Australian Fauna 

A DISTINCT ECOSYTEM 

 

     The entire sole continent of Australia provides a exquisite landscape, ranging from virtually pristine antartic territories and rainforest, to the significant climate of the raging desert dry lands. The land does not just qualify for droughty climate conditions, as plenty of vegetation, wildlife, and patterned weather still occupy a majority of the coastlines, towards the outer-terrian of the continent. Even so, despite weather similarity, Australia still holds it's dangerously unique title of a landscape- with days as heated as 50.7 °C (123.3 °F) in the Victorian desert, to below freezing nights as cold as−23.0 °C (−9.4 °F). A vast predominance of central Australia is very dry due to dessicate climate and little moisture. The interior has a number of deserts while most of the coastal areas are populated. Approximetly 80% of the entire continent's population is inhabited 20 miles off from the coasts of Australia- where land remains fertile. Northern Australia experiences tropical cyclones while much of the country is prone to periodic drought. As seen left on the continental map, Australia's topography is abundant with woodlands and vegitation. As like most shoreline habitations, wildlife and greenery still strive depsite of the contient's geographical dry climate and features.

 

       All desert organisms occupant to Australia's dry lands have faced the same series of plights. Such difficulty is from the ecosystem's lack to provide water, and a scarcity of patterned weater structure. This absence of fresh water creates a survival problem for all desert organisms, as it is an essential for all biotic viability. Animals have an additional problem - as they are more susceptible to extremes of temperature than are plants. These fuana receive heat directly by radiation from the sun, and indirectly, by conduction from the substrate (rocks and soil) and convection from the air. The biological processes of animal tissue can function only within a relatively narrow temperature range. When this range is exceeded, the animal dies. Combined with the paucity of life-sustaining water, survival for desert animals can become extremely tenuous. They have evolved both behavioral and physiological mechanisms to solve the heat and water problems the desert environment creates. Some characterizing adaptions developed by these species are abilities such as advoiding heat, disipating heat, and retaining their sources of water. The genetic modification of having pale outside shedible skin for desert animals disperses radiational and convectional warmth. Among the thousands of desert animal species, there are almost as many remarkable behavioral and structural adaptations developed for avoiding excess heat.
