Genetic rescue is seen as a mitigation strategy designed to restore genetic diversity and reduce extinction risks in small, isolated and frequently inbred populations. [1] It is largely implemented through translocation, a type of demographic rescue and technical migration that adds individuals to a population to prevent its potential extinction.
Genetic pollution is a term for uncontrolled [1] [2] gene flow into wild populations. It is defined as "the dispersal of contaminated altered genes from genetically engineered organisms to natural organisms, esp. by cross-pollination", [3] but has come to be used in some broader ways.
Revive & Restore is a nonprofit wildlife conservation organization focused on use of biotechnology in conservation.Headquartered in Sausalito, California, the organization's mission is to enhance biodiversity through the genetic rescue of endangered and extinct species.
Population bottleneck followed by recovery or extinction. A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts; or human activities such as genocide, speciocide, widespread violence or intentional culling.
Genetic diversity on the population level is a crucial focus for conservation genetics as it influences both the health of individuals and the long-term survival of populations: decreased genetic diversity has been associated with reduced average fitness of individuals, such as high juvenile mortality, reduced immunity, [2] diminished ...
Conservation efforts for small populations at risk of extinction focus on increasing population size as well as genetic diversity, which determines the fitness of a population and its long-term persistence. [21] Some methods include captive breeding and genetic rescue. Stabilizing the variance in family size is an effective way can double the ...
He recognized that the official definition of PTSD failed to describe their mental anguish, leading him to coin the term “moral injury.” The ideals taught at Parris Island “are the best of what human beings can do,” said William P. Nash, a retired Navy psychiatrist who deployed with Marines to Iraq as a combat therapist.
The rescue effect is a phenomenon which was first described by Brown and Kodric-Brown, [1] and is commonly used in metapopulation dynamics and many other disciplines in ecology. This populational process explains how the migration of individuals can increase the persistence of small isolated populations by helping to stabilize a metapopulation ...
