Question | Answer |
---|---|
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. |
climax state | An ideal, final stage of succession, now known to not exist in nature. Defined as a steady-state stage that would persist indefinitely and have maximum organic matter, maximum storage of chemical elements, and maximum biological diversity. |
early-successional species | Species that occur only or primarily during early stages of succession. |
ecological succession | The process of the development of an ecological community or ecosystem, usually viewed as a series of stages-early, middle, late, mature (or climax) and sometimes postclimax. |
facilitation | During succession, one species prepares the way for the next (and may even be necessary for the occurence of the next). |
interference | During succession, one species prevents the entrance of later successional species into an ecosystem. For example, some grasses produce such dense, thick mats that seeds of trees cannot reach the soil to germinate. |
late-successional species | Species that occur only or primarily in, or are dominant in, late stages of succession. |
life history difference | Difference in the patterns of growth and reproduction of 2 species. Can lead to differences in how they populate an area during succession. |
primary succession | The initial establishment and development of an ecosystem. Can occur after an ecosystem is completely wiped out by a landslide, volcanic eruption, or development. |
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 in some meaning of this word. |
secondary succession | The reestablishment of an ecosystem where there are remnants of a previous biological community, such as after a flood, a fire, or when an agricultural area is no longer in use. |
successional stages | General patterns of succession that can be found in most ecosystems, although the species differ. Usually described primarily in terms of vegitation. |
