organism may be confined to a limited range of habitats due to the population's thermal optima, while another population may have a different range of habitats open to it due to a different thermal optima for its biological processes. Ultimately the ability to adapt to greater extremes in such a harsh environment as the rocky shores where tide pools are formed may then be discussed in terms of varying environmental thermal optima for different species. Rising temperatures in the face of stable thermal optima also has implications for parasitic disease transmission and where intervention might become necessary.

thermal optima vary for each species and dictate the species' tolerance of environmental conditions that lead to increased heating or loss of mechanisms for cooling. For example, exposure to sunlight when the tide is out, and lack of thermal insulation from the buffering effects of water due to its

In biology a thermal optimum describes the ideal boundaries for biological processes such as growth and development, and is usually characteristic of a species or population. Most biological processes are dependent upon enzymatic activity that can be impacted by the organism's body temperature,
