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 ...
One example of primary succession takes place after a volcano has erupted. The lava flows into the ocean and hardens into new land. The resulting barren land is first colonized by pioneer organisms, like algae, which pave the way for later, less hardy plants, such as hardwood trees, by facilitating pedogenesis, especially through the biotic acceleration of weathering and the addition of ...
Open ocean habitats are found in the deep ocean beyond the edge of the continental shelf. Alternatively, marine habitats can be divided into pelagic and demersal habitats. Pelagic habitats are found near the surface or in the open water column , away from the bottom of the ocean and affected by ocean currents , while demersal habitats are near ...
The discovery of a well-preserved fossil is helping researchers learn more about an iconic Jurassic-period species. The plesiosaur, considered a successful marine predatory ancient species, may ...
Many of the species found living near hydrothermal vents during this expedition had never been seen before. At the time, the presence of thermal springs near the midoceanic ridges was known. Further research uncovered aquatic life in the area, despite the high temperature (around 350–380 °C).

Researchers at the Natural History Museum say the undescribed organisms represent a fraction of the undiscovered species from the deep sea.
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]
