Ecological processes are often influenced by seasonal variations. These variations may generate complex responses, which can be advantageously analyzed using the concept of nonlinear nonclassical universality. This procedure is illustrated by considering periodic fluctuations in single species harvesting and seasonal changes in the environment carrying capacity. It is shown that the ratio between the perturbation period and the reaction time of the associated autonomous system plays a crucial role in the response, whose spectral components are investigated in detail.
