A pioneer species is a species which colonizes previously uncolonized land, usually leading to ecological succession. Since uncolonised land usually has thin, poor quality soils with few nutrients, pioneer species are typically very hardy plants, with adaptions such as long roots, root nodes containing nitrogen fixing bacteria, and leaves that reduce transpiration. For other uses, see Species (disambiguation). ... Secondary succession: trees are colonizing uncultivated fields and meadows. ... Nitrogen fixation is the process by which nitrogen is taken from its relatively inert molecular form (N2) in the atmosphere and converted into nitrogen compounds (such as, notably, ammonia, nitrate and nitrogen dioxide)[1] useful for other chemical processes. ...

Transpiration is the evaporation of excess water from aerial parts and of plants, especially leaves but also stems, flowers and fruits. ...

Pioneer species are often grasses such as marram grass, which grows on sand dunes. Species Ammophila arenaria Ammophila breviligulata Marram Grass or Beach Grass is a genus of two species of grass growing almost exclusively on coastal sand dunes, where rhizomes on its extensive root system allow it to survive in a very harsh and windswept ecosystem. ... This article is about the sand formations, for other meanings see Dune (disambiguation) Mesquite Flat Dunes in Death Valley National Park In physical geography, a dune is a hill of sand built by eolian (wind-related) processes. ...

The plants will be specially adapted to the extremes that may be experienced, and once they have modified the environment may be out-competed by less specific plants, eventually leading to a climax community. Examples of the plants and organisms that colonise such areas are: The term climax community, also described as a climatic climax community, is a largely obsolete ecological term for a biological community of plants and animals which, through the process of ecological succession - the development of vegetation in an area over time - has reached a steady state. ...

Pioneer species in secondary succession

Pioneer species can also be found in secondary succession (an established ecosystem being reduced by an event such as a forest fire of a clearing), colonizing newly created open spaces quickly. Common examples from a coniferous forest include: I love sum 41!!!!!!!!!!

Pioneering fauna

Pioneering fauna are not responsible for initial colonisation of an area, but can be seen to be colonising an area only flora and fungi previously inhabited, leading the way for others. A good example of this is the Roe Deer. Fauna is a collective term for animal life of any particular region or time. ...
