Q

What is the definition of dormancy?

A

Part of an organisms life-cycle to allow survival during a period when the cost of continued normal metabolic activity would be too high

Q

What is predictive dormancy?

A

Occurs before the onset of adverse conditions - in response to cyclic adversity i.e. seasonal changes
