Pseudechis Porphyriacus
The red-bellied black snake (''Pseudechis porphyriacus'') is a species of venomous snake in the Family (biology), family Elapidae, indigenous to Australia. Originally described by George Shaw (biologist), George Shaw in 1794 as a species new to science, it is one of eastern Australia's most commonly encountered snakes. Averaging around in length, it has glossy black upperparts, bright red or orange flanks, and a pink or dull red belly. It is not aggressive and generally retreats from human encounters, but will defend itself if provoked. Although its Snake venom, venom can cause significant illness, no deaths have been recorded from its bite, which is less venomous than other Australian elapid snakes. The venom contains neurotoxins, myotoxins, and Coagulation#Procoagulants, coagulants and has haemolytic properties. Victims can also lose their sense of smell. Common in woodlands, forests, swamplands, along river banks and waterways, the red-bellied black snake often ventures i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coagulation
Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a thrombus, blood clot. It results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair. The process of coagulation involves Platelet-activating factor, activation, Cell adhesion, adhesion and aggregation of platelets, as well as deposition and maturation of fibrin. Coagulation begins almost instantly after an injury to the endothelium that lines a blood vessel. Exposure of blood to the subendothelial space initiates two processes: changes in platelets, and the exposure of subendothelial Tissue factor, platelet tissue factor to coagulation factor VII, which ultimately leads to cross-linked fibrin formation. Platelets immediately form a plug at the site of injury; this is called ''primary hemostasis. Secondary hemostasis'' occurs simultaneously: additional coagulation factors beyond factor VII (#Coagulation factors, listed below) respond in a c ...

Darug
The Dharug or Darug people, are a nation of Aboriginal Australian clans, who share ties of kinship, country and culture. In pre-colonial times, they lived as hunters in the region of current day Sydney. The Darug speak one of two dialects of the Dharug language related to their coastal or inland groups. There was armed conflict between the Dharug and the English settlers in the first half of the 19th century. Controversy over land rights, deference to culture and official return of Dharug artifacts, such as the skull of the warrior Pemulwuy, were a main cause of such conflict. Dharug country Dharug country covers an area of approximately 6,000 km2 (2,300 square miles). In the north, it reaches the Hawkesbury River and its mouth at Broken Bay, creating a border with the Awabakal. To the northwest, the Dharug country extends to the town of Mount Victoria in the Blue Mountains meeting the Darkinjung. To the west, Wiradjuri country begins at the eastern fringe of the B ...

Eora
The Eora (; also ''Yura'') are an Aboriginal Australian people of New South Wales. Eora is the name given by the earliest European settlers to a group of Aboriginal people belonging to the clans along the coastal area of what is now known as the Sydney basin, in New South Wales, Australia. The Eora share a language with the Darug people, whose traditional lands lie further inland, to the west of the Eora. Contact with the first white settlement's bridgehead into Australia quickly devastated much of the population through epidemics of smallpox and other diseases. Their descendants live on, though their languages, social system, way of life and traditions are mostly lost. Radiocarbon dating suggests human activity occurred in and around Sydney for at least 30,000 years, in the Upper Paleolithic period. However, numerous Aboriginal stone tools found in Sydney's far western suburbs gravel sediments were dated to be from 45,000 to 50,000 years BP, which would mean that humans co ...

Eric Worrell
Eric Arthur Frederic Worrell, MBE (27 October 1924 – 13 July 1987) was an Australian herpetologist, naturalist, science writer and zoo founder and director, known for establishing the Australian Reptile Park at Wyoming on the NSW Central Coast in 1959. Worrell's collection of snake venom was utilised by the Australian Serum Laboratories as essential in the production of snake anti-venom in Australia. Early life Worrell was born at Granville, New South Wales the son of salesman and taxidriverNancy Cushing and Kevin Markwell ''Snake-Bitten: Eric Worrell and the Australian Reptile Park'' University of New South Wales Press (2010) (Charles) Percy Frederic Worrell and his wife Rita Mary Ann Worrell (née Rochester).

