🗂️ Taxonomic Ecology Research Topics

Taxonomy is the study aiming to classify all living and extinct organisms. That’s a lot, right?! However, there are particular methods in this field to make the process easier. The systems of botany and zoology divide all organisms into groups, which forms hierarchies. Moreover, there are internationally accepted systems, such as binominal nomenclature . Each of the living and dead bodies has its place in this system.

  • Historical analysis: What was the role of classifying medicinal plants in China in the later hydrological studies? It is not a surprise to the experts that creating catalogs goes back to ancient China. The main focus was on the most useful plants since they were used for medical purposes. However, it appears that such an approach also allowed some further hydrological studies.
  • How did Carolus Linnaeus develop his classification system known as nomenclature, and how is it different from Aristotle’s approach? If you look back to Aristotle’s attempts to classify all living organisms and compare them to the Linnaeus system, you can see that there is a catch. Linnaeus binomial nomenclature was a result of quite a few failures. Therefore, your main task for this essay would be to try and find out how the founder of modern taxonomy worked.
  • What are the main reasons that so many living organisms and their groups are still not identified and poorly studied? It may be hard to believe, but the vast majority of living things are not studied thoroughly. To make it more shocking, even more of them are not classified yet! As a specialist who wishes to do research or write a paper on taxonomy, your task will be to determine the main reasons for such occurrences.
  • Suggesting the course of specimen’s evolution: How successful usually the last step of the taxonomical method is? Modern taxonomical methods consist of several simple steps. It all begins with finding a specimen and then comparing it to the existing ones. The purpose is to find a suitable place for it in nomenclature. You need to see what of the available evidence helps identify the course of evolution and how accurate it usually is.
  • What are the reasons to believe that numerical taxonomy would be more effective and what may be the difficulties while using it? Some ecologists have a faith that numerical taxonomy can be somehow more effective. For this essay, you should be able to recognize the reasons they have for such claims. However, no method is perfect. There are a lot of contradictions around this one.
  • How different is the code for cultivated plants from the rest of them, and why it had to be established separately?
  • The differences between collecting and preserving techniques of two groups of organisms of your choice and difficulties of their observation.
  • Why do some taxonomy and genetics specialists say that each organism can only be classified if its genotype is available?
  • Classifying fossils : What appears to be the main issues if little is known about a fossil, and how does it result in phenetic classification?
  • The most effective ways to classify viruses as the organisms whose evolution and ancestral forms cannot be identified correctly.

Applied ecology, like any other applied discipline, uses knowledge to address real problems. These problems are not necessarily only ecological but rather combine aspects of different fields.

Applied Ecology Research Topics

Unlike some of the more theoretical subfields of ecology, applied ecology is where all the action happens. It studies how the newest ecological findings can be used for real-world issues. It appears that this area of research is also closely related to conservation ecology. Besides, applied ecology focuses on habitat and agroecosystem management, restoration ecology, and ecosystem restoration. This field is worth digging into, so we prepared some of the most interesting ecology topics in this section!

