Table 1.

Variables and data used to calculate community-weighted means for observed and alternative trait models

Community-weighted mean	Species set	Abundance values	Trait values
CWM2014	All	Final	Final
CWM2011	All	Initial	Initial
CWMTURNOVER	Constant	Final	Final
CWMABUNDANCE	Constant	Initial	Final
CWMITV	Constant	Final	Initial

‘All’ refers to all species that occurred on the plot. ‘Constant’ refers only to those species which were present in both 2011 and 2014. ‘Final’ refers to abundance or trait values measured in 2014, while ‘Initial’ is abundance or trait values measured in 2011.
