Résumé
This thesis explores evidence for top-down suppression of an exotic mesopredator, the feral cat Felis catus, by a native apex predator, the dingo Canis dingo in an arid environment in Australia. I investigated this topic by examining the spatial distributions of these species as well as the potential for competition between them for shared prey. I found that both species overlapped spatially and selected for similar habitat features across the landscape. Dingoes and feral cats also exhibited a low level of dietary overlap. Together these findings suggest that dingo suppression of feral cats in this study system may be limited.
