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 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.

Biodiversity and Human Values

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.

Conservation of Declining Populations

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.

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Habitat Fragmentation

Habitat Fragmentation

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.

Area of Science:

Ecology
Conservation Biology
Biodiversity Science

Background:

The planet is experiencing a significant biodiversity crisis.
Simultaneously, there is an unprecedented increase in the availability of global biodiversity data.

Purpose of the Study:

To explore the integration of biodiversity modeling and conservation science.
To inform conservation actions using new datasets and modeling approaches.

Main Methods:

Reviewing new developments in biodiversity modeling.
Highlighting advancements in conservation science.
Examining early examples of integrating these fields.

Main Results:

Vast datasets (e.g., species distributions, traits, phylogenies, interaction networks) offer insights into biodiversity change.
Integration of biodiversity modeling and conservation science is necessary but currently limited.
Early examples show promise for synthesizing these fields.

Conclusions:

A synthesis of biodiversity modeling and conservation science is needed.
This integration will improve our understanding and anticipation of biodiversity change.
Informed conservation decisions require a fuller awareness of the biodiversity at stake.
