Grevillea Divaricata
''Grevillea divaricata'' is a possibly extinct species of flowering plant in the family Proteaceae and is endemic to central New South Wales. It is a low shrub with linear leaves and small clusters of flowers on the ends of branchlets. It is only known from the type specimen, discovered in 1823. No live specimens have been found since then. Description ''Grevillea divaricata'' is a shrub that typically grows to a height of up to about and sometimes forms a lignotuber. It has spreading, linear leaves, long and wide with the edges rolled under, obscuring the lower surface. The upper surface of the leaves is rough to the touch. The flowers are arranged on the ends of branches in loose clusters of up to four on a glabrous rachis long, the pistil about long. The flowers are probably red or red and cream-coloured. Flowering was recorded in April. This grevillea is similar to '' G. rosmarinifolia'' but has spreading (rather than erect) leaves, rough (rather than mostly smooth) ...

Proteaceae
The Proteaceae form a family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genera with about 1,660 known species. Together with the Platanaceae and Nelumbonaceae, they make up the order Proteales. Well-known genera include ''Protea'', ''Banksia'', ''Embothrium'', ''Grevillea'', ''Hakea'' and ''Macadamia''. Species such as the New South Wales waratah (''Telopea speciosissima''), king protea (''Protea cynaroides''), and various species of ''Banksia'', ''soman'', and ''Leucadendron'' are popular cut flowers. The nuts of ''Macadamia integrifolia'' are widely grown commercially and consumed, as are those of Gevuina avellana on a smaller scale. Australia and South Africa have the greatest concentrations of diversity. Etymology The name Proteaceae was adapted by Robert Brown from the name Proteae coined in 1789 for the family by Antoine Laurent de Jussieu, based on the genus ''Protea'', which in 1767 Carl Linnaeus derived from t ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Proteales Of Australia
Proteales is an order of flowering plants consisting of three (or four) families. The Proteales have been recognized by almost all taxonomists. The representatives of the Proteales are very different from each other. The order contains plants that do not look alike at all. What they have in common is seeds with little or no endosperm. The ovules are often atropic. Families In the classification system of Dahlgren the Proteales were in the superorder Proteiflorae (also called Proteanae). The APG II system of 2003 also recognizes this order, and places it in the clade eudicots with this circumscription: * order Proteales :* family Nelumbonaceae :* family Proteaceae family Platanaceae">Platanaceae.html" ;"title=" family Platanaceae"> family Platanaceae with "+ ..." = optionally separate family (that may be split off from the preceding family). The APG III system of 2009 followed this same approach, but favored the narrower circumscription of the three families, firmly reco ...

Grevillea
''Grevillea'', commonly known as spider flowers, is a genus of about 360 species of evergreen flowering plants in the family Proteaceae. Plants in the genus ''Grevillea'' are shrubs, rarely trees, with the leaves arranged alternately along the branches, the flowers zygomorphic, arranged in racemes at the ends of branchlets, and the fruit a follicle that splits down one side only, releasing one or two seeds. Description Plants in the genus ''Grevillea'' are shrubs, rarely small trees with simple or compound leaves arranged alternately along the branchlets. The flowers are zygomorphic and typically arranged in pairs along a sometimes branched raceme at the ends of branchlets. The flowers are bisexual, usually with four tepals in a single whorl. There are four stamens and the gynoecium has a single carpel. The fruit is a thin-walled follicle that splits down only one side, releasing one or two seeds before the next growing season. Taxonomy The genus ''Grevillea'' was first forma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodiversity Conservation Act 2016 (NSW)
The ''Biodiversity Conservation Act 2016'' (''BC Act'') is a state-based act of parliament in New South Wales (NSW). Its long title is ''An Act relating to the conservation of biodiversity; and to repeal the Threatened Species Conservation Act 1995, the Nature Conservation Trust Act 2001 and the animal and plant provisions of the National Parks and Wildlife Act 1974''. It supersedes the ''Threatened Species Conservation Act 1995'', and commenced on 25 August 2017. The purpose of the Act was to effect biodiversity reform in New South Wales, in particular to provide better environmental outcomes and reduce burdensome regulations. The Act lists many more purposes under the rubric of "ecologically sustainable development" than the former Act, and specifically mentions "biodiversity conservation in the context of a changing climate". and since mid-2019, the BC Act is administered by the NSW Department of Planning, Industry and Environment The New South Wales Department of Pl ...

Stochastic Process
In probability theory and related fields, a stochastic () or random process is a mathematical object usually defined as a family of random variables. Stochastic processes are widely used as mathematical models of systems and phenomena that appear to vary in a random manner. Examples include the growth of a bacterial population, an electrical current fluctuating due to thermal noise, or the movement of a gas molecule. Stochastic processes have applications in many disciplines such as biology, chemistry, ecology, neuroscience, physics, image processing, signal processing, control theory, information theory, computer science, cryptography and telecommunications. Furthermore, seemingly random changes in financial markets have motivated the extensive use of stochastic processes in finance. Applications and the study of phenomena have in turn inspired the proposal of new stochastic processes. Examples of such stochastic processes include the Wiener process or Brownian motion process, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Regime
A fire regime is the pattern, frequency, and intensity of the bushfires and wildfires that prevail in an area over long periods of time. It is an integral part of fire ecology, and renewal for certain types of ecosystems. A fire regime describes the spatial and temporal patterns and ecosystem impacts of fire on the landscape, and provides an integrative approach to identifying the impacts of fire at an ecosystem or landscape level.Morgan, Penelope; Hardy; Swetnam; Rollins; Long (1999)"Mapping fire regimes across time and space: Understanding coarse and fine-scale fire patterns"(PDF). ''International Journal of Wildland Fire''. 10: 329–342 – via Google Scholar. If fires are too frequent, plants may be killed before they have matured, or before they have set sufficient seed to ensure population recovery. If fires are too infrequent, plants may mature, senesce, and die without ever releasing their seed. Fire regimes can change with the spatial and temporal variations in topography, ...

Type Specimen
In biology, a type is a particular wiktionary:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
