Key Concepts

Genetic Diversity

Genetic diversity refers to the total number of genetic characteristics in the genetic makeup of a species. It enables populations to adapt to environmental changes and resist pathogens, ensuring long-term survival. Low genetic diversity can make a population vulnerable to diseases and reduce adaptability, which is a critical concern for endangered species.

Extinction Vortex

The extinction vortex is a process where small populations become subject to a set of reinforcing factors, such as inbreeding depression and reduced genetic diversity, that further decrease their numbers and can lead to extinction. This feedback loop makes recovery difficult, thus rapid interventions are critical to reverse or halt the spiral toward extinction.

Genetic Rescue

Genetic rescue involves introducing new genetic material into a small, isolated, or inbred population, thereby increasing genetic diversity and fitness. This process can reduce the negative effects of inbreeding and bolster the population's ability to adapt to environmental changes, ultimately improving its survival prospects.
