Other climatic factors may limit the insect to a smaller range within the host plant range; for example, selection of food plants by the desert species of sugar-beet leafhopper depends on the abundance of rainfall during one season.
39 When available, internal validation data from the study of interest are the recommended data to inform the values used for sensitivity analysis, so long as the internal validation study itself was not biased by, for example, selection of subjects into the validation substudy.
The printing trade, for example, introduced selection by objective testing of suitability and aptitude, while the motor-vehicle-repair industry developed an apprenticeship scheme for a national craftsman's certificate.
For example, cultivar selection by growers disrupts plant pathogen coevolution (Bousset and Chèvre 2013).
Though the greyhound was an example of careful selection by domestic breeders, Darwin imagined the dog as natural and thus offered one of his most profound metaphors: a dog that straddled the natural and domestic worlds, at once appearing intelligent and emotional like man, but physically ever the feral predator.
For each allele, an equilibrium frequency exists that can be shifted, for example by selection; however, it will be restored after the end of the selection.
Such change could be driven for example by selection against maladaptive hybridization, a phenomenon known as reproductive character displacement or reinforcement.
An example is provided: habitat selection by wild boar is studied in a Mediterranean habitat using the K-select analysis.
This article provides a reliable, robust example of how natural selection by predation operates in the wild and strongly supports the paradigm that predators kill substandard individuals.
One such process is standardisation by selection and examples include selecting by body type or focusing on a single body part.
