However, a general picture of the relative extent of ITV compared to interspecific trait variation in plant communities is still missing. Here, we conducted a meta-analysis of the relative extent of ITV within and among plant communities worldwide, using a data set encompassing 629 communities (plots) and 36 functional traits. Overall, ITV accounted for 25\% of the total trait variation within communities and 32\% of the total trait variation among communities on average. The relative extent of ITV tended to be greater for whole-plant (e.g. plant height) vs. organ-level traits and for leaf chemical (e.g. leaf N and P concentration) vs. leaf morphological (e.g. leaf area and thickness) traits. The relative amount of ITV decreased with increasing species richness and spatial extent, but did not vary with plant growth form or climate. These results highlight global patterns in the relative importance of ITV in plant communities, providing practical guidelines for when researchers should include ITV in trait-based community and ecosystem studies. {\textcopyright} 2015 John Wiley \& Sons Ltd/CNRS.", optnote="Export Date: 16 November 2015", optnote="exported from refbase (http://php.ecofog.gf/refbase/show.php?record=637), last updated on Mon, 16 Nov 2015 18:22:09 -0300", opturl="http://www.scopus.com/inward/record.url?eid=2-s2.0-84946497490&partnerID=40&md5=4d012d3012031871ba890ca39b8084d7" }
