Survival of Feral Cats, Felis catus (Carnivora: Felidae), on Mauna Kea, Hawai‘i, Based on Tooth Cementum Lines.

摘要: Feral cats (Felis catus) have spread throughout anthropogenic and insular environments of the world. They now threaten many species native wildlife with chronic depredation. Knowledge feral cat population dynamics is necessary to understand their ecological effects develop effective control strategies. However, there are few studies worldwide regarding annual or lifetime survival rates in remote systems, none on Pacific islands. We constructed age distribution estimated a area Hawai'i Island using cementum lines present lower canine teeth. Our data suggest line formation. A log-linear model ≥ 1 yr be 0.647. Relatively high coupled reproductive output allows individual affect for years populations rebound quickly after efforts.
