Figure 6. Interval times (in seconds) across three habitat types (OPEN, SPARSE vegetation, DENSE vegetation). (a) time from start of pursuit to first bullet impact; (b) time from first bullet impact to incapacitation; (c) time from first shot to incapacitation; (d) time from pursuit to incapacitation.
The evidence for an effect of habitat type in which first seen and species on the time intervals (Fig. 6) varied depending on the interval used as the response variable. There was no evidence for any effect on the time between pursuit and impact, but a moderate effect of both habitat and species on the time between being shot and incapacitation (driven mainly by differences between the two species) (Table 2). The two remaining response variables (time between impact and incapacitation; time between pursuit and incapacitation) had comparatively weak effects of both variables, with approximately equal contributions of both for the former, and habitat type for the latter (Table 2).
Table 2. Top-ranked subset of the generalised linear models to test for the effects of habitat where first seen (H) type (open, sparse, dense [vegetation]) and species (S) (pigs or deer) on the time intervals between pursuit and impact, impact and incapacitation, shot and incapacitation, and pursuit and incapacitation. * denotes an interaction term. k = number of model parameters; 𝓁 = -log likelihood; AICc = Akaike’s information criterion corrected for small sample size; wAICc = model probability; %DE = percent deviance explained.