  • How much attention should be brought to the non-consumptive use of biota such as tourism in applied ecology? Applied ecology does not only focus on managing the natural resources that we need for survival. As humans, we use a lot of biota for recreational reasons. What is the perspective of applied ecology on such a use? Your task is to engage in the discussion on this topic!
  • What is the role of explicit timescales in applied ecology , and how are the management decisions are made under the pressure of time? Everyone knows that time is money. However, sometimes, much more important things depend on the time available. In applied ecology, specific time frames affect a lot of decisions and options. If you decide to choose this topic, you would need to focus on the issues that arise whenever there are strict time frames
  • Landscape-scale: How does the perspective change the methods used in applied ecology, and what is the use of large-scale view? It appears that a lot of things vary depending on the perspective. Applied ecology is not an exception. For example, when the specialists deal with forestry, they need to consider this aspect. In this case, many management issues are related to the processes found in relatively large areas.
  • Historical analysis: Where did the concept of carrying capacity originate from, and what does it have to do with cattle production on rangeland? This term is used in both basic and applied ecology and means the maximum population size that a particular environment manages to sustain. Many other definitions might highlight quite different aspects. However, your main task for this topic would be to look into the origins of this term in applied ecology.
  • The importance of studying the long-term environmental changes as they influence the higher levels of biological organization. By now, you can probably see how many vital issues applied ecology has to deal with daily. The topic of environmental changes is one of them. However, you might want to narrow it down and choose a specific species to consider. Moreover, if you need a more complex research topic, pick a particular environmental change.
  • Air pollution and how to solve this problem.
  • Limited information as one of the main challenges in applied ecology when making effective management decisions.
  • Global warming: Realities, challenges and solutions.
  • How useful are diatoms as the tools for exploring and interpreting applied ecology problems, and how are they used?
  • The soft-path approach for sustainable water management.
  • Waterfowls’ role in wetland habitats as the means of wetland restoration designs that can also benefit multiple other species.
  • Water treatment system for saline bores in Cape York .
  • A case study of the impact of specific pollutants that affect pollinator activity in road verges and how it concerns other species.
  • Sustainable gas production in the UAE.
  • Environment-friendly freight: An overview.
  • Renewable energy and sustainable development.
  • Climate change: How Exxon misled the public.
  • Eight methods of raw water purification.

Conservation Ecology Topics for Research

This branch of ecology had only recently started developing but already found some useful applications in the field. Conservation ecology deals with the means of preservation of biodiversity and natural resources. You may have heard about the current sixth extinction. Well, conservation ecology is one of the ways humanity uses to slow it down. This field uses other disciplines such as biogeography, environmental ethics, and even genetics. If you want to work with some of the most critical topics in ecology, check out the list below!

  • What agricultural practices have been presented as climate-smart but do not meet the requirements for helping climate change issues? Climate-smart agriculture techniques have been used in conservation ecology for a while now. The primary efforts are focused on supporting farmers by increasing productivity while reducing greenhouse gases and adapting to climate change. However, recently some of the climate-smart solutions that do not address those issues have been claimed to do so.
  • The influence of positive and negative framing in the campaigns that encourage people to support conservation ecology projects . When people tune in to the news about the ecological situation regarding biodiversity, all they hear is negativity. The predictions are quite discouraging since we are doomed to lose so many species, and the rates of extinction are increasing. However, what if the perspective was on the brighter side? Some organizations focus on the positive future that we can achieve by taking action right now.
  • What tools are used in marine protected areas to support sustainable use of that environment and the role of marine spatial planning in it? People do not usually associate marine spatial planning with the protected areas. However, this method helps analyze the marine space and inform the responsible divisions. It also appears that the areas that are vital for conservation reasons come as some of the most common data layers within the marine plans.
  • The conflict between the new and old approaches to conservational ecology and its effect on other academic disciplines. The specialists and supporters of conservation to protect nature have been divided into two groups. It seems like the new conservationists see this field as more adjustable and ready for changes. Simultaneously, the traditional values supporters prefer to stick to their established methods of managing ecosystems.
  • What methods can conservational ecology use to determine when and why a specific ecosystem reaches a critical resilience threshold? Ecosystems are adaptive structures, and they can bounce back after the disturbances and regain their functions. However, human activities cause ecosystems to become more vulnerable. The resilience is getting worse due to environmental thresholds such as biodiversity decrease and climate change. In your essay, you should study this question in detail.
  • From the perspective of conservational ecology, is it more important to focus on maintaining the evolutionary capacity or preserving current levels of diversity?
  • Global warming: Effects on the wildlife and conservation initiatives .
  • Changes in animal responses to climate and natural disturbances should now be considered normal and regular events during conservation projects.
  • What is the importance of thiamine and its availability to protect and conserve some species in the northern hemisphere?
  • The genetic pesticide control approach and the potential threats it may bring on the nontarget species.
  • Laser beams as the innovation aimed to help catch ocean fish and the issues with the speed of fish replenishing their populations.
  • Genetically modified organisms in farming.

