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 … See more Olaus Magnus, the Archbishop of Uppsala in central Sweden, identified that species of northern rodents had periodic peaks in population and published two reports on the subject in the middle of the 16th century. See more Each population cycle tends to last as long as a species' life expectancy (i.e. lemmings, rabbits and locusts) See more • Population dynamics See more While the phenomenon is often associated with rodents, it does occur in other species such as the ruffed grouse. There are other species which have … See more There is also an interaction between prey with periodic cycles and predators. As the population expands, there is more food available for predators. As it contracts, there is less food available for predators, putting pressure on their population numbers. See more WebIn the real world, population explosion is usually followed by A continuation of high population levels indefinitely A gradual decrease in population as food supplies dwindle A tremendous increase in genetic diversity A gradual increase in population due to the availability of mates A population crash A population crash
