Physiology
Like most lichens, L. vulpina is highly tolerant of freezing and low temperatures. In one set of experiments, the lichen was able to reactivate its metabolism after 15 hours of cold storage and resume photosynthesis within 12 minutes of thawing. It was also able to start photosynthesis while rewarming, still at below-zero temperatures (°C), suggesting that it may remain active during winter.

Famous quotes containing the word physiology:

“If church prelates, past or present, had even an inkling of physiology theyd realise that what they term this inner ugliness creates and nourishes the hearing ear, the seeing eye, the active mind, and energetic body of man and woman, in the same way that dirt and dung at the roots give the plant its delicate leaves and the full-blown rose.”
—Sean OCasey (18841964)
