Do weather, convection, isolated surface features, or shelterbelts influence nest predation rates of olfactory predators?
When the air is completely still, odor plumes emanating from nests will be circular and short. This will reduce the probability of an olfactory predator intercepting the odor plume while hunting compared to when the odor plume is long and narrow. Furthermore, an olfactory predator will have a harder time finding nests when the air is still because the predator cannot locate the nest by simply moving upwind. Unfortunately, no studies have compared the probability of a nest surviving a night when there is no wind to when there is a breeze, but this would be easy to test using captive predators.
