Table 5 Variation in density of heavily decayed snags in a slash pine (Pinus elliottii var. densa) forest in south Florida after experimental burning was best explained by the effect of pre-treatment snag density (baseline), fire-return interval (interval), and, to a lesser extent, season of burn (season). Evidence in support of additive or interactive effects among predictors was weak.

  1. a ΔAICc is the difference between each model’s AICc score and the score for the best model; models with lower AICc scores are better supported by the data.
  2. b Akaike weight provides an estimate of the likelihood that each model is the best model in the candidate set.
