Table 2. Model results (post-hoc tests) comparing hamster behaviour of the control and field group during tests 1 and 2 (before/after treatment) according to test phase.

Note:

Bold arrows indicate the direction of a significant difference (increase/decrease), while plain arrows indicate only a (non-significant) trend and hyphens indicate no change between tests. The number of arrows indicates if the difference is less than or equal to 0.05 (one arrow), 0.01 (two arrows) or 0.001 (three arrows). When under attack (phase 2), hamsters never explored the arena, as indicated by NA.
