The Biological Adaptions Of Animals

Marsupials living in Australia’s hot arid environment must deal with exposure to extreme conditions such as high temperatures, solar radiation and limited food and water supply. More than 50% of the world’s marsupial species occur only in Australia (Steffen et al 2009), which indicates their ability to adapt to Australian

Antarctica has one of the only two polar ice caps on the planet Earth. It is called the Antarctic ice sheet and it covers about 98% of the Antarctic continent. Wikipedia says this is the largest ice mass on Earth; it covers about 5.4 million square miles, and is

“Penguin responses to climate change in the Southern Ocean” by Jaume Forcada and Philip N. Trathan (2009) was a study conducted to analyze and predict the migrating patterns of different species of penguins due to changes in climate. (p. 1618) Also, Forcada and Trathan investigate whether or not certain species of penguins possess phenotypic plasticity (the ability of an organism to change its phenotype in response to changes in the environment) (p. 1618).

In conclusion, one can see that there are organisms that they may not have known exist or know anything about. This unit takes the reader around the world to observe beginiing with the Soran Desert, Antarctica, Yellowstone, Great Barrier Reef, Deep Ocean, and Central Park. Learning about habitats and the settled life forms that thrive for survival. Seeing the variety of temperatures these animals are settled in along with their weight and length. Frigid climates have animals that are adapted to

As a result of the high latitude the climate is cold and another factor is that it is near the Arctic climate region. The majority of the year it is quite chilly and the temperature rarely surpasses twenty degrees Celsius. However when it does go above ten degrees Celsius many birds migrate to this park, like the snow geese I illustrated beside the park's monitoring centre. The park only has about four-five months above zero degrees, and since the area is tundra there is permafrost also the area has very poor drainage causing the wetlands. Overall, the climate is cold, with a very large temperature range with moderate relief precipitation.

Antarctica is certainly the most pristine environment left on the earth. Unfortunately this is no longer the case because of multiple human activities that have led to environmental issues and concerns such as pollution, ozone layer thinning, global warming etc. Human impact is a serious threat to ecosystem and food chain of Antarctica.

What makes Antarctica unique regarding human geography, is how humans influenced the continent. physical geography is far more significant than human appearance. Antarctica is a cold, frozen, and mostly empty land found at the South Pole of the earth.

The Antarctica has an ice shelf that is several miles wide around it. The sun never sets in the summer but sections of the ice shelf never melt. The Emperor penguin has been using these sections for breeding places for many years. These breeding areas are called rookeries.

The ice never melts; it clings to the bottom of the world, spawning winds, storms, and weather that affects the whole planet. And of all the weather it creates, the weather the Antarctic creates for itself is by far the worst. In the winter, the temperature can sink to 100 degrees below fahrenheit. Cold air masses sliding down the sides of the glaciers speed up until they become winds of close to 200 miles per hour. When winter descends on the southern continent,

c) Antarctica is colder and windier than in the Arctic. The lowest temperature ever measured, -89.2°C, was registered Vostok in Antarctica on 21 July 1983 (Kranz). The positioning of the Antarctica renders it lightless since no sun rays reach the region making it extremely cold than the Arctic

To many Antarctica is a very cold, dangerous, isolated and uninhabited place with nothing to offer the world but Antarctica is a remarkable and unique continent. Antarctica provides great insight into how the world works, and the consequences of human activity. Antarctica belongs to no-one and everyone, unlike most places no native people ever lived there due to the difficult environmental conditions, so no one ever really settled in Antarctica therefore it is not a part of any one country.

Organisms can live in harsh environments without being prone to danger. The Arctic includes the world's smallest ocean being the Arctic Ocean, as well the world’s largest island, Greenland. In regards to the Arctic, its ocean is covered in floating sea ice throughout the year. The climate of the Arctic varies a lot during the seasonal changes. In the months in the winter season, the sun doesn’t pass the horizon in the Northern Arctic, which in result the temperature significantly be depleted in some areas to -60 degrees Celsius, but to differentiate, during the warmer months of summer, temperatures can cause some areas of the Arctic to melt, due to temperature reaching of 20 degrees Celsius. In the Arctic, the Environmental conditions vary

subarctic north (very cold and snowy) the majority of the population inhabits the south. The

Antarctica was not always the frozen, dry continent we know it to be presently. Two hundred million years ago, it was the center of a “supercontinent” called Gondwana that included parts of South America, Africa, India, and Australia.

The geography of Antarctica influences the way the country is governed because it’s covered completely in ice. Because is this, Antarctic doesn’t have it’s own official government, language, or culture. Antarctica, a vast continent on the South Pole, is many kilometers away from the equator, and isn’t very warm, ever. That’s why the only people who live on Antarctica are never permanent and are simply biologists and other branches of science. That’s the one of the only things people are allowed to do in the cold space of Antarctica.
