Zephyrarchaea Mainae
''Zephyrarchaea mainae'' is a species of spider, informally known as Main's assassin spider, Albany assassin spider, and the Western archaeid spider. The first of the assassin spider family (Araneae, Archaeidae) found in Western Australia, the species was unknown until its collection at Torndirrup National Park near Albany was published in 1987. Taxonomy Formally described as ''Austrarchaea mainae'' by Norman Platnick in 1991, the spider was nominated as the type species for the Australian endemic genus ''Zephyrarchaea''. This split from the more widely distributed ''Austrarchaea'' was published in 2012, after further specimens were found and collected in nearby areas, along with several other related archaeid species discovered in the region. Comparative analysis of genotyped archaeid species supports the spider's classification as a species, as does the restricted mobility and specialised habitat of populations.

South Coast Of Western Australia
The south coast of Western Australia comprises the Western Australian coastline from Cape Leeuwin to Eucla. This is a distance of approximately , fronting the Great Australian Bight and the Southern Ocean. Components The Bureau of Meteorology in forecast districts break up the south coast into four sub-regions: * Leeuwin coast (Cape Naturaliste to Walpole) * Albany coast (Walpole to Bremer Bay) * Esperance coast (Bremer Bay to Israelite Bay) * Eucla coast (Israelite Bay to Eucla) With other authorities and departments, the region is usually broken up into smaller regions, oriented to the Great Southern regional centre of Albany and, further east, Esperance. However, some sources apply "south coast" from Windy Harbour to Mount Manypeaks as the delineating points for the coast. Rainbow Coast The Rainbow Coast is a tourist region name for the coast as well. It is called the Rainbow Coast because of the fast-moving weather fronts that buffet the coast from th ...

Spiders Described In 1991
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate ...

Empodisma Gracillimum
''Empodisma gracillimum'' is a species of sedge-like plant endemic to coastal areas of Southwest Australia. Described within an Australian and New Zealand genus of the rush- or bamboo-like Restionaceae family, it is the only species of '' Empodisma'' to be found in Western Australia. A perennial herb, growing to a height between 0.2 and 1.2 metres, found near winter wet ground and permanent waterways. The inflorescence is brown, appearing between July and December or January and February. The preferred soil type is grey to black sand and peat. The habit of the species is to cluster together, the leaves becoming an entangled barrier that inspired the Greek derivation of the genus and its common name of wire rush. The rhizomatous roots form dense mats that retain water, the detritus of the plant assemblage creating a peat habitat that is also occupied by bryophytes. The species was formerly named ''Calorophus gracillimum'', by Ferdinand von Mueller, until the erection of a new ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepidosperma Effusum
''Lepidosperma effusum'', commonly known as the riverside sword sedge or spreading sword sedge, is an evergreen species of sedge that is native to southwest Western Australia. Description The sedge has a robust and tufted habit typically growing in clumps to a height of and a width of . It is rhizome, rhizomatous and confined to damp areas. It flowers between April and November producing brown coloured flowers. Taxonomy The species was first formally described by English botanist George Bentham in his ''Flora Australiensis'' in 1878. Distribution It occurs along the edges of creeks and streams and around swamps from the Perth region south through the Margaret River region and eastwards to Albany where it grows in sandy or loamy soils. Ecology ''L. effusum'' occupies a hygrophilous ecological niche along with other Lepidosperma species; ''Lepidosperma australe, L.australe'', ''Lepidosperma longitudinale, L. longitudinale'', ''Lepidosperma gladiatum, L. gladiatum'' , ''Lepidosp ...

Karri Forest
Karri forest is a tall open forest type dominated by ''Eucalyptus diversicolor'' (karri), one of the tallest hardwoods in the world. Karri forest occurs only in the south-west corner of the Southwest Botanical Province of Western Australia, in the Warren biogeographic region.Marchant, N. G. (2000) ''Karri forest in microcosm : William Bay National Park.'' Landscope (Como, W.A), Spring 2000, p. 42-47 The Warren region is also known as the Karri Forest Region, but this is a misnomer, as only about half of the region is vegetated with karri forest. From the 1880s onward, karri forest supported timber and firewood industries when access to the forest was improved by a network of the state's railway lines. Small settlements such as Karridale, Deanmill and Pemberton were established around timber mills, and have since become centres for regional tourism. Some of the remaining areas of karri forest are now protected in reserves such as Brockman National Park, Warren National ...

Agonis Flexuosa
''Agonis flexuosa'' is a species of tree that grows in the south west of Western Australia. It is easily the most common of the ''Agonis'' species, and is one of the most recognisable trees of Western Australia, being commonly grown in parks and on road verges in Perth. The species is commonly known as Western Australian peppermint, Swan River peppermint or peppermint, and willow myrtle for its weeping habit. The Noongar peoples know the tree as Wanil, Wonnow, Wonong or Wannang. Description ''A. flexuosa'' occurs mainly as a small and robust tree, usually less than 10 metres tall, although it may grow to 15 metres. It has fibrous brown bark, long narrow dull-green leaves, and tightly clustered inflorescences of small white flowers in the axes. It grows in a weeping habit, and looks remarkably like the weeping willow from a distance. Leaves are narrow and reach a length of 150mm. It is most readily identified by the powerful odour of peppermint emitted when the leaves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bremer Bay, Western Australia
Bremer Bay is a coastal town situated on the south coast of Western Australia in the Great Southern region between Albany and Esperance, at the mouth of the Bremer River. Bremer Bay is southeast of the state capital, Perth, and east of Albany. Demographics In 2016 the townsite had a population of 231. Over the 2018 Christmas and New Year holiday period the town's population reached almost 6,500. History The bay was named by John Septimus Roe, who visited the area in 1831, after Sir James Bremer, captain of , under whom he served as a lieutenant from 1824 to 1827. The area was originally settled in the 1850s with the first homestead, the ''Wellstead homestead'' being built in 1857 and the first telegraph station being built in 1875. A second telegraph station was built of stone in 1896 to replace the first one. The town was originally included in the township of Wellstead until a local petition in 1951 favoured a change to the current name, which was approved and gaz ...
