Nobby Islet
Nobby Islet (also known as Knobby Island and Nobby Island) is an islet located in the Great Australian Bight off the south coast of Kangaroo Island in the Australian state of South Australia approximately south-west of Kingscote. It is currently part of the Seal Bay Conservation Park. Description Nobby Islet is approximately south-west of Kingscote and about east of Point Ellen in Vivonne Bay and within of the coast at Seal Bay. The islet is reported as being cylindrical in shape with almost vertical sides and finished with a flat top. It is high and has an area of . The islet is difficult to access due to its location in shallow water adjoining a cliffed coastline that exposed to rolling seas and the fragile condition of its vertical cliff faces. A survey carried out by the responsible government agency in 1996 used a helicopter to access the islet's summit. Formation, geology and oceanography Nobby Islet may have been formed as recently as 6000 years ago due to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Australian Bight
The Great Australian Bight is a large oceanic bight, or open bay, off the central and western portions of the southern coastline of mainland Australia. Extent Two definitions of the extent are in use – one used by the International Hydrographic Organization (IHO) and the other used by the Australian Hydrographic Service (AHS). The IHO defines the Great Australian Bight as having the following limits: ''On the North.'' The south coast of the Australian mainland. ''On the South.'' A line joining West Cape Howe () Australia to South West Cape, Tasmania. ''On the East.'' A line from Cape Otway, Victoria to King Island and thence to Cape Grim, the northwest extreme of Tasmania. The AHS defines the bight with a smaller area, from Cape Pasley, Western Australia, to Cape Carnot, South Australia - a distance of . Much of the bight lies due south of the expansive Nullarbor Plain, which straddles South Australia and Western Australia. The Eyre Highway passes close to the cli ...

Coast Beard-heath
''Leucopogon parviflorus'', commonly known as coast beard-heath or native currant, is a shrub or small tree in the family Ericaceae. It is native to all Australian states and territories excluding the Northern Territory and the ACT and also grows in New Zealand. The species can grow to between 1 and 5 metres in height and has leaves that are 11 to 29 mm long and 2.4 to 7.5 mm in width, often with curved tips. The white flowers are around 15 mm long and are produced in spikes of 7 to 13. These occur throughout the year. ''Leucopogon parviflorus'' can grow in many differing conditions, from sandy dunes to rocky cliff faces, in sheltered or exposed weather conditions. However, it does grow most efficiently in sandier areas, with sufficient shelter from the elements. It is a significant food source to many Australian coastal birds and insects and relies on these animals for pollination and seed dispersion. It is also commercially cultivated by landscapers and florists to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seal Bay Aquatic Reserve
__NOTOC__ Seal Bay Aquatic Reserve was a marine protected area in the Australian state of South Australia located in waters off the south coast of Kangaroo Island immediately adjoining and including the intertidal zone within the locality of Seal Bay which is also part of the Seal Bay Conservation Park. It was declared on 30 November 1971 as the Seal Beach Aquatic Reserve for the purpose of ‘the protection of a major breeding colony of the Australian sea lion’. The following activities are prohibited in the aquatic reserve - access to waters adjoining Seal Bay by members of the public, fishing, and the collection or the removal of any marine organism. The aquatic reserve covered the full extent of the coastal frontage of Seal Bay and extended seaward a distance of about covering an area of . Its extent included the waters around Nobby Islet. It was bounded by the Bales Beach Aquatic Reserve to its immediate east. On 20 October 2016, it was abolished. Since 2012, it w ...

Protected Area
Protected areas or conservation areas are locations which receive protection because of their recognized natural, ecological or cultural values. There are several kinds of protected areas, which vary by level of protection depending on the enabling laws of each country or the regulations of the international organizations involved. Generally speaking though, protected areas are understood to be those in which human presence or at least the exploitation of natural resources (e.g. firewood, non-timber forest products, water, ...) is limited. The term "protected area" also includes marine protected areas, the boundaries of which will include some area of ocean, and transboundary protected areas that overlap multiple countries which remove the borders inside the area for conservation and economic purposes. There are over 161,000 protected areas in the world (as of October 2010) with more added daily, representing between 10 and 15 percent of the world's land surface area. As of 20 ...

Egernia
''Egernia'' is a genus of skinks (family Scincidae) that occurs in Australia. These skinks are ecologically diverse omnivores that inhabit a wide range of habitats. However, in the loose delimitation (which incorporates about 30 species) the genus is not monophyletic but an evolutionary grade, as has long been suspected due to its lack of characteristic apomorphies. Some of the skinks traditionally placed in ''Egernia'' appear to be among the most intelligent squamates. They have been shown to be able to distinguish between relatives and unrelated conspecifics, and can recognize relatives individually. Several species form monogamous pair-bonds. For instance, the Black Rock Skink is a species who can perform kin discrimination based on scent and form monogamous pair-bonds and a nuclear family structure. Most of these species belong to ''Egernia sensu stricto'', and similar behaviour is also known in the related Solomon Islands skink (''Corucia zebrata''). The latter means that ...

