abstract: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.
If cells were actively proliferating, that is you had a population of cells that are actively proliferating, they would be going through continuous rounds of the cell cycle.
The rising tree population could disrupt the natural processes that cycle snow and energy through the region and increase the amount of carbon it stores, according to the researchers.
