Euastacus Yanga
''Euastacus yanga'', also known as the variable spiny cray, is a freshwater crayfish endemic to south eastern Australia. Description The maximum recorded size was OCL (Occipital Carapace Length) which is used to measure the species' size. The rostrum is short and in individuals over OCL usually does not reach the base of the third antenna segment. In those measuring OCL the rostrum is to the base or midpoint of that segment and, in some under , goes to the end of the third segment. The cephalon is spiny on most organisms but less so on specimens under OCL. In southern populations the spines are larger and more numerous. Their thorax has up to 20 spines on each side in one or two irregular rows although this is usually absent on smaller individuals (under OCL). The spines are generally longer and sharper in southern populations. The tubercles are moderately to densely distributed on specimens over OCL, very sparse to moderately on smaller examples, occasionally absen ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Highlands (New South Wales)
The Southern Highlands, also locally referred to as the Highlands, is a geographical region and district in New South Wales, Australia and is 110 km south-west of Sydney. The entire region is under the local government area of the Wingecarribee Shire. The region is also considered a wine region. The region specifically is the area centred on the commercial towns of Mittagong, Bowral, Moss Vale, Bundanoon and Robertson as well as the historic town of Berrima. Smaller villages like Burradoo, Sutton Forest, Colo Vale, Avoca, Yerrinbool, Exeter, Welby and many more that make up the Wingecarribee Shire are spread in between and around these main centres and serve mostly as residential areas. The Highlands geographically sits between 500 m and 900 m above sea level on the Great Dividing Range. Like other regions along this plateau such as the Blue Mountains to the north and the Australian Alps to the south, the Southern Highlands is known for its cool temperate c ...

Endemic Fauna Of Australia
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crustaceans Described In 1997
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by ...

Freshwater Crustaceans Of Australia
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. ...

Euastacus
''Euastacus'' is a genus of freshwater crayfish known as "spiny crayfish". They are found in the south-east of the Australian mainland, along with another genus of crayfish, ''Cherax''. Both genera are members of the family Parastacidae, a family of freshwater crayfish restricted to the Southern Hemisphere. ''Euastacus'' crayfish are distinguished from the smooth-shelled ''Cherax'' species by the short robust spikes on their claws and carapace, and frequently, their larger size. Many ''Euastacus'' species grow to a relatively large size, with the Murray River crayfish (''Euastacus armatus'') being the second largest freshwater crayfish species in the world. (The largest freshwater crayfish in the world is the Tasmanian giant freshwater crayfish (''Astacopsis gouldi''), found on the Australian island of Tasmania, and the genus ''Astacopsis'' is now known to be a very closely related sister genus to ''Euastacus''.) The genera ''Cherax'' and ''Euastacus'' continue a trend pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sclerophyll
Sclerophyll is a type of vegetation that is adapted to long periods of dryness and heat. The plants feature hard leaf, leaves, short Internode (botany), internodes (the distance between leaves along the stem) and leaf orientation which is parallel or oblique to direct sunlight. The word comes from the Greek ''sklēros'' (hard) and ''phyllon'' (leaf). The term was coined by Andreas Franz Wilhelm Schimper, A.F.W. Schimper in 1898 (translated in 1903), originally as a synonym of xeromorph, but the two words were later differentiated. Sclerophyllous plants occur in many parts of the world, but are most typical of areas with low rainfall or seasonal droughts, such as Australia, Africa, and western North and South America. They are prominent throughout Flora of Australia, Australia, parts of Flora of Argentina, Argentina, the Cerrado biogeographic region of Geography of Bolivia, Bolivia, Geography of Paraguay, Paraguay and Flora of Brazil, Brazil, and in the Mediterranean forests, woo ...

AMSL
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Euastacus Spinifer
''Euastacus spinifer '' is a species of freshwater crayfish endemic to Australia that belongs to the family Parastacidae. Appearance Morphological variation is observed in ''Euastacus spinifer'' that originate in different river systems. They are mostly green with reddish-brown joints and bright spines. Diet Detritus forms the staple diet of the species but they may also eat small invertebrates and tadpoles. They are also cannibalistic Cannibalism is the act of consuming another individual of the same species as food. Cannibalism is a common ecological interaction in the animal kingdom and has been recorded in more than 1,500 species. Human cannibalism is well documented, bo .... They are also believed to be opportunistic omnivore. Life cycle Mating takes place in winter when temperature drops to as low as , and eggs are laid in early July. Eggs are carried in the female Pleopods and hatch after an incubation period of 110–140 days. Hatch-lings stay with their parent ...

Genoa, Victoria
Genoa is a town in Eastern Gippsland, Victoria, Australia. It is close to the New South Wales border where the Princes Highway crosses the Genoa River. The town is an important access point to the Croajingolong National Park. At the 2006 census, Genoa and the surrounding area had a population of 304. The Genoa Post Office opened on 9 April 1888. In 1972 the earliest fossil trackway of primitive tetrapods were found in the Genoa River Gorge, dating back 350 million years. In 2019, bush fires in Eastern Gippsland did "significant" damage to Genoa and the nearby town of Mallacoota Mallacoota is a small town in the East Gippsland region in the state of Victoria, Australia.

Bundanoon, New South Wales
Bundanoon is a town in the Southern Highlands of New South Wales, Australia, in Wingecarribee Shire, on Gandangarra and Dharawal Country (where these two countries meet). It is an Aboriginal name meaning "place of deep gullies" and was formerly known as ''Jordan's Crossing''. Bundanoon is colloquially known as ''Bundy/Bundi''. Bundanoon, like its fellow Southern Villages of the Southern Highlands, has had a boom-and-bust economic cycle. The town became a well-known tourist destination early in the 20th century; its picturesqueness and the scenery of what is now Morton National Park, combined with being served by the railway network, made it a pleasant and convenient holiday area for city dwellers who could not afford more expensive accommodations at the popular Blue Mountains resort area. By the 1950s, however, changes in lifestyle, particularly the affordability of the motor car, gave city dwellers more options and Bundanoon declined. The Sydney real estate boom of the ear ...
