Describe the different types of isolation and give a specific example of each isolation?

1. Habitat Isolation. Two species may live in the same area but in different habitats. Living in these different habitats ( in water, living on land, or living in tree tops) effectively segregate these organisms from each other. Since there is little if any contact the possibility of successfully mating is drastically reduced.





2. Temporal Isolation. Two species that breed at different times of the day, season, or year cannot mix their gametes. Since the breeding times are different there is no chance of reproductive contact.





3. Behavioral Isolation. Species-specific signals and elaborate behavioral patterns are used by closely related species to insure contact with the proper mate. Birds, mammals, and insects have pre-mating rituals that attract the proper mate. These signals can be chemical or physical in nature. Other organisms pay little or no attention to these behaviors or scents.





4. Mechanical Isolation. Anatomical incompatibility may prevent sperm transfer between two closely related species. The absence of certain appendages or their modification may inhibit a male from grasping and successfully fertilizing the female. Difference in floral structure may prevent pollen from reaching the stigma of the intended flower.





5. Gametic Isolation. If for some reason foreign sperm is introduced into a female there are several preventative measures to insure that there is no union between the sperm and egg. Internal environmental conditions may cause the sperm to die. Gamete recognition sites on the sperm do not fit with the intended egg. If the two species differ in the type of fertilization (external and internal) there is no chance of the sperm ever contacting the egg.Describe the different types of isolation and give a specific example of each isolation?
Are you talking about evolution and speciation?





The two main types are


1. Geographic isolation: a population is separated by distance or some kind of barrier so the members of the population can't interbreed with the main population. For example, animals stranded on an island can't interbreed with populations from the mainland anymore - honeycreepers on the Hawaiian Islands or marine iguanas on the Galapagos.


2. Reproductive isolation: members of a population do not interbreed with others for some reason. For instance, a few members of a frog population began to breed in the fall instead of in the spring. These frogs were reproductively isolated from the rest of the population because there was no further interbreeding. Any changes that accumulated in the two groups stayed within their group and was not shared with the other group. Over time they can become different species. Other ways reproductive isolation can happen are: breeding in different places (in the tree branches vs on the ground) and changes in reproductive anatomy so interbreeding is not physically possible. In all of these cases, the two populations can live in the very same place and still be isolated reproductively.Describe the different types of isolation and give a specific example of each isolation?
