Pullen Island (South Australia)
Pullen Island is a 1 ha granite island lying 0.5 km offshore from the town of Port Elliot on the southern coast of the Fleurieu Peninsula of South Australia. It was originally named Lipson Island but was renamed in 1839 by W.J.S. Pullen, the Colonial Marine Surveyor, after himself. The island is protected by designation as the Pullen Island Conservation Park. Description About 300 m long, the island that is largely a mass of weathered granite boulders, with a cove and beach on the northern side providing a landing for small boats. There is little vegetation, though pockets of soil on the higher part of the island support a few plants including the native common boobialla and introduced African boxthorn, tree mallow and buckthorn. Seabirds breeding on the island include little penguins and silver gulls. There is also a large roost of feral pigeons.

Encounter Bay
Encounter Bay is a bay in the Australian state of South Australia located on the state's south central coast about south of the state capital of Adelaide. It was named by Matthew Flinders after his encounter on 8 April 1802 with Nicolas Baudin, the commander of the Baudin expedition of 1800–03. It is the site of both the mouth of the River Murray and the regional city of Victor Harbor. It is one of four "historic bays" located on the South Australian coast. Extent There are at least two definitions of the bay’s extent: *Firstly, the US National Geospatial-Intelligence Agency states that Newland Head is its westerly extremity while the mouth of the River Murray is the easterly extremity. *Secondly, Australian authorities consider the bay’s extent consists of all of the sea north of a line running east from the southern tip of Rosetta Head to the Younghusband Peninsula. Encounter Bay is one of four bays on the South Australian coast considered by the Australian go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lavatera Arborea
''Malva arborea'' (also known as ''Lavatera arborea'', or, more recently as ''Malva eriocalyx''), the tree mallow, is a species of mallow native to the coasts of western Europe and the Mediterranean region, from Ireland and Britain south to Algeria and Libya, and east to Greece.Malvaceae Pages''Lavatera arborea''/ref>Flora Europaea''Lavatera arborea''/ref>''Botanica.

National Parks And Wildlife Act 1972
Protected areas of South Australia consists of protected areas located within South Australia and its immediate onshore waters and which are managed by South Australian Government agencies. As of March 2018, South Australia contains 359 separate protected areas declared under the ''National Parks and Wildlife Act 1972'', the ''Crown Land Management Act 2009'' and the ''Wilderness Protection Act 1992'' which have a total land area of or 21.5% of the state's area. Jurisdiction The jurisdiction for legislation of protected areas within South Australia and the immediate onshore waters known officially as ‘the coastal waters and waters within the limits of South Australia' belongs to the South Australian government. The major piece of legislation concerned with the creation and the subsequent management of protected areas is the ''National Parks and Wildlife Act 1972''. Protected areas created by this Act form the majority of South Australia’s contribution to the National Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flinders University
Flinders University is a public research university based in Adelaide, South Australia, with a footprint extending across 11 locations in South Australia and the Northern Territory.

Feral Pigeon
Feral pigeons (''Columba livia domestica'' or ''Columba livia forma urbana''), also called city doves, city pigeons, or street pigeons,Nagy, Kelsi, and Johnson, Phillip David. ''Trash animals: how we live with natures filthy, feral, invasive, and unwanted species''. Minneapolis (Minn.), University of Minnesota Press, 2013.Blechman, Andrew D. ''Pigeons: The Fascinating Saga of the World’s Most Revered and Reviled Bird'', St Lucia, Qld., University of Queensland Press, 2007. are descendants of domestic pigeons (''Columba livia domestica'') that have returned to the wild. The domestic pigeon was originally bred from the wild rock dove, which naturally inhabits sea-cliffs and mountains. Rock, domestic, and feral pigeons are all the same species and will readily interbreed. Feral pigeons find the ledges of buildings to be a substitute for sea cliffs, have become adapted to urban life, and are abundant in towns and cities throughout much of the world. Owing to their abilities to crea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Gull
The silver gull (''Chroicocephalus novaehollandiae'') is the most common gull of Australia. It has been found throughout the continent, but particularly at or near coastal areas. It is smaller than the Pacific gull (''Larus pacificus''), which also lives in Australia. The silver gull should not be confused with the herring gull, which is called "silver gull" in many other languages (scientific name ''Larus argentatus'', German ''Silbermöwe'', French ''Goéland argenté'', Dutch ''zilvermeeuw''), but is a much larger, robust gull with no overlap in range. Taxonomy It has traditionally been placed in the genus ''Larus'', as is the case with many gulls, but is now placed in the genus ''Chroicocephalus''. Hartlaub's gull (''C. hartlaubii'') of South Africa was formerly sometimes considered to be subspecies of the silver gull. There are three subspecies: * ''C. n. forsteri'' ( Mathews, 1912) – north and northeast Australia, New Caledonia, Loyalty Islands * ''C. n. novaehollan ...

Little Penguin
The little penguin (''Eudyptula minor'') is a species of penguin from New Zealand. They are commonly known as little blue penguins or blue penguins owing to their slate-blue plumage and are also known by their Māori name . The Australian little penguin (''Eudyptula novaehollandiae'') from Australia and the Otago region of New Zealand is considered a separate species by a 2016 study and a 2019 study. Taxonomy The little penguin was first described by German naturalist Johann Reinhold Forster in 1781. Several subspecies are known, but a precise classification of these is still a matter of dispute. The holotypes of the subspecies ''E. m. variabilis'' and ''Eudyptula minor chathamensis'' are in the collection of the Museum of New Zealand Te Papa Tongarewa. The white-flippered penguin (''E. m. albosignata'' or ''E. m. minor morpha albosignata'') is currently considered by most taxonomists to be a colour morph or subspecies of ''Eudyptula minor.'' In 2008, Shirihai treated th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seabird
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely. Seabirds and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhamnus Alaternus
''Rhamnus alaternus'' is a species of flowering plant in the buckthorn family Rhamnaceae, known by the common names Italian buckthorn or Mediterranean buckthorn. It is a hardy medium-sized evergreen shrub with fragrant flowers. Etymology The specific Latin name ''alaternus'', is from the Latin word for the plant. Its origin is obscure but is often suggested to be of Etruscan or pre-Indo-European Mediterranean origin. Description ''Rhamnus alaternus'' is an evergreen shrub high.Pignatti S. - Flora d'Italia – Edagricole – 1982. Vol. II, pag. 78 The stems have reddish bark and pubescent young branches, rounded and compact foliage with alternating leaves, long, sometimes nearly opposite, oval or lanceolate, leathery, shiny green, yellowish-green underneath.

Lycium Ferocissimum
''Lycium ferocissimum'', the African boxthorn or boxthorn, is a shrub in the nightshade family (Solanaceae). The species is native to the Western Cape, Eastern Cape, and Free State provinces in South Africa and has become naturalised in Australia and New Zealand. It is listed in Australia's Weed of National Significance list and is a declared noxious weed in the United States. Description African boxthorn is a large shrub which grows up to high and is covered in spines. The leaves are oval in shape and are long and in width. The solitary flowers emerge from the leaf axils and are purplish. The species was first formally described in 1854 by British botanist John Miers in the ''Annals and Magazine of Natural History''. His description was based on plant material collected from Uitenhage in South Africa South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
