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 ...
A pioneer organism, also called a disaster taxon, is an organism that colonizes a previously empty area first, or one that repopulates vacant niches after a natural disaster, mass extinction or any other catastrophic event that wipes out most life of the prior biome. [1]
An example of pioneer species, in forests of northeastern North America are Betula papyrifera (White birch) and Prunus serotina (Black cherry), that are particularly well-adapted to exploit large gaps in forest canopies, but are intolerant of shade and are eventually replaced by other shade-tolerant species in the absence of disturbances that ...
This tree is a fast-growing species found in previously disturbed areas and on forest margins. It is a pioneer species that can grow on poor soil and can be used to regenerate forest areas by providing shade and protection to saplings of forest hardwoods. T. orientale is nitrogen fixing and can thereby improve soil fertility for other plant ...
It is a pioneer species in rough terrain. [4] It likely colonized wide areas of the Arctic as ice sheets receded. [ 10 ] This species dominates several Arctic habitat types, being the first plant to take hold in the scoured substrate and becoming the most abundant species in the area.
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 ...
The species S. bouchardi is known to have been a pioneer species that colonised areas denuded of brachiopods in the northwestern Tethyan region. [118] Ostracods also suffered a major diversity loss, [ 119 ] [ 120 ] with almost all ostracod clades’ distributions during the time interval corresponding to the serpentinum zone shifting towards ...
