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.
Cyclic succession is a pattern of vegetation change in which in a small number of species tend to replace each other over time in the absence of large-scale disturbance. Observations of cyclic replacement have provided evidence against traditional Clementsian views of an end-state climax community with stable species compositions.
The distinction between spatial and spatio-temporal patterns in nature is not clear-cut because a static, invariable pattern will never occur in the strict sense. Even rock formations will slowly change on a time-scale of tens of millions of years, therefore the distinction lies in the time scale of change in relation to human experience.
Patterns of distribution change depending on the scale at which they are viewed, from the arrangement of individuals within a small family unit, to patterns within a population, or the distribution of the entire species as a whole (range).
An idealized pattern of age-graded change. The expected pattern is a u- or v-shaped curve (see figure to the right). Nonprestigious age-graded linguistic features tend to peak during adolescence “when peer group pressure not to conform to society’s norms is greatest” (Holmes 1992:184). [4]
La Niña is a natural climate pattern marked by cooler-than-average seawater in the central and eastern Pacific Ocean. When the water cools at least 0.9 degree Fahrenheit below average for three ...
Gersick examined models of change in six domains - developmental patterns of adults, groups and organizations, the history of science, physical science, and biological evolution - and found evidence for punctuated equilibria (as opposed to steady, incremental change) across those disparate systems.

Social change may not refer to the notion of social progress or sociocultural evolution, the philosophical idea that society moves forward by evolutionary means.It may refer to a paradigmatic change in the socio-economic structure, for instance the transition from feudalism to capitalism, or hypothetical future transition to some form of post-capitalism.
