- We have previously found that plant communities respond systematically to global change drivers around the world, however the consequences for functional differences have yet to be investigated in a large-scale synthesis.
- Here we find that productivity responses to experimental global change drivers are initially driven by physiological responses of the existing plant community, followed by reordering of species within a community, and finally species turnover (losses and immigration). This result provides support for the Hierarchical Response Framework (Smith et al 2009).
Guidance for improving herbaceous community dynamics in Earth System Models.
Lead authors: Kevin Wilcox, Kimberly Komatsu, Meghan Avolio
- Earth system models (ESM) are powerful tools to predict ecosystem functioning. However, few ESMs incorporate vegetation change, and those that do, only capture coarse changes.
- Here we demonstrate that current approaches of representing community change into Earth system models often do not match observations, particularly for grasslands, using an example from a long-term resource manipulation experiment in tallgrass prairie. We also discuss commonalities in empiricist and process-based modeler goals and differences in approaches to obtain these goals. Finally, we present a roadmap for better incorporation of occurrences and impacts of community changes into ESMs.

- Ecosystem stability is important for maintaining ecosystem services and are likely to be impacted by global change drivers. We are investigating how global change drivers alter meta-community (beta) diversity, which then scales up impact two important contributors to ecosystem (gamma) stability.
- We find that beta-diversity is a strong driver of population synchrony . This effect is consistent across a wide array of global change drivers.
Grassland plant communities with high rates of background change show greater change with GCDs
Lead authors: Sally Koerner, Kimberly Komatsu, Meghan Avolio
- Plant communities are continuously changing over time. These background rates of change are poorly understood and can have large impacts on system response to global change drivers.
- Some plant communities exhibit higher rates of background change than others, and these communities were more responsive to global change treatment manipulations.
