History of Ecology

Ecology is the scientific study of the interactions that determine the distribution and abundance of organisms. Here is a brief history of ecology in chronological order (timeline). These include important events and contributions made by many ecologists from the dawn of time to the subject of ecology.

Origin of Ecology

In 1869, Earnst Haeckel coined the term “ecology”. It comes from the Greek word Oikos meaning “household” and logos meaning “study of”, therefore the “study of nature’s household”. Relating this definition to science, ecology becomes the study of the management of the natural environment, which includes the relations of organisms with one another and their surroundings.

Ecology as a scientific discipline is said to be multidisciplinary. It often encompasses several fields like biology, geography, and Earth science.

However, ecology is not always focused on the environment but on man. Practical applications in ecology include conservation biology, restoration ecology, resource management, and wetland management.

History of Ecology As A Science

Ecology History - A Timeline

During the pre-18th Century

4th Century B.C.E: Ecological thought is said to derive its roots from the early teachings of philosophy, ethics, and politics.
Aristotle and Theophrastus were considered the first ecologists who had an interest in studying plants and animals. Theophrastus described several interrelationships that exist between living organisms and their environment.

During the 18th Century

Early 18^th Century: Two schools of thought dominated the growing scientific study of ecology.
The first school of thought is the “Arcadian Ecology” which advocates for a “simple, humble life for man” and a harmonious relationship with man and nature. On the other hand, the second school of thought, known as the “Imperial Ecology” believes in the establishment of man’s dominance over nature through the exercise of reason and hard work.
Both views rivaled through the early years of the 18^th century until Carolus Linnaeus came in the picture.

Carl-Linnaeus

1758: Carolus Linnaeus (Carl von Linne) pioneered the field of taxonomy, the science of naming and classifying organisms. Linnaeus discovered a vast number of plants and animals and recorded them in his book entitled Systema Naturae (PDF).
Linnaeus became a huge supporter of Imperialism, and because of his immense popularity, the view of Imperial Ecology became the dominant view within the discipline.

During the 19th Century

Early 19^th century: Countries such as Great Britain, Portugal, and Spain have set several expeditions to discover new natural resources and to make records about them.

1804: Alexander von Humboldt reported an impressive number of species, particularly plants, for which he sought to explain their geographic distribution concerning geological data. One year after, he published his work entitled Idea for Plant Geography (PDF). Alexander von Humboldt was considered the father of ecology by many scholars.

1859: In this year, Charles Darwin proposed his theory of evolution and adaptation. According to this theory, organisms change over time because of their inherited traits and characters. Such evolutionary changes allow them to adapt better to their environment. These changes also ensure survival by increasing the likelihood of producing more offspring. Check out the history of evolution here.
Charles Darwin’s fame can be greatly attributed to his idea of natural selection or more commonly referred to as “survival of the fittest”. Along with Alfred Russel Wallace, who defined the role of natural selection in the formation of various organisms, Charles Darwin published all his observations, proposed mechanisms, and discoveries in his book entitled On the Origin of Species using Natural Selection.

1869: Ernst Haeckel coined the term “ecology”. Since then, ecology has become the study of the relationships of organisms with their environment.

1875: Eduard Seuss first defined the term biosphere (from Greek bios = life, sphaira, sphere) as the system composed of living organisms and their environment.

1879: Not long after, symbiosis or the living together in more or less intimate association or close union of two dissimilar organisms, was first described.

1895: Eugen Warming introduced the discipline of biogeography. As its name suggests, biogeography studies the geographic distribution of living things. Under this discipline studies, abiotic factors like wind, fire, temperature, etc., are being studied.
The ecology study was greatly enhanced by the discovery of the nitrogen cycle by Antoine Lavoisier and Theodore de Saussure. Nitrogen is considered one of the major nutrients important for the survival of all living organisms. The discovery of how it is cyclically produced into various forms paved the way for a better understanding of nutrient uptake in living organisms. Here is an interesting research article on nitrogen cycle.

20th Century up to the present

1920: The study of human ecology emerged. This discipline aimed to increase ecological science’s role in managing cities and residential places.

1926: Vladimir I. In his book The Biosphere , Vernadsky redefined the biosphere as the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, geosphere, hydrosphere, and atmosphere. Here is an excerpt from his work.

1935: Arthur Tansley coined the term ecosystem as the biological community of interacting organisms and their physical environment. Because of this, ecology became the science of ecosystems.

1940: Patrick studied interdependence of organisms, particularly freshwater ecosystems. She developed methods to measure the health of a stream.

1950: The harmful effects of pollution to ecosystems became known to people.

1953: Eugene Odum and Howard Odum wrote the first ecology textbook and ecology became a university course.

1960: The discipline of Ecology gained much public prominence because of the widespread concern for the state of the environment.

1970: James Lovelock introduced the term Gaia, or the idea that the whole earth is one living entity and will ensure its survival even if humans destroy themselves.

1971: UNESCO launched the research program Man and Biosphere in the goal of increasing the awareness of humans about their relationship with nature. More info can be found here.

1978: Conservation Biology established as a discipline focusing on environmental management.

At present, the endeavor of continuing ecological research is fueled by the desire of man to restore and conserve the planet’s ecology. Many questions on different biological phenomena remain unanswered, so quests continue.
