cecropia R Documentation
Quantitative component of effectiveness for Cecropia glaziovii-frugivorous birds interactions.
Focal observations at Parque Estadual Intervales, Sao Paulo.
Pedro Jordano. 25 Mar 2012.
Description
Data from a field project during the Frugivory and Seed dispersal field course, 2012.
Usage
data(cecropia)
Format
A dataset (dataframe).
Details
Visitation data come from 140 h direct watches. A data.frame with 42 obs. of 37 variables.
First 6 variables are codes for Class, Order, Family, Genus, Species, and species label.
Variables include:
totvis- Number of visits recorded, pooled all trees.
totbic- Mean number of peckings to Cecropia catkins during a single visit. Birds do several peckings and ingest the seeds from these small pieces of the catkins. This may be used to estimate ingestion rate per visit.
sde- Effectiveness estimate for the quantitative component, totvis * totbic.
Columns 10-37 are the number of visits recorded to each individual Cecropia tree.
