in F0 and F1 population, respectively. Estimates of the FIS ranged from 0.139 (D10Mit180) to 0.999 (D9Mit27); and from 0.109 (D3Mit55) to 0.679 (D2Mit51) in F0 and F1 inbred population, respectively. The estimated mean markerbased FIS was 0.294 and 0.372 in F0 and F1 populations, respectively. The mean values of observed heterozygosity (Ho) and expected heterozygosity (He) were 0.460 and 0.654, respectively for F0 and 0.390 and 0.627, respectively for F1 inbred mice population. Slight reduction in heterozygosity and 7.8% increase in inbreeding coefficient were observed in F1 inbred in comparison to F0 population. The results suggested that genome wide microsatellite genotyping might be more useful for accurate measuring and reliable estimation of population genetic parameters and inbreeding coefficient.

“…The island's fauna is diverse and complicated as a result of its geographical history, with repeated isolation from and connection to the continent, and because of the topographical, climatic, and ecological diversity of the island. Several phylogenetic and phylogeographic studies were recently conducted on mammals (Yu and Peng, 2002), reptiles (Creer et al, 2001), amphibians (Yang et al, 1994), and fi shes (Wang et al, 2000(Wang et al, , 2004, and scenarios were proposed for the origin and formation of the fauna of Taiwan.…”

Comparative phylogeography of bagrid catfishes in Taiwan

et al. 2007

A phylogeographic analysis of two bagrid catfi shes in Taiwan was conducted using sequence data from a portion of the mitochondrial DNA (mtDNA) control region. For Pseudobagrus brevianalis, which is most probably endemic to Taiwan, a total of eight haplotypes were detected in 189 specimens from nine river systems covering its entire distribution range, from northern to central western areas of the island. Obvious genetic differentiation was observed among its populations (average F ST = 0.753); in particular, the northernmost Tamsui River population was fi xed for a single endemic haplotype. Nested clade phylogeographic analysis (NCPA) indicated that the dispersal center of mtDNA was the area around the Touchien River and Holong River, north to the Miaoli Plateau, in northwestern Taiwan, suggesting both northward and southward dispersal in this species. There was no evidence for the validity of P. taiwanensis, the nominal species described from Taiwan, morphologically similar to P. brevianalis. We confi rmed that P. adiposalis was distributed discontinuously in three river systems; analysis of 42 specimens from the rivers indicated a total of four haplotypes and population differentiation (average F ST = 0.876). Fixation into a largely differentiated haplotype in the northernmost Tamsui River population was also found in this species, but different processes for this phylogeographic pattern were implied for the two species. Comparison with P. ussuriensis, a widespread continental species morphologically similar to P. adiposalis, suggested the possibility that P. adiposalis is a group of local populations of P. ussuriensis in Taiwan. Two migration routes vs. random fi xation scenarios for the population structure of P. adiposalis are discussed with information on other fi shes and the geological history of the island.
