Patterns of woodboring beetle activity following fires and bark beetle outbreaks in montane forests of California, USA

Fire Ecology

Table 8 Fixed effects and associated hypotheses (H_A from Table 5) in top models of larval woodborer activity across five bark beetle outbreak sites sampled in the greater Sierra Nevada region of California, USA, during the summers of 2015 and 2016. AICc = Akaike’s information criterion, corrected; Neg = negative; Pos = positive

Model rank	Predictor	Effect^a	ΔAICc	Δ_Null	H_A
1	Bark beetle activity	Neg^**	0.00	20.22	C
1	Needles retained	Neg^***	0.00	20.22	A
2	Needles retained	Neg^***	5.37	14.85	A
3	Bark condition = tight	Neg^***	7.73	12.49	A
3	Bark condition = missing	Neg^*	7.73	12.49	A
4	Broken-top tree = true	Pos^**	12.73	7.49	A
5	Bark beetle activity	Neg^**	13.90	6.32	C
