Cryptopygus Cisantarcticus
''Cryptopygus cisantarcticus'' is a species of springtail belonging to the family Isotomidae. The species was first described by Keith Arthur John Wise in 1967. The species is native to the Cape Hallett area of Northern Victoria Land in East Antarctica and the surrounding offshore islands, including the Balleny Islands. Taxonomy ''Cryptopygus cisantarcticus'' was identified in 1967, when Wise recognised consistent differences between '' Cryptopygus antarcticus'' found in the Cape Hallett area of Antarctica and the near-by Balleny Islands. The first known specimen was collected in 1962 by Madison E. Pryor, who identified it as ''Cryptopygus antarcticus''. Genetic evidence suggests that ''Cryptopygus cisantarcticus'' diverged from other Antarctic species around 18-11 million years ago, possibly due to increased glaciation creating barriers between populations. Description The species is deep blue to black in colour, with a body length of up to . It can be distinguished from ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collembola
Springtails (Collembola) form the largest of the three lineages of modern hexapods that are no longer considered insects (the other two are the Protura and Diplura). Although the three orders are sometimes grouped together in a class called Entognatha because they have internal mouthparts, they do not appear to be any more closely related to one another than they are to all insects, which have external mouthparts. Collembolans are omnivorous, free-living organisms that prefer moist conditions. They do not directly engage in the decomposition of organic matter, but contribute to it indirectly through the fragmentation of organic matter and the control of soil microbial communities. The word ''Collembola'' is from the ancient Greek "glue" and "peg"; this name was given due to the existence of the collophore, which was previously thought to stick to surfaces to stabilize the creature. Some DNA sequence studies suggest that Collembola represent a separate evolutionary line fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Keith Arthur John Wise
Keith Arthur John Wise (1 June 1926 – 31 March 2012), often referred to as K. A. J. Wise, was a New Zealand entomologist. Originally employed at the Department of Scientific and Industrial Research (New Zealand), Department of Scientific and Industrial Research, Wise began working with the Bishop Museum in the early 1960s, coordinating field programmes for United States visits to Antarctica and Subantarctic islands. This work led Wise to identify and describe large numbers of novel species, including many species of springtail. In 1965, Wise became the first Curator of Entomology at the Auckland War Memorial Museum, where he was integral in creating the first entomology section within the natural history gallery. Early life Wise was born on 1 June 1926 in Wellington. As his father Victor John Wise worked in insurance, Wise moved around the country often, living in Whangarei, Invercargill and Oamaru, attending Whangarei Boys' High School, Southland Boys' High School and Waitak ...

Cape Hallett
Cape Hallett is a snow-free area (Antarctic oasis) on the northern tip of the Hallett Peninsula on the Ross Sea coast of Victoria Land, East Antarctica. Cape Adare lies to the north. History In 1956, during Operation Deep Freeze II, was damaged by an ice floe at Cape Hallett. Hallett Station The cape was the location of a joint scientific base, Hallett Station, between the United States and New Zealand during the International Geophysical Year of 1957, and was manned permanently until 1964, when there was a major fire. It was then used as a summer only base until 1973. The site is currently being remediated by removing hazardous materials: fuel, and oil stored in several large tanks. This is an ongoing project which will take several years to complete. Antarctic Specially Protected Area An area of 74 ha is protected under the Antarctic Treaty System as Antarctic Specially Protected Area (ASPA) No.106 because it contains habitats with a rich and diverse range of ...

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Antarctica
East Antarctica, also called Greater Antarctica, constitutes the majority (two-thirds) of the Antarctic continent, lying on the Indian Ocean side of the continent, separated from West Antarctica by the Transantarctic Mountains. It lies almost entirely within the Eastern Hemisphere and its name has been accepted for more than a century. It is generally higher than West Antarctica and includes the Gamburtsev Mountain Range in the center. The geographic South Pole is located within East Antarctica. Apart from small areas of the coast, East Antarctica is permanently covered by ice and it has relatively low biodiversity, with only a small number of species of terrestrial plants, animals, algae, and lichens. The coasts are the breeding ground for various seabirds and penguins, and the leopard seal, Weddell seal, elephant seal, crabeater seal and Ross seal breed on the surrounding pack ice in summer.

Balleny Islands
The Balleny Islands () are a series of uninhabited islands in the Southern Ocean extending from 66°15' to 67°35'S and 162°30' to 165°00'E. The group extends for about in a northwest-southeast direction. The islands are heavily glaciated and of volcanic origin. Glaciers project from their slopes into the sea. The islands were formed by the so-called Balleny hotspot. The group includes three main islands: Young, Buckle and Sturge, which lie in a line from northwest to southeast, and several smaller islets and rocks: *northeast of Young Island: Seal Rocks, Pillar *southeast of Young Island: Row Island, Borradaile Island (with Swan Base shelter hut) *south of Buckle Island: Scott Cone, Chinstrap Islet, Sabrina Islet (with Sabrina Refuge shelter hut), and the Monolith The islands are claimed by New Zealand as part of the Ross Dependency (see Territorial claims in Antarctica). Islands and rocks from north to south The islands' area totals and the highest point has been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptopygus Antarcticus
The Antarctic springtail, ''Cryptopygus antarcticus'', is a species of springtail native to Antarctica and Australia. ''Cryptopygus antarcticus'' average long and weigh only a few micrograms. Like other springtails, the Antarctic springtail too has been found to be useful as a bioindicator of pollution and has been used to study microplastic pollution in Antarctica. They also tend aggregate, by signaling to other individuals via pheromones, specially when temperatures Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness. Temperature is measured with a thermometer. Thermometers are calibrated in various temperature scales that historically have relied o ... are low, to avoid a high water loss rate.

Moss
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) '' sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are a ...

Animals Described In 1967
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms and ...

Entomobryomorpha
The Entomobryomorpha are one of the three main groups ( order) of springtails (Collembola), tiny hexapods related to insects. This group was formerly treated as a superfamily, the Entomobryoidea. They can be best distinguished from the other springtail groups by their body shape. The Symphypleona are very round animals, almost spherical. The Poduromorpha are also very plump but have a more oval shape. The Entomobryomorpha, by contrast, contain the slimmest springtails. They either have short legs and antennae, but their long bodies set them apart, or long legs and antennae, as well as well-developed furculae; these are the most characteristic members of the order. Systematics The Entomobryomorpha were, as Entomobryoidea, united with the Poduromorpha (then called Poduroidea) in a group called "Arthropleona", but this has more recently turned out to be paraphyletic. Actually, the Entomobryomorpha, the Poduromorpha, and the third springtaill lineage – the Symphypleona – a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of Antarctica
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
