What Is Cyclic Population

A population cycle in zoology is a phenomenon where populations rise and fall over a predictable period of time. There are some species where population numbers have reasonably predictable patterns of change although the full reasons for population cycles is one of the major unsolved ecological problems.

What is cyclical population growth?

Many populations, over time, exhibit periods of growth and decline. Cyclic changes in population growth can be caused by seasonal, or other environmental changes, or can be driven by density-dependent processes, such as predation, like the snowshoe hare and lynx example depicted here.

What are the four general types of population fluctuations in nature?

Four general types of population fluctuations in nature are: stable, irruptive, cyclic, and irregular. 2. A stable population fluctuates slightly above and below carrying capacity and is characteristic of many species living under fairly constant environmental conditions.
