Divisions of Biology: Ecology

Ecology, popular to us as a stream of science has a deeper meaning to it. The term is derived from Greek words that mean ‘Study of the House.’ This branch of science involves the scientific analysis of organisms in the environment. Organisms can be both living and non-living. It is a subject that focuses on the nature of interaction between organisms and also their physical surroundings. In a nutshell, Ecology is the study of Earth’s Ecosystem.

History of Ecology

History of Ecology

The term 'Ecology' comes from the Greek word 'Oikos' meaning “Household” & 'logos' meaning “Study of”. Here is a brief history of ecology and its timeline.
Speaking of ecosystem, everything from a rock to water, bacteria, fungi, animals and plants to protists and atmosphere is all included under the broad concept of an Ecosystem.

Ecologists take a close look at sectors like the population of organisms, diversity, biomass and distribution. First discovered by the German Scientist Ernst Haeckel in the year 1866, the term Ecology simply signified a combination of Biology and Earth Science.

After years of progression, this subject has been categorized as interdisciplinary. All organisms form a major part of an ecosystem. The communities formed by these organisms are a crucial subject of study in Ecology since the course demands an understanding of relationships between organisms and their environment. Ecologists are also expected to understand the pattern and flow of energy in an ecosystem. To figure this out, processes like pedogenesis, niche construction, primary production and nutrient cycling are put into use.

Ecology covers the topic of biodiversity as well. As a student of ecology, you are expected to rack up maximum knowledge about the diverse species and genes that create a complete ecosystem. Since Ecology has very much to do with human science, coming across subjects like natural resource management, community health service, wetland management, conservation biology, city planning and human ecology or in other words study of social interaction between human beings is very common.

What will you study after taking up Ecology as a chosen course?

Since our Ecosystem is unexpectedly vast, you as a student will be asked to gain insight on a variety of topics. Some of them include:

  • The concepts of Hierarchical Ecology
  • What is a Habitat?
  • Biome and Niche
  • Atmosphere and Biosphere
  • Population Ecology
  • Biodiversity
  • Understanding of the Food Web
  • Behavioral Ecology
  • Biogeography
  • Evolution


Aberdeen Eco-News

Aberdeen Eco-News is a newsletter published by a group of environmental activists in Aberdeen (oddly enough!) in North-East Scotland. It is not aligned with any particular political party, and has no hidden agenda – only the very up-front aim to promote environmental issues and linked causes, and to bring them to the public’s attention. In our paper version, we do this only within the city where we live; in our electronic version, we hope to spread the word to a wider audience. Enjoy!
