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.

Survival Tree

Survival Tree

Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Global Climate Change

Global Climate Change

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

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.

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Area of Science:

Forest Ecology
Climate Change Science
Remote Sensing

Background:

China's environmental goals include forest protection and expansion.
Climate variability increases drought frequency and severity, impacting forest health.
Limited assessment exists for planted forest drought risk, especially comparing natural and planted types.

Purpose of the Study:

To compare drought resistance and resilience between natural and planted forests in China.
To identify factors contributing to differential drought risk.
To inform forest management strategies under climate change.

Main Methods:

Utilized satellite observations from 2001 to 2020.
Assessed drought resistance and resilience metrics for forest types.
Analyzed changes in these metrics over two decades (2001-2010 vs. 2011-2020).

Main Results:

Planted forests demonstrated significantly lower drought resistance and resilience than natural forests.
Subtropical broad-leaved evergreen and warm temperate deciduous broad-leaved forests were particularly vulnerable.
Planted forests showed increased resistance but decreased resilience from 2001-2010 to 2011-2020.
Lower canopy height and poorer soil nutrients limited resistance; canopy height and drought severity/duration/frequency reduced resilience in planted forests.

Conclusions:

Planted forests face a higher potential risk of drought exposure compared to natural forests.
Management strategies should prioritize natural forest preservation and enhance structural diversity in planted forests.
Adaptation measures are crucial for mitigating drought impacts on planted forests amidst climate change.
