Meade Island
Meade Island is an uninhabited sand island located about 200 metres from Dirk Hartog Island in the Shark Bay World Heritage Site in Western Australia, and joined to that island at low tide. It has an area of about 800 square metres (0.2 acre), and an elevation of two metres (7 ft). The island's vegetation is a closed heath, of which the dominant plant species are ''Nitraria billardierei'' (Nitre Bush), '' Scaevola crassifolia'' (Thick-leaved Fan-flower) and ''Spinifex longifolius'' (Beach Spinifex). Other plant species include '' Exocarpos aphyllus'' (Leafless Ballart), ''Rhagodia preissii'' subsp. ''obovata'', '' Salsola tragus'' (Prickly Saltwort), ''Sonchus oleraceus'' (Common Sow-thistle), and a species of ''Pelargonium''. Eight species of seabird roost on the island.

Salsola Tragus
is a species of flowering plant in the family Amaranthaceae. It is known by various common names such as prickly Russian thistle, windwitch, or common saltwort. It is widely known simply as tumbleweed because in many regions of the United States, it is the most common and most conspicuous plant species that produces tumbleweeds. Informally, it also is known as "'salsola", which was its generic name until 2007. For a brief phase during its youth, it may be grazed but afterwards becomes too spiny and woody to be edible to most wildlife and livestock (if it is not processed first). Mature specimens are often more than a meter in diameter. As its fruits mature, the diaspore of the plant dies, dries, hardens, and detach from its root. This detached anatomical part of is called a tumbleweed, which is why is colloquially called "tumbleweed" (although there are many other plant species that also produce tumbleweeds). Once mature, dry, and detached from the plant, this tumbleweed wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seabird
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely. Seabirds and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelargonium
''Pelargonium'' () is a genus of flowering plants that includes about 280 species of perennials, succulents, and shrubs, commonly called geraniums, pelargoniums, or storksbills. '' Geranium'' is also the botanical name and common name of a separate genus of related plants, also known as cranesbills. Both genera belong to the family Geraniaceae. Carl Linnaeus originally included all the species in one genus, ''Geranium'', and they were later separated into two genera by Charles Louis L'Héritier de Brutelle in 1789. While ''Geranium'' species are mostly temperate herbaceous plants, dying down in winter, ''Pelargonium'' species are evergreen perennials indigenous to warm temperate and tropical regions of the world, with many species in southern Africa. They are drought and heat tolerant, but can tolerate only minor frosts. Some species are extremely popular garden plants, grown as houseplants and bedding plants in temperate regions. They have a long flowering period, with flowers m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sonchus Oleraceus
''Sonchus oleraceus'' is a species of flowering plant in the tribe Cichorieae of the family Asteraceae, native to Europe and Western Asia.

Rhagodia Preissii Subsp
''Chenopodium'' is a genus of numerous species of perennial or annual herbaceous flowering plants known as the goosefoots, which occur almost anywhere in the world. It is placed in the family Amaranthaceae in the APG II system; older classification systems, notably the widely used Cronquist system, separate it and its relatives as Chenopodiaceae, but this leaves the rest of the Amaranthaceae polyphyletic. However, among the Amaranthaceae, the genus ''Chenopodium'' is the namesake member of the subfamily Chenopodioideae. Description The species of ''Chenopodium'' (s.str., description according to Fuentes et al. 2012) are annual or perennial herbs, shrubs or small trees. They generally rely on alkaline soil. They are nonaromatic, but sometimes fetid. The young stems and leaves are often densely covered by vesicular globose hairs, thus looking farinose. Characteristically, these trichomes persist, collapsing later and becoming cup-shaped. The branched stems grow erect, ascendin ...

Shark Bay, Western Australia
Shark Bay (Malgana: ''Gathaagudu'', "two waters") is a World Heritage Site in the Gascoyne region of Western Australia. The http://www.environment.gov.au/heritage/places/world/shark-bay area is located approximately north of Perth, on the westernmost point of the Australian continent. UNESCO's official listing of Shark Bay as a World Heritage Site reads: : History The record of Australian Aboriginal occupation of Shark Bay extends to years BP. At that time most of the area was dry land, rising sea levels flooding Shark Bay between BP and BP. A considerable number of aboriginal midden sites have been found, especially on Peron Peninsula and Dirk Hartog Island which provide evidence of some of the foods gathered from the waters and nearby land areas. An expedition led by Dirk Hartog happened upon the area in 1616, becoming the second group of Europeans known to have visited Australia. (The crew of the ''Duyfken'', under Willem Janszoon, had visited Cape York in 1606). T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
