Fig. 2 in Differentiation of Trichuris species using a morphometric approach

Fig. 2. Factor map corresponding to adult Trichuris sp. females derived from four different host primate species (Macaca sylvanus, Pan troglodytes, Colobus guereza kikuyensis, Papio ursinus) and the pig (Sus scrofa domestica) from zoos and abattoirs, respectively, in Spain. Samples are projected onto the first (PC1, 61%) and second (PC2, 35%) principal components. Each group is represented by its perimeter. Circles represent the centroid in each community.
