Survival probability
We estimated a slight difference in the average survival rate when using CV versus CV+HSV in both species. In A. junius , using CV and CV+HSV, respectively, we estimated average survival probability to be 0.90±0.02 and 0.87±0.01, and in R. multicolor , we estimated average survival probability to be 0.84±0.02 and 0.88±0.03.
The two methods showed differences in the pattern of survival probability across age and wing length. Both methods showed a slight increase in survival probability with age in A. junius , although the mean was slightly overestimated using CV (Fig. 3a). However, different patterns were found in R. multicolor where CV showed a constant survival probability across age whereas CV+HSV showed a negative effect of age (Fig. 3b). In A. junius , CV showed a positive effect of wing length on survival probability whereas CV+HSV showed the opposite pattern (Fig. 4a). No significant effect of wing length on survival was detected for R. multicolor using both methods (Fig. 4b).
