The Carbon Cycle01:14

The Carbon Cycle

43.0K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

The Sulfur Cycle01:22

The Sulfur Cycle

51.6K
Sulfur, an important element in the chemical makeup of proteins, is recycled through the atmosphere and aquatic and terrestrial environments. Found in the atmosphere as sulfur dioxide (SO2), sulfur is released by decaying organisms, weathered rocks, geothermal vents, volcanos, and burning fossil fuels. It is deposited into the ecosystem, cycled through the biotic community, and either released back into the atmosphere as gas or deposited in marine sediment for long-term storage and eventual...

Carbon-dioxide Fixation01:28

Carbon-dioxide Fixation

507
Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

Bioremediation00:46

Bioremediation

21.9K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Threats to Biodiversity01:50

Threats to Biodiversity

26.3K
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...

Softwoods and Hardwoods01:28

Softwoods and Hardwoods

422
Softwoods and hardwoods, derived from different types of trees, are distinguished by their leaf structures and cellular compositions, each serving unique purposes in construction and manufacturing. Softwoods come from cone-bearing trees with needle-like leaves and are predominantly composed of longitudinal cells called tracheids and a smaller proportion of radial cells known as rays. Due to their cellular structure, softwoods are commonly used in construction for structural frames, sheathing,...

Area of Science:

  • Environmental science
  • Forestry
  • Climate change modeling

Background:

  • Forests play a crucial role in carbon sequestration.
  • Accurate projections of future forest carbon fluxes are essential for climate change mitigation strategies.
  • Land management practices significantly influence forest carbon dynamics.

Purpose of the Study:

  • To develop and apply structural dynamic methods for projecting future forest carbon fluxes.
  • To assess the impact of land management changes on both intensive and extensive margins.
  • To evaluate the robustness of these projections under climate change scenarios.

Main Methods:

  • Development of structural dynamic models for forest carbon flux projection.
  • Incorporation of land management variables (intensive and extensive margins).
  • Simulation of forest carbon sequestration under various management and climate scenarios.

Main Results:

  • U.S. forests are projected to remain a significant carbon sink throughout most of the coming century, sequestering an average of 128 Tg C y-1.
  • Constraining forestland and management to current levels reduces average sequestration by 25 to 28 Tg C y-1.
  • Increased demand for forest products leads to intensified management and enhanced carbon sequestration.

Conclusions:

  • Structural dynamic methods provide robust projections of forest carbon fluxes.
  • Land management is a critical factor in determining future forest carbon sequestration capacity.
  • Forests can continue to act as a vital carbon sink, even under climate change, with appropriate management.
