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...

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.

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.

Dimensions of Health and Illness

Dimensions of Health and Illness

The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.

The Soil Ecosystem

The Soil Ecosystem

Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

Whole Body Regeneration

Whole Body Regeneration

Regeneration is the process of restoring injured or lost tissues, organs, or body parts. While simpler organisms generally show greater ability to regenerate their whole body, few complex animals show similarly exceptional regeneration. For example, planarian flatworms have a unique regenerative potential making them a popular study organism among biologists to understand the mechanisms of whole body regeneration. Other organisms, such as hydra, also show extreme regeneration potential;...

Summary

This summary is machine-generated.

Habitat fragmentation threatens wildlife populations. Reconnecting nature through corridors, overpasses, and tunnels allows species to move, mitigating genetic and demographic issues in isolated populations.

Area of Science:

Ecology
Conservation Biology
Wildlife Management

Background:

Habitat fragmentation isolates wildlife populations, reducing their viability.
Human activities create barriers like roads and fences, hindering animal movement.
The UN's 'decade of restoration' highlights the need for ecological connectivity.

Purpose of the Study:

To review and assess the efficacy of actions aimed at reconnecting fragmented habitats.
To provide evidence supporting the importance of facilitating wildlife movement.
To inform conservation strategies for the 'decade of restoration'.

Main Methods:

Review of small-scale experiments and large-scale conservation programs.
Analysis of data on species movement across artificial barriers.
Evaluation of the impact of habitat corridors and connectivity structures.

Main Results:

Evidence shows that even simple connections, like highway overpasses, facilitate wildlife movement.
Facilitated movement can alleviate genetic and demographic problems in small, isolated populations.
Species demonstrate movement when opportunities are provided, indicating successful reconnection.

Conclusions:

Reconnecting nature is crucial for mitigating the negative impacts of habitat fragmentation.
Implementing connectivity measures is essential for successful habitat restoration initiatives.
Facilitating species movement is a key indicator of success in conservation efforts.
