open access: yesOikos, EarlyView.
Resource quantity in the environment often changes over time and influences the nutritional status of hosts that may encounter parasites. If resource availability significantly alters both infection success and within‐host growth of a parasite, fluctuations in resources may underlie the seasonal disease outbreaks that have been observed for some ...
