Synsphyronus Spatiosus
''Synsphyronus spatiosus'' is a species of pseudoscorpion in the Garypidae family. It is endemic to Australia. It was described in 2022 by Australian arachnologist Mark Harvey. The specific epithet ''spatiosus'' (Latin: 'spacious' or 'large') refers to both the large size of the species and of the type locality. Description Body lengths of males are 3.34–4.04 mm; those of females 4.10–4.50 mm. Colouration is generally yellowish-brown. Distribution and habitat The species occurs in Western Australia on granite outcrops in the Murchison bioregion. The type locality is Walga Rock, on Austin Downs station, where the pseudoscorpions were found beneath exfoliating granite slabs. Behaviour The pseudoscorpions are terrestrial predators 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 feeding behaviours that includes parasitism and micropredation (which usu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mark Harvey (arachnologist)
Mark Stephen Harvey (born 17 September 1958) is a museum scientist and biologist. Since 1989 he has been based at the Western Australian Museum as Curator of Arachnids and Myriapods. Career Harvey graduated from Monash University in 1983 with a PhD titled "Contributions to the systematics of the Pseudoscorpionida (Arachnida) : the genus ''Synsphyronus'' Chamberlin (Garypidae) and the family Sternophoridae". His research interests include the systematics and evolution of arachnids and other terrestrial invertebrates. He has published 374 scientific papers or books, and was instrumental in the promotion of short-range endemism Short-range endemic invertebrates through a paper outlining the criteria for recognising taxa that could be considered short-range endemics. His primary research interests are with Pseudoscorpions. As of 2024, he has described 888 new species, 93 new genera and four new families including the aquatic mite family Pezidae and the pseudoscorpion family Lar ...

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 Western Australia
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an arthropod exoskeleton, exoskeleton with a cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate, a body with differentiated (Metamerism (biology), metameric) Segmentation (biology), 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 cord ...

Pseudoscorpions Of Australia
Pseudoscorpions, also known as false scorpions or book scorpions, are small, scorpion-like arachnids belonging to the order Pseudoscorpiones, also known as Pseudoscorpionida or Chelonethida. Pseudoscorpions are generally beneficial to humans because they prey on clothes moth larvae, carpet beetle larvae, booklice, ants, mites, and small flies. They are common in many environments, but they are rarely noticed due to their small size. When people see pseudoscorpions, especially indoors, they often mistake them for ticks or small spiders. Pseudoscorpions often carry out phoresis, a form of commensalism in which one organism uses another for the purpose of transport. Characteristics Pseudoscorpions belong to the class Arachnida. They are small arachnids with a flat, pear-shaped body, and pincer-like pedipalps that resemble those of scorpions. They usually range from in length.Pennsylvania State University, DepartmentEntomological Notes: Pseudoscorpion Fact Sheet/ref> The large ...

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 ...

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 ...

Exfoliating Granite
Exfoliating granite is a granite undergoing exfoliation, or onion skin weathering (desquamation). The external delaminated layers of granite are gradually produced by the cyclic variations of temperature at the surface of the rock in a process also called spalling. Frost and ice expansion in the joints during the winter accelerate the alteration process while the most unstable loose external layers are removed by gravity assisted by surface runoff of water. Geology Homogeneous granitic plutons are created in high-pressure environments and slowly solidify beneath the Earth's crust. Vertical compression of overburden releases through erosion, or removal of overlying rocks resulting in unloading. Other contributors of unloading are tectonic uplift, glacier retreat, and mass wasting. The pressure is relieved when the granite is exposed at the surface, allowing it to expand towards the atmosphere. On the surface, if the granite is not jointed, or if it has few joints, then th ...

Station (Australian Agriculture)
In Australia and New Zealand, a station is a large landholding used for producing livestock, predominantly cattle or sheep, that needs an extensive range of grazing land. The owner of a station is called a pastoralism, pastoralist or a wikt:grazier, grazier, corresponding to the North American term "rancher". Originally ''station'' referred to the homestead (buildings), homestead – the owner's house and associated outbuildings of a pastoral property, but it now generally refers to the whole holding. Stations in Australia are on Crown land pastoral leases, and may also be known more specifically as sheep stations or cattle stations, as most are stock-specific, dependent upon the region and rainfall. If they are very large, they may also have a subsidiary homestead, known as an outstation. Sizes Sheep and cattle stations can be thousands of square kilometres in area, with the nearest neighbour being hundreds of kilometres away. Anna Creek Station in South Australia is th ...

Austin Downs
Austin Downs Station or Austin Downs is a pastoral lease in the Mid West region of Western Australia. Description The property covers an area of and has traditionally farmed sheep for the production of wool. The station is located in the Murchison region of Western Australia; the nearest town is Cue, to the south east of the homestead. An area of within the station is composed of reserves and crown land. The soil has a low level of erosion, with 96% of the land being described as nil or minor. The perennial vegetation condition is good with 15% of vegetation cover being described as poor or very poor. The station contains part of Lake Austin and close to Nallan Creek. The station land includes Walga Rock, a large granite monolith. History 128 bales of greasy wool from the station were sold in London in 1910 at 11d. per pound. Later the same year a bank clerk named Studds from Cue committed suicide on the property and was found several weeks later with his revolver still ...

Walga Rock
Walga Rock, also known as Walgahna Rock and Walganna Rock, is a granite monolith situated about west of Cue, Western Australia, within the Austin Downs pastoral lease. It is one of the largest granite monoliths in Australia. It is of profound cultural significance to Aboriginal people; the Wajarri elders are the acknowledged traditional owners. An extensive gallery of Aboriginal art exists within a cave in Walga Rock. While it is the subject of a great deal of research and fieldwork subsequent to a detailed examination conducted in the 1930s by the American anthropologist Davidson (who considered it to be "one of the most extensive galleries so far reported in Australia"), the first known European record of Walga is by Daisy Bates. Though she did not visit the rock and its gallery when travelling through the region in 1908, "Walga" is marked near the mining towns of Cue and Day Dawn and many other sites of Aboriginal significance on sketch Map 19 held at the State Library of W ...
