Balance of Nature |
An environmental myth that states that the natural environment, when not influenced by human activity, will reach a constant status, unchanging over time, referred to as an equilibrium state. |
|
|
Chronic Patchiness |
A situation where ecological succession does not occur. One species may replace another, or an individual of the first species may replace it, but no overall general temporal pattern is established. Characteristic of harsh environments such as deserts. |
|
|
Early-Successional Species |
Species that occur only or primarily during early states of succession. |
|
|
Ecological Restoration |
Restoration of the land and water that utilizes ecologic principals. |
|
|
Ecological Succession |
The process of the development of an ecological community or ecosystem, usually viewed as a series of stages-early, middle, late, mature/climax (& sometimes post-climax). |
|
|
Facilitation |
During succession, one species prepares the way for the next (and may even be necessary for the occurrence of the next). |
|
|
Interference |
During succession, one species prevents the entrance of later successional species into an ecosystem. |
|
|
Late-Successional Species |
Species that occur only or primarily in, or are dominant in, late stages in succession. |
|
|
Nitrogen Fixation |
The process by which atmospheric nitrogen is converted to ammonia, nitrate ion, or amino acids. Microorganisms perform most of the conversion, but a small amount is also converted by lightning. |
|
|
Primary Succession |
The initial establishment and development of an ecosystem. |
|
|
Restoration Ecology |
The field within the science of ecology with the goal to return damaged ecosystems to ones that are functional, sustainable, and more natural. |
|
|
Secondary Ecology |
The reestablishment of an ecosystem where there are remnants of a previous biological community. |
|
|
Successional Stages |
The process of establishment and development of an ecosystem. |
