comdist function

Calculates inter-community mean pairwise distance

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)

Arguments

  • 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)

Returns

Distance object of MPD values separating each pair of communities.

Details

This function calculates a measure of phylogenetic beta diversity: the expected phylogenetic distance separating two individuals or taxa drawn randomly from different communities.
