Principal coordinate analysis to reveal functional
(dis)similarities between taxa
After the assembly of the functional trait table, Principal Coordinate
Analysis (PCoA) of the species functional traits was used to construct a
‘functional trait map’ from the 204 taxa with complete set of trait
information. Distance matrix for PCoA was calculated with Gower distance
that allows different trait types (continuous, binary, categorical) to
be combined. Minimum and maximum length were log transformed before
calculating the distance. The first two principal coordinates were kept
in PCoA to create a 2D representation of the functional differences
between species.
