When applied topically, cayenne pepper benefits the skin, too. It alleviates pain caused by shingles, osteoarthritis, rheumatoid arthritis and even as part of a natural remedy for fibromyalgia. The fruit of the capsicum plant contains a chemical called capsaicin.
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.

Best Answer: Temporal isolation is a prezygotic barrier in which the two species reproduce at different times of the day, season, or year.Wood and leopard frogs are an example of two similar species whose ranges overlap.Habitat isolation is a prezygotic barrier in which two species whose ranges overlap live in different habitats. As a result, potential mates from the two species do not encounter one another.hree other prezygotic barriers are behavioral isolation, mechanical isolation, and gametic isolation. In behavioral isolation, reproduction between similar species is prevented because each group possesses its own characteristic courtship behaviors.
