#' Quantitative component of effectiveness for Prunus mahaleb-frugivorous birds interactions.
#'
#' 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.
#' 
#' Variables include:
#'
#' # 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.
