Author response table 1. Four optimal models of landscape context, environment factors, and plant diversity affecting above-ground biomass.

Ranking	Model	R2	AICc
1	AGB~HL+SWT+GSR+WR	0.47**	1213.7
2	AGB~HL+FPS+SWT+GSR+WR	0.47**	1215.2
3	AGB~HL+LST+SWT+GSR+WR	0.47**	1215.3
4	AGB~FPS+SWT+GSR+WR	0.46**	1215.3

Note: AGB: above-ground biomass; HL: habitat loss; FPS: fragmentation per se; SWT: soil water content; LST: land surface temperature; GSR: grassland specialist richness; WR: weed richness; **: significance at the 0.01 level.”.
