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).
