Herbivores' effects on plant diversity vary across environmental changes. Herbivores could increase plant diversity or decrease plant diversity. [1] Loss of plant diversity due to climate change can also affect herbivore and plant community relationships [2] Herbivores are crucial in determining the distribution, abundance, and diversity of plant populations.
Tolerance is the ability of plants to mitigate the negative fitness effects caused by herbivory. It is one of the general plant defense strategies against herbivores , the other being resistance , which is the ability of plants to prevent damage (Strauss and Agrawal 1999).
The effects of climate change on plant biodiversity can be predicted by using various models, for example bioclimatic models. [5] [6] Habitats may change due to climate change. This can cause non-native plants and pests to impact native vegetation diversity. [7] Therefore, the native vegetation may become more vulnerable to damage. [8]
The options for managing sodic soils are minimal; one must select sodicity-tolerant plants or change the soil. The latter is the more difficult process. If changing the soil, one must add calcium to displace the excess exchangeable sodium that causes the disaggregation that blocks water flow. [23]
The concept of combination phenomics comes from the idea that two or more plant stresses have common physiological effects or common traits - which are an indicator of overall plant health. [ 12 ] [ 13 ] [ 14 ] As both biotic and abiotic stresses can result in similar physiological consequence, drought resistant plants can be separated from ...
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]
As plants grow following a disturbance, they change their environment, for example by creating shade, attracting seed dispersers, contributing organic matter to the soil, changing the availability of soil nutrients, creating microhabitats, and buffering temperature and moisture fluctuations.
Plant ecophysiology is concerned largely with two topics: mechanisms (how plants sense and respond to environmental change) and scaling or integration (how the responses to highly variable conditions—for example, gradients from full sunlight to 95% shade within tree canopies—are coordinated with one another), and how their collective effect on plant growth and gas exchange can be ...
