Threats to Biodiversity01:50

Threats to Biodiversity

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...
What is Biodiversity?01:19

What is Biodiversity?

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.
Biodiversity and Human Values01:24

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.
What is Conservation Biology?01:57

What is Conservation Biology?

Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.
Conservation of Declining Populations02:07

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.
Sustainable Development01:43

Sustainable Development

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Area of Science:

  • Conservation science
  • Environmental policy
  • Biodiversity monitoring

Background:

  • Effective global policy requires robust predictions of policy impacts on biodiversity.
  • Reliable indicators are crucial for measuring progress towards conservation goals.
  • The Convention on Biological Diversity (CBD) sets targets for global conservation efforts.

Purpose of the Study:

  • To present a framework for using biodiversity indicators predictively to inform global policy choices.
  • To illustrate this framework with case studies projecting policy impacts on biodiversity trends and indicators.
  • To assess the utility of indicators in differentiating policy impacts.

Main Methods:

  • Developing a predictive framework for biodiversity indicators.
  • Applying the framework to two case studies based on CBD targets.
  • Case Study 1: Protected area policies for African mammals using the Red List Index.
  • Case Study 2: Bottom trawling policies using the Living Planet Index.

Main Results:

  • The Red List Index effectively differentiated impacts of protected area policies on African mammals.
  • The Living Planet Index showed counter-intuitive behavior in the bottom trawling case study due to indicator composition and trophic interactions.
  • The framework demonstrated the potential for predictive indicators to inform policy decisions.

Conclusions:

  • Predictive models and biodiversity indicators are essential for credible trend tracking and policy informing.
  • Further research is needed to refine the use of indicators for policy relevance.
  • Testable predictions linking global policy to biodiversity impacts are necessary for effective conservation change.
