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] |
Myrtaceae
Myrtaceae, the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pÅhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire (i.e., without a toothed margin). The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous. Evolutionary history Scientists hypothesize that the family Myrtaceae arose between 60 and 56 million years ago (Mya) during the Paleocene era. Pollen fossils have been sourced to the ancient supercontinent Gondwana. The breakup of Gondwana during the Cretaceous period (145 to 66 Mya) geographically isolated disjunct taxa and allowed for rapid speciation; i ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gibson Desert
The Gibson Desert is a large desert in Western Australia, largely in an almost "pristine" state. It is about in size, making it the fifth largest desert in Australia, after the Great Victoria, Great Sandy, Tanami and Simpson deserts. The Gibson Desert is both an interim Australian bioregion and desert ecoregion. Location and description The Gibson Desert is located between the saline Kumpupintil Lake and Lake Macdonald along the Tropic of Capricorn, south of the Great Sandy Desert, east of the Little Sandy Desert, and north of the Great Victoria Desert. The altitude rises to just above in places. As noted by early Australian explorers such as Ernest Giles large portions of the desert are characterized by gravel-covered terrains covered in thin desert grasses and it also contains extensive areas of undulating red sand plains and dunefields, low rocky/gravelly ridges and substantial upland portions with a high degree of laterite formation. The sandy soil of the later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Victoria Desert
The Great Victoria Desert is a sparsely populated desert ecoregion and interim Australian bioregion in Western Australia and South Australia. History In 1875, British-born Australian explorer Ernest Giles became the first European to cross the desert. He named the desert after the then-reigning monarch, Queen Victoria. In 1891, David Lindsey's expedition traveled across this area from north to south. Frank Hann was looking for gold in this area between 1903 and 1908. Len Beadell explored the area in the 1960s. Location and description The Great Victoria is the largest desert in Australia, and consists of many small sandhills, grassland plains, areas with a closely packed surface of pebbles (called desert pavement or gibber plains), and salt lakes. It is over wide (from west to east) and covers an area of from the Eastern Goldfields region of Western Australia to the Gawler Ranges in South Australia. The Western Australian mulga shrublands ecoregion lies to the west, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Sandy Desert
The Little Sandy Desert (LSD) is a desert region in the state of Western Australia, lying to the east of the Pilbara and north of the Gascoyne regions. It is part of the Western Desert cultural region, and was declared an interim Australian bioregion in the 1990s. History Indigenous groups that have identified with the region include the Mandilara, an Aboriginal Australian group who are regarded as the traditional owners of the land. Today the group recognised as traditional owners are the Martu people. The desert is crossed by the Canning Stock Route, an historic stock route created in the early 20th century. Description The Little Sandy Desert covers around and adjoins the Great Sandy Desert (, to the north) and the Gibson Desert (, to the east), all of which lie within the huge Australian Arid Zone which covers the centre of the Australian continent.

Flora Of Western Australia
The flora of Western Australia comprises 10,551 published native vascular plant species and a further 1,131 unpublished species. They occur within 1,543 genera from 211 families; there are also 1,317 naturalised alien or invasive plant species more commonly known as weeds. There are an estimated 150,000 cryptogam species or nonvascular plants which include lichens, and fungi although only 1,786 species have been published, with 948 algae and 672 lichen the majority. History Indigenous Australians have a long history with the flora of Western Australia. They have for over 50,000 years obtained detailed information on most plants. The information includes its uses as sources for food, shelter, tools and medicine. As Indigenous Australians passed the knowledge along orally or by example, most of this information has been lost, along many of the names they gave the flora. It was not until Europeans started to explore Western Australia that systematic written details of the flora comme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
