中文摘要:为阐明动物个性特征对繁殖成功率的影响,以高原鼠兔Ochotona curzoniae为研究对象,测定其个性特征,并通过微卫星DNA技术对高原鼠兔自然种群进行亲权鉴定。结果表明:10个微卫星位点的等位基因数量、期望杂合度和多态信息含量的平均数分别为19.500、0.892和0.878,通过微卫星鉴定与鼠兔的空间捕获位置确定了28只亲代母本和140只子代、20只亲代父本和137只子代的亲权关系,20只亲代父本和28只亲代母本的冒失性平均数分别为45.900 s和50.200 s,亲代父本和亲代母本探索性平均数分别为1 370.100 cm和1 600.300 cm。父本的冒失性和探索性对子代数量有显著影响,冒失性强和探索性强的父本子代数量更多,母本的冒失性和探索性对子代数量无显著影响,表明亲代的个性特征会影响子代的个性特征。 |

Abstract:To clarify the effect of personality on reproductive success, the plateau pika Ochotona curzoniae was selected as the study subject. Its personality were assessed, and parentage identification of the natural population of plateau pika was conducted using microsatellite DNA technology. The results showed that the average number of alleles, expected heterozygosity, and polymorphic information content for ten microsatellite loci were 19.500, 0.892, and 0.878, respectively. Based on microsatellite identification and spatial capture location of the pikas, the parentage of 28 maternal parents and 140 offsprings, as well as 20 paternal parents and 137 offsprings, was determined. The average boldness of the 20 paternal parents and 28 maternal parents was 45.900 s and 50.200 s, respectively, while the average exploration of the paternal and maternal parents was 1 370.100 cm and 1 600.300 cm, respectively. The boldness and exploratory behavior of paternal parents had a significant effect on the number of offsprings, with more offsprings from fathers with higher boldness and exploration. In contrast, maternal boldness and exploration did not significantly affect the number of offsprings. The results indicates that the personality of parents can influence the personality of their offsprings. |
