Ancient Greenling
''Hemiphlebia mirabilis'', commonly known as the ancient greenling, is a species of damselfly, the only living species of the genus ''Hemiphlebia'' and the family Hemiphlebiidae. It is very small with a long, metallic-green body and clear wings. It is endemic to south-eastern Australia. Its natural swamp habitat is threatened by habitat loss. The oldest representatives of the family date to the Late Jurassic. Distribution and habitat The ancient greenling has been recorded from a small number of scattered sites, including on King Island and in Mount William, Tasmania; in Wilsons Promontory National Park and near Yea, Victoria; and in Piccaninnie Ponds Conservation Park in south-eastern South Australia. Its recorded habitat includes permanent freshwater ponds, riverine lagoons and swamps that may dry out seasonally. A favoured site discovered in 2008, Long Swamp in the Discovery Bay Coastal Park of south-western Victoria, contains extensive areas of twig-rush ('' Baumea'' sp.) ...

Yea, Victoria
Yea ( ) is a town in Victoria (Australia), Victoria, Australia north-east of the state capital Melbourne at the junction of the Goulburn Valley Highway and the Melba Highway, in the Shire of Murrindindi local government area. In an area originally inhabited by the Taungurung people, it was first visited by Europeans of the Hume and Hovell expedition in 1824, and within 15 years most of the land in the area had been taken up by graziers. Surveyed in 1855, the township grew as a service centre for grazing, gold-mining and timber-getting in the area. The town has had a fairly stable population (around 1,100) since 1900, though it now has a relatively old population. The town economy is based around servicing the farming sector, and tourism, with good road links but little public transport. The town has education supplied by three schools (state primary and high schools, and a Catholic primary). It has three churches, and active sporting clubs. Heritage sites around the town includ ...

Insects Described In 1869
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues.

Taxa Named By Edmond De Sélys Longchamps
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Australia
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Endangered Fauna Of Australia
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct.

The blood therefore does not carry oxygen; it is only partly contained in vessels, and some circulates in an open hemocoel. Insect vision is mainly through their compound eyes, with additional small ocelli. Many insects can hear, using tympanal organs, which may be on the legs or other parts of the body. Th ...

Odonata Of Australia
Odonata is an order of predatory flying insects that includes the dragonflies and damselflies (as well as the '' Epiophlebia'' damsel-dragonflies). The two major groups are distinguished with dragonflies (Anisoptera) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies (suborder Zygoptera) are usually more slender with eyes placed apart and wings folded together along body at rest. Adult odonates can land and perch, but rarely walk. All odonates have aquatic larvae called naiads or nymphs, and all of them, larvae and adults, are carnivorous and are almost entirely insectivorous, although at the larval stage they will eat anything that they can overpower, including small fish, tadpoles, and even adult newts. The adults are superb aerial hunters and their legs are specialised for catching prey in flight. Odonata in its narrow sense forms a subgroup of the broader Odonatoptera, which contains other dragonfly-like insects. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. In 2012 there were 5,196 animals and 6,789 plants classified as vulnerable, compared with 2,815 and 3,222, respectively, in 1998. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A taxon ...

Baumea
''Baumea'' is a genus of the sedge family, which includes around 30 species native to Madagascar and the Pacific Islands, with 15 species in Australia. All are perennial rhizomatous herbs, with leaves and stems very similar in appearance. The inflorescence is terminal, with the flowers tightly clustered or loosely arranged. The fruits are small nuts. It is closely related to the genus ''Machaerina'', and is sometimes included in that genus. Habitat and cultivation Most species occur in open moist habitats; many are found in swamps or seasonally inundated areas. ''Baumea'' is propagated from transplants, divisions, or from seeds, which germinate readily if sown on damp organic mix and kept moist until shoots appear.

Discovery Bay Coastal Park
The Discovery Bay Coastal Park is a linear protected area of coastal land in western Victoria, south-eastern Australia. The park extends along the coast of Discovery Bay from Cape Nelson north-westwards for to the border with South Australia. The park was listed on Australia's now-defunct Register of the National Estate, and lies within the traditional lands of the Gunditjmara people. Part of the route of the Great South West Walk is located within the park. The Discovery Bay Marine National Park adjoins the park to the west of Cape Bridgewater History After being recommended as a coastal reserve in 1973 by Victoria's Land Conservation Council, the park was first included in Schedule 3 of the Victorian National Parks Act in 1979, with an area of . Additional parcels of land were acquired in 1981, 1987 and 1997. Land within the coastal park, the Lower Glenelg National Park and the Nelson Streamside Reserve was listed as a Ramsar site known as the Glenelg Estuary and Dis ...
