A recent study investigated the impact of culling and relocation on elephant decision-making and cognition decades later. African elephants are highly intelligent and social creatures, and rely on their sophisticated communication skills to survive in the wild. How does the trauma of being separated from "loved ones" and their native terrain change how orphaned elephants think, and cope?
From a recent National Geographic article by Christy Ullrich Barcus:
Behavioral ecologists from the University of Sussex in England led an international team to study two different elephant populations: one relatively undisturbed group living in Amboseli National Park in Kenya and another translocated population in Pilanesberg Park in South Africa. The Pilanesberg elephants were moved there as calves following managed culling of adults and older juveniles in Kruger National Park in the 1980s and 1990s.
Survivors from the translocated elephant group showed signs of negative long-term psychological impact that affected their decision-making process, paralleling post-traumatic stress disorder (PTSD) in humans, according to the study, which was published in Frontiers in Zoology on October 23, 2013.
In other words, they experience PTSD in ways that are not entirely unlike human beings.
