The Kalahari: not somewhere you'd want to live to be honest

POTENTIAL for Species Increase in Kalahari/Leopard PREDATION
One species of leopard in the Kalahari –extremely rare with a dangerously small population size– shows up in the Africa TV series' first episode, and struggles to catch prey. It's a dangerous life they live, because in the kalahari, every kill counts. A meal missed implies less energy for the next one, and these animals live from meal to meal. This difficulty to survive is in itself, already enough of a threat; the low water count with a sparse, seemingly barren land proves to be an environment that does not allow for species increase for these leopards.
Rhinos and Sexual Reproduction
This, while not being a direct sexual dysfunction, did not please the female, and would probably hinder the male in the future with possible mates. If the rhino is unable to copulate, he will be unable to pass on his genes. He would prove himself to be weak. Maybe later, the female would find a superior male mate who would introduce more genetic variation into the species.
