Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Regulation of Transpiration by Stomata

Regulation of Transpiration by Stomata

During photosynthesis, plants acquire the necessary carbon dioxide and release the produced oxygen back into the atmosphere. Openings in the epidermis of plant leaves is the site of this exchange of gasses. A single opening is called a stoma—derived from the Greek word for “mouth.” Stomata open and close in response to a variety of environmental cues.

Responses to Heat and Cold Stress

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Xylem and Transpiration-driven Transport of Resources

Xylem and Transpiration-driven Transport of Resources

The xylem of vascular plants distributes water and dissolved minerals that are taken up by the roots to the rest of the plant. The cells that transport xylem sap are dead upon maturity, and the movement of xylem sap is a passive process.

Regulation of Water Output

Regulation of Water Output

The human body predominantly expels water through the urinary system. On average, an individual generates around 1.5 liters of urine each day. This amount can fluctuate based on how well a person is hydrated, but a critical minimum quantity of urine must be produced to ensure the body's proper functioning. Daily, the kidneys remove 600 to 1200 milliosmoles of dissolved substances, effectively excreting excess minerals and water-soluble toxins such as creatinine, urea, and uric acid from the...

Summary

Vegetation resilience is higher with more water availability but decreases with greater inter-annual precipitation variability. This highlights risks to ecosystems from climate change.

Area of Science:

Ecology
Climate Science
Remote Sensing

Background:

Quantifying ecosystem resilience is crucial for understanding climate change impacts.
Water availability and variability are key factors influencing ecosystem stability.

Purpose of the Study:

To investigate the global relationship between water availability/variability and vegetation resilience.
To assess how different timescales of precipitation variability affect ecosystem resilience.

Main Methods:

Application of empirical and theoretical resilience metrics.
Analysis of remotely-sensed vegetation data.
Global-scale statistical analysis of water variables and resilience.

Main Results:

A positive correlation was found between water availability and vegetation resilience globally.
Increased inter-annual precipitation variability was associated with lower vegetation resilience.
The relationship between intra-annual precipitation variability and resilience was less consistent.

Conclusions:

Vegetation resilience is significantly influenced by water availability and its variability across different timescales.
Projected increases in precipitation variability pose a risk to ecosystem stability and may lead to degradation.
Findings underscore the importance of water dynamics in predicting ecosystem responses to climate change.
