摘要: Identifying landscape features and processes that facilitate the persistence of populations is particularly important for invasive mammal species, because it can focus management interventions on relatively small areas. We used camera traps to test predictions concerning relative abundance invading chital deer (Axis axis) seven cattle ranches in northern Australia: would be highest near permanent water homesteads, dingoes (Canis dingo) reduce deer. Distance from nearest homestead determined (as indexed by images per camera-day), with negligible > 4 km homesteads. In contrast, distance did not predict feral pigs (Sus scrofa), macropods, or dingoes. Abundance also declined increasing water, as pig abundance. There was no relationship between either macropod dingo water. The unaffected abundance, but 75–100% scats collected within 1 homesteads contained high abundances are likely due increased food quality quantity, protection dingoes, these hypotheses require further testing. conclude determinants distribution Australia (i.e., they “invasion hubs” this species). Our results suggest that, during dry season, managers should survey attempt control 3
