Figure 1 – Frequency of occurrence network showing the families
ingested by black wheatear males and females. On the bottom, animal
orders are in grey and plant orders in green. Red interactions indicate
orders consumed in significantly different proportions by both sexes, as
revealed by univariate tests. Only the names of the most frequent
families (more than 10% frequency) are shown.
Figure 2 – Rarefaction curves showing the observed (full line) and
estimated (dashed line) richness, until double the reference sample
size, and respective 84% confidence interval (a proxy for α = 0.05) by
sample coverage.
