Crotoniidae are a family of mites of the Holosomata group that may be the first animal lineage to have abandoned sexual reproduction and then re-evolved it. This is a spectacular case of atavism, and later convergent evolution. [1]

Oceania Football Confederation Confederation of soccer

The Oceania Football Confederation (OFC) is one of the six continental confederations of international association football. The OFC's members consist of New Zealand, Papua New Guinea, and several Pacific Island countries; it promotes the game in Oceania and allows the member nations to qualify for the FIFA World Cup.

<i>Nothofagus</i> Genus of plants

Nothofagus, also known as the southern beeches, is a genus of 43 species of trees and shrubs native to the Southern Hemisphere in southern South America and Australasia. The species are ecological dominants in many temperate forests in these regions. Some species are reportedly naturalised in Germany and Great Britain. The genus has a rich fossil record of leaves, cupules, and pollen, with fossils extending into the late Cretaceous period and occurring in Australia, New Zealand, Antarctica, and South America. In the past, they were included in the family Fagaceae, but genetic tests revealed them to be genetically distinct, and they are now included in their own family, Nothofagaceae.

Antarctic flora Distinct community of plants which evolved on the supercontinent of Gondwana

The Antarctic flora is a distinct community of vascular plants which evolved millions of years ago on the supercontinent of Gondwana. It is now found on several separate areas of the Southern Hemisphere, including southern South America, southernmost Africa, New Zealand, Australia and New Caledonia. Joseph Dalton Hooker was the first to notice similarities in the flora and speculated that Antarctica had served as either a source or a transitional point, and that land masses now separated might formerly have been adjacent.

<i>Dicksonia</i> Genus of ferns

Dicksonia is a genus of tree ferns in the order Cyatheales. It is regarded as related to Cyathea, but is considered to retain more primitive traits, dating back at least to the Jurassic and Cretaceous periods. The fossil record includes stems, pinnules, and spores.

Atherospermataceae Family of flowering plants

The Atherospermataceae, commonly known as the southern sassafrases, are a family of broadleaf evergreen trees and shrubs. The family includes 14 species in seven genera. The atherosperms are today mostly distributed in the Southern Hemisphere, with two species native to southern Chile and 12 species native to Australasia. Wood is commercially harvested from rainforest species of this family, and is used both in construction and in fine cabinet making.

Pergidae Family of insects

The Pergidae are a moderate-sized family of sawflies occurring in the Western Hemisphere and the Australasian Region. The Pergidae are, with almost 450 described species, the third-largest family of Symphyta after the Tenthredinidae and the Argidae. Morphologically, most pergids are typically sawfly-like, but the form of the antennae varies considerably in number of segments and from simple to serrate and pectinate or even bipectinate. Sexual dimorphism is common and reflected in differences in type of antennae, colour, and size. Included are some of the few known apterous sawflies, those of the genus Cladomacra occurring in Papua New Guinea and Indonesia, and a species with brachypterous females, Clarissa tasbates, in Tasmania.

<i>Uncinia</i> Genus of grass-like plants

Uncinia is a genus of flowering plants in the family Cyperaceae, known as hook-sedges in Australia and as hook grasses or bastard grasses in New Zealand. The genus is characterised by the presence of a long hook formed by an extension of the rachilla, which is used to attach the fruit to passing animals (epizoochory), especially birds, and it is this feature which gives the genus its name, from the Latin uncinus, meaning a hook or barb.

French ship <i>Astrolabe</i> (1811)

Astrolabe was a horse barge converted to an exploration ship of the French Navy and was originally named Coquille. She is famous for her travels with Jules Dumont d'Urville. The name derives from an early navigational instrument, the astrolabe, a precursor to the sextant.

Antarctic Floristic Kingdom Geographic area with a relatively uniform composition of plant species in the Antarctic

The Antarctic Floristic Kingdom, also the Holantarctic Kingdom, is a floristic kingdom that includes most areas of the world south of 40°S latitude. It was first identified by botanist Ronald Good, and later by Armen Takhtajan. The Antarctic Floristic Kingdom is a classification in phytogeography, different from the Antarctic realm classification in biogeography, and from Antarctic flora genera/species classifications in botany.

Paleotropical Kingdom

The Paleotropical Kingdom (Paleotropis) is a floristic kingdom comprising tropical areas of Africa, Asia and Oceania, as proposed by Ronald Good and Armen Takhtajan. Part of its flora, inherited from the ancient supercontinent of Gondwana or exchanged later, is shared with the Neotropical Kingdom, comprising tropical areas of Central and South America. Moreover, the Paleotropical flora influenced the tropical flora of the Australian Kingdom. The Paleotropical Kingdom is subdivided into five floristic subkingdoms according to Takhtajan and about 13 floristic regions. In this article the floristic subkingdoms and regions are given as delineated by Takhtajan.

<i>Arkys</i> Genus of spiders

Arkys, also known as triangular spider or ambush spider, is a genus of Australian araneomorph spiders in the family Arkyidae, first described by Charles Athanase Walckenaer in 1837. They are often small, with a triangular shaped abdomen, and are found in Australia and some of its surrounding islands. They don't build webs, but can often be found on leaves and tips of flower heads. Their egg sacs are pinkish-orange and spherical, and are made late in the summer.

Ecology of Tasmania

The biodiversity of Tasmania is of exceptional biological and paleoecological interest. A state of Australia, it is a large South Pacific archipelago of one large main island and a range of smaller islands. The terrain includes a variety of reefs, atolls, many small islands, and a variety of topographical and edaphic regions on the largest island, all of which promote the development of unusually concentrated biodiversity. During long periods geographically and genetically isolated, it is known for its unique flora and fauna. The region's climate is oceanic.

Arkyidae Family of spiders

Arkyidae is a family of araneomorph spiders first described by Ludwig Carl Christian Koch in 1872 as a subfamily of Araneidae, and later elevated to a full family in 2017.

<i>Galumna</i> Genus of mites

Galumna is a genus of mite in the family Galumnidae.
