Fig 10. Patterns of vegetation biomass where differences among comparable experiments were attributable to reductions in pika abundance (interaction between experiment and period of pika reduction where implemented, P < 0.025).

Fig 10

Trend indicated by red lines are mean values from experiments in which pikas were reduced; blue lines from control experiments. A) Stipa purpurea, experiments in pastures of Pastoralist B (solid lines) and experiments 3 and 4 (dashed lines); B) S. purpurea in experiments in pastures of Pastoralist S (solid lines), and experiments 7 and 8 (dashed lines); C) Leymus secalinus, experiments in pastures of Pastoralist K (solid lines), and Pastoralist S (dashed lines); D) Carex spp., experiments 2 and 5; E) Kobresia spp., experiments 7 and 8; F) Heteropappus altaicus, experiments in pastures of Pastoralist B (solid lines), and 7 and 8 (dashed line); G) Potentilla bifurca, experiments 7 and 8 (solid lines) and in pastures of Pastoralist K (dashed lines); H) P. bifurca, experiments in pastures of Pastoralist B (solid lines), and Pastoralist S (dashed lines); I) Thermopsis lanceolata, experiments in pastures of Pastoralist S.
