Nonlethal Parasite Infections Can Lead to a Greener World

Mechanistic model framework for testing how effects of parasites on the survival (αS), fecundity (αF), and resource intake (αI) of herbivorous hosts affect the population (biomass) dynamics of parasites, free-living parasite propagules, hosts, and producers. Arrows indicate fluxes between compartments, and rates written next to arrows are per capita of the compartment where the arrow begins. Dashed lines indicate life-cycle transitions for the parasite.

In their recent PNAS paper, YIBS affiliate & EEB Professor Vanessa Ezenwa et.al report on how sublethal parasitic infections can decrease herbivory rates, thus triggering cascades that negatively affect plant communities and surrounding ecology.
