Vernon Victor Hickman
Vernon Victor Hickman (1894–1984) was an entomologist, born and resident in Tasmania, who became a leading authority on the spiders of Australia. The genus '' Hickmania'' and its formerly recognised family Hickmaniidae were named in tribute to the author. In 1979 Hickman was awarded the title Officer of the Order of the British Empire (OBE) "for service to zoological science and education". Hickman was proudest of the Anders Retzius medal, awarded in 1951, but said to be modest regarding his other achievements. Hickman was the eldest son of Pauline née Patterson and her husband, George Milford Hickman, a Tasmanian storekeeper. He was educated at the University of Tasmania and briefly lectured before enlisting to serve in first world war, returning from the experience of the Western Front with a psychological impact that remained throughout his life.Eric Guiler, 'Hickman, Vernon Victor (1894–1984)', Australian Dictionary of Biography, National Centre of Biography, Australian ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Arthropods Of Tasmania
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Spiders Of Australia
Australia has a number of highly venomous spiders, including the Sydney funnel-web spider, its relatives in the family Hexathelidae, and the redback spider, whose bites can be extremely painful and have historically been linked with deaths in medical records. Most Australian spiders do not have venom that is considered to be dangerously toxic. No deaths caused by spider bites in Australia have been substantiated by a coronial inquest since 1979. There are sensationalised news reports regarding Australian spiders that fail to cite evidence. ''A Field Guide to Spiders of Australia'' published by CSIRO Publishing in 2017 featuring around 836 species illustrated with photographs of live animals, around 381 genera and 78 families, introduced significant updates to taxonomy from Ramirez, Wheeler and Dmitrov Estimates put the total number of Australian spider species at about 10,000. Only around 3,600 have been described. Little information is known about many undiscovered species. New s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stanwellia
''Stanwellia'' is a genus of South Pacific mygalomorph spiders in the family Pycnothelidae. It was first described by W. J. Rainbow & R. H. Pulleine in 1918. Originally placed with the curtain-web spiders, it was transferred to the funnel-web trapdoor spiders in 1985, then to the Pycnothelidae in 2020. It is a senior synonym of ''Aparua''. Species it contains eighteen species, found in New Zealand and Australia: *'' Stanwellia annulipes'' ( C. L. Koch, 1841) – Australia (Tasmania) *'' Stanwellia bipectinata'' (Todd, 1945) – New Zealand *'' Stanwellia grisea'' ( Hogg, 1901) – Australia (Victoria) *'' Stanwellia hapua'' ( Forster, 1968) – New Zealand *'' Stanwellia hoggi'' (Rainbow, 1914) ( type) – Australia (New South Wales) *'' Stanwellia hollowayi'' (Forster, 1968) – New Zealand *'' Stanwellia houhora'' (Forster, 1968) – New Zealand *'' Stanwellia inornata'' Main, 1972 – Australia (Victoria) *'' Stanwellia kaituna'' (Forster, 1968) – New Zealand *'' Stanwell ...

Predation
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and inv ...

Terrestrial Animal
Terrestrial animals are animals that live predominantly or entirely on land (e.g. cats, dogs, ants, spiders), as compared with aquatic animals, which live predominantly or entirely in the water (e.g. fish, lobsters, octopuses), and amphibians, which rely on a combination of aquatic and terrestrial habitats (e.g. frogs and newts). Some groups of insects are terrestrial, such as ants, butterflies, earwigs, cockroaches, grasshoppers and many others, while other groups are partially aquatic, such as mosquitoes and dragonflies, which pass their larval stages in water. Terrestrial animals tend to be more developed and intelligent than aquatic animals. Terrestrial classes The term "terrestrial" is typically applied to species that live primarily on the ground, in contrast to arboreal species, which live primarily in trees. There are other less common terms that apply to specific groups of terrestrial animals: *Saxicolous creatures are rock dwelling. "Saxicolous" is derived from t ...

Fossorial
A fossorial () animal is one adapted to digging which lives primarily, but not solely, underground. Some examples are badgers, naked mole-rats, clams, meerkats, and mole salamanders, as well as many beetles, wasps, and bees. Prehistoric evidence The physical adaptation of fossoriality is widely accepted as being widespread among many prehistoric phyla and taxa, such as bacteria and early eukaryotes. Furthermore, fossoriality has evolved independently multiple times, even within a single family. Fossorial animals appeared simultaneously with the colonization of land by arthropods in the late Ordovician period (over 440 million years ago). Other notable early burrowers include ''Eocaecilia'' and possibly ''Dinilysia''. The oldest example of burrowing in synapsids, the lineage which includes modern mammals and their ancestors, is a cynodont, ''Thrinaxodon liorhinus'', found in the Karoo of South Africa, estimated to be 251 million years old. Evidence shows that this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hobart
Hobart ( ; Nuennonne/Palawa kani: ''nipaluna'') is the capital and most populous city of the Australian island state of Tasmania. Home to almost half of all Tasmanians, it is the least-populated Australian state capital city, and second-smallest if territories are taken into account, before Darwin, Northern Territory. Hobart is located in Tasmania's south-east on the estuary of the River Derwent, making it the most southern of Australia's capital cities. Its skyline is dominated by the kunanyi/Mount Wellington, and its harbour forms the second-deepest natural port in the world, with much of the city's waterfront consisting of reclaimed land. The metropolitan area is often referred to as Greater Hobart, to differentiate it from the City of Hobart, one of the five local government areas that cover the city. It has a mild maritime climate. The city lies on country which was known by the local Mouheneener people as nipaluna, a name which includes surrounding features such as ...
