Many species exhibit population cycles with peaks at regular intervals, such as peaks in population size that occur every 6 years. Explain why it is not likely that environmental variation is the underlying cause of these regular cycles. As part of your explanation, include a description of expected differences between changes in population size due to environmental variation and changes in population size due to density-dependent population regulation.
