What is Biodiversity?

34.3K
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.

Symbiosis

37.8K
Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Biodiversity and Human Values

17.4K
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.

Ecological Disturbance02:26

Ecological Disturbance

21.2K
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 Niches

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

Area of Science:

  • Ecology
  • Biodiversity research
  • Ecosystem functioning

Background:

  • The value of biodiversity is often linked to its role in sustaining multiple ecosystem functions.
  • It is widely assumed that more functions require greater species diversity.

Purpose of the Study:

  • To investigate the relationship between biodiversity and ecosystem multifunctionality.
  • To challenge the prevailing view that increasing functions necessitates higher biodiversity.

Main Methods:

  • Simulations were used to model the effects of biodiversity on ecosystem functions.
  • Analysis focused on non-additive effects of species on individual functions.

Main Results:

  • The relationship between biodiversity and ecosystem functioning does not change with the number of functions considered.
  • Biodiversity's effect on multifunctionality is equivalent to its average effect on single functions.

Conclusions:

  • Current methods for studying biodiversity-multifunctionality have limitations and pitfalls.
  • Future research should re-evaluate approaches to understanding biodiversity's role in ecosystem functioning.
