Calculates inter-community mean pairwise distance
Calculates MPD (mean pairwise distance) separating taxa in two communities, a measure of phylogenetic beta diversity
comdist(comm, dis, abundance.weighted = FALSE)
comm |
Community data matrix |
dis |
Interspecific distance matrix |
abundance.weighted |
Should mean pairwise distances separating species in two communities be weighted by species abundances? (default = FALSE) |
This function calculates a measure of phylogenetic beta diversity: the expected phylogenetic distance separating two individuals or taxa drawn randomly from different communities.
Distance object of MPD values separating each pair of communities.
