Table 8 Fixed effects and associated hypotheses (HA 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
