This readme file describes the data from the master table for co-occurrence results for the above publication. The same table was used when conducting the linear-mixed model described in that publication. For any further queries please contact marcia.waterway@mcgill.ca.

Standardized effect sizes of co-occurrence (ses_cooccur) are given for each species pair (sp_pair) at each fen, as are the observed number of co-occurrences (obs_cooccur) and the expected number of co-occurrences (exp_cooccur. Prob_cooccur gives the probability that both species occur at a site, probability_aversion the probability of co-occurrence at a frequency less than the observed number of quadrats if the two species were distributed randomly of one another and probability_attraction the probability of co-occurrence at a frequency greater than the observed frequency. Environmental variables are summarized as rooting_level_d for the mean delta rooting level (cm) and ph_d for the mean delta pH. The Box-Cox transformations of both variables are given as rooting_level_d_bc and ph_d_bc, respectively. The phylogenetic distances between species pairs using the trees from the MrBayes and the BEAST analyses are given as dBEAST and dBayes, respectively. Two factors code for the clade divergence levels (CDL): CDL1 and CDL2.

Fens of the Schefferville region (54º 47’N 66º50’W) are labelled by the first two letters of the name of the fen where the data were collected. Full fen names are given in Table 1 of the manuscript. Species are labeled using the first letter of the genus (uppercase) and first three letters of the species (lowercase). Full species names are given in Table 3 of the manuscript.
