in the spiny and two in the non-spiny forest areas). Thus, we
considered only level 1 (undamaged coat) and 2 (moderately
missing fur) for the analyses and found that the proportion of
individuals with level-1 fur was significantly higher in the nonspiny
than in the spiny areas both in the analysis per forest
site (Exact Mann-Whitney U test, nnon-spiny=3, nspiny=6, Z=
-2.35, p=0.024) (Fig. 2) and in the analysis per group (Mann-
Whitney U test, nnon-spiny=31, nspiny=11, Z=-3.26, p=0.001).
