- Functional traits offer promising avenues to investigate
how community composition and diversity define ecosystem functioning
and service delivery. In recent years, many empirical studies on the
importance of functional traits for ecosystem service provisioning have
been undertaken, but a general understanding and synthesis of results is
lacking for many ecosystems.
- Here, we focus on temperate grasslands and present a
systematic literature review synthesizing how plant functional traits
are interrelated with ecosystem services.
- Based on 109 studies, we identified a core set of 40
functional traits and eleven ecosystem services. Several of these traits
were only linked to one, while 75% of traits were linked to two or more
- We found that trait‐specific constraints can lead to
both synergies and trade‐offs in the supply of multiple ecosystem
services. For instance, synergies between biomass production and climate
regulation can be achieved by changing morphometric root traits such as
increasing root diameter, tissue density or shoot to root ratio. On the
other hand, supporting fast‐growing exploitative species characterized
by high specific leaf area and nitrogen content typically leads to
trade‐offs between fodder quality and water purification.
- Synthesis and applications. By applying network
analysis, we found five groups of ecosystem services sharing common
functional traits. Within and among these groups, we identified
trade‐offs among traits as well as among services and found options for
synergies. These can be particularly useful in landscape planning, and
when management aims focus on maintaining multifunctionality of
ecosystems and maximizing corresponding ecosystem service delivery.
