Data from a study on Prunus mahaleb (Rosaceae) seed dispersal by frugivorous animals in SE Spain. Visitation data come from 107.3 h direct watches.
A dataset (dataframe).
# Visitation data come from 107.3 h direct watches. abundance- Mean no. birds censused/km, averaged for two study years.
visits- Mean no. visitis recorded to fruiting trees (/10 h).
prop_visits- Proportion of total visits recorded (feeding records) contributed by species. Relative to the total no. records in two study years.
eff_per_vis- Mean no. fruits swallowed per visit (successfully dispersed seeds).
eff_total- Visit rate * eff_per_vis*prop fruits swallowed.
prop_disp_service- Proportion of total dispersal service contributed by species.
