1. Higher species diversity can improve community performance within a
species guild when different species complement each other in their use of
the available niche, such as through resource partitioning. However,
species in one guild of organisms may act as resources for another such
that the diversity in one guild alters the realized niche for species in
another. Yet, it remains largely untested as to whether diversity in one
guild of organisms influences species complementarity in another. 2. The
productivity and diversity in plant and arbuscular mycorrhizal (AM) fungal
communities can be positively associated with each other through their
typically mutualistic exchange of resources. Here we utilized these two
interacting species guilds to determine whether greater diversity in one
influences species complementarity in the other. This was done by creating
monocultures and a mixture of a grass, forb, and legume in a full
factorial design with monocultures and a mixture of four AM fungi. 3. The
presence of AM fungi reduced differences in the performance among plant
species and greater diversity of fungi generally improved plant
productivity over the average of the fungal monocultures. However, plant
species complementarity was not greatest with a higher diversity of fungi
and was only positive with a particular fungal monoculture. 4. AM fungal
abundance was not affected by plant diversity, but was greatly reduced in
the grass monoculture compared to the other plant communities. Variation
in fungal complementarity among plant communities was low overall and was
little influenced by plant diversity. 5. Synthesis. Using a model
plant-mycorrhizal system our results suggest that the composition rather
than the diversity of species within one guild may be more influential in
determining how species function within an associated species guild.
However, our model system does not represent a broad gradient of diversity
in either plant or fungal communities and only assesses the initial growth
phase. Nonetheless our results highlight that changes in species
compositions in one species guild can affect the functioning of species
diversity in another.
