Figure 3. Posterior mean population sizes
(Nks ± 95% CI) for quoll-invaded and quoll-free
populations of grassland melomys (Melomys burtoni ) on Indian
Island, Northern Territory, Australia. The orange dotted vertical line
denotes the timing of the introduction of quolls. The red dotted
vertical line denotes the timing of an unplanned fire that burnt through
the quoll-invaded sites. In each predator treatment, different sites are
denoted by different shaped points. Estimates assume closure of the
population within each session and detection probability that varies
across sessions.
