  2. Secondary succession - Wikipedia

    en.wikipedia.org/wiki/Secondary_succession

    Secondary succession is the secondary ecological succession of a plant's life. As opposed to the first, primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting ...

  3. Boreal ecosystem - Wikipedia

    en.wikipedia.org/wiki/Boreal_ecosystem

    Success and succession happen in tandem in boreal forests. Primary succession, while part of the original landscape formation, is not vital like secondary succession. [10] Secondary succession consists of varied events: wildfires, flooding, mudslides and even excessive insect foraging act in this progression and cycle of boreal forests. [10]

  4. Ecological succession - Wikipedia

    en.wikipedia.org/wiki/Ecological_succession

    Particularly common types of secondary succession include responses to natural disturbances such as fire, flood, and severe winds, and to human-caused disturbances such as logging and agriculture. In secondary succession, the soils and organisms need to be left unharmed so there is a way for the new material to rebuild. [9]

  5. Ecosystem - Wikipedia

    The remainder is consumed by animals while still alive and enters the plant-based trophic system. After plants and animals die, the organic matter contained in them enters the detritus-based trophic system. [15] Ecosystem respiration is the sum of respiration by all living organisms (plants, animals, and decomposers) in the ecosystem. [16]

  6. Tundra of North America - Wikipedia

    en.wikipedia.org/wiki/Tundra_of_North_America

    Animal species that are endangered in the tundra include the Arctic fox, caribou, and polar bears. These animals have been endangered due to overhunting, an infestation of disease, loss of diet and habitat due to climate change, and human destructive activities, such as searches for natural gas and oil, mining, and road building. [10]

  7. Climax community - Wikipedia

    en.wikipedia.org/wiki/Climax_community

    In scientific ecology, climax community or climatic climax community is a historic term for a community of plants, animals, and fungi which, through the process of ecological succession in the development of vegetation in an area over time, have reached a steady state. This equilibrium was thought to occur because the climax community is ...

  8. Arctic ecology - Wikipedia

    en.wikipedia.org/wiki/Arctic_ecology

    Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66° 33’N). [1] This region is characterized by two biomes: taiga (or boreal forest) and tundra. [2]

  9. Facilitation cascade - Wikipedia

    en.wikipedia.org/wiki/Facilitation_cascade

    The primary and secondary foundation species that make up a facilitation cascade can occur in one of two spatial configurations. [40] First are nested configurations in which the two foundation species are found intermixed or with one facilitator living on another, as in a mangrove pneumatophore providing a surface for oyster colonization.
