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

Fire Ecology

Table 11 Fixed effects and associated hypotheses (H_A from Table 5) in top models of adult buprestid or cerambycid activity across five bark beetle outbreak sites sampled in the greater Sierra Nevada region of California, USA, during the summer of 2016. QAICc = quasi-Akaike’s information criterion, corrected for small sample size; BA = basal area; Neg = negative; Pos = positive; DBH = diameter at breast height
