Figure 5. (a) Effect of estimated population size on the number of control, unscented seeds removed from seed plots (n = 21) in quoll-invaded and quolls-free sites. Dotted lines denote the effect of quoll presence on seed removal rate. (b) Mean (± 95% CI) difference (Δ) between the number of predator-scented seeds and control, unscented seeds removed by melomys from quoll-invaded (n = 3; 2017 &n = 4; 2018-19) and quoll-free (n = 4; 2017 & n = 3; 2018-19) sites during each trapping session.
