Figure 3. Comparison of the average body size (pronotum width) of female
and male O. babirussa across populations from Malaysia (MY:
Langkawi: n=318, Central Peninsular : n=97) and Singapore (SG:
Pulau Ubin: n=121, CCNR: n=96) to determine the presence of sexual size
dimorphism (SSD). SSD varied across
populations (**=P <0.01, ***=P <0.001,
ns=not significant).
