Phasianotrochus Apicinus
''Phasianotrochus apicinus'', common name the pointed kelp shell, is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.Marshall, B. (2013). Phasianotrochus apicinus (Menke, 1843). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=719244 on 2014-02-13 Description The height of the shell attains 20 mm. The imperforate, solid, smooth shell has an elongated conical shape. It is shining, grayish, or brownish-yellow, with numerous narrow, fine, crowded, obliquely longitudinal red lines. These are often hard to perceive on account of the golden and violet iridescence. The whole surface is microscopically spirally striate. The striae are coarser on the base. The 8 to 9 whorls are nearly flat. The upper whorls are pink. The acute spire is turreted, and straight sided. The sutures are linear, sometimes with a white margin. The body whorl is rounded at the periphery. The oval aperture i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subtidal Zone
The neritic zone (or sublittoral zone) is the relatively shallow part of the ocean above the drop-off of the continental shelf, approximately in depth. From the point of view of marine biology it forms a relatively stable and well-illuminated environment for marine life, from plankton up to large fish and corals, while physical oceanography sees it as where the oceanic system interacts with the coast. Definition (marine biology), context, extra terminology In marine biology, the neritic zone, also called coastal waters, the coastal ocean or the sublittoral zone, refers to that zone of the ocean where sunlight reaches the ocean floor, that is, where the water is never so deep as to take it out of the photic zone. It extends from the low tide mark to the edge of the continental shelf, with a relatively shallow depth extending to about 200 meters (660 feet). Above the neritic zone lie the intertidal (or eulittoral) and supralittoral zones; below it the continental slope begin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geological Survey Of Western Australia
The Geological Survey of Western Australia is an authority within the Department of Mines and Petroleum of the Government of Western Australia that is responsible for surveying and exploration of Western Australia's geological resources. The department provides information to industry, technical support and professional guidance to government on geology, mining and petroleum resources. Historically the Survey has existed under the various names that the Mines Department has been ascribed by various governments. Mapping The mapping by the survey between 1894 and 2015 is documented in Riganti and others with examples of state maps: - * 1894 - Woodward Map * 1916 - Brockman Map * 1919 and 1920 * 1933 * 1950 * 1966 * 1973 * 1979 * 1988 -- centenary of GSWA * 1998 * 2015 Map Also some sections have moved between the survey and other departments. For example, the hydrogeology section was moved to the Waters and Rivers Commission in 1996.Allen, A.D. (1996) ''A history ...

South Australian Government
The Government of South Australia, also referred to as the South Australian Government, SA Government or more formally, His Majesty’s Government, is the Australian state democratic administrative authority of South Australia. It is modelled on the Westminster system of government, which is governed by an elected parliament. History Until 1857, the Province of South Australia was ruled by a Governor responsible to the British Crown. The Government of South Australia was formed in 1857, as prescribed in its Constitution created by the Constitution Act 1856 (an act of parliament of the then United Kingdom of Great Britain and Ireland under Queen Victoria), which created South Australia as a self-governing colony rather than being a province governed from Britain. Since the federation of Australia in 1901, South Australia has been a state of the Commonwealth of Australia, which is a constitutional monarchy, and the Constitution of Australia regulates the state of South Aust ...

Proceedings Of The Royal Society
''Proceedings of the Royal Society'' is the main research journal of the Royal Society. The journal began in 1831 and was split into two series in 1905: * Series A: for papers in physical sciences and mathematics. * Series B: for papers in life sciences. Many landmark scientific discoveries are published in the Proceedings, making it one of the most historically significant science journals. The journal contains several articles written by the most celebrated names in science, such as Paul Dirac, Werner Heisenberg, Ernest Rutherford, Erwin Schrödinger, William Lawrence Bragg, Lord Kelvin, J.J. Thomson, James Clerk Maxwell, Dorothy Hodgkin and Stephen Hawking. In 2004, the Royal Society began ''The Journal of the Royal Society Interface'' for papers at the interface of physical sciences and life sciences.

Southern Australia
The term Southern Australia is generally considered to refer to the states and territories of Australia of New South Wales, Victoria, Tasmania, the Australian Capital Territory and South Australia. The part of Western Australia south of latitude 26° south a definition widely used in law and state government policy is also usually included. Although it comprises about half of the total area of Australia, Southern Australia includes about three-quarters of the Australian population, the main agricultural areas and the main industrial centres. The area is also notable for its primarily temperate, mediterranean, alpine or arid environmental and climatic conditions which contrasts to the mainly tropical climate of Northern Australia. Southern Australia has long suffered extreme weather events due to the arid landscape, however in recent times these conditions have been exacerbated due to climate change. The region has several key industries which contribute to the high gross ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
