Inter-group and -season variability in prey remains identified in wolf faeces. Wolf (Canis lupus) faeces collected during spring, summer and fall, pooled across 2001 to 2003 in coastal British Columbia. Local, Ochre, Mosquito and Mystery groups sampled in 2002 and 2003 only. Remaining groups were sampled in all 3 years. 'Other' are prey as identified in Table 1. Occurrence per faeces measures the frequency of occurrence of an item among total faeces of each group.
