Why the Flora and Fauna of Australia so Unique

An ecosystem contain biological communities and abiotic factors that interact with each other. However, Introduced pest species in Australia have always been a major issue due to the unique ecosystems that have developed, undisturbed over millions of years, due to Australia's geographical isolation. This is especially evident in the introduction the European red fox in Australia, which has prompt negative changes to the population of the Long-nosed Bandicoot due to the predation by these foxes in the Field of mars and around Australia. The disruption the fox foxes have on the Long-nosed bandicoot can also result in sever cascading effects on the rest of the ecosystem, including abiotic factors like the soil and biotic factors like other native flora and fauna

The all of tasmanian animals are becoming endangered from dehabitation.The t-devil are dieing from DFTD.The invasive specie are kill the t-devils by the year.People are endangered tasmanian devil and rat and invasive specie giving them disease and take there food.

(cite) Australia also had a huge desert called the Australian Outback. The Outback covers most

Over the last several years, evolution has been playing an increasingly important role in determining how various species are evolving. This is because ecology will have an impact on how quickly a particular organism is able to adapt (with: the unique challenges for a particular environment). To determine the effect that this is having requires carefully examining different species over the course of many years. This will be accomplished by comparing these changes on Darwin and Wallace Islands. Once this occurs, is when specific insights will be provided that are highlighting the underlying challenges affecting the development of organisms. This is the point that these transformations will be evident among the various life forms. (Fasolo, 2011, pp. 53 68)

Since the beginning of time our Earth has experienced many changes, these changes affected Australian biota whether it be in a positive or negative way. The study of Australian fossils contributes to the development of understanding the evolution of species in Australia in many different ways, such as seeing changes in physical appearance of species, and possible reasons why the species evolved into what they did, when and why a certain species may have become extinct and evidence/proof of theories such as natural selection. Each of these goes hand in hand and helps us find out what our Earth would have been like millions of years ago.

a) Discuss current research into the evolutionary relationships between extinct species, including megafauna and extant Australian species.

Propose reasons for the evolution, survival and extinction of species, with reference to Australian examples.

Australia is diverse it has people from Lebanon, Italy and Greece. New Zeland on the other hand is a very religious country. The people that live there are mainly from Pacific Islands but have recently been getting immigrants from different parts of Asia. There are long spanning droughts in Australia, New Zealand has droughts that only last for a short period of time. The population is way greater than the one of New

Half of Australia’s bird species, a third of frogs, marsupial and reptile species, an abundant amount of bats and butterfly species, plant and trees have been categorised to live in the Daintree rainforest, these all live in 0.2% of the landmass of Australia. Such as:

The most interesting facts is despite Australia is a sixth largest country in the world, But also begin the world's smallest continent.

Europeans settling in Australia allowed Europe to utilise the diverse land, aiding Europe and in turn the first world. Australia is 7,692,024 km², that amount of land can be used for production, habitation, and also increased European knowledge of the world. They may have learnt it the hard way, but Europe learnt a vast amount about seasons, weather, and crop farming in different places around the world when the settled in Australia. They learnt that plants need very specific conditions to grow that could not be met in Australia, and they were forced to adopt new plants from the area. Although well known European crops did not cope well with the excessive heat and lack of rain, there were alternative crops in Australia that they would have to take advantage

Q2: How effective is the current urbanisation of Canberra in maintaining biodiversity and sustainable living?

Ever since the rapid decline of Tasmanian Devils since the discovery of DFTD in 1996, it was discovered that possums were spending more time above ground and are moving away from the trees, as Tasmanian Devils were at the top of the food chain in the Tasmanian bush, but now they are missing from the ecosystem and can no longer contribute to the food web. This sudden decline of Tasmanian Devils in Eastern Tasmania, there has been a sudden increase in possums and a change in possum behaviour.

Animals and plants had to change or evolve due to environmental pressures. Over millions of years the conditions on the Earth have changed tremendously, the environmental conditions we have now are very

What is known is that humans used fire for a variety of purposes, such as agriculture and hunting. Humans learned that if a forest was cleared of undergrowth, it was easier to hunt for animals in the forest. In the Australia of 50,000 years ago, there were large animals – termed the megafauna – that the indigenous people hunted for food. Soon after humans arrived on the continent, however, the megafauna disappeared. There are several possible reasons for the extinction. One particularly dramatic one is that humans’ extreme use of fire, perhaps uncontrolled, caused the climate to become more arid, and making it impossible for some megafauna to survive. Possibly, the plants that were their sustenance were destroyed. Some animals – such as a large, emu-like bird – were hunted to extinction. (NPR) The climate of most of Australia is still arid.
