What Does Ecology Mean

We explain what ecology is and what are the branches of study of this science. Also, what is environmental protection.

Ecology studies the interaction of living beings with the environment in which they are found.

What is ecology?

Ecology is the branch of biology that is dedicated to the study of living things and their relationship with the environment in which they inhabit. In addition, ecology studies the abundance and distribution of living things that exist in a given area or region .

Are taken into account as factors of study within this discipline the biotic factors , which are all organisms living; and abiotic factors , such as climate and soils .

This type of interaction can be studied according to the scales or levels of organization of individuals:

  • Individual study. Study of each organism with the environment that surrounds it.
  • Study of populations . Study of the interrelation of living beings belonging to the same species .
  • Study of communities . Study of the relationship that occurs between different populations that inhabit the same area.
  • Ecosystem study . Study of communities and their interaction with the environment that surrounds them.
  • Study of the biosphere . Study of all living things in general.

History of ecology

Ecology evolved from the studies of some ancient Greek thinkers , such as Aristotle and Theophrastus (considered by some to be the father of botany ). With the fall of the Greco-Roman civilization, the field of natural sciences suffered a certain stagnation. Studies in this area became relevant again only in the 18th and 19th centuries , when the importance of studying living beings and the interactions that exist between them and the environment they inhabit was discovered. In 1789, Gilbert White wrote The Natural History of Selborne , a book for which the naturalist is considered the first ecologist in England.

Although the history of this science begins in Ancient Greece, formally the term "ecology" was created in 1869 by the German naturalist Ernst Haeckel , who defined it as "that science that studies the relationships of living beings and their environment." The term ecology comes from the Greek words oikos ("home") and logos ("study").

Some of the scientists and naturalists who with their contributions marked the path for the development of this branch of biology were:

  • Carles Linnaeus (also called Carl von Linné). Swedish scientist known as the father of taxonomy , a discipline by which all known living things could be classified.
  • Alexander Freiherr von Humboldt. German naturalist who in his explorations of the American continent collected and related information on the climate, natural resources , flora and fauna .
  • Karl Möbius. German zoologist who conducted pioneering research in marine biology, and described the interactions between organisms in aquatic environments.
  • Charles Darwin. English naturalist who raised the theory of evolution by natural selection . This theory constituted the bases of modern ecology since it proposes the mechanisms that explain the capacity of living beings to adapt to different environments .

What are the branches of ecology?

Microbial ecology is what is devoted to the study of microorganisms.

Ecology features a large number of branches. Among the most important are:

  • Microbial ecology. It focuses on the study of microorganisms in their habitat. This branch has allowed the discovery of some fundamental facts, such as, for example, that the activity of microorganisms in the terrestrial ecosystem is the cause of the fertile soil.
  • Landscape ecology . It involves the interrelation of two great sciences : geography and biology. The study is based on the observation of the landscape naturally and transformations that the action of the human being produces in them.
  • Recreation ecology. It analyzes the relationship between man and the environment, always taking the human being in a context of recreation . In this way, specific sites for recreation such as trails, corridors, games and dispersal areas are put as an object of study.
  • Ecology of populations. Study the set of living beings of the same species that inhabit the same space at the same time. Demography also comes into play here , a science that is responsible for the study of populations of the same species, which analyzes and takes into account factors such as the number of members, sex and age distribution, birth and mortality rates , among other indicators. of population.
  • Evolutionary ecology. It is based on the study of the same population over time , so it is essential to evaluate the different transformations and the changes that occur in it as a result of different influencing factors.
  • Social ecology. It involves questions of the order of philosophy since it studies the behavior of living beings as part of a group in a given area.
  • Human ecology. It studies the human being and the relationship with its natural and social environment.
  • Cultural ecology. Study the relationships between a society and its environment.
  • Mathematical ecology. Study organisms and their relationship with their environment by applying mathematical theorems and formulas.
  • Urban ecology. Study the interactions between the inhabitants of a city and the environment that surrounds it.
  • Dendroecology. It studies tree growth rings and uses the information stored in them to assess the impact of different environmental conditions on tree growth.

Importance of ecology

The greatest achievement of the study of ecology is that it allows us to know the fundamental connections that exist between organisms and the abiotic factors that make up the environment.

Over time, it was discovered that preserving these connections is critical to maintaining balance in ecosystems . Knowing these relationships allows caring for the environment , consciously managing natural resources and taking measures to anticipate environmental impact .

Ecology is a very complete and interdisciplinary branch of biology since it uses tools from many sciences to make known the characteristics of the environment.

In recent decades, ecology has gained relevance due to the remarkable consequences of the impact of human activities on the environment.

Auxiliary Sciences of Ecology

A lo largo de los años, la ecología ha ido utilizando técnicas, herramientas y datos de otras ciencias para desarrollar su estudio. Entre las más significativas se encuentran:

  • Geografía. La ecología utiliza la geografía para conocer los diferentes relieves y la forma en la que los seres vivos se distribuyen en los ecosistemas.
  • Matemática. La ecología utiliza técnicas y teoremas matemáticos que ayudan en el estudio demográfico de las poblaciones.
  • Física y química. La ecología estudia la transferencia de energía entre los distintos componentes (bióticos y abióticos) de los ecosistemas. Además, la química aporta nociones sobre la composición de la materia que constituye a los seres vivos y a los factores abióticos.
  • Geología. La ecología utiliza el estudio de los suelos y de la estructura interna de la Tierra y sus procesos para la comprensión de los biomas.
  • Climatology and meteorology. Ecology analyzes the variations in the climates of each ecosystem and the impact on its biodiversity.

Environmental Protection

Environmentalists promote the use of recyclable materials.

The environment is made up of biotic factors (living things) and abiotic factors (non-life components). Since a greater awareness was generated about the effects that abrupt changes in the environment produce as a result of pollution, ecology has been on the political agenda of all States .

To maintain the balance of our planet, it is essential that positive changes occur in the way in which human beings relate to the ecosystem that surrounds them.

This is the axis of many international groups and environmental associations that help to defend the environment through direct actions. While these organizations make complaints at the planetary level, some states sign international treaties in favor of a more efficient industrial production that does not entail dangers to natural resources or the lives of communities.

Caring for the environment must come from public policies with laws and regulations, but also from each particular individual, companies and organizations. There are some actions that can be taken to reduce the environmental impact from homes , for example:

  • Separate trash.
  • Do not throw waste on public roads or in nature.
  • Turn off lights and unplug electronics that are not being used.
  • Limit the use of running water in the shower and when brushing your teeth.
  • Use public transport or bicycles instead of cars.
  • Plant a tree on the balcony or garden.
  • Limit the consumption of products wrapped in plastic.
  • Use cloth bags when shopping.

Ecology and environmentalism

Ecology is studied by ecologists, who are scientists who study processes and relationships in the environment. Therefore, an ecologist is different from an ecologist .

From the second half of the 20th century, due to the impact of man's action in nature, groups and people called ecologists have appeared. They are part of social and civil movements and organizations whose purpose is the preservation of the environment and sustainable development.

Environmentalism transmits its messages through awareness campaigns and mobilizations to the population with the objective, in addition, that these messages reach the political and economic spheres. They seek to promote the balance of the human being with the ecosystem that surrounds it since man is part of it and not the owner of it.

Environmentalism fights against entrenched practices, economic activities and customs that put biodiversity at risk , for example: nuclear tests, deforestation, indiscriminate fishing, indiscriminate use of plastics, misuse of natural resources.
