  1. Peripatric speciation

    Evolutionary biology Image Speciation modes.svg left thumb 300px Comparison of allopatric speciation allopatric , peripatric, parapatric speciation parapatric and sympatric speciation sympatric speciation . Peripatric and peripatry are terms from biogeography , referring to organism s whose ranges are closely adjacent but do not overlap, being separated where these organisms do not occur &ndash for example a wide river or a mountain range. 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. One possible consequence of peripatric speciation is that a geographically widespread ancestral species becomes paraphyletic , thereby becoming a paraspecies . The concept of a paraspecies is therefore a logical consequence of the Evolutionary Species Concept, by which one species give rise to a daughter species.

  1. Speciation of ions

    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.

  1. Hybrid swarm

    unsourced date November 2011 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 hybrid speciation , 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 eo Hibrida svarmo ...   more details



  1. Speciation (genetic algorithm)

    unreferenced date December 2007 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.

  1. Hybrid seed

    Unreferenced date December 2009 In agriculture and gardening , hybrid seed is seed produced by pollination cross pollinated plant s. In hybrid seed production, the crosses are specific and controlled. The advantage of growing hybrid seed compared to inbred lines comes from heterosis . To produce hybrid seed, elite inbred varieties with well documented and consistent phenotypes such as yield are crossed and the resulting hybrid seed is collected. Another factor that is important in hybrid seed production is the combining ability of the parent plants. Although two elite inbred parent plant varieties may produce the highest yields of their crop, it does not necessarily mean that crossing these inbreds will result in the highest yielding hybrid. Combining ability is the term used to describe the level of heterosis that the parents will generate in the resultant seed. Higher combining ability between the parents results in increased performance in the resulting hybrid seed. 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. Today, hybrid seed production is predominant in agriculture and home gardening, and is one of the main contributing factors to the dramatic ... was launched in the 1920s, with the first hybrid maize . All of the hybrid seeds planted by the farmer will be the same hybrid, which causes the first generation of seed from the hybrids planted to be inbred.
