Sympatric prey responses to lethal top-predator control: predator manipulation experiments

Table 2 P values obtained from repeated measures ANOVA assessing differences in overall mean prey PTI (all surveys pooled) between baited and unbaited areas at nine sites across Australia (see Table 3 for seasonal breakdown)

* = Greater in baited areas; ^ = greater PTI in unbaited areas; NP = not present; ND = known to be present but not detected on tracking plots; NR = present and detected but not recorded; RE = mostly Varanus spp. and reported in [25]; X = insufficient data to calculate p; #N surveys for hopping-mice at Lambina = 5, error df = 4 for hopping-mice.
