|Abstract:||The southern hairy-nosed wombat (Lasiorhinus latifrons) appears to use scent marking, including defaecation, for social communication in the wild. This premise assumes that the receiver wombat is able to distinguish between faeces from different sources. To examine this theory, four types of faeces (male wombat, female wombat, dingo and a plastic control) were placed into the enclosures of 12 captive wombats. Behaviour, inter-individual distance and enclosure use were recorded during the period of placement, as well as the period before and the period after. When faeces were present, the wombats used concealed locations more often than other periods (mean %: pre-treatment: 71.3, treatment: 75.6, post-treatment: 72.7; P < 0.05). During the same period they also reduced grazing (mean min/period: pre- treatment: 15.8, treatment: 6.9, post- treatment: 13.1; P = 0.0002) and walking 2 activity (mean min/period: pre- treatment: 85.2, treatment: 66.9, post- treatment: 78.2; P = 0.01), indicating an increased perception of risk. Wombats approached the dingo faeces 5.6 times per treatment period, which was greater than for the control (3.0; P = 0.004) or female wombat faeces (3.7; P = 0.049). They also avoided other wombats most when male wombat faeces were present (8.3 retreats/period) compared to the control (4.5; P = 0.02), or female wombat (4.3; P = 0.01). There was a residual effect of increased wombat avoidance the period after presentation of dingo faeces (9.6; P ≤ 0.05). It is concluded that the southern hairy-nosed wombat can differentiate between faeces from different species and sex of conspecifics, and that predator faeces and those from male conspecifics increase wombat avoidance behaviour either during or after presentation.|
