Question

Eample of four factors that may limit the geographic disturbution of a species

Answer 1

1. If the species needs a lot of water and its habitat is surrounded by deserts.
2. If the species lives on an island and can't readily cross to the mainland. The Channel Islands off southern California have a lot of species that don't exist on the mainland.
3. If the species can't tolerate much water, it won't spread to where there is much rainfall. (I've noticed that in Southern California, a semi-desert climate, native lizards tend to disappear from frequently-watered neighborhoods. On the other hand, the garden snails that plague the residents there are an imported species that needs more water. They don't spread into wild areas because they can't survive there.)
4. If the species can't tolerate temperatures above or below a certain range, it won't spread beyond that. For instance, if you take a tropical animal to the temperate zone, it won't survive long or become established.
5. If the species requires a chill factor to reproduce, you can take it to a warmer climate, but it won't reproduce there. Some plants need a certain amount of time at a certain low temperature, or they won't flower or produce seeds.
