Managing Vertebrate Invasive Species
Cats (Felis catus) brought to Hawaii in the 1700s now occupy most habitats throughout the islands, including montane and sublapine zones. We studied home range, population genetics, diseases, and diet of feral cats on Hawai`i Island. Feral cats on Mauna Kea live in low densities and exhibit some of the largest reported home ranges. While 95% kernel home range estimates for 4 males ( x = 1418 ha) were nearly twice as large as 3 female home ranges ( x = 772 ha), one male maintained a home range of 2050 ha. Population genetics revealed that Mauna Kea …

Managing Vertebrate Invasive Species
The endemic fauna of New Zealand evolved in the absence of mammalian predators and their introduction has been responsible for many extinctions and declines. Predator control will have to be on-going if some native species are to survive on the mainland. Currently, predator control relies largely on labourintensive trapping, so the development of humane predator-specific toxins would provide valuable additional control methods. Para-aminopropiophenone (PAPP) is being investigated as a toxin for feral cats (Felis catus), stoats (Mustela erminea), and wild dogs (Canis familiaris). Carnivores appear to be much more susceptible to PAPP than birds, …
