Abstract

Forensic DNA confirms intraguild killing of a chuditch (Dasyurus geoffroii) by a feral cat (Felis catus).

Abstract

Because animals killed by predators are often found partially consumed or decomposed, identification of the predator is often unachievable by post mortem examination. Forensic DNA offers an alternative in such situations. Using a novel method to analyse DNA from bite wounds on a freshly-killed chuditch Dasyurus geoffroii, we describe the first confirmed instance in this species of intraguild killing by a feral cat. Unlike post mortem examination, our method of DNA melt curve analysis is highly accurate and requires less time and expense than DNA sequencing.
