+ | ===== Assignment ===== | ||
+ | |||
+ | Develop and analyze a mathematical model to describe the coupled dynamics of the populations described above. Your model should take into account the interactions among the species in this system. Add whatever components you see fit in order to capture the system' | ||
+ | |||
+ | ===== Questions & Suggestions ===== | ||
+ | |||
+ | * Are the dynamics different from a system where messy feeding releases spores rather than hosts? (You don't have to create a new model for this second system; see Cáceres, Knight and Hall (2009) for a lead) | ||
+ | * How are the dynamics affected if the predator is a specialist instead of a generalist? | ||
