Figure 1.
Mean soil moisture across sites (±SE).
The bars represent the soil moisture data taken on 8 occasions during 34 day sampling period.
Table 1.
Optimal generalized additive mixed model: feeding as a function of moisture, location, bait flavour and depth.
Figure 2.
Feeding activity for each bait flavour across the five sampling sites in Wytham Woods.
The black dots represent the median, with the boxes representing the 25th and 75th percentiles. The range is given by the whiskers.
Figure 3.
Feeding activity at different depths below the soil surface.
The proportion is total number of holes perforated at each depth, averaged across bait flavours and plots within each site. The smoothers are derived from the generalised additive mixed model (see Statistical analysis). The model validation showed that the N100m and S100m sites could be described with one smoother as could the SE and NE sites.
