Acacia Carneorum
''Acacia carneorum'', also referred to as purple-wood wattle, needle wattle, dead finish or by its former scientific name, ''Acacia carnei'', is a plant species in the genus '' Acacia''. It occurs in small populations in far north-west New South Wales and South Australia. Purple-wood wattle is a threatened shrub, listed as vulnerable under the Environmental Protection and Biodiversity Conservation Act (EPBC Act), NSW Threatened Species Conservation Act 1995 and South Australia National Parks and Wildlife Act 1992. Description The wattle is distinctly known for its deep-purple heartwood. However, once cut and left exposed to air for a few weeks, the purple turns near black. From the exterior, the wattle is a dark green, prickly shrub to small tree that can grow 2–4 m high and up to 8m wide. The growth rate is very slow in mature plants, shown through photo points of over 30 years. The prickly appearance of the shrub refers to the pointy phyllodes (leaves), which are rigid, str ...

Joseph Maiden
Joseph Henry Maiden (25 April 1859 – 16 November 1925) was a botanist who made a major contribution to knowledge of the Australian flora, especially the genus ''Eucalyptus''. This botanist is denoted by the author abbreviation when citing a botanical name. Life Joseph Maiden was born in St John's Wood in northwest London. He studied science at the University of London, but due to ill health he did not complete the course. As part of his treatment he was advised to take a long sea voyage, and so in 1880 he sailed for New South Wales. In 1881, Maiden was appointed first curator of the Technological Museum in Sydney (now the Powerhouse Museum), remaining there until 1896. While there, he published an article in 1886 describing what he called "some sixteenth century maps of Australia". These were the so-called Dieppe maps, the Rotz (1547), the Harleian or Dauphin (mid-1540s), and the Desceliers (1550), photo-lithographic reproductions of which had been published by the Briti ...

Rabbit
Rabbits, also known as bunnies or bunny rabbits, are small mammals in the family Leporidae (which also contains the hares) of the order Lagomorpha (which also contains the pikas). ''Oryctolagus cuniculus'' includes the European rabbit species and its descendants, the world's 305 breeds of domestic rabbit. ''Sylvilagus'' includes 13 wild rabbit species, among them the seven types of cottontail. The European rabbit, which has been introduced on every continent except Antarctica, is familiar throughout the world as a wild prey animal and as a domesticated form of livestock and pet. With its widespread effect on ecologies and cultures, the rabbit is, in many areas of the world, a part of daily life—as food, clothing, a companion, and a source of artistic inspiration. Although once considered rodents, lagomorphs like rabbits have been discovered to have diverged separately and earlier than their rodent cousins and have a number of traits rodents lack, like two extra incis ...

Plants Described In 1916
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

Polyploid
Polyploidy is a condition in which the cells of an organism have more than one pair of ( homologous) chromosomes. Most species whose cells have nuclei ( eukaryotes) are diploid, meaning they have two sets of chromosomes, where each set contains one or more chromosomes and comes from each of two parents, resulting in pairs of homologous chromosomes between sets. However, some organisms are polyploid. Polyploidy is especially common in plants. Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Males of bees and other Hymenoptera, for example, are monoploid. Unlike animals, plants and multicellular algae have life cycles with two alternating multicellular generations. The gametophyte generation is haploid, and produces gametes by mitosis, the sporophyte generation is diploid and produces spores by ...

Darling River
The Darling River ( Paakantyi: ''Baaka'' or ''Barka'') is the third-longest river in Australia, measuring from its source in northern New South Wales to its conflu ence with the Murray River at Wentworth, New South Wales. Including its longest contiguous tributaries it is long, making it the longest river system in Australia. The Darling River is the outback's most famous waterway. The Darling is in poor health, suffering from over-allocation of its waters to irrigation, pollution from pesticide runoff, and prolonged drought. During drought periods in 2019 it barely flowed at all. The river has a high salt content and declining water quality. Increased rainfall in its catchment in 2010 improved its flow, but the health of the river will depend on long-term management. The Division of Darling, Division of Riverina-Darling, Electoral district of Darling and Electoral district of Lachlan and Lower Darling were named after the river.

Joseph Carne
Joseph Carne (17 April 1782 – 12 October 1858) was a British geologist and industrialist. Early life Carne was born at Penzance, Cornwall, United Kingdom, the eldest son of William Carne, a banker, and his wife Anna Carne née Cock of Helston. He was educated at home and at the Wesleyan school, Keynsham, near Bristol. One of his four younger brothers was the author and traveller John Carne. From an early age Carne showed an interest in mineralogy and geology. He was in the habit of walking round to the copper mines, and collecting specimens of the rarer ores, which the miners were glad to sell at low prices, thereby forming the nucleus of his mineralogical collection. On 23 March 1808 he married Mary Thomas, the daughter of William Thomas of Kidwelly, MD, physician at Haverfordwest. After his marriage he lived for a short time at Penzance, and in 1808 he removed to Rivière House, Phillack on being appointed manager of the Cornish Copper Company's smelting works at Hayle. ...

Flavonoid
Flavonoids (or bioflavonoids; from the Latin word ''flavus'', meaning yellow, their color in nature) are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans. Chemically, flavonoids have the general structure of a 15-carbon skeleton, which consists of two phenyl rings (A and B) and a heterocyclic ring (C, the ring containing the embedded oxygen). This carbon structure can be abbreviated C6-C3-C6. According to the IUPAC nomenclature, they can be classified into: *flavonoids or bioflavonoids *isoflavonoids, derived from 3-phenyl chromen-4-one (3-phenyl-1,4-benzopyrone) structure *neoflavonoids, derived from 4-phenylcoumarine (4-phenyl-1,2-benzopyrone) structure The three flavonoid classes above are all ketone-containing compounds and as such, anthoxanthins ( flavones and flavonols). This class was the first to be termed bioflavonoids. The terms flavonoid and bioflavonoid have also been more loosely used to describe non ...

Ringbarking
Girdling, also called ring-barking, is the complete removal of the bark (consisting of cork cambium or "phellogen", phloem, cambium and sometimes going into the xylem) from around the entire circumference of either a branch or trunk of a woody plant. Girdling results in the death of the area above the girdle over time. A branch completely girdled will fail and when the main trunk of a tree is girdled, the entire tree will die, if it cannot regrow from above to bridge the wound. Human practices of girdling include forestry, horticulture, and vandalism. Foresters use the practice of girdling to thin forests. Animals such as rodents will girdle trees by feeding on outer bark, often during winter under snow. Girdling can also be caused by herbivorous mammals feeding on plant bark and by birds and insects, both of which can effectively girdle a tree by boring rows of adjacent holes. Orchardists use girdling as a cultural technique to yield larger fruit or to set fruit. In vinic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollinator
A pollinator is an animal that moves pollen from the male anther of a flower to the female stigma of a flower. This helps to bring about fertilization of the ovules in the flower by the male gametes from the pollen grains. Insects are the major pollinators of most plants, and insect pollinators include all families of bees and most families of aculeate wasps; ants; many families of flies; many lepidopterans (both butterflies and moths); and many families of beetles. Vertebrates, mainly bats and birds, but also some non-bat mammals (monkeys, lemurs, possums, rodents) and some lizards pollinate certain plants. Among the pollinating birds are hummingbirds, honeyeaters and sunbirds with long beaks; they pollinate a number of deep-throated flowers. Humans may also carry out artificial pollination. A pollinator is different from a pollenizer, a plant that is a source of pollen for the pollination process. Background Plants fall into pollination syndromes that reflect the type o ...

Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen record ...
