A study by Namibian scientist Saima Shikesho reveals that black-backed jackals in Namibia urinate on sweet melons in the Namib Desert to deter other jackals from stealing their favourite fruit. These jackals play a key role in the propagation of the nara plant, a desert shrub that produces these melons, as their less developed molars allow the seeds to pass through them intact. The study also found that jackals visited the plants over 96% of the time, compared to other carnivores.
