Table 5. Effects of disturbance severity upon numbers of axillary branches and adventitious buds and shoots.

		Disturbance severity
		effect	test
Axillary branches	non-corrected	▾	72.7 (<1e-6)
Buds and shoots	corrected	▴	6.36 (0.0117)
	non-corrected	▴	6.55 (0.0105)

The responses of the numbers of axillary branches and buds and shoots to increasing severity of disturbance are presented graphically using up and down arrows. The test statistic is a likelihood ratio to be compared with a χ² distribution with one degree of freedom. Type I error estimate (significance) is shown in parentheses and the result shown in corrected row represents a model incorporating phylogenetic correction. The number of axillary branches character does not require correction, as it lacks phylogenetic signal (see Methods).
