Charles S. Elton
Charles Sutherland Elton (29 March 1900 – 1 May 1991) was an English zoologist and animal ecologist. He is associated with the development of population and community ecology, including studies of invasive organisms. Personal life Charles Sutherland Elton was born in Manchester, a son of the literary scholar Oliver Elton and the children's writer Letitia Maynard Elton (''née'' MacColl). He had an older brother, Geoffrey Elton, who died at 33, and to whom Charles Elton in many of his writings attributes his interest in scientific natural history. Charles Elton married the English poet Edith Joy Scovell in 1937, a first five-year marriage to Rose Montague having ended in amicable divorce. Charles and Joy had two children, Catherine Ingrid Buffonge MBE and Robert Elton. Professional life Charles Elton was educated at Liverpool College and Oxford University, from which he graduated in zoology in 1922, with a first in his field research project and a third in the exams, and whe ...

Vertebrates
Vertebrates () comprise all animal taxa within the subphylum Vertebrata () ( chordates with backbones), including all mammals, birds, reptiles, amphibians, and fish. Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 69,963 species described. Vertebrates comprise such groups as the following: * jawless fish, which include hagfish and lampreys * jawed vertebrates, which include: ** cartilaginous fish (sharks, rays, and ratfish) ** bony vertebrates, which include: *** ray-fins (the majority of living bony fish) *** lobe-fins, which include: **** coelacanths and lungfish **** tetrapods (limbed vertebrates) Extant vertebrates range in size from the frog species ''Paedophryne amauensis'', at as little as , to the blue whale, at up to . Vertebrates make up less than five percent of all described animal species; the rest are invertebrates, which lack vertebral columns. The vertebrates traditionally include the hagfish, which do no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic
The Arctic ( or ) is a polar regions of Earth, polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), Finland, Iceland, Norway, Russia (Murmansk Oblast, Murmansk, Siberia, Nenets Autonomous Okrug, Nenets Okrug, Novaya Zemlya), Sweden and the United States (Alaska). Land within the Arctic region has seasonally varying snow and sea ice, ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic. De ...

Spitsbergen
Spitsbergen (; formerly known as West Spitsbergen; Norwegian: ''Vest Spitsbergen'' or ''Vestspitsbergen'' , also sometimes spelled Spitzbergen) is the largest and the only permanently populated island of the Svalbard archipelago in northern Norway. Constituting the westernmost bulk of the archipelago, it borders the Arctic Ocean, the Norwegian Sea, and the Greenland Sea. Spitsbergen covers an area of , making it the largest island in Norway and the 36th-largest in the world. The administrative centre is Longyearbyen. Other settlements, in addition to research outposts, are the Russian mining community of Barentsburg, the research community of Ny-Ålesund, and the mining outpost of Sveagruva. Spitsbergen was covered in of ice in 1999, which was approximately 58.5% of the island's total area. The island was first used as a whaling base in the 17th and 18th centuries, after which it was abandoned. Coal mining started at the end of the 19th century, and several permanent commun ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liverpool College
Liverpool College is a school in Mossley Hill, Liverpool, England. It was one of the thirteen founding members of the Headmasters' Conference (HMC). History Liverpool College was the first of many public schools founded in the Victorian Era. The foundation stone of the original building was laid on 22 October 1840 by Edward Smith-Stanley, 14th Earl of Derby K.G. (then styled the Rt. Hon. Lord Stanley MP), the first patron of the college. A group of Christian Liverpool citizens, many of whose names are now famous in the annals of the city, then began the building of a school where education might be combined with 'sound religious knowledge'. The original building in Shaw street (now apartments) is in the so-called Tudor-Gothic style. It was designed by Mr. Harvey Lonsdale Elmes, and was erected at a cost of £35,000. The college was opened on 6 January 1843 by the Right Hon. William Ewart Gladstone (afterwards four time Prime Minister of the United Kingdom) and the same ...

Oliver Elton
Oliver Elton, FBA (3 June 1861 – 4 June 1945) was an English literary scholar whose works include ''A Survey of English Literature (1730–1880)'' in six volumes, criticism, biography, and translations from several languages including Icelandic and Russian. He was King Alfred Professor of English at Liverpool University. He also helped set up the Department of English at the University of the Punjab, Lahore, Pakistan. Early life Born at Holt, Norfolk, on 3 June 1861, Elton was the only child of Sarah and the Reverend Charles Allen Elton (1820–1887), the headmaster of Gresham's School, where Oliver was taught by his father until he proceeded to Marlborough College and Corpus Christi College, Oxford, where he was a scholar from 1880 to 1885.

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Community Ecology
In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage. The term community has a variety of uses. In its simplest form it refers to groups of organisms in a specific place or time, for example, "the fish community of Lake Ontario before industrialization". Community ecology or synecology is the study of the interactions between species in communities on many spatial and temporal scales, including the distribution, structure, abundance, demography, and interactions between coexisting populations. The primary focus of community ecology is on the interactions between populations as determined by specific genotypic and phenotypic characteristics. Community ecology also takes into account abiotic factors that influence species distributions or interactions (e.g. annual temperat ...
