Floral symmetry, visitation, and sharing

This repository contains data and scripts supporting

Yoder JB, G Gomez, and CJ Carlson. Zygomorphic flowers have fewer visitors. bioRxiv, doi: 10.1101/743872

Floral visitation data are derived from records archived in the Web of Life and Interaction Web DataBase repositories; source datasets and the repositories where each were obtained are given in data/references_all.csv.

output

Files containing data derived from compiling source data

• plant_degree-sharing.csv --- floral symmetry, visitor count, and visitor sharing for all plant species
• whole-matrix_stats.csv--- network structure statistics for all plant-visitation networks in the dataset
• sub-matrix_stats.csv --- network structure statistics for all plant-visitation networks, divided into sub-networks based on plant floral symmetry
• working_tree.tre --- time-calibrated phylogeny of 2509 plant taxa in the dataset, pruned from the "ALLMB" supertree constructed by Smith and Brown (2018)
• degree_per_plant_phy.csv --- floral symmetry, visitor count, and visitor sharing for 2509 plant species, with principal components of the phylogenetic distances among them, based on the phylogeny in working_tree.tre
• figures --- sub-folder containing all figures
