Reticulation or Reticulated may refer to: * Reticulation (single-access key), a structure of an identification tree, where there are several possible routes to a correct identification * A coloration pattern of some animals (e.g. the reticulated giraffe) * An arrangement of veins in a leaf, with the veins interconnected like a network * The endoplasmic reticulum within a cell, often resembling a net * A phylogenetic network, the result when hybrid speciation, introgression and parapyletic speciation is applied to a phylogenetic tree * Reticulated water (Australia, South Africa), water from a piped network rather than from a bore or well, see: wiktionary:reticulated water *Reticulation (metalwork), a decorative technique in metalworking See also * Reticular (other) Reticular describes a set of connective tissue, fibers, etc., in network form such as with cross-link bonds.

Net (device)
Nets have been constructed by human beings since at least the Mesolithic period for use in capturing or retaining things. Their open structure provide lightness and flexibility that allow them to be carried and manipulated with relative ease, making them valuable for methodical tasks such as hunting, fishing, sleeping, and carrying. Definition A net, in its primary meaning, comprises threads or yarns knotted and twisted into a grid-like structure which blocks the passage of large items, while letting small items and fluids pass. It requires less material than something sheet-like, and provides a degree of Transparency and translucency, transparency, as well as flexibility and lightness. History The oldest nets found are from the Mesolithic era, but nets may have existed in the Upper paleolithic, Upper paleolithic era. Nets are typically made of perishable materials and leave little archeological record. Some nets are preserved in ice or bogs, and there are also Use of animals ...

Reticulation (single-access Key)
In biology, a reticulation of a single-access identification key connects different branches of the identification tree to improve error tolerance and identification success. In a reticulated key, multiple paths lead to the same result; the tree data structure thus changes from a simple tree to a directed acyclic graph. Two forms of reticulation can be distinguished: Terminal reticulation and inner reticulation. * In a terminal reticulation a single taxon or next-level-key is keyed out in several locations in the key. This type of reticulation is normally compatible with any printable presentation format of identification keys and normally does not require special precautions in software used for branching keys. * In an inner reticulation a couplet with further leads can be reached through more than one path. Depending on the software or printable presentation format, this may be more challenging. For the linked (= "parallel" or "bracketed") format, where each lead points to a nu ...

Reticulated Giraffe
The reticulated giraffe (''Giraffa camelopardalis reticulata'' or ''G. reticulata''), also known as the Somali giraffe, is a subspecies or species of giraffe native to the Horn of Africa. It lives in Somalia, southern Ethiopia, and northern Kenya.Rare white giraffes spotted in Kenya conservation area . Naaman Zhou, , 14 September 2017. Accessed 14 September 2017. There are approximately 8,500 individuals living in the wild. Reticulated giraffes can interbreed with other giraffe species in captivity or if they come into contact with populations of other species in the wild ...

Venatious
A leaf (plural, : leaves) is any of the principal appendages of a vascular plant plant stem, stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthesis, photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (Glossary of botanical terms#adaxial, adaxial) and lower (Glossary of botanical terms#abaxial, abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endoplasmic Reticulum
The endoplasmic reticulum (ER) is, in essence, the transportation system of the eukaryotic cell, and has many other important functions such as protein folding. It is a type of organelle made up of two subunits – rough endoplasmic reticulum (RER), and smooth endoplasmic reticulum (SER). The endoplasmic reticulum is found in most eukaryotic cells and forms an interconnected network of flattened, membrane-enclosed sacs known as cisternae (in the RER), and tubular structures in the SER. The membranes of the ER are continuous with the outer nuclear membrane. The endoplasmic reticulum is not found in red blood cells, or spermatozoa. The two types of ER share many of the same proteins and engage in certain common activities such as the synthesis of certain lipids and cholesterol. Different types of cells contain different ratios of the two types of ER depending on the activities of the cell. RER is found mainly toward the nucleus of cell and SER towards the cell membrane or plasma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetic Network
A phylogenetic network is any graph used to visualize evolutionary relationships (either abstractly or explicitly) between nucleotide sequences, genes, chromosomes, genomes, or species. They are employed when reticulation events such as hybridization, horizontal gene transfer, recombination, or gene duplication and loss are believed to be involved. They differ from phylogenetic trees by the explicit modeling of richly linked networks, by means of the addition of hybrid nodes (nodes with two parents) instead of only tree nodes (a hierarchy of nodes, each with only one parent). Phylogenetic trees are a subset of phylogenetic networks. Phylogenetic networks can be inferred and visualised with software such as SplitsTree, the R-package, phangorn, and, more recently, Dendroscope. A standard format for representing phylogenetic networks is a variant of Newick format which is extended to support networks as well as trees. Many kinds and subclasses of phylogenetic networks have been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reticulation (metalwork)
In metalwork, reticulation refers to a decorative surface finishing technique involving the application of localised heat to the surface of a metal object. Reticulation is typically performed on alloys of silver and copper or of gold and copper. Reticulation exploits the difference between the melting temperature of an unalloyed metal and that of an alloy of the metal; by depleting the base metal A base metal is a common and inexpensive metal, as opposed to a precious metal such as gold or silver. In numismatics, coins often derived their value from the precious metal content; however, base metals have also been used in coins in the past ... content in the surface layer, a piece can be heated in such a manner so as to render the interior of the piece molten while leaving the surface of the piece intact. The reticulated surface is formed by the thermal expansion and contraction of the interior metal which is effected by deliberate variation in the application of localised heat. ...
