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:
“A physician’s physiology has much the same relation to his power of healing as a cleric’s divinity has to his power of influencing conduct.”
—Samuel Butler (1835–1902)
“Now the twitching stops. Now you are still. We are through with physiology and theology, physics begins.”
—Alfred Döblin (1878–1957)
“I have more in common with a Mexican man than with a white woman.... This opinion ... chagrins women who sincerely believe our female physiology unequivocally binds all women throughout the world, despite the compounded social prejudices that daily affect us all in different ways. Although women everywhere experience life differently from men everywhere, white women are members of a race that has proclaimed itself globally superior for hundreds of years.”
—Ana Castillo (b. 1953)
