What is Biodiversity?01:19

What is Biodiversity?

33.9K
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:

The Eukaryotic Promoter Region02:40

The Eukaryotic Promoter Region

19.0K
The eukaryotic promoter region is a segment of DNA located upstream of a gene. It contains an RNA polymerase binding site, a transcription start site, and several cis-regulatory sequences.  The proximal promoter region is located in the vicinity of the gene and has cis-regulatory sequences and the core promoter. The core promoter is the binding site for RNA polymerase and is usually located between -35 and +35 nucleotides from the transcription start site. The distal promoter regions are...

Area of Science:

  • Theoretical ecology
  • Ecosystem dynamics
  • Biodiversity research

Background:

  • Explaining biodiversity is central to theoretical ecology.
  • The competitive exclusion principle (CEP) posits that species competing for identical resources cannot coexist.
  • The paradox of the plankton highlights the conflict between CEP and observed biodiversity.

Purpose of the Study:

  • To review proposed mechanisms for promoting biodiversity.
  • To focus on mechanisms that alleviate constraints imposed by the CEP.
  • To examine how biodiversity is maintained despite resource limitations.

Main Methods:

  • Literature review of ecological theories.
  • Analysis of mechanisms challenging or circumventing the CEP.
  • Synthesis of studies on biodiversity maintenance.

Main Results:

  • Identified various mechanisms that promote species coexistence.
  • Highlighted strategies that challenge the CEP in steady-state, well-mixed systems.
  • Detailed approaches that circumvent CEP limitations via contextual differences.

Conclusions:

  • Ecological mechanisms effectively promote biodiversity by mitigating CEP.
  • Understanding these mechanisms is crucial for theoretical ecology and conservation.
  • Biodiversity can be maintained through diverse strategies that overcome competitive exclusion.
