Ceriops Australis
''Ceriops australis'', the yellow mangrove or smooth-fruited yellow mangrove, is a species of mangrove in the family Rhizophoraceae, native to tropical northern Australia and southern New Guinea. It is a common species in the region and although mangroves are threatened by habitat destruction and climate change, the International Union for Conservation of Nature has assessed its conservation status as being of "least concern". Description ''Ceriops australis'' is a small evergreen tree or shrub growing to a maximum height of about . The growth habit is columnar or multi-stemmed and it develops large buttress roots. The bark is silvery-grey to orangeish-brown, smooth with occasional lenticels. The leaves are in opposite pairs, glossy yellowish-green above, obovate with entire margins, up to long and wide. The flowers are borne singly in the leaf axils; each has a short calyx tube and parts in fives or sixes. The fruit is pear-shaped, suspended from the shrunken calyx tube. Brow ...

Cyril Tenison White
Cyril Tenison ("C.T.") White (17 August 1890 – 15 August 1950) was an Australian botanist. Early life White was born in Brisbane to Henry White, a trade broker, and Louisa ''nee'' Bailey. He attended school at South Brisbane State School, and was appointed pupil-assistant to the Colonial Botanist of Queensland in 1905, a position previously held by his grandfather on his mother's side, Frederick Manson Bailey. White also succeeded his uncle, John Frederick Bailey, in becoming Queensland's Government Botanist in 1917. Personal life White married Henrietta Duncan Clark, a field naturalist and avid hiker, at South Brisbane on 21 October 1921. They married in Baptist tradition. Career As the Government Botanist, White aided farmers and naturalists in identifying noxious weeds and evaluating native species for pastures and fodder. Between 1915 and 1926, he worked on a 42-part series on weeds which appeared in the ''Queensland Agricultural Journal''. His books, ''An Elementary Tex ...

Lenticel
A lenticel is a porous tissue consisting of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of dicotyledonous flowering plants. It functions as a pore, providing a pathway for the direct exchange of gases between the internal tissues and atmosphere through the bark, which is otherwise impermeable to gases. The name lenticel, pronounced with an , derives from its lenticular (lens-like) shape. The shape of lenticels is one of the characteristics used for tree identification. Evolution Before there was much evidence for the existence and functionality of lenticels, the fossil record has shown the first primary mechanism of aeration in early vascular plants to be the stomata. However, in woody plants, with vascular and cork cambial activity and secondary growth, the entire epidermis may be replaced by a suberized periderm or bark in which the functions of the stomata are replaced by lenticels.

Salt Pan (geology)
Natural salt pans or salt flats are flat expanses of ground covered with salt and other minerals, usually shining white under the sun. They are found in deserts and are natural formations (unlike salt evaporation ponds, which are artificial). A salt pan forms by evaporation of a water pool, such as a lake or pond. This happens in climates where the rate of water evaporation exceeds the rate of that is, in a desert. If the water cannot drain into the ground, it remains on the surface until it evaporates, leaving behind minerals precipitated from the salt ions dissolved in the water. Over thousands of years, the minerals (usually salts) accumulate on the surface. These minerals reflect the sun's rays (through radiation) and often appear as white areas. Salt pans can be dangerous. The crust of salt can conceal a quagmire of mud that can engulf a truck. The Qattara Depression in the eastern Sahara Desert contains many such traps which served as strategic barriers during World ...

Moreton Bay
Moreton Bay is a bay located on the eastern coast of Australia from central Brisbane, Queensland. It is one of Queensland's most important coastal resources. The waters of Moreton Bay are a popular destination for recreational anglers and are used by commercial operators who provide seafood to market. The Port of Brisbane coordinates large traffic along the shipping channel which crosses the northern section of the bay. The bay serves as a safe approach to the airport and reduces noise pollution over the city to the west of the runway. A number of barge, ferry and water-taxi services also travel over the bay. Moreton Bay was the site of conflict between the Quandamooka people and early European settlers. It contains environmentally significant habitats and large areas of sandbanks. The bay is the only place in Australia where dugong gather into herds. Many parts of the mainland foreshore and southern islands are settled. The waters of Moreton Bay are relatively calm, being s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exmouth, Western Australia
Exmouth is a town on the tip of the North West Cape and on Exmouth Gulf in Western Australia, north of the state capital Perth and southwest of Darwin. The town was established in 1967 to support the nearby United States Naval Communication Station Harold E. Holt. It is named after Exmouth Gulf. Beginning in the late 1970s, the town began hosting United States Air Force personnel assigned to Learmonth Solar Observatory, a defence science facility jointly operated with Australia's Ionospheric Prediction Service. The town is served by Learmonth Airport. History In 1618, Dutch East India Company ship ''Mauritius'', under command of Willem Janszoon, landed near North West Cape, just proximate to what would be Exmouth, and named Willem's River, which was later renamed Ashburton River. The location was first used as a military base in World War II. US Admiral James F. Calvert in his memoir, '' Silent Running: My Years on a World War II Attack Submarine'', and US Vice Admiral ...

Viviparous
Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a reproductive mode in which females lay developing eggs that complete their development and hatch externally from the mother. The term 'viviparity' and its adjective form 'viviparous' derive from the Latin ''vivus'' meaning "living" and ''pario'' meaning "give birth to". Reproductive mode Five modes of reproduction have been differentiated in animals based on relations between zygote and parents. The five include two nonviviparous modes: ovuliparity, with external fertilisation, and oviparity, with internal fertilisation. In the latter, the female lays zygotes as eggs with a large yolk; this occurs in all birds, most reptiles, and some fishes. These modes are distinguished from viviparity, which covers all the modes that result in live birth: *Histotrophic viviparity: the zygotes develop in the female's oviducts, but find their nutrients by oophagy ...

Hypocotyl
The hypocotyl (short for "hypocotyledonous stem", meaning "below seed leaf") is the stem of a germinating seedling, found below the cotyledons (seed leaves) and above the radicle (root). Eudicots As the plant embryo grows at germination, it sends out a shoot called a radicle that becomes the primary root, and then penetrates down into the soil. After emergence of the radicle, the hypocotyl emerges and lifts the growing tip (usually including the seed coat) above the ground, bearing the embryonic leaves (called cotyledons), and the plumule that gives rise to the first true leaves. The hypocotyl is the primary organ of extension of the young plant and develops into the stem. Monocots The early development of a monocot seedling like cereals and other grasses is somewhat different. A structure called the coleoptile, essentially a part of the ''cotyledon'', protects the young stem and plumule as growth pushes them up through the soil. A mesocotyl—that part of the young plant that li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calyx (flower)
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Least-concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...
