Persistence and size of seasonal populations on a consumer–resource relationship depends on the allocation strategy toward life-history functions

Abstract The long-term ecological dynamics of a population inhabiting a seasonal environment is analyzed using a semi-discrete or impulsive system to represent the consumer–resource interaction. The resource corresponds to an incoming energy flow for consumers that is allocated to reproduction as we...
