  2. Forest pathology - Wikipedia

    en.wikipedia.org/wiki/Forest_pathology

    Forest pathology is the research of both biotic and abiotic maladies affecting the health of a forest ecosystem, primarily fungal pathogens and their insect vectors. [1] [2] It is a subfield of forestry and plant pathology.

  3. 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 ...

  4. 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).

  5. Ecological crisis - Wikipedia

    en.wikipedia.org/wiki/Ecological_crisis

    Degradation of an abiotic ecological factor (for example, increase of temperature, less significant rainfalls) Increased pressures from predation; Rise in the number of individuals (i.e. overpopulation) The evolutionary theory of punctuated equilibrium sees infrequent ecological crises as a potential driver of rapid evolution.

  6. 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 ]

  7. Realized niche width - Wikipedia

    en.wikipedia.org/wiki/Realized_niche_width

    Again, these changes are important in understanding the effects of invasive species in a new habitat. The ability of a new species to change an environments abiotic and biotic factors can make a previously habitable environment for a species uninhabitable. The extinction of this species can further change the biotic factors of an environment.

  9. Invasibility - Wikipedia

    en.wikipedia.org/wiki/Invasibility

    There are many factors, abiotic and biotic, that can raise or lower a habitat's invasibility, such as stress, disturbance, nutrient levels, climate, and pre-existing native species. Typically invasive species favor areas that are nutrient-rich, have few environmental stresses , and high levels of disturbances .
