Abrotanella Caespitosa
Abrotanella caespitosa is a member of the Asteraceae, daisy family and is an endemism, endemic species of the South Island of New Zealand. Description ''Abrotanella caespitosa'' forms a loose cushion habit (biology), habit with Runners (botany), runners that have distant scale leaves. It has narrower leaves compared to its close relatives and lacks a waxy Epicuticular wax, bloom on its leaves. Distribution and habitat The species is found in the South Island of New Zealand, with recorded populations in Southland Region, Southland (The Remarkables) and Otago (Rock and Pillar Range). It grows in alpine herbfield habitats. Taxonomy and evolution ''Abrotanella caespitosa'' is closely related to ''Abrotanella , A. inconspicua'', ''Abrotanella nivigena, A. nivigena'' (from Australia), and ''Abrotanella patearoa, A. patearoa''. These four species form a well-supported clade and have almost identical DNA sequences, suggesting they diverged within the last 500,000 year ...

Donald Petrie (botanist)
Donald Petrie (7 September 1846 – 1 September 1925) was a Scottish botanist noted for his work in New Zealand. Petrie was born in the parish of Edinkillie, Moray, on 7 September 1846 and educated at Aberdeen Grammar School and the University of Aberdeen. He taught at the Glasgow Free Church Training College, the Glasgow Academy and Scotch College in Melbourne, Australia, before being appointed inspector of schools with the provincial government in Otago, New Zealand, in October 1873. An active member of the Otago Institute, Petrie was elected a fellow of the Linnean Society of London (1886) and served as president of the Auckland Institute Auckland (pronounced ) ( mi, Tāmaki Makaurau) is a large metropolitan city in the North Island of New Zealand.

Abrotanella
''Abrotanella'' is a genus in the family Asteraceae, of 23 species, native to Australia, New Zealand and southern South America. They are usually small plants, sometimes not reaching more than a few millimetres above the ground, although some form cushions in bolster heaths reaching up to a metre in diameter. Taxonomy Genus ''Abrotanella'' is placed in the tribe Senecioneae and is the sole genus in the subtribe Abrotanellinae. The genus was formerly placed in the subtribe Blennospermatinae, but molecular and morphological studies have shown it to be distinct from other genera in that group. Phylogenetic studies have shown that Abrotanella forms a well-supported monophyletic group. It is sister to a clade formed by three other genera: '' Crocidium'', ''Blennosperma'', and '' Ischnea''. Within ''Abrotanella'', '' A. forsteroides'' from Tasmania is sister to all other species in the genus. Evolutionary history The evolutionary history of ''Abrotanella'' has been inv ...

Flora Of The South Island
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of New Zealand
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] |

Glaciation
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the most recent glacial period ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

DNA Sequence
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery. Knowledge of DNA sequences has become indispensable for basic biological research, DNA Genographic Projects and in numerous applied fields such as medical diagnosis, biotechnology, forensic biology, virology and biological systematics. Comparing healthy and mutated DNA sequences can diagnose different diseases including various cancers, characterize antibody repertoire, and can be used to guide patient treatment. Having a quick way to sequence DNA allows for faster and more individualized medical care to be administered, and for more organisms to be identified and cataloged. The rapid speed of sequencing attained with modern D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...
