Seaweeds in the cold
Over the more than 1.4 billion years for which they have existed, seaweeds have experienced several episodes of low sea-surface temperature. However, some of the dominant large seaweeds of the colder seas today are of relatively recent evolutionary origin. Raven et al. (pp. 525-536) consider the evolutionary biogeography and ecophysiology of seaweeds that inhabit cold parts of today's ocean.
