Fig 5. Relationships between stocking rate (i.e. stocking rate in yaks ha^-1 grazing season^-1) and liveweight gain (LG) of yaks (left y-axis, g yak^-1 d^-1) and area-based LG of yaks (right y-axis, g ha^-1 d^-1).

Solid lines show LG per yak (g yak^-1 d^-1), and long-dashed regression lines show LG per ha (concentrations × SR, g ha^-1 d^-1).Circles (●), triangles(▲), squares(■)and rhombuses (◆)represent the 2010, 2011, 2012 and 2013, respectively. Study site was located in an alpine meadow, Qinghai–Tibetan Plateau.
