Calamanthus Campestris
The rufous fieldwren (''Calamanthus campestris'') also known as the desert wren or sandplain wren is a species of insectivorous bird in the family Acanthizidae, endemic to Australia. Taxonomy The rufous fieldwren is one of 63 species of the Australasian warbler family Acanthizidae, which includes gerygones, scrubwrens and thornbills. Subspecies ''Calamanthus campestris'' includes the following subspecies: * ''C. c. winiam'' - (Campbell, AJ. & Campbell, AG., 1927) from southeastern Australian mallee. * ''C. c. campestris'' - (Gould, 1841) from southern South Australia and Nullarbor Plain. * ''C. c. rubiginosus'' - (Campbell, AJ., 1899) * ''C. c. dorrie'' - (Mathews, 1912) * ''C. c. hartogi'' - (Carter, 1916) * ''C. c. wayensis'' - (Mathews, 1912) * ''C. c. isabellinus'' - (North, 1896) * ''C. c. montanellus'' (Milligan, 1903) There is both historical and contemporary contention to ''Calamanthus campestris montanellus''' split from a subspecies of the rufous fieldwren t ...

John Gould
John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist. He published a number of monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. He has been considered the father of bird study in Australia and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, ''On the Origin of Species''. Early life Gould was born in Lyme Regis, the first son of a gardener. Both father and son probably had little education. After working on Dowager Lady Poulett's glass house, his father obtained a position on an estate near Guildford, Surrey, and then in 1818, Gould Snr became foreman in the Royal Gardens of Windsor. Gould then be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inland Thornbill
The inland thornbill (''Acanthiza apicalis'') was originally described by English ornithologist John Gould in '' The Birds of Australia.'' Inland thornbills are within the order passerines. The inland thornbill belongs to the genus '' Acanthiza,'' which now has three more species than the eleven outlined by Gould in The Birds of Australia. The ''Noongar'' people of southwestern Western Australia call ''A. apicalis'' "Djoobi-Djoolbang". The inland thornbill is also known as the broad-tail thornbill and presently contains several subspecies that were once considered independent species. The word ''apicalis'' comes from the Latin for 'tipped'. Taxonomy and evolution Early classification of the ''Acanthiza'', or thornbill genus, was inconsistent with the currently accepted taxonomy. Historically, researchers recognised 10 -17 species in 1 – 3 genera. Separate traditional species of Thornbill have now been more accurately classified as subspecies than discrete species; howeve ...

Chenopod
Amaranthaceae is a family of flowering plants commonly known as the amaranth family, in reference to its type genus ''Amaranthus''. It includes the former goosefoot family Chenopodiaceae and contains about 165 genera and 2,040 species, making it the most species-rich lineage within its parent order, Caryophyllales. Description Vegetative characters Most species in the Amaranthaceae are annual or perennial herbs or subshrubs; others are shrubs; very few species are vines or trees. Some species are succulent. Many species have stems with thickened nodes. The wood of the perennial stem has a typical "anomalous" secondary growth; only in subfamily Polycnemoideae is secondary growth normal. The leaves are simple and mostly alternate, sometimes opposite. They never possess stipules. They are flat or terete, and their shape is extremely variable, with entire or toothed margins. In some species, the leaves are reduced to minute scales. In most cases, neither basal nor terminal aggrega ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-arid Climate
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSk'' and ''BSh'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as it usually can't support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): *multiply by ...

Arid
A region is arid when it severely lacks available water, to the extent of hindering or preventing the growth and development of plant and animal life. Regions with arid climates tend to lack vegetation and are called xeric or desertic. Most arid climates straddle the Equator; these regions include parts of Africa, Asia, South America, North America, and Australia. Change over time The distribution of aridity at any time is largely the result of the general circulation of the atmosphere. The latter does change significantly over time through climate change. For example, temperature increase by 1.5–2.1 percent across the Nile Basin over the next 30–40 years could change the region from semi-arid to arid, significantly reducing the land usable for agriculture. In addition, changes in land use can increase demands on soil water and thereby increase aridity.

Allocasuarina Humilis
''Allocasuarina humilis'', commonly known as the dwarf sheoak or dwarf casuarina, is a woody shrub of the family Casuarinaceae endemic to the south-west of Western Australia. Description Unlike many sheoaks which grow into trees, ''Allocasuarina humilis'' only reaches 20 cm to 2 m (8–80 in) in height. A many branched shrub, its branchlets ascend from larger branches and reach 12 cm (5 in) in length. As with other sheoaks, its foliage consists of slender green branchlets informally referred to as "needles" but more correctly termed cladodes. The cladodes are segmented, and the true leaves are tiny teeth encircling each joint. It can be dioecius or monecious. The reddish-brown male flower spikes are between 6 and 18 mm long and the warty cones are cylindrical, about 12 to 22 mm in length and 10 to 17 mm in diameter. Taxonomy Originally described as ''Casuarina humilis'' by German naturalists Christoph Friedrich Otto and Albert Gottfried Dietri ...

Melaleuca
''Melaleuca'' () is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles or tea-trees (although the last name is also applied to species of '' Leptospermum''). They range in size from small shrubs that rarely grow to more than high, to trees up to . Their flowers generally occur in groups, forming a "head" or "spike" resembling a brush used for cleaning bottles, containing up to 80 individual flowers. Melaleucas are an important food source for nectarivorous insects, birds, and mammals. Many are popular garden plants, either for their attractive flowers or as dense screens and a few have economic value for producing fencing and oils such as "tea tree" oil. Most melaleucas are endemic to Australia, with a few also occurring in Malesia. Seven are endemic to New Caledonia, and one is found only on (Australia's) Lord Howe Island. Melaleucas are found in a wide variety of habitats. Many are adapted for life in swamp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Maireana Sedifolia
''Maireana sedifolia'', also known as the bluebush or pearl bluebrush is a compact shrub endemic to Australia, and found in New South Wales, Victoria, South Australia, Western Australia, and the Northern Territory. It is used in pasture and as a garden plant where it is popular due to its distinctive grey foliage. It was first described in 1855 by Ferdinand von Mueller as ''Kochia sedifolia'', but was reassigned to the genus, ''Maireana ''Maireana '' is a genus of around 57 species of perennial shrubs and herbs in the family Amaranthaceae which are endemic to Australia. Species in this genus were formerly classified within the genus ''Kochia''. The genus was described in 1840 b ...,'' by Paul Wilson in 1975.

Nullarbor Plain
The Nullarbor Plain ( ; Latin: feminine of , 'no', and , 'tree') is part of the area of flat, almost treeless, arid or semi-arid country of southern Australia, located on the Great Australian Bight coast with the Great Victoria Desert to its north. It is the world's largest single exposure of limestone bedrock, and occupies an area of about . At its widest point, it stretches about from east to west across the border between South Australia and Western Australia. History Historically, the Nullarbor was seasonally occupied by Indigenous Australian people, the Mirning clans and Yinyila people. Traditionally, the area was called ''Oondiri'', which is said to mean "the waterless". The first Europeans known to have sighted and mapped the Nullarbor coast were Captain François Thijssen and Councillor of the Indies, Pieter Nuyts, on the Dutch East Indiaman '''t Gulden Zeepaert'' (the Golden Seahorse). In 1626–1627, they charted a stretch of the southern Australian coast eas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperate Climate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...
