| Term | Definition |
| Succession | The process by which the species composition of a community changes over time. |
| Seral stage | Each stage of community change during the process of succession. |
| Pioneer species | The earliest species to arrive at a site. |
| Climax community | The final seral stage in the process of succession. |
| Chronosequence | A sequence of communities that exist over time at a given location. |
| Primary succession | The development of communities in habitats that are initially devoid of plants and organic soil, such as sand dunes, lava flows, and bare rock. |
| Secondary succession | The development of communities in habitats that have been disturbed and contain no plants but still contain an organic soil. |
| Facilitation | A mechanism of succession in which the presence of one species increases the probability that a second species can become established. |
| Inhibition | A mechanism of succession in which one species decreases the probability that a second species will become established. |
| Priority effect | When the arrival of one species at a site affects the subsequent colonization of other species. |
| Tolerance | A mechanism of succession in which the probability that a species can become established depends on its dispersal ability and its ability to persist under the physical conditions of the environment. |
| Transient climax community | A climax community that is not persistent. |
| Fire-maintained climax community | A successional stage that persists as the final seral stage due to periodic fires. |
| Grazer-maintained climax community | When a successional stage persists as a final seral stage due to intense grazing. |
