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.

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...

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.

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...

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.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

Area of Science:

Conservation biology
Ecology
Risk assessment

Background:

Current conservation prioritisation focuses on threatened species.
Proactive approaches forecasting future extinction risk are needed.
Existing forecasting methods vary in timescale and approach.

Purpose of the Study:

To develop a framework integrating extinction risk assessment across multiple timescales.
To outline tradeoffs between short- and long-term extinction prevention.
To facilitate decision-theoretic conservation prioritisation considering various time horizons.

Main Methods:

Development of an integrated extinction risk assessment framework.
Analysis of Population Viability Analysis (PVA), Early Warning Systems, and Over-the-Horizon (OTH) methods.
Integration of decision theory for conservation prioritisation.

Main Results:

The framework integrates extinction risk across different timescales.
Tradeoffs between short- and long-term conservation goals are identified.
The framework supports decision-theoretic prioritisation for varied time horizons.

Conclusions:

Forecasting extinction risk for unthreatened species is a valuable complementary conservation strategy.
Considering extended timescales for extinction risk offers a future-proof conservation planning approach.
This proactive strategy may prevent more extinctions than focusing solely on currently threatened species.
