Myrmecia Nigrocincta
''Myrmecia nigrocincta'', commonly known as the jumper ant or jumping jack, is an ant of the genus ''Myrmecia''. The species was first described by Frederick Smith in 1858. Colonies of this ant are abundant in eastern Australia. Ants of this species are known for their ability to jump up to 10 centimetres, and they also have a powerful, venomous sting. Rather than foraging on the ground, ''M. nigrocincta'' prefer to forage in trees where they are known to pollinate certain flowers. This ant is a large species, some workers can grow to over in length. They have a distinctive pattern of orange-red and black which distinguishes them from other ''Myrmecia'' species. ''M. nigrocincta'' possess the gamergates gene which allows workers to reproduce, either in the presence of a queen or in a colony where the queen is missing. Life expectancy of a worker ant is over one year. They are aggressive when attacking intruders. Distribution Abundant in eastern Australia, ''M. nigrocincta'' a ...

Frederick Smith (entomologist)
Frederick Smith (30 December 1805 – 16 February 1879) was a British entomologist who worked at the zoology department of the British Museum from 1849, specialising in the Hymenoptera. Smith was born near York to William Smith and went to school at Leeds. He then studied under landscape engraver W.B. Cooke along with his nephew William Edward Shuckard. Together they took an interest in insects, especially the ants and bees. In 1841, following the death of William Bainbridge, he became a curator of the collections and the library of the Entomological Society of London. As an engraver he produced copies based on the works of Turner, Constable and David Roberts. He also worked with Gray arranging Hymenoptera in the British Museum. In 1849 he succeeded Edward Doubleday as a member of the zoologicy department. He then gave up his art work but produced the plates for Wollaston's ''Insecta Maderensia'' (1854) and for papers in the Transactions of the Entomological Society. In 1875, h ...

Dorrigo, New South Wales
Dorrigo, a small town on the Waterfall Way, is located on the Northern Tablelands, in northern New South Wales, Australia. The town is part of Bellingen local government area. It is approximately north of the state capital, Sydney via the Pacific Highway, and west from the coastal city of Coffs Harbour. The town is situated on the Dorrigo Plateau near the New England Escarpment, which is part of the Great Dividing Range. Dorrigo is above sea level. At the 2016 census, Dorrigo had a population of 1,042 people. History The area now known as Dorrigo lies on the traditional land of the Gumbainggir people. European settlement of the area followed on from the early timber cutters in the 1860s. The first official European in the district was Land Commissioner Oakes who sighted the mouth of the Bellinger River. Dorrigo is derived from the Aboriginal word, ''dondorrigo'' or Dandarrga, meaning "stringy-bark". For many decades it was believed that explorer and settler Major Edward ...

Monophyly
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have taken ...

Paraphyly
In taxonomy, a group is paraphyletic if it consists of the group's last common ancestor and most of its descendants, excluding a few monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia ( reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancestor, including all extant reptiles as well as the extinct synapsids, ...

Phylogenetics
In biology, phylogenetics (; from Greek language, Greek wikt:φυλή, φυλή/wikt:φῦλον, φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, Protein, protein Amino acid, amino acid sequences, or Morphology (biology), morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An un ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

London
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia.

Syntype
In biological nomenclature, a syntype is any one of two or more biological types that is listed in a description of a taxon where no holotype was designated. Precise definitions of this and related terms for types have been established as part of the International Code of Zoological Nomenclature and the International Code of Nomenclature for algae, fungi, and plants. In zoology In zoological nomenclature, a syntype is defined as "Each specimen of a type series (q.v.) from which neither a holotype nor a lectotype has been designated rts. 72.1.2, 73.2, 74 The syntypes collectively constitute the name-bearing type." (Glossary of the zoological Code ). Historically, syntypes were often explicitly designated as such, and under the present ICZN this is a requirement (Art. 72.3), but modern attempts to publish species or subspecies descriptions based on syntypes are generally frowned upon by practicing taxonomists, and most are gradually being replaced by lectotypes. Those that still ex ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
