Interim Biogeographic Regionalisation For Australia
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] |
Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have been grow ...

Skink
Skinks are lizards belonging to the family Scincidae, a family in the infraorder Scincomorpha. With more than 1,500 described species across 100 different taxonomic genera, the family Scincidae is one of the most diverse families of lizards. Skinks are characterized by their smaller legs in comparison to typical lizards and are found in different habitats except arctic and subarctic regions. Description Skinks look like lizards of the family Lacertidae (sometimes called ''true lizards''), but most species of skinks have no pronounced neck and relatively small legs. Several genera (e.g., ''Typhlosaurus'') have no limbs at all. This is not true for all skinks, however, as some species such as the red-eyed crocodile skink have a head that is very distinguished from the body. These lizards also have legs that are relatively small proportional to their body size. Skinks' skulls are covered by substantial bony scales, usually matching up in shape and size, while overlapping. Other gen ...

Lerista
''Lerista'' is a diverse (~ 90 species) genus of skinks endemic to Australia, commonly known as sliders. The genus is especially notable for the variation in the amount of limb reduction. The variation ranges from short-bodied forms with large legs bearing five toes, to elongate forms completely lacking legs. The body length of the lizards is . Their locomotion is linked to their body shape. The shorter skinks with prominent limbs travel on the surface; the longer skinks with reduced legs tend to burrow more. A phylogenetic tree of ''Lerista'', derived from DNA analysis, reveals that limb loss has happened multiple times within this group. Limb loss has occurred relatively recently, in the past 3.6 million years or so. Species The following species are recognized as being valid. www.reptile-database.org. Note: a binomial authority in parentheses indicates that the species was originally described in a genus other than ''Lerista''. *'' Lerista aericeps'' – desert plain ...

Spectacled Hare-wallaby
The spectacled hare-wallaby (''Lagorchestes conspicillatus'') is a species of macropod found in Australia and New Guinea. In Australia, a small sub-population is found on Barrow Island, while the mainland type is widespread, though in decline, across northern regions of the country. Description A species of ''Lagorchestes'', hare-wallaby are small members of the family Macropodidae. The spectacled hare-wallaby is found across northern Australia in tropical tussock or spinifex habitats. It can be found from Queensland to Western Australia. In 1997, it was discovered in the savanna country of southwest Papua New Guinea, in the upper Bensbach River area. It is a solitary, nocturnal herbivore, and is considerably larger than its relatives. It is coloured grey-brown with golden tips and an orange circle around its eye, from which it gets its name. It builds its nests among the tough vegetation. When disturbed it hops off in a zigzag manner. The young are produced singly at any tim ...

Long-tailed Planigale
The long-tailed planigale (''Planigale ingrami''), also known as Ingram's planigale or the northern planigale, is the smallest of all marsupials, and one of the smallest of all mammals. It is rarely seen but is a quite common inhabitant of the blacksoil plains, clay-soiled woodlands, and seasonally flooded grasslands of Australia's Top End. Taxonomy The long-tailed planigale was described in 1906 by Oldfield Thomas, who placed it in the genus ''Phascogale''. The species was moved in 1928 by Ellis Le Geyt Troughton, who created the genus ''Planigale'' for it and the other then-known species, the common planigale (''P. maculata''), and described the narrow-nosed planigale (''P. tenuirostris''). The species has since suffered some taxonomic confusion, having been referred to as ''Planigale subtilissima''; there has also been some confusion concerning subspecies. Currently, three subspecies are recognised: *''P. i. ingrami'', found in the Northern Territory to Townsville, Queensland; ...

Northern Nail-tail Wallaby
The northern or sandy nail-tail wallaby (''Onychogalea unguifera'') is a species of macropod found across northern Australia on arid and sparsely wooded plains. The largest species of the genus ''Onychogalea'', it is a solitary and nocturnal herbivorous browser that selects its food from a wide variety of grasses and succulent plant material. Distinguished by a slender and long-limbed form that resembles the typical and well known kangaroos, although their standing height is shorter, around half of one metre, and their weight is less than nine kilograms. As with some medium to large kangaroo species, such as ''Osphranter rufus'', they have an unusual pentapedal motion at slow speeds by stiffening the tail for a fifth limb. When fleeing a disturbance, they hop rapidly with the tail curled back and repeatedly utter the sound "wuluhwuluh". Their exceptionally long tail has a broad fingernail-like protuberance beneath a dark crest of hair at its end, a peculiarity of the genus that i ...

Eastern Wallaroo
The common wallaroo (''Osphranter robustus''), also known as the euro, hill wallaroo, or simply wallaroo, is a species of macropod. The word ''euro'' is particularly applied to one subspecies (''O. r. erubescens'').WE Poole and JC Merchant (1987): ''Reproduction in Captive Wallaroos - the Eastern Wallaroo, Macropus-Robustus-Robustus, the Euro, Macropus-Robustus-Erubescens and the Antilopine Wallaroo, Macropus-Antilopinus.'' Australian Wildlife Research 14(3) 225 - 242online link/ref> The eastern wallaroo is mostly nocturnal and solitary, and is one of the more common macropods. It makes a loud hissing noise and some of the other subspecies are sexually dimorphic, like most wallaroos. Subspecies There are four subspecies: *the eastern wallaroo (''O. r. robustus'') – found in eastern Australia; males of this subspecies have dark grey fur, almost resembling the black wallaroo (''Osphranter bernardus''). Females are lighter, being almost sandy in colour. *the euro or western wall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pandanus
''Pandanus'' is a genus of monocots with some 750 accepted species. They are palm-like, dioecious trees and shrubs native to the Old World tropics and subtropics. The greatest number of species are found in Madagascar and Malaysia. Common names include pandan, screw palm, and screw pine. They are classified in the order Pandanales, family Pandanaceae. Description Often called pandanus palms, these plants are not closely related to palm trees. The species vary in size from small shrubs less than tall, to medium-sized trees tall, typically with a broad canopy, heavy fruit, and moderate growth rate. The trunk is stout, wide-branching, and ringed with many leaf scars. Mature plants can have branches. Depending on the species, the trunk can be smooth, rough, or warty. The roots form a pyramidal tract to hold the trunk. They commonly have many thick stilt roots near the base, which provide support as the tree grows top-heavy with leaves, fruit, and branches. These roots are adven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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.

Triodia (plant Genus)
''Triodia'' is a large genus of hummock-forming bunchgrass endemic to Australia. They are known by the common name spinifex, although they are not a part of the coastal genus '' Spinifex''. Many of the soft-leaved members of this species were formerly included in the genus ''Plectrachne''. It is known as ''tjanpi'' in central Australia, and is used for basket weaving by the women of various Aboriginal Australian peoples. A multiaccess key (SpiKey) is available as a free application for identifying the ''Triodia'' of the Pilbara (28 species and one hybrid). Description ''Triodia'' is a perennial Australian tussock grass that grows in arid regions. Its leaves (30–40 centimetres long) are subulate ( awl-shaped, with a tapering point). The leaf tips, that are high in silica, can break off in the skin, leading to infections. Uses Spinifex has traditionally had many uses for Aboriginal Australians. The seeds were collected and ground to make seedcakes. Spinifex resin was a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
