Habitat isolation occurs when two species live in the same area but encounter each other rarely, or not at all, because they occupy different habitats. This prevents them from mating. Similarly, dog breeders maintain the purity of breeds (prevent different breeds from mating) by physically keeping them apart, which is analogous to how habitat isolation works in nature.
