Quantitative component of effectiveness for Prunus mahaleb-frugivorous birds interactions.

Description

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.

Usage

data(prunus)

Format

A dataset (dataframe).

Details

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.
