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.
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 ...
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 .
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.
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.

The main driving factor of the oxygen cycle is photosynthesis, which is responsible for the modern Earth's atmospheric composition and life. The phosphorus cycle is the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. The atmosphere does not play a significant role in the movements of phosphorus, because phosphorus ...
