Table 9 Fixed effects and associated hypotheses (HA from Table 5) in top models of adult buprestid activity across 11 burned sites sampled in the greater Sierra Nevada region of California, USA, during the summers of 2015 and 2016. QAICc = quasi-Akaike’s information criterion, corrected for small sample size; DOY = day of year; Neg = negative; Pos = positive; BA = basal area

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