a negative trendP <0.0001
As expected, a negative trend between both variables is evident in the two groups ( Fig. 4b ), with individual seed mass decreasing linearly with increasing fruit seediness ( F = 126.0, P <0.0001, d.f. = 3, 87).

highly significantP <0.003
The differences in relative frequencies of the seven colors are highly significant (χ 2 = 14.16, P <0.003, d.f. = 6).
Within-family and within-genus contrasts between megafaunal and non-megafaunal groups of species indicate a marked difference in fruit diameter and fruit mass but less so for individual seed mass, with a significant trend for megafaunal fruits to have larger seeds and seediness.
