| Abstract |
Theoretical, experimental and observational studies
have shown that biodiversity–ecosystem functioning (BEF) relationships
are influenced by functional community structure through two mutually
non-exclusive mechanisms: (1) the dominance effect (which relates to the
traits of the dominant species); and (2) the niche partitioning effect
[which relates to functional diversity (FD)]. Although both mechanisms
have been studied in plant communities and experiments at small spatial
extents, it remains unclear whether evidence from small-extent case
studies translates into a generalizable macroecological pattern. Here,
we evaluate dominance and niche partitioning effects simultaneously in
grassland systems world-wide. Two thousand nine hundred and forty-one grassland plots globally. 2000–2014. Vascular plants. We obtained plot-based data on functional community
structure from the global vegetation plot database “sPlot”, which
combines species composition with plant trait data from the “TRY”
database. We used data on the community-weighted mean (CWM) and FD for
18 ecologically relevant plant traits. As an indicator of primary
productivity, we extracted the satellite-derived normalized difference
vegetation index (NDVI) from MODIS. Using generalized additive models
and deviation partitioning, we estimated the contributions of trait CWM
and FD to the variation in annual maximum NDVI, while controlling for
climatic variables and spatial structure. Grassland communities dominated by relatively tall
species with acquisitive traits had higher NDVI values, suggesting the
prevalence of dominance effects for BEF relationships. We found no
support for niche partitioning for the functional traits analysed,
because NDVI remained unaffected by FD. Most of the predictive power of
traits was shared by climatic predictors and spatial coordinates. This
highlights the importance of community assembly processes for BEF
relationships in natural communities. Our analysis provides empirical evidence that plant
functional community structure and global patterns in primary
productivity are linked through the resource economics and size traits
of the dominant species. This is an important test of the hypotheses
underlying BEF relationships at the global scale. |
