Predator Exclusion

Grasshopper population changes (e.g., density, species composition) are examined when birds are excluded from multiple sites at the National Bison Range. The figure presents results for one site. Years falling below the dashed line indicate that grasshopper populations are enhanced by birds, while populations above the line are diminished by birds (see Belovsky & Slade 1993).
