| Abstract |
- The increased positive impact of plant diversity on
ecosystem functioning is often attributed to the accumulation of
mutualists and dilution of antagonists in diverse plant communities.
While increased plant diversity alters traits related to resource
acquisition, it remains unclear whether it reduces defence allocation,
whether this reduction differs between roots and leaves, or varies among
species.
- To answer these questions, we assessed the effect of
plant species richness, plant species identity and their interaction on
the expression of 23 physical and chemical leaf and fine root defence
traits of 16 plant species in a 19-yr-old biodiversity experiment.
- Only leaf mass per area, leaf and root dry matter
content and root nitrogen, traits associated with both, resource
acquisition and defence, responded consistently to species richness.
However, species richness promoted a decoupling of these defences in
leaves and fine roots, possibly in response to resource limitations in
diverse communities. Species-specific responses were rare and related to
chemical defence and mutualist collaboration, likely responding to
species-specific antagonists' dilution and mutualists' accumulation.
- Overall, our study suggests that resource limitation
in diverse communities might mediate the relationship between plant
defence traits and antagonist dilution.
