Branches of Ecology


    Branches of Ecology

    From the most gigantic known animal to the smallest bacterium, it is already given that the survival of any organism still is dependent on its adaptability to its physical and chemical environment.

    To start with, ecology is the study of the interaction of living organisms with their physical environment. Ecology comes from the two Greek words “Oikos” meaning “household” and “logia” meaning “study of“; hence literally meaning “study of the household“.

    In 1873, the term “ecology” was finally coined by scientist Ernst Haeckel. See the full history of ecology and its timeline in detail here.

    Ecology alone is a large discipline as it covers all organisms on Earth. Back then, the focus of the first ecologists are only on either plants and animals (thus only plant ecology and animal ecology exist).

    But later on, due to newly discovered knowledge and the advancement of technology, this division of ecology was no longer used. Instead, the study of ecology was again divided into two major subdivisions: autoecology and synecology.

    On one hand, autoecology deals with the study of ecology and ecosystems in single species up to the population level. On the other hand, synecology focuses on a larger level as it examines ecology at communities on spatial and temporal levels.

    Because of the still broad categories, ecology is further divided into several specialized branches that focus on a wide variety of topics. Listed below are the ten major branches of ecology.

    Branches of Ecology

    • Terrestrial Ecology

      Terrestrial Ecology

      Terrestrial ecology is a branch of ecology that deals with the study of land organisms and how they interact with each other and adapt to their environment. Aside from that, the diversity and distribution of different organisms in various terrestrial habitats are also being focused on.

      • Terrestrial ecology has a wide variety of applications like resources management, and in the long run, be effective for conservation measures.
      • Additionally, soil properties like moisture, pH, nutrient and chemical content, and soil type may be studied.

    • Aquatic Ecology

      Aquatic Ecology

      Basically the opposite of terrestrial ecology, aquatic ecology deals with the study of the ecosystems found in bodies of water, be it the marine, freshwater, or the estuarine.

      • Aquatic ecology focuses on the interactions among living organisms in a particular aquatic habitat which can directly affect various factors in the ecosystem. Such factors include competition for food and predation, temperature, nutrient concentration, and oxygen demand.

    • Microbial Ecology

      Microbial Ecology

      Microbial ecology focuses on the study of how communities of microorganisms establish themselves on abiotic substrates and how such organizations enable them to interact with each other.

      • The scope of microbial ecology is quite huge as it can cover the vast micro-flora in animal guts, the seemingly simple yet actually genotypically complicated bacterial communities called the biofilms, and the complex relationship between prokaryotes and eukaryotes that somehow led to their divergence.

    • Systems Ecology

      Systems Ecology

      Systems ecology is a branch of ecology that tackles various abiotic factors like energy budget allocation and physical processes such as carbon cycle and biogeochemical cycles.

      • This branch of ecology is distinctive because it integrates other scientific disciplines like applied mathematics and computer systems to study and predict structures and function in a given ecosystem.

    • Taxonomic Ecology

      Taxonomic Ecology

      The next branch of ecology might be new to some as it incorporates two field of studies that may not appear to work often. Basically, taxonomic ecology is a new concept in this field.

      • The use of taxonomic data is highly important as it improves the study of the ecosystems by helping identify key organisms present in that area. Aside from that, this branch of ecology helps in the easier classification of organisms, whether each act accordingly or antagonistically with each other in the community level.

    • Evolutionary Ecology

      Evolutionary Ecology

      Evolutionary ecology merges the two scientific studies of evolution and ecology and focuses on the the physical and genetic changes that occurred among organisms and how such modifications were affected by ecological factors.

      • Basically, it also considers the effect of forces like competition, predation, parasitism, and mutualism in the evolution of individual species, in a population, or in the entire community.

    • Population Ecology

      Population Ecology

      As its name suggests, population ecology deals with the study of population structures and dynamics, rather than looking at the individual behavioral patterns of living organisms.

      • Population ecology studies the various factors that affect population size, density, dispersion modes, and growth rate and mortality rate.

    • Behavioral Ecology

      Behavioral Ecology

      The next branch of ecology, behavioral ecology, integrates the study of the interaction between survival value to the behavior of organisms and their offspring. Interestingly, it somehow related to evolutionary as it examines how an organism changes its behavior to ensure survival and perpetuation.

      • At present, this branch of ecology attempts to find the link between an animal’s behavior to its environmental adaptation and reproductive success.

    • Conservation Ecology

      Conservation Ecology

      Conservation ecology, as its name suggests, studies the management of biodiversity through conservation and restoration methods. This branch of ecology had just recently evolved to address the decreasing biodiversity and deteriorating natural resources in the planet.

      • This branch is interdisciplinary and utilizes principles from genetics, biogeography, population biology, environmental ethics, and law to help in ensuring the conservation of species and their habitats.

    • Applied Ecology

      Applied Ecology

      Bringing together all the concepts and principles of ecology, applied ecology aims to apply these significant knowledge, findings, and technological advances to understand real world situations and to address practical human problems.

      • Applied ecology includes applications like management of wildlife and natural resources, epidemiology, and even natural disaster risk reduction and management.
      • The scope of applied ecology is huge and encompasses the fields of biotechnology, ecology, to study how anthropogenic activities affect not only micro-systems but the biosphere as well.

    1. […] Ecologists look at the science behind how organisms interact with their surrounding environment, including living (biotic) and non-living (abiotic) things. An example might be how humans impact the environment. […]
