The Impact of Climate Change on Leopard Seals (Hydrurga leptonyx) Leopard seals (Hydrurga leptonyx) are a species of ice-obligate seals that are widely distributed in Antarctic and sub-Antarctic waters (Hückstädt, 2015). The most recent circumpolar estimate of leopard seal abundance suggests more than 35,000 individuals, and there does not appear to be a declining trend on these numbers. The IUCN, for this reason, list the leopard seal as Least Concern (Hückstädt, 2015). However, climate change
Introduction The Permian-Triassic extinction event is undoubtedly the largest extinction event the Earth has ever seen. While evidence shows that it occurred over a great amount of time, it was effective in causing the extinction of an incredibly large portion of life on Earth. To such an extent that it took millions of years before any large amounts of biodiversity occurred again. This is why it is also referred to as the ‘Great Dying’. This paper will will analyze the survivability of terrestrial

Geographical location Antarctica is one of the two continents that are wholly in the southern hemisphere. 42 % of Antarctica is owned by Australia, the other 58% is spread across six other countries. All seven countries have agreed to the Antarctic Treaty, which makes laws to prevent pollution and other bad things. Antarctica’s
Cold Environments as Fragile Environments Cold environments such as Western Antarctica (including peninsula) and Arctic tundra are extremely fragile, mainly due to the low temperatures severely limiting vegetation growth and thus any development will destroy the natural environment. Although this fragility of the environment has not deterred development despite the difficulty and cost of developing cold environments, this is due to human’s inability to look to the long-term effects of their
Environmental Impact of Tourism on Antarctica This essay discusses the environmental impact of tourism on Antarctica. The subheading Description will give an overview of the continent, highlight the unique landscape, weather patterns and research stations making up some of the tourist attractions of this continent. The subheading Tourism in Antarctica gives an account of the type of tourist Antarctica attracts and their primary motive identifying scientific research staff as tourists as well
significant impacts to the Polar Regions. Marine and terrestrial fauna at the earth’s polar regions are negatively impacted by global climate change due to the increase in temperatures most of which are now listed as endangered species due to the destruction of their habitat and alteration of their food web. The earth’s polar regions are the ice-covered areas located at the northern and southern ends of the globe known as the Arctic and Antarctica respectively. Life in these regions are incredibly difficult
Brasiliano orogeny and found to be in the southern hemisphere between at about the same time of formation (Trompette, 2000). Gondwana was built of almost all of the landmass, nowadays found in southern hemisphere containing Africa, Australia, Antarctica, South America, Madagascar, Arabian Peninsula and India subcontinent. The later two landmasses mentioned have moved into the northern hemisphere. Furthermore, Florida and most of Central America, southern Europe and much of south-central and southeastern

Steve had no educational qualifications in wildlife conservation, he worked at the Beerwah Reptile and Fauna Park his parents opened in 1970 and after his parents went into retirement he laboured endlessly to develop and expand the park. In 1998 Steve renamed the park Australian Zoo and it soon became a famous tourist attraction (www.australiazoo.com.au)
The culture of Argentina reflects deeply upon the geography. Like all countries, Argentina’s culture is widely influenced by her immigrants. The immigrants consist vastly of European with Amerindian and African persuasion in their music and art. The capital of Argentina, Buenos Aires, is a cultural melting pot filled with exotic traditions that are plainly evident throughout today’s Argentinean society. Argentineans are a mix between native Latin Americans and European immigrant. The European culture
I. Introduction to Argentinosaurus The Argentinosaurus, translated to the Argentine lizard, was believed to be 130 feet long and weighed a whopping 110 tons. It had a 35 to 45 foot long neck with a head size of about 4 to 5 basketballs. The Argentinosaurus was discovered in 1993 by Guillermo Heredia. It was unearthed in present-day Argentina, and is also named after this South American country. Scientists have not yet found the complete skeleton of the Argentinosaurus. Paleontologists found 4 foot
sustain the lives and prevent the extinction of these animals. Preservation of the Galapagos Islands, including protection against invasive species, climate change, and over exploitation, is necessary to conserve the biodiversity of the unique and rare fauna that is indigenous to the Galapagos Islands. The broad biodiversity of the archipelago is under threat and it is essential that preservation of the islands be imposed. Biodiversity is important in any environment, because it boosts the productiveness
to stop global warming. The essay will also review the impact of global warming and community of Nations on tourism and how the changing weather patterns have impacted on the tourism trends from the human perspective as well as from the flora and fauna perspective. This will show how global warming has affected the community and nations negatively and what measures should be taken to stop global warming. Literature Review and Analysis Admin (2011) defines global warming as the increase in the average
Africa. It represent one of the most economically important mammal species and has therefore been introduced into new ecosystems by humans all over the world. Today the European rabbit can be found, in the wild, on every continent except Asia and Antarctica. They are raised extensively worldwide for meat, skin and wool production, as well as being a popular game animal. Furthermore, they make attractive pets due to their easy maintenance and gentle nature and are also widely used in medical research
The Arctic Tundra The Tundra is located in the northern regions of North America, Europe, Asia, as well as a few regions of Antarctica. The Tundra is the second largest vegetation zone in Canada. It can be divided clearly into three different sections: the High Arctic Tundra, the Low Arctic Tundra and the Alpine Tundra. The latter Alpine Tundra occurs in higher altitudes such as mountains whereas the first two are mainly based in plains and lowlands of some kind. The Low Arctic Tundra is
Dear Diary, Today, I investigated the freezing cold tundra biome. The ones I’m investigating are the Arctic and Alpine. The Arctic extremely cold environment with barren landscape. The Arctic’s climate is cold and unforgiving. The average summer temperature is 3-12C, and the average winter temperature is -34 C. Its covering consists of a permanently frozen layer of subsoil, known are permafrost. The soil there is very saturated. As for precipitation, it usually gets 15-25 cm of rain. The Alpine
Introduction: Human activities have led to an exponential increase in the use of fossil fuel. The benefits of using fossil fuels are short lived in comparison to its long-term negative effects. In the last couple of decades, the major consumption of fossil fuel played a significant role in the rise of concentration of CO2 in the atmosphere. Roughly two trillion metric tons of CO2 have been emitted in the atmosphere and over a quarter of these got mixed with the ocean water resulting in ocean acidification
ORDOVICIAN PERIOD The Ordovician Period is the second period of the Paleozoic Era and began 485.4 million years ago and ended 443.4 million years ago (when the Silurian Period began). Four continents were present and separated by three main oceans. Laurentia was composed of present-day North America, part of Scotland, and Greenland and was near the equator. Siberia-Kazakhstan was east of Laurentia, slightly north of the equator. The Iapetus Ocean separated these two masses on the south from the

The Life and Contribution to the Development of the British Empire of James Cook I) Introduction The purpose of this paper is to describe the life and the contribution to the development of the British Empire of one of the most important English explorers. It was in the second half of the 18th century when James Cook, originally a poor farm boy, explored and mapped vast uncharted areas of the Pacific and the Atlantic Ocean. However, James Cook was not ‘only’ an explorer. He can also be called
