Predictive steady-state abundance distributions for each species group across observed gradients of ambient (left) and augmented (right) N deposition (zero centred ± two standard deviations) in global change plots, respectively (see Figure S9 for all treatments). Points show simulated equilibrium abundances (100 at each value of ×).

Maggie collaborated using gjamTime to understand dynamic species interactions in response to climate change. Density-dependent shifts in competitive interactions drove long-term changes in abundance of species-groups under global change while counteracting environmental drivers limited the growth response of the dominant species through density-independent mechanisms. Furthermore, competitive interactions shifted with the environment, primarily with nitrogen and drove non-linear abundance responses across environmental gradients [more]
