...plasm bank An establishment concerned primarily with the conservation of hereditary genetic material which may be lost through the process of genetic erosion . Germ plasm loss is a major concern in Asia, parts of Africa, southern Europe, and countries bordering the Mediterranean, where antiquated cultivars are rapidly replaced by new varieties. With the loss of older cultivars, qualities possessed by them may be lost permanently, and so cannot become incorporated in new varieties. Gene banks are an important source of germ...

In 1928 he was appointed professor of zoology (and in 1931 also of oceanography) at University College Hull; in 1942 regius professor of natural history at the University of Aberdeen; and in 1945 Linacre...

This might involve migration between islands, up mountain slopes, and between mountain tops. The term was coined in 2004 by Brian Keel . 2 A technique used to establish a population of migratory animals in an area they did not formerly inhabit. For example, several groups of whooping cranes ( Grus americana ) raised in isolation from...

It stores, in a viable form, material from plants that are in danger of extinction in the wild and cultivars which are not currently in popular use. The stored genetic information can be called upon when required. For example, a crop may be needed that possesses a quality (e.g. tolerance to adverse climatic conditions) which cannot be found in currently exploited cultivars but was present in more antiquated varieties. The normal method of storage is to reduce the...

Feedback mechanisms between the biotic and abiotic elements of the biosphere will tend to create stable conditions in which major environmental change is dampened. The resulting...

...Owen cautiously began to formulate a theory of theistic evolution, arguing that individual species had come into existence by a preordained process of natural laws, for example, in his On the Nature of Limbs ( 1849 ).This view met with strong criticism from the Anglican establishment, and for much of the 1850s Owen remained a closet evolutionist. In the wake of Charles Darwin's Origin of Species ( 1859 ), however, he went public with his so-called derivative hypothesis, first in a Monograph on the Aye-aye ( 1863 ) and later in such other publications...

...husbandry may therefore significantly influence, and even possibly accelerate, the evolution of influenza. Once introduced, the success of the pathogen in a new population depends on its establishment and dissemination within the population. Many zoonotic introductions are highly virulent and not readily transmissible from person to person, preventing their establishment. Both the evolutionary potential of the pathogen and chance will play a role in whether the infection will be able to establish itself. An analytic framework was developed by Anderson and...
