  2. Forest pathology - Wikipedia

    en.wikipedia.org/wiki/Forest_pathology

    Higher wind speeds are necessary to damage healthier trees. Fire, whether caused by humans or lightning, and related abiotic factors also affect the health of forest. The effects of man often alter a forest's predisposition to damage from both abiotic and biotic effects. For example, soil properties may be altered by heavy machinery.

  3. 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.

  4. Forest ecology - Wikipedia

    en.wikipedia.org/wiki/Forest_ecology

    Trees growing in arid and/or cold environments do so especially slowly. Thus, tree trunks and branches can remain on the forest floor for long periods, affecting such things as wildlife habitat, fire behaviour, and tree regeneration processes. Some trees leave behind eerie skeletons after death.

  5. 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 ...

  6. Abiotic stress - Wikipedia

    en.wikipedia.org/wiki/Abiotic_stress

    Abiotic stress is the negative impact of non-living factors on the living organisms in a specific environment. [1] The non-living variable must influence the environment beyond its normal range of variation to adversely affect the population performance or individual physiology of the organism in a significant way.

  7. 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.

  8. Forest dynamics - Wikipedia

    en.wikipedia.org/wiki/Forest_dynamics

    Forest disturbances are events that cause change in the structure and composition of a forest ecosystem, beyond the growth and death of individual organisms. Disturbances can vary in frequency and intensity, and include natural disasters such as fire, landslides, wind, volcanic eruptions, rare meteor impacts, outbreaks of insects, fungi, and other pathogens, animal-caused effects such as ...

  9. Competition (biology) - Wikipedia

    en.wikipedia.org/wiki/Competition_(biology)

    Competition is one of many interacting biotic and abiotic factors that affect community structure, species diversity, and population dynamics (shifts in a population over time). [3] There are three major mechanisms of competition: interference, exploitation, and apparent competition (in order from most direct to least direct).
