Pioneer organism : ウィキペディア英語版 | Pioneer organism
A pioneer organism—also called a disaster taxon—is an organism that populates a region after a (short-term) natural disaster, mass extinction, or any other event that kills off most life in that area. ==Natural disaster== After a natural disaster, common pioneer organisms include lichens and algae. Mosses usually follow lichens in colonization, but cannot serve as pioneer organisms. Pioneer organisms modify their environment and establish conditions that accommodate other organisms. In some circumstances, other organisms can be considered pioneer organisms. Birds are usually the first to inhabit newly created islands, and seeds, such as the coconut, may also be the first arrivals on barren soil.