Functional Ecology Topics

Functional ecology studies how ecosystems function. However, it is not the whole truth. The thing is that this subfield focuses on how different species influence the environment they inhabit. Special attention is brought to their natural traits. For example, the specialists would study how some plants’ defense mechanisms alter the way their ecosystems operate.

  • The significance of Charles Darwin’s works considering the effects of biodiversity on ecosystem health for modern functional ecology. Even though this topic has some historical hint to it, you would be mainly working on linking Charles Darwin’s works with the study of functional ecology how we know it today. Try to find some of his writings that directly connect to this issue and pick the main one. For example, On the Origin of Species might be a great start!
  • Case study: What are the reasons why, in some situations, diversity shows an adverse effect and slows down ecological productivity? In general, biodiversity is a good thing. It positively impacts the productivity of an ecosystem. Not only it regulates the most effective and efficient exchange of energy and matter, but it also helps produce extra resources useful for humans. However, nothing is perfect. Sometimes, it happens that diversity causes more issues than brings profits.
  • What are the benefits and potential threats of implying complex functional diversity models in larger scales in functional ecology? It seems like most of those models are usually applied on small scales. However, it is suggested that more functional groups of a particular species can positively affect the ecosystem functions. On the other hand, it is the idea that has some limitations. Your task would be to analyze those potential issues that may or may not occur.
  • How does functional ecology help in species detection and classification, and how is it different from other approaches? When the specialists try to detect a species, they measure and analyze its unique traits. However, the likelihood of a minor mistake is always there due to the limitation of such data. Therefore, some other approaches should be used instead of or in combination during such research. Functional ecology is a great help in this case.
  • Functional ecology and de-extinction: What aspects do researchers consider while planning on reintroducing an extinct species into an ecosystem? The science of de-extinction is very delicate . A full functional analysis needs to be performed before placing a species into the ecosystem that previously assisted in its extinction — no wonder the specialists need to include many aspects into such research. Your task for this topic is to look into them.
  • Functional ecology: The importance and applications of the understanding of ecosystems with the help of functional diversity.
  • Explaining climate science in the modern world: The role of humans in climate change.
  • What are the benefits and disadvantages of using screening and empiricism to study the species traits in functional ecology?

essay questions on ecology

5 Best Ecology Essay Topics for College Students

essay questions on ecology

Living things rely on their environment for survival. Without it, no living things, including human beings, would survive. Unfortunately, people are consistently destroying habitats through various activities. They do mining, farming, build cities, infrastructure, and dump waste on the environment. 

These activities have devastating effects and cause ecological imbalances. When writing an essay on ecology, choosing an interesting topic can be daunting. The field is wide, which makes it harder to get the best topic. Here are five attractive topics you can consider.

Why marine ecology is important in the 21st century

71% of the earth is water which is home to about 50% to 80% of all living things. Oceans are crucial in supporting survival on earth. They significantly contribute to keeping the earth cool, air circulation, rainfall, food, and jobs. A lot of pollution that happens on land eventually finds its way into the water. 

In the long run, salinity levels, PH, water density, and oxygen levels get affected. Some organisms migrate from their habitats and become alien or invasive species. A student can discuss the negative effects of invasive species on ecosystems. 

They can focus on marine pollution and the involvement of human beings in destroying marine ecosystems. The topic can be wide, but many students seek writing help from professional writers when they want to create the best quality essays. 

What will ecology look like in the future?

essay questions on ecology

When studying ecology, it is important to look into past and present activities and then project how they will affect the future. The actions of the past and present will determine how living things will survive in the future. All life may fail to survive, or it may change to different adaptation strategies. Some of the areas a student can explore on this topic are:

  • How will global diversity look like in future
  • The growing human population and its effect on future ecosystems
  • Afforestation and future wildlife survival 
  • Surviving in a zoo. The biological effects and ethics. 
  • Can human beings survive without other creatures?
  • How future temperature extremities will affect survival on the earth
  • The impact of human activities on the ecosystem and conservation biology

The impact of urbanization on ecosystems

Since the earliest civilization, human beings have been building cities. They choose the best places with enough water supply and other natural resources. As people migrate into towns, they grow bigger into cities. The growth process significantly impacts ecosystems, yet the impact is irreversible. Forests are destroyed, animals lose their habitat, species interactions get altered, and freshwater sources get destroyed. 

