A born naturalist and a fearless traveler, Vladimir Dinets wrote travel guides, conducted field research, and lived a couple of lives before he was accepted into the PhD program in zoology at the University of Miami.

Boyd Varty had an unconventional upbringing. He grew up on Londolozi Game Reserve in South Africa, a place where man and nature strive for balance, where perils exist alongside wonders.
