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.
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.
This reduction in genetic diversity was correlated with defects that include lower sperm quality, abnormal testosterone levels, cowlicks, and kinked tails. [16] In response, a genetic rescue plan was put in motion and several female pumas from Texas were introduced into the Florida population.
The Tanoli (Hindko/Urdu: تنولی، تناولی) are a Hindkowan tribe living mainly in the Hazara area of Khyber Pakhtunkhwa, Pakistan. [1] [2] They form the majority of the population of Lassan Nawab union council. [3] The Tanoli describe themselves as Barlas Turks. They never submitted to the British colonial rule in the 1840s.
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.
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 ...
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.
Evolutionary rescue is distinct from demographic rescue, where a population is sustained by continuous migration from elsewhere, without the need for evolution. [13] On the other hand, genetic rescue , where a population persists because of migration that reduces inbreeding depression, can be thought of a special case of evolutionary rescue ...
