Bubble chart showing the relationships between PLS X’s component, representing the gut and lung nematode community, and the PLS Y’s component representing the health status in eleven male chamois from the Catalan Pyrenees, northeast Spain. The nematode community block was mainly represented by gastrointestinal and lung nematode richness and by gastrointestinal nematode intensity of infection, whereas the health block was represented by glutathione peroxidase (GPX) and paraoxonase-1 (PON1) concentrations, and by body condition. The initial set of variables representing each block is provided in Table 3. Bubble size indicates total (gut and lung) nematode richness ranging from 0 to 19 nematode species. Bubble colour indicates nematode burden. Chamois silhouettes represent a male chamois with low parasite load and hence in good condition and with a good antioxidant response (top left) and a highly parasitized male chamois in poorer condition and lower antioxidant response (bottom right)
