List of plant species and traits

Table S1. Summary of fruit display traits from plant species in a subtropical Andean montane forest of NW Argentina (Southern Yungas). Fruit consumption is a relative frequency of fruit consumption for each plant species by the community of fruit-eating birds (see Methods); Nc (not consumption) indicates fruit species that are not usually eaten by birds , while a hyphen indicates species eaten by birds but without data in our databases. Fruit size is the mean fresh-fruit mass expressed in grams. Fruit colour type is described as it is perceived by humans (i.e., related to hue). Fruit chromatic contrast (ΔS) is expressed in unities of just noticeable difference (JND) between the fruit and the corresponding leaves of the species (background) (see Methods). Fruit exposure has two categories: Exposed (pendulums, erect and terminals) and Unexposed (sessile fruits and fruits that are not exposed away from the contiguous foliage). Fruit aggregation expresses the mean number of fruit in discrete and differentiable groups. Fruit crop size is the mean number of fruits of each plant species, classified into five categories: 1 (1-10 fruits), 2 (11-100), 3 (101-1000), 4 (1001-10000) and 5 ( >10000). See Methods for details. Plant systematics follows Instituto de Botánica Darwinion (2015).
