In phyr: Model Based Phylogenetic Analysis

Description Usage Format

A list containing a phylogeny for XX species of Oldfield forbs, as well as a presence / absence dataset for their occurrence across several locations in Southern Ontario see Dinnage (2009) for details. Sites each had two plots which experienced a different treatment each; either they has been disturbed (ploughed 1 or 2 years previously), or they were a control plot (undisturbed in recent records).

abundance: integer. Recorded abundance of species in plot.
disturbance: integer. Whether the plot was disturbed or not. 0 or 1. 0 for undisturbed, 1 for disturbed
site_orig: character. A unique site descriptor concatenating the site number with the disturbance treatment.
