Temperature Adaptations Flashcards
Define tolerance.
Body temperature is allowed to vary with ambient temperature.
Define regulation.
Body temperature does not vary with ambient temperature.
Define adaption.
Physiological, biochemical or anatomical modifications occurring within a species over several generations that facilitate an enhanced ability to survive/reproduce in an environment: genetic adaption, GENOTYPIC change.
Define acclimatisation.
Physiological, biochemical or anatomical modifications occuring within the lifetime of an individual that result from chronic exposure to a naturally occurring challenge: PHENOTYPIC change.
Define acclimation.
Physiological, biochemical or anatomical modifications within an individual that result from exposure to a change in a lab/field setting (manipulated): PHENOTYPIC change.
Define conformity.
A condition in which an external challenge induces parallel internal changes, i.e. conformation, poikilo-
Define regulation.
A condition in which an external challenge elicits compensatory actions that maintain the internal milieu, constant, homeo-
Define ectotherm.
Environment determines body temperature.
Define endotherm.
Animal generates internal heat to maintain body temperature.
Define Ambient Temperature (T|A)
Temperature of the animals surroundings,, the most important environmental influence on the animal’s thermal strategy.
