  2. Abiotic component - Wikipedia

    en.wikipedia.org/wiki/Abiotic_component

    Humans can make or change abiotic factors in a species' environment. For instance, fertilizers can affect a snail's habitat, or the greenhouse gases which humans utilize can change marine pH levels. Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and ...

  3. Biome - Wikipedia

    en.wikipedia.org/wiki/Biome

    In 1947, the American botanist and climatologist Leslie Holdridge classified climates based on the biological effects of temperature and rainfall on vegetation under the assumption that these two abiotic factors are the largest determinants of the types of vegetation found in a habitat. Holdridge uses the four axes to define 30 so-called ...

  4. Lake ecosystem - Wikipedia

    en.wikipedia.org/wiki/Lake_ecosystem

    Temperature is an important abiotic factor in lentic ecosystems because most of the biota are poikilothermic, where internal body temperatures are defined by the surrounding system. Water can be heated or cooled through radiation at the surface and conduction to or from the air and surrounding substrate. [ 6 ]

  5. Boreal ecosystem - Wikipedia

    en.wikipedia.org/wiki/Boreal_ecosystem

    Boreal forest near Shovel Point in Tettegouche State Park, along the northern shore of Lake Superior in Minnesota.. A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° and 70°N latitude.

  6. 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]

  7. Environmental gradient - Wikipedia

    en.wikipedia.org/wiki/Environmental_gradient

    The abiotic factors that environmental gradients consist of can have a direct ramifications on organismal survival. Generally, organismal distribution is tied to those abiotic factors, but even an environmental gradient of one abiotic factor yields insight into how a species distribution might look.

  8. Species distribution - Wikipedia

    en.wikipedia.org/wiki/Species_distribution

    edaphic factors are abiotic factors regarding soil, such as the coarseness of soil, local geology, soil pH, and aeration; and social factors include land use and water availability. An example of the effects of abiotic factors on species distribution can be seen in drier areas, where most individuals of a species will gather around water ...

  9. Environmental factor - Wikipedia

    en.wikipedia.org/wiki/Environmental_factor

    An environmental factor, ecological factor or eco factor is any factor, abiotic or biotic, that influences living organisms. [1] Abiotic factors include ambient temperature , amount of sunlight , air, soil, water and pH of the water soil in which an organism lives.