Johann Georg Wagler
Johann Georg Wagler (28 March 1800 – 23 August 1832) was a German herpetologist and ornithologist. Wagler was assistant to Johann Baptist von Spix, and gave lectures in zoology at the Ludwig Maximilian University of Munich after it was moved to Munich. He worked on the extensive collections brought back from Brazil by Spix, and published partly together with him books on reptiles from Brazil. Wagler wrote ''Monographia Psittacorum'' (1832), which included the correct naming of the blue macaws. In 1832, Wagler died of an accidental self-inflicted gunshot wound while out collecting in München-Moosach. Life Johann Georg Wagler was a German naturalist and scientist in the 19th century, whose works primarily focused on herpetology and ornithology (Beolens, Watkins & Grayson, 2011).

After taking up gymnastics at Nuremberg, Johann Georg W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudechis
''Pseudechis'' is a genus of venomous snakes in the family Elapidae. It contains the group of elapid species commonly referred to as the black snakes. Species of ''Pseudechis'' are found in every Australian state with the exception of Tasmania, and some species are found in Papua New Guinea. They inhabit a variety of habitat types, from arid areas to swampland. All species are dangerous (''Pseudechis'' signifying "like a viper", Greek '' echis'') and can inflict a potentially lethal bite. Most snakes in this genus reach about 2 m (6.6 ft) in total length (including tail), and vary in colour. Some species are brown, whereas others are black. The most recognisable and widespread species in the genus are the red-bellied black snake (''P. porphyriacus'') and the mulga snake (king brown) (''P. australis''). These snakes feed on lizards, frogs, birds, small mammals, and even other snakes. All species of ''Pseudechis'' lay eggs with the exception of the red-bellied black snake ...

Syntype
In biological nomenclature, a syntype is any one of two or more biological types that is listed in a description of a taxon where no holotype was designated. Precise definitions of this and related terms for types have been established as part of the International Code of Zoological Nomenclature and the International Code of Nomenclature for algae, fungi, and plants. In zoology In zoological nomenclature, a syntype is defined as "Each specimen of a type series (q.v.) from which neither a holotype nor a lectotype has been designated rts. 72.1.2, 73.2, 74 The syntypes collectively constitute the name-bearing type." (Glossary of the zoological Code). Historically, it was common to describe a new species or subspecies from several syntypes without designating a holotype, but this practice is generally frowned upon by modern taxonomists, and most are gradually being replaced by lectotypes. Those that still exist are still considered name-bearing types. A lectotype may be designated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elapid
Elapidae (, commonly known as elapids , from , variant of "sea-fish") is a family (biology), family of snakes characterized by their permanently erect fangs at the front of the mouth. Most elapids are venomous, with the exception of the genus ''Emydocephalus''. Many members of this family exhibit a threat display of rearing upwards while spreading out a neck flap. Elapids are endemic to tropics, tropical and subtropics, subtropical regions around the world, with terrestrial forms in Asia, Australia, Africa, and the Americas and marine forms in the Pacific Ocean, Pacific and Indian Oceans. Members of the family have a wide range of sizes, from the white-lipped snake to the king cobra. Most species have neurotoxins, neurotoxic venom that is channeled by their hollow fangs, and some may contain other toxic components in varying proportions. The family includes 55 genera with around 360 species and over 170 subspecies. Description terrestrial animal, Terrestrial elapids look sim ...

Habitat Fragmentation
Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment (suspected of being one of the major causes of speciation), and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species. More specifically, habitat fragmentation is a process by which large and contiguous habitats get divided into smaller, isolated patches of habitats. Definition The term habitat fragmentation includes five discrete phenomena: * Reduction in the total area of the habitat * Decrease of the interior: edge ratio * Isolation of one habitat fragment from other areas of habitat * Breaking up of one patch of habitat into several smaller patches * Decrease in the average size of each patch of habit ...
