Endemic Flora Of Western Australia
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eudicots Of Western Australia
The eudicots, Eudicotidae, or eudicotyledons are a clade of flowering plants mainly characterized by having two seed leaves upon germination. The term derives from Dicotyledons. Traditionally they were called tricolpates or non-magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots. Numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Some common and familiar eudicots include sunflower, dandelion, forget-me-not, cabbage, apple, buttercup, maple, and macadamia. Most leafy trees of midlatitudes also belong to eudicots, with notable exceptions being magnolias and tulip trees which belong to magnoliids, and ''Ginkgo biloba'', which is not an angiosperm.

Petrophile
''Petrophile'' is a genus of evergreen shrubs, in the family Proteaceae. The genus is endemic (ecology), endemic to Australia. Commonly known as conebushes, they typically have prickly, divided foliage and produce prominently-displayed pink, yellow or cream flowers followed by grey, conical fruits. Taxonomy The genus ''Petrophile'' was first formally described in 1809 by Joseph Knight (gardener), Joseph Knight in ''On the cultivation of the plants belonging to the natural order of Proteeae'', preempting publication of the same name by Robert Brown (botanist, born 1773), Robert Brown in his book ''On the natural order of plants called Proteaceae''. The name ''Petrophile'' is derived from the Greek words ''petra'' = rock and ''philos'' = seeking or preferring, referring to the rocky habitat in which some species grow. Species list The following is a list of ''Petrophile'' species and subspecies accepted by the Australian Plant Census as at November 2020: *''Petrophile acicular ...

Australia Post
Australia Post, formally the Australian Postal Corporation, is the government business enterprise that provides postal services in Australia. The head office of Australia Post is located in Bourke Street, Melbourne, which also serves as a post office. Australia Post is the successor of the Postmaster-General's Department, which was established at federation in 1901 as the successor to colonial post services. In 1975, the department was abolished and its postal functions were taken over by the Australian Postal Commission. The organisation's current name and structure were adopted in 1989 as part of a process of corporatisation. History Colonial Australia (pre―1901) Before colonial control of mail started in 1809, mail was usually passed on by ad hoc arrangements made between transporters, storekeepers and settlers. These arrangements were flexible, and inherently unstable. It was common for early settlers to ride many miles out of their way to deliver neighbours' mail t ...

Department Of Environment And Conservation (Western Australia)
The Department of Environment and Conservation (DEC) was a department of the Government of Western Australia that was responsible for implementing the state's conservation and environment legislation and regulations. It was formed on 1 July 2006 by the amalgamation of the Department of Environment and the Department of Conservation and Land Management. The DEC was separated on 30 June 2013 forming the Department of Parks and Wildlife (DPaW) and the Department of Environment Regulation (DER), which both commenced operations on 1 July 2013. On 1 July 2017 the DER amalgamated with the Department of Water and the Office of the Environmental Protection Authority, to become the Department of Water and Environmental Regulation, while DPaW was merged with other agencies to form the Department of Parks and Wildlife. Status (at dissolution, 30 June 2013) The department was managing more than 285,000 km2, including more than nine per cent of WA's land area: its national parks, mar ...

Declared Rare And Priority Flora List
The Declared Rare and Priority Flora List is the system by which Western Australia's conservation flora are given a priority. Developed by the Government of Western Australia's Department of Environment and Conservation, it was used extensively within the department, including the Western Australian Herbarium. The herbarium's journal, ''Nuytsia'', which has published over a quarter of the state's conservation taxa, requires a conservation status to be included in all publications of new Western Australian taxa that appear to be rare or endangered. The system defines six levels of priority taxa: ;X: Threatened (Declared Rare Flora) – Presumed Extinct Taxa: These are taxa that are thought to be extinct, either because they have not been collected for over 50 years despite thorough searching, or because all known wild populations have been destroyed. They have been declared as such in accordance with the Wildlife Conservation Act 1950, and are therefore afforded legislative protecti ...

IBRA
The Interim Biogeographic Regionalisation for Australia (IBRA) is a biogeographic regionalisation of Australia developed by the Australian government's Department of Sustainability, Environment, Water, Population, and Communities. It was developed for use as a planning tool, for example for the establishment of a national reserve system. The first version of IBRA was developed in 1993–94 and published in 1995. Within the broadest scale, Australia is a major part of the Australasia biogeographic realm, as developed by the World Wide Fund for Nature. Based on this system, the world is also split into 14 terrestrial habitats, of which eight are shared by Australia. The Australian land mass is divided into 89 bioregions and 419 subregions. Each region is a land area made up of a group of interacting ecosystems that are repeated in similar form across the landscape. IBRA is updated periodically based on new data, mapping improvements, and review of the existing scheme. The most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laterite
Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry periods. Tropical weathering (''laterization'') is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils. The majority of the land area containing laterites is between the tropics of Cancer and Capricorn. Laterite has commonly been referred to as a soil type as well as being a rock type. This and further variation in the modes of conceptualizing about laterite (e.g. also as a complete weathering profile or theory about weathering) has led to calls for the term to be abandoned alto ...

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 ...

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
