Effects of personality on reproductive success in plateau pika Ochotona curzoniae
To clarify the effect of personality on reproductive success,the plateau pika Ochotona cur-zoniae 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 con-tent for ten microsatellite loci were 19.500,0.892,and 0.878,respectively. Based on microsatellite iden-tification and spatial capture location of the pikas,the parentage of 28 maternal parents and 140 off-springs,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 1370.100 cm and 1600.300 cm,respectively. The boldness and exploratory behavior of paternal parents had a significant effect on the number of off-springs,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.
