Examples of Mechanical Isolation. Mechanical isolation is very common in plants. For example, flowering plants that do not have the correct shape for a pollinator will not receive a pollen transfer, and will therefore not be fertilized.In this case, the shape is the barrier. But keep in mind that mechanical isolation is not always so clear-cut.Think of a Great Dane and a Chihuahua.or example, flowering plants that do not have the correct shape for a pollinator will not receive a pollen transfer, and will therefore not be fertilized.
