Parvotettix
''Parvotettix'' is an extant genus of cave cricket from the order Orthoptera in the family Rhaphidophoridae, endemic to Tasmania, Australia. The genus was established in 1968 by Aola Richards and contains six species she described. ''Parvotettix'' is a sister group to the subfamily Macropathinae, forming a paraphyletic Australian grouping. Habitat ''Parvotettix'' occupy epigean, subterranean habitats. ''Parvotettix'' were initially discovered in limestone caves. Various species within the genus ''Parvotettix'' inhabit environmental structures such as mine adits, large rock crevices, tree logs, caves, burrows created by other animals and within houses. ''Parvotettix'' thrive in dark, moist environments in colder temperatures at sea level. There is no threatening conservation risk associated with ''Parvotettix.'' Environmental factors that increase vulnerability for ''Parvotettix'' include predation by rodents that are introduced to the area, interspecific competition, climat ...

Cave Cricket
The orthopteran family Rhaphidophoridae of the suborder Ensifera has a worldwide distribution. Common names for these insects include cave wētā, cave crickets, camelback crickets, camel crickets, Hogan bugs, spider crickets (sometimes shortened to "criders", or "land shrimp" or "sprickets",) and sand treaders. Those occurring in New Zealand, Australia, and Tasmania are typically referred to as jumping or cave wētā. Most are found in forest environments or within caves, animal burrows, cellars, under stones, or in wood or similar environments. All species are flightless and nocturnal, usually with long antennae and legs. More than 500 species of Rhaphidophoridae are described. The well-known field crickets are from a different superfamily (Grylloidea) and only look vaguely similar, while members of the family Tettigoniidae may look superficially similar in body form. Description Most cave crickets have very large hind legs with "drumstick-shaped" femora and equally long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Seta
In biology, setae (singular seta ; from the Latin word for "bristle") are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Annelid setae are stiff bristles present on the body. They help, for example, earthworms to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (a group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. Crustaceans have mechano- and chemosensory setae. Setae are especially present on the mouthparts of crustaceans and can also be found on grooming limbs. In some cases, setae are modified into scale like structures. Setae on the legs of krill and other small crustaceans help them to gather phytoplankton. It captures them and allow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Furneaux Group
The Furneaux Group is a group of approximately 100 islands located at the eastern end of Bass Strait, between Victoria and Tasmania, Australia. The islands were named after British navigator Tobias Furneaux, who sighted the eastern side of these islands after leaving Adventure Bay in 1773 on his way to New Zealand to rejoin Captain James Cook. Navigator Matthew Flinders was the first European to explore the Furneaux Islands group, in the in 1798, and later that year in the . The largest islands in the group are Flinders Island, Cape Barren Island, and Clarke Island. The group contains five settlements: Killiecrankie, Emita, Lady Barron, Cape Barren Island, and Whitemark on Flinders Island, which serves as the administrative centre of the Flinders Council. There are also some small farming properties on the remote islands. After seals were discovered there in 1798, the Furneaux Group of islands became the most intensively exploited sealing ground in Bass Strait. A tot ...

Cape Barren Island
Cape Barren Island, officially truwana / Cape Barren Island, is a island in the Bass Strait, off the north east coast of Tasmania, Australia. It is the second largest island of the Furneaux Group; Flinders Island lies to the north, with the smaller Clarke Island to the south. The highest point on the island is Mount Munro at . Mount Munro is probably named after James Munro (c. 1779-1845), a former convict and then sealer, who lived from the 1820s for more than 20 years with several women on nearby Preservation Island. The south-eastern point of the island was named ''Cape Barren'' by Tobias Furneaux in in March 1773. The island was gazetted as a locality of the Flinders Council in 1968. The population of the island numbered 66 in 2016, most of them in the settlement Cape Barren Island, also called ''The Corner'', on the northwest coast. Australia's only native goose, the Cape Barren goose, was first documented by European explorers on this island. History Seal ...

Pleistocene
The Pleistocene ( , often referred to as the '' Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the t ...

Flinders Island
Flinders Island, the largest island in the Furneaux Group, is a island in the Bass Strait, northeast of the island of Tasmania. Flinders Island was the place where the last remnants of aboriginal Tasmanian population were exiled by the colonial British government. Today Flinders Island is part of the state of Tasmania, Australia. It is from Cape Portland and is located on 40° south, a zone known as the Roaring Forties. History Prehistory Flinders Island was first inhabited at least 35,000 years ago, when people made their way from Australia across the then land-bridge which is now Bass Strait. A population remained until about 4,500 years ago, succumbing to thirst and hunger following an acute El Niño climate shift. European discovery Some of the south-eastern islands of the Furneaux Group were first recorded in 1773 by British navigator Tobias Furneaux, commander of , the support vessel with James Cook on Cook's second voyage. In February 1798, British navigat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria (state)
Victoria is a state in southeastern Australia. It is the second-smallest state with a land area of , the second most populated state (after New South Wales) with a population of over 6.5 million, and the most densely populated state in Australia (28 per km2). Victoria is bordered by New South Wales to the north and South Australia to the west, and is bounded by the Bass Strait to the south (with the exception of a small land border with Tasmania located along Boundary Islet), the Great Australian Bight portion of the Southern Ocean to the southwest, and the Tasman Sea (a marginal sea of the South Pacific Ocean) to the southeast. The state encompasses a range of climates and geographical features from its temperate coastal and central regions to the Victorian Alps in the northeast and the semi-arid north-west. The majority of the Victorian population is concentrated in the central-south area surrounding Port Phillip Bay, and in particular within the metropolita ...

Wilsons Promontory
Wilsons Promontory, is a peninsula that forms the southernmost part of the Australian mainland, located in the state of Victoria. South Point at is the southernmost tip of Wilsons Promontory and hence of mainland Australia. Located at nearby South East Point, () is the Wilsons Promontory Lighthouse. Most of the peninsula is protected by the Wilsons Promontory National Park and the Wilsons Promontory Marine National Park. Human history Wilsons Promontory was first occupied by indigenous Koori people at least 6,500 years prior to European arrival. Middens along the western coast indicate that the inhabitants subsisted on a seafood diet. The first European to see the promontory was George Bass in January 1798. He initially referred to it as "Furneaux's Land" in his diary, believing it to be what Captain Furneaux had previously seen. But on returning to Port Jackson and consulting Matthew Flinders he was convinced that the location was so different it could not be ...

Gondwana
Gondwana () was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic period (about 180 million years ago). The final stages of break-up, involving the separation of Antarctica from South America (forming the Drake Passage) and Australia, occurred during the Paleogene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it. To differentiate it from the Indian region of the same name (see ), it is also commonly called Gondwanaland. Gondwana was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Palaeozoic Era, covering an area of about , about one-fifth of the Earth's surface. During the Carboniferous Period, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
