Fig. 4. Relationship of infracommunity abundance of helminths inferred by mixed generalized linear modeling (GLMM) in potamotrygonids of the upper Parana´River. Abundance vs. (a) disc length (DL), (b) gonadal developmental stages (immature = 0, early development = 1, advanced development = 2, mature = 3 and rest = 4), (c) condition factor and (d) sex (males or females) (e) Host species (i.e. Potamotrygon amandae or Potamotrygon falkneri). and collection sites (S1 or S2) are random variables.
