The relationship between biotic stress and plant yield affects economic decisions as well as practical development. The impact of biotic injury on crop yield impacts population dynamics, plant-stressor coevolution, and ecosystem nutrient cycling. [3] Biotic stress also impacts horticultural plant health and natural habitats ecology. It also has ...
Plant stress research looks at the response of plants to limitations and excesses of the main abiotic factors (light, temperature, water and nutrients), and of other stress factors that are important in particular situations (e.g. pests, pathogens, or pollutants). Plant stress measurement usually focuses on taking measurements from living plants.
Epiphytes (plants growing on other plants, usually trees) have a commensal relationship with their host plant because the epiphyte benefits in some way (e.g., by escaping competition with terrestrial plants or by gaining greater access to sunlight) while the host plant is apparently unaffected.
An example of ecological stability . In ecology, an ecosystem is said to possess ecological stability (or equilibrium) if it is capable of returning to its equilibrium state after a perturbation (a capacity known as resilience) or does not experience unexpected large changes in its characteristics across time.

Injury in plants is damage caused by other organisms or by the non-living (abiotic) environment to plants. Animals that commonly cause injury to plants include insects, mites, nematodes, and herbivorous mammals; damage may also be caused by plant pathogens including fungi, bacteria, and viruses. Abiotic factors that can damage plants include ...
Floristic Quality Assessment (FQA) is a tool used in the United States to assess an area's ecological integrity based on its plant species composition. [1] Floristic Quality Assessment was originally developed in order to assess the likelihood that impacts to an area "would be irreversible or irretrievable...to make standard comparisons among various open land areas, to set conservation ...
In the case of Arabidopsis, [5] since polyamines perform essential roles for growth in all organisms, and most polyamine biosynthetic genes are present in at least two copies in plants, break-out of single gene mutants can cause critical stress in plant. For example, Arabidopsis showed much lower activity in seed development when a specific ...
Negative plant–soil feedback is thought to be an important factor in helping plants to coexist. If a plant is over-abundant, then soil pathogens and other negative factors will become common, hurting its growth. [2] Similarly, if a plant becomes overly rare, then so too will its soil pathogens and other negative factors, helping its growth. [2]
