Study Ecology and learn more about the world we live in

Ecology is the study of the relationship between plants and animals and their physical and biological environment. In this course, you'll learn about different types of ecology, including:

  • behavioural ecology
  • population ecology
  • community ecology
  • ecosystem ecology

You'll also learn about several different biomes, large, naturally occurring community of flora or fauna adapted to particular conditions in which they occur. Biomes are influenced by latitude, elevation and associated moisture and temperature. Examples of these communities are tundras, deserts, wetlands, forests, include their associated freshwater communities, such as streams, lakes, ponds and wetlands. Terrestrial biomes vary geographically from the tropics through to the Arctic and Antarctic regions.

This course provides an important foundation for one very important area of environmental study. Useful for people in:

  • environmental management
  • agriculture
  • horticulture
  • research
  • education
  • wildlife and animal studies and welfare

Student Comment: "I love the course and the course material even though a bit of it seems to be a lot more in depth than I anticipated. I love it just the same as I'm learning lots. I just wish I had more time to do a lot more." Kim Stinton - studying Introduction to Ecology as part of an Advanced Certificate in Wildlife Management.

Duration:  100 hours

Course Aims

  • Identify the components of an ecosystem and demonstrate how they interact
  • Discuss the basis of the Theory of Evolution and those elements of science which influenced the theory
  • Discuss the existence of animals in the ecosystem.
  • Discuss the presence of plant life in a range of ecological situations.
  • Discuss the ecological features of mountains, rivers and deserts.
  • Discuss the ecological features of shallow water regions and coral seas.
  • Discuss the ecological implications of human activities on the environment.

What you will do

  • Observe an ecosystem in your local area.  Identify the inhabitants of the ecosystem and their location in the food web of that system.
  • Compare the similarities and differences between the detrital web and the grazing web
  • Discuss what scientific discoveries the Theory of Evolution, both past and present, is based on.
  • List and explain the four arguments of evolution.
  • Define Natural Selection.
  • Discuss how genetics are related to evolution.
  • Go to an ecological environment (as natural as possible, with minimal human interference) and observe the plants and relationships that exist. 
  • Visit a local stream or river. Observe the condition of the stream, particularly the presence of indigenous vegetation and its affect on stream bank condition. Also look for evidence of human activity on the condition of the stream or river
  • Discuss, in your own words, the theories which have been advanced in the past regarding the formation of coral reefs.

Why Do We Need to Understand Ecology?

All life on earth is connected -animals, plants, humans. The way in which we are interconnected is critical to our long term survival. When these interconnections are not sustained properly; a species runs the risk of declining in numbers, and possibly even becoming extinct.

BIOMES
Biomes are a large, naturally occurring community of flora or fauna adapted to particular conditions in which they occur. Biomes are influenced by latitude, elevation and associated moisture and temperature. Examples of these communities are tundras, deserts, wetlands, forests, include their associated freshwater communities, such as streams, lakes, ponds and wetlands. Terrestrial biomes vary geographically from the tropics through to the Arctic and Antarctic regions.  

The term biome is used by some ecologists, but others may call these broad units of vegetation "plant formations".  The major difference between the two terms is that biomes include the associated animal life; however, major biomes are identified by the name of the dominant forms of plant life.

Some ecologists also consider marine environments to be biomes which include:

  • open ocean
  • littoral (shallow water) regions
  • benthic (bottom) regions
  • rocky shores
  • sandy shores
  • estuaries
  • tidal marshes

Threats to Rocky Shores

There are a number of factors that can be very beneficial to a harmonious rocky shore ecosystem, but, as exposed to environmental or human factors as they are, there are a number of challenges these environments must face. Among the most commonly known threats a rocky shore environment may encounter are: 

  • Oil pollution from ships in distress or ships that flush out their bunkers while passing off the coast. The flushing of bunkers is illegal, in the waters of most countries, and usually carries heavy penalties. Unfortunately proving liability is very hard.
  • River pollution brought to the shores by rivers. Sewage in the river can carry diseases such as cholera, which can be taken up by shellfish. If people later eat these shellfish, they can become infected.
  • Sewage outfalls. In many countries raw or partially treated sewage is disposed of directly to the sea. This can be spread by sea currents and wave action onto shorelines.
  • Algal blooms caused as a result of excess nutrients in the water, often discharged from nearby rivers can seriously affect local marine organisms. Shellfish may take in toxic algae that can harm animals, including humans that eat the shellfish, while heavy algal blooms may reduce dissolved oxygen levels in the sea water carried onto the rocky shore, seriously affecting marine organisms.
  • Many rocky shores are subject to indiscriminate bait, shell and rock pool life collecting.  These activities can rapidly deplete a rocky shore of organisms, and can seriously affect local food chains, which may further affect other organisms.
  • Foot traffic and dislodgement of rocks, by fishermen, tourists, etc. can also cause extensive damage.
