The body of the organism assumes that it is going to be in these new conditions for a short while only. They are just temporary variations to survive the new conditions. These differences among ecophenes and not permanent. You can see examples of this in humans as well an American living in Africa, and one living in northern Europe will have differences in the features. For example, a species of grass called Euphorbia hirta has two different ecophenes one that has adapted to grow in dry, hard soils and the other that grows in places that have been heavily trampled. For example, when a European comes to the tropics, the immediate response is increased production of melanin-his skin becomes darker. When a species is transported to a new environment, it’s first response will be to develop abilities to survive there. These are otherwise called ecads or morphologically-changed forms. Within this amplitude, an organism has three broad responses. This range is called ecological amplitude. But what happens when an organism is taken and transported to a completely new environment? What if the conditions there are vastly different from it’s native habitat?Įvery species has a specific range within which it can tolerate ecological changes. This adaptation is what allows it to tolerate small changes in it’s environment be in temperature, humidity or salinity changes. Every organism in this world has a wonderful ability to adapt to changes in it’s surroundings. It will do everything it possibly can, to make sure it survives.
