==Behavioral characteristics== Musth is believed to be linked to [[sexual arousal]] or establishing [[Dominance hierarchy|dominance]].<ref name=Sukumar />{{rp|101}} Wild bulls in musth often produce a characteristic low, pulsating [[elephant communication|rumbling noise]] known as "musth rumble" which other elephants can hear from miles away. The rumble has been shown to prompt not only attraction in the form of reply vocalizations from cows in heat, but also silent avoidance behavior from other bulls, particularly juveniles and non-receptive females, suggesting an evolutionary benefit to advertising the musth state.<ref name="slotow">Rob Slotow, Dave Balfour, and Owen Howison.[https://web.archive.org/web/20080227081853/http://www.iucn.org/themes/ssc/sgs/afesg/pachy/pdfs/pachy31.pdf#page=17 "Killing of black and white rhinoceroses by African elephants in Hluhluwe-Umfolozi Park, South Africa"], ''Pachyderm'' 31 (July–December, 2001):14–20.

This was ultimately attributed to an aberrant form of musth. After being rebuffed by older female elephants, they went after rhinos, killing them after raping some. Three young elephant bulls were shot which temporarily ended the killings.<ref>[https://archive.seattletimes.com/archive/19941023/1937416/a-murder-mystery-why-were-elephants-slaughtering-rhinos----lack-of-adult-role-models-gets-the-blame A Murder Mystery: Why Were Elephants Slaughtering Rhinos?], seattletimes.com.

These young bulls had been spared themselves due to their age and size although herd culls are properly done in entirety, i.e. leaving no survivors to suffer the equivalents of PTSD, survivor guilt, and other disorders or traumas later in life which can then create or exacerbate human-elephant conflicts or other forms of violence, according to Ron Thomson, a late 20th-century [[Zimbabwe]] game warden and Parks Board veteran.<ref>[https://africageographic.com/stories/kruger-cull-88-elephants-says-hunter-ron-thomson/ Kruger should cull 88% of its elephants, says hunter Ron Thomson], africageographic.com.

It is established that functionally important decision-making abilities may be significantly altered by disruption of the natural structure of kin-based social relationships and that violent disruption "appears capable of driving aberrant behaviours in social animals that are akin to the [[PTSD|post-traumatic stress disorder]] experienced by humans following extremely traumatic events" due to the pachyderms' intelligence, strong emotional family attachments, and prodigious memories.<ref>[https://frontiersinzoology.biomedcentral.com/articles/10.1186/1742-9994-10-62#:~:text=However%2C%20extremely%20disruptive%20events%2C%20including,individual's%20close%20social%20bonds%20and Effects of social disruption in elephants persist decades after culling], frontiersinzoology.biomedcentral.com. 23 October 2013.
