Figure 4: Dietary niche
partitioning within and among 5 species of Campylomormyrus and
one species of its sister genus Gnathomemus by nMDS of RRA-based
Bray–Curtis dissimilarity indices of samples on the order level (adonis
F = 3.04, R2 = 0.243, p ≤ .001). The symbols represent
the species and the colors represent snout length. The shaded convex
hulls indicate short vs. long EOD. The stress level of 0.133 is under
the cut-off value of 0.2 as recommended by Clarke (1993) to indicate an
interpretable ordination.
