- Introduction and materials
- This unit on nature will enable students to understand and appreciate the special environmental qualities and major components of the Antarctic ecosystem.
- Southern Ocean food web
- Draw a food web for the Southern Ocean and see how animals depend on each other for food.
- Antarctic krill are one of the most abundant and successful animal species on Earth. Most of the larger Antarctic animals - seals, whales, seabirds, fish and squid - depend directly or indirectly on Antarctic krill.
- The harsh Antarctic environment has produced some very interesting adaptations and behaviour in penguins. Discover how these give the penguin an advantage.
- Sub-Antarctic and Antarctic seals have adapted to their habitat, allowing them to hold their breath and swim under water for far longer periods than we can.
- Whales belong to a wonderfully diverse group of the most aquatically specialised of the world's mammals called cetaceans.
- Southern Ocean sea birds
- Sub-Antarctic islands play a vital role in the life cycle of Southern Ocean birds. Many human pressures have caused the decline in albatross numbers and much is being done to reverse this.
- Wandering albatross
- Imagine that you are a wandering albatross, the largest flying bird in the world. You cover vast tracts of the Southern Ocean, flying up to 15,000 kilometres on a single foraging trip.
- Counting Antarctic animals
- In order to assess and predict the possible effects of environmental change and human impacts on Antarctic wildlife, it is important to have reliable data on the distribution and abundance of the key species in this ecosystem before changes occur.
- Adaptation of wildlife
- Where animals live, how they breed and what they feed on are, in part, determined by the environments in which they live.
- Diseases in Antarctic wildlife
- Many factors influence the introduction and spread of diseases in birds and seals in the Antarctic and sub-Antarctic.
- Introduced species
- The ecological balance of Macquarie Island has gone through several changes. The native fauna and flora have been affected by the introduction of several animal species and some plant species, leading to the extermination of some of the native species.
- Antarctic wildlife - comparative sizes amongst species
- Compare the sizes of some common Antarctic animals.
