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.

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...

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.

Epiphytes, Parasites, and Carnivores

Epiphytes, Parasites, and Carnivores

Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the biosynthesis of the...

Ecological Disturbance

Ecological Disturbance

An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.Ecological disturbances can be caused by an event as small as the trampling of underbrush to an incident as wide-ranging as a forest...

Summary

Amazon forests may be more resilient to climate change than models suggest. Satellite data revealed a photosynthetic green-up during a 2005 drought, contrary to climate-carbon cycle model predictions.

Area of Science:

Climate science
Ecology
Remote sensing

Background:

Coupled climate-carbon cycle models indicate Amazon forests are susceptible to drought.
Past research suggests vulnerability to both short-term and long-term droughts.

Purpose of the Study:

To investigate Amazon forest response to drought using satellite observations.
To compare observed forest behavior with model predictions.

Main Methods:

Analysis of satellite data to assess photosynthetic activity in Amazon forests.
Comparison of observed green-up during a 2005 drought with model simulations.

Main Results:

Satellite observations showed a large-scale photosynthetic green-up in intact Amazon evergreen forests during a 2005 drought.
This observed green-up contrasts with model predictions of drought vulnerability.

Conclusions:

Amazon forests may exhibit greater resilience to climate change-induced droughts than ecosystem models currently assume.
Despite threats from deforestation and fire, intact forests show a capacity to recover and photosynthesize during drought events.
