Results, first paragraph
There was a significant positive mean effect size across the meta-data set (Figure 1): on average, vertebrate predator removal or absence caused a 1.6 fold increase in the abundance of prey species.
Contexto
What changed: Lethal or physical removal and exclusion of vertebrate predators (mammalian and avian). Comparison: Areas or time periods where predators remained present. Limits: Substantial heterogeneity driven by predator taxon, prey group, and keepering methods, with confounding among study characteristics.