The growth of cities can be termed as positive, but it undermines biodiversity. It creates a huge disconnect between human beings and nature. It affects land use, introduces foreign species, and impacts climate change. The irony of the matter is that human beings rely on the environment for survival. 

Environmentalists and conservationists need to ask themselves the harder questions. How will native animals and plants survive amid vast urban developments? These are areas a student can explore and create topics that focus on specific effects both currently and in the future. 

Special adaptation of non-native species and their threat to native species

Most non-native species were introduced into their current habitat by people. Other types found themselves in a new ecosystem as they migrated in search of better survival. The disadvantage with them is that they develop better survival mechanisms than their host or native species. 

They have better tolerance, reproduce faster, and can survive in marginal places. In search of survival, they prey on native species and cause huge imbalances in the ecosystem. In an effort to control them, human beings often use chemicals that make matters worse. Globally, the total cost of controlling invasive species exceeds $1.3 trillion within the last 50 years. A student can explore several areas such as:

  • The impact of invasive species on the ecosystem
  • How human evolution can help manage invasive species
  • How invasive species threaten the existence of native species

Public health and the ecosystems

Public health has a direct relationship with healthy ecosystems. The ecosystems provide human beings with medicine, fresh air, clean water, raw materials, and energy. When the ecosystems provide contaminated water, poor quality food, and polluted air, the public suffers deeply from various diseases and sicknesses. 

Everyone who benefits from the environment is a direct partaker of its conservation. This includes the government, communities, and individuals. As the health of the environment improves, public health improves too. 

All living things are interrelated, and one depends on the other for survival. This includes human beings, plant life, and animal life. Human beings have been important in the destruction of habitats through their activities. A student can choose various topics on ecology and write an attractive essay. The topics can range from marine life to urbanization, future ecologies, and invasive species. A student should give focus on each topic and develop arguments or points that are relevant.

essay questions on ecology

  • Ecology is the study of how organisms interact with one another and with their physical environment.
  • The distribution and abundance of organisms on Earth is shaped by both biotic , living-organism-related, and abiotic , nonliving or physical, factors.
  • Ecology is studied at many levels, including organism, population, community, ecosystem, and biosphere.

Welcome to ecology!

Biotic and abiotic factors.

  • Maybe the mold needs a certain amount of water to grow, and this amount of water is found only in the shower. Water availability is an example of an abiotic , or nonliving, factor that can affect distribution of organisms.
  • Maybe mold feeds off of dead skin cells found in the shower, but not in the dresser. Availability of nutrients provided by other organisms is an example of a biotic , living-organism-related, factor that can influence distribution.

Case study: the red panda

How do ecologists ask questions, ecology at many scales.

  • Organism: Organismal ecologists study adaptations , beneficial features arising by natural selection, that allow organisms to live in specific habitats. These adaptations can be morphological, physiological, or behavioral.
  • Population: A population is a group of organisms of the same species that live in the same area at the same time. Population ecologists study the size, density, and structure of populations and how they change over time.
  • Community: A biological community consists of all the populations of different species that live in a given area. Community ecologists focus on interactions between populations and how these interactions shape the community.
  • Ecosystem: An ecosystem consists of all the organisms in an area, the community, and the abiotic factors that influence that community. Ecosystem ecologists often focus on flow of energy and recycling of nutrients.
  • Biosphere: The biosphere is planet Earth, viewed as an ecological system. Ecologists working at the biosphere level may study global patterns—for example, climate or species distribution—interactions among ecosystems, and phenomena that affect the entire globe, such as climate change.
