The term pioneer species is also used to refer to the first species, usually plants, to return to an area after disturbance as part of the process of secondary succession. Disturbances may include floods, tornadoes, forest fires, deforestation, or clearing by other means. [18] Pioneer species tend to be fast-growing, shade-intolerant, and tend ...
Primary succession is the beginning step of ecological succession where species known as pioneer species colonize an uninhabited site, which usually occurs in an environment devoid of vegetation and other organisms. In contrast, secondary succession occurs on substrates that previously supported vegetation before an ecological disturbance. This ...
After a natural disaster, common pioneer organisms include lichens and algae. Mosses usually follow lichens in colonization but cannot serve as pioneer organisms. These common pioneer organisms can have a preference in the temperatures they are in. Lichens are more inclined to be in regions with more rainfall, whereas algae and mosses have a preference of being in regions with more humidity.
Gleason argued that species distributions responded individualistically to environmental factors, and communities were best regarded as artifacts of the juxtaposition of species distributions. Gleason's ideas, first published in 1926, were largely ignored until the late 1950s. Two quotes illustrate the contrasting views of Clements and Gleason.
In a psammosere, the organisms closest to the sea will be pioneer species: [5] halophytes (salt-tolerant species) such as littoral algae and glasswort, with marram grass stabilising the dunes. Progressing inland, many characteristics of the ground change which helps determine the natural succession of the dunes.
Polytrichum strictum is considered an important pioneer species in peatlands, able to tolerate a wide range of environmental conditions and disturbance regimes. [6] It is instrumental in preventing frost heaving in harvested peatlands, and research suggests it can be used in the restoration of unstable peat areas, although little is known about ...
The modern understanding of the plate tectonic cycle predicts that remnants of submerged plates will be found near subduction zones. ... The Pioneer Woman. ... The #1 best way to stop being ...
Many species have a narrow altitudinal and ecological niche, with certain species specializing in specific habitats, such as seasonally inundated habitats, rocky slopes, swamps, natural or man-made clearings, etc. Species in the genus Cecropia are some of the most abundant pioneer tree species in natural tree-fall gaps inside primary forests ...
