[1] [2] [3] Environmental conditions play a key role in defining the function and geographic distributions of plants. Therefore, when environmental conditions change, this can result in changes to biodiversity. [4] The effects of climate change on plant biodiversity can be predicted by using various models, for example bioclimatic models. [5] [6]
Air is vital for respiration in soil organisms and in plant growth. [13] Both wind and atmospheric pressure play critical roles in soil aeration. [14] In addition, convection and diffusion also influence the rates of soil aeration [13] Soil structure refers to the size, shape and arrangement of solid particles in soil.
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 ...
A tropical plant community on Diego Garcia Rangeland monitoring using Parker 3-step Method, Okanagan Washington 2002. Plant ecology is a subdiscipline of ecology that studies the distribution and abundance of plants, the effects of environmental factors upon the abundance of plants, and the interactions among plants and between plants and other organisms.

Phosphorus (P) is an essential macronutrient required for plant growth and development, but it is present only in limited quantities in most of the world's soil. Plants use P mainly in the form of soluble inorganic phosphates (PO 4 −−− ) but are subject to abiotic stress when there is not enough soluble PO 4 −−− in the soil.
Although environmental gradients are comprised gradually changing and predictable patterns of an abiotic factor, there is strong interplay between both biotic-biotic factors as well as biotic-abiotic factors. For example, species abundance usually changes along environmental gradients in a more or less predictable way.
The major function of JA and its various metabolites is regulating plant responses to abiotic and biotic stresses as well as plant growth and development. [3] Regulated plant growth and development processes include growth inhibition, senescence, tendril coiling, flower development and leaf abscission. JA is also responsible for tuber formation ...
Fertilizers are used to provide crops with additional sources of nutrients, such as nitrogen, phosphorus, and potassium, that promote plant growth and increase crop yields. While they are beneficial for plant growth, they can also disrupt natural nutrient and mineral biogeochemical cycles and pose risks to human and ecological health.
