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 ...
Thus, the nature of species interactions may shift with environmental conditions. Facilitation has a greater effect on plant interactions under environmental stress than competition. [9] Another example is the positive effects of facilitation on desert plants that face the effects of rising aridification.
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.
A plant's first line of defense against abiotic stress is in its roots. If the soil holding the plant is healthy and biologically diverse, the plant will have a higher chance of surviving stressful conditions. [10] The plant responses to stress are dependent on the tissue or organ affected by the stress. [8]
Biotic interactions can vary in intensity (strength of interaction), and frequency (number of interactions in a given time). [ 31 ] [ 32 ] There are direct interactions when there is a physical contact between individuals or indirect interactions when there is no physical contact, that is, the interaction occurs with a resource, ecological ...
Ecophysiology (from Greek οἶκος, oikos, "house(hold)"; φύσις, physis, "nature, origin"; and -λογία, -logia), environmental physiology or physiological ecology is a biological discipline that studies the response of an organism's physiology to environmental conditions.
2. an epidemic of stress, overwork, waste and indebtedness caused by dogged pursuit of the Australian dream. 3. an unsustainable addiction to economic growth. The traditional Western environmentally unfriendly high consumption life-style: a play on the words affluence and influenza cf. froogle, freegan.
Often the plant can modulate its diversity based on the benefits in terms of growth and health, such as with plant growth-promoting rhizobacteria. [46] Nevertheless, a large number of nutrients issued by the plant can be of interest to pathogenic organisms, which can take advantage of plant products for their survival in the rhizosphere.
