What is Biodiversity?01:19

What is Biodiversity?

34.0K
Biodiversity describes the variety of living things at multiple organizational levels: genetic, species and ecosystem diversity. Species diversity includes all branches of the evolutionary tree from single-celled prokaryotic organisms, bacteria, and archaea, to the eukaryotic kingdoms: plants; animals; fungi; and protists. To date, there have been about 1.75 million species identified, and new species are discovered every week.

Threats to Biodiversity

27.2K
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...

Biodiversity and Human Values

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

The Soil Ecosystem

25.0K
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

Covalently Linked Protein Regulators02:04

Covalently Linked Protein Regulators

9.7K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....

Area of Science:

  • Ecology
  • Ecosystem Science
  • Food Web Dynamics

Background:

  • Establishing links between biodiversity and ecosystem functioning (BEF) in natural communities is a significant challenge.
  • Existing biodiversity-ecosystem functioning (BEF) studies lack a generalized approach to address trophic complexity.
  • Energy flux dynamics in ecological networks offer a theoretical basis for multitrophic BEF relationships.

Purpose of the Study:

  • To propose a universal tool for understanding ecosystem functioning in multitrophic systems.
  • To apply energy flux quantification in food webs to biodiversity-ecosystem functioning (BEF) research.
  • To foster new discoveries into the drivers of ecosystem functioning in complex ecological systems.

Main Methods:

  • Quantification of energy fluxes within food webs.
  • Analysis of ecological networks to understand trophic complexity.
  • Application of energy flux dynamics to multitrophic biodiversity-ecosystem functioning (BEF) studies.

Main Results:

  • Energy flux quantification provides a powerful and universal tool for BEF research.
  • This approach can be applied across different ecological scales.
  • The application of energy flux in food webs to BEF research is largely unexplored.

Conclusions:

  • Quantifying energy fluxes in food webs is a promising framework for advancing biodiversity-ecosystem functioning (BEF) research.
  • This methodology can elucidate the determinants of ecosystem functioning in complex, multitrophic systems.
  • Further research applying energy flux dynamics is needed to unlock new discoveries in ecosystem science.
