| Summary: | The management of dingoes (Canis lupus dingo) on Fraser Island presents a serious issue regarding the balance of public safety and world heritage conservation. One of the most important and least understood aspects of this issue is the availability of prey and prey species relations with the dingo diet. This relationship is the focal point of this research. To assess prey availability, three forest types were sampled during summer and winter 2005 using live trapping (12 sites) and track counting techniques (24 sites). Population estimations were obtained from statistical models (Nest) when possible, and with indices such as minimum number known to be alive (Ñ) and the Passive Activity Index (PAI). To investigate the diet of the dingo, 126 scats were collected. Prey remains were identified and the diet composition was described using presence-absence and weight of remains methods. The most common species in the study area were pale field rat and bush rat. The activity of rodents was different in the three ... |
