Murray Darling Depression
The Murray Darling Depression , also known as the Murray-Darling woodlands and mallee, is a 19,717,651 HA biogeographic region and an ecoregion in southeastern Australia consisting of a wooded plain through which flow two of Australia's biggest rivers, the Murray and the Darling. There are several modern human settlements in the bioregion including Ivanhoe and Manilla, but the region also contains some of the oldest known human occupation sites in Australia. Environment The plains have a dry Mediterranean climate with more rainfall (400mm per year) in the south than in the drier north (250mm). Fires are common in the hot dry summers. Wetlands The depression is home to numerous wetlands which are in turn home to many rare and endangered animal and plant species. Major wetlands within the bioregion include the Darling Anabranch Lakes, Conoble Lake, Lake Victoria, Willandra lakes, and Gunnaramby Swamp. Flora The original vegetation of the basin was mallee eucalyptus woodlan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Desert National Park
The Little Desert National Park is a national park in the Wimmera Mallee region of Victoria, Australia. The national park is situated near Dimboola, approximately west of Melbourne and extends from the Wimmera River in the east to the South Australian border in the west near . While the region is surrounded by agricultural land, the area of the Little Desert itself "consists mainly of deep sandy soils with very low fertility, interspersed with small pockets of clay soils. There are occasional rocky, sandstone outcrops and buckshot rises. Average yearly rainfall varies remarkably from the east to the west." The Little Desert "remains relatively undisturbed by human activity, even though in the earlier years of European settlement it experienced some industry in the way of grazing and woodcutting." Now the desert is a National Park, and is "broken up into three blocks": Western Block, Central Block and Eastern Block; demarcated by two north-south roads, the Nhill-Harrow road ...

Manilla, New South Wales
Manilla is a small town in New South Wales, Australia, located on Fossickers Way 45 kilometres northwest of the regional city of Tamworth and 27 kilometres northeast of the historic village Somerton. Manilla is famous for its setting as a fishing and paragliding area. The name Manilla comes from the Gamilaraay language, and is said to mean 'winding river'. Manilla was established in the 1850s at the junction of the Namoi River and the Manilla River. It was formerly the centre of Manilla Shire local government area, but this was amalgamated with Tamworth City Council and portions of Parry, Barraba and Nundle Shire Councils to form Tamworth Regional Council in 2004. It lies next to the Bundarra-Barraba Important Bird Area which is important for the conservation of the critically endangered regent honeyeater. Manilla is also well known for Split Rock Dam on the Manilla River and Lake Keepit on the Namoi River. Services *Bowling Club *Caravan Park *Royal Hotel *Ambles ...

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. Oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meliphaga
''Meliphaga'' is a genus of birds in the honeyeater family Meliphagidae. The genus was introduced by the English artist John Lewin in 1808. The name ''Meliphaga'' combines the Ancient Greek meaning "honey" and meaning eating. The type species is Lewin's honeyeater (''Meliphaga lewinii''). The genus contains three species: * Puff-backed honeyeater (''Meliphaga aruensis'') * Yellow-spotted honeyeater (''Meliphaga notata'') * Lewin's honeyeater (''Meliphaga lewinii'') The genus formerly included additional species.

Lichenostomus
''Lichenostomus'' is a genus of honeyeaters endemic to Australia. The genus formerly contained twenty species but it was split after a molecular phylogenetic analysis published in 2011 showed that the genus was polyphyletic. Former members were moved to the six new genera: ''Nesoptilotis'', ''Bolemoreus'', ''Caligavis'', ''Stomiopera'', ''Gavicalis'' and '' Ptilotula''. The genus contains two species: The name ''Lichenostomus'' was introduced by the German ornithologist Jean Cabanis in 1851.

Honeyeater
The honeyeaters are a large and diverse family, Meliphagidae, of small to medium-sized birds. The family includes the Australian chats, myzomelas, friarbirds, wattlebirds, miners and melidectes. They are most common in Australia and New Guinea, and found also in New Zealand, the Pacific islands as far east as Samoa and Tonga, and the islands to the north and west of New Guinea known as Wallacea. Bali, on the other side of the Wallace Line, has a single species. In total there are 186 species in 55 genera, roughly half of them native to Australia, many of the remainder occupying New Guinea. With their closest relatives, the Maluridae (Australian fairy-wrens), Pardalotidae (pardalotes), and Acanthizidae (thornbills, Australian warblers, scrubwrens, etc.), they comprise the superfamily Meliphagoidea and originated early in the evolutionary history of the oscine passerine radiation. Although honeyeaters look and behave very much like other nectar-feeding passerines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relict Population
In biogeography and paleontology, a relict is a population or taxon of organisms that was more widespread or more diverse in the past. A relictual population is a population currently inhabiting a restricted area whose range was far wider during a previous geologic epoch. Similarly, a relictual taxon is a taxon (e.g. species or other lineage) which is the sole surviving representative of a formerly diverse group. Definition A relict (or relic) plant or animal is a taxon that persists as a remnant of what was once a diverse and widespread population. Relictualism occurs when a widespread habitat or range changes and a small area becomes cut off from the whole. A subset of the population is then confined to the available hospitable area, and survives there while the broader population either shrinks or evolves divergently. This phenomenon differs from endemism in that the range of the population was not always restricted to the local region. In other words, the species or group did ...

Eriocaulon Australasicum
''Eriocaulon australasicum'' (common names southern pipewort, austral pipewort) is an endangered monocotyledonous plant in the Eriocaulaceae family found in Australia, in Victoria, South Australia and New South Wales. Description ''Eriocaulon australasicum'' is a small, annual, semi-aquatic herb with a tuft of basal linear leaves which are 20–50 mm long by 1–1.5 mm wide. The flowers occur as egg-shaped to almost globular heads 3–4 mm wide. These are enclosed in lance-shaped outer bracts and by linear inner bracts. The fruits are smooth, with three celled capsules, which each contain a single seed. It possibly requires an inundation period to enable germination from soil-stored seed. Plants start to grow in shallow water (up to 20 cm deep), particularly when the water is clear and the substrate has high organic content. Flowering and seed-set swiftly follow falling water levels and the drying-out of depressions. Little is known about seed set, seed bank accumulation and ...

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 b ...

Mallee (habit)
Mallee are trees or shrubs, mainly certain species of eucalypts, which grow with multiple stems springing from an underground lignotuber, usually to a height of no more than . The term is widely used for trees with this growth habit across southern Australia, in the states of Western Australia, South Australia, New South Wales and Victoria, and has given rise to other uses of the term, including the ecosystems where such trees predominate, specific geographic areas within some of the states and as part of various species' names. Etymology The word is thought to originate from the word ''mali'', meaning water, in the Wemba Wemba language, an Aboriginal Australian language of southern New South Wales and Victoria. The word is also used in the closely related Woiwurrung language and other Aboriginal languages of Victoria, South Australia, and southern New South Wales.
