[1] Invasive plants such as the honeysuckle can thrive by altering their morphology in response to changes in the environment,[2] which gives them a competitive advantage.
Another example of a plants phenotypic reaction and adaptation with its environment is how Thlaspi caerulescens can absorb the metals in the soil to use to its advantage in defending against harmful microbes and bacteria in its leaves.
[3] The more immediate responses shown by vascular plants to their environment, for instance a vine's ability to conform to the wall or tree upon which it grows, are not usually considered ecophenotypic, even though the mechanisms may be related.
The most obvious examples are again common observations, as the dwarfing of aquarium fish living in a restricted environment.
[7] In vertebrates, experiments on mice show reduced length of ears and tails in response to being reared in a lower temperature, a phenomenon known as Allen's rule.
