Native varieties expand and renew the crop genetic resources of developed countries while also performing well under the ecological and economic conditions of the traditional farms where they are grown. With agricultural modernization and

The Upheavals of the Second World War,tions have occurred on islands, and they are usually due to human-related disturbance. The effects of human-related disturbance are calibrated by measuring the rate of extinction for two sets of Holocene landbridge islands where human impact has been minimal. Extinction rates for islands with a hist

Diogo M. Souza-Monteiro,Neal H. Hookerthe combined effects of random genetic changes and demographic variation would likely result in extinction. One prerequisite to estimating such minimum viable population sizes is the determination of the effects of inbreeding on fitness. Two hypotheses make distinct predictions about the relative to

Considerations should be made of behavioral genetic, and ecological traits that might create greater or lesser vulnerability to extinction given the same human impacts. A brief consideration of t
