| Abstract | The global loss of
biodiversity has motivated many studies that experimentally vary plant
species richness and examine the consequences for ecosystem functioning.
Such experiments generally show a positive relationship between above-
and below-ground biodiversity and the functioning of terrestrial
ecosystems. Moreover, this relationship tends to strengthen over time,
seen as enhanced functioning of diverse plant communities and reduced
functioning of low-diversity plant communities. Differences in
multitrophic community assembly and biotic interactions in high- versus
low-diversity plant communities are hypothesized to affect plant
performance by altering consumer community structure and function and
driving plastic or micro-evolutionary responses of plant species in the
plant communities. To resolve this complex interplay of community
history, we separated these effects into plant and soil history. Plant
history refers to all plant-level responses to past abiotic and biotic
selection pressures experienced in their communities, while soil history
relates to all abiotic and biotic soil properties developed as a legacy
of plant-soil interactions under variable plant diversity. We set up a
biodiversity experiment in an Ecotron, a terrestrial mesocosm facility
that allows controlling environmental conditions above- and
below-ground, to test whether the strengthening biodiversity-ecosystem
functioning relationship is due to soil history, plant history, or a
combination of both. We established a plant diversity gradient
consisting of 1, 2, 3, and 6 grassland plant species and factorially
nested with soil history and plant history treatments for each level of
plant species richness. Representative results demonstrate the
successful establishment of target treatments in the Ecotron experiment,
observing the effects of plant and soil history on initial plant
development and final plant growth. Additionally, we provide a case
study for data analysis of individual response variables. We outline
research objectives and methods to comprehensively assess the
multifunctional responses to the experimental treatments necessary to
ultimately address the overarching hypothesis. |
