Explain what disclimax is and how some ecosystems are maintained in a state of disclimax. Pioneer species colonize site following disturbance. Pioneer species tend to change the environment favoring the growth of other species that could not have colonized the same site earlier. The text definition is misleading. Pioneer plants, such as lichens and mosses, become established on the bare mineral substrate from spores or seeds that are blown, washed, or carried in by animals.
Volcanic eruption Following the eruption, there is no life in the blast zone.
Eventually, however, pioneer species of plants do establish themselves, beginning the course of succession. Secondary succession is the reconstruction of an ecosystem following a disturbance that damages or removes all or part of the previous community, but leaves the SOIL intact. Faster than primary succession. Succession results in the transition of the original pioneer species to climax community. Pioneer species become established from seeds, spores or plant parts surviving in the soil or from vegetation in surrounding undisturbed areas.
