The Slotow Effect (When Young Male Have No Elders)

In the late 1990s, rangers in South Africa started finding dead rhinos, gored and trampled with a level of violence that didn't match anything on record. The killers weren't poachers. They were elephants. By 1997, at Pilanesberg National Park, at least forty white rhinos had been killed this way, all by young male elephants relocated years earlier without a single adult present. What wildlife biologist Rob Slotow discovered didn't just explain a strange animal behavior. It exposed something about how violence gets made in the first place, and how it can be undone. In this video, we explore how removing an entire generation of elder elephants triggered a wave of dysregulated aggression, why the introduction of six older bulls stopped the killings almost overnight, and why researchers keep finding the same underlying pattern echoing far outside the reserve fence. 00:00 The dead rhinos 00:52 The relocation decision 01:57 What musth reveals 03:20 The older bulls arrive 04:32 The wider pattern Sources and further reading linked in comments.
