Template Evolutionary biology Hybridspeciation is the process wherein Hybrid biology hybridization between two different closely related species leads to a distinct phenotype . This phenotype in very rare cases can also be fitter than the parental lineage and as such natural selection may then favor these individuals. Eventually, if reproductive isolation is achieved, it may lead to a separate species. However, reproductive isolation between hybrids and their parents is particularly difficult to achieve and thus hybridspeciation is considered an extremely rare event. Hybridization without change in chromosome number is called homoploid hybridspeciation. It is considered very rare but has been shown in Heliconius butterfly butterflies and in sunflower s. Polyploid speciation, which involves changes in chromosome number, is a more common phenomenon, especially in plant species.

Such organisms are usually closely related e.g. sister species , their distribution being the result of peripatric speciation . Peripatric speciation is a form of speciation , the formation of new species through evolution . In this form, new species are formed in isolated peripheral populations this is similar to allopatric speciation in that populations are isolated and prevented from exchanging genes. However, peripatric speciation, unlike allopatric speciation, proposes that one of the populations is much smaller than the other. Peripatric speciation was originally proposed by Ernst Mayr , and is related to the founder effect , because small living populations may undergo selection bottlenecks. ref cite journal author Provine WB title Ernst Mayr Genetics and speciation url http www.genetics.org cgi content full 167 3 1041 journal Genetics volume 167 issue 3 pages 1041 6 date 1 July 2004 pmid 15280221 pmc 1470966 ref Genetic drift is often proposed to play a significant role in peripatric speciation. ref cite journal author Templeton AR title The theory of speciation via the founder principle url http www.genetics.org cgi reprint 94 4 1011 journal Genetics volume 94 issue 4 pages 1011 38 date 1 April 1980 pmid 6777243 pmc 1214177 ref speciation show no evolution show no References Reflist DEFAULTSORT Peripatric Speciation Category Ecology Category Evolutionary biology Category Speciation Category Scientific classification Category Taxonomy pt Especia o perip trica ru ... more details
Speciation of ions refers to the changing concentration of varying forms of an ion as the pH of the solution changes. Image Weak acid speciation3.png thumb 200px right The ratio of acid, AH and conjugate base, A sup &minus sup , concentrations varies as the difference between the pH and the p K sub a sub varies, in accordance with the Henderson Hasselbalch equation . The pH of a solution of a monoprotic weak acid can be expressed in terms of the extent of dissociation. After rearranging the expression defining the acid dissociation constant , and putting pH log sub 10 sub H sup sup , one obtains pH p K sub a sub log AH A sup sup This is a form of the Henderson Hasselbalch equation . It can be deduced from this expression that when the acid is 1 dissociated, that is, when AH A sup sup 100, pH p K sub a sub 2 when the acid is 50 dissociated, that is, when AH A sup sup 1, pH p K sub a sub when the acid is 99 dissociated, that is, when AH A sup sup 0.01, pH p K sub a sub 2 It follows that the range of pH within which there is partial dissociation of the acid is about p K sub a sub 2. This is shown graphically at the right. A practical application of these results is that the pH transition range of a pH indicator is approximately p K sub a sub 1 the colour of the indicator in its acid form is different from the colour of the conjugate base form. In the transition range both forms are in equilibrium, so the colour is intermediate. Outside the transition range the concentration of acid or conjugate base is less than 10 and the colour of the major species dominates.

Multiple issues unreferenced December 2007 orphan November 2006 Speciation is a process that occurs naturally in evolution and is modeled explicitly in some genetic algorithms . Speciation in nature occurs when two similar reproducing beings evolve to become too dissimilar to share genetic information effectively or correctly. In the case of living organisms , they are incapable of mating to produce offspring . Interesting special cases of different species being able to breed exist, such as a horse and a donkey mating to produce a mule . However in this case the Mule is usually infertile, and so the genetic isolation of the two parent species is maintained. In implementations of genetic search algorithms, the event of speciation is defined by some mathematical function that describes the similarity between two candidate solutions usually described as individuals in the population. If the result of the similarity is too low, the chromosomal crossover crossover Operation mathematics operator is disallowed between those individuals.

A hybrid swarm is a population of hybrid biology hybrid s that has survived beyond the initial hybrid generation, with interbreeding between hybrid individuals and backcrossing with its parent types. Such population are highly variable, with the genetic and phenetic characteristics of individuals ranging widely between the two parent types. Hybrid swarms thus blur the boundary between the parent taxa. Hybrid swarms occur when the hybrid is viable and at least as hybrid vigour vigorous as its parent types and there are no barriers to crossbreeding between the hybrid and parent types. Swarms cannot occur if one of these conditions is not met if the hybrid type has low viability, the hybrid population cannot maintain itself except by further hybridisation of the parent types, resulting in a hybrid population of low variability. On the other hand, if hybrids are vigorous but cannot backcross with parent populations, the result is a new hybrid taxon , which, aside from the contribution of new hybrids, evolves independently of its parent types. biology stub Category Hybridisation biology Category Population genetics cs Hybridn roj ... more details

Context date October 2009 In automata theory , a hybrid automaton plural hybrid automata or hybrid automatons is a mathematical model for precisely describing systems in which computational processes interact with physical processes. The behavior of a hybrid automaton consists of discrete state transition s and continuous evolution. Examples A simple example is a room thermostat heater system where the temperature of the room evolves according to laws of thermodynamics and the state of the heater on off the thermostat senses the temperature, performs certain computations and turns the heater on and off. In general, hybrid automata have been used to model and analyze a variety of embedded systems including vehicle control system s, air traffic control systems, mobile robots , and processes from systems biology . Definition Informally, a hybrid automaton is a possibly infinite state machine augmented with differential equations . It is a standard model for describing a hybrid system . Several different but equivalent formal definitions exist. Related models Hybrid automata come in several flavors The Alur Henzinger hybrid automaton is a popular model it was developed primarily for algorithmic analysis of hybrid systems model checking . The http www cad.eecs.berkeley.edu tah HyTech HyTech model checking tool is based on this model. The Hybrid Input Output Automaton model has been developed more recently. This model enables compositional modeling and analysis of hybrid systems. Another formalism which is useful to model implementations of hybrid automaton is the lazy linear hybrid automaton .

The ICBN provides the following options in dealing with a hybrid A hybrid may get a normal botanical name this will usually be the option of choice for naturally occurring hybrids. A hybrid may also be indicated by a formula listing the parents. Such a formula uses the multiplication sign to link the parents. A hybrid name is usually reserved for horticulture horticulturally arising hybrids and plant breeding artificial and or forced hybrids . A hybrid name is indicated by a multiplication sign placed before the name or epithet, as the case may be. A hybrid name is a botanical name, and is treated like other botanical names, for most purposes. The multiplication sign is not part of the actual name and is to be disregarded for nomenclatural purposes such as synonym botany synonymy , homonym botany homonymy , etc. This means that, say, Drosera anglica for nomenclatural purposes is to be treated as Drosera anglica . A taxonomist could decide to use either form of this name, if he wants to emphasize that it is a hybrid he will use Drosera anglica , if he wants to emphasize that it is a species he will use Drosera anglica .

Unreferenced date December 2009 In agriculture and gardening , hybrid seed is seed produced by artificially pollination cross pollinated plant s. Hybrids are bred to improve the characteristics of the resulting plants, such as better crop yield yield , greater uniformity, improved color , disease resistance, and so forth.
