| Abstract |
- Nutrient enrichment impacts grassland plant diversity
such as species richness, functional trait composition and diversity,
but whether and how these changes affect ecosystem stability in the face
of increasing climate extremes remains largely unknown.
- We quantified the direct and diversity-mediated
effects of nutrient addition (by nitrogen, phosphorus, and potassium) on
the stability of above-ground biomass production in 10 long-term
grassland experimental sites. We measured five facets of stability as
the temporal invariability, resistance during and recovery after extreme
dry and wet growing seasons.
- Leaf traits (leaf carbon, nitrogen, phosphorus,
potassium, and specific leaf area) were measured under ambient and
nutrient addition conditions in the field and were used to construct the
leaf economic spectrum (LES). We calculated functional trait
composition and diversity of LES and of single leaf traits. We
quantified the contribution of intraspecific trait shifts and species
replacement to change in functional trait composition as responses to
nutrient addition and its implications for ecosystem stability.
- Nutrient addition decreased functional trait
diversity and drove grassland communities to the faster end of the LES
primarily through intraspecific trait shifts, suggesting that
intraspecific trait shifts should be included for accurately predicting
ecosystem stability. Moreover, the change in functional trait diversity
of the LES in turn influenced different facets of stability. That said,
these diversity-mediated effects were overall weak and/or overwhelmed by
the direct effects of nutrient addition on stability. As a result,
nutrient addition did not strongly impact any of the stability facets.
These results were generally consistent using individual leaf traits but
the dominant pathways differed. Importantly, major influencing pathways
differed using average trait values extracted from global trait
databases (e.g. TRY).
- Synthesis. Investigating changes in multiple
facets of plant diversity and their impacts on multidimensional
stability under global changes such as nutrient enrichment can improve
our understanding of the processes and mechanisms maintaining ecosystem
stability.
