Select host trait hypotheses for effects of resource provisioning on infection with microparasites, helminths and ectoparasites

Host trait Effect on microparasites Effect on helminths Effect on ectoparasites
Broad diet diversity ↑↑ Larger host densities increase contact, more exposure through food, malnutrition could increase host susceptibility ↓↓ Less exposure by switching to parasite‐free food, weaker effect of high host density Potential for higher density to increase transmission, weak effects on food exposure and susceptibility
Omnivory ↑↑ Larger host densities increase contact, more exposure through food, malnutrition could increase host susceptibility ↓↓ Less exposure by switching to parasite‐free food, weaker effect of high host density Potential for higher density to increase transmission, weak effects on food exposure and susceptibility
Fast pace of life ↑↓ Stronger fecundity response benefits host density, but improved adaptive immunity promotes recovery Weak effects of reproductive benefit, but enhanced adaptive immune defence Potential for higher density to increase transmission, but weak effects of stronger immunity
Large home range ↑↑ Contraction of home range promotes greater aggregation and contact rates Greater contact with infectious stages, but weak effect on complex life cycle parasites Dense aggregations promote close contact and free‐living exposure
Migratory ↑↑ Loss of migratory escape or culling, greater aggregation and contact rates Greater contact with infectious stages, but weak effect on complex life cycle parasites Loss of migratory escape or culling, greater aggregation and contact rates