Christinus Marmoratus
''Christinus marmoratus'', also known as marbled gecko or southern marbled gecko, is a species of Gekkonidae (gecko) native to southern mainland of Australia, from Victoria to Western Australia. The species is well adapted to a variety of habitats, including city dwellings.''. Taxonomy The species was first formally described by John Edward Gray in 1845. The name he gave placed this group in the genus '' Diplodactylus'' as ''Diplodactylus marmoratus''. Gray's description was based on four specimens that were preserved in spirits. They were collected on the Abrolhos Islands (off Western Australia), and were donated to the British Museum from the collection of a "Mr. Gilbert". Gray examined another preserved specimen of ''D. marmoratus'' (from a different donor) which was discoloured, leading him to mistakenly describe it as a separate species (''Goniodactylus australis'') in the same publication. In 1885, George Boulenger placed ''D. marmoratus'' in the genus '' Phyllodact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lizard
Lizards are a widespread group of squamate reptiles, with over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic since it excludes the snakes and Amphisbaenia although some lizards are more closely related to these two excluded groups than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards"), have secondarily lost their legs, and have long snake-like bodies. Some such as the forest-dwelling ''Draco'' lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals a ...

White-faced Storm Petrel
The white-faced storm petrel (''Pelagodroma marina''), also known as white-faced petrel is a small seabird of the austral storm petrel family Oceanitidae. It is the only member of the monotypic genus ''Pelagodroma''. Description The white-faced storm petrel is in length with a wingspan. It has a pale brown to grey back, rump and wings with black flight feathers. It is white below, unlike other north Atlantic petrels, and has a white face with a black eye mask like a phalarope. Its plumage makes it one of the easier petrels to identify at sea. Behaviour The white-faced storm petrel is strictly pelagic outside the breeding season, and this, together with its often-remote breeding sites, makes this petrel a difficult bird to see from land. Only in severe storms might this species be pushed into headlands. There have been a handful of western Europe records from France, the United Kingdom and the Netherlands. It has a direct gliding flight and will patter on the water surface as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osprey
The osprey (''Pandion haliaetus''), , also called sea hawk, river hawk, and fish hawk, is a diurnal, fish-eating bird of prey with a cosmopolitan range. It is a large raptor reaching more than in length and across the wings. It is brown on the upperparts and predominantly greyish on the head and underparts. The osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply. It is found on all continents except Antarctica, although in South America it occurs only as a non-breeding migrant. As its other common names suggest, the osprey's diet consists almost exclusively of fish. It possesses specialised physical characteristics and exhibits unique behaviour to assist in hunting and catching prey. As a result of these unique characteristics, it has been given its own taxonomic genus, ''Pandion'', and family, Pandionidae. Taxonomy The osprey was described by Carl Linnaeus under the name ''Falco haliaeetus'' in his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Wallaby Grass
''Rytidosperma caespitosum'', known by various common names including common wallaby-grass, ringed wallaby-grass, and white-top, is a species of grass native to southern parts of Australia. Description It is a tufted perennial grass that reaches up to 90 centimetres high. Flowers are purple or green, and occur in a panicle of from 10 to 30 spikelets, each of which contains from four to nine individual flowers. Taxonomy It was first collected from Shark Bay in Western Australia by Charles Gaudichaud-Beaupré, botanist to the expedition of Louis de Freycinet. It was published by Gaudichaud-Beaupré in 1829 under the name ''Danthonia caespitosa''. During the 1960s and 1970s it was transferred firstly into '' Notodanthonia'' and then into ''Rytidosperma''. In 1993 it was transferred into '' Austrodanthonia'' by Hans Peter Linder. However, in 2010 Austrodanthonia was again submerged into a broader Rytidosperma, and all Austrodanthonia species are now considered part of the genus Ryt ...

Zygophyllum
''Zygophyllum'' is the type genus of the flowering plant family Zygophyllaceae. The generic name is derived from the Greek words ζυγόν (''zygon''), meaning "double", and φυλλον (''phyllon''), meaning "leaf". It refers to the leaves, each of which have two leaflets. The genus is distributed in arid and semi-arid regions of Africa, the Mediterranean Basin, central Asia and Australia. Molecular phylogenetic analysis suggested that as previously circumscribed, ''Zygophyllum'' was not monophyletic, and the genus was split among a number of other genera, including '' Augea'', ''Fagonia'', ''Roepera'' and '' Tetraena''. Species In accordance with International Plant Names Index, genus ''Zygophyllum'' currently has 117 accepted species: *''Zygophyllum acerosum'' (Boiss.)
