Tools to calculate functional diversity features.

Tool	Approach	Synopsis	Features	Reference
PHYLOCOM	Software	Calculates trait distribution to compare with random community consortia as well as uses evolutionary models to simulate trait and phylogenetic evolution	+ uses null models to test hypothesis of trait similarity + integrates trait information with evolutionary analysis + able to deal with polytomies	Webb et al. (2008)
FDiversity	Software	Focuses on calculation of functional diversity indexes and statistically analyze them	+ user friendly interface + accepts different input data formats	Casanoves et al. (2011)
FD	R-language package	Uses functional dispersion index and measures diversity based on distances of traits in a multidimensional space	+ allows missing values on calculation + allows weighting traits per abundance	Laliberté and Legendre (2010)
SYNCSA	R-language package	Uses matrix correlation to estimate trait patterns, phylogenetic signal and environmental variations for metacommunities	+ allows environmental characteristics to be considered	Debastiani and Pillar (2012)
cati	R-language package	Estimates community assembly patterns by species interactions and environmental filtering	+ allows differentiation among individuals + can integrate phylogenetic information into analysis	Taudiere and Violle (2016)
funrar	R-language package	Estimates functional rarity based on abundance and/or spatial frequency of species	+ estimates functional uniqueness, distinctiveness and taxon scarcity and restrictedness	Grenié et al. (2017)
