A. Schematic representation of the experimental arena. B. Arena showing the simulated M. coquimbensis shrub at its center with marked fruits underneath it; a shelter is also visible in one of the corners of the arena. C. M. coquimbensis fruits showing the fishing line and flagging tape.
Fig 2.
Relationship between fruit mass and the probability of a fruit being harvested for consumption by A. olivaceus, P. darwini and O. degus.
The results were modeled using a mixed effects logistic regression.
Fig 3.
Relationship between fruit mass and the probability of a fruit that was harvested for consumption to be transported to a hoarding site by A. olivaceus, P. darwini and O. degus.
The results were modeled using a mixed effects logistic regression.
Fig 4.
Frequency distributions of fruit sizes hoarded by A. A. olivaceus, B. P. darwini and C. O. degus.
The dashed vertical lines indicate the mean size of fruits offered to each species during the trials (see text). Vertical marks along the seed mass axis represent unique documented hoarded fruits. We included a non-parametric smoothing spline fit (dark blue line) to the empirical distance distribution together with bootstrapped estimates (grey lines) to allow comparisons across plots.

A. Fruit mass of fruits hoarded by A. olivaceus, P. darwini and O. degus. The graph shows means ± 1SE estimated using a mixed effects model. B. Boxplot of the percentage of seed mass consumed in predated seeds by A. olivaceus, P. darwini and O. degus.
