Term Range of tolerance

The range of physical and chemical conditions that must be maintained in order for a given species to remain alive, grow, develop and reproduce normally.  For example, to ensure the growth of coral reefs, water temperature between 20 and 28° C is required. A temperature increase by only 1 ° C (1.8 ° F) above the range can cause corals to fade or bleach, which can cause their death if the expelled zooxanthellae layer is not restored.

See coral.
