Notes:
The results of correlation between the ratio of the number of sound and holed
seeds in year N to that in year N - 2 (log transformed) and the
percentage of insect predation are shown. We test three types of the number
of seeds as in Appendix C.
Species
Seeds
of the same species
Seeds
of congeneric species
Seeds
of species that are assumed to share common predators
