Ecology Definition

Ecology is the study of relationships between organisms and their environment.
It encompasses the relationships between organisms and other organisms.
Ecology involves studying the natural systems' structure and functions.
The word "ecology" was first used in 1866 by Ernst Haeckel.
Haeckel based the term on the Greek words "oikos" (household) and "logos" (study).

Primary Objectives of Ecology

Studying the changes in populations of organisms.
Studying the flow of energy and matter (substance) within living systems.

Additional Objectives of Ecology

Establish a scientific basis for using biological resources.
Develop methods to minimize the use of harmful chemicals to control organisms.
Control populations of living organisms.
Identify and assess the environmental status and contamination of natural habitats.
All objectives focus on sustaining biodiversity, which is crucial for sustainable natural and societal development.

Structure of Modern Ecology

Modern ecology heavily relies on experiments in both laboratory and field settings.
These techniques help validate ecological theories and provide practical management decisions for natural resources.

Structure of Modern Ecology (Diagrammatic Representation)

The diagram shows interconnections between different aspects of modern ecology.
The diagram highlights factors like consumerism, biodiversity, nature, environmental management, human diversity, human production, and managing resources for livelihoods.
It depicts the importance of these interconnected ideas relating to the cultural superstructure, economic base, and the management of natural resources.

Relationship of Ecology with Other Sciences

Ecology is a multidisciplinary science that draws upon many other branches of science.
Applied ecology involves implementing ecological principles to solve real-world problems.
Examples include calculating fish populations, assessing environmental impacts (construction/logging), and justifying species conservation.

Sections of Ecology

Ecology is closely linked to various natural and human sciences including chemistry, mathematics, physics, geography, medicine, economics, and law, etc.

Biological Ecology

Biological ecology focuses on the conditions that support the existence of living organisms.
It studies the relationships between organisms and their environment.

Autecology

Autecology investigates the specific characteristics of living organisms.
It considers factors like adaptation to the environment (temperature, humidity), salinity, growth, reproduction, metabolism, food composition, respiratory rate, and photosynthetic rate.

Population Ecology (or Demecology)

Population ecology focuses on the characteristics of populations.
It examines factors like species quality, varying ages, sexes, and phenotypes.

Sinecology (or Community Ecology)

Sinecology studies species composition in communities, their patterns, and community changes over time.

Global Ecology

Global ecology explores the interconnectedness of all Earth's ecosystems.
It involves the lithosphere, hydrosphere, atmosphere, and the biosphere.
(Biosphere—The globally interconnected system of all ecosystems, all of which are in close linkage.)

Environmental Engineering

Environmental engineering examines the interactions between communities, natural habitats, and human production processes.

Human Ecology

Human ecology focuses on preserving and improving human health.
It considers the relationship between humans and their surrounding natural and social environments.

Social ecology investigates how societies interact with the natural world.
It covers radical changes, technological advancements, economic factors, societal values, cultural influences of civilizations, strategic approaches, and tactics in remaking the natural world.

Space Ecology

Space ecology is a relatively new area that studies manned satellites as artificial ecosystems, along with the effects of the space environment on human organisms.

Importance of Ecology

Studying ecology provides significant knowledge of natural ecosystems.
Human economies rely on the exploitation and management of natural resources.
Applied ecology is commonly used in areas like forestry, fisheries, range management, and agriculture to produce food and fiber.

Importance of Science of Ecology

Ecology is crucial for human existence.
Ecology increases our understanding of ecological knowledge.
Ecology highlights the environmental impact.
Ecology helps predict and prepare for future effects.
Maintaining the stability of ecosystems is essential for all life.

Sustainable Development

Sustainable development balances present needs with the potential needs of future generations.
Example for sustainable development is "Clean Water" which shows the need for clean water, water recycling, and reducing water waste.

Conclusion

Sustainable practices are essential for the preservation and future of humankind.
There is a need for solutions to correct past mistakes in a timely manner.
There's a need for proactive strategies (action plans) versus just discussing problems.
