Table 1.
Nutritive and mineral mean (±SE) contents of offered wholemeal feed, and food remaining after red deer hinds fed for 1 and 5 hours.
Table 2.
Meal components (mean ±SE) and selection indices during the 1st feeding hour.
Figure 1.
Experimental design for the ‘Restricted food access’ experiment.
Only 6 hinds at most are allowed to feed at once. Location of video cameras and their visual field is shown.
Table 3.
Meal components (mean ±SE) and selection indices from 1st to 5th hours.
Figure 2.
Plotting of T/n (mean time per feeding bout, log- transformed to achieve normality) vs. normalized social rank (ArcsenSqrt of hierarchical social rank; Côté 2000), with linear (solid line; R = 0.11; P = 0.230) and quadratic (dashed line; R = 0.44, P = 0.011) adjusting.
Table 4.
One-way Pearson correlations among social rank and food access behavioral indices (T/n = mean time per feeding bout; FFB = time to first feeding bout; AO = order of access to the feeder; TFB = total number of feeding bouts; FT = time spent feeding during the first hour; N = 44).
Figure 3.
Influence of the energy on the observed standarized selection ratios during first feeding hour (Bi0–1; black triangles and solid line; R = 0.79) and first to fifth (Bi1–5; hollow triangles and dashed line; R = 0.68).
Note the different slopes, which indicate a lower selectivity in the second period when the amount of food available was lower.
