Genetic signatures of population bottlenecks, relatedness, and inbreeding highlight recent and novel conservation concerns in the Egyptian vulture

The assessment of temporal variation in genetic features can be particularly informativeon the factors behind demography and viability of wildlife populations and species. Weused molecular methods to evaluate neutral genetic variation, relatedness, bottlenecks,and inbreeding in a declining populatio...
