Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

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] |

Coolgardie (biogeographic Region)
Coolgardie is an Australian bioregion consisting of an area of low hills and plains of infertile sandy soil in Western Australia. It has an area of . It includes much of the Great Western Woodlands. Location and description This is a transition zone between the Mediterranean climate of Australia's south-west coast and the country's dry interior. The poor soil makes it unsuitable for agriculture but Coolgardie has been a gold and nickel mining area. It is bounded on the north by the arid Murchison bioregion, characterised by open Mulga woodlands and steppe. The low shrublands of the arid Nullarbor Plain lie to the east. The Mallee bioregion adjoins Coolgardie on the south. The Avon Wheatbelt bioregion is to the west. The Coolgardie bioregion, together with the coastal Hampton bioregion to the southeast, constitute the Coolgardie woodlands ecoregion defined by the World Wildlife Fund.

Avon Wheatbelt
The Avon Wheatbelt is a bioregion in Western Australia. It has an area of . It is considered part of the larger Southwest Australia savanna ecoregion. Geography The Avon Wheatbelt bioregion is mostly a gently undulating landscape with low relief. It lies on the Yilgarn Craton, an ancient block of crystalline rock, which was uplifted in the Tertiary and dissected by rivers. The craton is overlain by laterite deposits, which in places have decomposed into yellow sandplains, particularly on low hills. Steep-sided erosional gullies, known as breakaways, are common.

Zanthus, Western Australia
Zanthus is a remote and uninhabited outpost on the Trans-Australian Railway approximately east of the regional city of Kalgoorlie in the Goldfields–Esperance region of Western Australia. Transport A depot existed at Zanthus prior to 1915 when the east to west section of the Trans Australian Railway was still not completed. Trains were arriving daily at the station in 1915 mostly carrying materials to the railhead from Kalgoorlie. Passengers were stranded at Zanthus in 1948 when a train was delayed resulting from floodwaters causing washaways along the tracks between Zanthus and Kalgoorlie. Several passengers completed the journey to Kalgoorlie via a Goldfield Airways airplane while over 50 men worked to fix the two big washaways. A derailment of a train occurred in 1953 when five coaches of the transcontinental eastbound express left the tracks near the town tearing up a section of the line. Repair crews worked through the night and built a deviation by the following d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norseman, Western Australia
Norseman is a town located in the Goldfields-Esperance region of Western Australia along the Coolgardie-Esperance Highway, east of Perth and above sea level. It is also the starting point of the Eyre Highway, and the last major town in Western Australia before the South Australian border to the east. At the 2021 census, Norseman had a population of 562, of which 17% were Australian Aboriginal. History The quest for gold led to the establishment of Norseman, on the traditional land of the Ngadju. Today there are a number of small goldmining operations in the area but only the Central Norseman Gold Corporation can be considered a major producer. Gold was first found in the Norseman area in 1892, about 10 km south of the town, near Dundas. The "Dundas Field" was proclaimed in August 1893 and a townsite gazetted there. In August 1894, Lawrence Sinclair, his brother George Sinclair, and Jack Alsopp discovered a rich gold reef which Sinclair named after his horse, Hardy Nor ...

Callion, Western Australia
Callion is an abandoned town in the Goldfields-Esperance region in Western Australia. It is between Coolgardie and Leonora, in the Shire of Menzies. Gold was discovered here in 1895 and the town was originally known as Speakman's Find after the prospector who made the original discovery. The lease, owned by Speakman, Cooke and Lukin, was 30 acres in size and contained three reefs. The reefs became the Callion Mine, reportedly named after the local Aboriginal word for quartz, although it has been speculated that it was the name of another prospector, without any evidence. The town was gazetted in 1897. One of the first mines established in the area was the Lady Kate, which was operating in early 1896. A 20 head battery was erected in the town in 1897 and continued to operate until at least 1902. A cemetery is all that is left of the old townsite, which is now part of Credo Station Credo is a former pastoral lease located about north of Coolgardie in the Goldfields of W ...
