Temperature Requirements and Biogeography of Antarctic, Arctic and Amphiequatorial Seaweeds
The temperature requirements for growth and survival of cold water seaweeds from both Hemispheres are compared and discussed in relation to the climatic history of the various regions and in relation to the origin of amphiequatorial distribution patterns. Endemic Antarctic species are most strongly...

The temperature requirements for growth and survival of cold water seaweeds from both Hemispheres are compared and discussed in relation to the climatic history of the various regions and in relation to the origin of amphiequatorial distribution patterns. Endemic Antarctic species are most strongly adapted to low temperatures. In contrast, endemic Arctic macroalgae show higher temperature demands and correspond in their temperature responses to many Antarctic cold-temperate species. Arctic cold-temperate species show similar temperature requirements to cold-temperate species from southernmost South America. The temperature requirements of cold-temperate N.
