Getting the measure of biodiversity
Nature
|May 23, 2000
Summary
Biological diversity (biodiversity) encompasses all life from genes to ecosystems. While challenging to measure, studying its facets reveals alarming human-driven loss impacting ecosystem functions.
Area of Science:
- Ecology
- Evolutionary Biology
- Conservation Science
Background:
- Biological diversity (biodiversity) is defined as the sum of all biotic variation across genes, species, and ecosystems.
- Measuring the full scope of biodiversity presents significant challenges.
- Understanding the drivers and consequences of biodiversity loss is critical.
Purpose of the Study:
- To explore methods for measuring biodiversity.
- To investigate the ecological and evolutionary factors shaping biodiversity.
- To assess the impact of human activities on biodiversity and ecosystem functioning.
Main Methods:
- Phylogenetic analyses to understand evolutionary relationships.
- Temporal analyses to study changes in biodiversity over time.
- Examination of biodiversity facets to reveal patterns and trends.
Main Results:
- Biodiversity, while not reducible to a single metric, can be studied through specific facets yielding significant discoveries.
- Phylogenetic and temporal analyses illuminate the processes shaping biodiversity.
- Human activities are causing rapid and alarming rates of biodiversity loss.
Conclusions:
- Despite challenges in measurement, studying biodiversity facets offers crucial insights.
- Human-induced biodiversity loss poses a significant threat to ecosystem functioning.
- Current research efforts, though valuable, are insufficient given the scale of unknown diversity and the urgency of conservation needs.

01:19What is Biodiversity?
28.1K
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.

01:50Threats to Biodiversity
21.9K
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...

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.

02:31Habitat Fragmentation
15.8K
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

01:19Methods to Assess Microbial Communities

Microbial communities, comprising bacteria, archaea, and eukaryotic microorganisms, inhabit diverse ecosystems and play crucial roles in environmental and biological processes. Their diversity is defined by three main parameters: species richness (the number of distinct species), species abundance (the relative quantity of each species), and species evenness (how uniformly individual species are distributed in various locations). These factors together shape the structure and ecological balance...
