Threats to Biodiversity

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?

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.

Ecological Disturbance

Ecological Disturbance

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.

What is Conservation Biology?

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.

Keystone Species

Keystone Species

Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a...

Summary

Habitat destruction causes biodiversity loss, leading to an ecosystem service debt. This debt can result in significant carbon emissions from remaining ecosystems due to plant species loss.

Area of Science:

Ecology
Environmental Science
Conservation Biology

Background:

Habitat destruction is a primary driver of global biodiversity loss.
Ecosystem functioning and the services they provide are intrinsically linked to biodiversity.
Biodiversity loss can lead to an 'ecosystem service debt,' a delayed decline in human benefits from nature.

Purpose of the Study:

To develop a method for quantifying ecosystem service debts.
To estimate the impact of habitat destruction on carbon storage via extinction debt.
To explore the global implications of diffuse biodiversity loss on ecosystem services.

Main Methods:

Developed a novel approach to quantify ecosystem service debts.
Modeled the indirect effects of habitat destruction on carbon storage.
Estimated potential carbon emissions resulting from plant species loss in ecosystem fragments.

Main Results:

An estimated 2-21 Petagrams (Pg) of Carbon (C) could be emitted globally due to plant species loss from habitat destruction.
Significant uncertainties exist regarding the extent of species loss, its impact on ecosystem function, and effects on soil carbon.
Biodiversity-dependent ecosystem service debts can be substantial globally, even if locally minor, when spread across large areas.

Conclusions:

Conserving the quality (biodiversity) of natural ecosystems is as crucial as conserving their quantity (area).
Addressing habitat destruction is vital to mitigate ecosystem service debts and ensure sustainable benefits.
The study highlights the interconnectedness of biodiversity, ecosystem function, and climate regulation.
