Learn about lion genetics in this clip from Gorongosa Park: Rebirth of Paradise. Paola Bouley arrives to solve this baffling mystery: with so much prey to eat, why is Gorongosa's lion population not growing as fast as it should? Because lions are an important keystone species in the ecosystem, and a big draw for tourists, their recovery is critical to the success of the entire restoration effort. To find the answer, Bouley first needs to identify the lions. Creating a database allows her to accurately keep track of exactly how many lions there are. With so few lions, Paola fears the gene pools are limited. This genetic bottle necking makes the lions susceptible to genetic abnormalities, the robustness of the population is reduced and its ability to survive environmental changes, like climate change or a shift in available resources, is reduced.
