Population Structure and Mobility of the Scarce Copper Lycaena virgaureae in the Herb Meadow Habitat of Northern Mongolia

K.K. Barua, G. Chuluunbaatar and M. Muehlenberg    

Abstract: In the present study we aimed to investigate the population size and the dispersal ability of a common species Lycaena virgaurea within a natural herb meadow habitat in Northern Mongolia. Mark-release-recapture experiments were conducted during a 24 days study period between end of July and August in 2004. The total population size was estimated to be 2880 individuals and estimates of male and female populations showed no significant differences from a 1:1 ratio. Out of the 38.68% of all the marked individuals that were recaptured during the specified study period, the percentage of males recaptured atleast once were higher than those of the recaptured females (19.59:11.08). Mean distances moved between subsequent recaptures were significantly different for both the sexes (ANOVA, F (1,31) = 18.60; p<0.001). Mean distance between two successive captures in males and females were 141±129 and 89±85 m, respectively. The mean maximum distance moved by females was 705 m and by males was 633 m. The overall results indicated the restricted dispersal ability of the Scarce Copper (Lycaena virgaureae) within the study area inspite of large open populations of Lycaena virgaureae being supported within the natural landscape.
