Adélie Penguin
The Adélie penguin (''Pygoscelis adeliae'') is a species of penguin common along the entire coast of the Antarctic continent, which is the only place where it is found. It is the most widespread penguin species, and, along with the emperor penguin, is the most southerly distributed of all penguins. It is named after Adélie Land, in turn named for Adèle Dumont d'Urville, who was married to French explorer Jules Dumont d'Urville, who first discovered this penguin in 1840. Adélie penguins obtain their food by both predation and foraging, with a diet of mainly krill and fish. Taxonomy and systematics The first Adélie penguin specimens were collected by crew members of French explorer Jules Dumont d'Urville on his expedition to Antarctica in the late 1830s and early 1840s. Jacques Bernard Hombron and Honoré Jacquinot, two French surgeons who doubled as naturalists on the journey, described the bird for science in 1841, giving it the scientific name ''Catarrhactes adeliæ' ...

Grand Fleet
The Grand Fleet was the main battlefleet of the Royal Navy during the First World War. It was established in August 1914 and disbanded in April 1919. Its main base was Scapa Flow in the Orkney Islands. History Formed in August 1914 from the First Fleet and part of the Second Fleet of the Home Fleets, the Grand Fleet included 25–35 modern capital ships. It was commanded initially by Admiral Sir John Jellicoe.Heathcote, p. 130 The 10th Cruiser Squadron carried out the Northern Patrol between the Shetlands and Norway and cruisers from Cromarty and Rosyth operated a second line (and screened the fleet) in enforcing the blockade of Germany. The administrative complications of the distant blockade across the northern exits of the North Sea overwhelmed the capacity of Vice Admiral Francis Miller, the Base Admiral in Chief from 7 August 1914, devolving on the commander in chief, Admiral John Jellicoe. To relieve the administrative burdens on Miller and Jellicoe, the post of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blubber
Blubber is a thick layer of vascularized adipose tissue under the skin of all cetaceans, pinnipeds, penguins, and sirenians. Description Lipid-rich, collagen fiber-laced blubber comprises the hypodermis and covers the whole body, except for parts of the appendages. It is strongly attached to the musculature and skeleton by highly organized, fan-shaped networks of tendons and ligaments, can comprise up to 50% of the body mass of some marine mammals during some points in their lives, and can range from thick in dolphins and smaller whales, to more than thick in some bigger whales, such as right and bowhead whales. However, this is not indicative of larger whales' ability to retain heat better, as the thickness of a whale's blubber does not significantly affect heat loss. More indicative of a whale's ability to retain heat is the water and lipid concentration in blubber, as water reduces heat-retaining capacities, and lipid increases them. Function Blubber is the primary fat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apsley Cherry-Garrard
Apsley George Benet Cherry-Garrard (2 January 1886 – 18 May 1959) was an English explorer of Antarctica. He was a member of the ''Terra Nova'' expedition and is acclaimed for his 1922 account of this expedition, '' The Worst Journey in the World''. Early life Born in Bedford, as Apsley George Benet Cherry, the eldest child of Apsley Cherry of Denford Park and his wife, Evelyn Edith (née Sharpin), daughter of Henry Wilson Sharpin of Bedford. He was educated at Winchester College and at Christ Church, Oxford where he read classics and modern history. While at Oxford, he rowed in the 1908 Christ Church crew which won the Grand Challenge Cup at the Henley Royal Regatta. His surname was changed to Cherry-Garrard by the terms of his great-aunt's will, through which his father inherited the Lamer Park estate near Wheathampstead, Hertfordshire. Apsley inherited the estate on his father's death in 1907. Cherry-Garrard had always been enamoured of the stories of his father's ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing ...

Animal Sexual Behavior
Animal sexual behaviour takes many different forms, including within the same species. Common mating or reproductively motivated systems include monogamy, polygyny, polyandry, polygamy and promiscuity. Other sexual behaviour may be reproductively motivated (e.g. sex apparently due to duress or coercion and situational sexual behaviour) or non-reproductively motivated (e.g. homosexual sexual behaviour, bisexual sexual behaviour, cross-species sex, sexual arousal from objects or places, sex with dead animals, etc.). When animal sexual behaviour is reproductively motivated, it is often termed ''mating'' or ''copulation''; for most non-human mammals, mating and copulation occur at oestrus (the most fertile period in the mammalian female's reproductive cycle), which increases the chances of successful impregnation. Some animal sexual behaviour involves competition, sometimes fighting, between multiple males. Females often select males for mating only if they appear strong ...

Homosexual Behavior In Birds
Various non-human animal species exhibit behavior that can be interpreted as homosexual or bisexual. This may include same-sex sexual activity, courtship, affection, pair bonding, and parenting among same-sex animal pairs.Braithwaite, L. W., "Ecological studies of the Black Swan III – Behaviour and social organization", ''Australian Wildlife Research'' 8, 1981: 134–146 * Various forms of this are found in every major geographic region and every major animal group. The sexual behavior of non-human animals takes many different forms, even within the same species, though homosexual behavior is best known from social species. Scientists perceive homosexual behavior in animals to different degrees. According to Bruce Bagemihl, same-sex behavior (comprising courtship, sexual, pair-bonding, and parental activities) has been documented in over 450 species of animals worldwide. Although same-sex interactions involving genital contact have been reported in hundreds of animal species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
