Experimental evidence that updrafts and turbulence hinder the ability of predators to find prey using olfaction

A major assumption of the olfactory concealment theory is that olfactory predators should have greater difficulty finding prey where updrafts and turbulence occur. One way to test this assumption is to create updrafts or horizontal turbulence at a specific location and then compare how quickly an olfactory predator can locate prey in such areas versus a control area where airflow is more laminar. I tested this in three experiments using domestic dogs and free-ranging predators.
