Biotic interactions, community assembly, and eco-evolutionary dynamics as drivers of long-term biodiversity–ecosystem functioning relationships.
RIO 5:e47042 (2019)
The functioning and service provisioning of ecosystems in the face of
anthropogenic environmental and biodiversity change is a cornerstone of
ecological research. The last three decades of biodiversity–ecosystem
functioning (BEF) research have provided compelling evidence for the
significant positive role of biodiversity in the functioning of many
ecosystems. Despite broad consensus of this relationship, the underlying
ecological and evolutionary mechanisms have not been well understood.
This complicates the transition from a description of patterns to a
predictive science. The proposed Research Unit aims at filling this gap
of knowledge by applying novel experimental and analytical approaches in
one of the longest-running biodiversity experiments in the world: the
Jena Experiment. The central aim of the Research Unit is to uncover the
mechanisms that determine BEF relationships in the short- and in the
long-term. Increasing BEF relationships with time in long-term
experiments do not only call for a paradigm shift in the appreciation of
the relevance of biodiversity change, they likely are key to
understanding the mechanisms of BEF relationships in general. The
subprojects of the proposed Research Unit fall into two tightly linked
main categories with two research areas each that aim at exploring
variation in community assembly processes and resulting differences in
biotic interactions as determinants of the long-term BEF relationship.
Subprojects under “Microbial community assembly” and “Assembly and
functions of animal communities” mostly focus on plant diversity effects
on the assembly of communities and their feedback effects on biotic
interactions and ecosystem functions. Subprojects under “Mediators of
plant-biotic interactions” and “Intraspecific diversity and
micro-evolutionary changes” mostly focus on plant diversity effects on
plant trait expression and micro-evolutionary adaptation, and subsequent
feedback effects on biotic interactions and ecosystem functions. This
unification of evolutionary and ecosystem processes requires
collaboration across the proposed subprojects in targeted plant and soil
history experiments using cutting-edge technology and will produce
significant synergies and novel mechanistic insights into BEF
relationships. The Research Unit of the Jena Experiment is uniquely
positioned in this context by taking an interdisciplinary and
integrative approach to capture whole-ecosystem responses to changes in
biodiversity and to advance a vibrant research field.
