Can we save flatback turtle nests from foxes?

By John-Michael Stuart.  Murdoch University is part of a joint effort in the State’s north-west to save a population of vulnerable flatback turtles from predation by foxes (see story). Along with Curtin University and the Department of Biodiversity, Conservation and Attractions (DBCA), we have been working with the pastoralist of the remote Mundabullangana Station.  Mundabullangana…

Runways and fancy feet – tracking escape paths of marsupials

By Natasha Tay.  Ever thought you’d spend two weeks in the bush giving bettongs rave party feet and putting them on a runway for science? I travelled to Arid Recovery in South Australia this past May to do exactly that. My PhD investigates anti-predator behaviour in marsupials, focussing on how anatomy affects their physical ability…

But a simpler kind of modelling is often used by behavioural ecologists who are interested in predation. If you wanted to…
