Tests on wild cheetahs have shown that there is low genetic diversity among individuals. Wildlife biologists and conservationists are worried about what this means for the survival of this species.  Why is low genetic variability a big problem when it comes to a species survival in a changing habitat?

Conservation Biology

The study of how to prevent the loss of biological diversity on the planet is called conservation. Biological diversity, also termed biodiversity, consists of various life forms found in a specific location or across the entire planet, including ecosystems, species, populations, and genes. Conservation thus aims to protect the diversity of life at all levels of biological organization.
