From: Genomic analysis reveals limited hybridization among three giraffe species in Kenya
Demographic history of Nubian, reticulated, and Masai giraffe s. str. Population size changes over the recent past were reconstructed from the site frequency spectrum (SFS) using the stairway plot model after masking singletons. Axes were scaled by a mutation rate of 2.12 × 10−8 substitutions per site per generation and a generation time of 10 years. Colors represent focal giraffe taxa. Solid lines indicate median Ne estimates, and shaded areas correspond to 95% confidence intervals. Estimates were based on 200 subsamples of the SFS
