Table 4.

Analysis‐of‐deviance table derived from linear mixed‐effects model of subplot biomass in monoculture by origin, exclusion treatment, emergence time, and density

	Biomass
	df	χ2	p
Origin	1	2.62	.11
Exclusion	2	27.51	<.001
Emergence	1	9.01	.003
Density	1	22.30	<.001
Origin × exclusion	2	2.34	.31
Origin × emergence	1	1.17	.28
Exclusion × emergence	2	28.63	<.001
Origin × exclusion × emergence	2	0.68	.71

Species nested within origin was treated as a random factor.
