Henry Roughton Hogg
Henry Roughton Hogg (9 February 1846 – 30 November 1923) was a British amateur arachnologist and businessman who lived in both Australia and Britain. Hogg emigrated to Australia in December 1873 and co-founded a mercantile and shipping agency in Melbourne, becoming a prominent member of the business community. He joined the Field Naturalists' Club and the Royal Society of Victoria and acquired a specialist knowledge of the Spider, spiders of Australia and New Zealand. Hogg was given access to specimens of spiders collected by the 1894 Horn expedition, Horn scientific expedition to central Australia and contributed the section on spiders in the published results of the expedition. Hogg and his wife returned to England in August 1900. He continued to study spiders and contributed regular articles to the ''Proceedings of the Zoological Society of London'' and other publications and scientific journals, often providing the first descriptions of new species. His earlier papers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 associated. 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 ...

Arthropods Of Victoria (state)
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an exoskeleton with a cuticle made of chitin, often mineralised with calcium carbonate, a body with differentiated ( metameric) segments, and paired jointed appendages. 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. They form an extremely diverse group of up to ten million species. Haemolymph is the analogue of blood for most arthropods. An arthropod has an open circulatory system, with a body cavity called a haemocoel through which haemolymph circulates to the interior Organ (anatomy), organs. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. They have ladder-like nervous systems, with paired Anatomical terms of location#Dorsal and ventral, ventral Ventral nerve cord, nerve cords running through all segments and forming paired ganglia in each segment. Their heads are f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Australia
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

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 ...

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 the genus contained eighteen species, found in New Zealand (NZ) and the Australian states of New South Wales (NSW), Victoria (VIC), South Australia (SA) and Tasmania (TAS): *'' Stanwellia annulipes'' ( C. L. Koch, 1841) – TAS *'' Stanwellia bipectinata'' (Todd, 1945) – NZ *''Stanwellia grisea'' ( Hogg, 1901) – VIC *''Stanwellia hapua'' ( Forster, 1968) – NZ *''Stanwellia hoggi'' (Rainbow, 1914) (type) – NSW *''Stanwellia hollowayi'' (Forster, 1968) – NZ *''Stanwellia houhora'' (Forster, 1968) – NZ *''Stanwellia inornata'' Main, 1972 – VIC *''Stanwellia kaituna'' (Forster, 1968) – NZ *''Stanwellia media'' (Forster, ...

Spider Silk
Spider silk is a protein fibre or silk spun by spiders. Spiders use silk to make webs or other structures that function as adhesive traps to catch prey, to entangle and restrain prey before biting, to transmit tactile information, or as nests or cocoons to protect their offspring. They can use the silk to suspend themselves from height, to float through the air, or to glide away from predators. Most spiders vary the thickness and adhesiveness of their silk according to its use. In some cases, spiders may use silk as a food source. While methods have been developed to collect silk from a spider by force, gathering silk from many spiders is more difficult than from silk-spinning organisms such as silkworms. All spiders produce silk, although some spiders do not make webs. Silk is tied to courtship and mating. Silk produced by females provides a transmission channel for male vibratory courtship signals, while webs and draglines provide a substrate for female sex pheromone ...

Predation
Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. It is one of a family of common List of feeding behaviours, feeding behaviours that includes parasitism and micropredation (which usually do not kill the Host (biology), host) and parasitoidism (which always does, eventually). It is distinct from Scavenger, scavenging on dead prey, though many predators also scavenge; it overlaps with Herbivore, herbivory, as Seed predation, seed predators and destructive frugivores are predators. Predation behavior varies significantly depending on the organism. Many predators, especially carnivores, have evolved distinct hunting strategy, hunting strategies. Pursuit predation involves the active search for and pursuit of prey, whilst ambush predation, ambush predators instead wait for prey to present an opportunity for capture, and often use stealth or aggressive mimicry. Other predators are opportunism, opportunistic or om ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terrestrial Animal
Terrestrial animals are animals that live predominantly or entirely on land (e.g. cats, chickens, ants, most spiders), as compared with aquatic animals, which live predominantly or entirely in the water (e.g. fish, lobsters, octopuses), and semiaquatic animals, which rely on both aquatic and terrestrial habitats (e.g. platypus, most amphibians). 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. Alternatively, terrestrial is used to describe animals that live on the ground, as opposed to arboreal animals that live in trees. Ecological subgroups The term "terrestrial" is typically applied to species that live primarily on or in the ground, in contrast to arboreal species, who live primarily in trees, even though the latter are actually a specialized subgroup of the terre ...

Fossorial
A fossorial animal () is one that is adapted to digging and which lives primarily (but not solely) underground. Examples of fossorial vertebrates are Mole (animal), moles, badgers, naked mole-rats, meerkats, armadillos, wombats, and mole salamanders. Among invertebrates, many molluscs (e.g., clams), insects (e.g., beetles, wasps, bees), and arachnids (e.g. spiders) are fossorial. Prehistoric evidence The physical adaptation of fossoriality is widely accepted as being widespread among many Prehistory, prehistoric Phylum, phyla and Taxon, taxa, such as bacteria and early eukaryotes. Furthermore, fossoriality has evolved independently multiple times, even within a single Family (biology), 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 lineag ...

Macedon, Victoria
Macedon ( ) is a town at the foot of Mount Macedon in the Macedon Ranges, between Melbourne and Bendigo in central Victoria. It is administered by the Shire of Macedon Ranges. Macedon's urban population was 2,926 at the 2021 census, up from 2,808 in the . The combined population of Macedon and the nearby larger town of Gisborne was 21,071 Estimated resident population, 30 June 2016. at June 2016. Etymology Macedon's name derives from the Ancient Kingdom of Macedon. The toponym Macedon is derived itself from the ancient Greek adjective μακεδνός (''makednós''), meaning "tall", possibly descriptive of the inhabitants of Macedon.Liddell and Scott 1940. It has the same root as the adjective μακρός (''makros''), meaning "long" or "tall" in Ancient Greek. The name is originally believed to have meant either "highlanders", "the tall ones", or "high grown men".; ; Eugene N. Borza writes that the "highlanders" or "Makedones" of the mountainous regions of western Mace ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grampians National Park
The Grampians National Park, commonly known as the Grampians, is a national park located in the Grampians region of Victoria, Australia. The Jardwadjali name for the mountain range itself is Gariwerd. The national park is situated between and on the Western Highway and on the Glenelg Highway, west of Melbourne and east of Adelaide. Proclaimed as a national park on 1 July 1984, the park was listed on the National Heritage List on 15 December 2006 for its outstanding natural beauty and being one of the richest Aboriginal rock art sites in south-eastern Australia. The Grampians feature a striking series of mountain ranges of sandstone. The Gariwerd area features about 90% of the rock art in the state. Etymology At the time of European colonisation, the Grampians had a number of indigenous names, one of which was ''Gariwerd'' in the western Kulin language of the Mukjarawaint, Jardwadjali, and Djab Wurrung people, who lived in the area and who shared 90 per cent of ...
