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 Niches

Ecological Niches

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.Multiple species cannot occupy the exact same niche within their habitat. If the niches of two or more species overlap to a large extent, the competitive exclusion principle dictates that one species will outcompete the other, forcing it to...

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.

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.Ecological disturbances can be caused by an event as small as the trampling of underbrush to an incident as wide-ranging as a forest...

Ecological Succession

Ecological Succession

Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...

Ecological Niche

Ecological Niche

Microorganisms occupy diverse habitats and perform essential ecological functions that are defined by their ecological niches. A microbial niche encompasses the organism’s mode of survival, including resource acquisition, reproduction, and interactions with other species in its environment. This concept is vital for understanding microbial community dynamics, biogeography, and ecosystem functionality.The fundamental niche of a microorganism includes the full spectrum of environmental...

Area of Science:

Environmental Science
Sociology
Conservation Biology

Background:

Ecological knowledge is crucial for environmental management and conservation.
A significant decline in this knowledge is currently observed globally.
There is a lack of cross-cultural and quantitative studies on ecological knowledge loss.

Purpose of the Study:

To quantitatively assess the relationship between income levels and ecological knowledge across different cultures.
To identify patterns and rates of ecological knowledge loss.
To understand the association between economic development and the social capacity for environmental management.

Main Methods:

Cross-cultural quantitative study involving 1095 interviews in India, Indonesia, and the U.K.
Analysis of the correlation between income levels and ecological knowledge.
Investigation of knowledge acquisition patterns in relation to community resource dependence and industrialization.

Main Results:

A strong inverse correlation was found between ecological knowledge and income levels.
Knowledge acquisition is faster at younger ages in resource-dependent communities compared to industrialized nations like the U.K.
Increased knowledge variance within communities is associated with declining ecological knowledge, with rapid loss observed in industrialized regions.

Conclusions:

Economic development, particularly industrialization, is linked to a decline in ecological knowledge and the capacity for environmental management.
Understanding ecological knowledge loss is critical for addressing challenges in natural resource management and preserving ecosystem diversity.
Policy interventions may be needed to support the retention of ecological knowledge in developing and industrialized communities.
