Competitive reshuffling
The nature of community dynamics differed in the W global change
treatment. Instead of increased dominance and a decline in evenness,
species groups reshuffled in abundance whereby the dominant species
declined in cover over time, while subdominant and rare species
increased, and the cover of moderate species did not change (Fig 1,
Table 1). Furthermore, this was the only treatment where we
observed a change in the relative abundance of the rare species group
over time.
